The invention discloses an automatic driving transverse control method and device, relates to the technical field of automatic driving, and mainly aims to improve the transverse control precision of a vehicle in an automatic driving mode and ensure the driving safety in the automatic driving mode. According to the main technical scheme, the method comprises the steps that the operation condition of a vehicle in an automatic driving mode is determined; deviation compensation is conducted on the yaw velocity or the steering wheel rotation angle of the vehicle under the different operation working conditions based on first specified period circulation, so that the compensated yaw velocity or the compensated steering wheel rotation angle corresponding to each first specified period is obtained; storing the compensated yaw velocity or the compensated steering wheel rotation angle corresponding to each first specified period into a specified directory; and on the basis of a second specified period, the compensated yaw velocity or the compensated steering wheel rotation angle corresponding to the last first specified period in the specified directory is cyclically utilized to execute transverse control over the vehicle.
