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.

Claims

1. A method for processing messages sent from different individual software applications in a same mobile vehicle, comprising:

receiving messages at the different individual software applications from at least one of an application generated message, a user generated message and a sensor generated message in the mobile vehicle and generating an outgoing message from the received messages in the mobile vehicle;

associating individual communication managers with individual software applications in the mobile vehicle, wherein the communication manager is configured to;

independently attach a message label to individual messages wherein the message label includes at least a destination address;

immediately transmit the message by passing the message through the individual communication managers associated with different individual software applications to a priority manager located in the network configured to;

receive all of the outgoing messages;

compare the priority value for all of the outgoing messages received with the priority values for other outgoing messages;

rank the outgoing message with respect to the other outgoing messages;

reassign new priority values to messages that relate to at least one of vehicle collision threat condition, critical crash situation, or crash indication message;

send the message with the new priority value to its destination address according to the message label;

receive the outgoing message at the destination address as an incoming message;

process the incoming message in the different real-time mobile vehicle applications in the mobile vehicle according to the message labels.

2. A method according to claim 1 wherein the communication manager receives a first message, then receives a second message, compares the two messages, ranks the two messages, reassigns new priority values to a second message such that the second message now has a higher priority value than the first message received, wherein the reassigned second message preempts action on the first message received.

3. A method according to claim 1 wherein the communication managers include logging managers individually associated with individual software applications, the logging managers each independently attaching logging labels to individual messages generated by the associated individual software applications.

4. A method according to claim 3 wherein the logging managers independently log individual messages according to the logging labels attached to the individual messages.

5. A method according to claim 1 wherein the communication manager includes security managers individually associated with individual software applications, the security managers each independently attaching security labels to individual messages generated by the associated individual software applications.

6. A method according to claim 1 wherein the priority manager assigns different priority values to individual sensor data messages received from a sensor application according to a degree of possible vehicle collision associated with the individual sensor data messages.

7. A method according to claim 6 wherein messages indicating a vehicle collision threat condition are assigned a high priority value by the priority manager in the vehicle that causes other communication managers in the vehicle to process vehicle collision threat condition messages before other mobile vehicle messages.

8. A method according to claim 1 including receiving the messages from different processors in the mobile vehicle over different communication links.

9. A method according to claim 1 wherein the different communication links include a wireless communication link and a serial communication link.

10. A method according to claim 1 including:

receiving image sensor data from an image processor;

processing the sensor data in one of the applications when a security label is identified in the sensor data;

logging the image sensor data when a logging label is identified in the image sensor data; and

prioritizing the processing of the image sensor data by one of the applications according to a priority label in the image sensor data.

11. A method according to claim 10 including:

sending a brake message to a brake control processor when an object in the image data is identified as being within a predetermined range of the mobile vehicle;

attaching a logging label to the brake command; and

assigning a high priority value to a priority label in the brake command.

12. A method according to claim 10 including sending an annunciation message to speakers in the mobile vehicle when an object in the image data is identified as being within a predetermined range of the mobile vehicle.
