Claims

[Scope of utility model registration request]

an actual vehicle speed detection unit that detects the actual vehicle speed of the vehicle, and stores the acceleration when the vehicle is accelerated;
The vehicle includes a storage unit that stores the actual vehicle speed at the time when the vehicle speed setting switch is operated as a set vehicle speed, and a control unit, and controls the vehicle with the acceleration so that the difference between the actual vehicle speed and the set vehicle speed becomes zero. An automatic constant speed driving device that performs constant speed driving control is provided with a low fuel consumption driving mode selection switch and a normal fuel consumption driving mode selection switch, and when the low fuel consumption driving mode selection switch is closed, the control section selects each of the following. Acceleration control of the vehicle is performed along a characteristic curve of the engine speed that minimizes the fuel consumption rate with respect to the throttle opening,
Further, when the normal fuel efficiency driving mode selection switch is closed, the automatic constant speed driving device controls the acceleration of the vehicle along a characteristic curve of engine speed in a steady state on a flat road with respect to each throttle opening. .
