Abstract
A vehicle can include: an engine; an engine-off timer configured to detect an engine-off time for which the engine is turned off; an air temperature sensor configured to detect a temperature of air sucked into the engine; a water temperature sensor configured to detect a temperature of water in the engine; and a controller configured to determine whether the engine-off timer is operating normally based on the engine-off time detected by the engine-off timer, the temperature of air sucked into the engine detected by the air temperature sensor, and the temperature of water in the engine detected by the water temperature sensor.
Claims20
A vehicle comprising:
- an engine;
- an engine-off timer configured to detect an engine-off time for which the engine is turned off;
- an air temperature sensor configured to detect a temperature of air sucked into the engine;
- a water temperature sensor configured to detect a temperature of water in the engine;
- and
- a controller configured to determine whether the engine-off timer is operating normally based on the engine-off time detected by the engine-off timer, the temperature of air sucked into the engine detected by the air temperature sensor, and the temperature of water in the engine detected by the water temperature sensor.
An engine-off timer diagnosis method of a vehicle, the method comprising:
- detecting an engine-off time for which an engine of the vehicle is turned off using an engine-off timer;
- determining a temperature of air sucked into the engine which is detected using an air temperature sensor;
- determining a temperature of water of the engine which is detected using a water temperature sensor;
- and
- determining whether the engine-off timer is operating normally based on the engine-off time detected by the engine-off timer, the temperature of air sucked into the engine detected by the air temperature sensor, and the temperature of water in the engine detected by the water temperature sensor.
