Abstract: An engine compartment fire suppression system for an HVAC system of a vehicle monitors conditions including, but not limited to, a collision sensor, an air conditioning system pressure sensor, engine coolant temperature, exhaust gas temperature, or an engine load calculation. The fire suppression system discharges a fire suppression composition when a controller receives a specified combination of the monitored conditions.

Abstract: An automotive vehicle air extraction system in fluid communication with a cabin of the vehicle is provided. The extraction system may have a housing arrangement and a pair of extractors attached to the housing arrangement. A chamber may be formed between the housing arrangement and pair of extractors. An air pump may be in fluid communication with the chamber. The pair of extractors may be an inner extractor and an outer extractor. A controller may be configured to activate the air pump to supply airflow to the chamber to close the inner extractor and/or prevent inadvertent opening of the inner extractor.

Abstract: A vehicle climate control system is provided. The vehicle climate control system allows an occupant in the rear area of a vehicle to control the climate settings in the vehicle. It comprises a front climate interface, a rear climate interface, and a controller. When actuated, the controller disables the front climate interface and allows the rear climate interface to determine the climate settings. The controller is also operative to selectively restart a vehicle engine in order to reduce fuel consumption. The vehicle climate control system may be disabled when the engine is off and selectively enabled when the engine is operating.

Abstract: A system may include a multi-position airflow floor control. The system may further include a climate controller device configured to identify an airflow biasing promoting vehicle occupant comfort by performing operations including: determining by a climate controller of a vehicle, to perform cooling based on cabin temperature exceeding a temperature set-point; identifying an airflow biasing between at least a panel vent and a multi-position airflow floor control based on the cabin temperature and a plurality of set-point offsets; and providing an output to adjust cooling flow between at least the panel vent and the multi-position airflow floor control based on the identified biasing.

Abstract: An air duct assembly having a housing and a flexible vane. Sufficient airflow through the housing may actuate the flexible vane to permit airflow through an outlet.

Abstract: A blower assembly including a housing for a first scroll fan and a second scroll fan that are connected by a shaft to a motor that rotates the fans. The first and second scroll fans are coaxially mounted on the shaft. Fresh air ports and recirculated air ports are provided for the circulation of fresh air and recirculated air, respectively. The fresh air ports and recirculated air ports may be selectively opened and closed by doors to control the flow of air from the outside and from the passenger compartment as controlled by the HVAC system.

Abstract: A vehicle air circulating system comprises a controller, an interior condition sensor attached to the controller, an instrument panel, and a deployable register assembly attached to the controller and pivotably attached to the instrument panel. The register assembly includes a first register and a second register and is movable between a closed position in which the first register is recessed within the instrument panel and is thus obstructed and an open position in which the first register is deployed. The second register remains unobstructed whether the register assembly is in its closed or open position. The deployable registers provide directional control for pull down conditions. Once the desired conditions are achieved, the deployable registers lower into the instrument panel and the other registers provide a larger opening to direct the air overhead at lower velocities keeping the vehicle cabin cool while not blowing in the direction of the occupants.

Abstract: A system may control demist flow by computing a fogging possibility for a zone of a vehicle using a fogging heuristic according to received inputs, the fogging possibility indicative of fogging risk for vehicle glass in the zone of the vehicle; determining, based on comparing the fogging possibility to at least one fogging risk threshold, whether a change in demist flow for the zone is warranted to at least one of reduce the fogging risk for vehicle glass in the zone of the vehicle and reduce energy usage for the production of demist flow to be provided to vehicle glass in the zone of the vehicle; and selectively providing an output to at least one of the plurality of demist doors associated with the zone of the vehicle to adjust the demist flow to the zone of the vehicle when a change in demist flow for the zone is warranted.

Abstract: A system and method of controlling ventilation of a passenger compartment of a vehicle. An intake vent may be opened to allow ambient air to enter the passenger compartment and an exhaust vent may be opened to allow cabin air to exit the passenger compartment when the cabin air temperature is greater than the adjusted ambient air temperature value and a precipitation condition is not present.

Abstract: A climate control duct architecture having articulated and controlled interior surfaces to deliver variable and controllable airflow to target zones in the vehicle upon demand. By creating zone climates within the vehicle and providing conditioned airflow to only desired vehicle seating positions, the volume of necessary airflow is minimized, the need for cooling is reduced, and flexibility of the system is created. The interior surface may be mechanically or electrically controlled and may be situated in the common central “octopus” duct.
