Xiaomi Motors "steering wheel off -hand detection patent" announced: autonomous driving further

Drive China August 15, 2022

Recently, according to the platform, Xiaomi Automobile Technology Co., Ltd. announced the new patent "steering wheel removal detection method, device, readable storage medium and vehicle", and apply for the announcement number CN114852092A. Summary shows that the patent involves the field of autonomous driving. Even in some special use scenarios, this method can accurately detect whether the steering wheel is off, providing accurate information for the auxiliary driving system, and improving the safety of driving.

This method includes: the capacitance value of the capacitor sensor collected for the Vehicle steering wheel; obtain the torque value of the torque sensor collected for the steering wheel; the periodicity of the periodicity of the capacitance and the scheduled capacitance accuracy is determined; When the volume of the capacitance value is less than the scheduled capacitor value change threshold and the working state of the capacitance sensor is not in an effective state, the work status and torque value of the capacitance sensor are determined according to the working status of the capacitance sensor. In this way, even in some special use scenarios, it can accurately detect whether the steering wheel is off, providing accurate information for the auxiliary driving system, and improving the safety of driving.

It is worth mentioning that Xiaomi has recently demonstrated the ability of autonomous driving technical algorithms and the ability to cover the whole scene. Lei Jun said that Xiaomi's autonomous driving technology has adopted a full -studded technical layout strategy of a full stack. The project has achieved exceeding expectations. Target 2024 Enter the first autonomous driving camp.
