Description

Vehicle rear side warning control device and method {ALARM CONTROLLING DEVICE OF VEHICLE AND METHOD THEREOF}

The present invention relates to a vehicle rear-side warning control device and method, and more specifically, to a vehicle rear-side warning control device that warns of the risk of an accident caused by changing lanes by expanding the blind spot detection area according to the vehicle's driving environment. and methods.

Recently, to prevent accidents that occur when a vehicle changes lanes, the Lane Departure Warning System and Blind Spot Detection System have been developed and applied.

In general, a vehicle's side mirror has a blind spot of a certain angle due to the limitations of the driver's visual observation and B-polar, and the vehicle's blind spot is generally defined as an area of 13° to 45° based on the side of the vehicle body. Blind spots that are beyond the detection area of such vehicle's side mirrors are expressed as so-called blind spots. For convenience, in this specification, the non-detection areas of these mirrors are collectively referred to as blind spots. .

Previously, ultrasonic sensors, cameras, etc. were used to detect the presence of obstacles in such blind spots. However, the Blind Spot Detection (BSD) system using existing ultrasonic sensors is meaningful in the normal driving process when the vehicle is parallel to the lane, but when the vehicle suddenly changes lanes and enters, the blind spot detection (BSD) system uses existing ultrasonic sensors, etc. The blind spot detection method had a problem in that it could not function sufficiently.

For example, the detection area recognized by a conventional blind spot detection system (BSD) is set to a certain area behind the user's vehicle, and when another vehicle suddenly enters a specific lane, the blind spot detection area is determined by the user's vehicle. Because it does not extend to the lane next to the vehicle, obstacles attempting to change lanes in the lane next to the vehicle cannot be sufficiently detected.

In other words, since the alarm is only issued when there is a vehicle in the detection area, if another vehicle driving in the lane next to the vehicle outside the detection area and the user's vehicle attempt to change lanes to the same lane at the same time, before the alarm of the vehicle's rear side warning system sounds. There is a high risk of collision between vehicles.

Therefore, there is an urgent need to develop a vehicle rear-side warning system that expands the detection area and warns the user's vehicle in advance when another vehicle driving in the adjacent lane attempts to change lanes.

In order to solve this problem, the purpose of the present invention is to provide a vehicle rear side warning control device that can detect a blind spot by expanding the vehicle's blind spot detection area.

Specifically, the present invention is a vehicle rear side warning control device that significantly reduces the possibility of collision due to lane change by expanding the blind spot detection area according to the driving information of the vehicle driving in the next lane that does not correspond to the blind spot detection area. provides.

The present invention provides an efficient and performance-enhanced vehicle rear-mounted warning control device by selectively controlling the blind spot detection area according to driving information of an approaching vehicle.

In order to achieve the above-described object, in one embodiment of the present invention, a blind spot detection unit that detects the blind spot of the own vehicle using a camera and radar, driving information of the own vehicle, and driving of other vehicles located in the blind spot A driving information receiver that receives information, determines approach information of the other vehicle to the host vehicle based on the driving information of the host vehicle and other vehicles, and transmits two devices in the horizontal direction from the first lane in which the host vehicle is traveling. A vehicle rear side warning control device comprising a control unit that extends the blind spot detection area to a second lane that is more than a lane away from the other vehicle and in which the other vehicle is traveling, and a warning unit that warns the driver of the own vehicle according to the judgment result of the control unit. provides.

In another embodiment of the present invention. A blind spot detection step of detecting the own vehicle's blind spot using a camera and radar, a driving information acquisition step of receiving the own vehicle's driving information and driving information of other vehicles located in the blind spot, the own vehicle and other vehicles Based on the driving information, the approach information of the other vehicle to the own vehicle is determined, and the vehicle is spaced laterally by more than two lanes from the first lane in which the host vehicle is traveling, and extends to the second lane in which the other vehicle is traveling. A vehicle rear side warning control method is provided, including a control step of expanding a blind spot detection area and a warning step of warning the driver of the own vehicle based on driving information of the other vehicle.

As described above, according to the present invention, by expanding the blind spot detection area of the own vehicle to prevent accidents that occur when other vehicles suddenly change lanes, there is an effect of accurately detecting other vehicles approaching the own vehicle. there is.

And since the blind spot detection area is selectively controlled, it has the effect of efficiently reducing the computational processing of the alarm control device.

In addition, it can provide driver safety and convenience by accurately and quickly warning of vehicles located in blind spots.

Figure 1 is a conceptual diagram showing an example of a conventional blind spot detection area and an expanded blind spot detection area according to the present invention.

Figure 1 shows a method of expanding the existing blind spot detection area to the adjacent lane according to the driving conditions of the own vehicle 10 and other vehicles 11 and 12.

Referring to FIG. 1, the host vehicle 10 traveling on the first lane 130 detects other vehicles 11 and 12 located in the blind spot of the host vehicle 10 through cameras, radar sensors, ultrasonic sensors, etc. while driving on the road. ) detects the presence or proximity of At this time, the first other vehicle 11 is driving on the second lane 140, which is two lanes away from the first lane 130, and the second other vehicle 10 is driving on the second lane 140 adjacent to the first lane 130. You are driving in lane 3 (150). To explain FIG. 1 , it is assumed that a first other vehicle 11 attempts to enter the first lane 130 in which the own vehicle 10 is traveling.

Typically, the sensors used in blind spot detection devices have a detection range of a certain distance, such as infrared sensors or ultrasonic sensors, and the control unit of the blind spot detection device determines the blind spot detection area by appropriately adjusting the detection area of these sensors. .

Here, the non-detection area of the mirror of the own vehicle (10) is collectively referred to as a blind spot (120), and the conventional blind spot detection area preset in the rear and side warning system is referred to as the first detection area (100). and the blind spot detection area expanded according to the present invention is denoted as the second detection area 110.

At this time, the preset first detection area 100 only detects the adjacent side lane, but the expanded second detection area 110 detects the side lane as well, so not only the second other vehicle 12 driving in the side lane but also the side next lane It is possible to detect even the first other vehicle 11 attempting to change lanes.

That is, in the conventional rear cross-traffic warning system, the first vehicle 11 driving in the second lane 140, which is a lane next to the first lane 130 in which the own vehicle 10 is traveling, changes lanes and Even though it is moving in the third lane 150, it does not recognize this and does not output a warning to the own vehicle 10, which may cause an accident where vehicles collide with each other.

However, according to the vehicle rear side warning control device according to the present invention, when it is detected that the first other vehicle (11) is trying to change lanes through the turn signal lamp and the measured relative speed of the first other vehicle (11), the rear side It performs blind spot detection and warning functions by changing the first detection area 100, which is the conventional blind spot detection area set in the warning system, to the second detection area 110 extended to the second lane 140. 1 It is possible to accurately detect whether another vehicle (11) is approaching.

Therefore, it has the effect of reducing the risk of accidents by significantly lowering the possibility of collision due to changing lanes of a driving vehicle.

Figure 2 is a block diagram of a vehicle rear side warning control device according to an embodiment of the present invention.

The vehicle rear side warning control device 200 according to the present invention includes a blind spot detection unit 210 that detects the blind spot of the own vehicle using a camera and radar, driving information of the own vehicle, and other vehicles located in the blind spot. A driving information receiver 220 that receives driving information, determines approach information of the other vehicle to the host vehicle based on the driving information of the own vehicle and other vehicles, and determines the approach information of the other vehicle to the host vehicle from the first lane in which the host vehicle is driving. A control unit 230 that is laterally spaced by two or more lanes and extends the blind spot detection area to the second lane in which the other vehicle is driving, and a warning unit that warns the driver of the own vehicle according to the judgment result of the control unit 230. It may include (240).

Referring to FIG. 2, the blind spot detection unit 210 performs the function of detecting blind spots on the rear and sides of the vehicle according to the setting of the blind spot detection area, and includes a camera and radar sensor module, and an ultrasonic sensor module. , It may further include at least one of the infrared sensor modules, but is not limited to this, and any device that can detect blind spots is possible.

Specifically, this blind spot detection unit 210 is a sensor and sensor module used for a general blind spot detection device (BSD, Blind Spot Detection). For example, an emitter is installed in the vehicle to detect electromagnetic waves. Alternatively, ultrasonic waves can be fired to the blind spot, and a receiver (detector) detects the electromagnetic waves or ultrasonic waves that are reflected back from the object to recognize that an object exists in the blind spot.

Additionally, the blind spot detection unit 210 can capture the blind spot of the own vehicle by mounting a camera device, such as a rear view camera, on the left and right side mirrors of the own vehicle. At this time, the captured blind spot image can be transmitted to the warning unit 240 through the control unit 230.

In addition, the blind spot detection unit 210 may additionally include a sensor ECU (Electronic Control Unit) that sets a certain detection range within the area where the sensor can detect. At this time, the blind spot detection area preset in the sensor ECU of the blind spot detection unit 210 is expressed as the first detection area.

The driving information receiver 220 receives driving information of the host vehicle and driving information of other vehicles from various sensors and driving systems mounted on the host vehicle, and the driving information includes the driving speed of the host vehicle and the other vehicle. , may include at least one of the following: driving direction, location information, lane information, and information about whether or not a turn signal lamp mounted on the other vehicle is turned on.

Specifically, among the driving information, the driving speed, driving direction, and location information of the own vehicle can be received from GPS, an acceleration sensor, or a driving system mounted on the own vehicle, and the driving speed, driving direction, and location of the other vehicle. Information can be measured through a radar sensor, ultrasonic sensor, infrared sensor, or camera mounted on the vehicle.

At this time, the driving information receiving unit 220 may be set to receive the driving information of the other vehicle when the other vehicle is within a certain distance range from the own vehicle, where the certain distance range is the blind spot detection. It may be a wider area than the area.

Additionally, among the driving information, lane information may be information about the number of lanes, lane spacing, and lane width on the road on which the own vehicle is traveling. At this time, lane information estimated by the lane keeping assistance system (LKAS) of the own vehicle is received by the driving information receiver 220, or images taken by a camera of the front or side of the vehicle are processed to determine the surroundings of the own vehicle. Lane information identifying the lane may be received by the driving information receiver 220.

In addition, the information about the presence or absence of the turn signal lamp of the other vehicle is information about the turn signal lamp lighting status (ON/OFF) and the left or right turn signal lamp lamp, through which the other vehicle's intention to change lanes and lane change are determined. The direction can be estimated.

In this way, the driving information of the own vehicle and the other vehicle generated from the blind spot detection unit 210 and the driving information receiver 220 is transmitted to the control unit 230 to prevent sudden lane changes of the other vehicle and the own vehicle. The operation of the warning unit 240 can be controlled to quickly warn of the risk of collision.

The blind spot detection area preset by the control unit 230 is the first detection area, and the area in which the blind spot detection area is expanded from the first lane to the second lane spaced laterally by more than two lanes is the second detection area. It can be. At this time, the expanded second detection area is preferably a wider area than the first detection area and the lateral spacing is widened, but it is not limited to this, and the second detection area is more than two lanes apart from the first lane in the lateral direction. The area up to the second lane may be included as the second detection area.

In addition, the control unit 230 sets the blind spot detection area through the driving information received from the blind spot detection unit 210 and the driving information receiver 220. At this time, the other vehicle located in the blind spot of the own vehicle When the turn signal lamp of the vehicle is turned on, the direction indicated by the turn signal lamp is determined, and when the turn signal lamp of the other vehicle is not turned on, the relative speed of the other vehicle with respect to the own vehicle can be calculated in real time.

At this time, if it is determined that the turn signal lamp of the other vehicle indicates the direction of the first lane, the blind spot detection area may be set to the second detection area, and the relative speed of the other vehicle with respect to the own vehicle may be set to the second detection area. If it is greater than the threshold, the blind spot detection area can be set as the second detection area. At this time, the relative speed is a vector value including the magnitude and direction of the relative speed of the other vehicle.

In addition, the control unit 230 determines the entry state of the other vehicle entering the third lane, which is laterally separated by one lane from the first lane in which the host vehicle is traveling, and determines the blind spot according to the determined result. The detection area can be reset to the first detection area or the second detection area. At this time, if the driving time in the third lane after the other vehicle enters the third lane is more than the threshold time, the other vehicle is determined to have entered the complete state, and the blind spot detection area is converted to the first detection area. It can be reset.

And when the blind spot detection area set or reset by the control unit 230 is transmitted to the blind spot detection unit 210, the blind spot detection unit 210 detects the first detection area or A blind spot detection function can be performed using the second detection area.

In addition, the control unit 230 controls the warning unit 240 to display a warning when the turn signal lamp of another vehicle indicates the direction of the first lane or when the other vehicle attempts to enter the direction of the first lane. When the vehicle completes entering the third lane or the turn signal lamp of the other vehicle turns off, the warning display of the warning unit 240 can be controlled to end. Additionally, the control unit 230 may control the vehicle rear side warning control device 200 to operate only when the speed of the own vehicle is 60 km/h or higher.

The warning unit 240 typically outputs an alarm when another vehicle exists within a certain distance of the rear and side blind spot of the own vehicle. At this time, the warning unit 240 refers to a means for outputting a warning in response to a control signal received from the control unit 230 or a component that performs a function corresponding to such means.

Additionally, the warning unit 240 may be implemented with at least one device selected from the group consisting of a voice module, a vibration module, and an image module. For example, a speaker that outputs a warning alarm to warn of the risk of an accident when another vehicle changes lanes, a warning light that is installed on the vehicle's instrument panel and lights up or flashes, and a head-up display that displays a warning image or text on the vehicle's windshield. (Head-Up Display) device, a display device equipped with functions such as navigation that displays the own vehicle and other vehicles on the screen, and is installed on the steering wheel, seat, or accelerator pedal of the vehicle It may be a haptic module that generates vibration.

Specifically, the warning light of the warning unit 240 flashes the left lamp when another vehicle is detected on the left side of the blind spot based on the driver of the own vehicle, and when the other vehicle is detected on the right side of the blind spot. In this case, the right lamp may flash, and the haptic module vibrates on the left side when the other vehicle is detected on the left side of the blind spot based on the driver of the own vehicle, and the haptic module vibrates on the left side when the other vehicle is detected on the right side of the blind spot. In this case, it may vibrate on the right side.

In addition, the warning unit 240 displays a warning when the turn signal lamp of the other vehicle indicates the direction of the first lane or when the other vehicle attempts to enter the direction of the first lane, and the other vehicle moves into the third lane. Once entry is complete, the warning display can end.

In addition, the video module (not shown) of the warning unit 240 detects the blind spot in the blind spot detection area when the turn signal lamp of the other vehicle indicates the direction of the first lane or the other vehicle moves in the direction of the first lane. An image may be generated, and output of the image may be terminated when the other vehicle completes entering the third lane.

In this way, according to the vehicle rear side warning control device 200 of the present invention, when another vehicle driving in the second lane changes lanes and approaches the own vehicle, this is automatically sent to the warning unit 240. By displaying a warning, it improves the driver's driving convenience and reduces the risk of accidents.

According to the vehicle rear side warning control device 200 according to the embodiment of the present invention as described above, the blind spot detection area is expanded according to the driving information of the vehicle driving in the next lane that does not correspond to the blind spot detection area. This has the effect of significantly lowering the possibility of collision due to lane changes.

Figure 3 is a flowchart of a vehicle rear side warning control method according to an embodiment of the present invention.

The vehicle rear side warning control method according to the present invention includes a blind spot detection step of installing at the rear or side of the own vehicle to detect the blind spot detection area of the own vehicle, driving information of the own vehicle, and other vehicles located in the blind spot. A driving information acquisition step of receiving driving information, determining whether the other vehicle is approaching the host vehicle based on the received driving information of the host vehicle and other vehicles, and determining whether the host vehicle is approaching from the first lane in which the host vehicle is driving. A control step of expanding the blind spot detection area to a second lane that is spaced laterally by more than two lanes and in which the other vehicle is driving, and a warning step of warning the driver of the own vehicle based on the driving information of the other vehicle. It can be included.

Referring to FIG. 3, the blind spot detection area is preset as the first detection area (S300). At this time, the first detection area is a blind spot area of the own vehicle including the side lane adjacent to the first lane. Additionally, an area where the blind spot detection area is extended from the first lane to a second lane that is laterally spaced by more than two lanes is a second detection area.

In addition, by executing the operation of the camera and radar sensor in the blind spot detection step (S310), the other vehicle driving in the second lane and approaching the own vehicle is detected, and driving information of the other vehicle is obtained.

At this time, receiving the driving information of the other vehicle may be set to be performed when the other vehicle is within a certain distance range from the own vehicle, where the certain distance range may be an area wider than the blind spot detection area. .

And in the blind spot detection step, driving information of the other vehicle driving in the second lane, which is the blind spot of the host vehicle, is received through the camera and radar sensor, and in the driving information acquisition step, the vehicle mounted on the host vehicle Driving environment information including driving information of the own vehicle and driving information of other vehicles is received from various sensors and driving systems (S320).

At this time, it is determined whether the turn signal lamp of the other vehicle driving in the second lane is turned on based on the driving information of the other vehicle obtained in the control step (S330).

When the turn signal light of the other vehicle is turned on, it is determined whether the turn signal light is a right or left turn signal light, and whether it matches the direction of the first lane (S340).

At this time, if it is determined that the turn signal lamp of the other vehicle indicates the direction of the first lane, the blind spot detection area is set to the second detection area (S350), and the turn signal lamp of the other vehicle is set to the first lane. If it is determined that the direction opposite to the lane is indicated, the blind spot detection area is maintained as the preset first detection area (S300).

On the other hand, when the turn signal lamp of the other vehicle is not turned on, the relative speed of the other vehicle with respect to the own vehicle is calculated in real time (S360).

At this time, it is determined whether the relative speed of the other vehicle with respect to the own vehicle is more than a threshold (S370). If the relative speed is more than the threshold, the blind spot detection area is set as the second detection area (S350), If the relative speed is less than the threshold, the blind spot detection area is maintained as the first detection area (S300).

Here, the relative speed is a vector value including the magnitude and direction of the relative speed of the other vehicle.

Therefore, even in a dangerous situation where the other vehicle changes lanes while the turn signal lamp of the other vehicle is not turned on, the blind spot detection area is expanded by measuring the relative speed of the other vehicle with respect to the own vehicle in real time. By doing so, the risk of accidents can be significantly reduced.

Through the above-mentioned process, the intention of the other vehicle to change lanes can be detected and determined, and a real-time warning of the risk of an accident due to lane change can be displayed to the driver of the own vehicle in the warning stage.

At this time, in the warning step, the warning display may be implemented by at least one device among a voice module, a vibration module, and an image module.

Figure 4 is a flowchart of a vehicle rear side warning control method according to an embodiment of the present invention.

Referring to FIG. 4, the blind spot detection area of the vehicle rear side warning control device 200 of the own vehicle is set to the second detection area according to driving information of the other vehicle driving in the second lane ( S400).

Then, in the blind spot detection step, the camera and radar sensors are operated (S410) to detect another vehicle approaching the own vehicle and obtain driving information of the other vehicle.

And in the control step, the entry completion state of the other vehicle entering the third lane, which is laterally separated by one lane from the first lane in which the host vehicle is traveling, is determined (S420).

At this time, if the other vehicle has entered the third lane, it is determined whether the driving time in the third lane after entering is more than the threshold time (S430), and the time for the other vehicle to drive in the third lane is the threshold time. If it is longer than the time, it is determined that entry into the third lane has been completed, so the blind spot detection area is reset to the first detection area (S440). However, if the driving time of the other vehicle in the third lane is less than the threshold time, it is determined that the other vehicle may attempt to re-enter the first lane or the second lane, and thus the blind spot detection area is determined as Maintain it as the second detection area (S400).

On the other hand, if the other vehicle has not completed entering the third lane, the blind spot detection area is maintained as the second detection area (S400).

In addition, in the control step, if the turn signal lamp of another vehicle indicates the direction of the first lane or the other vehicle attempts to enter the direction of the first lane, the warning unit 240 is controlled to display a warning, and the warning unit 240 is controlled to display a warning. When the vehicle completes entering the third lane or the turn signal lamp of the other vehicle turns off, the warning display of the warning unit 240 can be controlled to end.

Therefore, through the above-described process, the intention of the other vehicle to change lanes can be detected and determined, and accordingly, a warning display can be selectively displayed to the driver of the own vehicle in the warning stage.

As described above, according to the vehicle rear side warning control method of the present invention, in order to prevent accidents that occur when other vehicles suddenly change lanes, the blind spot detection area of the own vehicle is expanded to detect other vehicles approaching the own vehicle. There is an effect that can be detected accurately.

In addition, by selectively controlling the blind spot detection area, it has the effect of efficiently reducing the computational processing of the alarm control device, and provides driver safety and convenience by accurately and quickly warning vehicles located in the blind spot.
