    • A vehicle suspension system including: (a) a suspension spring interconnecting a vehicle body and a wheel; (b) an actuator having an electric motor, such that the actuator is capable of generating, based on a force of the electric motor, an actuator force forcing the body and the wheel toward and away from each other, and causing the generated actuator force to act as a damping force against displacement of the body and the wheel; and (c) a control device for controlling the actuator force generated by the actuator, by controlling operation of the electric motor. The control device is capable of establishing a constant-force generating state in which the actuator force is constantly generated as a constant actuator force by the actuator with supply of an electric power thereto from a battery as an electric power source of the electric motor such that the generated constant actuator force acts in a rebound direction or a bound direction. The control device controls the constant-force generating state, based on a charge state of the battery.
    • 一种车辆悬架系统,包括:(a)将车体和车轮相互连接的悬架弹簧; (b)具有电动机的致动器,使得所述致动器能够基于所述电动机的力产生致使所述主体和所述车轮朝向和远离彼此的致动器力,并且使所产生的致动器力 作为抵抗身体和车轮位移的阻尼力; 和(c)通过控制电动机的动作来控制由致动器产生的致动器力的控制装置。 控制装置能够建立恒力产生状态,其中致动器力通过致动器作为恒定的致动器力而始终产生,该致动器从作为电动机的电源的电池向其提供电力,使得 所产生的恒定致动器力作用在回弹方向或束缚方向上。 控制装置基于电池的充电状态来控制恒定力产生状态。
