To solve the problem that front wheel control of vehicle steer-by-wire( SBW) system has high control precision and is difficult based on model, we studed the SBW front wheel system based on the hardware-in-the-loop test bench. Under the guidance of the controller development of ideas V model, we first set up the mathematical mod-el of the front wheel system using LabVIEW System Identification Toolkit. Then we designed the least sample time none-wave adaptive system. The control system was carried out by off-line simulation and hardware-in-the-loop test. The results show that the front wheel motor has fast response, almost no overshoot, and the time for system sta-ble is short. Both rapidity and follow-up can satisfy the requirement of the steering motor control. The research of Steer-by-Wire Front Wheel System controller can effectively solve the contradiction between speed and overshoot, and achieves better control effects.
