Abstract:
1. An electronic control apparatus controlling a load connected thereto, the apparatus comprising: control means for controlling the load to be driven, outputting a predetermined judgment data at a predetermined timing; first judging means for judging based on the predetermined judgment data whether or not the control means has fallen into an abnormal state in which the load cannot be driven properly by the control means, and outputting a first judging signal used for having the load forcibly set to a predetermined idle state, the first judging signal being active when the control means is in the abnormal state; second judging means arranged separately from the first judging means, for judging whether or not the control means has fallen into an abnormal state in which the load cannot be driven properly by the control means, and outputting a second judging signal used for having the load forcibly set to a predetermined idle state, the second judging signal being active when the control means is in the abnormal state; and releasing means for releasing the first judging signal to be inactive, wherein the first judging means is adapted to keep the first judging signal active regardless of the judgment data from the control means once the first judging signal becomes active and to release the first judging signal to be inactive in response to the releasing means, the second judging means is adapted to keep the second judging signal active regardless of the judgment data from the control means once the second judging signal becomes active, the load being forcibly set to the idle state regardless of the control means while at least one of the first judging signal or the second judging signal is active.
