An Application of Traction Vectoring to a Formula SAE Car

The Formula SAE competition is intended to encourage technical development consistent with safety. This paper describes an application of an automated “fiddle brake”, or traction vectoring system to a Formula SAE car. The expected performance advantages of the system over cars equipped with mechanical limited slip differentials is discussed. Test results are included using only a limited slip differential, the limited slip differential plus the new system, and finally the new system and an open differential. The power requirements of the system are discussed. A discussion of some other traction vectoring designs is included.
