Patent number: 7234785Abstract: A parking braking system for a vehicle uses an electronic braking system (EBS) as a primary source for generating a parking brake force via pneumatic brake actuators. Each pneumatic actuator actuates a piston that is adapted to rotate a pivoted lever, which moves to apply brake pads against a brake disc. The parking braking system includes a hand control that controls actuation of the pneumatic brake actuators. Vehicle brakes for non-parking braking purposes are controlled by electronic signals generated in response to a driver's foot-generated braking demand. An electronic controller is adapted to control a supply of pressurized air to the pneumatic brake actuators in accordance with the driver's braking demand.Type: GrantFiled: March 26, 1999Date of Patent: June 26, 2007Assignee: ArvinMeritor, Inc.Inventors: Denis John McCann, Andrew John Ward
