With the continuous advancement of automotive intelligence, new energy vehicles are becoming increasingly popular. These vehicles demand a steering system independent of the engine, offering better control and enhanced steering performance. The steer by wire (SBW) system, known for its high precision and fast response, fulfills these requirements by providing improved flexibility, stability, and comfort. Consequently, SBW systems have attracted significant attention in both research and application domains. As the mechanical structure of the steer-by-wire system is canceled, the road feel can not be directly transmitted to the steering wheel, and it is necessary to apply the road feel obtained according to the state of the vehicle or combined with the planning of the driving environment to the steering wheel through the road feel motor to complete the road feel simulation so that the driver can feel the feedback similar to that of the traditional steering vehicles, which can not only increase the driver's driving experience, but also enhance the safety of the driving, so it is very important to investigate the road feel simulation of the steer-by-wire system, which is very important. Therefore, it is very important to study the road feel simulation of the steer-by-wire system. In this paper, we analyze the system components of the steer-by-wire system, establish the steering system model, and design two road feel simulation algorithms, one is based on the dynamic model of the road feel simulation algorithm, and the other is based on the parameter fitting of road feel simulation algorithm. The effects of the two road feel programs are compared through simulation tests.
