With the popularization of new energy vehicles, more and more people will encounter a problem when buying a car:Is it better to buy a pure electric car or a plug-in hybrid car? The two models have their own advantages, but which one is more suitable for you?Today, Lungu will talk about this topic in detail, hoping to help everyone make a more wise choice.

Wheel valley first on the conclusion:

There is no standard answer to this question, the key lies in your needs and usage scenarios.

If you pay more attention to environmental protection, save money and have stable charging conditions, pure trams are a better choice; And if you have the need for long-distance travel, or the charging conditions are not perfect enough, plug-in hybrid cars can provide greater flexibility.

First, pure electric vehicles

Advantages:

First of all, the biggest feature of pure electric vehicles is thatCompletely driven by electricity, no tail gas emission, especially friendly to the environment.With the development of technology, the cruising range of pure electric vehicles is nowIt can basically reach more than 300 kilometers.High-end models can even run 1000 kilometers. plusWith the gradual improvement of charging facilities, driving a pure tram in the city is no longer as anxious as it used to be.

Saving money is also a highlight of pure electric vehicles.Electricity is much cheaper than oil, especially if you have a charging pile at home, charging at night is more cost-effective and the use cost is very low.In addition, the maintenance cost of pure electric vehicles is also relatively low.Because its structure is relatively simple, there are no complicated parts such as engine and gearbox, and frequent maintenance is not needed.

Insufficient:

But there are also problems. For example, ifThe charging facilities in your place are not perfect enough, so it may be inconvenient to travel for a long time.Although many expressway service areas are now equipped with charging piles, if it is a holiday trip, charging piles may be in short supply. Besides,Winter in the north is a challenge for electric vehicles, and the low temperature will shorten the battery life.

Second, plug-in hybrid car

Advantages:

The advantages of plug-in hybrid cars areIt can use both electricity and oil. When traveling short distances, you can only use electricity to drive and enjoy the same environmental protection and money-saving effect as pure electric vehicles.If you want to run a long distance and the battery runs out, the car can also switch to fuel mode.Avoid the endurance anxiety of pure electric vehicles.

Plug-in hybrid cars are especiallySuitable for those who need to run long distances frequently, or live in areas with inadequate charging facilities.For example, going back to your hometown every year for the New Year and running thousands of kilometers, plugging in a hybrid car can make you go smoothly all the way, without worrying about finding a charging pile.

Insufficient:

However, plug-in hybrid cars also have shortcomings. Although it is very economical to drive with electricity every day, it isOnce you switch to fuel mode, fuel costs are inevitable.Moreover, because it has both an electric system and a fuel engine,Maintenance is more complicated than pure trams, and the cost is relatively high.Many car owners’ friends told me that after using it for a while, they would feelI am charging every day, but I have to maintain the engine regularly, which makes people a little helpless.

Third, how to choose?

Then the question is, should I buy a pure tram or plug-in hybrid? In fact,There is no standard answer to this question, the key lies in your needs and usage scenarios.

• If you usually drive mainly in the city and it is convenient to charge near your home or work, pure electric vehicles are a good choice. It has the advantages of low cost, environmental protection, good driving experience and smooth and quiet acceleration. If you are looking for the economy of daily commuting, pure trams are more suitable for you.

• If you often run long distances, or there are not many charging piles in your place, plug-in hybrid cars are more suitable for you. It has high flexibility, no need to worry about the lack of electricity, and it is very convenient to refuel directly during long-distance travel. If you don’t want to rely entirely on electricity, but want to enjoy the economy of electric mode, plug-in hybrid car is a good compromise.

Fourth, the advantages of trams will become more and more obvious in the future.

Although plug-in hybrid vehicles are more practical in some specific scenarios,But in the long run, the market development prospect of pure electric vehicles is better.With the continuous progress of battery technology and the improvement of charging facilities, pure trams have gradually become the mainstream in the future. Especially now, many car companies are developing more efficient fast charging technology.In the future, the charging time may be greatly shortened, and the advantages of pure trams will become more and more obvious.

Wheel valley summary:

Generally speaking, if you pay more attention to environmental protection, save money and have stable charging conditions, pure trams are a better choice; And if you have the need for long-distance travel, or the charging conditions are not perfect enough, plug-in hybrid cars can provide greater flexibility.

Buying a car is a big deal,I hope my article can help you clear your mind and make a choice that suits you.If you still haveOther car problems, remember to pay attention to me and get more practical knowledge about cars. I’m Lungu. See you next time!

[car home Industry] First of all, let’s restore what happened. The driver said: On the morning of the incident, as usual, he tried to pull over, but found that the brake pedal was too hard to step on, so he turned left and returned to the main road. But the strange thing is that the vehicle began to accelerate crazily, and then the speed of Model Y increased rapidly, reaching a maximum of 198 km/h.

You can also see that the driver avoided electric cars and pedestrians all the way, and the airbag was ejected after hitting the tricycle, and then the car continued to drive until it hit the roadside shop. The driver’s family responded that the driver had been stepping on the brakes during this process, but the brakes were too hard to step on, and he tried to slow down by pressing the P gear, but it was useless.

Then, Tesla responded that the vehicle kept the throttle 100% at high speed, and the brake pedal was not stepped down all the time; During driving, the driver presses the P button four times and releases it quickly, at the same time, the brake light lights up and goes out quickly.

The whole thing has been recorded by video, which is clear to everyone, but Tesla and the owner’s responses are somewhat contradictory, and there are many incredible doubts in the whole incident, which have also caused extensive discussions. The truth of the incident is still under investigation. Let’s discuss the doubts of both sides’ responses from a technical point of view.

Doubt one, what is the probability of brake failure?

According to the owner, the brakes became hard and could not be stepped on, and he suspected that the brakes were out of order.

According to Tesla’s information, the brake system used by Tesla Model Y is Bosch’s ibooster brake product. This product has now come to version 2.0, and many new energy vehicles currently on sale are equipped with Bosch’s iBooster.

IBooster is a revolutionary technology compared with traditional brakes, which cancels the design of vacuum pump. When the driver steps on the brake pedal, the brake position sensor will tell the signal to the vehicle controller. After calculation, the vehicle controller will distribute the braking force. One part of the braking force is provided by the regenerative braking of the motor, and the other part is generated by the brake cylinder, which together help to brake. The following figure shows the working principle diagram of iBooster.

Let’s take a look at the working schematic diagram of the whole brake system. When people step on the brake pedal with a force of 200N (about 20 kg), this force will be amplified a little, and finally the force on the brake disc will reach 18500N N. In addition, the Vacuum Brake Booster in the above picture is now replaced by iBooster.

At this time, some people questioned that iBooster is an electronic component, and electronic components are not as stable as mechanical components, so iBooster sometimes fails. Therefore, Bosch’s iBooster has two backup measures to deal with possible failures.

Backup measure 1:

If the electronic component iBooster in the above picture fails, there will be no braking assistance, and the brakes will become hard and a little difficult to step on. At this time, ESP will realize that iBooster is broken and loses its power, so it will take over and provide braking power (active pressurization). The active pressurization of ESP will be accompanied by strong vibration and noise.

At this time, for the driver, the experience is that stepping on the brakes requires more strength, but it will not be impossible to step on it. For example, stepping on the brakes with 200N strength can provide at least 0.4g deceleration.

Backup measure 2:

If both iBooster and ESP are broken by accident (the probability of actual occurrence is very small), at this time, the whole braking system enters mechanical mode without any assistance, and how much deceleration can be achieved depends on how hard the driver steps on the brake pedal.

At this time, the appearance is that the brakes become hard and difficult to pedal, but the laws and regulations mandate that the brake pedal at this time can produce at least 0.25g deceleration under the strength of adults (including adult women) with 500N N.

Therefore, from the above analysis, it can be seen that "brake failure" itself is an imprecise statement. The brake can only lose its power, but it is almost impossible for the brake to fail, because in the end, it has mechanical braking to cover the bottom. If the brakes get hard, don’t doubt your feet at this time, and don’t hesitate to step on them.

Doubt two, do you want to carry the pot with a single pedal?

Stopping the car is only one aspect. Another big doubt of the Chaozhou accident is why the vehicle "suddenly accelerates". Whether the driver stepped on it wrongly or the program error of the car itself was out of control.

First of all, public opinion thinks that the driver stepped on the wrong foot because of Tesla’s single pedal mode. Should the single pedal carry the pot?

From a technical point of view, the single pedal is indeed a controversial thing. First of all, the name is very confusing, which makes many people think that this kind of car has only one accelerator pedal and no brakes.

The biggest change of single pedal mode to people is that it affects people’s driving habits. In the past, the car accelerated when stepping on the accelerator and slowed down when stepping on the brake, while in the single pedal mode, the car accelerated when stepping on the accelerator and slowed down when releasing the accelerator, which is similar to the sense of deceleration when stepping on the brake. After a long time, the driver will tie the accelerator and the brake together. When there is an emergency, it is easy to step on the accelerator with one foot, so the smart electric car now.

However, a trained driver, or a driver who can have a deep understanding of the single pedal mode, should always put his feet on the brakes, keep calm, and step on the brakes in time when he needs to slow down quickly.

For this question, whether the single pedal should take the blame for this matter, I think that the single pedal does bring about an increase in the proportion of misoperation of the accelerator when braking, but most of the misoperation is instantaneous, and most drivers will react after the instantaneous mistake and correct it in time. The strange thing about this incident is that the whole process lasted for about a minute and the car advanced 2.6 kilometers. Will someone really step on the accelerator by mistake for so long?

Therefore, it comes to the third doubt, what is the probability of sudden acceleration of the car?

Doubt 3: Unexpected acceleration probability of automobile?

Unexpected acceleration of automobile is a very professional statement in the automobile industry and a famous failure mode in the field of functional safety.

Unexpected acceleration: that is, the acceleration of the car is against the driver’s will. The driver did not step on the accelerator but the car kept accelerating.

The sudden acceleration of automobiles is nothing new in the industry. As early as 2000-2010, Toyota’s "unable to stop" in the United States caused 89 deaths, which is the "brake door" incident of Toyota.

In order to investigate these unstoppable Toyota cars, NHTSA and NASA launched an investigation on Toyota cars, including looking at the source code of Toyota cars. During 2011-2013, embedded software experts Michael barr and Philip Koopman started with the software, and looked at nearly 300,000 lines of code of Toyota in 18 months, and found some bugs in the software, which would lead to "unexpected acceleration" of the car and lead to out-of-control of the car.

Therefore, Toyota’s brake door also led to the development of later automotive embedded software specifications, and also led to the development of automotive electronic and electrical functional safety, and functional safety is to prevent any behavior against the driver’s will, which will affect people’s life safety, especially the sudden acceleration with great harm.

Back to this incident, Tesla’s software architecture and functional safety design has always been a mystery in the industry. No one knows what his car software architecture is like, including what operating system to use and whether it is functionally safe.

Therefore, to answer this question: the sudden acceleration of cars has almost disappeared in the new era, but what Tesla is really like needs more data to explain.

Speaking of data, it is actually the EDR data in Tesla car, which can record the running information of the vehicle before and after the incident.

Doubt 4: Can EDR restore the truth?

The state has mandatory regulations for automobile data recording system. According to the national standard GB39732:

"Passenger cars should be equipped with an event data recording system (EDR) that meets the requirements of GB 39732; If equipped with a vehicle-mounted video driving recording system that meets the requirements of GB/T 38892, it shall be deemed as meeting the requirements. This standard will be implemented for newly produced vehicles from January 1, 2022.

EDR, also known as automobile event data recording system, is a mandatory requirement for new energy vehicles in China. This EDR system records some key information of vehicles, including throttle position, brake pedal position, vehicle speed, etc., and also specifies the recording format, recording frequency and reading mode of these data.

For example, the information about the accelerator pedal and brake position that everyone cares about is stipulated in the regulations:

It can be seen that the data of brake and accelerator pedal are specific position information (percentage), which can reflect the real position of accelerator and brake in general.

Moreover, the EDR system can also be stored when there is no power, and the data is stored in the protected area, which cannot be tampered with and should not be deleted. If the third party has the ability to read the EDR data, it can read the real data.

In general, EDR can record the true accelerator pedal value (that is, the percentage of the driver’s depression, whether it is 50% or 100%). But this is not the original value. The original value should be the electric signal of throttle and brake, that is, a voltage signal of 0-5V, which will be converted to get the percentage.

For example, the brake or throttle position will be sampled by sensors to measure their real position; The original value sampled by the sensor is an electrical signal in the range of 0-5V. If the original electrical signal is wrong at the beginning, all the data after that are wrong.

At the same time, the original electrical signal becomes the percentage position information of throttle and brake after a series of conversion, which is the information that we can read by EDR. It is impossible to know whether there will be any fault in this conversion process.

So, to answer question 4, can EDR tell the truth?

It can be done 99% of the time, but it does not rule out that the system is wrong at the beginning, so the recorded values are also wrong. It is of course possible to explain a wrong phenomenon with a wrong data, but obviously, this "explanation" has deviated from the truth.

Anyway, let the bullet fly for a while. (Text/car home industry commentator Zhang Gong)

　　BEIJING, Beijing, July 27 (Zhang Ni) Recently, the region including the middle and lower reaches of the Yangtze River and most of the south of the Yangtze River experienced the strongest high temperature this year, and the Central Meteorological Observatory continued to sound the orange warning of high temperature. Shanghai, Hubei, Chongqing and other places have recently sounded the first high-temperature red warning this summer. In addition, the power grid load in some areas of Jiangsu and Anhui has hit record highs, and the high-temperature "barbecue" mode has been opened in many places across the country.

　　The high temperature warning continues to sound that the somatosensory temperature in some areas exceeds 50 C.

　　At 18: 00 on the 26th, the Central Meteorological Observatory continued to issue a high-temperature orange warning. It is estimated that there will be high temperature of 35 ~ 39℃ in northern South China, Jiangnan, Jianghuai, Jianghan, southern Huanghuai, southern North China, eastern Sichuan Basin, Chongqing, northern and eastern Guizhou, Xinjiang, northwestern Gansu and western Inner Mongolia during the day on the 27th.

　　Among them, the highest temperature in parts of central and northern Zhejiang, eastern Anhui, southern Jiangsu, northeastern and western Jiangxi, southeastern and western Hubei, eastern and northwestern Hunan, and Chongqing can reach 40 ~ 41℃.

　　According to China Weather Network, since late July, the strongest high temperature weather has appeared in the middle and lower reaches of the Yangtze River and most parts of the south of the Yangtze River this year, and the somatosensory temperature in some areas is as high as 50℃.

　　On the 25th, the range and intensity of high temperature reached its peak, with high temperature of 35℃ or above prevailing in Jianghuai, south-central Jianghan, south of the Yangtze River, south of China and northeast of southwest China, with the highest temperature of 40℃ or above in some areas of northwest Hubei, central Hunan and western Zhejiang.

　　Shanghai, Hubei, Chongqing and other places have recently sounded the first high-temperature red warning this summer and entered the "barbecue" mode. As of the 24th, the area affected by high temperature affected about 700 million people.

　　Why does the hot weather continue to flourish?

　　Why is this round of hot weather so strong? Ma Xuekuan, chief forecaster of the Central Meteorological Observatory, told the media that this round of high temperature weather is due to the subtropical high stretching westward and lifting northward, and the gradually increasing subtropical high will continue to control the southern region.

　　The place controlled by subtropical high will mainly be sunny and hot with little rain, and the ground temperature will gradually rise due to the influence of solar short-wave radiation during the day. At the same time, downward flow is also prevalent in the high-pressure control area, forming a certain sinking and warming effect. Under the combined action of radiation warming and subsidence warming, high temperature weather will occur.

　　Ma Xuekuan said that at present, this hot weather process will continue, and the hot weather in northern South China, Jiangnan, Jianghan, Jianghuai, Chongqing and other places will run through to the end of July, and the temperature in some areas will reach 39-41 C.

　　In some areas, the electricity load is record-breaking, and the power supply is tight.

　　The continuous high temperature weather has caused the power grid load in many areas to break records.

　　On the 24th, the maximum load of Hefei Power Grid in Anhui Province reached 5,171,400 kilowatts, a record high this year. On the 25th, the power grid load continued to climb to 5.532 million kilowatts, breaking the historical record for two consecutive days.

　　At present, Hefei Power Supply Company has started the emergency plan for power grid operation and emergency command, eliminated hidden dangers, increased the strength of emergency repair personnel, strengthened the 24-hour emergency duty system and responded quickly.

　　In Jiangsu, at 13: 10 on the 25th, the largest dispatching power load in the province exceeded 90 million kilowatts, reaching 92.38 million kilowatts, a record high. Among the 13 cities in Jiangsu province, except Lianyungang, the electricity load of the other 12 cities has reached a record high.

　　From 23rd to 25th in Shandong Province, the highest load of the whole power grid hit a record high for three consecutive days, reaching 68.386 million kilowatts on 25th. Relevant departments have organized and started orderly electricity consumption measures, and some high-energy-consuming industries have been "restricted".

　　High-temperature workers who have died of heatstroke in many places should be vigilant.

　　The hot weather not only makes the power grid unbearable, but also affects people’s health. Recently, the news of death caused by high temperature weather has been exposed one after another, which makes people really sweat.

　　According to incomplete statistics, as of noon on the 25th, Jiangsu has reported more than 120 cases of heatstroke and nearly 20 cases of critical illness. Among them, the most is Nanjing, with more than 70 cases, only one case is severe; Zhenjiang has the largest number of critical cases, reaching 11 cases; In addition, Suzhou, Yancheng, Nantong, etc. have reported critical or dying cases. Death due to heatstroke, except Zhenjiang, Yancheng and Zhangjiagang each have one case.

　　In addition, there are also cases of death from heat stroke in Anhui and Shanghai.

　　Wang Junyu, deputy chief physician of the emergency department of Beijing Chaoyang Hospital affiliated to Capital Medical University, said in an interview with Zhongxin. com (WeChat WeChat official account: cns2012) that heat stroke is actually a severe heatstroke, which is a serious clinical syndrome that the core temperature of the human body rises rapidly due to exposure to high temperature and high humidity, exceeding 40℃, accompanied by skin burning, disturbance of consciousness and other multiple organ system injuries.

　　The incidence of heatstroke is closely related to three environmental factors, namely, high temperature, high humidity and windless environment. Therefore, workers exposed to high temperature for a long time are prone to heat stroke.

　　"Once the symptoms of heatstroke appear, we must first move the patient to a cool place, strengthen air circulation, and let the patient replenish water in time to relieve the symptoms. Once the patient has symptoms such as unconsciousness and convulsions, he must be sent to the doctor in time and cannot handle it himself, so as not to delay the illness. " Wang Junyu stressed.

　　The reporter learned that in addition to heat stroke, the incidence of cardiovascular and cerebrovascular diseases and respiratory diseases caused by high temperature has also shown an upward trend recently.

　　Wang Junyu told reporters that taking his department as an example, the number of patients with the above diseases has increased by about 10% to 20% in the past week, mainly middle-aged and elderly people.

　　Tips for heatstroke prevention and cooling: Pay more water in hot weather and avoid being greedy.

　　The "high-temperature barbecue" mode has been opened in many places. What measures should ordinary people take in their daily travel?

　　In this regard, Wang Junyu suggested that, first of all, citizens should try to reduce going out, especially at noon. When going out, it is best to prepare for heatstroke prevention and cooling.

　　In addition, people, especially middle-aged and elderly people with cardiovascular diseases, must replenish water in time, drink more boiled water every day, and supplement light salt water when sweating a lot.

　　"In hot weather, if the elderly don’t replenish enough water, it will easily lead to blood concentration, which will induce myocardial infarction and cerebral infarction. In addition, in hot weather, the air circulation is not smooth, and patients with respiratory diseases are more prone to illness. Therefore, these people should be extra careful. " Wang Junyu said.

　　However, he also reminded that it is forbidden to be greedy in hot weather, because drinking too much cold drinks will aggravate the stimulation of the intestines and damage human health. (End)
