With an increasing market of electrified vehicles, the question on usage-dependent optimal drive train occurs. This drive train can strongly differ from the one of conventional vehicles.

Problem

The challange is the huge amount of combinations and possible dimensionings of the drive train, of which the best has to be found. This optimum can have technical or economical goals. This study focuses on a minimization of the energy consumption, which normally influences all other command variables positively.

Goal

With simulations and optimizations and the input of boundary conditions (vehicle class, speed, acceleration, ...) the drive train consisting of electric machine, transmission, wheels and battery should be dimensioned together with technical characteristics of the vehicle.

Approach

• Derivation of a well-suited optimitation strategy
• Set up of a vehicle model with validated scalable component models
• Generalized analysis and interpretation of the results
