Recently, Xiaomi Automotive Technology Co., Ltd. announced a new patent "steering wheel release detection method, device, readable storage medium and vehicle", application announcement number CN114852092A. According to the summary, the patent relates to the field of self-driving. Even in some special use scenarios, this method can accurately detect whether the steering wheel is out of hand, provide accurate information for the auxiliary driving system, and improve driving safety.

The invention relates to a steering wheel release detection method, a device, a readable storage medium and a vehicle, which relates to the field of self-driving. The method includes: periodically obtaining the capacitance value collected by the capacitance sensor for the vehicle steering wheel; obtaining the torque value collected by the torque sensor for the steering wheel; periodically determining the change of the capacitance value according to the capacitance value and the predetermined capacitance reference value When the change of the capacitance value is less than the predetermined change threshold of the capacitance value, and the working state of the capacitance sensor is not in an effective state, the release detection result is determined according to the working state of the capacitance sensor and the torque value. In this way, even in some special use scenarios, it can accurately detect whether the steering wheel is out of hand, provide accurate information for the auxiliary driving system, and improve the safety of driving.

Recently, Xiaomi has demonstrated the algorithm of self-driving technology and the ability of full scene coverage. Lei Jun said that Xiaomi self-driving technology adopts a full stack self-developed technology layout strategy, and the project has made more progress than expected. The goal is to enter the first camp of autopilot in 2024. Up to now, Xiaomi has invested 3.3 billion yuan in research and development in the field of self-driving, and has set up a top R & D team with more than 500 people. at the same time, through wholly-owned mergers and acquisitions and industrial investment in upstream and downstream enterprises, Xiaomi has steadily promoted its medium-and long-term industrial layout in the field of self-driving.
