How the four wheels should share forces in an optimum cooperative chassis control

Abstract

This paper investigates the effectiveness of weighting coefficients adaptation in simultaneous optimum distribution of lateral and longitudinal tire forces for improvement of vehicle handling and stability. Three different cases of weighting coefficients adaptation are considered in this study. Similar weighting coefficients for rear and front wheels are adopted in case (1). In case (2), the weighting coefficients of front wheels are greater than the corresponding value of rear wheels. Finally for case (3), the weighting coefficients of rear wheels are adopted to be greater than the values of front wheels. It is concluded that weighting coefficients adaptation can exert a large influence on the vehicle handling performance.
