Vehicle air conditioning system and air conditioner control method
A vehicle air conditioning system, including: a vehicle interior environmental information acquisition unit that acquires environmental information of a vehicle interior; a vehicle exterior environmental information acquisition unit that acquires environmental information of surroundings of the vehicle; a sensible temperature prediction unit that predicts a sensible temperature of an occupant of the vehicle after a predetermined amount of time has elapsed, based on the environmental information acquired by the vehicle cabin interior environmental information acquisition unit and the vehicle cabin exterior environmental information acquisition unit; and an air conditioner controller that controls an air conditioner based on information regarding a future sensible temperature of the occupant which has been predicted by the sensible temperature prediction unit and a comfortable sensible temperature of the occupant which is stored in a storage unit.
1. A vehicle air conditioning system, comprising:
a memory; and
a processor coupled to the memory, the processor is configured to:
acquire environmental information of an interior of a vehicle;
acquire environmental information of surroundings of the vehicle;
acquire information of a setting temperature of a seat heater;
predict a sensible temperature of an occupant of the vehicle after a predetermined amount of time has elapsed, based on the acquired environmental information of the interior of the vehicle, the acquired environmental information of surroundings of the vehicle, and the acquired information of the setting temperature of the seat heater; and
control an air conditioner based on information regarding the predicted sensible temperature of the occupant and a comfortable sensible temperature of the occupant which is stored in a storage unit.
2. The vehicle air conditioning system according to claim 1 , wherein the processor is configured to:
acquire information of at least one of an amount of clothing of the occupant or a metabolic rate of the occupant; and
predict the sensible temperature of the occupant after the predetermined amount of time has elapsed, based on the acquired information of the at least one of the amount of clothing of the occupant or the metabolic rate of the occupant.
3. The vehicle air conditioning system according to claim 1 , wherein the processor is configured to acquire information of at least one of an air temperature outside the vehicle, an amount of solar radiation, or information indicating time and location of the vehicle; and
predict the sensible temperature of the occupant after the predetermined amount of time has elapsed, based on the acquired information of the at least one of the air temperature outside the vehicle, the amount of solar radiation, or the information indicating time and location of the vehicle.
4. The vehicle air conditioning system according to claim 1 , wherein the processor is configured to acquire information of at least one of a temperature of the interior of the vehicle, an air conditioning setting temperature, a state of air inside and outside the vehicle, an air conditioning air flow, a state of an outlet, a humidity of the interior of the vehicle, or an open/closed state of a window; and
predict the sensible temperature of the occupant after the predetermined amount of time has elapsed, based on the acquired information of the at least one of the temperature of the interior of the vehicle, the air conditioning setting temperature, the state of air inside and outside the vehicle, the air conditioning air flow, the state of the outlet, the humidity of the interior of the vehicle, or the open/closed state of the window.
5. The vehicle air conditioning system according to claim 1 , wherein the processor is configured to predict the sensible temperature of the occupant after the predetermined amount of time has elapsed, based on a body color of the vehicle, a color of side glass of the vehicle, and whether or not the vehicle has a sunroof.
6. An air conditioner control method comprising:
acquiring, by a processor, environmental information of an interior of a vehicle;
acquiring, by a processor, environmental information of surroundings of the vehicle;
acquiring, by a processor, information of a setting temperature of a seat heater;
predicting, by a processor, a sensible temperature of an occupant of the vehicle after a predetermined amount of time has elapsed, based on the acquired environmental information of the interior of the vehicle and the acquired environmental information of the surroundings of the vehicle; and
controlling, by a processor, an air conditioner based on information regarding the predicted sensible temperature of the occupant, a comfortable sensible temperature of the occupant which is stored in a storage unit, and the acquired information of the setting temperature of the seat heater.
