Abstract
The present invention provides an occupant classification apparatus for a vehicle. The occupant classification apparatus for a vehicle includes a sensor mat that is mounted on each seat in the vehicle to sense objects disposed on the seats. An impedance measurer is configured to measure a current based on impedance of the object using the sensor mat A controller is configured to analyze the current measured by the impedance measurer and estimate the object that corresponds to the analyzed result.
Claims15
An occupant classification apparatus for a vehicle, comprising:
- a sensor mat mounted at each seat in the vehicle to sense objects disposed on the seats;
- an impedance measurer configured to measure a current based on impedance of the object using the sensor mat, and to extract a first component and a second component from the measured current by converting the measured current into a frequency domain by Fourier transform;
- and
- a controller configured to analyze the first component and the second component output by the impedance measurer and estimate the object that corresponds to the analyzed result.
