PROBLEM TO BE SOLVED: To provide an electromagnetic suspension control device having a simple configuration which can improve gas mileage. SOLUTION: The coil 15 of the electromagnetic damper 3a on the left side is connected to the coil 15 of the electromagnetic damper 3b on the right side through the medium of first and second switches 25a, 25b on the left side, a switch 21 on the right side, and a variable resistor 2. By adjusting the switching between the ON positions and the OFF positions of the first and second switches 25a, 25b on the left side and the switch 21 on the right side, and by adjusting the magnitude of the resistance value of the variable resistor 22 in accordance with a road surface condition, the oscillation control mode can be changed. Because of this, a favorable ride can be secured in accordance with a road surface condition. For example, the oscillation control mode can be continuously changed by continuously changing the resistance value of the variable resistor 22, and the generation of an impact associated with the switching of the oscillation mode can be prevented. The power which is generated by the electromagnetic damper can be used for a power source of another electromagnetic damper at the time of control of oscillation, and the constitution can be made simple as compared with the case where another battery or another supply source of external energy is provided.
