Purpose and goal

This project has developed a method to estimate longitudinal vehicle velocity and road slope angle which is used to solve the case when wheels are slipping. The algorithm is successfully verified by extensive winter tests under realistic conditions and it performs well on slippery road also when all of the four wheels are slipping.

Results and expected effects

The fact that AAM has applied for a patent related to the technology developed in this project emphasizes the relevance to the company. Furthermore, both the invitation to present this work in a plenary session at a major vehicle dynamics conference and that one journal paper was accepted for publication in an international journal shows that the project has been highly relevant to the academia. Furthermore, the master´s thesis which has been another outcome of the project, was nominated as the best Master´s at Tongji University for 2013.

Approach and implementation

This project has been executed with a master thesis (exchange) student from Tongji University, Shanghai as well as senior researchers at Chalmers and e-AAM. The combination of the collaboration between Chalmers and Tongji University and e-AAM´s hybrid electric technology and winter test facilities in Arjeplog, Sweden have been key enabling factors for this project.
