COMMUNICATION CONTROL DEVICE

摘要

In an automobile-mounted network system for collecting pieces of information at dispersed positions in the automobile, a communication control device is provided for reducing the time difference between the information collection instants as much as possible. On a network (21) which is configured in the automobile, which can perform a broadcast and which is realized in a communication mode which is periodically given a transmitting right, the communication control device holds in a sensor data holding register (49) the information on a measurement result of a sensor (23) at the instant when a predetermined time period elapses after it received a periodically transmitted specific signal, and transmits the information at the instant when the transmitting right is attained on the network (21).
