In this case, the changeover switch 10 is inserted between the power input terminal and the actuator 7, but the changeover switch 10 only needs to be connected in series with the actuator 7, and the changeover switch 10 should not be inserted between the actuator 7 and the ground.

FIG. 3 shows the processing procedure of the microcomputer 62. First, the rotation speed D of the internal combustion engine is detected (step S1), and it is determined whether the rotation speed is below a predetermined rotation speed corresponding to idling or trolling ( Step S2).

Subsequently, the voltage V of the capacitor 3 (see FIG. 7) is detected (step S3), and it is determined whether the voltage is below a predetermined voltage (step S4).

If the remaining amount of power stored in the power storage device 3 is sufficient, it is determined in step S4 that the voltage V is equal to or higher than the predetermined voltage. Therefore, the common contact 11 and the switching contact 12 in the switching circuit 64
The drive signal A calculated by the microcomputer 62 is applied to the actuator 7 as it is. For example, the drive signal A adjusts the energization time of the ignition coil, the amount of fuel injection, the air flow rate of the throttle, and the like.

して制限されることになる（ステップＳ５）。On the other hand, if it is determined in step S4 that the voltage V is less than the predetermined voltage, it is recognized that the remaining amount of stored electricity in the capacitor 3 is decreasing, so the microcomputer 62 Outputs a control signal C for limiting current consumption. As a result, the switching circuit 6
The changeover switch 10 in the switch 4 operates to bring the common contact 11 into conduction with the changeover contact 13, and the drive signal A is applied to the actuator 7 via the resistor 15. Therefore,
The current consumption of the actuator 7 due to the drive signal A is reduced and limited (step S5).

ができる。For example, if the actuator 7 subject to current consumption restriction is a fuel pump, the fuel injection amount will be reduced compared to normal, but when idling or trolling, there is sufficient margin for the required fuel, so No problem. Further, although the actuator 7 that particularly contributes to the current consumption is the fuel pump, the same effect can be achieved when the actuator is used as an ignition coil. As a result, the power consumption of the power storage device 3 is reduced, so that over-discharge of the power storage device 3 is prevented, and the system including the control circuit 6 can continue to operate.

In FIG. 4, 16 is a normally closed contact that shorts both ends of the resistor 15, and 17 is a normally closed contact 16 that is energized by the control signal C.
This is an excitation coil that opens the . In this case, the actuator 7 is inserted between the power input terminal and the resistor 15, but as described above, it may be inserted between the resistor 15 and the ground.

流が実質的に減少する。Furthermore, although the control signal C is a level inversion signal for switching, it may also be a pulse signal that repeatedly turns on and off. FIG. 5 shows an example in which a control signal C consisting of a pulse signal is used, and 18 is a transistor that is turned on and off by the control signal C. The collector of the transistor 18 is connected to the power input terminal and the actuator 7, and the emitter is grounded. In this case, when the control signal C is off, the normal drive signal A is applied to the actuator 7, and when the current is limited, the transistor 18 is turned on and off by the control signal C, so that the current consumption of the actuator 7 due to the drive signal A is substantially reduced. Decrease.

動作を保証することができなくなる。Furthermore, if the current consumption of the actuator 7 is limited when the voltage V of the capacitor 3 is determined to be below a predetermined voltage, but the voltage V does not recover and continues to decrease even after executing the current limiting step S5, Ultimately, it becomes impossible to guarantee the minimum operation of the internal combustion engine.

っても同様である。For example, if the resistor 15 is inserted into the drive signal A for the fuel pump when the voltage V is below the second predetermined voltage corresponding to the lower operating limit voltage, the current restriction will be too effective and the supplied fuel discharge amount will be reduced. The amount falls below the minimum operating requirement, and the internal combustion engine stops. Therefore, when the voltage V is below the guaranteed operation voltage, the current is limited, that is, the resistor 15
It is necessary to avoid the insertion of fuel and secure the fuel supply amount. This is true not only for fuel pumps but also for other actuators.

Note that the predetermined voltage range is the predetermined voltage used as the criterion in step S4 described above.

In the control circuit, the control circuit includes a rotation speed determining means for determining whether or not the rotation speed is a predetermined rotation speed or less, and a rotation speed determining means for determining whether the rotation speed is a predetermined rotation speed or less, and a rotation speed determining means for determining whether the rotation speed is a predetermined rotation speed or less and a rotation speed determining means for determining whether the rotation speed is a predetermined rotation speed or less. An internal combustion engine control device comprising: voltage determining means for determining whether the voltage is lower than a predetermined voltage; and current limiting means for reducing current consumption of the actuator by the drive signal when the voltage is equal to or lower than a predetermined voltage.
