Abstract: Through the ana!ysis of experimenta! data , the actuator mathematical model was deduced. According to the characteristics that the actuator had the dead-zone , the control algorithm regarding the dead-zone inverse transforming compensation was designed to eliminate the adverse impact of dead-zone for control system. The effectiveness of improved algorithm was validated theoretically by MATLAB , and the corresponding control parameters were obtained. Real vehicle experiment results show that the proposed method can effective!y eliminate the control deviations caused by dead-zone.

Key words: vehicle engineering, electric power steering, dead-zone inverse transforming compensation
