Abstract

The invention discloses a steering assist compensation method, system and vehicle. The method includes: obtaining the first basic compensation torque corresponding to left steering and the second basic compensation torque corresponding to right steering; when the vehicle is running, according to the vehicle speed A corresponding compensation coefficient is determined according to the rotation speed of the steering wheel; and a compensation value of the steering assist is obtained according to the compensation coefficient and the first basic compensation torque or the second basic compensation torque corresponding to the current steering wheel rotation direction. This method can realize the differential compensation of the left and right steering forces of the vehicle, effectively improve the problem of uneven left and right steering forces, thereby improving the steering feel and making the driver more comfortable when driving.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a steering assist compensation method, system and vehicle. Background technique [0002] With the advancement of electronic technology, the application of electronic products in automobiles is becoming more and more popular. Electric power steering systems are widely used due to factors such as compact structure, energy saving and emission reduction, and rich tuning functions. People's requirements for vehicle electric power steering systems have changed from the initial steering function requirements to comfort requirements. It has developed functions such as automatic parking and lane keeping assistance. [0003] In related technologies, a fixed steering force compensation standard is usually set when the vehicle leaves the factory, that is, a fixed compensation value is calibrated in advance. However, due to differences in component manufacturing and vehicle assembly, di...
