Abstract: In one aspect of the present disclosure, a combined suspension and steering module is disclosed that is positionable between an in-hub motor and a body of a vehicle. The module includes a housing, an actuator connected to the housing and including first and second components, and a steering system that is in mechanical cooperation with the actuator to rotate at least one of the first and second components in relation to the housing. The second component is axially movable in relation to the first component and is configured for connection to the in-hub motor to transmit rotational force from the actuator to the in-hub motor to cause angular displacement of the in-hub motor to thereby steer the vehicle.

Abstract: 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.

Abstract: A suspension component includes a suspension spring, a screw actuator that is operable to compress and decompress the suspension spring upon supply of electrical power to the screw actuator, and locking structure that engages a portion of the screw actuator to restrain motion of the screw actuator to maintain a current degree of compression of the suspension spring.

Abstract: 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.

Abstract: 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.

Abstract: A switching array as described for connecting ones of a plurality of data sources to ones of a plurality of data sinks. The array includes source data busses which transmit from a connected source, data words, a connection mask and a connection designator. The connection mask has bit positions that map to individual data sinks. A multiplexer/control circuit module is associated with each individual data sink for controlling the interconnection of the data sink to a source data bus. Each multiplexer/control circuit module is connected to each source data bus and is responsive to an active state connection mask bit and a connection designator on a first source data bus, to establish a connection between an associated sink and the first source data bus. This configuration enables the multiplexer/control circuit module to establish a connection without reference to any other multiplexer/control circuit.

Abstract: A multiple node network is described wherein messages are transmitted between source and intermediate nodes to a destination node, the network including a message progress reporting system which employs a status word that enables the source node to determine a message's progress. Each parent node comprises a status word register for reporting a status word that indicates the progress of the message. The parent node further includes a routing mechanism for receiving a status word from a child node that indicates the message's progress in the child node and at succeeding nodes thereafter. The routing mechanism updates the status word in the status word register in accordance with the received status word.
