Abstract
The yaw rate analysis is an important variable that affects the vehicle motion stability, therefore many efforts have been done to control it. The electric vehicles have some controllability advantages, due to the fact that they can use independent motors to drive the wheels, so it is not necessary to include a mechanical differential. Actually, they can use only the so-called electronic differential that can be controlled during the vehicle trip, thus many different strategies can be programmed in order to control the yaw rate. This paper present a three degree of freedom model of a four wheel vehicle implemented in Matlab to analyze the electronic differential behavior. This model uses the nonlinear Pacejka, the load transfer during curves or drive/break situations, independent steering and wheel torque, considering an in-wheel drive vehicle. The results will present different behavior of the vehicle changing some important parameters and the differential effectiveness.
