Abstract
An apparatus for warning reduction in fuel efficiency of a vehicle includes a driving sensor configured to sense driving of the vehicle. A window position sensor is configured to sense an opened degree of each window in the vehicle. A controller is configured to enable a fuel efficiency reduction predictor when the window position sensor senses that a window of the vehicle is opened, in the state in which the driving sensor senses the driving of the vehicle, the fuel efficiency reduction predictor predicting reduction in fuel efficiency depending on the opened degree of each window sensed by the window position sensor.
Claims9
An apparatus for warning reduction in fuel efficiency of a vehicle, the apparatus comprising:
- a driving sensor configured to sense driving of the vehicle;
- a window position sensor configured to sense an opened degree among a plurality of detectable opened degree ranges of each window in the vehicle;
- a controller configured to enable a fuel efficiency reduction predictor to start predicting, in real time, reduction in fuel efficiency depending on the opened degree of each window sensed by the window position sensor only when the window position sensor senses that a window of the vehicle is opened, upon sensing the driving of the vehicle by the driving sensor;
- a warning determiner configured to generate a warning signal depending on a sum of reduction in fuel efficiency for the windows, which is predicted by the fuel efficiency reduction predictor, exceeding a threshold value;
- and
- a warner configured to issue a warning to a driver depending on a warning signal from the warning determiner.
A method for warning reduction in fuel efficiency of a vehicle, the method comprising steps of:
- sensing, by a driving sensor, driving of the vehicle;
- sensing, by a window position sensor, an opened degree among a plurality of detectable opened degree ranges of each window in the vehicle;
- predicting, by a fuel efficiency reduction predictor, reduction in fuel efficiency depending on the opened degree of each window;
- generating, by a warning determiner, a warning signal depending on a sum of reduction in fuel efficiency for the windows, which is predicted by the fuel efficiency reduction predictor, exceeding a threshold value;
- and
- issuing, by a warner receiving the warning signal, a warning to a driver,
- wherein a controller enables the fuel efficiency reduction predictor to start predicting, in real time, the reduction in fuel efficiency only when the window position senses that a window of the vehicle is opened upon sensing the driving of the vehicle.
