Abstract

PURPOSE:To enable the accurate time of temperature rise to be determined despite the presence of an earth resistor by supplying a constant current only to a heater resistor while battery voltage to the heater resistor and a current limiting resistor so as to calculate the present heater temperature and heater resistance value. CONSTITUTION:A heater resistor RH preheating intake, current limiting resistor RD connected to and separated from the heater resistor RH by a three-position switch S and a controller 1 grounded to a car body providing a built-in constant- current regulated power source 2 are respectively provided. While supplying a constant current from the constant-current regulated power source 2 only to the heater resistor RH with the three-position switch S controlled by the controller 1, voltage from a battery Ba is supplied respectively to the heater resistor RH and the current limiting resistor RD. While the controller 1 respectively calculates the present heater temperature and the value of an earth resistor RG connected to the heater resistor RH. By the control thus obtained, the heater resistor RH is heated by obtaining the time of rapid temperature rise for reaching the target temperature.
