An ECU closes a second relay and third relay while opening a first relay so that a drive motor and a variable resistor are connected in series, when it is determined based on detected accelerator opening &thetas;acc and vehicle speed Vc that a requirement for applying the brake on the vehicle has been made. The drive motor is driven by an external force which is input via wheels of the vehicle, thus operating as a power generation braking device. The ECU sets a variable resistance value Vc based on the accelerator opening &thetas;acc and the vehicle speed Vc. Thus, the electric power generated by the drive motor is consumed via an inverter by the variable resistor whose resistance value Rv has been set to a certain value. Accordingly, the amount of load to be applied on a mechanical braking system of a motor-driven vehicle can be reduced and an improved drivability in decelerating the vehicle can be achieved. <IMAGE>
