Abstract

The invention relates to a braking system and a control method thereof and a vehicle, the braking system comprises a braking cylinder, a parking braking assembly, a traveling braking assembly, a pneumatic control valve and a piston, the parking braking assembly is provided with a parking connector communicating with a parking braking cavity, and the traveling braking assembly is provided with a traveling connector communicating with a traveling braking cavity; the piston divides a control cavity and a working cavity in the pneumatic control valve, the pneumatic control valve is provided with a pneumatic control connector communicated with the control cavity and the driving connector, a first connector and a second connector, the first connector and the second connector are communicated with the working cavity, the first connector is communicated with the parking connector, and the second connector is communicated with the parking braking cavity. The piston enables the first connector and the second connector to be communicated or isolated. According to the braking system, the pneumatic control valve is arranged, and the first connector and the second connector are isolated when air enters the traveling connector. The parking connector is communicated with the atmosphere, so that when the service braking cavity leaks air, compressed air in the parking braking cavity is exhausted to the atmosphere, parking braking is achieved, and the situation that a vehicle slides on a slope when service braking fails is avoided.

Description

technical field [0001] The present application relates to the technical field of vehicle braking, and in particular, to a braking system, a control method thereof, and a vehicle. Background technique [0002] At present, the application of EPB (Electrical Park Brake) system is gradually popularized. This system integrates the functions of temporary braking during driving and long-term braking after parking, and is controlled by electronic means. Implement the parking brake. Among them, the temporary braking function means that when the driver steps on the brake while the vehicle is running, the system can determine whether the vehicle is in a temporary parking state in real time, and when the vehicle is in a temporary parking state, it will automatically apply the driving braking force to the wheels. And the trigger state of the temporary braking function is fed back to the driver through the instrument, so that the driver can brake without stepping on the brake. [0003] ...
