Patent ID: 8668279

Claim:
A system for controlling an electronically actuated brake, the system comprising: a brake actuation system; a brake pedal; an electronic brake control unit configured to operate in a normal mode and a parking brake mode, the electronic brake control unit connected to receive a signal from the brake pedal when the brake pedal is depressed; a non-volatile latch module connected to receive an output from the electronic brake control unit and output to the electronic brake control unit; and a momentary switch contact connected to output to the electronic brake control unit and to the non-volatile latch module; the electronic brake control unit further configured to operate in the parking brake mode when the brake pedal is deflected at or beyond a threshold deflection and the momentary switch contact is engaged, such that when changed to the parking brake mode the electronic brake control unit outputs a signal to the non-volatile latch mechanism and receives one of an on and an off signal from the non-volatile latch mechanism and the electronic brake control unit communicates with the electronically actuated brake to change its state between on and off, and a present state of the electronically actuated brake is saved in the non-volatile latch mechanism.
