The control device determines, based on the vehicle information, whether the driver has driving preference of emphasizing the steering stability performance of the vehicle or driving preference of emphasizing the ride comfort performance of the vehicle, and, according to the determined driving preference, changes an acceleration of the seat by controlling the seat suspension.

An axle load monitoring system for a load-transporting motor vehicle having one or more auxiliary axles wherein the monitoring system detects a noncompliant carrying-weight condition when the current gross vehicle weight is more than a prescribed maximum allowable gross vehicle weight assigned thereto and/or the current carrying weight of any primary axle and any designated axle group is more than a prescribed maximum allowable carrying weight assigned thereto. And if the current gross vehicle weight is equal to or less than the prescribed maximum allowable gross vehicle weight and the current center of gravity of the vehicle is in a compliance-manageable range which is established by the monitoring system and specific to the vehicle, the monitoring system recommends auxiliary axle usage that would result in compliance with the prescribed maximum and minimum allowable carrying weight assigned to each of the primary axles, any designated axle group and any utilized auxiliary axle.

An object of the present invention is to obtain an electromagnetic suspension apparatus capable of meeting a request to improve ride comfort irrespective of a magnitude of a spring constant preset in a spring member.
