Problems solved by technology

[0004] Most of the dual-circuit autonomous braking systems at this stage use each circuit to control a wheel brake. When one of the four wheels is locked, but the other wheel is not locked or the braking force may be insufficient, the dual-circuit brake The system can only reduce the braking pressure of two wheels at the same time, resulting in unsafe braking

Abstract

The invention relates to the technical field of an autonomous braking system, and concretely provides a time-sharing autonomous braking system with a failure labor backup function and a baking method.The time-sharing autonomous braking system comprises a power supply (9) and a braking controller (10) and also comprises a first electric cylinder (8a), a second electric cylinder (8b) and a labor cylinder; the first electric cylinder (8a) and the second electric cylinder (8b) are electrically connected with the braking controller; the labor cylinder is electrically connected with the first electric cylinder (8a) and the second electric cylinder (8b); the first electric cylinder (8a) and the second electric cylinder (8b) are respectively connected to two wheel brakes arranged on an automobileto form two braking loops; an electromagnetic valve is arranged between each wheel brake and the corresponding electric cylinder. The braking method provided by the invention comprises an autonomousbraking mode, a failure labor backup braking mode and a failure protection braking mode. The time-sharing autonomous braking system has the advantages that the structure is simple; the cost is low; the braking response is fast; the reliability is high; the failure protection capability is high; the braking control and the ABS function of single wheels can be realized.

Description

technical field [0001] The invention relates to an autonomous braking system, in particular to a time-sharing autonomous braking system and a braking method with a failure manpower backup function. 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 unmanned logistics ...
