Secure log capture

A log collecting system for a vehicle, comprising:

• a first controller;
• a second controller;
• and
• a third controller,
• wherein the first controller is programmed to:
• responsive to detecting a failure, generate a failure event based on an analytics library,
• identify the second controller and the third controller as related to the failure event,
• identify logs of the first controller, the second controller and the third controller as related to the failure event,
• collect logs of the first controller, and
• transmit a failure message including a request for the logs of the second controller and logs of the third controller to the second controller,
• the second controller is programmed to:
• responsive to receiving the failure message from the first controller, collect logs of the second controller as requested, and send the request for logs of the third controller to the third controller,
• send a request for security token to a server, and
• responsive to receiving the security token from the server, upload the logs of the second controller as collected using the security token to the server, and send the security token to the first controller and the third controller,
• the third controller is programmed to:
• responsive to receiving the request for logs, collect the logs as requested, and
• upload the logs of the third controller as collected using the security token to the server, and
• the first controller is further programmed to:
• responsive to receiving the security token from the second controller, upload the logs of the first controller as collected using the security token to the server.

A vehicle system for collecting diagnostics data, comprising:

• an infotainment controller;
• a gateway controller;
• and
• a telematics control unit (TCU),
• wherein the infotainment controller is programmed to:
• responsive to detecting a failure, generate a failure event based on an analytics library and assign a global event identification (GEID) to the failure event,
• identify the gateway controller and the TCU as related to the failure event,
• identify logs of the infotainment controller, the gateway controller and the TCU as related to the failure event,
• collect logs of the infotainment controller and associate the logs with the GEID, and
• transmit a failure message including the GEID, a request for the logs of the gateway controller and logs of the TCU to the gateway controller,
• the gateway controller is programmed to:
• responsive to receiving the failure message from the infotainment controller, collect logs of the gateway controller as requested and associate the logs with the GEID,
• send the GEID and the request for logs of the TCU to the TCU,
• send a request for security token to a server, and
• responsive to receiving the security token from the server, upload the logs of the gateway controller as associated with the GEID to the server using the security token, and send the security token to the infotainment controller and the TCU,
• the TCU is programmed to:
• responsive to receiving the request for logs, collect the logs as requested and associate the logs with the GEID, and
• upload the logs of the TCU as associated with the GEID to the server using the security token, and
• the infotainment controller is further programmed to:
• responsive to receiving the security token from the gateway controller, upload the logs of the infotainment controller as associated with the GEID to the server using the security token.
