The present invention relates to a flashing control device for a brake lamp mounted on the rear of a vehicle so that the driver can easily check the deceleration or stop situation when the brake is operated while driving. According to the driving speed at the time of brake operation, it is possible to have the flashing or the continuous lighting of the corresponding brake lamp so that the driver or the pedestrian in the rear can easily detect the deceleration of the driving vehicle and take the precautionary attitude. The present invention relates to an automobile brake lamp blink control device developed for the purpose of minimizing accident occurrence.

Conventionally, the type of brake lamp equalizer applied to the rear of a vehicle is a type in which the brake lamp is turned on when the brake pedal is pressed for braking, and the deceleration is progressed while stepping rapidly or continuously during the high speed driving. In daytime operation, it is difficult to check the lighting status of the brake lamp when the surrounding weather is not good. Also, in the case of the night, the tail light is turned on, so it is confused in judging the braking situation by overlapping with the lighting of the brake lamp. In recent years, the use of an auxiliary brake lamp in a separate position from the tail light has been used to resolve confusion with the tail light.However, the braking distance is relatively longer in the high-speed driving situation at night on highways and automobile roads. Because of poor vision, the forward driver The repeated operation over a brake pedal with means for recognizing the same conditions several times, or left, by operating the right flashing light is bad to be sent to the braking signal causing the driver to the rear.

This is not only possible for the experienced driver, but also in a sudden deceleration situation, it is difficult to operate the signal as described above without considerable attention, and thus has frequently caused a crash accident.

Therefore, in recent years, the brake pedal for braking, as introduced in Utility Model Registration No. 87-13128, "Flashing Brake Light Equalizer for Automobiles," is proposed as a way to solve the above problems in the braking situation of brake lamps. In Brake lamp, the brake lamp flickers at regular intervals.

In this case, the brake lamp blinks continuously even when the vehicle is stopped to wait for a signal while driving in the city, resulting in defects such as visual disturbance and anxiety of the driver around the street due to the distracting atmosphere. It is difficult to spread.

In other words, there is no problem in driving a motorway or a highway, but there is a drawback in that the driving of the brake lamp cannot be used continuously regardless of the surrounding situation.

Accordingly, the present invention has been developed to solve the above problems and the contents thereof will be described in detail as follows.

As a key aspect of the present invention, in response to the driving speed at the time of operating the brake of a vehicle, the brake ram lights have a flashing cycle at high speeds of more than a set speed (eg, 60 km / Hr). It is to bring continuous brake lamp lighting operation.

On the other hand, the brake lamp lighting relationship or the conventional brake lamp lighting relationship as described above is a key element of the present invention so that the driver can be selected to switch according to the driving situation as described in detail according to Figure 1 As shown in the figure, the brake operation detection / operation time control unit 1 is configured to detect the vehicle brake operation and to extend the flashing operation of the brake lamp for a predetermined time even after the brake operation when the periodic flash operation is selected. Brake lamp continuous light and blink selector (2), which can be selectively adjusted to perform periodic flashing operation or continuous lighting of lamps LBK1 and LBK2, and a driving speed detecting unit (3) for detecting the current vehicle driving speed; The driving speed detecting unit 3 detects the current vehicle driving speed and the output signal of each unit is adjusted. A brake lamp flicker control system comprising a drive signal comparison selection / lighting and a flicker control unit (A) which controls the lighting / flashing operation of the brake lamp according to the detected driving speed and simultaneously transmits a signal corresponding to the result of the comparison. It is designed to have the main flashing operation or continuous lighting of the brake lamp by the selection at the time of brake operation and to have the flashing cycle of the corresponding brake lamp according to the traveling speed at the time of brake operation.

Here, the adoption of the brake lamp continuous light and the flashing selection part 2 need not be adopted or adopted as necessary.

This will be described in more detail through an embodiment of the present invention.

Example 1

As shown in FIG. 2, an interlocking switch (SBK1, SBK2) and condensers (C1, C2) are configured to detect a brake operation state and a brake operation detecting / operating time control unit (1) and an interlocking two-stage switch ( Brake lamp continuous light consisting of SSL1, SSL2) and resistor R1, flashing selector 2, and the rotational speed of the wheel of the car, that is, the current traveling speed, is an optical coupling element or a magnetic element having a HALL effect. A signal from the brake operation detection / operation time control unit 1 through the traveling speed detecting unit 3, the brake lamp continuous light, and a flashing selecting unit 2 which are sensed by a sensing means such as The microcomputer 4 and the resistors R2 and R3, the capacitor C3, the diode D1, the transistor Q1, and the relay RY1 that combine the signals from the speed sensing unit 3 and send out corresponding signals. According to the current driving speed from the microcomputer BPK is a brake pedal and SRY consisting of a drive signal comparison selection / lighting and a flashing control unit (A) including a flashing control unit (5) which controls the lighting and flashing operation of the brake lamps (LBK1, LBK2) in response to a periodic flashing signal. Is a relay contact.

According to one embodiment of the present invention configured as described above, when the driver presses the brake pedal BBPK (Fig. 4 at an arbitrary time point t1), the interlocking switches SBK1 and SBK2 of the brake lamp operation detection / operation time control unit 1 are applied. ) Turns on at the same time. If the movable contact of the interlocking two-stage switch (SSL1, SSL2) in the brake lamp continuous light and the flashing selector (2) is switched to one fixed contact (a), the power supply voltage (Vcc) ) Is charged to the capacitors C1 and C2 through the one-side interlock switch (SBK1), the interlocking two-stage switch (SS L1) and the resistor (R1), and at the same time the microcomputer (in the drive signal comparison selection / lighting / flashing control unit (A) It is applied to the input terminal In1 of 4) (Fig. 4 (A)).

The drive signal comparison selection / lighting, which has received such a brake operation signal (Fig. 4 (a)) to one input terminal In1, is applied to the other input terminal In2 by the microcomputer 4 in the flashing control unit A. The driving speed detection unit 3 transmits a signal (Fig. 4 (b)) according to the current traveling speed to the output terminal OUT1. Accordingly, the transistor Q1 of the flashing control unit 5 in the drive signal comparison selection / lighting and flashing control unit A repeats the "turn on-turn off" at the signal cycle as shown in FIG. The contact SRY of the relay RY1 repeats the "off-on" state, so that the other interlock switch (SBK2) in the brake operation detecting section (1) and the other side in the flash selector (2), the brake lamp sustaining lights, etc. It is possible to control the flashing operation of the brake lamp by supplying the power supply voltage Vcc applied to the brake lamps LBK1 and LBK2 via the signal switch as shown in FIG. The cycle has a very fast flashing cycle when the driving speed at the time of brake operation is high, and has a slow flashing cycle as the speed decreases, and then a predetermined time t2 as shown in FIG. Very low speed or continuous at low speed It is so like can be made.

Example 2

The specific circuit diagram shown in FIG. 3 is another embodiment according to the present invention, which is composed of interlock switches (SBK1, SBK2) and capacitors (C1, C2) to detect the brake operation and at the same time the periodic flashing operation. When the brake is selected, the brake operation detection / operation time control unit 1, the brake lamp continuous light, the flashing selection unit 2, and the current driving speed of the vehicle are designed to extend the flashing operation of the brake lamp for a predetermined time even after the brake operation. A voltage signal converter converting the output signal of the traveling speed detection unit, the waveform shaping unit 6, which is a means for shaping the output signal of the traveling speed detection unit into a square wave, and outputting the output signal of the waveform shaping unit; 7) and the lighting blink selector 8 consisting of a comparator OP1, a variable resistor VR1, a transistor Q1, a capacitor C3, C4, a resistor R2, a relay RY1, a diode D1, and The brake lamp continuous light, dot When the brake operation detection / operation signal control unit 1 through the selection unit 2 and the output signal of the waveform shaping unit 6 are supplied to both input terminals, an end cake AND sends a signal corresponding thereto. Therefore, the driving signal comparison selection / lighting and flashing control unit (A) controls and selects the lighting / flashing operation of the brake lamp according to the detection speed of the traveling speed detecting unit.

According to another embodiment of the present invention configured as described above, when the driver steps on the brake pedal BPK in a deceleration or stop situation, that is, at an arbitrary time point t1 of FIG. (1) The interlock switch (SBK1, SBK2) is turned on at the same time. At this time, the movable contact of the interlocking two-stage switch (SSL1, SSL2) in the brake lamp continuous light and the flashing selector (2) is fixed to one side. (a) If the state is selected and switched by the driver, the power supply voltage (Vcc) is charged to the capacitor (C1) at the same time through the interlock switch (SBK1), the two-stage switch (SSL1), and the resistor (R1). Signal comparison output / lighting, flashing A high level signal is supplied to one input terminal of the AND gate AND in the control unit A, and an end receiving the brake operation signal (Fig. 4 (a) in the drawing) as described above. The driving speed detecting unit 3 is connected to the other input terminal of the gate AND. When the speed detection signal according to the current speed of the signal is applied while being shaped as a square wave () through the waveform shaping unit 6 in the driving signal comparison output / lighting and blinking control unit A, the AND gate AND Blinking signal is output. (And gate output is output of driving speed detection part through waveform shaping part only when brake is operated.)

That is, the AND gate AND outputs a high level signal when the signals applied to the two input terminals are the same high level signal, and the signals applied to the two input terminals are different from each other, or the two input signals are the same. In the case of a low level signal, a low level signal is output.

In addition, the speed detection signal according to the current speed from the traveling speed detecting unit 3 is applied to one input terminal of the AND gate AND through the waveform shaping unit 6, and the driving signal comparison output / lighting / flashing control unit A When the voltage signal converter 7 is applied to the internal voltage signal converter 7, the comparator is converted into a voltage signal (Fig. 4 (b)) through the voltage signal converter 7 and the power supply voltage Vcc is applied to the inverting terminal (-). It is applied to the non-inverting terminal (+) of OP1). (In this case, the power supply voltage is set so that the comparator operates only at an appropriate driving speed (more than 4 degrees (t2) through experiments in advance) and can be adjusted by the variable resistor VR1.)

The comparator OP1 receiving such a signal compares the two signals, and when the output voltage of the voltage signal converter 7 is smaller than the power supply voltage applied to the inverting terminal (-), the corresponding low level signal is larger. Next, the high level signal is sent through the resistor R2 to the transistor Q1 in the on / off selection section 8 to turn on and turn off the transistor Q1.

That is, when the output signal of the voltage signal converter 7 is below t2 (when the vehicle driving speed is below a certain speed), the comparator OP1 outputs a low level signal, so that the transistor Q1 is turned off to the relay RY1. Since the power supply voltage is not applied, the contact voltage ccc of the relay RY1 is applied through the one-side interlock switch SBK2 and the interlocking two-stage switch SSL2 in the brake operation detection / operation time control unit 1 (Vcc). Since the contact point (b) of is connected, the power supply voltage is applied to the brake lamps LBK1 and LBK2 so as to be in a continuous lighting state. (In other words, if the driving speed is below a certain speed, it maintains the continuous lighting state.)

In addition, the driving speed of the vehicle increases and the output of the voltage signal converter 7 at the time of the brake pedal operation BPK is larger than the power supply voltage Vcc applied to the inverting terminal (-) of the comparator OP1. When outputting the high level signal (the driving speed is greater than t2 in FIG. 4 (b)), the transistor Q1 is turned on and the power supply voltage Vcc is applied to the relay RY1, so that the relay RY1 operates. The contact (c) is driven through the output contact (a) of the AND gate (brake lamp sustaining light, flashing selector 2, output signal of the brake operation / operation time control unit 1 and waveform shaping unit 6). The blinking operation of the brake lamps LBK1.LBK2 is connected to a signal in which the output signal of the speed detecting unit 3 is combined (the contact with the output of FIG. 4C), as shown in FIG. It can be controlled by the period of the signal, and the blinking period is when the running speed at the time of brake operation is high. It has a very fast flashing cycle and gradually slows down as the speed decreases, and the output signal of the voltage signal converter 7 as described above at a predetermined time t2 as shown in FIG. Less than the power supply voltage), that is, at a very low speed or a stopped state below a predetermined speed, continuous lighting can be achieved.

Here, the output signal of the voltage signal converter 7 increases and decreases in proportion to the output signal of the travel speed detecting unit 3.

That is, when the driving speed is high, the output signal of the voltage signal converter is large and the output signal gradually decreases as the driving speed decreases.

On the other hand, in Examples 1 and 2, since the charges are charged in the capacitors C1 and C2 in the brake operation detection / operation time control unit 2, when the brake continues to operate after the operation of the brake, the brakes are operated for a predetermined time as much as the amount of charge charges. It is possible to extend the flashing operation of the lamp.

On the other hand, if the brake lamps LBK1 and LBK2 do not need periodic flashing operation, move the brake contacts to the other fixed contact point (b). When switching the brake pedal (BPK) each time the power supply voltage is supplied to the brake lamp (LBKK1, LBK2) through the one-side interlock switch (SBK1), interlocking two-stage switch (SSL1), relay contact (SRY) This will allow continuous lighting, not operation.

As can be seen from the above, the present invention makes it possible to perform periodic flashing operation or continuous lighting of the brake lamps LBK1 and LBK2 according to the selection at the time of brake operation, as well as corresponding to the driving speed at the time of brake operation. By having the blinking cycle of the brake lamp, the following car driver can immediately detect it and take countermeasures, which can be a great help for the safe driving of the car.
