摘　　要：车身电子稳定系统是汽车重要的电子系统之一,它能够明显提高车辆高速避障能力,行业内主要采用正弦停滞试验测试车身电子稳定系统性能。文章借助机器人开展了正弦停滞试验,首先对试验结果是否满足国家标准进行了分析,然后对横摆角速度、质心侧偏角进行进一步分析,结果表明横摆角速度与质心侧偏角能够有效表征试验过程中车辆状态,为车辆车身稳定系统性能评价提供参考。As one of the important part of automobile,electronic stability control system can improve the ability of obstacle avoidance effectively and the sine with dwell test is used to verify the performance of electronic stability control.The sine with dwell test was carried out under the robot.Firstly,The test results are verified to meet the national standard,and then the yaw rate and the mass center side slip angle are further analyzed.The results show that the yaw rate and mass center side slip angle can effectively characterize the state of the vehicle during the test and provide reference for vehicle electronic stability control performance evaluation.
