Abstract
A centralized electrical equipment control system controls the electrical equipment of a vehicle and provides the capability of reducing the manufacturing cost while facilitating the modification and development of the electrical system of the vehicle. The electrical equipment control system has a central control unit including a microcomputer and a communication circuit. The microcomputer exchanges data through the communication circuit via a communication network with respective communication circuits of an ignition I/O unit, a meter I/O unit and a flasher I/O unit to control the I/O units. The electrical equipment control system utilizes only a single microcomputer and a simple I/O port and is thus capable of reducing the manufacturing costs of the electrical equipment.
