摘　　要：在二自由度汽车操纵动力学模型和汽车开环系统操纵性、稳定性评价指标的基础上,提出了同时考虑汽车操纵性和稳定性的加权操纵稳定性评价指标,以及考虑各种车速重要性的加权均匀操纵稳定性评价指标。应用复合形法,对汽车操纵性和稳定性进行的联合优化实例表明,利用所提出的加权均匀操纵稳定性评价指标,可以有效地实现汽车操纵性和稳定性在所有车速范围内的优化。Based on the two-dimension vehicle handling dynamics model and the evaluating indices of vehicle open-loop handling and stability,the weighted evaluating index of handling and stability which vehicle handling and stability are simultaneously considered and the weighted even evaluating index of vehicle handling and stability which importance of different speeds is considered are presented.The instance of joint optimization of vehicle handling and stability with the complex method indicates that the vehicle handling and stability can be effectively optimized in the full range of speeds with the presented weighted even evaluating index of handling and stability.
