Title:
ELECTRIC PARKING BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2006131151
Kind Code:
A
Abstract:

To provide an electric parking brake device capable of rapidly suppressing the shortage of the braking force when the shortage is detected while applying an electric parking brake.

If the movement of a vehicle is detected (if the determination in S30 is YES) while an electric parking brake is applied (after S25-S29 are implemented if the determination in S23 is YES), or if a parking switch is operated by a driver (if the determination in S31 is YES), the application force is increased by the preset value ΔF (S32). The application force can be rapidly increased in comparison with a case in which the increase of the application force is obtained by the operation to increase the application force, and the shortage of the braking force can be suppressed. Further, since the table to be used when determining the target value of the application force is corrected (S33), occurrence of the shortage of the braking force can be avoided in the subsequent cases.
