It is characterized by comprising a shut-off means for shutting off.

The control means in the external indicator lamp lighting system for a vehicle according to the present invention compares the level of the voltage corresponding to the rotational speed of the crankshaft with the reference voltage corresponding to the rotational speed of the crankshaft in which the vehicle does not travel, and compares the levels. It is characterized by further comprising rotation speed comparison means for stopping ignition during a lighting instruction period by the lighting instruction means when the voltage exceeds the reference voltage.

[0007]

According to the vehicle external indicator lamp lighting system of the present invention, the external indicator lamp is turned on during the period in which the lighting instruction means is lit and displayed. This lighting is done by the output voltage of the alternator. Therefore, the battery is not consumed. Furthermore, during the lighting instruction period, the ignition device controls the rotation speed of the crankshaft to a predetermined rotation speed at which the vehicle does not run under the control of the control means. As a result, the vehicle does not run. In addition, the ignition switch circuit is cut off by the cutoff means during the lighting instruction period. As a result, there is no problem even if the ignition switch is pulled out, and there is no risk of the vehicle being stolen.

EXAMPLES The present invention will be described below with reference to examples.

FIG. 1 is a circuit diagram showing a configuration of an embodiment of the present invention, and FIG. 2 is an external view of a delivery vehicle to which the present embodiment is applied.

In this embodiment, the output voltage of the AC generator 1 is full-wave rectified by the diodes 2 and 3, and the rectified output by the diodes 2 and 3 is supplied to the series circuit of the capacitor 4 and the primary coil of the ignition coil 5. Then, the capacitor 4 is charged with the rectified output, and the output from the pulsar 6 is supplied to the gate control circuit 7,
Controls the gate of thyristor 8 based on the output from
The charge of the capacitor 4 is discharged through the thyristor 8 based on the output from the pulsar 6, and a spark is generated between the spark plugs 9 by the voltage of the secondary coil of the ignition coil 5 generated by the discharge current of the capacitor 4. A capacitive discharge ignition device (CDI) 10 to be generated is constructed.

The output voltage of the AC generator 1 rectified by the diode 11 is supplied to the battery 12 to charge the battery 12.

On the other hand, the output voltage of the AC generator 1 rectified by the diode 11 is supplied to the DC load such as the starter through the main switch 13 in the key switch.

Further, the output voltage of the AC generator 1 rectified by the diode 11 is the patrol switch 14,
It is grounded via a patrol light 15 as an external indicator light and a roof switch 16. Here, the patrol switch 14 is configured to be inserted into the circuit by inserting the plug of the patrol switch 14 into a socket 17 (see FIG. 2) provided in the vehicle, and the patrol switch 18 is connected to the patrol switch 14 and It works together.

The patrol light 15 is composed of a motor 151 and a lamp 152 having a selective shield which is rotatably driven by the motor 151, and substantially blinks when the motor 151 is driven. The roof switch 16 is controlled to be on when the patrol light 15 is installed at a predetermined position on the vehicle roof.

The drive coil 191 of the patrol relay 19 is connected in parallel to the patrol light 15 and the contact point 192 of the patrol switch 18 and the patrol relay 19 is connected.
And are connected in parallel. The output voltage of the AC generator 1 rectified by the diode 20 is selectively grounded through a parallel connection circuit of the patrol switch 18 and the contact 193 of the patrol relay 19 and a series circuit of the ignition switch 21, and is supplied to the CDI 10 as a power supply voltage. AC generator 1
Is configured to be selectively applied.

On the other hand, the output voltage of the AC generator 1 rectified by the diodes 2 and 3 and the reference voltage are level-compared in the rotation speed comparison circuit 22, and the rotation speed comparison circuit 22 is compared.
Controls the gate control circuit 7 by the output of the rotation speed comparison circuit 22 only when the roof switch 16 is in the ON state (output voltage of the AC generator 1 rectified by the diodes 2 and 3> reference voltage). The gate control voltage of the thyristor 8 output from the gate control circuit 7 is cut off to prohibit the thyristor 7 from conducting.

Here, the output voltage of the AC generator 1 rectified by the diodes 2 and 3 corresponds to the rotational speed of the crankshaft driven by the engine, and the reference voltage of the crankshaft is such that the vehicle cannot run. The voltage is set to correspond to the rotation speed.

In the present embodiment configured as described above,
In the state before inserting the key switch, or before rotating the main switch 13 to the ON state position even if it is inserted,
The ignition switch 21 is on. Further, when the plug of the patrol switch 14 is not inserted into the socket 17, the contacts 192 of the patrol switch 18 and the patrol relay 19 are in the ON state, and the output terminal (voltage) of the alternator 1 is grounded, The spark plug 9 does not perform the ignition operation when the power supply voltage is not applied to the CDI 10.

When the key switch is inserted and the main switch 13 is turned to the ON position, the main switch 1
3 is controlled to an on state, and the ignition switch 21 is controlled to an off state. Since the main switch 13 is turned on, the voltage of the battery 12 is applied to the DC load, the starter and the like can be driven, and the engine is started by driving the starter.

On the other hand, since the ignition switch 21 is turned off, the output terminal (voltage) of the alternator 1 is grounded regardless of the states of the contacts 192 of the patrol switch 18 and the patrol relay 19 to drive the engine. The output voltage of the alternator 1 generated by is applied to the CDI 10, and the CDI 10 starts operating.

In this state, the roof switch 16
Is off, the output of the gate control circuit 7 is not interrupted by the comparison output of the rotation speed comparison circuit 22, and the thyristor 8 is controlled by the output from the gate control circuit 7 regardless of the comparison output of the rotation speed. Continuity is controlled,
The vehicle runs normally based on the driver's instructions.

When the patrol light 15 is installed at a predetermined position on the vehicle roof in order to stop the vehicle and display that a load or the like is being delivered, the roof switch 16 is turned on. Further, when the plug of the patrol switch 14 is inserted into the socket 17, the patrol switch 14 is controlled to be in the ON state.

As a result, a voltage is applied to the patrol light 15, the patrol light 15 substantially repeats blinking, and the blinking of the patrol light 15 indicates that delivery is in progress. Now, set the key switch to the lock position and pull out the key switch.

Even if the key switch is pulled out, the voltage is applied to the patrol light 15, the patrol light 15 continues to blink, and it is indicated that the delivery is in progress.

In this state, the engine is in a driven state. In this case, however, the roof switch 16 is in the on state, and as a result of comparison in the rotation speed comparison circuit 22,
Only when (output voltage of the AC generator 1 rectified by the diodes 2 and 3> reference voltage), the rotation speed comparison circuit 2
The comparison output of 2 cuts off the gate control voltage from the gate control circuit 7 and inhibits the conduction of the thyristor 8.
Therefore, even if the output voltage of the AC generator 1 rectified by the diodes 2 and 3 exceeds the reference voltage,
Since the crankshaft is not rotationally driven by the engine, the vehicle does not run and remains stopped.

However, since the AC generator 1 is driven until the output voltage of the AC generator 1 rectified by the diodes 2 and 3 reaches the reference voltage, the output voltage of the AC generator 1 rectified by the diode 11 is driven. The patrol light 15 is driven by, and the battery 12 is not consumed. Moreover, since the key switch is removed, vehicle theft during delivery can be prevented.

When the plug of the patrol switch 14 is unplugged from the socket 17 or the patrol light 15 is removed from a predetermined position on the vehicle roof, the voltage application to the patrol light 15 is cut off and the patrol light 15 is turned off. When the patrol light 15 is removed from a predetermined position on the vehicle roof, the roof switch 16 is returned to the off state,
Gate control circuit 7 based on the comparison output of the rotation speed comparison circuit 22
The control is released and the vehicle can be driven and run normally.

Further, when the patrol light 15 is installed at a predetermined position on the vehicle roof, the roof switch 16
Is on, the control of the gate control circuit 7 by the comparison output of the rotation speed comparison circuit 22 is not released, and the vehicle cannot run. As a result, Patrol Light 1
It is not possible to drive while 5 is lit or blinking.

In the above embodiment, the roof switch 16 may be omitted and the patrol switch 14 may be connected to the position of the roof switch 16 shown in FIG.

As described above, according to the vehicle external indicator lamp lighting system of the present invention, the external indicator lamp is turned on during the period in which the lighting instruction means is lit and displayed, and the external indicator lamp is the output of the AC generator. Since it is turned on by the voltage, there is an effect that the battery is not consumed.

Further, during the lighting instruction period, the ignition device controls the rotation speed of the crankshaft to a predetermined rotation speed at which the vehicle does not run under the control of the control means. Therefore, during the lighting instruction period, the output voltage of the AC generator is predetermined. There is also an effect that the voltage is maintained and no trouble occurs in lighting the external indicator lamp.

Further, during the lighting instruction period, the rotation speed of the crankshaft is controlled to a predetermined rotation speed at which the vehicle does not run, so the vehicle does not run. Moreover, since the ignition switch circuit is shut off by the shut-off means during the lighting instruction period, there is no problem even if the ignition switch is pulled out, and there is an effect that there is no risk of the vehicle being stolen.
