摘　　要：采用基于场景的试验方法,针对ESC的过度转向和不足转向的干预能力,在冰雪道路上进行了ESC测试,分别设置了滑行避障试验、制动避障试验和稳态圆周试验。结果表明,与滑行避障试验相比,制动避障可更有效地测试车辆ESC系统的性能,同时更接近于实际交通驾驶场景;采用质心侧偏角和横摆角速度跟随误差能有效分析ESC的控制效果,可作为车辆ESC系统在低附路面上的性能评价指标。An ESC test is conducted on snow-icing roads by adopting scenario-based test method to validate the capabilities of oversteer and understeer intervention. The tests include coasting obstacle-avoidance test,braking obstacle-avoidance test and steady circular test. The results show that compared with coasting obstacle-avoidance test,the braking obstacle-avoidance test can better test the performance of vehicle ESC system and is closer to driving scenario in real traffic condition. Using the tracking error of mass center side slip angle and yaw rate can effectively analyze the control effects of ESC,suiting to be the performance evaluation indicator for vehicle ESC system on low-adhesion road.
