Brake system of automobile, automobile and control method of brake system

Abstract

The invention provides a brake system of an automobile, the automobile and a control method of the brake system so as to improve the redundancy performance of the brake system. The scheme of the invention is suitable for intelligent automobiles, new energy automobiles or traditional automobiles and the like. Specifically, the scheme of the invention relates to the improvement of the brake system in the automobile. According to the brake system, a first control valve 130 is connected with a first brake pipeline 111 and a second brake pipeline 121, so that when the first control valve 130 is ina conducting state, the first brake pipeline 111 is communicated with the second brake pipeline 121, brake fluid between the two brake pipelines can circulate, and the redundancy performance of the brake system can be improved. The situation that in an existing braking system, the first brake pipeline 111 and the second brake pipeline 121 are two independent brake pipelines, and after a pressure providing device (a pressurizing device and a braking main cylinder) on one brake pipeline fails, the automobile loses half of braking force is avoided.

Description

technical field [0001] The present application relates to the field of automobiles, and more specifically, to a braking system of an automobile, a control method of the automobile and the braking system. Background technique [0002] The braking system of a car is a system that applies a certain braking force to the wheels of the car to perform a certain degree of mandatory braking. The function of the braking system is to make the driving car decelerate or even stop forcibly according to the requirements of the driver or the controller, or to make the stopped car stably park under various road conditions (for example, on a slope), or to make the The speed of the car traveling downhill remains steady. With the development of automobile electrification and intelligence, automobiles have higher and higher requirements for braking systems. For example, with the improvement of the level of automatic driving, the dependence of the operation of the braking system on the driver i...

Problems solved by technology

However, in the above-mentioned electro-hydraulic braking system, when the pressure supply device (boosting device and brake master cylinder) on one of the brake lines fails, the car will lose half of its braking force, which cannot meet the requirements of the current automatic driving control system. Requirements for redundant performance of the dynamic system
