Brake control method, device, storage medium and vehicle

Abstract

The present disclosure relates to a brake control method, device, storage medium and vehicle. The method includes: obtaining the initial current of the brake motor when power-on; obtaining the required clamping force in response to receiving the braking command, and determining the target rotation angle according to the required clamping force; according to the currently stored initial current of the brake motor The position information and the target rotation angle control the rotation of the brake motor to generate the required clamping force. Among them, the initial position information is used to indicate that when the brake motor is powered on, if the brake pad is moved from the initial position to the contact point position, the brake The angle at which the motor needs to rotate; if the initial current is less than or equal to the preset current threshold, the real-time current of the brake motor is acquired during the process of controlling the rotation of the brake motor, and the initial position information of the brake motor is updated according to the real-time current. In this way, the relative distance between the brake pad and the brake disc can be accurately detected without installing a displacement sensor, which reduces the cost of the whole vehicle and improves the intelligence of vehicle control.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a braking control method, device, storage medium and vehicle. Background technique [0002] Compared with traditional hydraulic braking systems, electronic braking systems are more and more widely used in vehicle braking systems. In the related technology, it is usually necessary to install a displacement sensor on the direct push part of the brake caliper in the electronic braking system, and use the displacement sensor to collect the relative distance between the brake pad and the brake disc, and control the brake according to the distance information. The motor works. However, the displacement sensor has high requirements on the working environment, especially the high requirement on the ambient temperature, while the working environment of the electronic braking system is relatively harsh, the measurement accuracy of the displacement sensor in this working environment i...
