Steering wheel angle sensor based on the idling torque compensation method, and a vehicle system

The present invention relates to a steering wheel angle sensor based on the idling torque compensation methods, systems, and automotive. Said method comprising the steps of: mounting a steering wheel angle sensor in a vehicle steering system, and the steering wheel angle sensor calibration, is determined for each operating position of the steering wheel through its respective operative position information and the steering wheel is converted into the corresponding calibration of the on-board controller for receiving the steering wheel angle signal and calculating the rate of change of the steering wheel angle and steering wheel angle signal, steering angle and the current rate of change of engine speed, and ambient temperature; the angle signal output by the vehicle network determining a vehicle speed in the power steering apparatus currently required steering torque compensation value idle condition, then the torque demand value based on the steering torque reserve offset value and a vehicle other than the vehicle the total torque is determined to summarize the reservation requirement value, thereby controlling the intake air of the engine and the ignition timing adjustment.
