Eco-run system, control program, and eco-run status notification device

摘要

The present invention is an eco-run system having an eco-run function that stops and restarts an internal combustion engine depending on a state of a vehicle. The eco-run system includes: table information that prescribes a relationship between a plurality of eco-run prohibition reasons and priorities in which a user is informed of the eco-run prohibition reasons; an eco-run ECU 10 that judges whether an eco-run prohibition reason occurs to the vehicle; and an eco-lamp 41 or a navigation apparatus that, when it is judged by the eco-run ECU 10 that the eco-run prohibition reason occurs to the vehicle, informs the user of the eco-run prohibition reason depending on the priorities prescribed by the table information.
