Abstract

A route finder device for a motor vehicle contains a data input unit for inputting one or more destinations for a journey, a road network memory for storing the locations on the network of roads which can be used by the vehicle, a computer unit for determining one or more possible routes from the location to the destination or destinations including energy supply processes which may be required at one or more energy supply locations as a function of the quantity of energy present in the energy accumulator, the energy supply network and the route specific energy consumption, as well as a display unit for displaying the routes determined by the computer unit. When used in electric vehicles, this device permits optimum routes to be found, taking into account charging processes for the traction battery.
