Abstract: It is an object of the invention to provide a suspension system configured to execute a control for avoiding a state in which an operation of an electric motor which is a power source of an electromagnetic actuator is kept halted at a certain operational position while the motor is generating a motor force. Where a target rotational position of the motor becomes equal to a specific operational position (e.g., a rotational position at which an electrifying current amount of one phase reaches a peak value), a control for shifting the target rotational position by δθ is executed. Where the rotational position of the motor is kept located at the certain position for a time period longer than a prescribed time, a control for changing the rotational position of the motor is executed. According to the present suspension system, it is possible to suppress imbalance in heat generation in the motor and to thereby reduce a load to be applied to the motor. Accordingly, a suspension system with high utility is realized.

Abstract: An air suspension system is configured to adjust and maintain a desired vehicle ride height and spring rate. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A controller receives ride height input data and adjusts pressures within the primary and piston airbags until the desired ride height and spring rate is achieved. The controller accommodates for system hardware differences by varying flow rates into and out of the primary and piston airbags relative to each other.
