Braking system, vehicle and braking method

Abstract

The invention is suitable for the technical field of vehicle braking, and discloses a braking system, a vehicle and a braking method. The braking system comprises a wheel cylinder piston, a parking locking assembly connected with the wheel cylinder piston and a hydraulic control assembly connected with the locking assembly, and the parking locking assembly comprises a locking rod and a limiting piece connected with the locking rod and used for limiting the wheel cylinder piston; the hydraulic control assembly comprises a control rotating shaft capable of being connected with and separated from the locking rod and a hydraulic driving structure used for controlling the control rotating shaft to rotate. The vehicle is provided with the braking system. The braking method adopts the braking system and comprises a parking braking step and a parking braking releasing step. According to the braking system, the vehicle and the braking method, the adopted braking system is simple in structure and low in cost, an EPB module and a mechanical hand brake can be omitted, a gearbox P-gear parking module does not need to be additionally arranged, the weight and occupied space of the braking system are small, and the cost of the braking system is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle braking, and in particular relates to a braking system, a vehicle and a braking method. Background technique [0002] At present, EVP (Electric Vacuun Pump, electric vacuum pump) braking system and electronic hydraulic braking system are commonly used in automobile braking systems. The technology of EVP braking system is relatively mature and the cost is low, but the comfort of the braking process is poor. The system has good braking comfort and can cooperate with various comfort and safety control modules. It has gradually replaced the EVP braking system. [0003] However, the electronic hydraulic braking system generally requires an additional mechanical hand brake or EPB (Electrical Park Brake, electronic parking) module to realize the parking braking function, which is costly and will occupy additional vehicle space for layout. And due to the restrictions of regulations, the braking system us...

Problems solved by technology

[0002] At present, EVP (Electric Vacuun Pump, electric vacuum pump) braking system and electronic hydraulic braking system are commonly used in automobile braking systems. The technology of EVP braking system is relatively mature and the cost is low, but the comfort of the braking process is poor. The system has good braking comfort and can cooperate with various comfort and safety control modules, which has gradually replaced the EVP braking system

[0003] However, the electronic hydraulic brake system generally requires an additional mechanical hand brake or EPB (Electrical Park Brake, electronic parking) module to realize the parking brake function, which is costly and will occupy additional vehicle space for layout.

And due to the restrictions of laws and regulations, the braking system using the EPB module must also have the P-block parking module of the gearbox, resulting in increased weight and occupied space, and increased costs
