Together with the tires, suspension, and other systems, the steering system is a key system determining the driving performance of an automobile. Using recent advances in electronic control technology, automobile manufacturers and related suppliers are developing a variety of next-generation steering systems. Because these new steering systems differ greatly from conventional systems in regard to the path and method of transmission of force from the steering wheel to the tires, setting the turning torque generated when the driver turns the steering wheel presents difficult technical problems which are of considerable importance. In the pioneering development of turning torque characteristics fbr these new steering systems, a combination of simulation with parameter design was used to make the development process more efficient. As a result, target turning torque characteristics were achieved in the short time of 1.5 months. Besides greatly improving the efficiency of the pioneering development phase,this study demonstrated the effectiveness and general applicability of an optimization process combining simulation with parameter design.
