Claim One:
1. An apparatus for calculating a temperature of a conductive carrier of a catalyst converter for cleaning an exhaust emission out of an internal combustion engine, the conductive carrier carrying a catalyst of the catalyst converter, the conductive carrier being energized for warm of the catalyst, the apparatus comprising: a temperature obtainer to obtain, in a learning mode of the apparatus during the conductive carrier being deenergized, at least one value of the temperature of the conductive carrier based on a physical parameter correlative with the temperature of the conductive carrier and different from a resistance of the conductive carrier; a resistance obtainer to instantaneously energize, in the learning mode, the conductive carrier to obtain at least one value of the resistance of the conductive carrier during the instant energization; and a calculator to obtain, in a normal operation mode of the apparatus after the learning mode, a value of the resistance of the conductive carrier, and calculate, in the normal operation mode, a value of the temperature of the conductive carrier based on: the obtained value of the resistance of the conductive carrier, and a pair of the at least one value of the temperature of the conductive carrier and the at least one value of the resistance of the conductive carrier obtained in the learning mode.
