Abstract
By a vehicle device for a vehicle, a server, or a communication management method, a log of an exchange is centrally managed, and a failure is detected in a communication establishment process, and a log estimated to be related to the failure is output when the monitoring unit has detected the failure.
Claims16
A vehicle device configured to be used for a vehicle, the device comprising:
- a monitoring unit configured to
- recognize a status of an exchange in a communication establishment process between an in-vehicle electronic control unit mounted on the vehicle and a connection destination on a network outside the vehicle,
- centrally manage a log of the exchange, and
- detect a failure in the communication establishment process;
- and
- a log output unit configured to output a log estimated to be related to the failure among the log centrally managed by the monitoring unit when the monitoring unit has detected the failure.
3 more elements
A server configured to be used on a network outside a vehicle, the server comprising:
- a log acquisition unit configured to acquire a log output from a vehicle device used for the vehicle, wherein the vehicle device is configured to centrally manage the log that is information of an exchange in a communication establishment process between an in-vehicle device mounted on the vehicle and a connection destination on the network outside the vehicle to output the log estimated to be related to a failure in the communication establishment process among the centrally managed log;
- a log storage configured to store the log acquired by the log acquisition unit from the vehicle device;
- a rule setting unit configured to set a detection rule for designating a cause identification log that is the log estimated to enable identification of a cause of the failure;
- and
- a setting transmission unit configured to transmit the detection rule set by the rule setting unit to the vehicle device for extracting, by the vehicle device, as the cause identification log, the log designated by the detection rule and output the log.
2 more elements
A communication management method executed by at least one processor, the method comprising:
- centrally managing a log that is information of the exchange in a communication establishment process between an in-vehicle electronic control unit mounted on a vehicle and a connection destination on a network outside the vehicle;
- detecting a failure in the communication establishment process;
- and
- outputting the log estimated to be related to the failure among the log managed by the monitoring process when having detected the failure.

A communication management method executed by at least one processor, the method comprising:
- acquiring a log output from a vehicle device used for the vehicle, wherein the vehicle device is configured to recognize and centrally manage the log that is a status of an exchange in a communication establishment process between an in-vehicle device mounted on the vehicle and a connection destination on the network outside the vehicle to output the log estimated to be related to a failure in the communication establishment process among the centrally managed log;
- storing the log acquired by the log acquisition process from the vehicle device;
- setting a detection rule for designating a cause identification log that is the log estimated to enable identification of a cause of the failure for each failure cause in the communication establishment process;
- and
- transmitting the set detection rule to the vehicle device for extracting, by the vehicle device, as the cause identification log, the log designated by the detection rule and outputting the log.
