Now, a vehicle equalization control system and method according to an embodiment of the present invention will be described in detail with reference to the drawings.

1 is a block diagram schematically showing a configuration of a vehicle equalization control system according to an embodiment of the present invention.

1, a vehicle lighting control system 100 according to an exemplary embodiment of the present invention includes a navigation system 110, a speed measurement unit 120, a dimming sensor unit 130, a rear sensing unit 140, Unit 150 and a control unit 160. [0031]

The navigation 110 provides the route of the vehicle according to the current location and the destination of the vehicle using the road map and the GPS, and collects real-time traffic information through the Transport Protocol Expert Group (TPEG) service.

In particular, the navigation system 110 may recognize that the vehicle is in a congestion period or enter a congestion path on the basis of real-time traffic information, and may transmit it to the control unit 160.

Here, the congestion period may refer not only to congestion on roads without traffic lights, such as automobile roads and expressways, but also to a city road section where signal waiting is frequent.

The speed measuring unit 120 measures the current speed of the vehicle.

The dimming sensor unit 130 measures the amount of sunshine around the vehicle and identifies daytime and nighttime for automatic ON / OFF of the vehicle equalizer.

In particular, the dimming sensor unit 130 according to the embodiment of the present invention determines the presence or absence of a rear vehicle based on a change in resistance value according to detection of the brightness of the headlight of the rear vehicle.

For this purpose, the light control sensor unit 130 is provided in the vehicle in a plurality of ways in order to distinguish not only the rear vehicle (rear lane) but also the vehicles present on the rear left side (i.e., the left lane) and the right side .

The rear sensing unit 140 senses a rear vehicle existing within a predetermined distance from the rear of the vehicle using an ultrasonic sensor.

The equalizer 150 includes a headlamp 151 for securing a field of view in front of the vehicle at nighttime and a left side brake light 152 and a right side brake light 153 for indicating a brake operation state (on / off) . The reason why the brake lights 152 and 153 are divided into the left and right sides is that the left and right independent brightness can be adjusted according to the situation, and a description thereof will be described later.

The lamps Ramp of the headlight 151, the left brake light 152, and the right brake light 153 may be composed of a combination of at least one LED bulb.

Although not shown in the drawing, each of the lamps includes a brightness adjusting module that adjusts the brightness independently. The brightness adjusting module may include a snap motor or a variable resistor that adjusts the brightness of each lamp according to an applied control signal .

The processor ECU 160 collects various kinds of information obtained from the navigation 110, the speed measuring unit 120, the light control sensor unit 130 and the rear sensing unit 140 for controlling the equalization of the vehicle, Controls the brightness of the headlamp 151, the left brake light 152, and the right brake light 153 according to the processor.

2 is a conceptual diagram for explaining control conditions of a vehicle equalization control system according to an embodiment of the present invention.

Referring to FIG. 2, a controller 160 according to an exemplary embodiment of the present invention carries out Car Lights Control (hereinafter referred to as " Car Lights Control " CLC name) mode.

In this case, the control unit 160 uses the light control sensor unit 130 to grasp the surrounding light environment preferentially. If the day or the surrounding area is above a predetermined level, the CLC mode is not operated, The CLC mode can be activated only in the sunshine environment.

When the brake is operated in the CLC mode, the controller 160 increases the brightness of the braking lamps 152 and 153 or controls the brightness of the brakes 152 and 153 to a normal brightness (hereinafter, referred to as reference brightness).

The control unit 160 controls the rear sensing unit 140 to detect a vehicle existing within a predetermined distance from the rear of the vehicle if the vehicle speed is decelerated from high speed to low speed and the low speed state (e.g., 20 km / hour or less) Detection.

Also, the presence / absence of a vehicle behind the left / right lane is confirmed through the light control sensor unit 130. [

The control unit 160 decreases the brightness of the equalizer 150 as compared with the reference brightness when a vehicle behind the vehicle is detected in a congestion section where the vehicle is in a low speed state.

That is, when the distance from the rear vehicle is short in the congestion period, the brightness of the brake lights 152 and 153 is reduced compared to the reference brightness, and the headlamp 151 is also reduced in comparison with the reference brightness. At this time, the amount of decrease in brightness may vary depending on the intensity of the reference brightness, but it is preferably about 50 to 90% of the reference brightness.

3 and 4, a method of independently controlling the brightness of the brake lights 152 and 153 at the time of stopping the signal as well as during the stopping interval of the vehicle lighting control system 100 according to the embodiment of the present invention will be described do.

3 is a graph illustrating brightness control of a brake lamp before and after the CLC mode operation according to the first embodiment of the present invention.

3, when the vehicle equipped with the vehicle lighting control system 100 according to the first embodiment of the present invention is in a standby state for a two-lane signal, the strong brightness of the brake lights 152 and 153 It is possible to cause the driver's glare in both directions of the rear vehicle A and C in the two directions.

At this time, if both of the rearward vehicles A and C in both directions are present for a predetermined time or longer, the need for strong brightness of the brake light used for notifying the current braking and stopping state is reduced.

Therefore, when the CLC mode of the vehicle equalization control system 100 is in operation and the bidirectional rear vehicles A and C are present for a certain period of time or longer, the brightness of the left brake light 152 and the right brake light 153 is compared with the reference brightness It is possible to prevent the driver of the rear vehicles A and C from glare.

Next, FIG. 4 shows a state of independently controlling the brightness of the left and right braking lamps according to the second embodiment of the present invention.

4, when the vehicle on which the vehicle lighting control system 100 according to the second embodiment of the present invention is mounted is in the standby state for a two-lane signal, the rear vehicle A is driven only for a certain time The brightness of the left brake light 152 is reduced relative to the reference brightness to prevent the glare of the rear vehicle A and the brightness of the right brake light 153 is controlled to be the reference brightness, The braking state can be informed.

That is, when the vehicle exists for a certain time or more only in a rear lane, it is necessary to notify the vehicle coming from the other lane to the braking state. Therefore, by decreasing the brightness of only one brake lamp through independent control of the left and right brake lights 152 and 153, It is possible to secure safety with convenience and energy saving.

Although not shown in FIGS. 3 and 4, when the CLC mode is in operation in all embodiments, the brightness of the headlamp 151 of the vehicle being stopped may be reduced compared to the reference brightness, thereby preventing the front vehicle driver from glare.

A method of automatically adjusting brightness of a vehicle equalizing apparatus according to an embodiment of the present invention based on the above-described vehicle equalization control system will be described.

5 is a flowchart illustrating a vehicle equalization control method according to an embodiment of the present invention.

5, the vehicle lighting control system 100 checks the amount of light around the vehicle through the light control sensor unit 130 and determines whether the nighttime or the surrounding sunshine amount satisfies the condition that the equalizer 150 automatically operates (ON) (S101).

The vehicle equalization control system 100 collects real-time traffic information through the TPEG service of the navigation 110 and recognizes that the vehicle position is in a traffic volume congestion period or in a path congestion period (S102;

At this time, the vehicle equalization control system 100 starts the CLC mode for collecting the presence / absence of the rear vehicle, the vehicle speed, and the distance to the rear vehicle, and performs the same operation as the next step.

The vehicle lighting control system 100 determines that there is a rear vehicle if the output voltages of the plurality of light control sensor units 130 are equal to or greater than a predetermined reference value (e.g., 4V) (S103;

The vehicle equalization control system 100 collects the vehicle speed measured by the speed measuring unit 120 and recognizes that the vehicle speed is within a low speed range of 20 Km or less for a predetermined time (e.g., 3 seconds) after the brake operation (S104; Yes).

Also, the vehicle lighting control system 100 determines that the distance from the rear vehicle through the ultrasonic sensor of the rear sensing unit 140 is within a certain distance (e.g., 5 m) (S105).

The vehicle lighting control system 100 adjusts the brightness of the left and right brake lights 152 and 153 and the headlamp 151 according to the distance from the rear vehicle and the voltage of the light control sensor unit 130 to be lower than the default reference brightness S106).

At this time, the vehicle lighting control system 100 can independently control the headlamp 151, the left brake light 152, and the right brake light 153 as described with reference to FIG. 3 and FIG.

On the other hand, if the condition of any one of steps S102 to S105 is not satisfied (NO), the brightness of the equalizer 150 is controlled to the reference brightness set as default (S107).

Thereafter, the above described vehicle equalization control process can be repeated according to the change of the output of the brake of the vehicle.

As described above, according to the embodiment of the present invention, the brightness of the equalizer is automatically adjusted by judging the real-time traffic information, the vehicle speed information, the rear vehicle presence information and the distance information of the rear vehicle comprehensively without the driver's situation and any other operation So that the convenience of the driver can be increased.

In addition, it is possible to secure the safety of the driver and the neighboring pedestrians by preventing an increase in eye fatigue of the front and rear vehicle driver due to the light of the headlight and the brake light and the occurrence due to the momentary malfunction.

 In addition, by independently reducing the brightness of the lamp in the direction in which the vehicle is present through independent control of the left and right brake lights, it is possible to prevent an accident caused by the dimming of the brake light in a vehicle newly approaching from the rear side.

In addition, there is an advantage that consumption of energy due to reduction in brightness of headlights and brake lights can be reduced.

In addition, by reducing the light generated by a large number of cars in the vehicle stagnation zone, it is possible to prevent light pollution caused by the indiscriminate artificial light use.

In addition, by using existing sensors and equipment, it is possible to reduce the rise in cost and it is easy to supply.

The embodiments of the present invention are not limited to the above-described apparatuses and / or methods, but may be implemented through a program for realizing functions corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded And such an embodiment can be easily implemented by those skilled in the art from the description of the embodiments described above.
