Abstract

Abstract: With consideration of the characteristics of Electric Power Steering system (EPS), vehicle lane keeping system can make full use of EPS function as steering actuator for lane following assist. A couple of vehicle dynamic equations were derived for two operational modes including steering assistant mode and active steering mode. Meanwhile, vehicle single track handling model, nonlinear tire model, driver model, EPS model and corresponding optimal lane tracking algorithm were built and developed respectively. The lane keeping algorithm with EPS actuator was validated by virtue driver-in-the-loop approach based on the EPS experimental map from a certain type of production vehicle. It has been shown that the lane keeping system with EPS assist can effectively improve the capability of tracking the desired path.
