Distributed braking system with human failure backup and pressure regulation control method

Abstract

The invention provides a distributed braking system with human failure backup and a pressure regulation control method, belonging to the technical field of automobile braking systems. It specifically includes a brake pedal, a manpower cylinder, a brake controller and a power supply, and also includes at least three electric cylinders and electromagnetic valves electrically connected to the brake controller, and the electric cylinders are respectively connected to the The drain holes of the manpower cylinders are connected, and the electric cylinders are connected to the same number of wheel brakes on the car one by one, and each of the electric cylinders forms a braking circuit with a corresponding wheel brake; the two ends of the same shaft The two wheel brakes are communicated through a brake pipeline, and a solenoid valve is arranged on the brake pipeline, and the solenoid valve is electrically connected with the brake controller. The invention has the dual functions of manpower failure backup and shaft pressure equalization function, so that the smart driving car has good motion stability and high reliability when 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...
