Development of the Electronic Control Unit for the RSBW using a HILS system

摘要

The SBW system in a passenger car substitutes the typical mechanical linkage between the steering wheel and the front wheel with electric wires. The control conception of the RSBW system was proposed in this paper. Basically, the controller should compensate for a conventional steering system composed of mechanical linkages. The HILS system was developed for the ECU to control an SBW system. The HILS system is available for developing control logic before installing the ECU in a real vehicle. The prototype ECU has confirmed its suitability before applying the SBW system to the real vehicle through a number of simulations with the HILS system.
