The Harness has increased according to the increment of the automobile electronic control system. The decrement of harness will have been needed. Recently, it has been achieved using the thinned wire and small connector. But, it is not the basic solution to decrease the harness. The basic solution is to use the multiplexed wiring harness system. It is divided into the distributed control and central control.
This paper describes the central control that is method that master controls the each slave. The serial communication is used in the central control to transfer the data between the master and slave, but may result to the difficulty of the power control. It will be solved using the ring type power control proposed in this paper. The experimental results show that the object of the central control that decrement of the wiring harness is achieved, and the performance of the central control more improved using the ring type power control.
