Control to Improve Driving Stability of a Heavy Vehicle With Electromagnetic Suspensions (Second Report: Control to Give a Sense of Unity With a Car Body)
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
The authors propose to improve the driving stability with an electromagnetic active suspension system. To give a driver a sense of unity with a car body, the electromagnetic actuators control to compensate low rigidity of a heavy vehicle. The study carried out by the authors showed it was important to reduce time lag between the roll angle of the front part of the frame and its torsion angle with keeping moderate balance of the magnitudes of the two angles. Then the active controller to satisfy these demands is proposed. The results of numerical simulations by a commercially available multibody dynamics software, experiments using test cars, and sensual tests of the drivers and crews show the proposed active suspension improves the sense of unity.
