Abstract
The haptic guidance steering control is a driver assist system to supply small torque to the steering wheel to follow the target trajectory, which is calculated based on the PD control with the feedback of the error between the target trajectory and the look-ahead position. The change of the look-ahead position according to the radius of the curve is measured and the performance of the haptic guidance control considering the change of the look ahead position is examined through the driving simulator experiments. The results indicated the adjusting the look-ahead position improves the stability of the vehicle.
