Abstract

The invention relates to a zero-position centering system and method for an EPS angle. The system comprises an ignition switch module, a power supply module and a main control module, wherein the ignition switch module, the power supply module and the main control module are electrically connected with one another; the ignition switch module is used for sending an enable signal to the power supply module and sending a switch signal to the main control module; the power supply module is used for supplying power to the main control module after receiving the enable signal; and the main control module is used for determining the zero position of the EPS angle according to the received switch signal and carrying out centering according to the zero position of the EPS angle. According to the zero-position centering system for the EPS angle provided by the invention, the zero-position centering cost of the EPS angle can be reduced.

Description

technical field [0001] The invention relates to the technical field of electric power steering, in particular to an EPS angle zero centering system and method. Background technique [0002] The electric power steering system is composed of steering gear, steering column, controller, sensor, power-assisted motor and other parts; the controller receives the ignition signal, vehicle speed, engine speed signal, collects the torque signal from the sensor to output current, and drives the motor to rotate Provide power assist; the sensor (electric power steering system) is divided into models with angle signal and without angle signal. Using the EPS system with angle signal sensor can match the power assist feel according to the steering angle, steering angular speed and other parameters, thereby improving the returning performance , Improve vehicle handling stability and comfort. [0003] When the car using the EPS system with angle signal sensor is produced, the steering wheel a...
