PROBLEM TO BE SOLVED: To provide an electronic control device capable of effectively reducing a failure possibility of the whole electronic control device when the functional safety of a high level is required.SOLUTION: An H/VECU 11 inputs a command signal, and includes an edge detection circuit 28 and a level detection circuit 29 as an input circuit for detecting a change of the level. In this way, the input circuit is duplicated, and therefore, a failure possibility of the input circuit can be reduced. Further, the failure possibility of the whole H/VECU 11 can be reduced. In addition, since the edge detection circuits 28 and the level detection circuits 29 of a plurality of kinds are provided as the input circuit, even when the mode of a change of the command signal is not normal, the possibility of detecting a change of the command signal can be enhanced so as to contribute the improvement of the functional safety.SELECTED DRAWING: Figure 2 |
