METHOD OF APPLYING AN ELECTRIC PARKING BRAKE SYSTEM IN HYBRID AND ELECTRIC VEHICLE PROPULSION SYSTEMS

摘要

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.

1. A method applying an electric park brake system of a vehicle, the method comprising:
detecting a park request with a first vehicle control module; sending a park command, from the first vehicle control module to an electric brake control module and to a second vehicle control module, to request that the electric park brake system be actuated; sending an actuation signal, from the electric brake control module to a motor winding of the electric park brake system, to actuate the motor winding, when the electric brake control module receives the park command from the first vehicle control module; sending a status actuated signal from the electric brake control module to the second vehicle control module indicating that the actuation signal, from the electric brake control module, has been sent to the motor winding to actuate the motor winding; sensing a position of the motor winding to determine if the motor winding is actuated in response to the actuation signal; and displaying a message to indicate that the electric park brake system is applied when the position of the motor winding indicates that the motor winding is actuated.
