Xiaomi EV discloses patent related to steering-assist control

Shanghai (Gasgoo)- Xiaomi EV has made public a newly granted patent related to steering-assist control, underscoring its ongoing push in autonomous driving technologies, according to a notice via Chinese enterprise information query system Qcc.com on September 23.

The patent abstract indicates that the technology is designed for autonomous driving applications. It describes a process in which the system monitors the vehicle when steering assist is temporarily disabled, determines whether conditions allow its safe reactivation, and then restores the feature when appropriate.

Xiaomi EV claims the method helps reduce unnecessary toggling between deactivation and reactivation of steering assist. This is expected to improve the safety and reliability of automated driving functions, while offering drivers a smoother overall experience.

Xiaomi EV currently sells three models — the SU7, SU7 Ultra, and YU7. As the company's first electric vehicle, the SU7 has been at the center of market attention since it hit the market. Its advanced driver-assistance system (ADAS) is among the model's most heavily marketed features and continues to draw widespread discussion.

However, Xiaomi EV is recalling 116,887 units of its SU7 Standard Edition all-electric sedan due to safety concerns linked to its driver-assistance system, according to a filing recently issued by China's State Administration for Market Regulation ("SAMR"). The recall covers vehicles manufactured between February 6, 2024 and August 30, 2025.

According to the filing, the issue may arise when the L2 highway navigation assist function is in use. Under certain extreme scenarios, the system may not recognize hazards quickly enough, provide adequate warnings, or execute sufficient corrective actions. Regulators cautioned that if drivers fail to take control promptly, the risk of collision could rise, creating a clear safety hazard.

Unlike traditional recalls that require drivers to visit service centers, Xiaomi EV is implementing over-the-air (OTA) updates — a practice that has become increasingly common in China's auto industry over the past two years.

Xiaomi EV confirmed that it will provide free software upgrades remotely for affected car owners through OTA technology, allowing users to complete the safety fix without visiting dealerships.

It is worth mentioning that Xiaomi EV reported a solid sales volume in August, with more than 30,000 units delivered during the month.
