A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.

A motor vehicle has a metal frame, active suspensions for supporting respective wheels, and a heat exchange system for managing heat of at least one component of the active suspensions; the heat exchange system is provided with a heat exchange circuit, which has a pump for supplying a heat exchange liquid, a heat exchanger, at least one heat exchange segment in the active suspensions, a return branch from the active suspensions towards the pump, and a delivery branch from the pump towards the active suspensions; at least one of the return and delivery branches comprises a metal pipe, which is free of thermal insulators and is arranged along the metal frame to transfer heat to the latter; in particular, the heat exchange is adjusted by varying the speed of the pump.

Provided herein is an apparatus and system including a fluid control system for suspension control that is also employed to circulate lubricating oil for an internal combustion engine. A vehicle may include a fluid pump that includes at least two distinct pump circuits, namely, a first distinct pump circuit and a second distinct pump circuit; a valve control block; and at least one fluid damped suspension damper. The first distinct pump circuit of the fluid pump is in fluid communication with at least one fluid damped suspension damper. The second distinct pump circuit of the fluid pump is in fluid communication via the valve control block with an oil circulation system of an internal combustion engine.

The present disclosure includes a jounce bumper with a main body and an insert. The main body includes a first polymeric material. The insert is integral with the main body and includes a second polymeric material that is different from the first polymeric material. The insert further includes a first plate, a second plate, and a connecting lattice that connects the first plate and the second plate together. The first polymeric material of the main body is between the first plate and the second plate, and is within the connecting lattice.

In one embodiment, one or more suspension systems of a vehicle may be used to mitigate motion sickness by limiting motion in one or more frequency ranges. In another embodiment, an active suspension may be integrated with an autonomous vehicle architecture. In yet another embodiment, the active suspension system of a vehicle may be used to induce motion in a vehicle. The vehicle may be used as a testbed for technical investigations and/or as a platform to enhance the enjoyment of video and/or audio by vehicle occupants. In some embodiments, the active suspensions system may be used to perform gestures as a means of communication with persons inside or outside the vehicle. In some embodiments, the active suspensions system may be used to generate haptic warnings to a vehicle operator or other persons in response to certain road situations.

A vehicle lift spacer apparatus for a vehicle shock is disclosed and configured for increasing a height of a vehicle without potentially over-extending or damaging the vehicle's suspension. In at least one embodiment, a spacer body provides a lift portion having a lift height and a preload portion positioned below the lift portion and having a preload height. During use, with a bottom surface of the preload portion positioned in substantially abutting contact with an upper surface of a coil spring of the vehicle shock, the coil spring is preloaded relative to a shaft of a strut of the vehicle shock and compressed by a distance equal to the preload height of the preload portion, while an overall height of the vehicle shock is increased by an amount equal to the lift height of the lift portion and the preload height of the preload portion.
