Abstract:
the control device for electric vehicle in the first embodiment, in the electric vehicle including the motor that functions as the traveling driving source and provides a regenerative braking force to the vehicle, and the friction brakes that provide the friction braking force to the vehicle, detects the motor rotation speed proportionate to a running speed of this electric vehicle, estimates the disturbance torque that acts on the motor, and performs the control such that the motor torque command value converges to the disturbance torque estimated value as the motor rotation speed decreases. Then, when the motor rotation speed becomes almost 0, the control device performs the control such that the friction-braking-amount command value with respect to the friction brakes converges to a value determined on the basis of the disturbance torque estimated value, and causes the motor torque command value to converge to almost 0.

Claim (Index 24):
A control device for electric vehicle including a motor that functions as a traveling driving source and provides a regenerative braking force to a vehicle, and a friction braking portion that provides a friction braking force to the vehicle, the control device comprising:\n a speed parameter detector configured to detect a speed parameter proportionate to a running speed of the electric vehicle; a disturbance torque estimator configured to estimate a disturbance torque that acts on the motor; a friction-braking-amount controller configured to control a friction braking amount of the friction braking portion; and a motor torque controller configured to control a torque of the motor, wherein when the speed parameter becomes almost 0, and the vehicle is determined to be in a vehicle stop state, the friction-braking-amount controller causes the friction braking amount to electrically converge to a value determined on the basis of an estimated value of the disturbance torque, and the motor torque controller causes the motor torque to converge to almost 0.
