The center of gravity of the vehicle is located at the point \(T\). The front and rear axles are located at the points \(F\) and \(R\), respectively. The constant \(a\) measures the distance of point \(F\) to \(T\) and \(b\) the distance of point \(T\) to \(R\). The angles \(\alpha_F\) e \(\alpha_R\) are the front and rear slip angles, respectively. \(\alpha_T\) is the vehicle side slip angle and \(\psi\) is the vehicle yaw angle. \(\delta\) is the steering angle.
