A hill hold decay (HDD) system of a vehicle. The system includes a longitudinal acceleration sensor, a wheel speed sensor, a brake pedal detector, a gas pedal detector, a gear sensor, and a controller. The controller is configured to determine the vehicle has come to a standstill, determine a slope of the ground the vehicle is on, determine a direction of travel of the vehicle is downhill, detect a release of a brake release a brake force applied to a plurality of wheels of the vehicle at a constant first rate, determine a speed of the vehicle has reached a minimum threshold, release the brake force at a second rate as long as the speed of the vehicle is increasing, determine the speed of the vehicle has reached a maximum threshold, and release the brake force.
