<p><P>PROBLEM TO BE SOLVED: To provide an on-vehicle device stably operated by processing tasks irrespective of priority without changing or increasing the performance of hardware such as a processing means. <P>SOLUTION: A processing interruption part 22 interrupts the tasks meeting the requirements for interruption among a plurality of tasks under operation irrespective of the priority of the tasks when the execution of the plurality of tasks by the processing part 13 exceeds the processing capacity of the processing part 13. The requirements for interruption are set as a requirement table including the requirements for interruption beforehand. The processing interruption part 22 interrupts the tasks related to the overlapped functions irrespective of the priority of the tasks according to the requirements for interruption. As a result, though a part of the tasks is temporarily interrupted and a part of the functions of the on-vehicle device 10 is restricted, the change of hardware such as an increase in the processing speed and clock frequency of the processing part 13 is not needed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
