Abstract:
Provided is an apparatus for sensing a remaining passenger in a vehicle and generating an alarm. The apparatus includes a first sensor unit provided on the ceiling of the inside of the vehicle and configured to sense presence or absence of a remaining passenger per seat when a door of a driver's seat is open in an engine off or on state, and a controller configured to generate an alarm when there is a remaining passenger in a seat other than the driver's seat when the engine is turned off and to determine whether the door of the driver's seat is closed and generate an alarm when the first sensor unit senses exit of a driver and presence of a remaining passenger.

Claim (Index 1):
An apparatus for sensing a remaining passenger in a vehicle and generating an alarm, comprising:\n a first sensor unit provided on the ceiling of the inside of the vehicle and configured to sense presence or absence of the remaining passenger per seat when a door of a driver's seat is open in an engine off or on state; a second sensor unit provided at an external doorknob of the vehicle; and a controller, wherein the controller generates the alarm when there is the remaining passenger in a seat other than the driver's seat in a state that the engine is turned off, wherein each of the first sensor unit and the second sensor unit is composed of at least one radar sensor, and the controller determines whether an object is present using transmission and reception time for which a signal transmitted by the first sensor unit or the second sensor unit to a predetermined area is reflected and received and determines whether the object is a person by comparing the signal with predetermined heartbeat patterns through waveform analysis, wherein the second sensor unit is configured to sense the object within a predetermined range, wherein the controller operates the second sensor unit when the door of the driver's seat switches to a closed state after the first sensor unit, which has operated according to opening of the door of the driver's seat in an engine on state, senses exist of the driver and presence of the remaining passenger and generates the alarm when the object sensed by the second sensor unit is out of the predetermined range, and wherein the controller periodically extracts waveforms of reflected signals received by the first sensor unit and generates the alarm when an abnormal pattern according to abrupt change is sensed.
