Prediction of a vehicle maximum forward speed to pass double lane change manoeuvre

Abstract: In this study, a simple method is proposed to predict the maximum speed for a vehicle to pass a double lane change (DLC) test manoeuvre. This method utilises a simple roll plane model with only four parameters to predict the vehicle centre of gravity (CG) lateral acceleration limit. Then the allowed minimum curvature radius of the vehicle CG trajectory during all possible DLC manoeuvres is maximised using an optimisation approach. The vehicle CG lateral acceleration predicted by the simplified roll plane model is compared with that predicted by a well-correlated full vehicle multi-body ADAMS model; the maximum speed passing DLC manoeuvre predicted by the proposed method is then further compared and validated with field test data from the same vehicle.
