<p>PURPOSE:To enable high-speed data communication without the generation of erroneous data and noise in the multiple communication equipment for on- vehicle signal communication. CONSTITUTION:By contention system, data are transferred from nodes 12-14 through a communication bus 11. In the system, data transmission frame consists of at least a first and second data sections and a communication speed variable means (consisting of 4-bit counters 15 and 16 and logical circuits 17 and 18 or the like) capable of varying the data communication speed is provided to make the communication speed of the second data section located at the back part higher than that of the first data section located on the front of the transmission frame and having the identifier with the priority.</p> |
