Document Type and Number:
WIPO Patent Application WO/2021/004441
Kind Code:
A1
Abstract:
Disclosed are a steering wheel position checking system and a checking method, the steering wheel position checking system comprising: a toothed disc (22) having several toothed grooves, and magnetic elements being arranged at intervals at the several toothed grooves; a locking mechanism, mounted inside a side wall of a steering wheel tubular column (21), the locking mechanism being arranged corresponding to the toothed disc (22) of a steering wheel (14), and the locking mechanism comprising a lock pin (212) having a Hall element (213), and the lock pin (212) being snapped into the toothed groove when the system is powered off; and a detection device connected to the Hall element (213), wherein when the system is powered on again, an angle value corresponding to the position of the steering wheel is checked according to an output signal of the Hall element (213). The system effectively ensures a one-to-one correspondence relationship between the position of the steering wheel and the position of a vehicle wheel after the system is powered off and restarted, completes checking of the position of the steering wheel at the moment of energization, simplifies the checking process, and improves the checking precision.
