Abstract: An in-vehicle radiant heater control apparatus includes: a temperature detection device for a heater in a vehicle compartment; a first switch element connected in series to the radiant heater between a power supply and a ground; a temperature control device controlling the first switch element that the heater temperature approaches a target temperature; a resistive element having one electrode connected to one electrode of the heater; an inter-electrode voltage detection device for the resistive element; and a resistance calculation device repeatedly obtaining a heater resistance of the radiant heater based on a voltage between the other electrode of the resistive element and the other electrode of the heater, a detected resistance voltage, and a resistance of the resistive element. The temperature detection device obtains the heater temperature based on the heater resistance.
