Abstract

A vehicle has many parameters that can be measured while moving. To increase stability, these parameters need to be controlled by adjusting the torque value for each wheel. This control is often referred to as Torque Vectoring (TV). Understanding how the vehicle responds when input is given, in this case, the torque on each wheel is important in case of design a control system. Vehicle stability is indicated by the yaw rate and side slip angle value. In this study the effect of longitudinal velocity, steering angle, and correction torque on vehicle dynamics. Increasing torque correction value will increase the yaw rate and the side slip angle value linearly. Increasing steering angle will increase the yaw rate and the side slip angle linearly. As the longitudinal velocity increases, the yaw rate and the side slip angle value will increase exponentially. The side slip angle has a higher stability limit than for the yaw rate. This is means that the yaw rate stability needs more attention.
