For a vehicle (100) with an electric motor (110) that is powered from an on-board battery (120), performance indicators (150) such as the driving range (151) of the vehicle (100) and the lifetime (152) of the battery (120) are calculated by an on-board processor (160). There are many parameters (161, 162) to take into account, and parameters are available at different points in time and with sometimes unexpected occurrences. To reduce complexity and computational efforts, the solution approach divides calculations into separate calculation models (141, 142) and selects the application of models according to priorities, internal/external parameters, computational complexity etc. That allows real-time calculations after parameters become available so that the calculation results can be presented to users for making decisions: the range (151) can be presented to the driver while driving, and the battery lifetime (152) can be presented to the management of a vehicle fleet. |
