Abstract
PURPOSE: To minimize power consumption by shutting off all the power source to the lower processing unit (LPU) and the apparatus connected with LPU when the car stops.
CONSTITUTION: When the ignition key 4 and all the operation switches 5 are open when the car stops, it is detected by the switch-condition detecting device which is mounted on a part of the central processing unit (CPU) and the power switch on the power feeding rout 1 which is connected to LPU from the power source is turned off. Then, when one of the switches is turned on to start driving, it is detected by the switch-condition detecting device and the power switch is thrown in right away.
