车辆行驶跑偏试验方法研究与分析

车辆保持直线行驶的能力是汽车行驶稳定性的一个重要评价项目,为测量车辆行驶跑偏量,国家颁布了相应法规,规定了相应的试验方法。文章详细介绍了车辆行驶跑偏试验方法,针对标准要求搭建检测系统并进行相关试验。由于标准要求定位精度过高,因此提出了一种简化的试验设备测试方法,通过试验结果比较,发现简化方法精度满足厘米级检测要求,适用于汽车制造商进行车辆跑偏检测工作,降低测试成本。

Research and Analysis of Vehicle Running Deviation Test Method

The ability of a vehicle to maintain a straight line is an important evaluation item for vehicle driving stability.In order to measure the vehicle running deviation,the state promulgated the corresponding laws and regulations and stipulated the corresponding test methods.In this paper,the test method of vehicle running deviation is introduced in detail,the detection system is built according to the standard requirements and relevant tests are carried out.Because the positioning accuracy required by the standard is too high,a simplified test method of test equipment is proposed.Through the comparison of test results,it is found that the accuracy of the simplified method meets the centimeter level detection requirements,and it is suitable for automobile manufacturers to carry out vehicle deviation detection and reduce the test cost.
