Abstract
A control apparatus of an electric vehicle for effectively limiting the operation of the vehicle when it is determined that a driver of the electric vehicle is not sitting in the seat and an accelerator opening of the electric vehicle is in a position corresponding to a minimum value. A motor driving enablement circuit generates a motor driving command which selectively limits operation of the electric vehicle in accordance with these determinations. In addition, when a state in which the driver is not occupying the seat continues for a period of time exceeding a predetermined value, a motor halt controller issues a motor halt command for halting a motor of the electric vehicle. Based on the motor driving enablement command and the motor halt command, a power supply controller controls the supply of power to the motor of the electric vehicle.
