Steering wheel position calibration system and calibration method

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.

Description

technical field [0001] The invention belongs to the field of hydraulic steering, and relates to a steering wheel position verification system and a verification method. Background technique [0002] As low-speed and heavy-duty vehicles such as engineering vehicles and special operation vehicles are widely used in various industries, it improves the production efficiency of operations and reduces production costs. The existing low-speed heavy-duty operating vehicles adopt hydraulic steering systems due to the special chassis layout structure and the torque requirements for the steering system required by the working environment. [0003] Due to the inevitable leakage in the hydraulic system, there is no one-to-one correspondence between the steering wheel and the steering wheel of the low-speed heavy-duty vehicle, so the operator cannot turn the vehicle accurately when driving the vehicle. security poses a great threat. The hydraulic synchronous steering system can realize ...
