PROBLEM TO BE SOLVED: To prevent omission of a task while suppressing reduction of control performance.SOLUTION: An electronic controller comprises: storage means in which a task to be executed for every constant time, is stored; and processing means for executing the task for every constant time. In plural functions for forming the task, a first kind logic function which cannot be simplified, and a second kind logic function which has a less affection to control of a control target even when it is simplified, are contained. The storage means stores, as the second kind logic function, a normal logic function which is not simplified and a simple logic function which is simplified. As execution modes of the task, a normal logic mode (S150) for executing the normal logic function as the second kind logic function, and the simple logic mode (S160-S200) for executing the simple logic function, are provided. The processing means switches the execution mode from the normal logic mode to the simple logic mode, when it is determined that omission of the task may occur.SELECTED DRAWING: Figure 3 |
