Description

Vehicle with traffic light

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle including a traffic light. Particularly, in order for communication between a vehicle and a vehicle, the front vehicle can easily identify a lane by deciding whether the rear vehicle is decelerated through a brake operation state or the like. The present invention relates to a traffic light installed in a vehicle headlight that provides convenience of driving such as changing.

In addition, it is for communication between pedestrians and vehicles, and considering the fact that most of traffic accident deaths occur when walking on crosswalks, the traffic environment needs to be communicated between vehicles and pedestrians to prevent accidents at crossings. Reflected, the traffic light is provided so that the pedestrian can check the vehicle driver's brake operation state (whether the vehicle is in operation or stopped, etc.) from the front, the traffic light is attached to the headlight, and the traffic light is a walking permit signal (green / Red light) and a yellow signal indicating a signal change, and a traffic light installed in a vehicle headlight that allows a pedestrian passing by a pedestrian crossing or other vehicle to predict the course of the vehicle and self-defend.

In general, pedestrian traffic lights are installed in both sidewalks to guide the safety of pedestrians waiting to cross the pedestrian crossing, apart from the traffic control lights that control the vehicle.

However, inadvertently crossing the green traffic light at the crosswalk may cause a traffic accident if the car that is driving violates the traffic laws. For this reason, pedestrians are always walking in an uneasy psychological state because they cannot check the driving conditions of the vehicle and the driver despite the green traffic light and cannot predict the movement of the vehicle.

In particular, as 68.6% of the children who die in traffic accidents are pedestrians, there is a high risk of pedestrian crossings or neighborhoods, and the role of fixed traffic lights is limited for traffic violations.

On the other hand, at the rear of the vehicle, a direction indicator lamp which notifies the driving direction of the vehicle by a blinking operation, a brake lamp which is turned on when the braking device is operated while the vehicle is running, and a brake lamp which notifies the outside, and both sides of the vehicle are repeatedly blinked when driving in an emergency state. Emergency flashing lights are provided.

In particular, the brake light of the vehicle is a lamp device that lights up at the rear of the vehicle in conjunction with the brake pedal that the driver presses for braking while driving, and warns the rear vehicle of the braking state of the front vehicle to maintain a safe distance from the rear vehicle. It is a lamp device that can prevent accidents that can occur accidentally.

For example, when the driver of the front vehicle depresses the brake pedal, the vehicle is turned on by the brake switch, so that the driver of the rear vehicle can easily recognize the braking state and perform safe driving.

However, in addition to the headlights that illuminate the front of the vehicle, there is no separate display device that can know the braking state of the vehicle. Therefore, it is very difficult to anticipate and respond to the course of the vehicle in front of the vehicle.

As described above, a child walking on a crosswalk has a problem of causing traffic accidents that can be prevented due to difficulty in seeing the front of the vehicle and identifying the course of the vehicle.

Therefore, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention includes a traffic light that can pedestrians to determine the movement of the vehicle even in front of the vehicle to safely choose a walking course and self-defense.

The effect to contribute is expected.

Third, when installing a traffic light inside a vehicle, pedestrians may face the driver and the driver may be reluctant to install, but install a signal light near the headlight or fog light to indicate the brake operation status. The driver does not need to be aware of the eyes of the pedestrians.

Fourth, when the driver's seat window is tinted, it is very difficult to check the driver's gaze of the stopped vehicle.The driver's desire to select a walking course safely and to self-defense is determined by judging the movement of the vehicle through the headlights. Meets.

Fifth, a traffic light installed downwardly illuminates a pedestrian passing through the front of the vehicle, escorting the pedestrian, and if necessary, the economical effect of saving the battery by temporarily shutting off the power of the headlight aimed upward is expected.

Sixth, it is possible to check the brake operation state of the rear vehicle, which is difficult to check from the front, even between the running vehicle through the rear view mirror or the side mirror, and the effect of enabling communication between the vehicles is expected.

Seventh, the traffic light is output in the form of a beeping sound, which helps the visually impaired person walking through the vehicle, and the beeping sound is transmitted to another vehicle waiting or to the vehicle waiting in the opposite lane, and even to the driver of the vehicle. It is expected to perform the function of confirming the fact that it is a crosswalk and to prevent the traffic accident.

Lastly, in the case of traffic lenders or parking guides who always have to look in front of the vehicle to guide the vehicle, it is inconvenient to judge the driver's course only through the driver's gaze. This allows more accurate determination and guidance of vehicle movements.

The traffic light of the present invention is composed of two colors (a normal headlight to control the pedestrian's walking and a green light / red light to instruct the pedestrian's walking) or three colors (a yellow light further predicting the mutual conversion of traffic lights). It may be audible or audibly guide the walk. In particular, by equipping the headlights or fog lights such traffic lights can be utilized in existing lighting facilities and can be implemented in combination with the original lighting function.

1 and 2, the vehicle 100 including a traffic light in the headlight includes a driving brake switch 110 and a driving brake switch 110 that are switched by the driving brake pedal 102. And a driving brake driving unit (not shown) for driving the driving brake 112 according to the signal. Herein, the present invention receives a signal light 120 such as a green light or a red light, a signal light controller 130 that receives operation information of the driving brake switch 110, and determines whether to drive the signal light 120, and a signal light controller 130. In accordance with the command of the traffic light 120, the signal light driver 140 for applying power to inform the brake operation state.

The traffic light controller 130 calculates various parameters to be considered in order to operate the traffic light 120 and determines that the traffic light 120 is driven when a predetermined condition is satisfied. The speed of the vehicle may be taken into account to select a driving mode used for the communication between the vehicle and the stop mode used for the communication between the pedestrian and the vehicle.

For example, there may be various conditions that can distinguish the driving mode and the stop mode, but it can be regarded as the stop mode when the speed is maintained at less than 10 km / h. Alternatively, the driving brake driving unit may be constantly operated so that the driving mode may be regarded as a stop mode when the speed is reduced at a constant rate. When the brake operation information is transmitted from the traveling brake switch 110 for a few seconds or more, it may be regarded as a stop mode. The above-described conditions can be determined in combination, and the parameters to be considered below are described in detail.

The traffic light control unit 130 may include a brake operation state information unit 130a. The brake operation state information unit 130a may receive information on the brake operation state from the driving brake switch 110 and determine whether to drive the traffic light 120 in comparison with a reference value.

It may be difficult to confirm that the vehicle is stopped at the crosswalk only by the above-described brake operation state. To this end, the vehicle speed information unit 130b may be further included. The vehicle speed information unit 130b may determine whether the deceleration of the vehicle is in progress for the purpose of stopping by calculating the current speed and the acceleration of the vehicle.

The traffic light control unit 130 may include an RFID information unit 130c. An RFID tag may be installed at the crosswalk and an RFID reader capable of receiving RFID tag information may be installed in the vehicle to determine whether the vehicle has approached the crosswalk through short-range communication. As such, the crosswalk information may be provided using the tag information. In particular, since the tag information has a relatively short recognition range, it is possible to accurately determine whether or not the traffic light operates.

The traffic light control unit 130 may include a GPS information unit 130d. The location information of the vehicle may be used to determine whether the vehicle has approached the crosswalk. A GPS signal may be received from a GPS satellite to provide crosswalk information. Although GPS information is somewhat lower in accuracy than RFID tag information, since most vehicles operate using GPS information, it is easy to combine existing equipment.

The traffic light control unit 130 may include a traffic light information unit 130e. The traffic light information unit 130e may detect a traffic light color pattern installed on a roadway using a color camera, and obtain traffic light information based on a camera image using a database in which a traffic light silhouette and color information are stored. When determining the crosswalk access using the traffic light information, it is possible to determine whether the traffic light blinks and thus provide more accurate crosswalk information.

The traffic light driver 140 may include a green / red LED switch 142 for switching a green / red light and a yellow LED switch 144 for switching a yellow light.

The green / red LED switch 142 includes a switch that is operated when the driver presses the driving brake pedal 102 so that the green / red LED is powered and turned on.

Green LED means green or blue to allow pedestrians to walk, while Red LED indicates red to indicate the brake operation status. Red).

The yellow LED switch 144 is operated when the driver presses and releases the driving brake pedal 102 or, conversely, when the driver presses the pedal without pressing the pedal, thereby turning on and turning on the yellow LED. It includes.

The yellow light is for informing the change of the traffic light 120 when the green light / red light is turned off and then turned off.

The traffic light 120 may be installed in the vehicle headlight assembly H. The headlight assembly H may include a headlight HL and a reflection plate HR, and the traffic light 120 may be mounted on one side of the reflection plate HR. On the other hand, since the headlight is designed to illuminate the front of the vehicle while driving, the illumination direction is installed upward. However, the traffic light of the present invention is installed downward lighting for the safe walking of pedestrians passing through the front.

In another case, although not shown in the figure, the traffic light 120 may be installed inside the fog light assembly.

The vehicle 100 of the present invention may further include a headlight driver 150 for temporarily turning off the headlight HL according to a command of the traffic light controller 130. Therefore, when the traffic light 120 is turned on by the traffic light driver 150, the headlight HL may be turned off by cutting off the power to the temporary headlight HL by the traffic light driver 150. For example, the headlight HL may be turned on when the headlight power cutoff switch 152 is used. On the contrary, when the headlight power cutoff switch 152 is off, the headlight HL may be turned on by releasing the cutoff.

The vehicle 100 of the present invention includes a side brake operation unit 158 that operates a side brake (not shown), a side brake switch 160 that is switched by the side brake operation unit 158, and a side brake switch 160. The speaker driving unit 170 may command a notification sound according to the signal, and a speaker 172 that outputs the notification sound.

When the driver of the vehicle 100 operates the side brake operation unit 158 on the road, it can be regarded as having a will to stop, and thus, the speaker 172 may be used to guide the pedestrian to walk safely.

According to another embodiment of the present invention, the present invention not only provides information necessary for determining whether a pedestrian is walking in the stop mode, but also enables the front vehicle to be provided with driving information of the rear vehicle in the driving mode.

Referring to FIG. 3, the driver of the front vehicle may observe the rear vehicle by the rearview mirror or the side mirror, and may recognize the brake operation state of the rear vehicle by using the mirror or the like. When the speed of the vehicle is decelerated by manipulating the driver brake of the rear vehicle, the front vehicle may recognize this and freely attempt to change lanes.

Referring to FIG. 4, the vehicle 200 of the present invention includes a driving brake driving unit (not shown) for driving the driving brake 212 according to a signal of the driving brake switch 210 switched by the driving brake pedal 202. In the vehicle comprising a brake operation state information unit 230 for generating information on the brake operation state from the traffic light 220, the driving brake switch 210 and compares the reference value with the reference value to determine whether to drive the traffic light 220, And a green / red LED switch 240 for applying power to the signal lamp 220 based on the information. Therefore, when the driving brake 212 of the rear vehicle is operated, the traffic light 220 inside the headlight assembly H is turned on so that the driver of the front vehicle recognizes it and can drive safely.

As described above, the present invention is to use the headlights or the headlights attached to the inside of the fog lights to ensure the pedestrian crossing in peace to establish a traffic order, to determine whether the rear vehicle deceleration in the front vehicle safely By enabling lane change, it can be seen that the technical idea is to prevent traffic accidents. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.
