Abstract:
A control device for an electric vehicle stopping at a slope road comprising:an electric motor for driving a wheel; a drive torque control means for controlling a drive torque of the electric motor in accordance with a driving condition of the vehicle and outputting the drive torque to the electric motor; a hydraulic brake force adjusting means for adjusting a hydraulic brake force for applying a hydraulic pressure to a wheel cylinder of the wheel independent from a brake pedal operation; a judging means for a stopping state at a slope road which judges whether the vehicle is under a stopping state at a slope road when the drive torque is equal to or greater than the predetermined value; wherein when the judging means for the stopping state at the slope road judges that the vehicle is under the stopping state at the slope road, the hydraulic brake force adjusting means applies a predetermined hydraulic pressure to the wheel cylinder of the wheel and the drive torque control means decreases a drive torque outputted to the electric motor to be lower than a drive torque controlled in accordance with a driving condition of the vehicle.
