Energy efficient driving

For supporting energy efficient driving, a system comprises a route information obtaining device (10), e.g., implemented by a navigation system, a monitoring device (20) and a controller (50). The route information obtaining device (10) is configured to obtain route information describing a route to be taken by a vehicle. The route information comprises speed limit information on an upcoming speed limit. The monitoring device (20) is configured to determine a current velocity of the vehicle. The controller (50) is configured to determine, depending on the speed limit information and the current velocity of the vehicle, a process for decelerating the vehicle in such a way that the vehicle can be decelerated to a target velocity, defined by the upcoming speed limit, by reducing a drive force of the vehicle.
