Abstract
A vehicle integrated control method includes 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.
Claims20
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.
