Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signal change prediction system and a method for estimating a signal change of a traffic light through learning of user experience data,

More particularly, the present invention relates to a system and method for predicting a signal change of a traffic light through learning of user experience data, And more particularly, to a system and method for predicting a signal change of a traffic light through learning of user experience data capable of predicting a signal change of a traffic light on a road and informing a driver thereof.

Generally, roads are equipped with traffic lights installed on roads or at intersections to protect pedestrians crossing the roads or to facilitate the flow of vehicles driving the roads. Drivers can drive the vehicle to drive the roads, When the vehicle enters the vehicle, the operation is performed depending on the traffic signal.

These traffic lights generally consist of a green traffic light that allows the vehicle to go straight ahead or enter into an intersection, a red traffic light to block entry of the vehicle, a yellow traffic light to signal change, and a left turn traffic light to allow the vehicle to enter the left turn direction Therefore, the driver recognizes the traffic light on the crosswalk or each intersection visually and operates the vehicle by judging whether or not the vehicle speed is increased or decreased according to the vehicle flow on the road or other circumstances.

However, although the general traffic light as described above can display traffic signals sequentially by repeatedly lighting and turning off according to a predetermined order, it does not inform the driver of the remaining time until each traffic signal is switched It is difficult for the driver to predict the signal change in advance. In this case, if the green traffic light is illuminated and the vehicle is accelerating to pass through the intersection, the green traffic light is turned off and the vehicle is switched to the yellow traffic light, so the driver must stop the vehicle. Therefore, in case of an unfamiliar driver, a traffic accident such as a collision accident may occur, and fuel consumption due to sudden braking is excessively generated.

In this regard, Korean Patent Publication No. 10-2000-0018157 (published on Apr. 25, 2000) discloses a traffic light such as a traffic light at the intersection or the remaining time of a traffic light on a crosswalk so as to prevent a traffic accident at an intersection A technique relating to the remaining time display device of the present invention is known.

According to this, when the relay driver is driven by the control of the microcomputer and the relay is driven, the corresponding lamp is turned on to serve as a signal lamp. At this time, the counter of the microcomputer counts the frequency generated from the frequency generator, So that the driver or pedestrians of the pedestrian crossing can easily grasp the remaining time and can pass safely.

In addition, the Korean Utility Model Registration No. 20-0264885 (registered on Mar. 02, 2002) discloses a technique relating to an integrated safety signal lamp in which a remaining flashing time of a traffic light is indicated by a numeral, a flashing light, have.

According to this, the auxiliary signal lamp consists of 11 green, 4 green, 4 red, and 4 red flashes and numerals, indicating the flashing time of the signal, and the flashing light is green initially, middle yellow, It is a method to turn off the light in red sequentially. It informs the flashing time by numerical value, and informs the change of signal sequentially by 11 blinking lights, first 4 lights are green, middle 3 lights are yellow, and last 4 lights are red will be.

In addition, the Korean Registered Patent No. 10-1121775 (registered on February 22, 2012) is provided with a predetermined distance from the main signal lamp on the road on which the vehicle is traveling so as to notify the state of the signal lamp of the main signal lamp installed on each road, There is known a technique relating to an auxiliary signal lamp for predicting a signal change and a method of displaying the auxiliary signal for predicting whether or not the vehicle is to be stopped by accurately predicting the remaining time of the green signal as the signal and the notice time of the yellow signal as the stop preliminary signal.

According to the present invention, there is provided an auxiliary signal lamp for signal change prediction and a display method thereof, in which a signal system of an auxiliary signal or the like is indicated to be the same as a main traffic signal so that no confusion occurs in driving the vehicle due to an auxiliary signal , The change time can be predicted when the driver changes from the driving signal to the stop signal at the intersection or the crosswalk, thereby preventing an unexpected progress of the vehicle and an accident caused by sudden braking.

However, these conventional techniques are not only for the driver but also for displaying the remaining time for the green pedestrian traffic light to the pedestrian, which is problematic because the driver can recognize the short time and is not a signal change prediction for the driver In order for the driver to take advantage of this, attention must be paid to the display contents of the pedestrian traffic light, which disadvantageously disperses the driver's attention. Rather, it causes confusion to the driver, There has been a practical problem that an auxiliary device separate from the traffic light has to be attached so that additional investment cost is required.

On the other hand, in general, a driver senses a change situation of a traffic light on the road on a familiar road where he / she travels frequently, predicts a distance to a next traffic light, predicts a signal change situation with respect to a next traffic light, , And driving with sensory signal change prediction is a main cause of traffic accidents.

The method of the present invention comprises the first to fifth steps, and further includes the sixth step .

In the first step, the main control unit 40 drives the GPS receiving unit 10 and the image sensor unit 20 to input position information and traffic signal information from each of them (S110) (S120) of collecting driving information such as position information of the on-road signal lamps on one or more repetitive driving roads along with the driving of the vehicle, and driving order and time information of the map information, . At this time, the traffic signal information collected from the image sensor unit 20 includes at least one of the type and location information of each traffic light, the lighting order and time information such as the individual display of each traffic light, the distance information between each traffic light, Information.

The detailed operation flow of constructing the signal information database in the first step (S120) includes a step (S121) of confirming whether the signal is recognized from the image signal photographed from the image sensor unit (S121) If the result signal is recognized, steps S122 and S124 are performed to distinguish whether the result signal is a green straight-ahead display, a green left-turn display, a yellow attention display, A step S123 of storing the time information and the speed information from the time of green recognition to the time of passing of the traffic lights in the signal information database in the case of the left turn indicator, The order of change of the peripheral signal, the anticipated time of the vehicle stop by the red indicator (the waiting time by the red light, etc.) (S125, S126). In the case of a yellow attention light, the next signal is again searched for a green straight-ahead indicator (S125, S126) (S127-S129) of storing, in a signal information database, a signal change time which is changed from a yellow caution display to a green straight display or a green left turn display in case of a green left turn indicator.

Thus, in the first step, the main control unit 40 inputs position information and traffic signal information from the GPS receiving unit 10 and the image sensor unit 20, and then, when the left turn indicator is recognized, The signal change time information from yellow to green, the signal change order information with respect to the peripheral signal of the intersection when the red light is recognized, and the time information of the red , The signal change time information, the straight-line display of each signal, and the duration information of the left-turn display lamp, and the like, to construct a signal information database.

In the second step, the main controller 40 analyzes the current vehicle location information and the time information, compares the current location information and the time information with the location information and the time information previously stored in the signal information database, and judges from the comparison result that the current vehicle is in a specific time zone / Off time zone) in step S130.

In the third step, the main control unit 40 predicts the signal change order in the corresponding travel route based on the signal information database (S151), and determines a predetermined error rate reference value (for example, The error rate is 5%), the present invention can make the signal change prediction method usable only for the predicted signal change order, thereby reducing the risk of an accident.

The fourth step is carried out when the vehicle is in an operable state as a result of the determination in the third step. The fourth step is a step of driving the individual display lamps for each traffic light in the corresponding traveling route on the basis of the traffic signal information in the current traveling route stored in the signal information database, And calculating and displaying the signal change expected time (S160).

The fifth step is a step executed in succession to the fourth step. The signal change estimated time calculated in the fourth step and the current vehicle speed information, or the signal change estimated time calculated in the fourth step, Based on the collected road situation information, calculates and displays an appropriate speed data that can pass through without stopping at a next expected traffic stop time and a next traffic signal (S170).

In this manner, through the fourth and fifth steps, the main control unit 40 determines the order of driving the individual display lamps and the signal change time for each traffic light in the corresponding traveling route on the basis of the traffic signal information in the current traveling route stored on the signal information database Based on the signal change estimated time information and the current vehicle speed information or the signal change estimated time information, the current vehicle speed information, and the collected road situation information, It is possible to calculate and provide to the driver the appropriate speed data that can be passed without stopping at the next traffic light and the like, so that the driver can be guided to aim for comfortable driving.

The sixth step may be selectively executed according to the initial set value. The step may include a step (S180) of comparing the estimated anticipation time value calculated in the fifth step with a preset reference time value (S180) And a step (S190) of outputting a control signal for stopping the engine to the vehicle body / undercarriage control unit when the expected time value deviates from a preset reference time value.

In the sixth step, for example, when the initial setting value is set to the engine control mode for reducing the fuel consumption, the main control unit 40 determines that the estimated stop time value calculated in the fifth step should be stopped longer than the preset reference time It is possible to automatically output a control signal for turning off the engine to the vehicle body / undercarrier control unit 30 by the engine off control signal transmitted from the main control unit 40, The fuel consumption can be reduced in a case where the vehicle is stopped for a long time by the signal waiting.
