Claims19
A system for detecting an occupant left unattended in a vehicle, comprising:
- a first detection unit configured to detect whether a vehicle is stopped or parked;
- a carbon dioxide measurement unit configured to measure a carbon dioxide concentration within the vehicle and detect an increase/decrease pattern of the measured carbon dioxide concentration;
- a determination unit in communication with the first detection unit and the carbon dioxide measurement unit and configured, in response to detecting that the vehicle is stopped or parked, to:
- determine, based on the measured carbon dioxide concentration within the vehicle, whether or not an occupant is left unattended in the vehicle;
- classify, based on the detected increase/decrease pattern of the measured carbon dioxide concentration, the occupant left unattended in the vehicle.
