  • Patent number: 7999408
    Abstract: A power, ground and communication architecture (100) utilizes hubs (105, 110, 115). Each hub (105, 110, 115) contains computing, communication and power management elements (135, 140). Hubs (105, 110, 115) may be connected to multiple other hubs (105, 110, 115) to distribute communication and power in a freeform web-type arrangement, specific tree, bus or star arrangements are not required. Standardized wiring harness segments (120) are used to join the hubs (105, 110, 115) and control elements. Each of the strands in the web may be an independent point-to-point bus and isolated power line.

  • Patent number: 7733841
    Abstract: A vehicle network and method for communicating information within a vehicle. The network includes a plurality of network elements joined by communication links. A data frame is provided for communicating information between a first device and a second device attached to the network. A network element in the network is capable of mapping a first resource on an incoming communication link of the network element to a second link resource of an outgoing communication link of the network element. The network element further has ports for receiving the data frame from the first link resource of the incoming communication link and for communicating the data frame to the second link resource of the outgoing communication link. The mapping may be done statically or dynamically such as based on information stored in the network element or based on information stored in the data frame.

  • Patent number: 7600114
    Abstract: A first vehicle obtains from a certification authority a certification that an authentic vehicle is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic vehicle, and may be implemented. The first vehicle utilizes the cryptographic key obtained from the certification authority in cryptographic communication with a second vehicle, and determines whether the second vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication. Upon determining the second vehicle is the authentic vehicle, the first vehicle may communicate further with the second vehicle.

  • Patent number: 7599377
    Abstract: A system and method for tunneling standard bus protocol messages through an automotive switch fabric network. When a bus protocol message arrives on a connecting node in the network, a bus driver in the node will capture the message and store it into a message buffer where the message can be further processed by a tunneling application. Each received bus protocol message will be broken, or combined, to suit the available packet size of the underlying transmit layer of the switch fabric network. Data portions such as message identification, sequence number, port number, bus data type, and data length are reserved in each data packet. If the message is being broken down, the sequence number is used to differentiate the broken segments of the bus protocol message. The bus data type is used to indicate the type of protocol data being transmitted over the switch fabric. The same tunneling application may be used to reassemble the bus protocol message at a receiving node.

  • Patent number: 7428449
    Abstract: System and method for determining a workload level for a driver of a vehicle. The system includes a transceiver, a positioning unit, and a controller. The transceiver is capable of receiving data from a remote location. The data includes a remote workload level and a remote geographic position associated with the remote workload level. The positioning unit is capable of determining a current position of the vehicle. The controller is configured to compare the current position of the vehicle with the remote geographic location. If the current position of the vehicle is within a predetermined range of the remote geographic position, then a workload level for the vehicle will include at least in part the remote workload level.

  • Patent number: 7325135
    Abstract: A vehicle accesses a configuration database to determine whether a reconfiguration function is authorized. The reconfiguration function may involve, for example, installing the component in the vehicle, removing the component from the vehicle, replacing the component with another component in the vehicle, replacing another component in the vehicle with the component, modifying the component, upgrading the component and rendering the component operable. Upon determining that the reconfiguration function is authorized, the vehicle allows the reconfiguration function to be performed. The reconfiguration function may be authorized based on a type of the vehicle, a type of the component or a combination of configuration elements in a current configuration of the vehicle.

  • Patent number: 7324892
    Abstract: A system and method for coordinating parameters in a switch fabric network (22) of a vehicle (20). The network (22) has a plurality of nodes (24) that are interconnected by communication links for the transmission of data packets there between. Events in the vehicle (20) may be handled in connection with a vehicle parameter. One example of a vehicle parameter that may be used in the vehicle is the rotation of a crank shaft in the vehicle. An application uses that information to make a determination whether change a setting of a device in the vehicle (20). If so, the application generates a command data packet and transmits the command data packet over the switch fabric network (22). The command data packet transmitted by the application includes the new setting for the device along with a value of the vehicle parameter when the new setting should occur in the device.

  • Publication number: 20070296559
    Abstract: A system and method for controlling a hand-held communication device in a vehicle is disclosed. In an embodiment of the invention, the hand-held communication device is controlled by a driver advocate or workload manager module. To control the cellular telephone, at least a transmitter is coupled to the diagnostic connector (e.g., an OBD-II connector) in the vehicle, which can be coupled directly to the connector via a dongle or can be coupled via a cable. The transmitter receives instructions from the workload manager module and transmits them to the cellular telephone, preferably via a short-range wireless protocol such as Bluetooth, although fully wired links can also be used as well. So that the cellular telephone can properly interpret and act on these commands, an application program (e.g., a Java applet) is preferably downloaded to the telephone through any suitable means.

  • Patent number: 7310327
    Abstract: An independent, broadcast medium (32) is used to communicate an time reference to each element: switch element (36), active element (14-20) or passive element, of an in-vehicle network (30). Each element (36) in the network accepts the time information, i.e., a time reference from the source. The time reference is then used by each element (36) to adjust an internal clock of the element. Commands may then be sent to the elements to occur at a particular time.
