Research on Key Issues of Consistency Analysis of Vehicle Steering Characteristics

Abstract Given the global lack of effective analysis methods for impact design parameter tolerance on performance deviation in vehicle proof-of-concept stage, it is difficult to decompose tolerance. This study proposes a set consistency steering performance. The process and control automotive conceptual phase proposed first time. A dynamics model constructed, multi-objective optimization software Isight used optimize car. Sensitivity value. interval obtained by comparing original car value with optimized With help layer-by-layer decomposition theory mathematics, has been decomposed into Through simulation real experiments, validity method presented this paper are verified. from can be achieved at stage.
