A method and a device for providing an electronic appointment scheduler for a vehicle. Appointments are acquired that have associated time data and geographical positions; the residual amount of energy available for driving the vehicle is acquired and data relating to a geographical road network, including the geographical positions of energy-supply devices suitable for said vehicle, are acquired. Taking into account the time data and geographical positions associated with the appointments, the available residual energy amount, and the energy consumption of the vehicle on a potential travel route, a route plan and an energy fill-up plan are produced, with supplemental periods of time being calculated that are associated with the appointments and derived on the basis of the route plan and energy fill-up plan. An appointment schedule is then produced and issued which comprises these appointments as well as the supplemental time periods that are associated with these appointments.

Method and device for providing an electronic appointment scheduler for a vehicle

A method and device for carrying out travel route planning for a vehicle, in which schedule data are transmitted to a calculation unit, which is coupled to a data memory, in which data relating to a path network for the vehicle and data relating to the geographic positions of energy supply facilities are stored. The calculation unit checks if a route sequence which connects the geographic positions of the destinations associated with the schedule data is calculable such that the destinations are reached at the associated time data of the schedule data, wherein the prognosticated residual energy amount in the energy store of the vehicle for travelling the route sequence is determined and taken into account, if no such route sequence is calculable using the calculation unit, the latter determines matched schedule data for which such a route sequence is calculable, and the matched schedule data are output.

Method and device for carrying out travel route planning for a vehicle

A method for planning a travel route for a vehicle including an energy storage unit includes a) transmitting a destination sequence to an arithmetic logic unit coupled to a data memory storing data concerning a road network, b) calculating a route sequence for the destination sequence, c) calculating a projected amount of energy remaining in the energy storage unit for the route sequence, d) ascertaining, at least for one destination in the destination sequence, based on the projected amount of energy remaining, the road network and a projected energy consumption, points in the road network still reachable from this destination with the projected amount of energy remaining, and e) generating, for at least the one destination, a graphic map depiction in which this destination and the points in the road network still reachable from this destination are visually represented. A corresponding device for carrying out the method is also described.
