The invention relates to the technical field of vehicle testing, in particular to a vehicle running deviation automatic detection method and system and a storage medium. The method comprises the steps of collecting steering wheel angle data in real time and calculating a distance change value between a vehicle and a lane line in real time; loosening the steering wheel and driving for a first set distance; if the steering wheel turning angle is not larger than the set angle and the distance change value between the vehicle and the lane line is not smaller than a second set distance, judging that the vehicle runs off-tracking; if the steering wheel turning angle is not larger than the set angle and the distance change value between the vehicle and the lane line is larger than a second set distance, judging that the vehicle does not run off-tracking; and if the steering wheel angle is greater than the set angle and the distance change value between the vehicle and the lane line is greater than a second set distance, judging that the steering wheel of the vehicle is not centered. Judgment is carried out through combination of the distance variation between the vehicle and the lane line and the steering angle variation of the steering wheel, vehicle running deviation and non-centering of the steering wheel can be effectively distinguished, and misjudgment in vehicle running deviation detection is prevented.
本发明涉及车辆测试技术领域,具体涉及一种车辆行驶跑偏自动检测方法、系统及存储介质。包括实时采集方向盘转角数据,并实时计算车辆与车道线距离变化值;松开方向盘行驶第一设定距离;若方向盘转角不大于设定角度,且车辆与车道线距离变化值不小于第二设定距离,则判断车辆行驶跑偏;若方向盘转角不大于设定角度,且车辆与车道线距离变化值大于第二设定距离,则判断车辆未行驶跑偏;若方向盘转角大于设定角度,且车辆与车道线距离变化值大于第二设定距离,则判断车辆的方向盘装配不居中。通过车辆距离车道线距离变化量结合方向盘转角变化量进行判断,能将车辆行驶跑偏与方向盘不居中有效区分,防止在车辆行驶跑偏检测中的误判断。
