Abstract :
Automobile Steering by Wire (SBW) system is an advanced steering system, which cuts off the mechanical connection between steering wheel and steered wheels. It controls the steering motor to steer front wheels actively so as to improve handling and stabilities and active safety, and controls steering wheel motor to supply the driver with ideal road feel. Driver-vehicle-road closed loop models of SBW are built based on Matlab/Simulink software platform, including steering wheel assembly and driver model. Model parameters are optimized using genetic algorithm. Real car test proves that the model fits experiments well.
