Abstract
The invention concerns a device (1) for a motor vehicle, for avoiding an unintended complete depletion of the fuel reserves of the motor vehicle. The device is provided with a sensor (2) for determining the amount of fuel remaining in the vehicle. Further, it includes a navigation device (4), which is activated upon dropping below a minimum fuel amount and which automatically determines the actual position of the vehicle. From the position of the vehicle, the actual direction of driving and/or the road upon which the vehicle is actually located is determined. On the basis of this information, a gas station is identified in the direction or along the path of the ascertained road, and a route guidance is activated with this identified gas station as goal, and the vehicle operator is provided with appropriate driving instructions. By this procedure, it is possible to substantially prevent an unintended complete consumption of the fuel reserve even in the case that the navigation device is not initially activated.

8. A device for a motor vehicle, for avoiding an unintended complete depletion of the fuel reserves of the motor vehicle, comprising:
-
a sensor for determining the amount of fuel present in the vehicle, a navigation device, designed to determine a route to a gas station and to provide appropriate route guidance in the form of driving instructions upon dropping below a minimum fuel amount, wherein the navigation device is so controlled, that (a) in the case that the route guidance function is inactive, the position of the vehicle is ascertained, and from this the actual direction of driving and/or the road upon which the vehicle is actually located is ascertained, (b) a gas station is identified in the direction of driving and/or along the path of the ascertained road, wherein the direction from which the gas station is selected is derived from the ascertained driving direction and wherein the path of the road is derived from the ascertained road, and (c) the route guidance function is activated, with the determined position as starting point and the identified gas station as goal. - View Dependent Claims (9, 10, 11, 12, 13, 14)
