PROBLEM TO BE SOLVED: To perform the stoppage of a vehicle and the warning of an error more safely when a speed sensor mounted on an electric golf car causes abnormality due to wire breaking or the like. SOLUTION: This drive controller monitors in every very short time the change of a car velocity value obtained from a speed sensor 16 and the variation of the output value of an accelerator sensor 14, according to the direction (acceleration or deceleration) of an accelerator pedal 7. In case that there is a change over a specified value in car velocity detected by the speed sensor 16 and that there is no change in car velocity for a certain time after the change, or in case that the number of times of the change gets over a specified value within a certain time, this judges it to be the fault of the speed sensor 16, and stops the vehicle and also informs the driver of occurrence of abnormality by working a warning buzzer 27.
