Title:
ELECTROMAGNETIC SUSPENSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3722127
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic suspension device for a vehicle capable of passively coping with an input not to be controlled while performing active control on the input to be controlled, facilitating the active control, and improving energy efficiency.
SOLUTION: The electromagnetic suspension device for the vehicle is provided with an electromagnetic actuator 4 interposed between an upper side of a spring and a lower side of the spring in parallel with a spring element 7 and driven by an electric motor 8, and a motor controller 17 calculating a displacement input to the electromagnetic actuator 4 and controlling the electric motor 8 to have optimum damping force in accordance with the displacement input. An electric damping element (an electric resistor 20 or an electric resonant circuit 21) passively generating the damping force with the generative braking of the electric motor 8 with respect to the displacement input from the lower side of the spring is connected to a control circuit of the electric motor 8 in parallel.
