Anti-interference signal power-assisted steering control method

Abstract

The invention relates to an anti-interference signal power-assisted steering control method. The method comprises the following filtering logics that S1, when a vehicle speed is less than 20km / h, an EPS electric power steering system analyzes according to the actual vehicle speed; S2, when the vehicle speed is greater than or equal to 20 km / h and less than or equal to 140 km / h, if the vehicle speed step exceeds 10 km / h, the EPS does not update the vehicle speed, and analysis is still performed according to the vehicle speed received last time; and S3, when the vehicle speed is greater than 140 km / h, the EPS does not update the vehicle speed, and the EPS outputs hand power according to the vehicle speed of 140 km / h. The method has the advantages that the corresponding power-assisted steering can be obtained in real time according to the vehicle speed for calibration, vehicle speed analysis can be better carried out on EPS input information, therefore, judgment of a driver is better facilitated, and the safety and comfort of the whole vehicle during steering are guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle speed, in particular to a steering assist control method for anti-interference signals. Background technique [0002] Electric Power Steering (EPS) refers to a power steering system that relies on a motor to provide steering torque. One end of the vehicle's EPS is connected to steering components (such as a steering wheel, steering handle), and the other end is connected to a steering machine, wherein the steering machine can drive the front wheels. The user turns the steering component with a small force, and the EPS controls the motor to provide steering assist torque to the steering machine based on the steering torque, steering angle, and vehicle speed of the steering component, thereby driving the front wheels to achieve steering. [0003] Electric steering column power steering requires an input vehicle speed signal, and the power assist is controlled according to the speed. The transmissio...
