操纵稳定性、制动性及平顺性对汽车行驶安全性影响的联合评价

Cooperative Evaluation of Influence of Handling Stability,Braking and Ride Comfort on Vehicle Driving Safety

操纵稳定性、制动性和平顺性是汽车行驶安全性的重要影响因素.在讨论三项性能的国标评价法的基础上,从影响行驶安全性的角度选择评价指标参数,并给出各单项性能评价新的计分方法.考虑不同车型对各单项性能的要求侧重不同,通过设置不同的权重值,建立联合评价方法.以某车型基于ADAMS/Car的虚拟仿真试验和实车道路试验结果为参考,用新方法进行了三项性能对汽车行驶安全性影响的联合评价.

Handling stability, braking and ride conffort are important factors that influence the safely of vehicle driving. On the basis of discussion on the three performance evaluation methods adopted by GB, the evaluation index parameters were selected from the point of view of driving safety and a new scoring method for each individual performance evaluation was given. Considering different requirements of individual performance, a cooperative evaluation method was established through different weights assignment. Taking the results obtained from the virtual simulation test based on ADAMS/Car and the real ear road test as a reference, the new method was used to make a cooperative evaluation of influence of the three performances on vehicle driving safety.
