Modelling and control of complex AWD BEV architectures

Forskningsprojekt, 2021 – 2022

While a majority of electric vehicles currently have a single driven axle there is now a rapid development of new concepts for all-wheel drive (AWD) vehicles. With AWD the number of degrees of freedom to be managed increases which in turn requires more complex vehicle control to achieve high performance regarding vehicle dynamics and energy consumption. Additionally torque vectoring systems further increase the dynamic performance of the vehicles and the degrees of freedom in the controls. The proposed project will develop models on component, system and vehicle level enabling advanced simulation of different electrical AWD concepts and different use cases. This in turn enables evaluation and validation of different control strategies. A selection of the modelled concepts will also be tested and validated with data from test vehicles.
The project will contribute with valuable knowledge regarding challenges and possibilities offered by different architectures and different control strategies, as well as how well the different concepts perform in terms of vehicle dynamics and energy consumption. The results will be of value for both academic research and industrial applications.
The project budget is 1.9 MSEK.
