OCCUPANT SAFETY SYSTEM WITH CO2 DETECTION

An occupant (20) safety system (10) for a vehicle (12) includes a carbon-dioxide (CO2) sensor and a controller (22). The CO2 sensor is configured to determine a CO2 concentration in a passenger cabin (18) of the vehicle (12) while the vehicle (12) is not operating, i.e. parked. The controller (22) i...

Zusammenfassung:	An occupant (20) safety system (10) for a vehicle (12) includes a carbon-dioxide (CO2) sensor and a controller (22). The CO2 sensor is configured to determine a CO2 concentration in a passenger cabin (18) of the vehicle (12) while the vehicle (12) is not operating, i.e. parked. The controller (22) is configured to determine that the passenger cabin (18) is occupied by an occupant (20) based on the CO2 concentration in a passenger cabin (18) while the vehicle (12) is not operating. If the CO2 concentration is a concern while the vehicle (12) is not operating, the system (10) may respond by activating a notification means such as a vehicle (12) horn or alarm, or by ventilating the passenger cabin (18) via opening the windows or operating a blower of a HVAC system (10) of the vehicle (12).
