That is, in the conventional vehicle air conditioner, as shown in FIG. 12, the electric power input from the pantograph 31 is applied to the auxiliary power supply device 32, where an air conditioning power source is generated and the air conditioner 1 It is supplied to the heater 2 for heating. The air conditioning controller 3 controls the number of operating air conditioning compressors in the air conditioner 1, the operating frequency, the operating time, or controls the operating speed of the motor of the indoor blower to control the air conditioning capacity during the cooling operation. The air conditioning capacity control during heating operation is performed by controlling the heater 2 on and off at regular intervals.

  The air conditioning controller 3 is equipped with a microcomputer, and various corrections are performed on the air conditioning set temperature stored in the storage area, and the air conditioning reference temperature is sequentially calculated. The various corrections are provided inside the vehicle, the inside temperature measured by the inside temperature sensor 4 provided inside the vehicle, the outside temperature measured by the outside temperature sensor 6 provided outside the vehicle, and the inside of the vehicle. It is calculated based on the in-vehicle humidity measured by the in-vehicle humidity sensor 5 and the occupancy rate of the vehicle measured by the variable load sensor 7 provided in the vehicle.

Conventionally, the boarding rate is used for correction by measuring the boarding rate when the vehicle is traveling. In addition, there is a storage unit that stores the inter-station boarding rate information for each time zone that is created in advance based on the results, by day of the week, by month, day, by vehicle operation mode, and by vehicle. (For example, refer to Patent Document 1).
Furthermore, there is one that controls the air conditioning capability based on the air conditioning load predicted based on the current environmental information and the environmental information stored in the past (see, for example, Patent Document 2).
Further, there is one that periodically transmits data having air conditioner operation information and vehicle position information to the management computer, and the management computer stores and processes the data (see, for example, Patent Document 3). ).
