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. In such a constant speed driving device, a road surface inclination angle sensor detects the slope angle of the road surface on which the vehicle runs, and the characteristics of the shift diagram for constant speed driving are determined based on the sensor signal from this road surface slope angle sensor. A constant speed traveling device characterized by comprising: means for varying the speed according to the inclination of a road surface.
