Problems solved by technology

[0002] Traditional vehicles are equipped with traditional vacuum boosters. The purely mechanical booster system cannot monitor the status of the vehicle from the perspective of the entire vehicle, and cannot send an alarm when the vehicle is in an under-load state, that is, the brake fluid in the brake system of the vehicle in a sealed state leaks , or air enters the brake pipeline, which will cause the brakes to be soft and in an under-load state. At this time, if the driver performs braking conditions, it will cause the driver to panic and cause driving hazards

Abstract

The invention discloses a control method of an electric power-assisted braking system. The control method comprises the following steps that of acquiring target deceleration of a vehicle; obtaining the actual deceleration of the vehicle; calculating a difference value between the target deceleration and the actual deceleration; judging whether the difference value is greater than or equal to a first preset value or not; and if the difference value is greater than or equal to the first preset value, and the electric power-assisted braking system breaks down, sending alarm information to a wholevehicle instrument so that when the vehicle is in an under-load state, a driver is warned in advance, the driver takes response measures, and driving danger is avoided. The invention further discloses a control device of the electric power-assisted braking system and the vehicle.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a control method and device for an electric power-assisted braking system and a vehicle. Background technique [0002] Traditional vehicles are equipped with traditional vacuum boosters. The purely mechanical booster system cannot monitor the status of the vehicle from the perspective of the entire vehicle, and cannot send an alarm when the vehicle is in an under-load state, that is, the brake fluid in the brake system of the vehicle in a sealed state leaks , or air enters the brake pipeline, which will cause the brake to be soft and in an under-load state. At this time, if the driver performs a braking operation, it will cause the driver to panic and cause driving danger. Contents of the invention [0003] The invention provides a control method, a device and a vehicle of an electric power-assisted braking system, so as to realize an early warnin...
