Distributed braking system with manpower failure backup and pressure adjusting control method therefore

Abstract

The invention provides a distributed braking system with manpower failure backup and a pressure adjusting control method therefore, and belongs to the technical field of automobile braking systems. The distributed braking system specifically comprises a brake pedal, a human cylinder, a brake controller and a power supply, and further comprises at least three electric cylinders and solenoid valveswhich are electrically connected with the brake controller, wherein the electric cylinders are connected with a liquid discharge hole of the human cylinder through a brake pipeline, the electric cylinders are connected to the same number of wheel brakes on an automobile in a one-to-one correspondence mode, and each electric cylinder and the corresponding one wheel brake form a braking circuit; thetwo wheel brakes at the two ends of the same shaft communicates through the brake pipeline, the brake pipeline is provided with the solenoid valves, and the solenoid valves are electrically connectedwith the brake controller. The distributed braking system has the dual functions of manpower failure backup and shaft pressure equalization function, so that the intelligent driving automobile is good in motion stability and high in reliability during braking.

Description

technical field [0001] The invention relates to the technical field of automobile brake systems, in particular to a distributed brake system with manpower failure backup and a pressure regulation control method. Background technique [0002] Automobile braking system is closely related to automobile driving safety. In the hydraulic braking system of traditional automobiles, the driver applies braking pressure to the wheel cylinders of each wheel brake by depressing the brake pedal, so as to achieve braking and decelerate the vehicle. Smart car systems such as advanced driver assistance systems (ADAS) and automated driving systems (ADS) require braking systems that can autonomously brake the vehicle, that is, apply the brakes to some or all of the wheels without depressing the brake pedal. At present, most of the brake systems that can implement autonomous braking use electric power assist, and retain brake control devices such as brake pedals. With the development of unman...
