Abstract
Provided is an electronic parking brake system including: an electronic parking brake configured to provide a clamping force required for parking a vehicle by a motor; and a controller electrically connected to the motor, wherein the controller is configured to, in response to the electronic parking brake being in a parking release state or in a parking stop state and a transmission position being in a P-stage, identify whether a rollback occurs in the vehicle, and upon determining that a rollback has occurred in the vehicle, operate the electronic parking brake to park the vehicle.
Claims15
An electronic parking brake system comprising:
- an electronic parking brake configured to provide a vehicle with a clamping force required for parking by a motor;
- and
- a controller electrically connected to the motor,
- wherein the controller is configured to, in response to the electronic parking brake being in a parking release state or in a parking stop state and a transmission position being in a P-stage, identify whether a rollback of the vehicle occurs, and in response to identifying that a rollback of the vehicle has occurred, operate the electronic parking brake to park the vehicle,
- wherein the controller is further configured to identify whether a rollback of the vehicle occurs based on at least one of a vehicle speed, a wheel speed, or a longitudinal acceleration of the vehicle.
A method of controlling an electronic parking brake system including an electronic parking brake configured to provide a vehicle with a clamping force required for parking by a motor, the method comprising:
- identifying whether the electronic parking brake is in a parking release state or in a parking stop state and a transmission position is in a P-stage;
- in response to identifying that the electronic parking brake is in a parking release state or in a parking stop state and the transmission position is in a P-stage, identifying whether a rollback of the vehicle occurs;
- and
- in response to identifying that a rollback of the vehicle has occurred, operating the electronic parking brake to park the vehicle,
- wherein the identifying of whether a rollback of the vehicle occurs includes identify whether a rollback of the vehicle occurs based on at least one of a vehicle speed, a wheel speed, or a longitudinal acceleration of the vehicle.
