Abstract

The invention belongs to the technical field of vehicles, and relates to a torque correction method, a vehicle and a computer readable storage medium. The method comprises the following steps of acquiring torque correction factors, when the torque correction factors meet torque correction conditions, executing torque correction response, wherein the torque correction factors comprise the current push rod stroke; acquiring basic torque and limiting torque according to the current push rod stroke; acquiring target torque according to the basic torque and the limiting torque. Therefore, reasonable target control torque can be output for pressure relief return control in the torque control process of the completely-decoupled electronic power-assisted brake system, so that noise caused by shell damage or shell collision is prevented, the technical effects of low implementation cost and clear control thought are achieved. And the problem of noise caused by shell damage or shell collision can be well solved while the pressure relief intention of a driver can be accurately responded.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a torque correction method, a vehicle and a computer-readable storage medium. Background technique [0002] At present, there are few mature and fully decoupled electronic power brake system control technology solutions, and there are fewer patents on the existing pressure relief return control solutions that better protect the shell and control noise under various working conditions. [0003] In the torque control strategy based on the electric power brake system in the prior art, when the base load of the whole vehicle changes, the control target torque of pressure release and return needs to change according to the change of the base load. If the calculated target torque of the motor is too large, it will hit the shell and generate noise; if it is too small, it will not return to the proper position and cannot replenish the pipeline. How to obtain an appropriate ...
