To prevent electric power from being consumed in vian, and prevent sensors from being damaged and the like when an abnormal value is detected by the sensors.
The auxiliary motive power control device 10 is equipped with a driving circuit 16 feeding the electric power of a battery 14 to a running motor 12, a footing force sensor 18 detecting the footing force F1 of a pedal, a vehicle speed sensor 20 detecting a vehicle speed (v), a control circuit 22 controlling the driving circuit 16 based on the footing force F detected by the footing force sensor 18 and the vehicle speed (v) detected by the vehicle speed sensor 20, and with a power supply switch 24 for the footing force sensor 18 and the vehicle speed sensor 20. And when the footing force F1 detected by the footing sensor 18 or the vehicle speed (v) detected by the vehicle speed sensor 20 is abnormal, the control circuit 20 functionally opens the power supply switch 24.
