Abstract
An electric parking brake system according to one embodiment comprises: a first electric parking brake provided at a front wheel of a vehicle so as to generate a first clamping force; a second electric parking brake provided at a rear wheel of the vehicle so as to generate a second clamping force; an inclination sensor for detecting the inclination degree of the vehicle; and a control unit for determining the total clamping force required for parking on the basis of the inclination degree of the vehicle and vehicle weight information, determining the electric parking brake, to be operated, from among the electric parking brakes according to the determined total clamping force, and operating the determined electric parking brake.
Claims13
An electronic parking brake system, comprising:
- a first electronic parking brake provided on a front wheel side of a vehicle to generate a first clamping force;
- a second electronic parking brake provided on a rear wheel side of the vehicle to generate a second clamping force;
- a gradient sensor detecting a gradient of the vehicle;
- and
- a controller determining a total clamping force required for parking based on a vehicle gradient and vehicle weight information, determining an electronic parking brake to operate among the electronic parking brakes according to the determined total clamping force and operating the determined electronic parking brake,
- wherein a first clamping force generated by the first electronic parking brake is set to be lower than a second clamping force generated by the second electronic parking brake,
- wherein the controller selectively determines an electronic parking brake to operate as at least one of the first electronic parking brake and the second electronic parking brake based on a comparison of the determined total clamping force with at least one of the first clamping force and the second clamping force.
An electronic parking brake system, comprising:
- a first electronic parking brake provided on a front wheel side of a large vehicle to generate a first clamping force;
- a second electronic parking brake provided on a rear wheel side of the large vehicle to generate a second clamping force set to be higher than the first clamping force;
- a gradient sensor detecting a gradient of the large vehicle;
- and
- a controller operating the first electronic parking brake while stopping the second electronic parking brake if a weight of the large vehicle is in a first weight range in a case where the detected gradient when parking is applied is in a preset range,
- stopping the first electronic parking brake while operating the second electronic parking brake if the weight of the large vehicle is in a second weight range set to be higher than the first weight range, and
- operating both the first electronic parking brake and the second electronic parking brake if the weight of the large vehicle is in a third weight range set to be higher than the second weight.
A control method of an electronic parking brake system including a first electronic parking brake provided on a front wheel side of a vehicle to generate a first clamping force and a second electronic parking brake provided on a rear wheel side of the vehicle to generate a second clamping force, the control method comprising:
- detecting a gradient of the vehicle,
- determining a total clamping force required for parking based on the detected vehicle gradient and vehicle weight information,
- determining an electronic parking brake to operate among the electronic parking brakes according to the determined total clamping force, and
- operating the determined electronic parking brake,
- wherein a first clamping force generated by the first electronic parking brake is set to be lower than a second clamping force generated by the second electronic parking brake,
- wherein the determining the electronic parking brake to operate comprises selectively determining the electronic parking brake to operate as at least one of the first electronic parking brake and the second electronic parking brake based on a comparison of the determined total clamping force with at least one of the first clamping force and the second clamping force.
