利用几何知识,考虑车辆轮胎侧偏性,得出主线为直行、平曲线左转和右转情况下紧急避险车道驶入角计算方法;通过ADAMS/Car行车动力分析软件,模拟不同主线下车辆以120km/h的速度和保证横向稳定性的最小转弯半径驶入避险车道的情况,运用软件后处理程序,输出横向加速度和轮胎侧偏角变化图,分析车辆在避险车道入口位置的横向稳定性,验证驶入角的计算方法的合理性,并对不同主线避险车道入口位置进行危险等级划分。 Using geometric knowledge, considering the vehicle tire side-offset, the method of calculation of the approach angle of the emergency avoidance lane with the main line straight, flat curve turning left and right is obtained. By ADAMS / Car driving dynamics analysis software, With the speed of 120km / h and the minimum turning radius to ensure lateral stability into the safe haven, using the software post-processing program, the output lateral acceleration and tire slip angle changes, the analysis of the vehicle in the safe haven entrance horizontal position Stability, verify the reasonableness of the calculation method of entry angle, and classify the danger level of the entrance of safe haven lane on different main lines.
