Problems solved by technology

[0003] However, the existing CDP function has many technical shortcomings
For example, in the ESP device, the CDP component is limited by the mechanical performance, and its working life is very short (usually the cumulative use time is only ten minutes or more than 100 times of activation), so frequent maintenance is required during the life cycle of the vehicle

Abstract

The invention relates to vehicle braking technology, in particular to a method for realizing controlled deceleration and braking of a vehicle, a device for implementing the method, and a computer storage medium for implementing the method. A method according to one aspect of the invention comprises the steps of: in response to a braking request from the braking parking brake system and when the controlled deceleration braking function of the electromechanical brake booster is available, the electronic stability procedure device sends the The electromechanical brake booster issues a braking command; in response to the braking command, the electromechanical brake booster responds to the opening of the automatic parking brake system control button, the duration of pulling up, and the set The parking brake force curve generates the drive signal; and uses this drive signal to drive the electric motor of the electromechanical brake booster to generate the required pressure in the master cylinder to achieve controlled deceleration of the vehicle.

Description

technical field [0001] The invention relates to vehicle braking technology, in particular to a method for realizing vehicle braking, a device for implementing the method and a computer storage medium for implementing the method. Background technique [0002] In order to ensure driving safety, vehicles are usually required to be equipped with a secondary braking system. On vehicles where the Electric Parking Brake (APB) replaces the traditional mechanical handbrake or cable, the functionality of the secondary braking system is performed by the Controlled Deceleration Braking (CDP) module. CDP is a subsidiary function of the electronic stability program (ESP) device's electronic function of the car, which can slow the vehicle to a standstill in the way requested by the driver. For vehicles equipped with the APB system, when the driver issues an emergency brake command by pulling the APB button, the CDP function of the ESP is activated. On the other hand, when the driver rele...
