摘　　要：对车辆直道行驶时障碍物突现和弯道路面状况紧急变化时的车辆操作特性进行了研究。采用一种新型的交通环境驾驶模拟装置,研究紧急避障时的操作方式和反应时间及弯道行驶时的转向回避模式。结果表明,在直道行驶紧急避障操作时,年轻被试者比年长被试者的制动反应时间少约0.25 s,且制动操作比转向操作要早,车辆转向共振频率对紧急避障操作有一定的影响。An experimental study was conducted on drivers＇ driving characteristics under emergency conditions. The collision avoidance maneuvers were examined by using a driving simulator to study the reaction time and modes of operation on straight and curvy roads. The results show that most drivers avoided the suddenly emerging obstacle first by a braking action followed by a steering action. The reaction time of older drivers is increased by 0.25 second for the breaking action. The resonant frequency of the steering system has an effect on avoid maneuver under emergency conditions.
