Description

  The present invention relates to a driving support device that supports a driver of a vehicle based on an image that captures the outside of the vehicle.

  In order to drive a vehicle such as an automobile safely, it is necessary to sufficiently grasp traffic conditions outside the vehicle. Although the driver of the vehicle constantly tries to grasp the surrounding situation while driving, the human sense has a limit. Although vision is particularly important, human vision is limited to the direction the face is facing. In particular, the driver of the vehicle must drive the vehicle under conditions where it is inevitable that a blind spot that cannot be seen behind the vehicle body will occur.

  Regarding the driving of the vehicle, the main parts that are blind spots from the driver are the vicinity of the wheels and the parts immediately before and immediately after the vehicle body. In the vicinity of the wheel, the direction of the wheel itself that changes the traveling direction in accordance with the steering operation cannot be confirmed. Since the steering wheel can be rotated a plurality of times in one direction, even if the steering wheel is apparently in a neutral position, it is not known whether or not it is in a straight traveling state. Also, because the rear view is limited, the driver is very nervous when parking in a narrow space for backward driving.

  Prior art for displaying an image of a rear or side rear view and an expected trajectory on the screen when the vehicle is moving backward is disclosed in, for example, Japanese Patent Laid-Open No. 1-14700. In this prior art, an image of the expected trajectory is displayed on the image obtained by imaging the rear according to the steering angle of the vehicle, so that the confirmation of the steering angle and the safety of the rear can be performed together. it can. Japanese Patent Application Laid-Open No. 7-44799 discloses a prior art that detects the length of a parking space using various sensors and assists driving for parking.

  Prior arts that support driving of a vehicle by capturing an image around the vehicle are disclosed in, for example, Patent Documents 1-7. Patent Document 1 discloses a prior art that detects and displays the possibility of contact with an obstacle from an image captured by a camera. Patent Document 2 discloses a prior art that seamlessly synthesizes and displays a rear image of a vehicle, a left side image, and a right side image. Patent Document 3 discloses a prior art that displays driving images with a distance scale and assists driving. In Patent Document 4, a camera that can be rotated 360 ° horizontally through a rotating head is attached to the ceiling of the vehicle, and a desired direction around the vehicle is imaged, and the captured image is converted and synthesized so that the driver can easily see the image. Prior art for displaying and assisting driving is disclosed. In Patent Document 5, images of the left front, front, and right front of the vehicle are respectively captured by three cameras, and driving assistance is provided by changing the screen division area for displaying the images from the three cameras according to the steering direction. Prior art to do is disclosed. Patent Document 6 discloses a prior art that provides driving assistance by detecting an obstacle from an image captured in front of a vehicle and detecting a gap between the obstacles when the vehicle passes through a narrow road. Patent Document 7 discloses a prior art that performs driving support by switching the display content on the video display from normal display to abnormal display when an abnormal situation occurs.

  1 and 2 show a schematic configuration of a vehicle driving support apparatus according to a first embodiment of the present invention. In the embodiments described below, the same reference numerals are given to the portions corresponding to the configurations of the preceding embodiments, and duplicate descriptions are omitted. The driving assistance device according to the present embodiment performs parking assistance so that the vehicle 1 can accurately park at the parking position partitioned by the white line 3 or the like when the vehicle 1 tries to park in the parking lot 2 backward. . The parking assist displays to the driver of the vehicle 1 on the display screen of the information display 4 which is a display means, a predicted route 5a which is a predicted route or a guideline 5b which extends both sides of the vehicle 1, and driving during parking. Support is provided. The course prediction curve 5 a and the guideline 5 b are generated by a parking assist electronic control unit (hereinafter abbreviated as “parking assist ECU”) 6 based on detection data such as the steering angle, and displayed on the information display 4. . When the driver operates the shift lever 8 of the transmission of the vehicle 1 to switch the traveling direction to the reverse side, the parking assist ECU 6 displays the route prediction curve 5a and the guideline 5b as images on the display screen of the information display 4. . From the speaker 9, warning sound, voice guidance, and the like are reproduced acoustically.

  The information display 4 displays an image captured by the camera unit 10 attached to the rear of the vehicle body of the vehicle 1 along with the course prediction curve 5a and the guideline 5b generated by the parking assist ECU 6. The image captured from the field of view 10a of the camera unit 10 is clearly visible to the driver of the vehicle 1 or becomes a blind spot, and the driving operation in the parking lot 2 is performed together with the course prediction curve 5a and the guideline 5b. Can provide easy-to-understand support.

  The course prediction curve 5 a generated by the parking assist ECU 6 is changed in direction according to the steering operation to the steering 7. The operation of the steering 7 is obtained by detecting the angular displacement amount of the steering shaft 11 by the angle detection sensor 12. In the normal vehicle 1, the steering 7 can be rotated several times. Therefore, the angle detection sensor 12 for detecting the steering angle detects the angular displacement amount and the angular displacement direction of the steering shaft 11, and the center position sensor 13 detects the state where the steering shaft 11 is at the center position.

  The guide line 5b is displayed as a virtual straight line extending backward on both sides of the vehicle body of the vehicle 1 and superimposed on an image captured by the camera unit 10. The direction of the guide line 5b is fixed with respect to the visual field 10a of the camera unit 10. The vehicle 1 is also provided with a conlight sensor 14 that senses ambient brightness and controls the lighting state of the illumination system. The course prediction curve 5a and the guideline 5b displayed on the information display 4 are adjusted to change the brightness and hue according to the brightness of the surroundings of the vehicle 1 detected by the conlight sensor 14 so that the driving assistance can be easily understood. Is done.

  The vehicle 1 is also equipped with in-vehicle devices such as the navigation device 15 and the audio device 16, and displays necessary information using the information display 4. A back sonar 17 and a corner sensor 18 as obstacle sensors are also mounted on the vehicle 1 to detect obstacles present in the blind spot of the vehicle using ultrasonic waves or the like.

  FIG. 3 shows an internal configuration of the parking assist ECU 6 shown in FIGS. 1 and 2. The parking assist ECU 6 includes a digital signal processor (hereinafter abbreviated as “DSP”) 20 that performs overall control. The DSP 20 performs control and signal processing via the bus 21. An image captured by the camera unit 10 is input to an amplifier + filter circuit 22 in the form of an NTSC signal, converted from an analog signal to a digital signal by an analog-digital conversion (hereinafter abbreviated as “ADC”) circuit 23, Stored in the field buffer 24. The video output from the amplifier + filter circuit 22 is also supplied to the sync separation circuit 25, and a sync signal for horizontal synchronization and vertical synchronization is separated and input to the DSP 20.

  The DSP 20 also receives an angle detection signal from the angle detection sensor 12 that detects the angular displacement of the steering shaft 11 and a center position detection signal from the center position sensor 13. The DSP 20 performs a parking assist operation based on the program and data stored in the program memory 27 and the data memory 28 connected to the bus 21, respectively. The storage memory 29 can store the storage contents even when the battery assist is performed and the power supply 35 of the parking assist ECU 6 is not turned on.

  The DSP 20 recognizes the white line 3 and the like based on the input video signal and generates the course prediction curve 5a and the guideline 5b accompanying the steering shaft angular displacement operation. The generated image is stored in field buffers 31 and 32 whose output can be switched by a switch (hereinafter abbreviated as “SW”) circuit 30. The signal is selected by the SW circuit 30 and is provided as a video output from the digital-analog conversion (hereinafter abbreviated as “DAC”) circuit 33 to the information display 4 via the filter + amplifier circuit 34. Power for operation is supplied from the power source 35 to the entire parking assist ECU 6, a reset signal is supplied by the reset circuit 36 when the power is turned on, and the clock signal for adjusting the operation timing to the CLK + frequency dividing circuit 37. Or a signal obtained by dividing the frequency.

  FIG. 4 shows an example of image information for parking assistance displayed on the display screen of the information display 4 in this embodiment. FIG. 4A shows an image corresponding to a state in which the vehicle 1 is going backward and is about to park at the parking position 40. On the rear image, a guide line 5b, which is a line extending in parallel with the vehicle width, is displayed together with a course prediction curve 5a predicted based on the steering angle. In addition, as shown in FIG.4 (b), only the course prediction curve 5a is added and displayed on the back image | video about the parking position 40, or only a back image | video is shown as shown in FIG.4 (c). It can also be switched to display. Alternatively, it is possible to display only the guideline 5b superimposed on the rear image shown in FIG.

  By displaying the guideline 5b, it is possible to know the current vehicle body direction of the vehicle 1 that is executing the parking assist. Further, if the white line 3 is drawn as a parking frame on both sides of the parking position 40, the vehicle 1 can be separated from the space of the parking position 40 by returning the steering 7 to the center position when the white line 3 and the guide line 5b are parallel to each other. The operation of parking in parallel can be easily performed.

  As shown in FIG. 4, the display of the course prediction curve 5a and the guideline 5b can be switched by providing a changeover switch so that the driver can switch the display mode according to his / her preference. Further, automatic control is performed so that the course prediction curve 5a is displayed for a certain period only when a certain driving operation, for example, the steering wheel 7 is operated, and the guideline 5b is displayed for a certain period only when the brake is operated. You can also.

  Further, the brightness and color scheme of the course prediction curve 5a and the guideline 5b are changed according to the brightness of the surroundings of the vehicle 1 sensed by the conlight sensor 14, for example, the display is darkened when the surroundings are dark, It adjusts so that a video and the course prediction curve 5a and the guideline 5b are displayed in a harmonious state. Further, the colors of the course prediction curve 5a and the guideline 5b are also changed so as to be easily understood by the driver according to the surrounding brightness and hue. For example, the surroundings are bright during the daytime, so the colors are conspicuous, such as yellow, and the surroundings are dark at night. If the colors are too conspicuous, the rear image will be difficult to see, so change to a dark and light color.

  The course prediction curve 5a and the guideline 5b use the conlight sensor 14 for changing the brightness and color, and input the ambient brightness. However, a dedicated sensor is provided to detect the brightness. You can also Also, the brightness can be detected from a picture taken by the camera unit 10. When the camera unit 10 captures a color image, the color may be detected from the image, and the color of the course prediction curve 5a and the guideline 5b may be changed according to the detected color.

  When switching the parking assist image as shown in FIG. 4 based on the switch operation from the driver, the state of switching to the beginning of the parking assist operation is the final switching when the previous parking assist operation is performed. The state is stored in the storage memory 29 and set according to the stored contents. Thus, once a switching state that is easy to see for the driver is set, the next parking assist can be performed from the beginning in the switching state that is easy to see.

  FIG. 5 shows a state in which a navigation screen 41 by the navigation device 15 of FIG. 1 and an audio screen 42 for the audio device 16 are displayed on the display screen of the information display 4. When the driver needs, the information display 4 can be used effectively by making it possible to select the rear image of the parking position 40 for parking assistance, the navigation screen 41 or the audio screen 42. it can.

  FIG. 6 shows a state in which an input to the back gear by operating the shift lever 8 of the transmission is notified to the driver via the information display 4. On the rear image showing the parking position 40, a telop 43 such as “back gear” indicating that it is being input to the back gear is displayed for a certain period of time, and the character display of the telop 43 indicates to the driver that the vehicle is in reverse. Can be easily understood. As a result, it is possible to prevent a situation in which the driver forgets the shift position, misidentifies the vehicle as a forward state, and causes an accident due to a sudden start. Instead of the display of the telop 43 or together with the display of the telop 43, the display color of the entire screen can be changed to further alert the driver.

  FIG. 7 shows a state in which the back sonar 17 and the corner sensor 18 are displaying a telop 44 for detecting an obstacle, a telop 45 for parking completion, and a telop 46 for prompting visual confirmation. When the back sonar 17 or the corner sensor 18 detects an obstacle in the vicinity of the vehicle 1, a telop 43 such as “There is an obstacle” or “STOP” indicating that there is an obstacle is displayed for a certain period of time, thereby prompting the driver's attention. . Obstacles detected by the back sonar 17 and the corner sensor 18 should have been captured in the rear image around the parking position 40. If the rear image is watched based on the telop 44, the obstacle 47 can be easily detected. Can be visually recognized. Note that when the obstacle 47 is detected, the display color of the entire screen can be changed instead of the display of the telop 44 or together with the display of the telop 44 to alert the driver.

  The telop 45 indicating completion of parking displays the telop 45 indicating completion of parking when an obstacle sensor such as the back sonar 17 or the corner sensor 18 detects a vehicle stop or a wall and approaches a preset distance. By displaying a telop 45 such as “parking complete” or “STOP”, the driver can be notified of parking completion and a contact accident during reverse travel can be prevented. The telop 46 that prompts visual confirmation is displayed to promote visual safety confirmation when parking assist is executed. By displaying the telop 46, it is possible to prevent a situation in which attention is given to only the information display 4 and attention to the surroundings including the front and sides of the vehicle 1 not reflected on the information display 4 is insufficient.

  Further, in order to improve safety when parked backward, speed control can be performed so that the travel speed of the vehicle 1 does not exceed a certain speed when input to the back gear, for example. The speed control can also be performed when an obstacle sensor such as the back sonar 17 detects the obstacle 47 or the like. By limiting the reverse speed at the time of reverse travel or when detecting an obstacle so as not to exceed a certain speed, it is possible to prevent a collision at the time of reverse movement or to reduce an impact at the time of collision.

  FIG. 8 shows a schematic configuration for performing parking assist in a driving assistance apparatus as a second embodiment of the present invention. In this embodiment, parts corresponding to those in the embodiment of FIG. 1 are denoted by the same reference numerals, and redundant description is omitted. The camera unit 50 according to the present embodiment can change the direction of the visual field 50a by remote control using the remote controller 51. The camera unit 50 is attached to the rear part of the vehicle 1 and is also provided with a backlight 52 for illuminating a visual field 50a captured by the camera unit 50 at night. The backlight 52 illuminates in accordance with the direction of the visual field 50a of the camera unit 50 in conjunction with the remote operation of the camera unit 50 by the remote controller 51. In the present embodiment, not only parking assistance based on images using the information display 4 but also the throttle control 53 and the brake control 54 are performed by the parking assist ECU 56 to assist smooth parking. The information display 4 displays driving support information using the progress prediction curve 55a and the guideline 55b.

  Although the backlight 52 mounted on the vehicle 1 can be used as the backlight 52, as an option, it is preferable to attach a dedicated product corresponding to the camera unit 50 as a retrofit. In particular, when a mechanism for changing the irradiation direction is provided, the option is easier. If the irradiation direction can be changed, for example, when the shift lever 8 of the transmission is operated to enter the back gear, the irradiation direction of the backlight 52 is directed downward, so that visibility can be improved even in the dark such as at night. Can be improved.

  FIG. 9 shows an example of an image for driving support displayed in the embodiment of FIG. In the present embodiment, the guideline 55b is curved and displayed according to the image distortion of the wide-angle camera. The camera used as the camera unit 50 uses a wide-angle lens in order to ensure as wide a visual field 50a as possible. Therefore, in the rear image of the parking position 40 or the like, actually, even a straight portion is imaged as a curved image. Therefore, it is possible to provide more accurate driving assistance by curving the guideline 55b according to the distortion of the image.

  In addition, when a part of the vehicle body of the vehicle 1 such as a bumper is included in the field of view 50a of the wide-angle camera unit 50, the vehicle body is closer to the field. The width of the car body in the video looks larger than the video. As long as the progress prediction curve 55a is displayed in a width corresponding to the width of the vehicle body, the width of the vehicle body is larger in the vicinity of the vehicle body when a part of the vehicle body is visible, as in the guideline 55b. I can see it. In the present embodiment, when the progress prediction curve 55a or the guideline 55b is displayed in correspondence with the vehicle width of the vehicle 1, the portion where the vehicle 1 of the vehicle 1 is close to the vehicle body is hidden, and the portion Judgment will be left to the driver.

  In the portion where the deviation occurs in the vicinity of the vehicle body as described above, the progress prediction curve 55a and the guideline 55b can be widened and displayed continuously on both sides of the vehicle body. The portion of the progress prediction curve 55a or the guideline 55b that is displayed wide is wider than the actual vehicle width. Therefore, if there is no surrounding vehicle or obstacle in the wide display portion, the safety can be ensured more reliably.

  Further, as described above, the guideline 55b is parallel to the side of the vehicle parked at another parking position or the white line drawn to the parking position 40 when the vehicle 1 is parked at the parking position 40. As a result, the vehicle 1 can be parked at the parking position 40 with the steering at the center position.

  Furthermore, the driving support when the vehicle 1 is parked at the parking position 40 can be made easier to understand by setting the width of the guide line 55b to be larger than the actual width of the vehicle 1. For example, the guideline 55b is displayed wider than the actual vehicle width by a certain distance, and the guideline 55b is a white line in the parking position 40, a boundary line with an adjacent parking position, or a vehicle already parked at an adjacent parking position. If the steering is returned to the center position when it is overlapped with the side surface, the steering can be straightened and the vehicle can be parked. In addition, the width | variety which displays the guideline 55b can also be set as the structure which can be set according to the actual conditions, such as a parking lot which users, such as a driver, use regularly. If the parking lot is used regularly, a value suitable for the parking position 40 can be set as a certain distance. When parking lots are not specified, the minimum value necessary for opening and closing the door and entering and exiting is set as a certain distance to ensure that the driver can leave the vehicle 1 after parking. Make sure you do.

  In FIG. 9, the line which shows the stop position 57 of the vehicle 1 is displayed in the vicinity of the vehicle 1 of the guideline 55b. In the rear image, a line is displayed at a certain distance from the rear end of the vehicle 1, and the vehicle is stopped when the line of the parking frame at the parking position 40 reaches that position. As a certain distance, set a value as small as possible so that the bumper at the rear end of the vehicle 1 does not come in contact with an obstacle or a vehicle stop so that parking can be easily performed in a narrow parking space. Is preferred.

  The guideline 55b is displayed with, for example, a dotted line, and is less noticeable than the progress prediction curve 55a. As a result, the progress prediction curve 55a is emphasized as a result, and driving guidance that is easier for the driver to understand can be provided. Further, the length for displaying the guide line 55 b can be changed in conjunction with the back sonar 17. For example, the length of displaying the guide line 55b is shortened according to the alarm stage when the back sonar 17 detects the obstacle 47. As a result, the driver can obtain a guide for the moving distance, and thus can receive driving assistance in a state close to an actual driving feeling.

  FIG. 10 shows a schematic configuration as a vehicle driving support apparatus as a third embodiment which is a premise of the present invention. In the present embodiment, the changeover switch 60 is provided to enable switching between the parallel parking mode or the normal parking mode in which the information display 4 performs the parallel parking support 61 or the normal parking support 62. In the normal parking mode, irradiation of the visual field 50a of the camera unit 50 and the backlight 52 is performed with emphasis on the rear of the vehicle 1. In the parallel parking mode, irradiation of the visual field 50a of the camera unit 50 and the backlight 52 is also performed on the side of the vehicle.

  Note that switching between the parallel parking mode and the normal parking mode can also be performed automatically. For example, the turn signal lamp 63 or the hazard lamp 64 and the operation of the shift lever 8 for putting the transmission into the back gear can be performed on the condition that it is regarded as parallel parking. The navigation device 15 can also refer to map data about the current position of the vehicle 1 and automatically switch to the normal parking mode if the current position is in the parking lot and to the parallel parking mode if the current position is on the road. Further, it is possible to determine whether or not parallel parking is based on a change in the turning angle of the steering wheel 7. For example, in parallel parking, the frequency of changing the steering direction of the vehicle 1 by performing a steering operation by turning back or the like increases. A typical steering operation pattern is stored in the storage memory 29 or the like, and when the operation is performed, it is regarded as parallel parking and is automatically switched to the parallel parking mode.

  FIG. 11 shows a fourth embodiment as a premise of the present invention, in which a plurality of camera units 10 are arranged around the vehicle body of the vehicle 1 and images from the plurality of camera units 10 are displayed side by side on the same screen. The configuration is shown. The camera unit 10 is disposed on each of the front left L, the front right R, and the rear B of the vehicle 1 and captures an image in each field of view 10a.

  FIG. 12 shows an example of screen division when images from a plurality of camera units 10 are simultaneously displayed on the display screen of the information display 4 in the embodiment of FIG.
