Future predictor for vehicle steering guidance - sensitivity analysis and experimental results

The accessible information to the driver is important in vehicle handling problems. Under severe weather conditions, it may not be easy for the driver to steer the vehicle safely. A guidance display, which includes both the road information and the future position of the vehicle, is developed to assist the driver in handling the vehicle. The observer-based vehicle state and the driver´s steering input are used to predict the vehicle future position at a prescribed look-ahead distance. An approximation method was proposed in previous research to predict the position without integrating the vehicle dynamic equation into future time. Sensitivity analysis is performed in this paper to study the effect of the vehicle parameters on the predicted vehicle future position. Experiments are conducted to verify the approximate future predictor and the effectiveness of the guidance display
