Abstract:
A method and system for positioning a vehicle chassis (304) in approximate alignment with a predetermined datum are provided. The vehicle (502) includes a first longitudinal end adapted to be pivotally connected to a substantially fixed point (506) and a second longitudinal end including at least one axle (312) and an operatively associated two-corner fluid suspension system (307, 309). According to the method, the fluid suspension system (307, 309) controls the alignment of the vehicle chassis (304) to be aligned with an artificial horizon represented as the predetermined datum.

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 is provided to control a spring constant in a real time by varying the shape of a piston that varies an effective hydraulic area of a diaphragm. An air suspension comprises an upper joint connected to a chassis frame, a piston(64) connected to an axle of a vehicle to deliver vibration from the ground, a diaphragm(60) making contact an outer surface of the piston according to the up/down movement of the piston, a partition wall(66) formed around the piston such that the partition wall makes contact with the diaphragm, and an actuator(70) installed in the piston to vary the outer diameter of the partition wall. The diaphragm is installed between the upper joint and the piston to store pressurized air therein.
