Abstract
A multiple transmission system for use in a vehicle, in which a second node having a control function sends an command to first nodes of an ordinary type when an transmission error higher than a certain level takes place or at certain time intervals to effect system refreshment which resides in the following operation. Each of the first nodes, which has received the command, sends its status information (e.g., the status of an input device element such as a sensor or switch) to the other nodes. The other nodes which receive this information initialize their status (e.g., the status of an output device element such as an actuator or a motor) according to the received status information.
