The centrifugal force causes the vehicle body to tilt. Therefore, the load on both sides of the wheel will change. The load change value is a nonlinear function depending on the values of the fixed parameters (mass, dimension) and the change of the input values (velocity, steering angle). The increased load change value means that the vehicle is unstable. If this value approaches the limit value, the vehicle is in danger of being rollovered. The study focused on modeling and simulating the change of load distribution at different velocity and height values. The results show that when the velocity or height increases, the load on both sides of the wheel will be more different, thereby increasing the risk of instability. Some electronic control systems can be used to support vehicle stability and balance when moving.
