The invention provides a rear axle steering valve group, an axle steering centering hydraulic control system and a vehicle. The rear axle steering valve group comprises a hydraulic control proportional throttle valve, wherein the hydraulic control proportional throttle valve is arranged between an oil source and a first executing mechanism, the hydraulic control proportional throttle valve is provided with a throttle control port which is used for controlling the opening of the hydraulic control proportional throttle valve, the throttle control port is connected with the control oil source, the flow of the control oil source increases along with the increase of the wheel speed, and the opening of the hydraulic control proportional throttle valve is reduced along with the increase of the flow of the control oil source. By adopting the rear axle steering valve group, the running speed of the first executing mechanism can be controlled.
