Abstract

The invention provides a brake-by-wire system for efficient and safe parking. The brake-by-wire system comprises a control valve, one end of the control valve is communicated with a power-assisted power source through a pipeline, the other end of the control valve is communicated with a brake through a pipeline, and the end, away from the control valve, of the power-assisted power source is communicated with an oil can through a pipeline. The brake-by-wire system replaces a traditional vacuum booster and a traditional parking brake, and braking of a vehicle in the driving state and the parkingstate is achieved. The brake system only comprises the brake, a hydraulic power unit, a hydraulic control system and an electrical control system, and is simple in structure, low in cost and small inoccupied space.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a high-efficiency and safe parking braking brake-by-wire system and a control method thereof. Background technique [0002] The parking brake system of a motor vehicle is mainly in the form of a mechanical parking brake handle, which is connected to the parking brake through a lever and a cable to lock the transmission shaft or the rear wheel to brake. At present, more and more cars are beginning to adopt electronically controlled parking systems, which integrate temporary braking during driving and long-term braking after parking, and realize parking braking by electronic control. . [0003] Due to vehicle space or other factors, the vehicles used in some special fields cannot use the parking brake in the form of cable type and electromechanical calipers. Contents of the invention [0004] The object of the present invention is to address the shortcomings of the abov...
