Vehicle active roll control using roll moment rejection algorithm

摘要

In this paper, a passenger vehicle active anti-roll control was developed and simulated using a proposed anti-roll algorithm based on 14 DOF full vehicle model. The Magic Formula was used for tire model. The full vehicle model was developed and the simulation was compared with vehicle dynamics simulation software and validated using an instrumented experimental vehicle. The active roll control algorithm was then introduced to the vehicle model. Combined with PID control, the results were then simulated and analysed. From the simulation, it was found that the algorithm can significantly reduce the roll angle and roll rate of the vehicle and eventually prevent the vehicle from rollover. The improvement of the roll motion also reduced the load transfer from the inner wheels to outer wheels and hence increased the road holding during cornering.
