Abstract

The invention relates to a braking force estimation method, a braking force estimating device, a storage medium and a vehicle. The braking force estimation method comprises the following steps of: acquiring parameter information of a brake motor of the vehicle; acquiring the current feedback force of a brake pad according to the parameter information and a preset feedback force estimation model ofthe brake pad of the vehicle; and acquiring the current braking force of the vehicle according to the current feedback force. Compared with the prior art, the braking force estimation method providedby the invention is low in cost, is not affected by the working environment of an electronic braking system and can be used for accurately estimating the current braking force of the vehicle in orderto realize accurate braking control on the vehicle.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a braking force estimation method, device, storage medium and vehicle. Background technique [0002] An electronic braking system usually includes a brake pedal, a controller, a brake motor, an actuator, a brake pad, a brake disc, and a load cell. During the running of the vehicle, the controller determines the required braking force according to the depth of the brake pedal, controls the rotation of the brake motor according to the required braking force, and the brake motor drives the brake pads to clamp the brake disc through the actuator. , to generate the braking force for braking the vehicle. In order to achieve precise adjustment of the braking force, it is necessary to obtain the current braking force in real time during the braking process of the vehicle. The controller controls the brake motor in real time according to the required braking force and the ...
