A thermal request mediating device includes a calculation unit configured to calculate amounts of heat for thermal circuits, a mediation unit configured to determine amounts of absorbed heat or amounts of discharged heat which are allocated to the thermal circuits based on amounts of heat transferable between the thermal circuits, and a distribution unit configured to distribute amounts of absorbed heat or amounts of discharged heat to units which are included in each thermal circuit based on the determined amounts of absorbed heat or amounts of discharged heat.

In an air-outlet unit that forms an air outlet of an air conditioner in an automobile, a light-emission control unit controls, in accordance with the airflow rate of the air conditioner that is obtained from an air-conditioning control device of the automobile, an LED driving unit that drives an LED array in such a manner that the amount of light that is emitted from the LED array and that activates a photocatalytic filter increases as the airflow rate of the air conditioner increases. The light that is emitted from the LED array is visible light, and some of the light that is reflected by the photocatalytic filter transmits to an area outside of the air-outlet unit by passing through fins that adjust the direction and the flow rate of the air blown by the air-outlet unit.

A computer-implemented process for controlling a vehicle interior includes detecting a previously defined situation that relates to an undesirable environmental condition of the vehicle interior, and assessing both a risk level and an urgency level, based on a vehicle sensor input. The process also includes generating a vehicle command based upon the detected previously defined situation, the assessed risk level, and assessed urgency level, and executing the generated vehicle command to control at least one of an engine, a window, and a heating, ventilation and air conditioning (HVAC) unit to modify an environmental condition of the vehicle interior.

A transport climate control system is described which comprises a controller configured to determine a power demand of a climate control circuit of the system and to provide power to the climate control circuit in a first power mode when the power demand is above a power threshold and to provide power to the climate control circuit in a second power mode when the power demand is at or below the power threshold. In the first power mode, power is provided from a prime mover and, in the second power mode, power is provided from an energy storage source and not the prime mover. Corresponding methods for controlling a transport climate control system are also described.

This disclosure describes systems and methods for limiting the functionality of remote start systems within vehicles. Remote start operations may be limited, for example, in response to exceeding one or more remote start limits. Limiting the remote start operations may include either preventing the initiation of a remote start request or ending an already in-progress remote start operation.

A method for controlling heating of a hybrid vehicle is provided. The vehicle includes a duct flowing air into the indoor of the hybrid vehicle from the outside, a heater core for circulating the coolant heated from an engine inside the duct, a PTC heater heated by the power supplied from a high-voltage battery of the hybrid vehicle inside the duct, and a controller. The controller operates the engine and the PTC heater and heats the air flowing into the indoor of the hybrid vehicle through the duct. The voltage supplied to the PTC heater from a low voltage DC-DC converter (LDC) is changed based on the state of the engine and an auxiliary battery for supplying power to an electric component of the vehicle to apply power to the PTC heater.

A vehicular heat management system includes a refrigerant circulation line configured to cool or heat a passenger compartment by generating a hot air or a cold air depending on a flow direction of a refrigerant, a cooling water circulation line configured to heat the passenger compartment with waste heat of an engine by allowing cooling water of the engine to circulate through a heater core, a refrigerant-cooling water heat exchanger disposed in the cooling water circulation line to allow the refrigerant and the cooling water to exchange heat, and an engine cooling water independent circulation unit configured to allow the cooling water passed through the engine to bypass the heater core and the refrigerant-cooling water heat exchanger.

A computer includes a processor and a memory storing instructions executable by the processor to receive data indicating that an electric vehicle is in an enclosed space; in response to receiving the data, instruct window actuators of the electric vehicle to open windows of the electric vehicle; and in response to receiving the data, instruct a heater of the electric vehicle to generate heat.

Disclosed embodiments include apparatuses, vehicles, machines, equipment, and methods for selectively allocating airflow between different heat exchangers. In an illustrative embodiment, an apparatus includes a first heat exchanger configured to dissipate heat from at least one first system. A second heat exchanger is configured to dissipate heat from at least one second system. An airflow controller is configured to receive an intake airflow and to direct an output airflow to selectively direct at least a portion of the output airflow to either or both of the first and second heat exchangers.
