Recently, Xiaomi Automotive Technology Co.
, Ltd.
announced a new patent "steering wheel detachment detection method, device, readable storage medium and vehicle"
.
The abstract shows that the patent relates to the field of
autonomous driving.
Even in some special use scenarios, the patent can accurately detect whether the steering wheel is out of hand, provide accurate information for the assisted driving system, and improve driving safety
.
The disclosure of this patent relates to a steering wheel off-hand detection method, device, readable storage medium and vehicle, and relates to the field of
autonomous driving.
The method includes: periodically obtaining the capacitance value collected by the capacitive sensor for the vehicle's steering wheel; obtain the torque value collected by the torque sensor for the steering wheel; Periodically determine the amount of capacitance value change according to the capacitance value and the predetermined capacitance reference value; When the capacitance value change is less than the predetermined capacitance value change threshold, and the working state of the capacitive sensor is not in an active state, the tamper detection result
is determined according to the working state of the capacitive 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, providing accurate information for the assisted driving system and improving driving safety
