Conventionally, it has been considered that automotive loads are controlled by control circuits consisting of microcomputers, and in particular loads that can only operate when the ignition switch is on, such as wiper motors or turn signal lamps. When controlling the ignition switch, an on-signal generation circuit is provided that outputs an ignition-on signal when the ignition switch is on, and a command signal generation circuit that outputs a command signal in response to the on-operation of a wiper switch, turn switch, etc. It is conceivable that a circuit is provided, and the control circuit is configured to control the operation of the corresponding load based on the command signal on the condition that the ignition-on signal is output. By the way, in such a configuration, if a failure occurs such as the transmission path of the ignition-on signal formed on the printed wiring board being disconnected, and the ignition-on signal is no longer output normally. for,
Loads such as wiper motors, turn signal lamps, etc., which are essential for safe driving of the automobile, become inoperable. However, in this case, all other functions are in a normal state, so there is a risk that the driver may continue driving the vehicle without realizing that the load essential for safe driving has fallen into an inoperable state as described above. However, the reliability of control by the control circuit is low, and this point has remained an unresolved issue.

る。 In FIG. 2, only a portion of the control program stored in the control circuit 8 that is related to the gist of the present invention is shown in the form of a flowchart, which will be explained below. That is, in the judgment step (a), it is judged whether "ignition on signal S5 is present or not", and if "YES", the "load control routine" is executed.
(b) Return to the start address via a routine not shown. In the above-mentioned "load control routine" (b), the wiper motor 1 and turn signal lamp 3 are energized and driven based on the command signals S 2 and S 4 . In addition, when it is determined "NO" in the judgment step (a), that is, when the ignition on signal S5 is not input, the process moves to the judgment step (c) and the "running signal
If the answer is "NO", the "load control routine" (b) is skipped. Therefore,
In a state where neither the ignition on signal S5 nor the travel signal S6 are output, the wiper motor 1 and turn signal lamp 3 are not energized even if the wiper switch and turn switch are turned on. On the other hand, when it is determined as "YES" in the judgment step (c), that is, when the running signal S6 is input without the ignition on signal S5 being input, the alarm 7 is energized and driven. Occurrence” process
After passing through (d), the process moves to the "load control routine" (b). As a result, when the running signal S6 is output even when the ignition-on signal S5 is not output (i.e., when the vehicle is in a running state)
The wiper motor 1 and the turn signal lamp 3 can be operated in accordance with the operation of the wiper switch and turn switch. Therefore, even if a failure occurs such as disconnection of the transmission line for the ignition-on signal S5 , the wiper motor 1 and turn signal lamp 3, which are essential for safe driving, can continue to operate as before when the vehicle is running. A so-called fail-safe function can be obtained, and the reliability of control by the control circuit 8 can be improved. Furthermore, in this case, the occurrence of a failure is notified in response to activation of the alarm device 7, so that the failure can be dealt with quickly.
