PURPOSE:To prevent an air conditioner from cooling down and maintain comfortableness inside a vehicle by interrupting the air conditioner while the vehicle is being halted with a transmission gear staying in a shift position of a drive range and a fan is running at a low speed. CONSTITUTION:If the shift position is in a drive range and a vehicle is put into a stop condition with a fan running at a low speed, a shift position detecting means 4 detects the drive range and generates a drive range signal 4a and a fan revolving speed detecting means 11, at the same time, detects the low revolution of the fan and generates a low revolution signal 11a. In a discriminating means 10 a switch means 12 is turned on because the discriminating means detects a car speed of zero from the output of a car speed sensor 7 and an OR circuit 13 generates an output of 1 because of the output from the foot-operated or parking brake sensor 8 or 9 so that a NAND circuit 14 exhibits an output of 0. Receiving an interruption signal 10a of the discriminating means 10, a control means 2 interrupts an air conditioner 1. |
