Description

  The present invention relates to a vehicle display system.

  2. Description of the Related Art Conventionally, a function (back view monitor) for displaying a state behind a vehicle such as an automobile on a monitor of a car navigation system is known.

  A vehicle-mounted camera is provided at the rear of the vehicle equipped with this function. For example, when the shift lever disposed in the vehicle interior is put in the R position (reverse position), the state behind the vehicle photographed by the in-vehicle camera is displayed on the monitor of the car navigation system. This allows the driver to recognize the state of the blind spot from the driver, and can assist driving when the vehicle is put in the garage or parallel parking.

JP 2000-177513 A

  When entering the garage or parallel parking, the driver twists his / her face or body to the side or rear of the vehicle, and moves the vehicle backward (reverse) while directly observing the path of the vehicle moving backward (reverse path). Sometimes. The monitor of the car navigation system is usually arranged at the center of the dashboard in the vehicle width direction. Therefore, when the driver moves the vehicle backward while observing the backward path of the vehicle, the monitor showing the state of the rear of the vehicle is not visible to the driver, and in order for the driver to look at the monitor, Since it must be moved greatly, it is not easy to use.

  The objective of this invention is providing the display system for vehicles which can aim at the improvement of the usability of the function which projects the image of the back area of a vehicle at the time of reverse of a vehicle.

  In order to achieve the above object, a display system for a vehicle according to the present invention is arranged at a position different from each other in the vehicle width direction in front of a driver seat of a vehicle and photographing means for photographing a rear region including a course due to the backward movement of the vehicle. A plurality of display means each capable of displaying images taken by the photographing means, a rudder angle obtaining means for obtaining the rudder angle of the steering mechanism of the vehicle, and at least a reverse range of the vehicle. As the rudder angle acquired by the angle acquisition unit is further away from the rudder angle midpoint, the display unit disposed on the downstream side in the direction of the rudder angle is set as an image display target, and the display unit of the image display target is displayed by the photographing unit. Display control means for displaying a photographed image.

  According to this configuration, the plurality of display means are arranged at different positions in the vehicle width direction in front of the driver's seat. Each display means can display an image taken by the photographing means, that is, an image of a rear region including a course when the vehicle moves backward (reverses).

  When the driver moves the vehicle backward while observing the course of the vehicle moving backward, the farther the steering angle of the steering mechanism is from the steering angle midpoint, the farther the driver's line of sight is in the direction of the steering angle from the center of the vehicle. At least in the state where the reverse range of the vehicle is configured, as the steering angle of the steering mechanism is further away from the steering angle midpoint, an image of the rear region of the vehicle is displayed on the display means arranged on the downstream side of the steering angle direction. Is done. As a result, an image of the rear region can be displayed on the display means at a position that is as easy to see as possible by the driver who is viewing the course of the vehicle traveling backward. Therefore, when the vehicle moves backward, the driver can easily view the image in the rear region without moving the line of sight greatly. Therefore, it is possible to improve the usability of the function of projecting an image of the rear area of the vehicle when the vehicle moves backward.

  The vehicle display system may be configured to further include a warning determination unit that determines occurrence of a warning item that should alert the driver. When this configuration is adopted, the display control means, when displaying the image taken by the photographing means on the display means, if the occurrence of a warning item is determined by the attention determination means, the display control means A predetermined alerting image may be displayed on the display means, and an image photographed by the photographing means may be displayed on a display means adjacent to the image display target display means.

  As a result, when a warning item is generated in the vehicle, a warning image is displayed on the display means at a position where the driver can visually recognize it without moving the line of sight greatly. The driver can be recognized well. In addition, since the image of the rear area of the vehicle is displayed on the display means adjacent to the display means on which the alert image is displayed, the driver can easily view the image of the rear area without moving the line of sight greatly. Can do. Therefore, it is possible to improve the usability of the function of displaying an image of the rear area of the vehicle when the vehicle is moving backward while allowing the driver to recognize the occurrence of the alerting matter well.

  Note that the concept of the attention-calling image includes a message (character) that calls attention and a video that calls attention.

  The plurality of display means are, for example, a navigation system monitor (navigation monitor) mounted in the center of the vehicle dashboard in the vehicle width direction, a meter monitor incorporated in an instrument panel (meter panel), and a rearview mirror (room mirror). Two or three or more selected from a rearview mirror monitor provided at the position of the left side mirror and a side mirror monitor provided at the positions of the left and right side mirrors (side outer mirrors).

  ADVANTAGE OF THE INVENTION According to this invention, the usability of the function which displays the image of the back area of a vehicle at the time of reverse of a vehicle can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Electric configuration of vehicle>
FIG. 1 is a block diagram showing an electrical configuration of a vehicle 1 equipped with a display system according to an embodiment of the present invention.

  The vehicle 1 includes a plurality of ECUs (Electronic Control Units) including a CPU and a memory. The plurality of ECUs include a transmission ECU 11 and a display control ECU 12. Each ECU is connected so that bidirectional communication by a CAN (Controller Area Network) communication protocol is possible.

  The vehicle 1 is equipped with, for example, an automatic transmission that automatically changes the gear ratio as a transmission that changes the driving force from the engine. The automatic transmission may be a stepped automatic transmission (AT) or a continuously variable transmission (CVT).

  The transmission ECU 11 mainly controls the automatic transmission.

  Specifically, a shift position sensor 21 is connected to the transmission ECU 11. The shift position sensor 21 outputs a detection signal corresponding to the position of the shift lever S (see FIG. 2) disposed in the vehicle interior. For example, a P position, an R position, an N position, and a D position are provided as shift positions that are positions of the shift lever (select lever). The P position, R position, N position and D position correspond to the P range (parking range), R range (reverse range), N range (neutral range) and D range (drive range) in the automatic transmission, respectively. The shift lever can be shifted between the P position, the R position, the N position, and the D position, and switching of the range can be instructed by the shift operation.

  The transmission ECU 11 changes the range or gear position of the automatic transmission based on information acquired from detection signals of various sensors and / or various information input from other ECUs. A valve (not shown) included in a hydraulic circuit for supplying hydraulic pressure to the valve is controlled.

  The vehicle 1 is provided with a rudder angle sensor 22. The steering angle sensor 22 outputs, for example, a detection signal corresponding to the steering angle (absolute steering angle) with respect to the steering angle midpoint of the steering mechanism. The steering angle detected by the steering angle sensor 22 takes a positive value when the steering wheel operated by the driver is turned to the right from the neutral position, and takes a negative value when the steering wheel is turned to the left. . The steering angle detected by the steering angle sensor 22 may be a steering angle (steering angle) that is a rotation operation angle of the steering wheel, or may be a steering angle of a steered wheel by a steering mechanism. In the following description, the steering angle detected by the steering angle sensor 22 is a steering angle.

  Furthermore, the vehicle 1 is equipped with a plurality of cameras 31 that capture an area outside the vehicle and a plurality of monitors 41 to 45 that display images.

  The display control ECU 12 executes display control for displaying images taken by the camera 31 on the monitors 41 to 45. The display control will be described later.

  The camera 31 has, for example, a rear camera that captures a rear region including a course due to the vehicle 1 moving backward (reverse), and an image equivalent to a mirror image reflected on the rearview mirror (room mirror) as viewed from the driver seated on the driver's seat. Rear camera to shoot, right side camera to shoot image equivalent to mirror image on right side mirror (right side outer mirror) seen from driver seated in driver's seat, and left side seen from driver seated in driver's seat A left side camera that captures an image equivalent to a mirror image reflected on the mirror (left side outer mirror) is included. In addition, the camera 31 may include a vehicle interior camera that captures images of the interior of the vehicle (particularly the rear seat) and a front camera that captures an area in front of the vehicle 1. The camera 31 is composed of, for example, a combination of a color CMOS image sensor and a wide angle lens.

<Monitor layout>
FIG. 2 is a diagram illustrating an example of the layout of the monitors 41 to 45.

  The monitors 41 to 45 are a navigation monitor, a rearview mirror monitor, a meter monitor, a right side mirror monitor, and a left side mirror monitor, respectively, and each includes a liquid crystal panel (liquid crystal display), for example.

  The navigation monitor 41 is a monitor of the car navigation system, and is arranged in the center of the dashboard D in the vehicle width direction (left-right direction).

  The rearview mirror monitor 42 is disposed at a position where the rearview mirror is provided, that is, near the upper end portion of the windshield in the center in the vehicle width direction.

  The meter monitor 43 is disposed at the center in the left-right direction of the instrument panel I.

  The right side mirror monitor 44 is disposed at a position where the right side mirror is provided, that is, outside (right side) near the front end portion of the right front side window.

  The left side mirror monitor 45 is disposed at a position where the left side mirror is provided, that is, outside (on the left side) near the front end portion of the left front side window.

<Display control>
3A, 3B, and 3C are flowcharts showing the flow of processing for display control. FIG. 4 is a diagram showing an example of display on the right side mirror monitor 44. FIG. 5 is a diagram illustrating an example of display on the meter monitor 43 and the right side mirror monitor 44.

  In order to control the display of images on the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44 and the left side mirror monitor 45, the processing shown in FIGS. 3A to 3C is executed by the display control ECU 12. The

  In the processing for display control, the display control ECU 12 checks (confirms) the presence or absence of abnormality in various systems (in-vehicle system) mounted on the vehicle 1 (step S1).

  Specifically, the display control ECU 12 determines whether or not there is an abnormality in the display system including the camera 31, the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45. be able to.

  Further, the display control ECU 12 can control the sonar system and determine whether or not there is an abnormality in the sonar system. The sonar system is an obstacle detection system that detects the presence or absence of an obstacle behind the vehicle 1 using a plurality of ultrasonic sensors (sonar). For example, the plurality of ultrasonic sensors are arranged on the rear bumper of the vehicle 1 at intervals in the vehicle width direction. While the shift lever S is in the R position, the plurality of ultrasonic sensors are turned on in a predetermined order, and ultrasonic waves are transmitted from the ultrasonic sensors that are turned on. If there is an obstacle within the reach of ultrasonic waves from each ultrasonic sensor, the ultrasonic wave hits the obstacle and is reflected, and the reflected ultrasonic wave (reflected wave) is received by the ultrasonic sensor. When the ultrasonic sensor receives the reflected wave, the display control ECU 12 determines the presence or absence of an obstacle within a predetermined range behind the vehicle 1 based on the time from the transmission of the ultrasonic wave to the reception. In the sonar system, when an obstacle exists within a predetermined range, this is warned by sound or the like.

  The presence or absence of an abnormality in the in-vehicle system that is not directly involved in the control of the display control ECU 12 is notified to the display control ECU 12 from the ECU that controls the in-vehicle system. For example, whether there is an abnormality in the brake system of the vehicle 1 is notified from the brake ECU that controls the brake system to the display control ECU 12. In order to check whether there is an abnormality in the in-vehicle system in which the display control ECU 12 is not directly involved in the control, the display control ECU 12 confirms the contents of notification from other ECUs.

  The brake system includes, for example, a brake booster, a master cylinder, a wheel cylinder, and a brake. When a brake pedal provided in the passenger compartment is depressed, the pedaling force input to the brake pedal is transmitted to the brake booster. The pedaling force transmitted to the brake booster is amplified (boosted) by the negative pressure of the brake booster and is input from the brake booster to the master cylinder. In the master cylinder, a hydraulic pressure corresponding to the force input from the brake booster is generated. The hydraulic pressure of the master cylinder is distributed and transmitted to the wheel cylinders provided on each wheel. A braking force is applied from each brake to the wheel by the hydraulic pressure of each wheel cylinder.

  If there is no abnormality in both the brake system and the sonar system of the vehicle 1 as a result of checking whether there is an abnormality in each in-vehicle system (NO in step S2), the display control ECU 12 performs the processing in steps S3 to S14. Is executed.

  That is, it is determined whether or not the current shift position is the R position (step S3).

  If the current shift position is not the R position (NO in step S3), that is, if the shift position is the P position, the N position or the D position, the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, and the right side mirror monitor The normal information is displayed on the left side mirror 44 and the left side mirror monitor 45 (step S4), and the display control process is terminated.

  The normal information means information that should be originally displayed on each of the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45. The normal information of the navigation monitor 41 is information related to navigation or audio. The normal information of the rearview mirror monitor 42 is an image (information behind the vehicle 1) taken by the rear camera 31. The normal information of the meter monitor 43 is guidance information to the driver, such as cumulative travel distance, travel fuel consumption, cruising distance, and outside temperature. The normal information of the right side mirror monitor 44 is an image (information on the right rear of the vehicle 1) taken by the right side camera 31. The normal information of the left side mirror monitor 45 is an image (information on the left rear of the vehicle 1) taken by the left side camera 31.

  If the current shift position is the R position (YES in step S3), the current steering angle is acquired from the detection signal of the steering angle sensor 22 (step S5).

  Further, an image taken by the rear camera 31 on one of the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45, that is, an image of the rear region of the vehicle 1 (hereinafter referred to as the rear view). , “Back view”) is displayed (step S6).

  When the back view is displayed on any of the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45 (YES in step S6), the navigation monitor 41, the rearview mirror monitor 42, at least one of the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45, the amount of change in the steering angle from the point when the display is switched between normal information and non-normal information other than normal information. It is determined whether the angle is 45 ° or more (step S7). This determination suppresses that the display destination of the back view is frequently switched among the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, or the left side mirror monitor 45 according to the steering angle. It is provided for. The numerical value “45 °” is merely an example, and may be appropriately changed to a numerical value that exerts an effect of suppressing frequent switching of the display destination of the back view.

  When the change amount of the steering angle after the display switching is less than 45 ° (NO in step S7), the display on the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45 is displayed. Is not changed, and the processing for display control is terminated.

  On the other hand, the back view is not displayed on any of the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44 and the left side mirror monitor 45 (NO in step S6), or when the display is switched. When the change amount of the steering angle from 45 is 45 ° or more (YES in step S7), it is determined whether or not the current steering angle is in the range of −210 ° to less than 210 ° (step S8).

  When the steering angle is within a range of −210 ° or more and less than 210 ° (YES in step S8), the back view is displayed as non-normal information on the navigation monitor 41 (step S9), and the processing for display control ends. Is done. In this case, the normal information remains displayed on the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45, respectively.

  If the steering angle is outside the range of -210 ° or more and less than 210 ° (NO in step S8), it is then determined whether or not the steering angle is within the range of 210 ° or more and less than 420 ° (step S10). ).

  When the steering angle is in the range of 210 ° to less than 420 ° (YES in step S10), the back view is displayed as non-normal information on the meter monitor 43 (step S11), and the processing for display control is completed. The In this case, the normal information remains displayed on the rearview mirror monitor 42, the right side mirror monitor 44, and the left side mirror monitor 45, respectively. The normal information may be displayed on the navigation monitor 41, or the normal information of the back view or the meter monitor 43 may be displayed, for example.

  If the steering angle is outside the range of 210 ° or more and less than 420 ° (NO in step S10), it is then determined whether or not the steering angle is 420 ° or more (step S12).

  When the steering angle is 420 ° or more (YES in step S11), as shown in FIG. 4, the back view is displayed as non-normal information on the right side mirror monitor 44 (step S13), and display control is performed. Processing is terminated. In this case, the normal information remains displayed on the rearview mirror monitor 42, the meter monitor 43, and the left side mirror monitor 45, respectively. The normal information may be displayed on the navigation monitor 41, or the normal information of the back view or the right side mirror monitor 44 may be displayed, for example.

  If the steering angle is not greater than 420 ° (NO in step S12), the steering angle is less than −210 °. In this case, the back view is displayed as non-normal information on the left side mirror monitor 45 (step S14). Processing for display control is terminated. In this case, normal information may be displayed on the rearview mirror monitor 42, the meter monitor 43, and the right side mirror monitor 44, respectively. The normal information may be displayed on the navigation monitor 41, or the normal information of the back view or the left side mirror monitor 45 may be displayed, for example.

  Note that the maximum amount of rotation to one side of the steering wheel is two and a half, and the maximum and minimum values of the steering angle are 450 ° and −450 °, respectively.

  As a result of checking whether or not there is an abnormality in each in-vehicle system, if an abnormality has occurred in at least one of the brake system and the sonar system of the vehicle 1 (YES in step S2), the display control ECU 12 performs steps S15 to S29. Processing is executed.

  That is, when an abnormality has occurred in at least one of the brake system and the sonar system of the vehicle 1 (YES in step S2), first, a warning message indicating the occurrence of an abnormality is displayed on one of the navigation monitor 41 and the rearview mirror monitor 42. (Step S15).

  Next, it is determined whether or not the current shift position is the R position (step S16).

<Effect>
As described above, the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45 are disposed at different positions in the vehicle width direction in front of the driver's seat. The navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, and the left side mirror monitor 45 can display images taken by the camera 31.

  When the driver moves the vehicle 1 backward while viewing the course of the vehicle 1 moving backward, the farther the steering angle of the steering mechanism is away from the steering angle midpoint, the more the driver's line of sight is in the direction of the steering angle from the center of the vehicle 1. To leave. In a state in which the shift position is the R position and the reverse range of the vehicle 1 is configured, the navigation monitor 41 arranged on the downstream side of the steering angle direction as the steering angle of the steering mechanism is further away from the steering angle midpoint. The rear view is displayed on the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, or the left side mirror monitor 45. As a result, the driver who is viewing the course due to the backward movement of the vehicle 1 backs to one of the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, or the left side mirror monitor 45 at a position as easy as possible to view. A view can be displayed. Therefore, when the vehicle 1 moves backward, the driver can easily view the back view without moving the line of sight greatly. Therefore, it is possible to improve the usability of the function of displaying the back view when the vehicle 1 moves backward.

  Further, when an abnormality occurs in the in-vehicle system, in the state where the reverse range of the vehicle 1 is configured, the steering angle of the steering mechanism is arranged on the downstream side in the direction of the steering angle as the steering angle is further away from the steering angle midpoint. A warning message indicating the occurrence of an abnormality is displayed on one of the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, or the left side mirror monitor 45. Thereby, when an abnormality has occurred in the vehicle 1, the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44, or the position where the driver can visually recognize without moving the line of sight largely. Since a warning message for the occurrence of an abnormality is displayed on one of the left side mirror monitors 45, the occurrence of the abnormality can be well recognized by the driver. In addition, the navigation monitor 41, the rearview mirror monitor 42, the meter monitor 43, the right side mirror monitor 44 or the left side mirror monitor 45 adjacent to one of the navigation monitor 41, the rearview mirror monitor 42, the left side mirror monitor 45, and the meter on which the warning message of occurrence of an abnormality is displayed. Since the back view is displayed on one of the monitor 43, the right side mirror monitor 44, or the left side mirror monitor 45, the driver can easily view the back view without moving the line of sight greatly. Therefore, it is possible to improve the usability of the function of displaying the back view when the vehicle 1 moves backward while allowing the driver to recognize the occurrence of abnormality in the vehicle 1 well.
