源の供給を断続できるようになっている。The electric auxiliary machine 1 is an electromagnetic modulator for brake fluid pressure control, and the electric auxiliary machine 1 is an electromagnetic modulator for controlling brake fluid pressure.
Anti-lock control is now available for Norki. The central control device is provided with a detection means 2 that outputs a notification to the outside when the electric auxiliary machine is energized. The signal line of this detection means 2 is connected to relays 5a and 5b, which are opening/closing means 5. These relays 5a and 5b are connected to a battery as a main power source 3, and a car air conditioner 4a and a car air conditioner as a vehicle electrical equipment 4.
and the car stereo 4b, respectively, so that the power supply can be interrupted and interrupted.

を閉。The operation will be explained below with reference to FIG. First 1. The process starts in step 50, and in step 51 it is determined whether or not electric power is supplied to the electric auxiliary machine 1. If not, the process returns to step 51 via the negative column. On the other hand, the affirmative column moves to step 52 and opens [Month No. 5], that is, the power is turned off. Next, the process moves to step 53, and it is determined whether or not the power supply to the 5 electric auxiliary machine 1 is terminated.If the 5 is negative, the process returns to step 53, and if the 5 is affirmative, the relay 5 is turned off in step 54.
Close.

冷蔵庫も対象となるのはもちろんである。Note that when performing the above power control control on a car stereo, it is best to cut off the power supply only to the amplifier section, which consumes a lot of power, and leave the tape drive section, which consumes less power, to continue operating. It is desirable to be able to prevent damage. Further, as the vehicle electrical equipment 4, it goes without saying that the rear window defogger and the in-vehicle refrigerator, which have no effect on safety in case of a momentary power outage, are also targeted.
