The invention provides a real-time acquisition and measurement apparatus of vehicle attitude, a vehicle intelligent control system and a vehicle, in order to realize real-time level and inclination double-angle measurement; according to a self-preset program, a tension sensor of high sensitivity and an integratedly configured one-chip microcomputer are used, in order to accomplish real-time measurement of vehicle attitude. When attitude of a sealed container changes, liquid which is not fully filled in the container, such as mercury, flows accordingly; the upper surface of the liquid keeps level, the lower surface shows the same inclination angle along with the attitude change of the container, so that liquid level difference of the liquid appears at the direction of height, and center of gravity position of the integration of the liquid and the sealed container changes accordingly; by means of gravity of four tension sensor real-time determination points which are arranged in the four corners of the sealed container, change status of the center of gravity position of the integration is obtained; by means of the self-preset program of the one-chip microcomputer, the attitude change of the installing surface of the real-time acquisition and measurement apparatus of vehicle attitude relative to the horizontal plane is output.
