Abstract

PURPOSE:To facilitate checking of vehicle interior temperature by a method wherein there are provided an indicator for indicating the interior temperature in accordance with a temperature scale of a temperature instruction unit and a lighting control circuit for lighting that portion of the indicator which corresponds to the interior temperature in accordance with the output of an interior temperature sensor. CONSTITUTION:For example, when vehicle interior temperature as indicated on a temperature indicator 4 is between light-emitting diodes L2 and L3 and a temperature setting lever 5 is set between light-emitting diodes L6 and L7, there are established relationships Vi<Vs, V2<Vi<V3 and V6<Vs<V7, with each of Vs1-Vs9 equals to 0, where Vi is the output voltage of an interior temperature sensor 1, V1-V9 the reference voltage of comparators As1-As9 in a lighting control circuit 3, Vs1-Vs9 the contact voltages determined by a change-over switch 2b of a set- temperature sensor 2, and Vs the output voltage of the sensor 2. Therefore, the diodes L3-L6 are caused to emit light through the comparators As1-As9 and various kinds of gates B1-B9, C1-C9, D1-D9.
