Abstract
This paper proposes an optimization procedure of handling performance of road vehicles by using a multi-objective optimization technique that considers driver’s subjective rating for handling performance. The paper applies the procedure to examine the effects of battery location of electric vehicles on handling performance. With this procedure, Pareto solutions are first obtained with respect to four objective performance functions using constraints method. Then, the Pareto solutions are narrowed down by comparing them with the optimal domain of driver’s subjective rating. To clarify the effects of battery location on the handling performance, proposed optimization procedure is applied to the optimization of front and rear tire cornering stiffness of linear vehicle model with varying battery location. From the optimization results, following two findings are obtained: 1) the proposed procedure is useful to contract the Pareto solutions, 2) the battery location that minimizes yaw inertia is preferable from an improvement in handling performance.
