Abstract:
1. A control apparatus for an electric vehicle including a motor that generates drive power for the electric vehicle, and a drive device that drives the motor, the control apparatus comprising: a road surface condition detection portion that detects a condition of a road surface on which the electric vehicle is driven; a slip determination portion that determines whether the electric vehicle is slipping; a torque reduction device that reduces torque of the motor when the slip determination portion determines that the electric vehicle is slipping; and a voltage control device that controls a voltage input to the drive device to reduce the voltage input to the drive device when the road surface condition detection portion determines that the road surface has a friction coefficient lower than a predetermined value, wherein the voltage input to the drive device is reduced by the voltage control device in advance of the torque reduction device reducing the torque of the motor when the slip determination portion determines that the electric vehicle is slipping.
