PROBLEM TO BE SOLVED: To dispense with an expensive current sensor for detecting a plugging running state, reduce cost and space, and enable controlling of satisfactory in feeling, in the control equipment of a motor for running. SOLUTION: A torque target value is obtained on the basis of accelerating input (step #2), a motor current is obtained (#4) from FET on-voltage input (#3). Whether a power running state or a plugging state is judged from potential difference between both ends of a plugging diode (#5), present torque is obtained on the basis of an TFT current corresponding to the power running state and the plugging state, and a specified duty target value is obtained (#6, #7). According to the duty target value and indicating duty, and the torque target value and the present torque, the indicating duty is changed (#9, #11, #12, #14). Thus, a plugging running state can be detected without requiring an expensive current sensor, and present torque can be obtained. |
