Problems solved by technology

In the existing technology, the pressure of the brake fluid is controlled by the control system, and the brake fluid with a predetermined pressure is injected into the front end of the brake master cylinder. The brake fluid completes the braking action, but when there are multiple pistons, the multiple pistons are usually connected in series, and the motions of the pistons are coupled with each other, and the movement of the subsequent pistons will be delayed, resulting in braking delay and Inaccurate braking and other phenomena occur, affecting the user's driving experience

Abstract

The invention discloses a hydraulic brake control system, a hydraulic control method and related equipment. The system comprises an energy storage assembly, a control assembly and an execution assembly. The control assembly comprises boosters, a brake master cylinder and a brake pedal, the brake master cylinder comprises at least two piston cavities, the boosters are connected to the piston cavities respectively, and the boosters are used for controlling the pressure of the piston cavities according to the displacement of the brake pedal so as to send out a brake instruction; the execution assembly is used for executing the braking action corresponding to the control instruction sent by the control assembly. The booster is connected with each piston cavity of the brake master cylinder, the pressure of each piston cavity can be directly controlled through the displacement of the brake pedal, the execution assembly completes the braking action based on the pressure, the braking action is faster, the pistons do not move in the cavities, and complete decoupling of multi-piston movement is achieved.

Description

technical field [0001] This specification relates to the field of vehicle braking, and more specifically, the present invention relates to a hydraulic braking system, a hydraulic braking control method and related equipment. Background technique [0002] The hydraulic braking system is a commonly used braking system for current vehicles. It uses high-pressure brake fluid to pass through the brake wheel cylinder to complete the deceleration or braking of the vehicle. In the existing technology, the pressure of the brake fluid is controlled by the control system, and the brake fluid with a predetermined pressure is injected into the front end of the brake master cylinder. The brake fluid completes the braking action, but when there are multiple pistons, the multiple pistons are usually connected in series, and the motions of the pistons are coupled with each other, and the movement of the subsequent pistons will be delayed, resulting in braking delay and Inaccurate braking an...
