摘要
为了对最速操纵的汽车进行操纵稳定性评价,在考虑驾驶员忙碌程度、侧翻、侧滑评价指标的基础上,增加行驶速度单项评价指标、附着性能单项评价指标,提出了汽车最速操纵的综合评价指标;基于ADAMS/Car,对汽车进行双移线仿真试验,获得了汽车最速操纵的综合评价指标和单项评价指标仿真结果,比较了不同初始车速下汽车最速操纵的综合评价指标数值。结果表明,单项评价指标和综合评价指标都随时间延长而增大,当初始车速提高时,最速操纵稳定性综合评价指标增大,操纵稳定性变差。
To evaluate the vehicle minimum time handling and stability,a comprehensive evaluation index of vehicle minimum time handling was proposed by adding the single factor evaluation index of speed and adhesion performance,considering the evaluation index of driver＇s busy,roll,sideslip.The double lane change test for vehicle was simulated with ADAMS/Car.The simulation results for the index values of single factor evaluation and comprehensive evaluation of vehicle minimum time handling were achieved.Moreover,the comprehensive evaluation index values of the handling and stability were compared under different initial speeds of the vehicle to complete double lane change test.The results show that both of the index values of single factor evaluation and comprehensive evaluation increase with time.The comprehensive evaluation index value of the minimum time handling and stability increases with the initial speed increasing,and the handling and stability are weakened.
