Patent ID: 6997521

Claim:
A braking system for a vehicle comprising: a plurality of ground engaging wheels attached to and supporting a vehicle body; a service braking system associated with at least one of the wheels, the service braking system adapted to actuate a brake for slowing the vehicle from a moving state to a stationary state; a parking braking system associated with at least one of the wheels, the parking braking system being separate from the service braking system, the parking braking system adapted to actuate a brake while the vehicle is stationary to hold the vehicle in a stationary position; a braking control system associated with the service braking system and the parking braking system, the braking control system including: a parking brake control adapted to produce a parking brake signal in response to an operator command to actuate the parking braking system; a speed sensor adapted to produce a vehicle speed signal; and an electronic control module (ECM) adapted to receive the parking brake signal and the vehicle speed signal; wherein when the ECM receives the parking brake signal and the vehicle speed signal indicates that the vehicle is moving at greater than a first speed, the ECM actuates the service braking system.
