PROBLEM TO BE SOLVED: To improve the practicality of a vehicular suspension system provided with a plurality of electromagnetic shock absorbers for a plurality of wheels. SOLUTION: A plurality of contact relays 200 provided correspondingly to a plurality of the shock absorbers 30 are structured to usually produce a connection state in which motors 44 having a plurality of the shock absorbers 30 are connected to a power source 152 for all of the shock absorbers and to produce an interruption state in which the connection between the motors 44 and the power source 152 is interrupted for the shock absorbers 30 under the condition that a generated current of the motor 44 having one of a plurality of the shock absorbers 30 is predicted to exceed a set current, which is set up in consideration of an occurrence of a welding phenomenon of the relays 200. By producing the interruption state at an early stage to some extent in the process in which the generated current becomes larger, application of a large load to the power source 152 can be prevented while inhibiting the welding of a contact of the relays 200.
