Optimization of Look-ahead-Distance for a Vision-Based Vehicle

One of the features of the lateral control of vision-based vehicles is a preview characteristic for a lane along which a vehicle drives, and the look-ahead distance of the vision system affects the lateral control performance. This paper proposes optimal design of the look-ahead-distance for the lateral control performance and ride quality, when the control algorithm is designed with the linear-quadratic (LQ) regulator problem, where a vehicle drives along a straight line. The optimal look-ahead-distance becomes longer as the vehicle speed becomes higher. The computer simulation results show that the optimal look-ahead-distance found when a vehicle drives along a straight line is also feasible when a vehicle drives along a circle or a curved line.
