Abstract
A multiple communication system used in an automobile includes miniaturized multi-function electric units. Each electric unit is composed of a CPU and a bus driver, and the CPU is connected to a bus line through the bus driver. The CPU of each of the electric units includes a communication processing program, and communication can be carried out among the electric units through the bus line using the communication processing program. Each CPU can be connected to its associated bus driver through only two data I/O ports. Thus, the number of I/O data ports is reduced as compared with the case in which conventional communication ICs are used. Further, since the bus drivers of small size are used, the electric units can be miniaturized. Further, the communication processing program of each CPU can be rewritten through the bus line.
