PURPOSE:To simplify the setting of a hysteresis width and obtain the setting of a required hysteresis width different in each area of throttle opening degree by adopting a construction to give the positive feedback of the output signal voltage in a comparison circuit to a resistance type potential-dividing terminal via a resistance. CONSTITUTION:A car-speed response signal EV is supplied to a control circuit as a pulse signal by a well-known means, and converted into a singal voltage VA by an FV conversion circuit. An output torque correspondence signal Etheta is formed as a potential-dividing terminal output signal V+ obtained by dividing the circuit contact- voltage by a resistance. The car-speed response signal is compared with the output torque correspondence response signal in a comparison circuit, which outputs a control signal ES for a transmission-gear-box speed-change operation control means. The positive feedback of the output signal of the comparison circuit is given to a resistance type potential dividing terminal via a resistance R, and a hysteresis width is set by changing the value of the resistance R. |
