Abstract

The invention provides a brake method and device of an automobile, a brake system and a storage medium. The brake method of the automobile comprises the steps of obtaining a current automobile speed and a current speed of a rear wheel when an emergency braking condition is satisfied; calculating the current automobile speed to obtain a first target speed and a second target speed of the rear wheel; correspondingly comparing the current speed of the rear wheel with the first target speed and the second target speed to obtain a comparison result; and on the basis of the comparison result, controlling a brake force output to the rear wheel. According to the brake method and device of the automobile, the brake system and the storage medium, the brake force applied to the rear wheel can be moreaccurate, and the brake efficiency can be enhanced.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an automobile braking method, device, braking system and storage medium. Background technique [0002] At present, when the brake system of the whole vehicle fails, the emergency braking of the rear wheels of the car mainly depends on the traditional mechanical parking structure (ie hand brake). The size is controlled by the user and often results in situations where too much or too little braking force is applied, making braking inefficient. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a braking method, device, braking system and storage medium for an automobile, so as to solve the problem of low braking efficiency during emergency braking in the prior art. [0004] The first aspect of the embodiments of the present invention provides a method for braking an automobile, including: [0005] When the emergency braki...
