とする定速走行装置。 A shift diagram for constant speed driving is provided for defining a gear position to be established in a transmission according to a throttle opening of a throttle valve in an internal combustion engine and a vehicle speed during constant speed driving control of an automobile, Based on this shift diagram for constant speed driving, the throttle opening is controlled to maintain the vehicle speed at the target vehicle speed by switching the gear position of the transmission according to the actually detected actual vehicle speed value and throttle opening. The constant speed traveling device is characterized in that it comprises means for varying the characteristics of the shift diagram for constant speed traveling according to the acceleration of the automobile and the amount of change in this acceleration. Speed running device.
