<P>PROBLEM TO BE SOLVED: To provide an air conditioner controller of a vehicle by which the control of the shut-off of an air conditioner is performed by exactly detecting the state of a brake booster utilizing a sensor already installed at the vehicle, and the comfortability of an occupant can be secured by suppressing a frequency of the shut-off of the air conditioner to the minimum. <P>SOLUTION: The air conditioner controller of the vehicle includes a brake booster 2 reducing stepping an operation force of a brake by utilizing the air in-take negative pressure of an internal combustion engine 1, and an air conditioner 3 having a compressor driven by the internal combustion engine 1, and the air conditioner controller further includes: a hydraulic pressure sensor 19 detecting the hydraulic pressure of a master cylinder 10 of a brake device 12; a G sensor 23 detecting a wheel speed sensor 22 detecting the rotation speed of the wheel or the deceleration speed of the wheel; and an ECU (control means) 4 which stops the driving of the compressor of the air conditioner 3 when the deceleration speed of the vehicle detected by the wheel speed sensor 22 or the G sensor 23 is lower than a previously determined threshold with respect to hydraulic pressure detected by the hydraulic pressure sensor 19. <P>COPYRIGHT: (C)2012,JPO&INPIT |
