<p>PROBLEM TO BE SOLVED: To test a vehicle system in real time through a simple arrangement. SOLUTION: A start signal representative of simulation start is transmitted from a GUI node to each node in response to a simulation start command (100, 102). Each node is initialized upon receiving the start signal and when initialization of all nodes is ended, a sync signal is transmitted to each node in order to synchronize a vehicle system test equipment (104, 106). Operation period t of each node, which is the greatest common measure of periods of one loop operation, is then detected based on the state from each node (110) and a communication period T, which is the greatest common measure of the operation period of respective nodes, is determined (112). Subsequently, a sync period V for operating the vehicle system test equipment while synchronizing is set (114) and real time processing is executed by a sync signal having a set sync period (116-124).</p> |
