Abstract:
A method applying an electric park brake system of a vehicle includes detecting a park request with a first vehicle control module, and sending a park command, from the first vehicle control module, to both an electric brake control module and a second vehicle control module. Upon the electric brake control module receiving the park command, an actuation signal is sent from the electric brake control module to a motor winding of the electric park brake system. A status actuated signal is sent from the electric brake control module to the second vehicle control module. The status actuated signal indicates that the actuation signal has been sent from the electric brake control module. A position of the motor winding is sensed to determine if the motor winding is actuated. When the motor winding is actuated, a message is displayed to indicate that the electric park brake system is applied.
