A method performs traffic-flow-conditioned adaptation of stopping processes to a synthetically modulated speed profile along a route traveled along by a vehicle. A route is selected on the basis of map data stored in a data record. The route is divided into route segments and a synthetically modulated speed profile is generated for each route segment. While the driver is travelling along at least part of the selected route, the method senses how often and for how long the vehicle stops in the route segments. The synthetically modulated speed profile is adapted for at least one route segment according to the detected stopping processes.

A method and a device determine a prediction quality for a predicted energy consumption of a motor vehicle. By determining a prediction quality, a tolerance band is calculated in addition to the predicted driving profile. The prediction quality provides a statement about the entire route as to whether a driver remains in a tolerance band that is based on stochastic evaluation and is naturally occurring. As long as the driver remains in the predicted tolerance band of the driving profile during the real drive, no re-calculation or change of the operating strategy is necessary. Fuel consumption is minimized using the predictive operating strategy on the specified distance.

In order to operate a hybrid vehicle, a mode is provided in which adjustment to the remaining electrical range is performed, specifically said remaining range is kept substantially constant. For example, the driver of the vehicle can continuously maintain the currently determined remaining electrical range by activating an activation element, in order to be able to retrieve said remaining electrical range later for purely electric driving, for example in a low emission zone. Adjustment to the remaining electrical range is more appropriate than the previously known adjustment to the charge state of the battery, because the vehicle driver can better plan his trip.
