Systems and methods for controlling a backward rolling and a forward rolling on a mountain

摘要

A triggering module generates a trigger signal selectively, when a vehicle is stopped, a gradient of a surface is larger than a predetermined positive slope or less than a predetermined negative slope and a brake pedal position is greater than a predetermined position is. A brake actuator supplies a brake fluid to a brake system, when the brake pedal position is greater than the predetermined position is. A brake freely administration module begins after the generation of the trigger signal, the brake fluid a predetermined period of time thereafter, after the brake pedal position the predetermined position is reached, to release from the brake system. A brake actuation module administers a brake fluid pump according to the generation of the selectively trigger signal based on a comparison of a vehicle speed and a predetermined vehicle speed. The brake fluid pump supplies the brake fluid to the brake system, when the brake fluid pump is operated.
