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.
