【Example】

 An embodiment of a control device for an auxiliary stop signal light for a vehicle or the like according to the present invention will be described with reference to FIGS. As shown in the schematic connection diagram of FIG. 1, the present invention focuses on the auxiliary stop signal light L3 in the conventional device of FIG. 8 and takes advantage of its mounting position to make the stop signal signal more accurate and farther. The control device U is added to the schematic connection diagram of the various warning signal lights in FIG. 8 so that they can be visually recognized. The auxiliary stop signal light L3 is of a light bulb type or a light emitting diode (LED) type that does not cause disconnection, and its mounting position is at a high position at the rear of the vehicle close to the driver's line of sight (for example, the upper portion of the rear window). ), Only one is permitted, and the color (red) and illuminance are also specified by law. The hazard lamps are also stipulated by law to have a yellow or orange color and a blinking frequency of 100 to 120 times per minute.

FIG. 2 shows a block diagram of a specific configuration example of the control unit U shown in FIG. In FIG. 2, 1 is a timer circuit, 2 is a switching circuit, 3 is a relay driving circuit, 4 is a relay, 5 is a NAND circuit, a is a power supply terminal, b and c are sensor terminals, and d is an auxiliary stop signal light connection terminal. Is. In FIG. 2, when the positive voltage of the storage battery B is applied to the terminal a by depressing the foot brake pedal P, the switching circuit 2 becomes conductive, the output thereof causes the relay driving circuit 3 to become conductive, and the relay 4 operates to activate the relay contact. When x and y are connected, the auxiliary stop signal light L3 connected to the terminal d is instantly turned on. Then, after a lapse of a fixed delay time determined by the time constant provided in the timer circuit 1 from the time when the power is supplied, the negative single-shot pulse output from the timer circuit 1 is applied to the switching circuit 2 to cause the switching circuit 2 to operate. Reversed, the output turns off the relay 4, the relay contacts x and y are opened, the auxiliary stop signal light L3 connected to the terminal d is turned off, and after a certain time, the relay 4 is automatically restored again, Continue to turn on the auxiliary stop signal light L3.

The terminals b and c are connected to the hazard lamps L4 and L5, and when it is detected that the hazard lamps L4 and L5 are simultaneously lit, the output of the NAND circuit 5 becomes low, and this low output causes the timer circuit 1 to output. When the discharge of the time constant circuit is forced and both hazard lamps L4 and L5 are extinguished, the output of the NAND circuit 5 rises to almost the power supply voltage and becomes high. This high output causes the time constant circuit of the timer circuit 1 to The discharge of the current is stopped, the time constant circuit becomes the normal charging operation, and after a certain delay time, the negative single pulse is applied from the timer circuit 1 to the switching circuit 2, the relay 4 is turned off, and the auxiliary stop signal light L3. Turns off. That is, the auxiliary stop signal light L3 blinks in synchronization with the hazard lamps L4 and L5.

FIG. 3 shows an example of an internal equivalent circuit of a general-purpose Schmidt circuit integrated device IC1 having a timer function, which is used in the timer circuit 1 in FIG. 2, and the control circuit of the present invention constructed by using this device IC1. FIG. 4 shows a circuit diagram of a concrete example of the above, and a more detailed description will be given together with the timing chart of the circuit operation of FIG. 4 shown in FIG.

In FIG. 4, first, when the foot brake pedal P is stepped on, the positive voltage VCC (usually 12 V or 24 V) of the storage battery B is applied to the terminal a as a power source. The transistor Q5 turns on because a bias voltage is generated by the resistor R2, and a voltage drop occurs at the resistor R3. This voltage drop becomes the bias voltage of the transistor Q6, the relay RL turns on, and the relay contacts x and y are connected. Then, the power supply voltage (plus) is output to the terminal d. That is, the auxiliary stop signal light L3 connected to the terminal d is instantly turned on.

On the other hand, at the charging terminal e of the timer circuit element IC1, charging of the capacitor C1 is started by the resistor R1 as shown in FIG. 5A, and after a certain delay, the voltage at the point e reaches the threshold voltage P. Then, point f sharply drops to zero potential. Then, the charging current flows through the resistor R2 to the capacitor C2 connected to the point f, the voltage at the point g decreases as at t1 in Fig. 5 (C), the relay drive circuit turns off, and the relay contacts x, y Becomes an open state, the terminal d becomes zero potential, and the auxiliary stop signal light L3 goes out.

However, as the capacitor C2 approaches full charge, the voltage drop due to the charging current flowing through the resistor R2 decreases, and a regular bias voltage is gradually applied. At point S in FIG. It is turned on, the power supply voltage is output to the terminal d, and the auxiliary stop signal light L3 is turned on. FIG. 5D shows the voltage applied to the auxiliary stop signal light L3.

Here, looking at the sensor terminals b and c and the NAND circuit 5 connected to the hazard lamps L4 and L5, when the hazard lamp L4 or L5 is turned on and off by the route change signal switch S3, FIG. As shown in (E) and (F), since the output i of the NAND circuit 5 remains fixed to the power supply voltage, the reverse voltage is applied to the diode D1 in FIG. 3, and the diode D1 is in the "open" state in the switch. Therefore, the terminal e and the terminal i remain separated.

Next, considering the case where the hazard lamps L4 and L5 perform the point reduction lighting operation, as shown in FIG. 7, the points b and c have a high potential, that is, the hazard lamps L4 and L5 are simultaneously left and right. During the period from t11 to t12 that is lit up, the potential is almost zero, and during the period from t12 to t13 when both left and right are off, the potential is kept almost equal to the power supply voltage. Since it becomes almost zero, the diode D1 inside the IC1 becomes conductive and the electric charge stored in the capacitor C1 is discharged. That is, the point f rises to almost the power supply voltage, and the capacitor C2 is discharged by the resistors R2 and R4. Since the transistors Q5 and Q6 are kept on, the auxiliary stop signal light L3 is still lit, but when the hazard lamps L4 and L5 are both extinguished between t12 and t13, point i Becomes a high potential and the diode D1 is disconnected, so the time constant circuit of the resistor R1 and the capacitor C2 starts normal charging and starts charging, and when the threshold level P is reached, the f point drops to zero. However, the transistors Q5 and Q6 are turned off, the contacts x and y of the relay RL are opened, and the auxiliary stop signal light L3 is turned off.

The above operation is repeated while the hazard lamps L4 and L5 are blinking and lighting. That is, the hazard lamps L4 and L5 and the auxiliary stop signal light L3 blink in synchronization with each other. Naturally, when the foot brake pedal P is released, the power supply to the terminal a is stopped, so that all the operations of the device of the present invention are stopped and useless power consumption is prevented.

[Effect of device]

According to the control device for an auxiliary stop signal light for a vehicle or the like according to the present invention, the auxiliary stop signal light is electronically blinked and turned on a plurality of times by one brake pedal operation, and further synchronized with the danger avoidance warning light. By turning on and off the auxiliary stop signal light as well, the visibility in the rear is improved and the caution signal can be transmitted reliably to a farther distance, which has a great effect of preventing accidents.

Even for a beginner, the stop signal light is controlled in the same manner as the pumping brake operation, so that an accident such as a rear-end collision can be prevented.

Even in an unexpected situation, a signal similar to the pumping brake operation is automatically issued, so that an accident such as a rear-end collision can be prevented in advance.

Since it is composed of general general-purpose electronic components, it can be provided at a small size and low price.

It can be applied to both a light bulb type and an LED type auxiliary stop signal light and is highly versatile.
