Abstract
A vehicle monitoring device includes: a recurrence monitoring unit configured to, when an error that has occurred in an exhaust gas aftertreatment device is resolved, monitor recurrence of the error for a predetermined recurrence monitoring period; an output limiting unit configured to limit output of an internal combustion engine when the error recurs during the recurrence monitoring period; and a monitoring control unit configured to perform control to enable end of monitoring of the recurrence monitoring unit in a predetermined manufacturing process.
Claims5
A vehicle monitoring device comprising:
- a recurrence monitoring unit configured to, when an error that has occurred in an exhaust gas aftertreatment device is resolved, monitor recurrence of the error for a predetermined recurrence monitoring period;
- an output limiting unit configured to limit output of an internal combustion engine when the error recurs during the recurrence monitoring period;
- and
- a monitoring control unit configured to perform control to enable end of monitoring of the recurrence monitoring unit in a predetermined manufacturing process.
A vehicle monitoring method executed by a vehicle monitoring device, the method comprising:
- recurrence monitoring, when an error that has occurred in an exhaust gas aftertreatment device is resolved, monitoring recurrence of the error for a predetermined recurrence monitoring period;
- limiting output of an internal combustion engine when the error recurs during the recurrence monitoring period;
- and
- monitoring control by performing control to enable end of monitoring during recurrence monitoring in a predetermined manufacturing process.
