| Abstract: | Vehicle's steady state cornering performance (oversteer / understeer) has substantial influence on its handling and stability. Main factors affecting this performance are analyzed based on modeling of coach HFF6850 for simulation of the handling dynamics by ADAM. The steady state cornering performance is appraised by scoring of three indicatives, i.e. lateral acceleration at neutral steering point, understeer rate, and roll rate of the vehicle body, and then comprehensive scores are calculated. Suspension and tire parameters are adjusted according to the comprehensive scores to improve the coach's handling performance. |
