Ask the M5 "ride" BYD dolphin! Official release of accident description

AutoBeta( Report--

On November 13, the collision of the M5 smart driver version of "riding" BYD dolphin attracted widespread attention. Through two video clips from different angles at the scene to restore the accident, when the white BYD dolphin drove to the intersection, it was found that a M5 was about to reverse to the main road, so the dolphin owner stopped and waited. But at this time, the M5 suddenly accelerated to reverse the car, hit the dolphin with a very strong collision force, and was about to overturn the vehicle. In the end, the entire rear part of the M5 was pressed on the dolphin's body, and the accident caused the BYD dolphin's main driver's side door to be sunken to a certain extent.

Today, the AITO official issued a statement on the matter: November 13, 2023, Dongguan Chabu users in the test drive occurred an accident. After background data analysis and confirmation with the test driving user, the user mistakenly mistook the acceleration pedal for the brake pedal, which led to the accident. According to the accident vehicle data, the car pressed the throttle 100% to the bottom twice after it was put into R gear for a total of 4 seconds, with an acceleration of 5.83m/s2, a maximum speed of 3180 rpm, a maximum torque of 300N ·m and a maximum speed of 32.82km/h, the Q said. At present, the vehicles of both sides have been compensated and repaired by test driving insurance, but fortunately, no one was injured in the accident.


The M5 series smart driving version, which was first unveiled in April this year, is the first model with both Huawei ADS 2.0 high-end intelligent driving system and Hongmeng intelligent cockpit 3.0, relying on lidar and high-precision maps to achieve valet parking assistance, urban lane cruising assistance, urban intelligent driving assistance and other functions. As a new energy vehicle equipped with Huawei ADS 2.0 high-level intelligent driving system for the first time, the advanced intelligent driving version of the AITO M5 series has added lidar and side-view camera to the hardware, and the computing unit has also been replaced with Huawei's self-developed MDC intelligent driving computing platform, which can provide it with better driving assistance.

Mr Yu said Huawei ADS 2.0 was infinitely close to L3 advanced intelligent driving, which could reduce traffic accidents caused by inattention and complex road conditions by 90 per cent.

Why didn't AEB intervene? According to the user's manual, the backward automatic emergency braking system detects the driving environment in front of the vehicle in real time through sensors such as cameras. Braking is performed automatically when the vehicle reverses at a speed of about 1km/h-12km/h and is about to collide with a stationary or slow-moving two-wheeler or vehicle (excluding stationary vehicles). When braking, the vehicle will turn on the brake lights at the same time.

According to the working logic of AEB, it is similar to pressing the throttle to the bottom twice after the video vehicle is put into R gear for a total of 4 seconds, and the maximum speed has reached 32.82km/h. At this time, the system will determine that the driver does not need system intervention, so usually AEB will not be triggered in this case.

AEB is one of the selling points of Huawei ADS 2.0 high-level intelligent driving, and it is also one of the features that Huawei values very much. That is why there was a "AEB dispute" between Yu Chengdong and he Xiaopeng some time ago, but AEB is not omnipotent, and it also has limitations, such as more complex scenes, sensor states, and other obstacle objects that may affect the normal effectiveness of AEB.

Although the current technologies of intelligent driving assistance for new energy vehicles are quite mature, they can not blindly rely on these things in the process of driving. before self-driving comes, the main body of vehicle driving is still people. always observe the road conditions and be ready to take over at any time.
