Study on control method for semi-active suspension vehicle via magneto-rheological fluid damper based on preview

Based on the wheelbase preview control,a preview control method for MRF semi-suspension vehicle is present,and also considering the relationship between the control current and output damping force of the MRF(magneto-rheological fluid) damper.The dynamic characteristic of vehicle semi-active suspension have been investigated in different vehicle speed by computer simulation.The result demonstrates that this method improves the control performance of suspension system,reduces the shock response and vibration amplitude and improves the ride of vehicle by this method.
