Abstract
Systems and methods are described for distributed electric park brake control. The vehicle's electronic stability controller (ESC) is configured to monitor the status of an electric parking brake switch and to provide control signals to a motor-on-caliper actuator based on the status of the electric parking brake switch. A secondary brake system controller (for example, a brake pedal “booster” unit) that is configured to control at least one function of the braking system that is not related to the parking brake function is further configured to determine whether the ESC is operating properly and, in response to determining that the ESC is not operating properly, to monitor the status of the electric parking brake switch and provide the control signals to the motor-on-caliper actuator based on the status of the electric parking brake switch.
