Description

  The present invention relates to an air conditioning control device, and more particularly to an air conditioning control device that performs air conditioning control in an electric vehicle such as an electric vehicle (EV) or a hybrid vehicle (HEV).

  Since electric vehicles such as EV (electric vehicle) vehicles and HEV (hybrid) vehicles prioritize vehicle travel when the remaining battery level decreases, restrictions on air conditioning equipment such as auxiliary heaters (PTC) and electric compressors are required. The When this air conditioner is restricted, heating and cooling are both in the lowest drive state (minimum (Min) power value for the electric compressor) and auxiliary heater is the minimum regardless of the vehicle running state and the power generation state (in the case of HEV vehicles). Therefore, even if the power required for the cooling and heating performance determined by the panel state operated by the occupant, the outside air temperature, etc. is different, the operation is uniformly restricted.

In other words, the air conditioning control as a result based on a rough judgment based only on affirmative / negative execution of power restriction is a simple restriction of the normal value of the drive control amount of the air conditioning control as the drive control amount at the time of restriction. Even in the state is done uniformly.
By the way, when the mode for selecting the jet outlet in the air conditioner is the defroster mode or the defroster & foot mode (D / F mode) that enhances the antifogging property (antifogging performance), moisture (water vapor) contained in the air is condensed. In order to increase the temperature of the air cooled by the cooling cycle system unit to the target ejection temperature, the heating device of the air conditioning unit is It is controlled to drive.

JP 1997-76740 A Japanese Patent No. 3791234

The hybrid vehicle according to Patent Document 1 performs cooling by sending electric power from a battery that supplies electric power to a driving electric motor to a cooling unit.
The air conditioner for a hybrid vehicle according to Patent Document 2 calculates the required air conditioning power required by the air conditioner unit to adjust the room to a set temperature, and the remaining battery capacity as the required air conditioning power increases during vehicle travel. Is set to a high target value.

However, conventionally, in the summer, when an auxiliary heater that is a heating device is not used and only an electric compressor that is a cooling device is required, it can be driven only with a minimum (Min) power value. However, the electric compressor is limited to the minimum (Min) electric power value even though the drive electric power can be added to the electric compressor side. In addition, there is a problem in that, for example, the operation of the air-conditioning apparatus is completely stopped even when the remaining amount of the battery is still present or when power generation is possible as in a hybrid (HEV) vehicle.
In the case of the defroster mode and the defroster & foot mode (D / F mode), it is necessary to drive the cooling device and the heating device at the same time, and both the cooling and heating systems require electric power. Power consumption increases. In addition, there is a possibility that the power consumed for the driving force of the vehicle may be instantaneously affected, and the cruising distance will be greatly reduced over a long period of time. Compared to high. Therefore, although it is easy to impair the substantial function due to the power limitation, the heat resistance is lowered when the function is not substantially limited due to the power limitation. From the viewpoint of ensuring visibility during traveling, there is an advantage in that it is desired to ensure that air conditioning performance is avoided while avoiding a decrease in heat resistance under specific conditions.
Further, in the air conditioning control as a result based on a rough judgment of only affirmation / denial of restriction execution, an air conditioning control that does not make a detailed judgment on the operating condition of the air conditioner and changes the power distribution based on the detailed judgment. Not done.
The cruising distance can be extended according to the amount of power consumed by the air conditioning, but even if the necessary power for the cruising distance is secured, the air conditioning control may significantly impair comfort. there were.

  Accordingly, an object of the present invention is to make a detailed determination of the operating conditions of the air conditioner, change the power distribution based on the detailed determination, etc., so as to further improve passenger comfort under air conditioning restrictions.

The amount of usable power of the heating device is calculated from the ratio, the target cooling power is calculated, and when the target cooling power is equal to or less than the amount of usable power of the cooling device, the amount of usable power of the cooling device and the target cooling The difference in power is set as a cooling device power difference, and the target cooling power is driven as a cooling drive limit value.When the target cooling power exceeds the usable power amount of the cooling device, the cooling device power difference is set to zero. When the cooling device is driven by using the cooling device drive power difference as the cooling device drive power difference between the cooling device usable electric energy and the heating appliance power, and the target heating power is equal to or less than the heating appliance usable power amount A difference between the usable electric energy of the heating appliance and the target heating power is set as the heating appliance power difference, and the target heating power is driven as a heating drive limit value. When the target heating power exceeds the usable electric energy of the heating appliance, the heating appliance power difference is set to zero, and the usable electric energy of the heating appliance and the cooling appliance power difference are driven as a heating drive limit value. It is characterized by that.

  The air conditioning control device according to the present invention makes efficient decisions such as making detailed judgments such as operating conditions of the air conditioning equipment and changing the power distribution based on the detailed judgment so as to further improve passenger comfort under air conditioning restrictions. Air conditioning control can be used to ensure both cruising distance and passenger comfort.
