<p>An electric vehicle that runs at a speed controlled by adjusting power supply to an electric motor in response to a speed setting signal from a speed setting device, including an accelerator lever and a change speed lever, comprises a first control unit 100 for producing a target speed value based on the speed setting signal, a second control unit 200 for controlling the electric motor, and a rotary encoder 90 for detecting an actual vehicle speed from rotation of the electric motor and feeding the vehicle speed back to the first and second control units. The first control unit compares the target speed value and actual vehicle speed and, when a difference therebetween exceeds a predetermined value, varies the target speed value for application to the second control unit. The second control unit compares the target speed value and actual vehicle speed and determines an amount of power supply to the electric motor. <IMAGE></p> |
