<p><P>PROBLEM TO BE SOLVED: To provide an electric parking brake device, not long in releasing time in ordinary use time and surely releasable even when the electric parking brake is operated during travel. <P>SOLUTION: In a step S1, when the parking brake is operated, the step is shifted to a step S2 and an actuator is operated. A control part takes in a stroke value measured from a stroke sensor and stores as an operation stroke value in a storing part. In a step S3, a vehicle speed determination part determines whether the speed of a vehicle in the operation time is 0 km/h or larger than 0 km/h by a signal from a vehicle speed sensor. When it is determined that the vehicle is traveling, the step is sifted to a step S5, and the control part controls for releasing a release stroke target value for releasing the parking brake as a value of the actual operation stroke value. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
