Abstract
A fuel-saving driving system which gradually decreases a target vehicle speed from a start of control to passage of a descending-slope starting point in a linear form and can obtain fuel-saving and smooth driving feeling without repeating fuel-cut and injection. A vehicle-position specifying device is provided for specifying the position of a vehicle, a storage device for storing data of a descending slope located in the vehicle traveling direction, a vehicle speed measuring device for measuring a speed of the vehicle, and a controller The controller has a function of determining a target speed of the vehicle from the vehicle speed and the data of the descending slope.
