Xiaomi CEO Lei Jun Delivers SU7 EVs Amid Brake Failure Software Misidentification Response

Xiaomi's CEO Lei Jun personally delivered the first batch of SU7 EVs, following the company's official response attributing brake failure to a software misidentification.

Xiaomi Addresses SU7 Brake Failure Incident as Software Misidentification, Ensuring Vehicle Safety

For those unfamiliar with the situation, an SU7 vehicle was hauled to the Changsha Service Center early on May 9. According to Gizmochina, the store staff examined the car and advised us that there was no mechanical breakdown or damage to the brake system. After running the "self-inspection" program, the brake failure warning message disappeared and the vehicle appeared to function normally.

Wang Hua indicated that it was a software misidentification. He said that the problem had been resolved and that there was no reason to be concerned about the car's safety. He contacted an engineer from the Automotive Department to resolve the issue. Here's what happened with the automobile.

The vehicle's main brake controller (DPB/BCP) system was "misidentified and degraded" during analysis. It initiated the backup braking mechanism, and the auxiliary brake controller (ESP/BCS) began responding directly to provide braking and deceleration for the car. Similarly, the vehicle's huge screen caused the brake system to fail.

When the backup braking system is activated, the ESP draws the DPB brake fluid to enhance the braking pressure required to bring the car to a stop. Because the ESP drew the braking fluid away from the DPB, the pressure in the brake master cylinder dropped rapidly, which the driver could feel while pedaling.

Because the braking system shifts between primary and secondary, the original cylinder pressure value of the main brake is reduced to zero. However, the SU7 never lost its braking power. Fortunately, the ESP took care of the situation, and the vehicle remained under control.

Although the car returned to normal, the user was offered a return/exchange of the vehicle. Xiaomi Auto was also willing to cover expenditures associated with the vehicle's return/exchange.
