ABSTRACT
In recent years, the auto industries have produced the lane keeping assistance systems for preventing lane departure due to driver’s distractions or drowsiness. In order to avoid the driver’s wrist injury by the control effort, these LKA systems limit the output values of the steering-wheel assist torque. This limiting mechanism, however, can cause a problem when the driver – especially a novice driver – cannot follow a road curvature, because a significant amount of control effort can be exerted on the driver’s wrist. To solve this problem of the existing LKA systems, this paper proposes a new LKA system based on preview AFS/BTV integrated control. To investigate the performance of the new LKA algorithm proposed in this paper, simulation has been carried out on various driving test conditions.
