Abstract
Official abstract text for this publication.
A method of controlling an electronic parking brake of a vehicle having a dual clutch transmission. The method includes: identifying a slope of an area in which the vehicle is located in order to determine whether the identified slope exceeds a predetermined slope value; determining whether both of two clutches are opened in a safe mode when the identified slope exceeds the predetermined slope value; determining whether the vehicle moves upward in a front direction when both of the two clutches are opened; and operating the electronic parking brake when the vehicle moves upward in the front direction. When the vehicle moves upward in the front direction on the inclined road, the electronic parking brake is automatically operated to prevent the vehicle from slipping in the rear direction. Therefore, the method can effectively improve the safety of the driver and vehicle even when the driver is inept in pedal operation.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling an electronic parking brake of a vehicle having a dual clutch transmission, the method comprising: identifying a slope of an area in which the vehicle is located in order to determine whether the identified slope exceeds a predetermined slope value; determining whether both of two clutches are separated from a drive shaft of the vehicle due to execution of a safe mode when the identified slope exceeds the predetermined slope value; determining whether the vehicle moves forward-and-upward in a front direction when both of the two clutches are opened; and automatically operating the electronic parking brake to brake the vehicle without driver intervention when the vehicle moves forward-and-upward in the front direction in order to prevent the vehicle from slipping rearward. 2. The method of claim 1 , further comprising: determining whether a travelling speed of the vehicle exceeds a predetermined speed; and operating the electronic parking brake when the travelling speed of the vehicle exceeds the predetermined speed. 3. The method of claim 1 , further comprising: terminating an operation of the electronic parking brake when a signal for releasing an automatic control of the electronic parking brake according to an intention of a driver is transferred. 4. The method of claim 2 , further comprising: terminating an operation of the electronic parking brake when a signal for releasing an automatic control of the electronic parking brake according to an intention of a driver is transferred.
