摘　　要：为从车辆行驶安全的角度出发,揭示紧急避让情况下驾驶员心理负荷的变化,利用动态心电分析仪、Frecord数据采集系统和动态GPS,进行紧急避让情况下驾驶员生理反应的试验。基于多元线性回归统计方法,对试验数据进行拟合,建立了同一车道上汽车距前方障碍物距离、汽车行驶速度、紧急制动时最大制动踏板速度、为避障而突然转向时最大转向盘角速度和驾驶员心率变化量之间的多元线性回归模型,对诸参数之间的关系进行了分析。结果表明,车距障碍物距离对最大转向盘角速度和最大制动踏板速度的影响大于汽车行驶速度的影响,且随着行车速度的增加和车距障碍物距离的减小,驾驶员心理负荷增大。To reveal the change in driver＇s psychological burden under the condition of emergent obstacle avoidance, starting from the angle of vehicle operation safety, tests on driver＇s physiological responses under emergent obstacle avoidance are conducted by using Holter monitor, Frecord data collection system and dynamic GPS. Based on multivariate linear regression statistics, test data are fitted to get the multivariate linear regression models of driver＇s heart rate variation against the distance between vehicle and front obstacles in the same lane, vehicle speeds, the maximum braking pedal velocity and the maximum steering wheel angular velocity with the relationships between parameters analyzed. The results indicate that the distance between vehicle and obstacle has larger effects on the maximum steering wheel angular velocity and the maximum braking pedal velocity than vehicle speed has, and the driver＇s psychological burden increases with the rise in vehicle speed and the reduction in distance between vehicle and obstacle.
