METHOD AND APPARATUS FOR CARRYING OUT TRAVEL ROUTE PLANNING FOR A VEHICLE

摘要

The present invention relates to a method for carrying out travel route planning for a vehicle (1) which comprises an energy store (2) for storing the energy to drive the vehicle (1), in which method a) the destination sequence for the travel route to be planned is transmitted to a computing unit (7) which is coupled to a data memory (6) in which data relating to a route network for the vehicle (1) is stored, b) the computing unit (7) calculates a route sequence which connects the destinations of the destination sequence, characterized in that c) a forecast residual quantity of energy in the energy store (2) for traveling the route sequence is calculated, d) at least for the geographic position of the vehicle (1) at a specific destination from the destinations of the destination sequence, on the basis of the forecast residual quantity of energy in the energy store (2) of the vehicle (1) and on the basis of the stored route network and a forecast energy consumption when travelling through the route network, the points in the route network which can still be reached from a specific destination with the forecast residual quantity of energy at said specific destination are determined, and e) for at least the one destination of the destination sequence, a graphical map display is produced in which the geographic position of said destination and the points in the route network which can still be reached from said destination with the forecast residual quantity of energy of the vehicle (1) at said destination are visualized. Furthermore, the invention relates to a corresponding apparatus for carrying out said method.
