<p>PURPOSE:To allow the system to cope with flexibly various communication systems by devising an input output control means of a central control means to execute various communication protocols. CONSTITUTION:A central control means LANC/U1 of a communication system in an automobile uses all communication protocols 103-105 to manage all information by a CPU 101 centralizingly. The actuator control by LCU 300-303 is executed by a communication protocol 103 for a low speed class A and a CPU is provided for an engine C/U 200 and an automatic transmission C/U 201 or the like respectively for a high speed class C and various arithmetic operation is executed based on the information of the communication protocol of the class C to activate actuators 500, 503. Otherwise the IO processor 102 applies parallel processing to communication protocols in the inside of the LANC/U1. Thus, the transmission reception and processing of data are executed efficiently even to a terminal equipment processing means whose processing speed differs.</p> |
