Abstract

The invention relates to the technical field of vehicle braking control systems or components thereof, in particular to a distributed braking system with multiple working modes and a parking function.The distributed braking system comprises a braking pedal, a manpower cylinder, a braking controller and a power supply, and further comprises at least three electric cylinders electrically connectedwith the braking controller; the electric cylinders are correspondingly connected to wheel brakes with the same number on a vehicle one to one; each electric cylinder and the corresponding wheel brakeform a braking loop; and each electric cylinder comprises a shell, a motor connected with the shell, a cylinder body, and a piston part slidingly arranged in the cylinder body. The distributed braking system is characterized by further comprising a disc part and a connecting rod; one end of the connecting rod is hinged with the piston part; and the other end of the connecting rod is eccentricallyand rotationally connected with the disc part. The distributed braking system has such advantages as compact structure, fast braking response, capability of realizing the parking function, reliable failure protection capacity and low manufacturing cost, and is high in vehicle braking reliability.

Description

technical field [0001] The invention relates to the technical field of vehicle braking control systems, in particular to a distributed braking system with multiple working modes, capable of realizing braking in a short time and having a parking function, and a braking pressure vector control method thereof. 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 po...
