Abstract: A vehicle air conditioning control system includes an electric heater, a direct-current-to-direct-current converter, an engine system temperature sensor, and a controller. The electric heater applies heat to an air conditioning airflow. The direct-current-to-direct-current converter converts a voltage of electric power of an in-vehicle battery. The engine system temperature sensor measures a temperature of one or each of an engine and a related member. The controller controls an operating state of the electric heater based on the temperature. Upon determining, based on the temperature, that the electric heater is to operate, the controller performs a control of switching the operating state between: an operating state where the electric heater is turned on and the direct-current-to-direct-current converter is caused to output a short-time current; and an operating state where the electric heater is turned off and the direct-current-to-direct-current converter is caused to output a steady-state current.
