Abstract

The invention proposes a vehicle braking system and a control method for the vehicle braking system. By adding an emergency braking circuit on the basis of the normal braking circuit, the vehicle can be provided with the most Reliable and the most basic braking force, the emergency braking circuit controls the stage conduction by switching the solenoid valve to be de-energized and conducting, the fault guidance is safe, and the system reliability is high, so that the present invention can prevent the vehicle from completely losing the braking force, and the vehicle can be lifted braking reliability and safety.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a vehicle emergency braking system and a control method thereof. Background technique [0002] At present, most road vehicle braking systems do not have an independent emergency braking circuit, and the braking system does not recognize whether there is emergency braking. Emergency braking is a subjective expression, not a braking mode. The magnitude of the braking force of the vehicle is completely controlled by the driver, and the braking force during emergency braking is also completely controlled by the driver. The emergency braking circuit is the same as the normal braking. When the pressure source or the main pressure regulating valve fails and there is no pressure output, the vehicle will completely lose its braking ability. Or when the driver cannot continue to operate the brake operating mechanism to implement emergency braking due to his own reasons, the vehic...
