摘要
在交通部试验场利用动态心电分析仪、Frecord数据采集系统及动态GPS,研究驾驶员特征对紧急状况主观评价和车辆行驶控制的影响。研究表明,具有不同驾驶经验、个性、年龄特征的驾驶员对同一紧急状况做出的紧急度主观评价和制动操纵存在差异,其中驾驶经验的影响最明显。经验丰富的驾驶员采用减速度相对较小,变化相对平缓;相对于谨慎型驾驶员而言、鲁莽型驾驶员制动减速度变化剧烈;年龄对驾驶员操纵也有一定影响,通常年轻驾驶员会进行快速制动,这与驾驶员的生理状况有很大关系。研究结果可为驾驶员安全管理提供理论依据。
Electrocardiograph, Frecord data collecting system and dynamics GPS are utilized to study the effect of drivers＇ characteristics on the subjective judgment about the emergency degree and control of the vehicle motion. The data are analyzed and the results are obtained.It shows that the subjective judgment about the emergency degree is different according to the drivers＇ characteristics for the same situation. Compared with personality and age, driving experience effect is most obvious. The decelerating operation is different according to different emergency degree judged. This research can help us to understand driver behavior under emergency and also offer theory for driver management.
