Method for calculating trajectory to be followed by e.g. electric vehicle till destination, involves providing directive to driver of vehicle for indicating driver to recharge traction battery of vehicle during determined time and cost

摘要

The method involves providing a directive to a driver of a vehicle for indicating the driver to recharge a traction battery of the vehicle during determined time (TCX1) and at determined cost (CCX1) and to exchange the battery at the determined cost, and/or to add fuel in a tank of the vehicle at the determined cost. Consumption of the vehicle is estimated with respect to external information with the vehicle, where steps in the method are selected so as to minimize time to reach a destination (B) or to minimize the costs to reach the destination. The information includes weather conditions, a state of a road and traffic. An independent claim is also included for a device for calculating a trajectory to be followed by an electric or hybrid vehicle till a destination.
