A control of vehicle using steer-by-wire system with hardware-in-the-loop-simulation system

In this study, a steer-by-wire system is applied to a control vehicle. A SBW system is composed of two motors controlled by an ECU instead of mechanical linkage. Two motors follow general EPS system modeling. One motor in the steering wheel is to improve the driver´s steering feed and the other motor in the steering linkage is to improve the vehicle maneuverability and stability. Several control algorithms related with vehicle and motor can be used together. These control algorithms include understeer and oversteer gradient conception concerning the vehicle´s velocity. The SBW controller´s availability was verified through a number of simulations on the HILS system. We also have to consider the safety of the electronic system. So we can compensate for it in the software and hardware.
