Speaking of brake problems, we have to mention the "story" that happened at the 19th Shanghai Auto Show in 2021, a woman climbed onto the exhibition car of the Tesla booth and shouted loudly: "Tesla brake failure" incident; this matter came out, quickly swept the entire car circle, and caused a series of storms in the follow-up, until today, under the major car platforms, about Tesla's content, you can also see the ridicule about the "brake" event, why Tesla will cause "brake failure"?
Pure electric vehicles need to match electronic assist brakes to correspond to the energy recovery system, so that pure electric vehicles will waste kinetic energy again into electrical energy, secondary recycling; and Tesla using Bosch's iboster wire brake system needs to match with Tesla's internal code, in the matching, it is likely that there will be occasional matching bugs, resulting in brake failures.
For car companies and insurance companies, only by the owner's one-sided words, it is impossible to prove whether the cause of the accident is a vehicle failure, resulting in the Tesla incident fermenting for a long time without a perfect answer; when the accident occurs, there is no link that can effectively monitor whether it is the reason for the vehicle itself or the owner's driving reason, which is also the biggest factor that currently plagues consumers.
New cars are mandatorily equipped with "artifacts"
In April 2021, the Ministry of Industry and Information Technology revised the "Technical Conditions for the Safety of Motor Vehicle Operation" to require that from January 1, 2022, newly produced passenger cars must be equipped with an EDR system to record events for vehicles when they go off the line.
EDR system, also known as black box, the device can record the vehicle operation data before and after the accident, when the vehicle collides or the speed changes and other accidents, it will be forced to trigger, start recording, so that you can monitor abnormal data throughout the process when there is an event such as "brake failure" in Tesla, and clearly determine the main cause and responsibility of the accident.
Pure electric vehicle era, I believe many users have heard a sentence, "software-defined car", from the current pure electric vehicle development curve, the current electric vehicle, in addition to the basic hardware infrastructure, software algorithms in the electric vehicle interior a large number of deployment, whether it is the basic driving control, car machine system operation UI, or automatic driving, and even motors and other hardware deployment logic, are software-defined.
Traditional fuel vehicles, the necessity of EDR existence is very small, with the pure electric vehicle complex software logic and algorithm, as well as electronic control system, automatic driving technology and other multi-dimensional software ecology, there are more undetermined system failures and driver misoperation and other issues, therefore, EDR in the future development trend of new energy, become the car just need.
What are the implications of the advent of EDR?
First of all, when an accident similar to Tesla's "brake failure" occurs in the vehicle, the EDR system can more accurately find the root cause of the accident, whether it is the cause of the vehicle itself or the driver's misoperation, and because of the "referee" of EDR, it can also allow the traffic system and insurance companies to clarify the accident responsibility more quickly, deal with the accident more quickly, improve the processing efficiency, more accurately find the cause of the accident, and there will be no complex disputes.
Secondly, according to the information, the cost price of the EDR system is about 300-500 yuan, and the car company can overcome the impact and will not increase the cost of consumer car purchase, so the new car is equipped with an EDR system on a large scale and will not affect the price of the new car.
Write at the end
Although the emergence of EDR will not be greatly affected by the automotive industry and prices, due to the large proportion and volume of the domestic passenger car market, with the mandatory equipment of EDR, the industrial chain such as basic sensors in EDR equipment will inevitably be greatly affected, and for consumers, it is undoubtedly a reassuring pill for the purchase of pure electric vehicles.
With the general trend of "software-defined cars", the future of pure electric vehicles and other multi-dimensional will encounter problems about software, and the mandatory EDR system is undoubtedly to play a better regulatory role for the industry, in the face of market changes and the promotion of the industry, it is effective and beneficial, so the EDR system will also play an auxiliary pure electric vehicle industry market to develop.
