The invention discloses a vehicle deviation detection method and device and a medium, and is suitable for the technical field of intelligent automobiles. When it is detected that the current vehicle is in the straight driving state, a steering wheel angle parameter output by the current vehicle under the transverse control function and a self-learning strategy is obtained, and the self-learning strategy is correspondingly obtained according to the relation between the current driving parameter of the current vehicle and the last self-learning angle value; determining a direction offset angle of the current vehicle according to the steering wheel angle parameter; and determining the corresponding deviation degree according to the direction deviation angle and the deviation angle threshold value. According to the method, in the straight driving state of the vehicle, the transverse control function and the self-learning strategy of an auxiliary system ADAS of the vehicle are combined, it is ensured that a reasonable direction offset angle is obtained, the vehicle offset degree is distinguished according to the direction offset angle, the detection method is made to accurately, efficiently and objectively evaluate the deviation degree of the vehicle, the offset detection accuracy is improved, and the detection efficiency is improved. And the safety risk caused by vehicle deviation is effectively avoided.

    本发明公开了一种车辆跑偏的检测方法、装置及介质,适用于智能汽车技术领域。在检测到当前车辆处于直线行驶状态下,获取当前车辆在横向控制功能以及自学习策略下输出的方向盘转角参数,其中,自学习策略由当前车辆的当前行驶参数与上一次自学习角度值的关系对应得到;根据方向盘转角参数确定当前车辆的方向偏置角度;根据方向偏置角度与偏置角度阈值确定对应的跑偏程度。该方法在车辆直线行驶状态下,结合车辆的辅助系统ADAS系统的横向控制功能以及自学习策略,确保得到合理的方向偏置角度,根据方向偏置角度区分车辆偏置程度,使得检测方法精准高效,客观评价车辆的跑偏程度,提高偏置检测的准确性,有效避免车辆跑偏带来的安全风险。
