Abstract
A method of controlling the fluid pressure at wheel brakes of a brake system, the method comprising: (a) providing a brake system capable of delivering fluid pressure to the wheel brakes during an autonomous braking event, and wherein the brake system includes a brake pedal and sensor for sensing a driver's braking intent when applying force to the brake pedal; (b) controlling the fluid pressure at the wheel brakes at a predetermined pressure during an autonomous braking event, wherein the sensor detects no depression of the brake pedal; (c) cancelling the autonomous braking event when the sensor detects depression of the brake pedal; and (d) subsequently to step (c), the brake system enters into a handoff procedure to maintain the predetermined pressure at the wheel brakes after the sensor senses the brake pedal being depressed when a requested pressure by the driver is less than the predetermined pressure.
