1. A vehicle integrated control method, the method comprising:
determining a road surface status;
determining a vehicle status;
determining an integrated control mode by determining a control status of an electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status; and
controlling the electronic control suspension and an in-wheel system by determining a control amount based on the determined integrated control mode,
wherein determining the integrated control mode comprises:
determining the integrated control mode as a first mode when both the sprung mass and the unsprung mass ascend based on ascending of a vehicle body and compression of a spring;
determining the integrated control mode as a second mode when the sprung mass ascends and the unsprung mass descends based on the ascending of the vehicle body and tension of the spring;
determining the integrated control mode as a third mode when both the sprung mass and the unsprung mass descend based on descending of the vehicle body and the tension of the spring; and
determining the integrated control mode as a fourth mode when the sprung mass descends and the unsprung mass ascends based on the descending of the vehicle body and the compression of the spring.
