Abstract

The invention discloses an emergency braking control method achieved through an electrical park brake. Under the emergency braking condition (for example, a brake pedal is blocked), after status information applied by a park brake switch is collected through an electrical park brake (EPB) system, a command is sent to a vehicle body electrical stable system (ESP) through bus communication, four wheels are braked at the same time through the ESP according to the deceleration value required by the EPB, and if one wheel of a vehicle is locked, the ESP can initiatively execute an anti-lock program. By means of the series of movements, safe and stable braking of the vehicle can be achieved, and person safety and vehicle safety are guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of chassis electronic control braking strategy design, in particular to an emergency braking control method realized by electronic parking braking. Background technique

[0002] When the vehicle uses the traditional mechanical handbrake to achieve braking in an emergency (such as the brake pedal is stuck), because only a large braking force is applied to the rear two wheels, the rear wheels will often lock up and the vehicle will flick. greater safety hazard. Contents of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides an emergency braking method realized by electronic parking brake. The Electronic Parking Brake (EPB, Electrical Park Brake) controller controls the switch to collect emergency braking requirements, and according to the current braking system failure, commands the Electronic Stability Program (ESP) to use different braking method...
