  • Patent number: 8762610
    Abstract: A method for processing messages sent from software applications in a vehicle: Messages are received from an application, a user, or a sensor. The method generates outgoing messages based on message type received, and associates software applications with communication managers configured to attach message labels to messages, with the message label having at least a destination address. The outgoing message is transmitted through communication managers associated with software applications, arriving at a priority manager within the network. The priority manager receives outgoing message and ranks the priority value for the messages, and reassigns new priority values to messages that relate to collision circumstances. The priority manager sends the message with the new priority value to its destination address based on the message label. The message is received as an incoming message to be processed in the real-time vehicle applications according to the message labels.

  • Patent number: 8751712
    Abstract: A method for processing messages sent between multiple software applications in a vehicle comprises generating an outgoing message based on a received message. The received message includes an application generated message, a user generated message, or a sensor generated message in the vehicle. The method associates communication managers with software applications in the vehicle, and the communication managers include priority managers that assign a high priority value to messages that relate to vehicle safety, crash mitigation, collision threat, collision avoidance, or crash indication. The priority managers compare priority values of the outgoing messages and rank the importance of the outgoing messages. The method uses the communication managers to attach a message label to high priority messages labeling them as “new”. The new messages are immediately transmitted before the lower priority messages through the communication managers.
