<P>PROBLEM TO BE SOLVED: To provide an electric parking brake device generating stable braking force with a simple constitution. <P>SOLUTION: The electric parking brake device 1 is provided with an electric parking brake 4 for imparting braking force to a wheel 3 using a motor 2 as a power source, a driving circuit 5 for supplying driving power to the motor 2, and a control device 7 for controlling the driving circuit 5. The driving circuit 5 supplies a constant predetermined voltage V1 to the motor 2, to be controlled by controlling it by the control device 7. Further, the control device 7 stops supplying power to the motor 2 at the time of parking braking, when a current value I to be supplied to the motor 2 becomes a predetermined current value Ix. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
