The invention relates to the technical field of vehicle control, in particular to a course angular velocity deviation compensation method and system under lane centering control. The compensation method comprises the steps that the position of a vehicle in a lane where the vehicle is located is obtained; calculating an expected course angular velocity of the vehicle according to the lateral error, the cycle time and the current vehicle speed; the measured current course angular velocity is obtained, calibration compensation is carried out, and the actual course angular velocity is calculated; and calculating a course angular velocity error according to the expected course angular velocity and the actual course angular velocity, and regulating and controlling the driving direction of the vehicle according to the course angular velocity error. The compensation system comprises a lane centering control module and a sensing unit connected with the lane centering control module; the calculation module is connected with the sensing unit through a data transmission module; and the automatic driving module is connected with the calculation module. Objective data presentation is carried out according to the data collected by the sensing unit, the deviation of the course angular velocity of the vehicle is compensated, and the centering performance of the vehicle is improved.
