Description

Brake light lighting control device of car

The present invention relates to a brake light lighting control device for a vehicle. More specifically, the brake light is turned on when the effort applied to the brake pedal is gently applied, and the brake light is applied like an emergency light during sudden braking. The present invention relates to a brake light lighting control device that allows the driver of a rear vehicle to easily blink to prevent the collision from happening.

In general, the vehicle is equipped with various instruments and warning lights that indicate the driving status of the vehicle on the instrument panel in front of the driver's seat. It is to be recognized.

In addition, as a signal for informing other vehicles about the status of their vehicle between vehicles traveling on the road, turn signal lamps are installed at the front, rear, left, and right corners of the body, and the driver turns the left signal lamp or the right turn signal lamp as the driver operates the turn signal lamp switch. The turn signal lamp is flickering, and when the driver operates the emergency light switch installed separately from the turn signal lamp switch, the left and right turn signal lamps blink at regular intervals at the same time to drive the vehicle back and forth. It is supposed to inform.

Such turn signal operation switches are commonly referred to as combination switches, and are operated when the driver wants to change lanes or to change directions. Therefore, when the driver wants to change lanes during normal driving, the turn signal lamp is operated by operating the combination switch, and the lane is changed. Then, the vehicle driving in the scheduled lane will see the flashing state of the turn signal lamp in front of the vehicle. By reducing or reducing defensive driving, it prevents crash accidents.

In addition, the turn signal lamps installed on the front, rear, left and right sides of the vehicle are operated to blink at a predetermined period, but are used as emergency lights by operating them at the same time.

In addition, the brake signal is provided to display the speed change of the vehicle, in particular the deceleration, as well as the operation of the turn signal lamp for changing the direction. This is to be turned on when operating the brake device while driving to prevent the risk of collision accident for the driver traveling behind.

An example of this is shown in FIG. 1, when the driver presses the brake pedal 10, the metal terminal 11 is pushed in contact with the contact 13, and the brake switch 12 is turned on. Since the power of the battery 14 is applied to the brake lights 16 and 18 and the brake lights 16 and 18 are turned on, the driver who runs behind the vehicle knows that the vehicle in front of the vehicle is decelerating by viewing the lit brake light.

In addition, recently, many vehicles have installed auxiliary brake lamps, which are installed on the upper rear seats of the vehicle, which are closer to the driver's eye level driving behind them, so that they can be quickly recognized. Although not shown in the drawing, such auxiliary brake lights are installed in parallel with the brake lights 16 and 18 to perform the same operation as the brake lights 16 and 18.

However, in the conventional lighting system of the brake lamp, since the stepping force is applied to the brake pedal 10 and the metal terminal 11 and the contact point 13 of the brake switch 12 are kept in a steady light state, the vehicle of the preceding vehicle The driver of an inexperienced rearing vehicle who is not in a state of sudden accident or sudden danger while driving, but simply presses the brake pedal 10 lightly and turns on the brake lights 16 and 18 to reduce the vehicle speed. A sudden braking is misunderstood as a case of sudden braking. In other words, since the conventional brake light lighting system is not configured to allow the rear driver to distinguish braking completions, a sudden driving of the rear driving vehicle and the vehicle following it often cause a crash. .

Accordingly, the present invention has been made in order to solve the above-described conventional problems, the brake light is turned on when the pedal force applied to the brake pedal is made gentle to inform the driver of the rear vehicle of braking completion. An object of the present invention is to provide a brake light lighting control device for a vehicle that allows the brake light to blink like a flashing emergency light to give the rear vehicle a circumference.

The present invention for realizing the above object is provided with a front end terminal and a rear end terminal having a predetermined interval at the inlet and out of the brake switch, the first stage contact and the first end contact with the front end terminal by the movement of the entrance when the pedal pedal is supplied The two-stage contact, which is in rear contact with the rear terminal, is mounted in the brake switch, while the two-stage contact is connected to the input of the control unit for controlling the lighting of the brake lamp, and the base side of the transistor is connected to the output of the control unit. , First stage contact is branched to input part of control unit, collector side of transistor and brake light, and control unit turns off transistor by turning off transistor when time (T) between line contact and back contact is more than reference time (T1). In case of sudden braking with the time T between the line contact and the rear contact being less than or equal to the reference time T1, the turn on / off of the transistor is repeated so that the brake lamp flashes. It will have to.

Therefore, the present invention divides the power supply to the brake pedal into a gentle braking and a rapid braking according to the time, so that the control unit turns off the transistor when the braking is performed for a long time between the line contact and the rear contact in the brake switch. When the brake light is continuously applied to the lamp and the brake light is continuously turned on, and during rapid braking with a short time between the line contact and the rear contact, the transistor is turned on and off repeatedly so that the brake light blinks so that the following driver brakes. It is possible to recognize that the continuous lighting of the lamp is a gentle braking, and that it is easy to know that the brake is suddenly braked by the blinking brake light, such as an emergency light, so that a quick response can be taken.

Referring to the configuration and operation of the present invention in detail based on the accompanying drawings as follows.

According to the present invention, in a brake light lighting control apparatus of a vehicle in which power of the battery 14 is supplied to the brake lights 16 and 18, a tip terminal having a predetermined interval in the entrance part 20 of the brake switch 12 ( 22) and the rear end terminal 24 are formed, and the first stage contact point 26 and the rear end terminal are brought into pre-contact with the front end terminal 22 by the movement of the entry and exit part 20 when the pedal pedal 10 is supplied with a stepping force. A two-stage contact 28, which is in rear contact with the 24, is mounted in the brake switch 12, while the two-stage contact 28 is provided with a control unit 30 for controlling the lighting of the brake lights 16,18. In addition to being connected to the input unit, the output side of the control unit 30 is connected to the base side of the transistor 32, the first stage contact 26 is the input side of the control unit 30 and the collector side of the transistor 32 and the brake The control unit 30 turns on the transistor 32 when the time T between the line contact and the rear contact is greater than the reference time T1, branched to the lamps 16 and 18, respectively. The brake lamps 16 and 18 to be turned on, and when the rapid braking time T between the line contact and the rear contact is equal to or less than the reference time T1, the transistor 32 repeats the turning on / off periodically.

In the transistor 32, the current adjusting resistor 34 is connected to the emitter side.

2 is a view showing a brake lamp lighting control device according to the present invention.

Herein, the present invention divides the lighting control of the brake lights (16, 18) into gentle braking and sudden braking according to the speed of the pedal force applied to the brake pedal (10) to easily inform the driver of the braking situation to the driver of the rear vehicle. to be.

The configuration for the present invention forms the front end terminal 22 and the rear end terminal 24 with a predetermined interval to move the inside of the brake switch 12 to the brake pedal 10 to supply the pedal force, Equipped with a first stage contact 26 for first contact with the front end terminal 22 of the moving part 20 moving in the brake switch 12 and a second stage contact 28 for rear contact with the rear end terminal 24. will be.

In addition, the two-stage contact 28 is connected to the input of the control unit 30 for controlling the lighting of the brake lights 16 and 18, and the base side of the transistor 32 is connected to the output of the control unit 30, The first stage contact 26 is connected to the input of the control unit 30, the collector side of the transistor 32, and the brake lamps 16 and 18, respectively.

When the time T between the line contact and the rear contact is equal to or greater than the reference time T1, the control unit 30 turns off the transistor 32 so that the brake lights 16 and 18 are turned on. When sudden braking with the time T between the rear contacts being less than or equal to the reference time T1, the control unit 30 outputs a bias voltage, which is a periodic square wave, so that the transistor 32 repeats the turning on / off. ) Is blinking.

Therefore, when the driver presses the brake pedal 10 due to various situations, the stepped force applied to the brake pedal 10 is moderate, and thus the front end terminal 22 of the entry and exit portion 20 in the brake switch 12 is moderate. And the time T between the line contact with which the first stage contact 26 comes into contact and after the rear contact with which the rear end terminal 24 and the second stage contact 28 come into contact with each other is equal to or greater than a preset reference time T1. When the control unit 30 determines, the transistor 32 having the switching function connected to the base side of the control unit 30 does not output the bias voltage so that the control unit 30 is turned off. Accordingly, the brake lights 16 and 18 are turned on by applying a current more than the light that can be supplied from the battery 14 by the line contact between the front end terminal 22 of the brake switch 12 and the first end contact 26.

On the contrary, when the control unit 30 determines that the brake unit is suddenly braked because the time T is less than the preset reference time T1, the control unit 30 cycles the transistor 32 to turn on / off as an output unit. It outputs a bias voltage which is a typical square wave. Accordingly, when the current supplied from the battery 14 in line contact is turned on of the transistor 32, part of the current flows to the emitter side current adjusting resistor 34 of the transistor 32 and the ground, so that the brake lights 16 and 18 Only currents that can be turned on or less will flow, causing the brake lights 16, 18 to turn off or turn on weakly. When the transistor 32 is turned off by the bias voltage, which is a periodic square wave, the brake lights 16 and 18 are turned on by applying a current more than the light that can be supplied from the battery 14 like a gentle braking state.

Accordingly, during sudden braking, the brake lamps 16 and 18 blink and blink in the repetition of the turn-on and turn-off of the transistor 32.

Therefore, the present invention is to light the brake lights (16, 18) as in the case of moderate braking, and to flash like emergency lights when braking, so that the braking state can be more accurately informed to the driver of the vehicle driving behind. will be.

As described above, the present invention divides the stepping force supply to the brake pedal 10 into a gentle braking and a sudden braking according to time, and provides a control unit during gentle braking in which the time between the line contact and the rear contact in the brake switch 12 is long. 30 turns off the transistor 32 so that the battery 14 power is continuously applied to continuously turn on the brake lights 16 and 18, and in case of rapid braking with a short time between the line contact and the rear contact. By repeatedly turning the transistors on and off, the brakes and the like blink, the present invention has an effect that the driver of the following vehicle can easily know the braking state of the vehicle, thereby preventing collision accidents.
