The signal comparison section 23, the resistors R ₄₁ and R ₄₂ and the photocoupler PC for transmitting the insulating signals while the output signals of the code comparison section 23 are insulated, and a power supply ( B ⁺⁾ are applied to the After a reset in initial capacitor to turn on automatic and manual alternately by counting the transmitted signal of the signal transmission unit (24) (C _36), diode (D ₂₇ ~D _29), resistor (R _43), an inverter ( IV ₃₁ , IV ₃₂ ) and an automatic / manual control unit 25 including a sequential counter 251, a resistor R ₄₄ for driving automatic and manual according to the output signal of the automatic / manual control unit 25, and a diode ( D ₃₀ ), a condenser (C ₃₇ ), a relay (RY ₃₁ ), and a relay switch (RYS ₃₁ ).

As shown in FIG. 4, the automatic flashing control unit 30 includes a square wave composed of a capacitor C ₅₁ and C ₅₂ , a resistor R ₅₁ and R ₅₂ , and a flip-flop 310 to convert the vehicle speed signal into a square wave signal. The frequency converter is configured to convert the pulse signal output from the square wave converter 31 and the resistors R ₅₃ to R ₅₅ , the transistors TR ₅₁ , and the capacitors C ₅₃ and C ₅₄ to a voltage. A resistor R ₅₆ and R ₅₇ and a comparator 330 for generating a headlight lighting control signal by comparing the voltage converter 32 and the output signal of the frequency / voltage converter 32 with a preset reference voltage. In accordance with the headlight lighting control unit 33 and the headlight lighting control signal outputted by the headlight lighting control unit 33, the operational amplifier 340, the capacitors C _{55 to} C ₅₇ , and the resistor (for driving automatic lights such as headlights); R ₅₈ ~R _60), a transistor (TR _52), a diode (D _51), the relay (RY ₅₁₎ and a headlamp automatically lighting-driving the relay switch (RYS ₅₁₎ It consisted of 34.

In the above, the headlight lighting signal is input at high potential when the driver turns on the headlight switch (not shown), and the key switches K _{11 to} K _{1 N} and the key switches K _{31 to} K _{3 N} are the same. Set it.

According to the present invention configured as described above, the decoder integrated device 110 of the decoder 11 of the remote control transmitter 10 decodes the signals of the keyswitches K _{11 to} K _1N while the power source B ⁺ is applied. The decoded code is serially output and input to the transmitter 12.

When the user presses the drive switch SW in such a state, the power source B ⁺ is applied to the transmitter 12 through the drive switch SW, so that the transmitter 12 operates normally and the decoder integrated. A predetermined code output from the device 110, that is, a code corresponding to the keyswitch K _{11 to} K _1N is applied to the antenna ANT ₁₁ and transmitted.

In this way, the predetermined code transmitted from the remote control transmitter 10 is input to the remote control receiver 21 through the antenna ANT ₂₁ of the automatic / manual setting unit 20 and received, and the received code is a waveform shaping unit. Since it is input to the non-inverting input terminal (+) of the comparator 221 through the resistor R33 of the 22, the comparator 221 divides the received code and the power supply B ⁺ into the resistors R ₃₅ and R ₃₆ . One reference voltage is compared to output a square wave signal according to the received code.

Thus, the square wave signal output from the comparator 221 in the waveform shaping unit 22 are input to the comparator 231 of the code comparison unit 23, the comparator 231 is set to a predetermined key switch (K ₃₁ ~K _3N) The code of and the code of the square wave signal output from the comparator 221 is compared, and the high potential is output when the comparison result is the same.

The high potential output from the comparator 231 of the code comparator 23 is transmitted while being insulated from the light emitter of the photocoupler PC of the signal transmitter 24 to the light receiver, and the signal transmitted to the light receiver is an automatic / manual controller. A clock signal is input to the clock terminal CLK of the sequential counter 251 of (25).

On the other hand, auto / manual controller 25 power (B ⁺⁾ is generated generates a pulse signal via the initial power (B ⁺⁾ is a capacitor (C ₃₆₎ to be applied, and the pulse signal is an inverter (IV _31, IV ₃₂ After shaping through), since it is applied to the reset terminal RST of the sequential counter 251 through the diode D ₂₈ , the sequential counter 251 is reset and outputs a high potential to the output terminal Q ₀ . The clock signal applied to the clock terminal CLK is counted.

In such a state, when the clock signal is input to the clock terminal CLK by pressing the driving switch SW as described above, the sequential counter 251 counts it and outputs a high potential to the output terminal Q ₁ . TR ₃₁ is turned on, the relay RY ₃₁ is driven, and the movable terminal of the relay switch RYS ₃₁ is connected to one fixed terminal a ₃₁ so that the headlamp is automatically turned on according to the vehicle speed. Lights up automatically by control.

When the clock signal is input to the clock terminal CLK of the sequential counter 251 by pressing the driving switch SW again in such a state, the high potential is output to the output terminal Q ₂ of the sequential counter 251 and output. Since the high potential is applied to the reset terminal RST of the sequential counter 251 through the diode D ₂₉ , the sequential counter 251 is reset to output the high potential to the output terminal Q ₀ , and the output terminal At (Q ₁ ), low potential is output.

Therefore, contrary to the above, since the relay RY ₃₁ is not driven and the movable terminal of the relay switch RYS ₃₁ is connected to the other fixed terminal b ₃₁ , the driver turns on the headlight switch to input a high-pot light signal. When the high potential headlight lighting signal is applied through the relay switch RYS ₃₁ , the relay RY ₁ is applied and the relay RY ₁ is driven, and the relay switch RYS ₁ is connected and the headlight is turned on. The lighting of is controlled manually.

On the other hand, when the driving terminal of the relay switch (RYS ₃₁ ) is connected to one of the fixed terminal (a ₃₁ ) to drive the vehicle, the vehicle speed signal according to the driving of the vehicle, that is, the pulse signal is automatically flashing control unit ( The signal is applied to the set terminal ST of the flip-flop 31 via the condenser C ₅₁ of the square wave converter 31 of FIG. 30, and is output to the output terminal Q of the flip-flop 310. Since the charge is applied to the reset terminal RE of the flip-flop 310 while being charged in the capacitor C ₅₂ through the resistor R ₅₁ , the input vehicle speed signal is converted into a square wave signal by the flip-flop 310.

As such, the pulse signal output from the output terminal Q of the flip-flop 310 is applied to the base of the transistor TR ₅₁ through the resistor R ₀ of the frequency / voltage converter 32, and thus the transistor TR ₅₁ . It is repeatedly turned on and off, and as the transistor TR ₅₁ is turned on and off, the power source B ⁺ is charged to the capacitor C ₅₃ through the resistor R ₅₄ and discharged through the transistor TR ₅₁ . Repeatedly, the frequency / voltage converter 32 outputs a low potential and is applied to the inverting input terminal (-) of the comparator 330 of the headlight lighting controller 33.

Then, the comparator 330 continuously outputs a high potential, and the output high potential is amplified by the operational amplifier 340 of the headlight auto-lighting driver 34, and through the capacitor C ₅₆ and the resistor R ₆₀ . Since it is applied to the base of the transistor TR ₅₂ , the transistor TR ₅₂ is turned on, the relay RY ₅₁ is driven, and the relay switch RYS ₅₁ is connected.

Therefore, the headlight light signal inputted through the relay switch (RYS _51), and is through a relay switch (RYS ₁₁₎ applied to the relay (RY ₁₁₎ and the relay (RY ₁₁₎ is driven, the relay switch (RYS ₁₁₎ connected The headlights are turned on.

When the vehicle is not driven, there is no input vehicle speed signal, and thus the flip-flop 310 continuously outputs a low potential to the output terminal Q while the transistor TR ₅₁ is continuously turned off. ⁺ ) Is charged to capacitor C ₅₃ through resistor R ₅₄ and again to capacitor C ₅₄ through resistor R ₅₅ to apply a high potential to the inverting input terminal (-) of comparator 330. Will be authorized.

Then, in contrast to the above, the comparator 330 outputs a low potential, the transistor TR ₅₂ is turned off so that the relay RY ₁₁ is not driven, and the relay switch RYS ₁₁ is opened to turn off the headlight.

As described above, the present invention automatically turns on the headlights when the vehicle is running and turns off the headlights when the vehicle is stopped. You can drive safely.
