Abstract

When a shift position is shifted from an R range to a D range and when the shift position is shifted from the D range to the R range, an electrically-operated parking brake device is automatically cancelled. In this manner, the electrically-operated parking brake device is cancelled without waiting for the depression of an accelerator pedal with a driver'"'"'s intention to start a vehicle taken into consideration. Therefore, it is possible not only to alleviate a burden on the driver in canceling the electrically-operated parking brake device, but also to prevent an abrupt starting of the vehicle due to the cancellation of the electrically-operated parking brake device while the accelerator pedal is being depressed to transmit a large driving force to driven wheels.

Claims

1. An electrically-operated parking brake device adapted to actuate wheel brakes by an electrically driving mechanism, wherein when one of a forward traveling range and a backward traveling range is selected and the wheel brakes are in operation, if the one traveling range is shifted to the other traveling range, the wheel brakes are released in response to said shifting.
