  In the automatic driving vehicle control device, for example, when the driver performs a driving operation (override), the automatic driving is switched to the manual driving. In such an automatic driving vehicle control device, it is usually not notified to a person in the vehicle whether or not automatic driving is in progress. In order to allow the driver to visually recognize that the vehicle is being driven automatically, light emitting elements installed in at least a part of the entire circumference of the steering wheel mounted on the vehicle emit light (for example, Patent Documents). 1).

JP 2014-69671 A

  There is an automatic driving system in which the steering wheel does not rotate in the automatic steering mode. In such an automatic driving system, even if the light emitting element installed on the steering wheel is caused to emit light, the driver does not know how much the steering wheel is currently turned when the manual steering mode is switched. On the other hand, in order to realize seamless switching from the automatic steering mode to the manual steering mode, it is desirable to realize the steering angle of the steering wheel in accordance with the tire turning angle in the automatic steering mode.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a technique for informing a steering angle of a steering wheel in accordance with a tire turning angle in an automatic steering mode.

In addition, an acquisition unit that acquires information on a tire turning angle and a display control unit that displays an assumed steering angle of a steering wheel with respect to the information on the tire turning angle acquired in the acquisition unit are provided. The display control unit also displays the steering angle of the steering wheel within the same field of view of the assumed steering angle of the steering wheel.

  Another aspect of the present invention is a display control method. This method is a display control method in a display control apparatus that can be mounted on a vehicle in which the tire turning angle and the steering angle of the steering wheel are not linked during the automatic steering mode, and acquires information on the tire turning angle. And a step of displaying an assumed steering angle of the steering wheel assumed for the acquired information on the turning angle of the tire. In the displaying step, the steering angle of the steering wheel is also displayed in the same field of view of the assumed steering angle of the steering wheel.

  Note that any combination of the above-described constituent elements and the expression of the present invention converted between an apparatus, a system, a method, a program, a recording medium storing the program, and the like are also effective as an aspect of the present invention.

Example 1
Before describing the present invention in detail, an outline will be described. Embodiment 1 of the present invention relates to a display control device in a vehicle in which a steering wheel does not rotate in an automatic steering mode. Here, an object is to inform the driver of the steering angle of the steering wheel according to the tire turning angle in the automatic steering mode before switching the manual steering mode. The display control apparatus according to the present embodiment, when instructed to switch from the automatic steering mode to the manual steering mode, is a steering wheel steering angle (hereinafter referred to as “assumed steering” Corner)) and the steering angle of the current steering wheel.

  More specifically, the display control device displays an image of the steering wheel (hereinafter referred to as “first steering wheel”) on a HUD (Head Up Display). In the first steering wheel, a portion corresponding to the assumed steering angle is shown in red as an assumed steering angle pointer. The display control device displays an image of another steering wheel (hereinafter referred to as “second steering wheel”) inside the first steering wheel. In the second steering wheel, a portion corresponding to the current steering angle of the steering wheel is shown in red as a steering angle pointer. That is, the angle of the current steering wheel is displayed inside the two images of the steering wheel, and the angle by automatic driving is displayed outside. The driver rotates the steering wheel so that the angle of the rudder angle pointer displayed on the HUD matches the angle of the assumed rudder angle pointer. When the two angles are matched, switching to the manual steering mode is determined.

  FIGS. 1A to 1C show the indoor configuration of the vehicle 100 according to the first embodiment of the present invention. FIG. 1A shows a configuration inside the vehicle 100 in the manual steering mode. This corresponds to a case where the front of the vehicle 100 is viewed from the driver seat. As illustrated, a windshield 12 is disposed in front of the steering wheel 10. In this case, the windshield 12 is not displayed by HUD.

  FIG. 1B shows a configuration inside the vehicle 100 in the automatic steering mode. Here, as in FIG. 1A, the steering wheel 10 and the windshield 12 are arranged. In this case, the first steering wheel 14 is displayed on the windshield 12 by HUD. The first steering wheel 14 has an arc shape, and is shown in black or gray, for example, like the rib portion of the steering wheel 10. Further, an assumed steering angle pointer 16 is shown on the first steering wheel 14. The assumed steering angle pointer 16 is indicated at a position corresponding to the assumed steering angle in the first steering wheel 14. As described above, the assumed steering angle pointer 16 is shown in red, but may not be red as long as it is a color that can prompt the driver to alert the first steering wheel 14. The method for displaying the assumed rudder angle is not limited to the pointer, and any display method that emphasizes the assumed rudder angle may be a mark or a character.

  FIG. 1C shows a process from when the switching from the automatic steering mode to the manual steering mode is instructed (hereinafter, from when the switching from the automatic steering mode to the manual steering mode is instructed until the manual steering mode is switched). 2 shows an internal configuration of the vehicle 100 in a “switching mode”. Here too, the steering wheel 10 and the windshield 12 are arranged in the same manner as in FIGS. In this case, the second steering wheel 18 is also displayed on the windshield 12 by the HUD inside the first steering wheel 14. The second steering wheel 18 has an arc shape concentric with the first steering wheel 14, but the diameter thereof is smaller than the diameter of the first steering wheel 14. Further, the second steering wheel 18 is shown in the same color or a similar color as the first steering wheel 14. Further, a steering angle pointer 20 is shown on the second steering wheel 18. The steering angle pointer 20 is indicated in the second steering wheel 18 at a position corresponding to the actual steering angle of the steering wheel 10. The color of the steering angle pointer 20 is shown in the same manner as the color of the assumed steering angle pointer 16. In such a configuration, the driver rotates the steering wheel 10 so that the steering angle pointer 20 and the assumed steering angle pointer 16 are aligned in the radial direction.

  FIG. 2 shows a configuration of the vehicle 100, and particularly shows a configuration related to automatic driving. The vehicle 100 includes a vehicle control device 30, an automatic driving control device 32, a UI unit 34, a mode changeover switch 36, and a driving operation unit 38. The vehicle control device 30 includes an I / O unit 42 and a processing unit 44, and the processing unit 44 includes a display control device 50, an input unit 52, a determination unit 54, and a switching control unit 56. The display control device 50 includes a first acquisition unit 60, a first generation unit 62, a reception unit 64, a second acquisition unit 66, a second generation unit 68, and a display control unit 70. The automatic operation control device 32 includes an I / O unit 46 and a processing unit 48. The UI unit 34 includes a display unit 40, and the driving operation unit 38 includes the steering wheel 10.

  The display unit 40 visually informs information for the driver, and is a HUD that displays an image on the windshield 12. An example of display by the display unit 40 is shown in FIGS. The display unit 40 may be a display of a car navigation device or a display audio device, or a display of a smartphone or tablet that is installed on a dashboard and operates in conjunction with the vehicle control device 30 described later. May be.

  The steering wheel 10 is an operation unit for steering the vehicle 100. When the steering wheel 10 is rotated by the driver in the manual steering mode, the tire turning angle of the vehicle 100 changes via the steering actuator. The traveling direction of the vehicle 100 is controlled by the change in the tire turning angle of the vehicle 100. The steering actuator can be electronically controlled by a steering ECU (Electronic Control Unit) (not shown). In the automatic steering mode, the tire turning angle and the steering angle of the steering wheel 10 are not linked. That is, in that case, even if the turning angle of the tire changes, the steering wheel 10 does not rotate in conjunction with it or does not rotate at all.

  The mode switch 36 is a switch operated by the driver, and is a switch for switching between the automatic steering mode and the manual steering mode. A switching signal from the mode switch 36 is transmitted to the vehicle control device 30 through a signal line. In addition, the structure which enables mode switching by specific operation with respect to the driving operation part 38, without providing the mode switch 36 may be sufficient. For example, during the automatic steering mode, an operation of rotating the steering wheel 10 in a specific direction by a predetermined amount or more may be a switching operation from the automatic steering mode to the manual steering mode.

  The automatic operation control device 32 is an automatic operation controller that implements an automatic operation control function. The configuration of the processing unit 48 can be realized by cooperation of hardware resources and software resources, or only by hardware resources. Processors, ROM, RAM, and other LSIs can be used as hardware resources, and programs such as an operating system, application, and firmware can be used as software resources. The I / O unit 46 executes various communication controls according to various communication formats.

  The vehicle control device 30 is an HMI (Human Machine Interface) controller for executing an interface function between the vehicle 100 and the driver and a function for determining a driving mode. The processing unit 44 can be realized by cooperation of hardware resources and software resources, or only by hardware resources. Processors, ROM, RAM, and other LSIs can be used as hardware resources, and programs such as an operating system, application, and firmware can be used as software resources. The I / O unit 42 executes various communication controls corresponding to various communication formats. The vehicle control device 30 and the automatic driving control device 32 are directly connected by a signal line. Note that these may be connected via a CAN (Controller Area Network). Further, the vehicle control device 30 and the automatic driving control device 32 may be integrated into one controller.

  The vehicle control device 30 and the steering ECU are connected by wired communication such as CAN or a dedicated line. The steering ECU transmits a state signal indicating the state of the steering wheel 10 to the vehicle control device 30. Further, the automatic driving control device 32 and the steering ECU are also connected by wired communication such as CAN or a dedicated line (not shown). In the automatic steering mode, the steering ECU drives the steering actuator in accordance with a control signal supplied from the automatic driving control device 32. In the manual steering mode, a configuration in which an instruction is directly mechanically transmitted from the steering wheel 10 to the steering actuator may be employed, or a configuration in which electronic control via the steering ECU is interposed may be employed.

  Below, based on the structure demonstrated so far, the process for switching from automatic steering mode to manual steering mode, especially the process for performing a display like FIG.1 (b)-(c) is demonstrated. When the driver operates the mode switch 36 to instruct execution of the automatic steering mode, the mode switch 36 outputs an instruction signal to the I / O unit 42. The I / O unit 42 outputs the input instruction signal to the automatic driving control device 32, so that the automatic driving control device 32 executes the automatic steering mode. Further, the I / O unit 42 outputs an instruction signal to the input unit 52, and the input unit 52 outputs the instruction signal to the reception unit 64. When receiving the instruction signal, the reception unit 64 instructs the display control unit 70 to display in the automatic steering mode. This corresponds to instructing the display as shown in FIG.

  In the case of the automatic steering mode, the automatic driving control device 32 acquires information on the tire turning angle. Since a known technique may be used for this acquisition, description thereof is omitted here. The automatic operation control device 32 outputs information on the tire turning angle to the I / O unit 42. When the information on the tire turning angle is input, the I / O unit 42 outputs the information to the determination unit 54 and the first acquisition unit 60. The first acquisition unit 60 acquires information on the tire turning angle from the I / O unit 42. Since the tire turning angle is sequentially changed by the control of the automatic steering mode in the automatic driving control device 32, the first acquisition unit 60 sequentially acquires information on the tire turning angle. The first acquisition unit 60 outputs information on the tire turning angle to the first generation unit 62.

  The first generation unit 62 inputs information on the tire turning angle from the first acquisition unit 60. The first generation unit 62 stores a table showing the correspondence between the tire turning angle and the assumed steering angle, and the assumed steering angle corresponding to the inputted tire turning angle information while referring to the table. To get. Moreover, the 1st production | generation part 62 produces | generates the image in which the assumed steering angle pointer 16 was shown in the 1st steering wheel 14 like FIG.1 (b). At that time, the assumed rudder angle pointer 16 is arranged at a position corresponding to the obtained assumed rudder angle. Here, FIGS. 3A to 3D are used to describe the processing in the first generation unit 62 in detail.

  FIGS. 3A to 3D show an outline of the operation of the vehicle 100. In particular, FIG. 3A shows the direction of the tire 110 in the vehicle 100, that is, the cutting angle. As illustrated, the cutting angle of the tire 110 is “0 °” in the direction in which the vehicle 100 travels straight. FIG. 3B shows an image generated in the case of FIG. Here, for clarity of explanation, an image displayed on the windshield 12 by the display unit 40 is shown. The first steering wheel 14 is disposed at a fixed position of the windshield 12. Further, the central apex portion of the first steering wheel 14 corresponds to the assumed rudder angle “0 °” corresponding to the turning angle “0 °” of the tire 110, and the assumed rudder angle pointer 16 is shown in that portion.

  FIG. 3B shows a case where the turning angle of the tire 110 is “A ° rightward” from the straight direction. 3B, when the direction of the tire 110 is opposite, the cutting angle of the tire 110 is indicated as “B ° in the left direction”. FIG. 3D shows an image generated in the case of FIG. 3B, and again shows an image displayed on the windshield 12. The assumed steering angle pointer 16 is shown at a position tilted “C ° to the right” from the direction of the assumed steering angle “0 °” in FIG. That is, when the vehicle travels straight, the central top portion of the first steering wheel 14 is shown in red by the assumed steering angle pointer 16, and if the assumed steering angle of the steering wheel 10 changes, the red angle of the assumed steering angle pointer 16 changes by that angle. The position rotates on the first steering wheel 14.

  Further, when the turning angle of the tire 110 is bent “B ° to the left” from the straight traveling direction, the assumed rudder angle pointer 16 is inclined to “D ° to the left” from the direction of the assumed rudder angle “0 °”. Indicated. In the table described above, the turning angle of the tire 110 “A ° in the right direction” and the assumed steering angle “C ° in the right direction” are associated with each other. Further, in the table, the turning angle “B ° in the left direction” of the tire 110 is also associated with the assumed steering angle “D ° in the left direction”. Returning to FIG. The first generation unit 62 outputs the generated image to the display control unit 70.

  The display control unit 70 inputs the image from the first generation unit 62. Further, as described above, the display control unit 70 receives a display instruction in the automatic steering mode from the reception unit 64. In that case, that is, in the automatic steering mode in which no switching instruction is input to the input unit 52, the display control unit 70 causes the display unit 40 to display an image from the first generation unit 62 via the I / O unit 42. That is, the display control unit 70 displays the first steering wheel 14 and the assumed steering angle pointer 16 on the windshield 12 using the HUD. This corresponds to displaying the assumed steering angle of the steering wheel 10.

  Under such circumstances, when the driver operates the mode switch 36 to input a switching instruction from the automatic steering mode to the manual steering mode for the vehicle 100, the mode switching switch 36 displays the switching instruction as I / O. To the unit 42. When the I / O unit 42 outputs the switching instruction to the input unit 52, the input unit 52 inputs the switching instruction. The input unit 52 outputs a switching instruction to the receiving unit 64 and the determining unit 54, and the receiving unit 64 instructs the display control unit 70 to display the switching mode. This corresponds to instructing the display as shown in FIG.

  Even in the switching mode, the first acquisition unit 60 and the first generation unit 62 generate an image showing the first steering wheel 14 and the assumed steering angle pointer 16 by executing the same processing as before. On the other hand, in the switching mode, the steering wheel 10 outputs information related to the steering angle at that time to the I / O unit 42. Even in the switching mode, since the automatic driving control device 32 remains in the automatic steering mode, the turning angle of the tire 110 does not change even when the steering wheel 10 is rotated. When the steering angle information is input from the steering wheel 10, the I / O unit 42 outputs the steering angle information to the determination unit 54 and the second acquisition unit 66. The second acquisition unit 66 acquires information on the steering angle from the I / O unit 42. In addition, since the steering angle is changing sequentially by the rotation of the steering wheel 10 by the driver, the second acquisition unit 66 sequentially acquires information on the steering angle. The second acquisition unit 66 outputs the steering angle information to the second generation unit 68.

  The second generation unit 68 inputs information on the steering angle from the second acquisition unit 66. The 2nd production | generation part 68 produces | generates the image by which the steering angle pointer 20 was shown in the 2nd steering wheel 18 like FIG.1 (c). At that time, the rudder angle pointer 20 is arranged at a position corresponding to the inputted rudder angle. Here, FIGS. 4A to 4F are used to describe the processing in the second generation unit 68 in detail.

  FIGS. 4A to 4F show another outline of the operation of the vehicle 100. In particular, FIG. 4A shows the direction of the tire 110 in the vehicle 100, that is, the cutting angle. Since this is the same as FIG. 3C, description thereof is omitted here. FIG. 4B shows the steering wheel 10 in the situation of FIG. As illustrated, the steering wheel 10 faces the direction in which the vehicle 100 travels straight, and the steering angle at this time is “0 °”. Therefore, in this situation, it can be said that the steering angle of the steering wheel 10 and the turning angle of the tire 110 do not correspond.

  FIG. 4C shows an image generated in the case of FIGS. 4A to 4B. Here, for the sake of clarity, the image displayed on the windshield 12 is shown by the display unit 40, the image generated by the first generator 62, and the image generated by the second generator 68. An image synthesized with an image is shown. The first steering wheel 14 and the assumed steering angle pointer 16 are images generated by the first generation unit 62 and are shown in the same manner as in FIG. On the other hand, the second steering wheel 18 is disposed at a fixed position of the windshield 12 that is inside the arc of the first steering wheel 14. Further, the central vertex portion of the assumed steering angle pointer 16 corresponds to the steering angle “0 °” of the steering wheel 10, and the steering angle pointer 20 is shown in that portion. In such a situation, the assumed steering angle pointer 16 and the steering angle pointer 20 are not aligned in the radial direction of the first steering wheel 14 and the second steering wheel 18.

  FIG. 4D shows the turning angle of the tire 110 in the situation following FIG. Here, in order to clarify the explanation, it is assumed that it is the same as FIG. FIG.4 (e) shows the steering wheel 10 in the condition of FIG.4 (d). The steering wheel 10 indicates a rudder angle tilted “C ° rightward” from the rudder angle “0 °” direction. FIG. 4 (f) shows an image generated in the case of FIGS. 4 (d)-(e). The steering angle pointer 20 is shown at a position tilted “C ° to the right” from the direction of the steering angle “0 °” in FIG. In such a situation, the assumed steering angle pointer 16 and the steering angle pointer 20 are arranged in the radial direction of the first steering wheel 14 and the second steering wheel 18. Returning to FIG. The second generation unit 68 outputs the generated image to the display control unit 70.

  The display control unit 70 inputs the image from the first generation unit 62 and the image from the second generation unit 68. Further, as described above, the display control unit 70 receives a display instruction in the switching mode from the reception unit 64. In this case, that is, when a switching instruction is input to the input unit 52, the display control unit 70 displays the assumed steering angle of the steering wheel 10 and the steering angle of the steering wheel 10 by synthesizing the input images. Generate an image of This corresponds to generating the images of FIGS. 1C, 4C, and 4F. The display control unit 70 displays the synthesized image on the display unit 40 via the I / O unit 42. That is, the display control unit 70 displays the assumed steering angle pointer 16 in the first steering wheel 14 and the steering angle pointer 20 in the second steering wheel 18 on one display unit 40. This corresponds to displaying the steering angle pointer 20 in the same field of view of the assumed steering angle pointer 16.

  The determination unit 54 inputs information on the turning angle of the tire 110 from the automatic driving control device 32 via the I / O unit 42 and information on the steering angle from the steering wheel 10 via the I / O unit 42. input. The determination part 54 acquires the assumed steering angle corresponding to the information on the turning angle of the tire 110 when the switching instruction from the input part 52 is input. For this, a table similar to that of the first generation unit 62 may be used. The determination unit 54 compares the assumed rudder angle with the rudder angle. When the two match, the determination unit 54 determines switching from the automatic steering mode to the manual steering mode for the vehicle 100. Since the assumed steering angle and the steering angle in the determination unit 54 are the same as the assumed steering angle and the steering angle in the display control device 50, the steering wheel 10 displayed by the display control device 50 when the two coincide with each other. This corresponds to the case where the assumed steering angle and the steering angle coincide. The determination unit 54 notifies the switching control unit 56 of the switching determination. Upon receiving the notification from the determination unit 54, the switching control unit 56 instructs the automatic driving control device 32 to switch from the automatic steering mode to the manual steering mode via the I / O unit 42. Thereafter, in the vehicle 100, the manual steering mode is executed.

  The operation of the vehicle 100 configured as above will be described. FIG. 5 is a flowchart showing a switching procedure by the vehicle 100. When it is an automatic steering mode (Y of S10), the 1st acquisition part 60 acquires the information on the turning angle of tire 110 (S12). The 1st production | generation part 62 calculates the assumption steering angle of the steering wheel 10 from the information of the turning angle of the tire 110 (S14). The display control unit 70 displays the assumed steering angle of the steering wheel 10 on the HUD (S16). If the mode changeover switch 36 is depressed (Y in S18), the second acquisition unit 66 acquires the current steering angle of the steering wheel 10 (S20). The display control unit 70 displays the current steering angle of the steering wheel 10 on the HUD (S22).

  When the assumed steering angle of the steering wheel 10 matches the current change in the steering angle of the steering wheel 10 (Y in S24), the determination unit 54 determines to switch from the automatic steering mode to the manual steering mode (S26). . When the assumed steering angle of the steering wheel 10 does not match the current change in the steering angle of the steering wheel 10 (N in S24), the process returns to step 20. If it is not the automatic steering mode (N in S10), Step 12 to Step 26 are skipped. If the mode switch 36 is not depressed (N in S18), Step 20 to Step 26 are skipped.

  According to the present embodiment, since the steering angle pointer is also displayed in the same field of view of the assumed steering angle pointer, the steering angle of the steering wheel according to the tire turning angle in the automatic steering mode can be notified. Further, since the assumed rudder angle pointer and the rudder angle pointer are displayed together from the HUD, both confirmations can be facilitated. Further, since the switching from the automatic steering mode to the manual steering mode is determined when the assumed steering angle pointer and the steering angle pointer match, seamless switching can be realized. Further, since the assumed steering angle pointer and the steering angle pointer are displayed in association with each other, it is easy to understand how much the steering wheel can be smoothly switched when switching to the manual steering mode. Further, since the display content is changed depending on whether or not a switching instruction is input, display according to the situation can be realized.

(Example 2)
Next, Example 2 will be described. As in the first embodiment, the second embodiment also relates to a display control device in a vehicle in which the steering wheel does not rotate in the automatic steering mode. The second embodiment is also intended to notify the driver of the steering angle of the steering wheel in accordance with the tire turning angle in the automatic steering mode before the manual steering mode is switched. In the first embodiment, the assumed rudder angle and rudder angle are displayed on the HUD. On the other hand, in the second embodiment, these displays are different from the first embodiment. Here, it demonstrates centering on the difference from before.

  FIGS. 6A to 6C show the indoor configuration of the vehicle 100 according to the second embodiment of the present invention. FIG. 6A shows an in-vehicle configuration of the vehicle 100 in the manual steering mode. This corresponds to the case where the front of the vehicle 100 is viewed from the driver's seat, as in FIG. As illustrated, a windshield 12 is disposed in front of the steering wheel 10. In this case, the windshield 12 is not displayed by HUD. Moreover, the light emission part 22 is attached to the center vertex part at the time of directing the steering wheel 10 to a straight ahead direction. The light emitting unit 22 is turned off in the manual steering mode.

  FIG. 6B shows a configuration inside the vehicle 100 in the automatic steering mode. Here, as in FIG. 1B, the first steering wheel 14 is displayed on the windshield 12 by HUD, and the assumed steering angle pointer 16 is shown on the first steering wheel 14. Moreover, the light emission part 22 is light-extinguished similarly to Fig.6 (a).

  FIG. 6C shows a configuration inside the vehicle 100 in the switching mode. Here, as in FIG. 6B, the first steering wheel 14 is displayed on the windshield 12 by HUD, and the assumed steering angle pointer 16 is shown on the first steering wheel 14. On the other hand, the light emitting unit 22 is turned on. Accordingly, the light emitting unit 22 also rotates according to the rotation of the steering wheel 10. Here, the rotation angle of the steering wheel 10 and the rotation angle of the light emitting unit 22 are the same. Therefore, it can be said that the light-emitting portion 22 that is lit indicates the steering angle of the steering wheel 10, similarly to the steering angle pointer 20 described above. In such a configuration, the driver rotates the steering wheel 10 so that the light emitting unit 22 and the assumed steering angle pointer 16 are aligned in the radial direction.

  FIG. 7 shows a configuration of the vehicle 100, and particularly shows a configuration related to automatic driving. The vehicle 100 includes a vehicle control device 30, an automatic driving control device 32, a UI unit 34, a mode changeover switch 36, and a driving operation unit 38. The vehicle control device 30 includes an I / O unit 42 and a processing unit 44, and the processing unit 44 includes a display control device 50, an input unit 52, a determination unit 54, and a switching control unit 56. The display control device 50 includes an acquisition unit 80, a generation unit 82, a reception unit 64, and a display control unit 70. The automatic operation control device 32 includes an I / O unit 46 and a processing unit 48. The UI unit 34 includes the light emitting unit 22 and the display unit 40, and the driving operation unit 38 includes the steering wheel 10.

  The light emitting unit 22 is attached to the steering wheel 10 as shown in FIGS. For example, an LED (Light Emitting Diode) is used for the light emitting unit 22, but is not limited thereto. The light emitting unit 22 is turned off in the automatic steering mode and the manual steering mode, and turned on in red in the switching mode.

  Below, based on such a structure, the process for switching from an automatic steering mode to a manual steering mode, especially the process for performing a display like FIG.6 (b)-(c) is demonstrated. When the driver operates the mode changeover switch 36 to instruct execution of the automatic steering mode, the instruction signal is sent from the mode changeover switch 36, the I / O unit 42, the input unit 52, and the reception unit 64 as before. It is transferred in order. When receiving the instruction signal, the reception unit 64 instructs the display control unit 70 to display in the automatic steering mode. This corresponds to instructing the display as shown in FIG.

  Since the process in the automatic steering mode is the same as before, the description thereof is omitted here. The acquisition unit 80 and the generation unit 82 correspond to the first acquisition unit 60 and the first generation unit 62 in FIG. The display control unit 70 inputs the image from the generation unit 82. Further, the display control unit 70 receives a display instruction in the automatic steering mode from the reception unit 64. In that case, the display control unit 70 causes the display unit 40 to display the image from the generation unit 82 via the I / O unit 42. This display is as shown in FIG.

  Under such circumstances, when the driver operates the mode switch 36 to input a switching instruction from the automatic steering mode to the manual steering mode for the vehicle 100, the mode switching switch 36 sends the switching instruction to the I / O unit. The I / O unit 42 outputs a switching instruction to the input unit 52. The input unit 52 outputs a switching instruction to the receiving unit 64 and the determining unit 54, and the receiving unit 64 instructs the display control unit 70 to display the switching mode.

  Even in the switching mode, the acquisition unit 80 and the generation unit 82 generate an image showing the first steering wheel 14 and the assumed steering angle pointer 16 by executing the same processing as before. On the other hand, in the switching mode, the display control unit 70 turns on the light emitting unit 22 via the I / O unit 42. Thus, the display control unit 70 is the light emitting unit 22 for displaying the assumed steering angle of the steering wheel 10 on the display unit 40 and indicating the steering angle of the steering wheel 10, and is provided in the steering wheel 10. The light emitting unit 22 is turned on. Here, FIGS. 8A to 8D are used to describe the processing in the switching mode in detail.

  FIGS. 8A to 8D show an outline of the operation performed by the vehicle 100. In particular, FIG. 8A shows the direction of the tire 110 in the vehicle 100, that is, the cutting angle. Since this is the same as FIG. 3C, description thereof is omitted here. FIG. 8B shows an image generated in the case of FIG. Here, for the sake of clarity, the display unit 40 shows an image displayed on the windshield 12 and the steering wheel 10 in which the light emitting unit 22 is lit. The first steering wheel 14 and the assumed steering angle pointer 16 are shown in the same manner as in FIG. In addition, the steering wheel 10 faces the direction in which the vehicle 100 goes straight. Therefore, the rudder angle indicated by the light emitting unit 22 that is lit is “0 °”. In this situation, it can be said that the steering angle of the steering wheel 10 and the turning angle of the tire 110 do not correspond.

  FIG. 8C shows the cutting angle of the tire 110 in the situation following FIG. Here, the cutting angle is assumed to be the same as in FIG. 8A for the sake of clarity. FIG. 8D shows an image generated in the case of FIG. Since the turning angle of the tire 110 is not changed compared to the case of FIG. 8B, the first steering wheel 14 and the assumed steering angle pointer 16 are shown in the same manner as in FIG. 8B. On the other hand, the steering wheel 10 is inclined “C ° to the right” from the direction of the steering angle “0 °”. Therefore, the rudder angle indicated by the light emitting unit 22 that is lit is “C ° in the right direction”. In such a situation, the assumed steering angle pointer 16 and the light emitting unit 22 are arranged in the radial direction of the steering wheel 10 and the first steering wheel 14. Returning to FIG. Subsequent processes of the determination unit 54 and the switching control unit 56 are the same as those described above, and thus description thereof is omitted here.

  The operation of the vehicle 100 configured as above will be described. FIG. 9 is a flowchart showing a switching procedure by the vehicle 100. When the automatic steering mode is set (Y in S50), the acquisition unit 80 acquires information on the turning angle of the tire 110 (S52). The generation unit 82 calculates the assumed steering angle of the steering wheel 10 from information on the turning angle of the tire 110 (S54). The display control unit 70 displays the assumed steering angle of the steering wheel 10 on the HUD (S56). If the mode changeover switch 36 is depressed (Y in S58), the display control unit 70 turns on the light emitting unit 22 in red (S60).

  When the assumed steering angle of the steering wheel 10 matches the current movement of the steering wheel 10 (Y in S62), the determination unit 54 determines to switch from the automatic steering mode to the manual steering mode (S64). . If the assumed steering angle of the steering wheel 10 does not match the current movement of the steering wheel 10 (N in S62), the process returns to step 60. If it is not the automatic steering mode (N in S50), Step 52 to Step 64 are skipped. If the mode switch 36 is not depressed (N in S58), step 60 to step 64 are skipped.

  According to the present embodiment, since the light emitting unit is also displayed within the same field of view of the assumed steering angle pointer, it is possible to notify the steering angle of the steering wheel according to the turning angle of the tire in the automatic steering mode. In addition, when the assumed steering angle pointer matches the light emitting unit, switching from the automatic steering mode to the manual steering mode is determined, so that seamless switching can be realized. In addition, since the steering wheel may be rotated so as to match the display of the assumed steering angle pointer, the operation by the driver can be facilitated.

(Example 3)
Next, Example 3 will be described. The third embodiment also relates to a display control device in a vehicle in which the steering wheel does not rotate in the automatic steering mode, as before. The third embodiment is also intended to notify the driver of the steering angle of the steering wheel in accordance with the tire turning angle in the automatic steering mode before the manual steering mode is switched. In Example 3, the display for informing the driver of the steering angle of the steering wheel according to the turning angle of the tire is different from the conventional display. Here, it demonstrates centering on the difference from before.

  FIGS. 10A to 10C show the indoor configuration of the vehicle 100 according to the third embodiment of the present invention. FIG. 10A shows a configuration inside the vehicle 100 in the manual steering mode. This corresponds to the case where the front of the vehicle 100 is viewed from the driver's seat, as in FIG. As illustrated, a windshield 12 is disposed in front of the steering wheel 10. A plurality of light emitting elements 26 are arranged at substantially equal intervals along the outer diameter of the rim portion of the steering wheel 10. In addition, a light emission band 24 is formed by the plurality of light emitting elements 26. In the manual steering mode, since the plurality of light emitting elements 26 are all turned off, it can be said that the light emitting band 24 is turned off. Further, the light emitting unit 22 is attached to the central apex portion when the steering wheel 10 is directed in the straight traveling direction and to the inner diameter side of the steering wheel 10. In the manual steering mode, the light emitting unit 22 is also turned off.

  FIG. 10B shows a configuration inside the vehicle 100 in the automatic steering mode. Here, one of the plurality of light emission bands 24 forming the light emission band 24 is lit. If it demonstrates concretely, the light emitting element 26 of the position corresponding to an assumed steering angle will light. On the other hand, the light emitting unit 22 is turned off.

  FIG. 10C shows the configuration inside the vehicle 100 in the switching mode. Here, the light emitting unit 22 is turned on. Accordingly, the light emitting unit 22 also rotates according to the rotation of the steering wheel 10. As described above, since the rotation angle of the steering wheel 10 and the rotation angle of the light emitting unit 22 are the same, it can be said that the lighted light emitting unit 22 indicates the steering angle of the steering wheel 10. Similarly to FIG. 10B, the light emitting element 26 at the position corresponding to the assumed steering angle among the plurality of light emitting bands 24 forming the light emitting band 24 is turned on. Here, even if the steering wheel 10 rotates, if the turning angle of the tire 110 is constant, the light emitting element 26 to be turned on is switched so that the light emitting element 26 corresponding to the assumed steering angle is turned on. Go. In such a configuration, the driver rotates the steering wheel 10 so that the light emitting unit 22 and the lit light emitting element 26 are aligned in the radial direction.

  FIG. 11 shows a configuration of the vehicle 100, and particularly shows a configuration related to automatic driving. The vehicle 100 includes a vehicle control device 30, an automatic driving control device 32, a UI unit 34, a mode changeover switch 36, and a driving operation unit 38. The vehicle control device 30, the automatic driving control device 32, and the driving operation unit 38 are configured in the same manner as in FIG. The UI unit 34 includes a light emitting unit 22 and a light emitting band 24.

  The light emission band 24 includes a plurality of light emitting elements 26 and is attached to the steering wheel 10 as shown in FIGS. For example, an LED is used for each light emitting element 26, but is not limited thereto. The plurality of light emitting elements 26 are turned off in the automatic steering mode and the manual steering mode. On the other hand, one of the plurality of light emitting elements 26 lights red in the switching mode.

  In the following, based on such a configuration, a process for switching from the automatic steering mode to the manual steering mode, particularly a process for performing display as shown in FIGS. 10B to 10C will be described. When the driver operates the mode changeover switch 36 to instruct execution of the automatic steering mode, the instruction signal is sent from the mode changeover switch 36, the I / O unit 42, the input unit 52, and the reception unit 64 as before. It is transferred in order. When receiving the instruction signal, the reception unit 64 instructs the display control unit 70 to display in the automatic steering mode. This corresponds to instructing the display as shown in FIG.

  In the automatic steering mode, the acquisition unit 80 acquires information on the turning angle of the tire 110 from the automatic driving control device 32 via the I / O unit 42. The acquisition unit 80 acquires information on the steering angle from the steering wheel 10 via the I / O unit 42. The acquisition unit 80 outputs information on the turning angle of the tire 110 and information on the steering angle to the generation unit 82. The generation unit 82 inputs information on the turning angle of the tire 110 and information on the steering angle from the acquisition unit 80. The generation unit 82 acquires an assumed steering angle corresponding to information on the turning angle of the tire 110. For this, a table similar to that of the first generation unit 62 described above may be used.

  The generation unit 82 derives a relative steering angle (hereinafter referred to as “relative steering angle”) by subtracting the steering angle from the assumed steering angle. The relative rudder angle is a rudder angle with respect to the central apex portion of the steering wheel 10 when the steering wheel 10 faces in the straight traveling direction of the vehicle 100. It can be said that this is the steering angle based on the portion where the light emitting unit 22 is disposed. Hereinafter, the central vertex portion of the steering wheel 10 when the steering wheel 10 faces in the straight traveling direction of the vehicle 100 is referred to as a “reference portion”. When the steering wheel 10 is rotating, the reference portion also rotates, but the steering angle from the rotated reference portion is the relative steering angle.

  Moreover, the production | generation part 82 memorize | stores the table which matched the some light emitting element 26 and the relative steering angle. In the table, for example, the light emitting element 26 arranged in the reference portion, that is, the light emitting element 26 arranged in parallel with the light emitting unit 22 is associated with the relative steering angle “0 °”. The generation unit 82 selects the light emitting element 26 corresponding to the derived relative steering angle while referring to the table. If the derived relative rudder angle is not included in the table, the light emitting element 26 corresponding to the relative rudder angle closest to the derived relative rudder angle is selected. The generation unit 82 outputs information regarding the selected light emitting element 26 to the display control unit 70.

  The display control unit 70 inputs information regarding the light emitting element 26 from the generation unit 82. Further, the display control unit 70 receives a display instruction in the automatic steering mode from the reception unit 64. In that case, the display control unit 70 turns on the light emitting element 26 corresponding to the information received from the generation unit 82 via the I / O unit 42.

  FIGS. 12A to 12D are used to describe the processing in the generation unit 82 and the display control unit 70 in more detail. 12A to 12D show an outline of operations performed by the vehicle 100. FIG. FIG. 12A is the same as FIG. 3A and shows a case where the cutting angle of the tire 110 is “0 °”. FIG. 12B shows a case where the cutting angle of the tire 110 is “0 °” and the steering wheel 10 faces in the straight traveling direction of the vehicle 100. Since the turning angle of the tire 110 is “0 °”, the assumed steering angle is also “0 °”. Further, since the steering angle of the steering wheel 10 is “0 °”, the relative steering angle is also “0 °”. Therefore, only the light emitting element 26 arranged in the reference portion is turned on. In FIG. 12A, the light emitting element 26 arranged in the reference portion is indicated as “P”.

  FIG.12 (c) is shown similarly to FIG.3 (b), and shows the case where the cutting angle of the tire 110 is "A degree". FIG. 12 (d) shows a case where the cutting angle of the tire 110 is “A °” and the steering wheel 10 faces in the straight traveling direction of the vehicle 100. Since the cutting angle of the tire 110 is “A °”, the assumed steering angle is “C °”. Further, since the steering angle of the steering wheel 10 is “0 °”, the relative steering angle is “C °”. Therefore, only the light emitting element 26 arranged at the portion corresponding to the relative steering angle “C °” is turned on.

  Under such circumstances, when the driver operates the mode switch 36 to input a switching instruction from the automatic steering mode to the manual steering mode for the vehicle 100, the mode switching switch 36 sends the switching instruction to the I / O unit. The I / O unit 42 outputs a switching instruction to the input unit 52. The input unit 52 outputs a switching instruction to the receiving unit 64 and the determining unit 54, and the receiving unit 64 instructs the display control unit 70 to display the switching mode.

  Even in the switching mode, the acquisition unit 80 and the generation unit 82 select one of the plurality of light emitting elements 26 forming the light emission band 24 by executing the same processing as before. On the other hand, in the switching mode, the display control unit 70 turns on the light emitting unit 22 via the I / O unit 42. In this way, the display control unit 70 is a light emitting unit 22 for turning on the portion corresponding to the relative steering angle in the light emitting band 24 and indicating the steering angle of the steering wheel 10, and is provided on the steering wheel 10. The light emitting unit 22 is turned on. Here, FIGS. 13A to 13D are used to describe the processing in the switching mode in detail.

  FIGS. 13A to 13D show another operation outline of the vehicle 100. In particular, FIG. 13A shows the direction of the tire 110 in the vehicle 100, that is, the cutting angle. Since this is the same as FIG. 12C, description thereof is omitted here. FIG. 13B shows the display in the case of FIG. Since the turning angle of the tire 110 and the steering angle of the steering wheel 10 are the same as in the case of FIG. 12B, the light emitting element 26 lit in FIG. 12B is also lit in FIG. 13B. Further, since the steering wheel 10 faces the direction in which the vehicle 100 goes straight, the steering angle indicated by the light-emitting unit 22 that is lit is “0 °”. In this situation, it can be said that the steering angle of the steering wheel 10 and the turning angle of the tire 110 do not correspond.

  FIG.13 (c) shows the cutting angle of the tire 110 in the condition following Fig.12 (a). Here, the cutting angle is assumed to be the same as FIG. 13A for the sake of clarity. FIG.13 (d) shows the display in the case of FIG.13 (c). The steering wheel 10 is inclined “C ° rightward” from the direction of the steering angle “0 °”. Therefore, the rudder angle indicated by the light emitting unit 22 that is lit is “C ° in the right direction”. Further, as described above, since the assumed steering angle is “C °”, the relative steering angle is “0 °”. Therefore, the light emitting element 26 arranged in the reference portion is turned on. In this way, the light emitting section 22 that is lit and the light emitting element 26 that is lit are aligned in the radial direction. Returning to FIG. Subsequent processes of the determination unit 54 and the switching control unit 56 are the same as those described above, and thus description thereof is omitted here.

  The operation of the vehicle 100 configured as above will be described. FIG. 14 is a flowchart showing a switching procedure by the vehicle 100. When the automatic steering mode is set (Y in S100), the acquisition unit 80 acquires information on the turning angle of the tire 110 (S102). The generation unit 82 calculates an assumed steering angle of the steering wheel 10 from information on the turning angle of the tire 110 (S104). The acquisition unit 80 acquires the current steering angle of the steering wheel 10 (S106). The display control unit 70 turns on the light emitting element 26 at a position representing the relative steering angle of the steering wheel 10 in red (S108). If the mode switch 36 is pressed down (Y in S110), the display control unit 70 turns on the light emitting unit 22 in red (S112).

  If the assumed steering angle of the steering wheel 10 matches the current movement of the steering wheel 10 (Y in S114), the determination unit 54 determines to switch from the automatic steering mode to the manual steering mode (S116). . When the assumed steering angle of the steering wheel 10 does not match the current movement of the steering wheel 10 (N in S114), the process returns to step 112. If it is not the automatic steering mode (N in S100), Step 102 to Step 116 are skipped. If the mode switch 36 is not depressed (N in S110), Step 112 to Step 116 are skipped.

  According to the present embodiment, since the steering angle pointer is also displayed in the same field of view of the light emitting element, the steering angle of the steering wheel according to the tire turning angle in the automatic steering mode can be notified. In addition, when the light-emitting element that is lit matches the light-emitting unit, switching from the automatic steering mode to the manual steering mode is determined, so that seamless switching can be realized. In addition, since the light emitting band and the light emitting unit provided on the steering wheel are turned on, other information can be displayed on the HUD.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to each of those constituent elements or combinations of processing processes, and such modifications are also within the scope of the present invention. .

And a display control unit for displaying an assumed steering angle of a steering wheel with respect to information on a tire turning angle acquired in the acquisition unit. The display control unit also displays the steering angle of the steering wheel within the same field of view of the assumed steering angle of the steering wheel.

  According to this aspect, since the steering angle of the steering wheel is also displayed within the same field of view of the steering wheel assumed steering angle, the steering angle of the steering wheel according to the tire turning angle in the automatic steering mode can be notified.

  The display control unit may display the steering angle of the steering wheel and the assumed steering angle of the steering wheel on one display unit. In this case, since the steering angle of the steering wheel and the assumed steering angle are displayed on one display unit, both can be easily confirmed.

  The display control unit may display the assumed steering angle of the steering wheel on the display unit, and may turn on a light emitting unit for indicating the steering angle of the steering wheel and provided on the steering wheel. In this case, the steering wheel may be rotated so as to match the display on the display unit, so that the operation by the driver can be facilitated.

  The display control unit lights up a portion corresponding to a difference between an assumed steering angle of the steering wheel and a steering angle of the steering wheel in the light emission band provided along the rim portion of the steering wheel, and the steering angle of the steering wheel. It is also possible to turn on a light emitting unit for indicating the light emitting unit provided on the steering wheel.

A determination unit that determines switching from the automatic steering mode to the manual steering mode for the vehicle when the assumed steering angle of the steering wheel displayed by the display control device matches the steering angle of the steering wheel; Also good. In this case, since the switching from the automatic steering mode to the manual steering mode is determined when the assumed steering angle and the steering angle coincide with each other, seamless switching can be realized.

  The display control device displays the assumed steering angle of the steering wheel when the switching instruction is not input to the input unit, and displays the assumed steering angle of the steering wheel and the steering angle of the steering wheel when the switching instruction is input to the input unit.
