Abstract
PURPOSE:To perform control for good constant-speed running without hunting, by keeping the rate of increase and decrease in the driving torque of a vehicle constant independently of the transmission ratio. CONSTITUTION:A rotational angle sensor 41 for detecting the revolution speed of a crankshaft is attached to a distributor 40. A vehicle speed sensor 44 is attached to a transmission 42. The sensor 41, 44 are connected to an electronical control unit 13. When the difference between the actual speed and a set speed is constant, the degree of opening of a throttle valve is heightened as the transmission 42 is put in a higher-speed gear position. The velocity of opening of the throttle valve is decreased as the transmission 42 is put in a lower-speed position. As a result, the rate of increase in driving torque does not rise even if the transmission 42 is in a low-speed position. For that reason, hunting is avoided.
