Description

Technical Field

[0001] The present invention relates to the technical field of brake systems, and in particular to a brake system control structure. Background Art

[0002] The braking system is mainly composed of four parts: energy supply structure, control structure, transmission structure and brake. The main function of the braking system is to slow down or even stop a moving car, to keep the speed of a car traveling downhill stable, and to keep a stopped car still. The control structure of the braking system is the various components that produce braking action and control the braking effect. As a key component that directly affects the driving safety of the car, the optimization and improvement of the performance of the braking system control structure has become the focus of research in the automotive industry.

[0005] However, in actual use, the above device adopts an electronically controlled mechanical brake system of the brake pedal. When the electronic brake system fails, the braking control will be lost, so other devices are needed to meet the braking needs and improve safety. In an emergency, the sudden uncontrolled braking force is not conducive to vehicle control. Since the pedal has no power assist, a larger brake pedal force is required to achieve the expected braking. In an emergency, the sudden increase in braking force will make the brake pedal force not conducive to vehicle control and also limit the upper limit of the braking force that the driver can achieve. Therefore, it is necessary to propose a braking system control structure. Summary of the invention
