摘要: A support system includes a primary actuator that transfers force between a sprung mass and an unsprung mass. A control system operates the primary actuator to provide additional control when a damper exceeds a capacity threshold. The control system changes the capacity threshold according to the environmental condition.

摘要: A vehicle includes a vehicle body, a wheel, a suspension system that supports the wheel relative to the vehicle body, a sensing system for determining an environmental condition ahead of the vehicle and a control system. The suspension system includes a primary actuator that transfers force between the wheel and the vehicle body, and a wheel hop damper that includes a moving mass and that transfers force between the wheel and the moving mass independent of the vehicle body to inhibit resonance of an unsprung mass formed by the wheel and a portion of the suspension system coupled thereto. The control system operates the primary actuator to provide additional secondary ride control when the wheel hop damper exceeds a capacity threshold. The control system changes the capacity threshold according to the environmental condition. The wheel hop damper may be a reaction mass actuator or a tuned mass damper.

摘要: A suspension actuator assembly includes a first actuator and a second actuator. The first actuator selectively applies a first force between an unsprung mass and a sprung mass of a vehicle to control movement therebetween. The second actuator selectively applies a second force between the unsprung mass and a reaction mass to damp movement of the unsprung mass. The second actuator is coupled to the first actuator to form the suspension actuator assembly as a singular unit.

摘要: A suspension system includes a primary actuator, an inertial actuator, and a controller. The primary actuator applies force between a sprung mass and an unsprung mass of a vehicle to control movement therebetween. The inertial actuator applies force between the unsprung mass and a reaction mass to damp movement of the unsprung mass. The inertial actuator has a threshold capacity. The controller controls the primary actuator and the inertial actuator. The controller determines a required damping of the movement of the unsprung mass, and apportions the required damping between the primary actuator and the inertial actuator.

摘要: A suspension actuator includes an upper mount, a lower mount, a first actuator mechanism, and a second actuator mechanism. The upper mount is connectable to a sprung mass of a vehicle. The lower mount is connectable to an unsprung mass of the vehicle. The first actuator mechanism forms a first load path between the upper mount and the lower mount. The first actuator mechanism is one of an electromagnetic linear actuator mechanism or a ball screw actuator mechanism. The second actuator mechanism forms a second load path in parallel with the first load path between the upper mount and the lower mount. The second actuator mechanism is one of a mechanical linear actuator mechanism, an air spring actuator mechanism, or a hydraulic actuator mechanism.

摘要: An active suspension system for a vehicle having a wheel that is subject to an external force includes an actuator having an output structure that is connected to the wheel, an energy storage device having a compressible chamber, a valve assembly that is operable to control flow of a working fluid between the actuator and the energy storage device, and a controller that determines whether to permit or resist motion of the output structure in response to the external force. The controller permits motion of the output structure by allowing fluid to flow from the actuator to the energy storage device using the valve assembly, thereby compressing the compressible chamber. The controller resists motion of the output structure by allowing fluid to flow from the energy storage device to the actuator using the valve assembly, thereby expanding the compressible chamber.
