    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 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 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. The routing mechanism further transmits the updated status word from the parent node to a source node upon the parent node having received status words from all child nodes to which the parent node transmitted the message whereby each succeeding parent node does not transmit its status word until all succeeding nodes have accumulated their status words and reported upward in the tree.

    摘要翻译： 描述了一种多节点网络，其中消息在源节点和中间节点之间传送到目的地节点，该网络包括消息进度报告系统，该系统采用能使源节点确定消息进度的状态字。 每个父节点包括状态字寄存器，用于报告指示消息进度的状态字。 父节点还包括路由机制，用于从子节点接收指示消息在子节点中的进程的状态字，以及其后的后续节点。 路由机制根据接收的状态字更新状态字寄存器中的状态字。 当父节点已经从父节点发送消息的所有子节点接收到状态字时，路由机制进一步将更新的状态字从父节点发送到源节点，由此每个后续父节点不发送其状态字直到所有 后续节点已经积累了他们的状态字，并在树上向上报告。
