Human simulated sliding mode control for vehicle collision absorbing system based on magneto-rheological absorber

The vehicle collision absorbing system based on magneto-rheological (MR) damper is proposed to cope with the problems of traditional passive vehicle absorbing system. A dynamic model of vehicle collision based on an MR absorber is first constructed. A human simulated sliding mode control (HSSMC) is then formulated according to the characteristics of vehicle collision. Finally, the numerical simulation is performed to validate the MR collision absorber and the proposed control strategy considering the uncertainties of impact initial velocities and vehicle masses. The numerical results show that the vehicle collision absorbing system with HSSMC can achieve significant reduction in the deceleration during the vehicle crash and promote passengers´ the safety. Furthermore, the HSSMC exhibits the strong robust.
