Abstract
A system control method is provided for measuring a distance between a smart key and a vehicle. When the distance between the smart key and the vehicle is changed based on a predetermined distance whether a hydrogen leak occurs is detected by a hydrogen sensor detection controller. A driver is then informed of a hydrogen leak via a display on a cluster, a turn-on of an emergency light, and a warning sound of the vehicle. Alternatively, a starting-impossible state of the vehicle or shutting-down starting of the vehicle is maintained to ensure safety measures based on the concentration of the leaking hydrogen.
Claims9
A control method for a hydrogen leak determining system of a fuel cell vehicle which includes a plurality of hydrogen sensors disposed within the vehicle and configured to detect a hydrogen leak, the control method comprising:
- receiving a hydrogen concentration measured by the hydrogen sensors, by a controller, and measuring a distance between the vehicle and a smart key,
- determining, by the controller, whether the distance between the smart key and the vehicle is greater than or approaches a first set value;
- executing, by the controller, detection of the hydrogen sensors when the distance between the smart key and the vehicle exceeds or approaches the first set value;
- and
- determining, by the controller, whether a hydrogen leak occurs in the vehicle, using the hydrogen sensors,
- wherein the controller is further configured to:
- ventilate leaking hydrogen through a ventilator in response to determining that the hydrogen leak occurs.
