Abstract
An alarm apparatus including a door sensor detects entering and exiting of a person to/from a vehicle based on information acquired by the door sensor, determines whether a specific person is left behind inside the vehicle based on the detection result when a driver has left the vehicle, and outputs an alarm when the specific person is left behind inside the vehicle. The information acquired by the door sensor includes whether a location in which a door opening/closing operation has been performed corresponds to a location related to the specific person, or whether a time period when the door opening/closing operation has been performed corresponds to a time period when the specific person frequently enters and exits the vehicle.
Claims5
An alarm apparatus comprising:
- a door sensor configured to output sensor information indicating presence or absence of a door opening/closing operation of a vehicle, and whether a location in which the door opening/closing operation has been performed corresponds to a location related to a specific person or whether a time period when the door opening/closing operation has been performed corresponds to a time period when the specific person frequently enters and exits the vehicle;
- and
- a controller configured to acquire the sensor information from the door sensor, and generate alarm information upon determining, based on the sensor information, that a driver has exited the vehicle and the specific person is left behind inside the vehicle.
An alarm apparatus comprising a door sensor, the alarm apparatus configured to detect entering and exiting of a person to/from a vehicle based on information acquired by the door sensor, determine whether a specific person is left behind inside the vehicle based on a detection result when a driver has left the vehicle, and output an alarm when the specific person is left behind inside the vehicle,
- wherein the information acquired by the door sensor includes whether a location in which a door opening/closing operation has been performed corresponds to a location related to the specific person, or whether a time period when the door opening/closing operation has been performed corresponds to a time period when the specific person frequently enters and exits the vehicle.
An alarm method comprising:
- acquiring, by an alarm apparatus including a door sensor from the door sensor, sensor information indicating presence or absence of a door opening/closing operation of a vehicle, and whether a location in which the door opening/closing operation has been performed corresponds to a location related to a specific person or whether a time period when the door opening/closing operation has been performed corresponds to a time period when the specific person frequently enters and exits the vehicle;
- and
- generating alarm information upon determining, based on the sensor information, that a driver has exited the vehicle and the specific person is left behind inside the vehicle.
