Description

  The present invention relates to a vehicle lamp control system that appropriately controls an illumination range of a vehicle lamp used for illumination of a headlamp or an auxiliary lamp of a vehicle such as an automobile to ensure safe driving.

In order to improve the safety of driving a car, the direction of the driver's face is detected while the car is driving, and the headlamp lighting range of the vehicle is adjusted when the face direction changes. A lamp that is controlled to follow the direction, or controls the lighting of auxiliary lamps such as bending lamps and corner lamps provided in automobiles, thereby ensuring illumination in the area where the driver's face is facing A control system has been proposed. For example, in Patent Document 1, the driver's face is imaged, and the obtained face image is image-analyzed to detect the face direction and the line-of-sight direction. From the detected face direction and line-of-sight direction, the driver's face is detected. There has been proposed a technique for determining the visual intent and changing the irradiation direction of the auxiliary light based on this determination. Further, in Patent Document 2, the direction of the driver's face is detected from the similarly captured face image, and the angle formed by the detected face direction and the vehicle direction at that time (straight direction of the vehicle) is detected. There has been proposed a technique for correcting the deflection of the illumination optical axis of the headlamp in the direction of the face.

  Since the techniques of Patent Documents 1 and 2 are techniques for performing lamp control based on the detected driver's face orientation, various problems may occur when these techniques are actually applied. For example, in Patent Document 1, since the irradiation direction of the auxiliary light is varied based on the face direction and the size of the face direction angle, the driver looks at a direction different from the traveling direction as when the driver looks aside. In some cases, the irradiation direction of the auxiliary lamp may be changed following this. In Patent Document 1, if the change in the orientation of the face is excessive, it is determined that the operation is to confirm the side mirror and the control of the auxiliary light is also excluded. When an object is to be confirmed, the control of the auxiliary light is stopped and it is difficult to confirm the obstacle. Further, in Patent Document 2, since the illumination axis of the headlamp is corrected based on the angle between the face direction and the vehicle (traveling) direction, the driver looks aside as in Patent Document 1. However, the illumination axis of the headlamp will change. In this way, if the direction of the lamp is changed due to a change in the direction of the driver's face that is not directly related to the safe driving of the car, the driver feels bothered or wastes energy. End up. On the other hand, it is no longer possible to control the lighting range that accurately follows the driver's face-facing motion, especially when the area that the driver wants to see and the driving area of the car are insufficiently illuminated. It will be an obstacle to ensuring safety.

  An object of the present invention is to improve visibility for a driver by appropriately controlling the illumination range after detecting vehicle signals related to the driver's face-facing motion and the driving situation of the vehicle, thereby ensuring safe driving of the vehicle. The present invention provides a vehicle lamp control system that can be secured.

A vehicle lamp control system according to the present invention includes a face direction detection unit that detects a face direction operation of a driver of the vehicle, a vehicle signal detection unit that detects a vehicle signal associated with a running state of the vehicle, and a driver's face. The vehicle is determined by turning on / off the auxiliary light based on the determination result of the driving condition determining means based on the determination result of the driving condition determining means and the driving condition determining means for determining the driving condition of the vehicle including at least one of the intersection and the parking lot based on the direction action and the vehicle signal. And a lamp control means for changing and controlling the illumination range of the illumination lamp provided in the. Here, the detection of the face-facing motion in the present invention is detected by a change in the angle formed by the front of the driver's face with respect to the straight traveling direction of the vehicle. Further, the change control of the illumination range of the lamp in the present invention is a change control of the illumination area of the entire vehicle by turning on / off the auxiliary lamp, and simply changing the illumination direction of the lamp as in Patent Document 2. Absent.

According to the present invention, it is determined whether the driving state of the vehicle is at least one of an intersection or a parking lot based on the driver's face-facing motion and a vehicle signal detected in accordance with a change in the driving state of the vehicle. Therefore, the traveling state of the vehicle can be determined with higher reliability than when the traveling state is determined only by the face-facing motion or only by the vehicle signal. The lighting range of the lamp as a whole is changed by controlling the turning on / off of the auxiliary lamp based on the judgment of the driving situation and adding the lighting range of the auxiliary lamp to the lighting range of the existing headlamp and backup lamp. By controlling, the lighting range is automatically controlled so as to illuminate the optimal lighting state for the vehicle driving condition, in particular, the area that the driver wants to visually recognize or illuminate the area to be visually recognized. Therefore, it is possible to set an optimal lighting environment without requiring an operation for the vehicle to improve the visibility for the driver and to ensure the safety of traveling.

  As an embodiment of the present invention, the face orientation detection means, for example, captures the driver's face with an imaging device arranged in front of the driver, analyzes the obtained face image, and analyzes the driver's face orientation. You may comprise so that it may detect. The method of image analysis is not particularly limited. Alternatively, the driver's face orientation may be detected by other methods.

  In the embodiment of the present invention, the vehicle signal detected by the vehicle signal detection means includes at least one of a vehicle speed signal, a steering angle signal, a turn signal signal, and a back signal. Further, the vehicle signal detection means may include a navigation device, and the road information of the surrounding area of the vehicle obtained from the navigation device may be configured as one of the vehicle signals. If the number of vehicle signals is increased, it is possible to deal with the various driving situations of the vehicle, and more accurately determine the driving situation of the vehicle.

As an embodiment of the present invention, when it is determined that the traveling situation determination means is a traveling situation in which the vehicle travels straight after stopping the intersection, the lamp control means lights the left and right side lamps at the same time, and the traveling situation determination means determines the intersection. When it is determined that the vehicle is turning right or left, the lamp control means is configured to light the side lamp in the steering direction of the vehicle in accordance with the driver's face turning to the left or right. Alternatively, the lamp control means turns on the side lamp on the side facing the driver's face when the driving condition determining means determines that the driving condition is parallel parking in the parking lot. In addition, when it is determined that the traveling state determination means is a traveling state in which parking is performed in the parking lot, the lamp control unit is configured to light the left and right side back lamps in accordance with the driver's face being directed backward. To do.

FIG. 1 is a schematic plan view showing a schematic configuration of an automobile to which the lamp control system of the present invention is applied and the illumination range of each lamp, and FIG. 2 is a block diagram showing the system. In FIG. 1, left and right headlamps (headlights) LHL and RHL for illuminating the front of the vehicle are arranged on the left and right of the front part of the car CAR.

It is a characteristic. Further, as shown in FIG. 2, the low beam lamps of the head lamps LHL and RHL swivel control the illumination optical axis in the horizontal and horizontal directions by the control of the swivel (deflection) mechanism SV, and further, the leveling (up and down) mechanism. It is configured such that leveling control of the illumination optical axis in the vertical vertical direction can be performed by control with LV. Since the swivel mechanism and the leveling mechanism are already widely known mechanisms, detailed description thereof is omitted here. In FIG. 1, left and right side lamps LSL and RSL as auxiliary lights for illuminating the left and right front side areas RSA and LSA of the own vehicle are incorporated in each of the headlamps LHL and RHL. On the other hand, existing rear lamps LRL and RRL are provided on the left and right sides of the rear part of the car CAR, respectively. In addition to this, side back lamps LSBL and RSBL, which are auxiliary lights for illuminating the left and right rear areas LSBA and RSBA of the own vehicle, are incorporated in each of the left and right side mirrors of the car CAR. ing.

  On the other hand, in FIG. 1, a face direction detection camera 3 for imaging the face of the driver DR from the front direction is disposed at the front position of the driver's seat in the passenger compartment of the car CAR, for example, in the vicinity of the steering wheel STW. For example, in the vicinity of a room mirror that does not appear in the figure above the windshield, a periphery monitoring camera 4 for imaging a wide area in front of the vehicle is arranged. Each of these cameras 3 and 4 is constituted by a camera using a semiconductor image pickup device such as a CCD image pickup device or a CMOS image pickup device. A navigation device 5 is arranged on the dashboard. From this navigation device 5, the position information on the map where the vehicle is currently traveling, the road information of the area where the vehicle is currently traveling or its surrounding area, especially the curve (curve of the currently traveling road) Road), intersections, slopes, crossings, etc. are output as road signals.

  Further, although not shown in FIG. 1, the car CAR has an on / off state of a lighting switch for turning on the headlamps LHL and RHL, that is, the headlamps LHL and RHL.

Operate the turn signal switch to turn on the left and right turn signal lamps that do not appear Turn sensor 65 for outputting a turn signal signal when the is disposed.

  As shown in FIG. 2, the image signals picked up by the face direction detection camera 3 and the peripheral monitoring camera 4 are input to an image processing ECU (Electronic Control Unit) 1, and the face direction of the driver DR in the image processing ECU 1. Is detected, and road conditions in the front area of the vehicle, particularly obstacles, are detected. Here, the obstacle means an obstacle that is an obstacle to the safe driving of the own vehicle, and is used in a broad sense including, for example, buildings and other foreign objects existing on the road, and other vehicles and pedestrians. The detection signal from the image processing ECU 1 is input to the control ECU 2. The outputs of the sensors 61 to 65 and the navigation device 5 are also input to the control ECU 2. The control ECU 1 determines the current driving situation of the car CAR based on the signals from the image processing ECU 1, the signals from the sensors 61 to 65, and the signal from the navigation device 5, and based on this determination, the headlamp LHL , RHL and backup lamps LBUL, RBUL, as well as low beam lamp LBL swivel control and leveling control, as well as side lamps LSL, RSL and side back lamps LSBL, RSBL as auxiliary lights Execute the control.

  As shown in FIG. 2, the image processing ECU 1 includes a periphery monitoring unit 11 and a face orientation detection unit 12. The periphery monitoring unit 11 captures an image signal captured by the periphery monitoring camera 4 at a predetermined time and recognizes the image, and detects a shoulder of a road ahead of the car CAR and a lane mark drawn on the road. In addition, it detects buildings and foreign objects on the road, and obstacles such as other vehicles and pedestrians. Then, the detected information is output as surrounding monitoring information. The face orientation detection unit 12 captures an image signal of the driver DR face image captured by the face orientation detection camera 3 at a predetermined time timing, recognizes the image, detects the driver's face orientation, and detects the face orientation information. Output as. As described in Patent Documents 1 and 2, there are various methods for detecting the face direction in the face direction detection unit 12, but here, the applicant previously proposed in Japanese Patent Application No. 2007-242941. Is used.

  The face orientation detection operation will be briefly described with reference to FIG. The face direction detection unit 12 performs a Sobel filter process on the face image DRF of the time-series driver DR obtained by imaging at a required time interval with the face direction detection camera 3 to perform the face contour, both eyes, Acquire contours of nose and ears. The face orientation detection camera 3 is disposed in front of the driver DR. Normally, the driver DR can be said to be mostly facing the front of the vehicle, so the driver DR captured face image DRF is captured. Is a front image of the driver's face. Then, make initial settings. In this initial setting, as shown in FIG. 3A, the face image DRF in front of the driver DR is arranged on the determination screen 12A, and the position coordinates of both eyes LE and RE, for example, the center point of the eyeball, from the face image DRF. Position coordinates are calculated, the center point in the horizontal direction of both eyes is calculated from the position coordinates of both eyes, a vertical line passing through the center point is defined as the face center line Cx, and the coordinates of the face center line Cx are stored. Keep it. By performing this initial setting, the position coordinates of both eyes LE and RE are obtained each time from the face image DRF of the driver DR that is sequentially acquired in time series, and these position coordinates and the initial settings are set. From the stored face center line Cx, the dimensions dL and dR of the left and right eyes and the face center line are respectively calculated as displacement dimensions, and the face direction of the driver DR is detected from the displacement dimensions.

  For example, as shown in FIG. 3B, in the face image DRF of the driver DR, when the displacement dimension dL of the left eye LE is larger than the displacement dimension dR of the right eye RE, the driver DR faces left. On the contrary, as shown in FIG. 3C, when the displacement dimension dR of the right eye RE is larger than the displacement dimension dL of the left eye LE, it is detected that it faces right. In addition, the face-facing angle can also be detected from the difference between the deviation dimensions dL and dR of both eyes. Actually, in the initial setting, the correlation between the deviation value difference between the two eyes and the actual face angle of the driver is measured, and the angle using the displacement dimension as a parameter based on the measured value. A map is created and stored in the internal storage device of the face direction detection unit 12, and the deviation direction obtained sequentially is applied to the angle map to quickly detect the face direction and angle of the driver DR. It becomes possible.

  As shown in FIG. 2, the control ECU 2 includes a traveling state determination unit 21 and a lamp control unit 22. The driving condition determination unit 21 receives peripheral monitoring information and face orientation information from the image processing ECU 1, and the plurality of sensors, that is, a headlamp sensor 61, a steering angle sensor 62, a gear position sensor 63, a vehicle speed sensor 64, Each detection signal from the turn sensor 65 is input, and further, position information of the automobile and road information from the navigation device 5 are input. And the driving | running | working condition determination part 22 determines the present driving | running | working condition of a motor vehicle by a predetermined algorithm based on such information and a detection signal. Although the operation for performing this determination will be described later, the travel situation determination unit 21 is provided with the situation map shown in FIG. 4 in advance in order to make a determination, and each input information and detection signal is applied to this situation map. This determines the driving situation. The lamp control unit 22 controls a swivel control unit 23 for swiveling the low beam lamp LBL and a leveling control unit 24 for leveling control based on the traveling state determined by the traveling state determination unit 21. Further, lighting / extinguishing of the side lamps LBL, RBL and the side back lamps LSBL, RSBL are controlled.

  In the lamp control system having the above configuration, the face direction detection camera 3 and the face direction detection unit 12 of the image processing ECU 1 constitute a face direction detection unit of the present invention. Further, the periphery monitoring camera 4, the periphery monitoring unit 11 of the image processing ECU 1, the navigation device 4, and the sensors 61 to 65 constitute vehicle signal detection means of the present invention. Needless to say, the traveling state determination unit 11 of the control ECU 2 is the traveling state determination unit of the present invention, and the lamp control unit 22 is also the lamp control unit of the present invention.

  A lamp control operation by such a lamp control system will be described. FIG. 5 is a main flowchart of the lamp control operation. First, the control ECU 2 determines whether or not the headlamp is lit from the signal of the headlamp sensor in the traveling state determination unit 21 (S11). When it is not lit, lamp control is not executed. If it is lit, a traveling state determination step (S12) is executed. In this traveling state determination step (S12), the traveling state determination unit 21 takes in the peripheral monitoring information and face direction information from the image processing ECU 1 (S121), and at the same time, the steering angle sensor 62, the gear position sensor 63, and the vehicle speed sensor 64. Each detection signal from the turn sensor 65 is fetched (S122), and in some cases, position information and road information from the navigation device 5 are fetched (S123). Is determined (S124). A number of situations can be considered as the running situation to be determined, but in the first embodiment, in order to make the explanation easy to understand, as shown in the situation map of FIG. 4, "intersection", "parking lot", "curve" Three cases are illustrated. In addition, “intersection” illustrates the case of “going straight after temporary stop” and “turn left / right”, and “parking lot” illustrates the case of “parallel parking” and “back parking”. Then, when the traveling state determination unit 21 determines the traveling state, the control ECU 1 executes a lamp control step (S13) in the lamp control unit 22. In this lamp control step (S13), the swivel control unit 23 swivels the illumination optical axis of the low beam lamp LBL in a predetermined direction (S131), and at the same time or independently, the side lamps LSL, RSL and the side back lamps. Control is performed to turn on LSBL and RSBL (S132).

  Hereinafter, the ramp control for each of the “intersection”, “parking lot”, and “curve” driving situations will be described with reference to the situation map of FIG. 4 and FIGS. 6 to 8.

"Intersection: go straight after pausing"
It is recognized from the face direction information from the face direction detection unit 12 that the face of the driver DR is turned to the left and right, and the vehicle speed from the vehicle speed sensor 64 once becomes “0” or lower than the slow speed, but the steering angle sensor The steering angle from 62 is straight-ahead information, and when direction change information from the turn sensor 65 is not input, the vehicle stops at an intersection (including a crossroad or a T-shaped road) and then travels straight at the intersection. Determine the situation. At this time, as schematically shown in FIG. 6A, in addition to illuminating the front area FA with the headlamps LHL and RHL of the automobile CAR, lamp control is performed to illuminate both the left and right sides. Here, the lamp control unit 22 lights the left and right side lamps LSL and RSL simultaneously to illuminate both side areas LSA and RSA. As a result, the optimal brightness and range illumination for confirming other vehicles coming from the left and right that need to be confirmed by the driver at the intersection stop, preceding vehicles and oncoming vehicles, pedestrians, etc. are performed, Visibility by the driver is enhanced, and it is possible to confirm road conditions on the left and right sides of the own vehicle and other vehicles and pedestrians present on the left and right sides of the own vehicle, thereby improving driving safety. At this time, it may be determined with reference to the surrounding information from the surroundings monitoring unit 11 that the vehicle is traveling at an intersection. Similarly, it may be determined from the position information from the navigation device 5 or the road information that the vehicle is traveling at an intersection.

"Intersection: Turn left and right"
The face of the driver DR is directed left and right from the face orientation information, and then directed in a certain direction, the vehicle speed from the vehicle speed sensor 64 is slow or low, and the steering angle from the steering angle sensor 62 is left or right. When changing information is input, and at the same time, the direction change information to the left or right from the turn sensor 65 is input, the car CAR makes a right / left turn at an intersection (including a crossroad or a T-shaped road). It is determined that At this time, as shown in the schematic diagram of FIG. 6 (b), the steering direction of the car CAR, that is, the direction of the input steering angle or the direction of the direction change information as the face of the driver DR is turned to the left and right. Control the lamp to illuminate. In this case, since it is determined that the car CAR is turning right at the intersection, the lamp control unit 22 illuminates the front area FA with the headlamps LHL and RHL, and simultaneously turns on the right side lamp RSL so that the car CAR is in the direction. The right region RSL to be changed is illuminated. This illuminates the road conditions of the destination of the car CAR and other vehicles and pedestrians present at the destination, and illuminates the area that the driver should visually recognize with the optimal brightness and range in order to confirm safety. Visibility by the driver is enhanced, and driving safety is enhanced. In this running state, the swivel control unit 23 may also swivel the illumination optical axis of the low beam lamp LBL in the running direction of the automobile. In this case, the lamp control unit 22 may detect the face angle of the driver DR from the face direction information, and control the swivel angle by matching the swivel angle with the angle of the face of the driver. In this driving situation, the illumination area FA by the headlamps LHL and RHL is also displaced to the right, so that the left side lamp LSL of the car CAR is lit as shown by the broken line in FIG. Then, the left side area LSA may be illuminated together. Further, information from the periphery monitoring unit 11 and information from the navigation device 5 may be referred to together.

“Parking: Parallel parking”
After the driver's face is turned to the left or right, here left from the face orientation information, the vehicle speed from the vehicle speed sensor 64 becomes lower than the slow speed, and the steering angle from the steering angle sensor 62 changes to the left or right, When information to be immediately returned to the straight direction is input, or in some cases, direction change information from the turn sensor 65 is input, the car CAR is in a traveling situation where the car CAR is parked in parallel in a parking space along the shoulder of the road. Is determined. At this time, as schematically shown in FIG. 7A, the lamp control unit 22 illuminates the front area FA of the automobile CAR with the headlamps LHL and RHL, and at the same time the left vehicle facing the driver's face. Lamp control for illuminating the left region LSA with the left side lamp LSL is performed. As a result, it is possible to illuminate the parking space and other vehicles parked in the front and rear with optimum brightness and range, and the visibility for the driver is enhanced, and the wheel is removed from the road shoulder without touching the other adjacent vehicles. It is possible to park the vehicle in the parking space reliably and safely. Further, information from the periphery monitoring unit 11 and information from the navigation device 5 may be referred to together.

"Parking: Back parking"
Information indicating that the face of the driver DR is directed at a large angle to the left or right from the face direction information and facing the rear of the car CAR is input, and back (reverse) information is input from the gear position sensor 63 together with this information. In addition, when the information that the steering angle from the steering angle sensor 62 is greatly changed to the left or right is input, or in some cases, when the direction change information is input from the turn sensor 65, the host vehicle returns to the parking space. It determines with it being the driving | running | working condition to park. At this time, as shown in the schematic diagram of FIG. 7B, the lamp control unit 22 turns on the backup lamps LBUL and RBUL of the own vehicle and turns the parking space of the parking space as the driver's face is turned backward. At the same time as illuminating a certain rear area BA, the left and right side back lamps LSBL, RSBL are turned on to illuminate the left and right rear areas LSBA, RSBA where there are other vehicles adjacent to the parking space. This makes it possible to illuminate the parking space existing in the rear of the car CAR to be visually recognized by the driver and the vicinity thereof with the optimum brightness and range, to improve the visibility by the driver, and to contact other adjacent vehicles. This makes it possible to park the vehicle in the parking space reliably and safely without departing from the parking space. Note that the presence of the car CAR in the parking lot can also be determined by referring to the information from the periphery monitoring unit 11 and the information from the navigation device 5 together.

"curve"
Information indicating that the face of the driver DR is directed to the left or right is input from the face orientation information, and information indicating that the steering angle from the steering angle sensor 62 is gradually changed to the left or right is input together with the information from the vehicle speed sensor 64. When medium-speed or high-speed vehicle speed information is input, it is determined that the vehicle CAR is in a traveling state where the vehicle CAR is traveling on a curve (curved road). At this time, the gear ratio information from the gear position sensor 63 may be referred to. At this time, as shown in the schematic diagram of the right curve in FIG. 8, the lamp control unit 22 illuminates the front area FA in the straight direction of the car CAR with the headlamps LHL and RHL, and the driver's face is left or right. The side of the car CAR facing to the right and the front area of the curved road can be illuminated with optimal brightness and range, and the visibility for the driver is enhanced, and the vehicle speed is suitable for the curve. Safe driving. In this running state, the swivel control unit 23 may perform swivel control with the illumination optical axis of the low beam lamp LBL directed toward a curved road. In this case, the lamp control unit 22 detects the driver's face angle from the face direction information, and controls the swivel angle by matching the swivel angle of the low beam lamp LBL with the angle of the driver DR's face. preferable.

  Here, in each driving situation described above, the driving situation determination unit 21 refers to the position information of the vehicle and the surrounding road information from the navigation device 5 and the surrounding information from the surroundings monitoring unit 11 in an auxiliary manner. Although an example has been described, the determination may be performed using these pieces of information as main information. In particular, the driving status of “intersection”, “parking lot”, and “curve” is determined by the road information and position information from the navigation device, and the vehicle is approaching the intersection, or exists in the parking lot, and further travels on a curved road. Each of these can be determined with high accuracy. Then, by determining the driving situation of the vehicle more specifically based on the driver's face orientation information from the face direction detection unit 12 and the vehicle signals from the sensors 61 to 65, the determination of each driving situation is performed. And the optimum lighting control corresponding to each traveling situation as described above can be realized.

  In the present invention, the face direction detecting means is not limited to the configuration for image analysis of the face image captured by the face direction detecting camera 3 as in the first embodiment as long as it can detect the driver's face direction motion. . Further, the processing method for detecting the face direction by analyzing the driver's face image captured by the face direction detection camera 3 is not limited to the method of the first embodiment, and various processing methods can be adopted.

  In the first embodiment, a steering angle signal, a transmission gear position signal, a turn signal signal, and a vehicle speed signal are used as vehicle signals. In addition, a signal from the navigation device and a peripheral region signal from the peripheral monitoring camera are used. Although it is used, other signals can be appropriately employed in order to determine various traveling situations with higher reliability.

  Further, in the first embodiment, the control ECU 1 includes the leveling control unit 24 that performs leveling control of the low beam lamp LBL. Therefore, the leveling control of the low beam lamp LBL can be effectively performed on the road surface in each driving situation. The illumination range may be changed to perform more optimal illumination range control.
