20220185231
The present disclosure generally relates to temperature alert and mitigation systems, and more particularly to temperature alert and mitigation systems for passenger vehicles.
Passenger vehicles frequently carry vulnerable occupants such as infants or pets that are unable to exit the vehicle on their own. On certain occasions, a driver of the passenger vehicle inadvertently leaves the vulnerable occupant in the vehicle for a period of time in which a passenger compartment of the vehicle can be dangerously hot or dangerously cold, depending on the ambient conditions. Infants and pets can be injured or killed in such circumstances. Solutions have been proposed for generating alerts or causing air to circulate in a vehicle when an occupant is detected in a vehicle that is not running. However,
The present innovation overcomes the foregoing problems and other shortcomings, drawbacks, and challenges of vehicle occupant safety systems. While the present innovation will be described in connection with certain embodiments, it will be understood that the invention is not limited to these embodiments. To the contrary, this invention includes all alternatives, modifications, and equivalents as may be included within the spirit and scope of the present invention.
According to one aspect of the present innovation, a vehicle includes a heating, ventilation and air conditioning (HVAC) system that comprises and is managed by a climate control unit (CCU). The vehicle includes an engine that provides operative power to the ECM. The vehicle includes an ignition locking system (ILS) communicatively coupled to start and stop operation of the engine. The vehicle includes an electronic control module (ECM) that provides an operational status of the engine. The vehicle includes a passenger compartment that is maintained within a safe temperature range by the HVAC system. The vehicle includes power-locked doors that selectively allow access to the passenger compartment. The vehicle includes power-actuated windows that selectively allow external airflow into the passenger compartment. The vehicle includes a thermal injury prevention system having an occupant sensor, a temperature sensor, and a controller. The occupant sensor detects presence of a passenger in the passenger compartment. The temperature sensor detects a temperature within the passenger compartment. The controller is communicatively coupled to the CCU of the HVAC system, the ILS, the ECM, the power locked doors, the power-actuated windows, the occupant sensor, and the temperature sensor. The controller determines whether a thermal risk exists for an occupant of the passenger compartment based on: (i) identifying, via the temperature sensor, that the temperature within the passenger compartment is outside of a safe temperature range; (ii) identifying, via the ECM, that the engine is not running, and (iii) identifying, via the occupant sensor, that an occupant is in the passenger compartment. In response to determining that the thermal risk exists, the controller: (a) starts the engine via the ILS; (b) closes the power-actuated windows; (c) locks the power-locked doors; and (d) activates the HVAC via the CCU to maintain the temperature of the passenger compartment within the safe temperature range to safeguard the occupant until return of a responsible party.
According to one aspect of the present innovation, a thermal injury prevention (TIP) system includes an occupant sensor to detect presence of a passenger in a passenger compartment of a vehicle. The TIP system includes a temperature sensor to detect a temperature within the passenger compartment. The TIP system includes a HPM communicatively coupled to the occupant sensor and the temperature sensor and comprising a controller and one or more interfaces communicatively coupled to components of the vehicle. The components of the vehicle include an HVAC system that is managed by a CCU, an engine that provides operative power to the ECM, an ignition locking system (ILS) communicatively coupled to start and stop operation of the engine, an electronic control module (ECM) that provides an operational status of the engine, a passenger compartment that is maintained within a safe temperature range by the HVAC system, power-locked doors that selectively allow access to the passenger compartment, and power-actuated windows that selectively allow external airflow into the passenger compartment. The controller determines whether a thermal risk exists for an occupant of the passenger compartment based on: (i) identifying, via the temperature sensor, that the temperature within the passenger compartment is outside of a safe temperature range; (ii) identifying, via the ECM, that the engine is not running; and (iii) identifying, via the occupant sensor, that an occupant is in the passenger compartment. In response to determining that the thermal risk exists, the controller starts the engine via the ILS; closes the power-actuated windows; locks the power-locked doors; and activates the HVAC via the CCU to maintain the temperature of the passenger compartment within the safe temperature range to safeguard the occupant until return of a responsible party.
According to one aspect of the present innovation, a method includes determining whether a thermal risk exists for an occupant of a passenger compartment of a vehicle based on: (i) identifying, via a temperature sensor, that a temperature within the passenger compartment is outside of a safe temperature range; (ii) identifying, via an ECM of the vehicle, that an engine of the vehicle is not running; and (iii) identifying, via the occupant sensor, that an occupant is in the passenger compartment. In response to determining that the thermal risk exists, the method includes starting the engine via an ILS; closing power-actuated windows of the passenger compartment; locking power-locked doors of the passenger compartment; and activating an HVAC system of the vehicle via a CCU to maintain the temperature of the passenger compartment within the safe temperature range to safeguard the occupant until return of a responsible party.

According to aspects of the present disclosure, a vehicle, system, and method provide determining whether a thermal risk exists for an occupant of a passenger compartment of a vehicle based on: identifying, via the temperature sensor, that the temperature within the passenger compartment is outside of a safe temperature range, identifying, via an electronic control module, that an engine of the vehicle is not running, and identifying, via the occupant sensor, that an occupant is in the passenger compartment. In response to determining that the thermal risk exists, a controller starts starting the engine via an ignition locking system, closes power-actuated windows of the passenger compartment, locks power-locked doors of the passenger compartment, and activates a heating, ventilation and air conditioning system of the vehicle via a climate control unit. The HVAC maintains the temperature of the passenger compartment within the safe temperature range to safeguard the occupant until return of a responsible party.
