为了提高安全距离模型计算的精确性与合理性.运用综合加权的方法分析了驾驶员状态、车况以及自然环境与路况因素对安全车距模型参数的影响.通过不同行驶工况下的仿真以及实车实验验证了提出的安全车距修正模型对不同驾驶员状态、车况以及自然环境与路况的适应性.分析说明了自然环境与路况以及车况的差异既影响报警安全车距也影响极限安全车距,驾驶员状态的差异主要影响报警安全车距但对极限安全车距影响甚微.%To improve the accuracy and reasonableness of the safety distance model,the compositive weighting mechod is used to analyze the factors of influence of the driver states,vehicle conditions,natural environment and road conditions having influence on the safety distance model.Simulations and the real vehicle experiments are done to put forward the suitability of the vehicle safety distance for the different drivers,vehicle conditions,natural environment and road conditions.The natural environment and road and vehicle conditions all have influence on the warning safety distance and critical safety distance,while driver states have main inflence on the warning safety distance,but little inflence on the critical safety distance.
