This paper presents road tests of electromagnetic damper for automobiles. The authors propose electromagnetic damper system for automobiles for improved ride comfort and compatibility between stability and isolation. The electromagnetic damper (EMD) uses DC motor as generator, so it can electronically control damping force. Former trial EMD had linear characteristics of damping force, but the authors developed power electronics circuit for EMD to have nonlinear damping force, and proved that the EMD system has suitable ability for automobile damper from experiments using new damper system. This time, we equipped electromagnetic dampers with an automobile, and did the road tests to make sure of its nonlinearization of damping force.
