The steering resistance torque of the vehicle on low-adhesive road is greatly reduced, so using traditional EPS control strategy may result in the driver's road feeling being reduced or even lost, endangering driving safety. In this paper, the variation of steering resistance torque of different adhesion coefficient roads is analyzed. And two new EPS control strategies of commercial vehicles considering adhesion coefficient based on steering resistance torque and compensation current are designed. Finally, a joint simulation model of TruckSim/Simulink is established, the two control strategies are simulated and verified. The simulation results show that both the two control strategies can improve the road feel of the driver and improve the driving safety on the low-adhesion road while ensuring the steering portability.
