A heater core for performing heat exchange between a coolant and ventilation air to be blown to the interior of a vehicle so as to heat the ventilation air is disposed in a water circulation circuit for circulating a coolant in an engine EG for outputting driving force necessary to move the vehicle. When the temperature of the coolant discharged from the engine EG is low, a heat transport refrigeration cycle device, serving as a heat transport unit for absorbing heat from a downstream coolant at a position downstream more than the heater core and dissipating the heat absorbed from the downstream coolant to an upstream coolant at a position upstream more than the heater core, is operated to increase the temperature of the coolant introduced into the heater core until the temperature of the coolant reaches the temperature necessary to heat the interior of the vehicle, without operation of the engine EG.

Disclosed are a vehicle control apparatus and a vehicle control method. The vehicle control apparatus may calculate a total sum of consumed power according to at least one of power consumed due to an air resistance, power consumed due to an operation of a cooling fan that increases flow of air introduced into an under-hood of a vehicle, or power consumed due to an operation of an air conditioner, or any combination thereof, and control at least one of an air flap that opens and closes an air inlet of the under-hood or a cooling fan, or any combination thereof such that the total sum of the consumed power is minimized in response to securing of a target air flow rate representing a flow rate of air required to pass through a condenser or a radiator of the air conditioner according to an operation of the vehicle.

The second area includes the second refrigeration component and the second heating component.

A system for determining an identification of an occupant within a vehicle can include a processor, a communications interface, and a memory. The memory can store an information reception module, an identification prediction module, and an actuation module. The information reception module can cause the processor to receive, via the communications interface, from at least one sensor, and at a time when a source of a propulsion force for the vehicle is in an off state, at least one signal having information about at least one detectable characteristic associated with the occupant within the vehicle. The identification prediction module can cause the processor to produce, based on the information, a prediction of the identification of the occupant. The actuation module can cause the processor to cause, in response to a production of the prediction, a setting of a component of the vehicle to have a specific value.
