Abstract
A method for controlling a vehicle capable of detecting the presence of a passenger in the vehicle includes steps of: scanning an interior of the vehicle based on ultrasonic signals and constructing spatial data on the interior of the vehicle; and re-scanning the interior of the vehicle based on ultrasonic signals when preset conditions are satisfied and outputting a sensing result when a change of the ultrasonic signals, which is greater than a reference value, is detected in the previously constructed spatial data.
Claims11
A method of controlling a vehicle, the method comprising steps of:
- determining whether or not an opening event of a rear door of the vehicle is detected after the vehicle is switched on;
- scanning an interior of the vehicle based on ultrasonic signals, and constructing first spatial data on the interior of the vehicle when the opening event of the rear door is not detected after the vehicle is switched on and before the vehicle moves;
- storing the first spatial data;
- scanning the interior of the vehicle based on ultrasonic signals and constructing second spatial data on the interior of the vehicle when the opening event of the rear door is detected after the vehicle is switched on and before the vehicle moves;
- determining that a passenger is present in the rear seat of the vehicle according to a change between the first spatial data and the second spatial data;
- and
- outputting a determined result that the passenger is present in the rear seat when the change between the first special data and the second spatial data is greater than a reference value.
4 more elements
A vehicle comprising:
- an ultrasound sensor configured to output ultrasonic signals having various frequency bands;
- a sensor configured to detect an opening event of a rear door of the vehicle;
- a memory configured to store a spatial data;
- and
- a controller configured to:
- determine whether or not an opening event of a rear door of the vehicle is detected after the vehicle is switched on,
- construct first spatial data on an interior of the vehicle by scanning the interior of the vehicle based on the ultrasonic signals when the opening event of the rear door is not detected after the vehicle is switched on and before the vehicle moves,
- storing the first spatial data in the memory,
- construct second spatial data on the interior of the vehicle by scanning the interior of the vehicle based on the ultrasonic signals when the opening event of the rear door is detected after the vehicle is switched on and before the vehicle moves,
- determine that a passenger is present in the rear seat of the vehicle according to a change between the first spatial data and the second spatial data, and
- output a determined result that the passenger is present in the rear seat when the change between the first special data and the second spatial data is greater than a reference value.
