VEHICLE AIR CONDITIONING CONTROL DEVICE

摘要

A vehicle air conditioning control device calculates, through a thermal load calculating unit, a vehicle interior thermal load Q on the basis of, for example, a vehicle interior temperature Tin, a vehicle interior humidity Hin, a vehicle exterior temperature Tout, a passenger load factor θ, and a vehicle-interior-temperature set value Tset. Through an air conditioning output calculating unit, the vehicle air conditioning control device calculates an output command value for an air conditioner on the basis of a vehicle-interior-temperature upper-limit value Tmax, a vehicle-interior-temperature lower-limit value Tmin, the thermal load Q, power-running/regenerative electric power P, and then, corrects the calculated output command value for the air conditioner on the basis of power-running/regenerative electric power Pf at or after a prediction time point and of a passenger load factor Of at or after the prediction time point.
