Abstract: In order to study the control strategy of hydraulic steering by wire system of electric vehicles, simulation analysis, and bench test were carried out based on AMESim. The design scheme of hydraulic steering by the wire control system for electric vehicles was proposed. The working principle, overall structure, hydraulic system design, and road sense loading system were analyzed. Based on AMESim, the simulation mathematical model of electric vehicle hydraulic steering by wire control system was established. The mathematical model of road feel, hydraulic system, actuator dynamics, and transmission ratio were described, and the PID controller with P parameter self-adaptive adjustment was designed. On this basis, the system response and anti-interference performance were analyzed, and the reliability and stability of the system in the time domain were studied. The simulation results showed that the step and sinusoidal response deviation of the system was basically less than 3° and the system had good anti-interference ability. Based on the test bench, the response and stability verification tests were carried out. The results showed that the adaptive PID controller had good responses, and under the condition of large steering, the response deviation of the system was still below 4°.
