Patent ID: 7890240

Claim:
A method of implementing a brake pedal gain change in a vehicle having a brake simulator, a brake pedal operable by a driver of the vehicle for commanding actuation of a brake system, and a pedal sensor, the method comprising: detecting a fault in the brake system using a fault sensor; detecting at least one of a brake pedal force and a brake pedal travel of the brake pedal using the pedal sensor; converting the at least one of a brake pedal force and a brake pedal travel to a driver intended brake torque using the brake simulator; calculating the brake pedal gain change using the brake simulator; and applying the brake pedal gain change to automatically reduce the driver intended brake torque; wherein applying the brake pedal gain change increases a required amount of the brake pedal force needed to achieve a desired rate of vehicle deceleration, thereby providing tactile feedback to the driver of said fault in the brake system.
