Summary: | A triggering module selectively generates a triggering signal when a vehicle is stopped, a grade of a surface is one of greater than a predetermined positive grade and less than a predetermined negative grade, and a brake pedal position is greater than a predetermined position. A brake actuator provides brake fluid to a braking system when the brake pedal position is greater than the predetermined position. A brake releasing module, after the triggering signal is generated, begins releasing the brake fluid from the braking system a predetermined period after the brake pedal position reaches the predetermined position. A brake applying module selectively operates a brake fluid pump after the triggering signal is generated based on a comparison of a vehicle speed and a predetermined vehicle speed. The brake fluid pump provides brake fluid to the braking system when the brake fluid pump is operated. |
