<p>PURPOSE: To provide a method and device for obtaining the time synchronization of information transmitted between the devices of a bus type network. CONSTITUTION: A first network transmits a first message uniquely identified as a synchronizing message to a second network. When the first message is transmitted, a first relative time is obtained in the first network. When the first network recognizes that the first message is transmitted, a second message including the real time of the first network when the first message is transmitted is transmitted to the second network. The second network obtains a third relative time in the second network when the first message is received. The real time of the first network included in the second message is related with the third relative time of the second network so that the time of the second network can be synchronized with the time of the first network.</p> |
