Abstract

The invention provides a vehicle braking system and a vehicle braking system control method, an emergency braking loop is additionally arranged on the basis of the common braking loop, and therefore when the common braking loop of the vehicle fails, the most reliable and most basic braking force can be provided for the vehicle; the emergency braking loop controls stage conduction by switching power-off conduction of the electromagnetic valve, fault guiding is safe, the system reliability is high, the situation that the braking force of the vehicle is completely lost can be prevented, and the braking reliability and safety of the vehicle are improved.

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...
