Patent ID: 8868311

Claim:
A method of controlling braking in an adaptive cruise control (ACC) of a vehicle, the vehicle having a braking system including a brake having a brake pad and a brake disc, the method comprising: determining that braking is needed, including determining an amount of braking force needed; providing an indication to the brake system that braking is needed; filling the brake system with brake fluid at a predetermined rate that is a slower rate than the brake system normally pumps the brake fluid in order to reduce pump noise; setting a delay equal to the amount of time needed to fill the brake system with fluid such that the brake system has enough fluid for the brake pad to contact the brake disc; applying the brake pad to the brake disc at the amount of braking force needed after waiting the delay; comparing the amount of braking force needed to the amount of braking force actually occurring; and reducing the delay to zero when the amount of braking force needed is less than or equal to the amount of braking force actually occurring.
