Abstract:
1. A vehicular heating control system comprising: a fuel consumption reduction amount acquiring unit that acquires a fuel consumption reduction amount in an operating mode accompanied by an engine shutdown; a fuel consumption amount acquiring unit for acquiring a fuel consumption amount corresponding to electric power consumption during heating by an electrothermal heater that heats a vehicle cabin interior with heat resulting from an electric power supply and that is disposed separately from a heating unit, which heats the vehicle cabin interior using engine cooling water as a heat source during heating; a determining unit that determines whether there exists a fuel economy improving state when the fuel consumption amount that has been acquired by the fuel consumption amount acquiring unit is less than the fuel consumption reduction amount that has been acquired by the fuel consumption reduction amount acquiring unit; and a control unit that controls heating by the electrothermal heater when it has been determined by the determining unit whether there exists a fuel economy improving state.
