All-wheel-drive electric vehicles have been widely focused, which provides the possibility for advanced control technology. In this chapter, a novel control theory for automobile will be proposed-Relaxed Static Stability (RSS), which could also lead to new overall configuration concept. The basic idea of RSS is that the lateral dynamic system of the vehicle could be designed inherent static unstable (oversteer) to improve overall configuration flexibility, and be closed-looped stable based on pole assignment with external yaw moment provided by the independent motors. In this chapter, the basic schematic control strategy of RSS is described. Finally, a nonlinear dynamic model is used to verify the performance of RSS control. The results show that the handling performance of the vehicle could be significantly improved and adjusted to satisfy different handling demand based on adjusting desired pole locations.
