Display method and display system

[0001] The present invention relates to a display method and a display system.

[0002] Patent Document 1 discloses a vehicle in which the driver can grasp the direction of the wheels. When the wheels are automatically steered and the steering wheel is fixed, a display unit displays the direction of the wheels that are automatically steered.

[0003] Japanese Patent Application Laid-Open No. 2021-102372

[0004] In this type of vehicle, the driving mode can be switched between an autonomous driving mode, in which the wheels are steered automatically, and a non-autonomous driving mode. However, in conventional methods, the difference between the driving modes is not sufficiently taken into consideration when displaying information.

[0005] An object of the present invention is to provide a display method and a display system that can display information that reflects differences in driving modes.

[0006] A display method according to one aspect of the present invention displays information corresponding to the wheel steering angle on a display when the vehicle's driving mode is an autonomous driving mode, and does not display information corresponding to the wheel steering angle on a display when the vehicle's driving mode is not an autonomous driving mode.

[0007] According to one aspect of the present invention, it is possible to display appropriate information depending on the driving mode of the vehicle.

FIG. 8 is a diagram illustrating an example of steering information. FIG. 9 is a diagram illustrating information displayed on a rotating steering wheel.

[0009] (First embodiment) A steering wheel 1 mounted on a vehicle will be described with reference to Fig. 1 . The steering wheel 1 is provided in the driver's seat of the vehicle and is arranged to face the seat on which the driver sits. The steering wheel 1 is configured to be rotatable about a rotation axis 1a. The steering wheel 1 is an operator for steering the vehicle and is held by the driver. The steering operation by the driver is received by the steering wheel 1.

[0010] The steering wheel 1 includes a wheel body 2, a boss portion 3, and a steering display 20.

[0011] The wheel body 2 is an annular member that is gripped by the driver. The wheel body 2 is arranged concentrically around the rotation axis 1a. The boss portion 3 is connected to the steering shaft 6. An airbag module is attached to the boss portion 3. The boss portion 3 also functions as a horn switch that the driver presses to sound the horn.

[0012] The driver performs a steering operation by rotating the steering wheel 1. The steering operation performed by the driver is reflected in the wheels W via the steering device 4. The steering device 4 is of a steer-by-wire type in which a steering mechanism 5 including the steering wheel 1 and a steering mechanism 8 that steers the wheels W are mechanically separated. The steering device 4 generates a control signal corresponding to the rotation angle (steering angle) of the steering wheel 1 operated by the driver, and controls the steering mechanism 8 based on the control signal.

[0013] The steering mechanism 5 includes a steering wheel 1, a steering shaft 6, and a steering actuator 7. The steering shaft 6 is arranged so that its central axis coincides with the rotation axis 1a, and the steering wheel 1 is connected to the tip of the steering shaft 6. The steering actuator 7 is connected to the steering shaft 6. The steering actuator 7 applies a steering reaction force when the driver steers the steering wheel 1, and prevents the steering wheel 1 from rotating in an autonomous driving mode. The steering mechanism 8 includes a steering actuator 9, and the direction (steering angle) of the wheels W is changed by driving the steering actuator 9. The steering device 4 includes a controller (not shown) that generates control signals and controls the steering mechanism 5 and the steering mechanism 8.

[0014] The steering display 20 is a display device that displays information necessary for driving. The steering display 20 has an annular shape and is arranged concentrically around the rotation axis 1a. The steering display 20 is arranged in a range inside the steering wheel 1 and outside the boss portion 3. The steering display 20 is integrated with the wheel body 2 and the boss portion 3, and the wheel body 2, steering display 20, and boss portion 3 rotate together.

[0015] The steering display 20 is a transparent display that transmits external light while displaying information. An instrument panel is provided behind the steering wheel 1 as seen from the driver, and an instrument unit 100 is provided on the instrument panel. The instrument unit 100 includes instruments such as a speedometer, a tachometer, and a fuel gauge, as well as various warning lights. The driver can view the instrument unit 100 behind the steering wheel 1 through the transparent steering display 20. Note that the instrument unit 100 is depicted in a simplified form in FIG. 1 .

[0016] The steering display 20 is a touch panel display equipped with a touch panel through which the user inputs operation instructions. The touch panel detects a touch position on the steering display 20. The touch panel is, for example, of a capacitance type, but is not limited to this and may be of another type such as a resistive film type.

[0017] The vehicle according to this embodiment has two driving modes: an autonomous driving mode and a non-autonomous driving mode.

[0018] The autonomous driving mode is a mode in which a plurality of vehicle controls are automatically executed to assist the driver in driving. For example, in the autonomous driving mode, steering control, braking force control, and driving force control are automatically executed, so that the steering of the wheels W, the accelerator operation, and the brake operation are automatically performed.

[0019] Here, the autonomous driving mode includes a hands-on mode in which the driver must hold the steering wheel 1, and a hands-off mode in which the driver can release his or her hands from the steering wheel 1 by satisfying certain conditions. In this embodiment, the autonomous driving mode will be described assuming the hands-off mode. When the autonomous driving mode is selected, the steering device 4 prevents the steering wheel 1 from rotating. In other words, the steering wheel 1 is maintained in a neutral state regardless of the steering angle of the wheels W due to steering control.

[0020] The non-autonomous driving mode is a mode in which the driver manually drives the vehicle. In this non-autonomous driving mode, all vehicle operations, including steering, acceleration, and braking, are performed by the driver himself. In the non-autonomous driving mode, the steering device 4 calculates the steering angle of the wheels W by multiplying the steering angle of the steering wheel 1 by a predetermined steering gear ratio. The steering device 4 then controls the steering actuator 9 based on a control signal corresponding to the calculated steering angle, thereby controlling the direction (steering angle) of the wheels W.

[0021] Although steering control, braking force control, and driving force control have been exemplified as the autonomous driving modes, the autonomous driving mode according to this embodiment may be any mode that does not require at least steering operation by the driver. Similarly, the non-autonomous driving mode may be any mode that requires at least steering operation by the driver.

[0022] The display system 10 according to this embodiment is composed of the above-described steering display 20 and a controller 50. The display system 10 also includes a center display 30 that is different from the steering display 20. The center display 30 is disposed in a position visible to the driver, for example, in the center of the instrument panel.

[0023] The controller 50 is configured by a computer having a hardware processor such as a CPU (Central Processing Unit), memory, and various interfaces. The CPU reads various computer programs stored in the memory and executes various instructions contained in the programs. By executing the programs, the CPU functions as various information processing circuits. The controller 50 realizes the functions of each information processing circuit using software, but it is also possible to realize those functions using dedicated hardware.

[0024] Various types of information are input to the controller 50. The touch signal St is a signal that indicates a touch position on the steering display 20. The touch signal St is output from the touch panel of the steering display 20.

[0025] The steering angle signal Sθ is a signal that indicates the steering angle of the steering wheel 1. The steering angle signal Sθ is output from a sensor that detects the rotation angle of the steering shaft 6.

[0026] The operation mode signal Sp is a signal that indicates whether the operation mode is the automatic operation mode or not, and is output from a host controller that controls the automatic operation function.

[0027] In this embodiment, the controller 50 controls the information displayed on the steering display 20. The information displayed on the steering display 20 will be described with reference to Figure 2. In Figure 2, a reference line 2a shown by a dashed line on the wheel body 2 indicates a reference position on the wheel body 2. The reference line 2a is located directly above the steering wheel 1 when it is in the neutral position (the position shown in Figure 2). Similarly, a reference line 3a shown by a dashed line on the boss portion 3 indicates a reference position on the boss portion 3. The reference line 3a is aligned in the up-down direction when the steering wheel 1 is in the neutral position (the position shown in Figure 2). That is, Figure 2 shows how information is displayed when the steering wheel 1 is in the neutral position.

[0028] The controller 50 displays the operation information Ic, the notification information Ii, and the steering information Ij on the steering display 20.

[0029] The operation information Ic includes one or more pieces of information for the driver to operate the devices installed in the vehicle. In the example shown in Fig. 2, the operation information Ic includes first operation information Ica, second operation information Icb, third operation information Icc, fourth operation information Icd, and fifth operation information Ice.

[0030] The first operation information Ica is information for operating the volume of a speaker installed in a vehicle. The first operation information Ica includes a symbol, character, or icon indicating an operation to increase the volume, and a symbol, character, or icon indicating an operation to decrease the volume. The second operation information Icb is information for performing an operation to return to the previous screen. The second operation information Icb includes a symbol, character, or icon indicating an operation to return to the previous screen. The third operation information Icc is information for performing an operation to answer an incoming call and an operation to end a call.

[0031] The fourth operation information Icd is information for operating the set vehicle speed in the driving assistance function. The fourth operation information Icd includes symbols, letters, or icons indicating operations for setting or lowering the set vehicle speed. The fourth operation information Icd also includes symbols, letters, or icons indicating operations for resetting the set vehicle speed to the speed before the constant speed control function was released after the constant speed control function was released. The fifth operation information Ice is information for turning the driving assistance function on and off. The fifth operation information Ice includes symbols, letters, or icons indicating the driving assistance function.

[0032] The driver can perform a necessary operation by touching the operation information Ic, specifically, any of the first to fifth operation information Ica, Icb, Icc, Icd, and Ice.

[0033] The notification information Ii includes one or more pieces of information to notify the driver. In the example shown in Fig. 2, the notification information Ii includes information to notify the driver of the details of the autonomous driving mode. Specifically, the notification information Ii includes an icon indicating that the driver can release his / her hands from the steering wheel 1, an icon indicating whether a preceding vehicle has been detected, and text indicating the set speed during autonomous driving.

[0034] The steering information Ij is information corresponding to the steering angle of the wheels W. Details of the steering information Ij will be described later.

[0035] The operation information Ic displayed on the steering display 20 is not limited to the above information, but may include information for operating various devices mounted on the vehicle. The notification information Ii is not limited to the above information, but may include other information related to the driving assistance function. The notification information Ii may include information notifying information related to the vehicle other than the driving assistance function. Furthermore, the contents of the operation information Ic, notification information Ii, and steering information Ij are dynamically changed depending on the state of the vehicle and the driving situation.

[0036] A display method according to this embodiment, specifically, a method for controlling information displayed on the steering display 20, will be described with reference to Fig. 3. The flowchart shown in Fig. 3 is periodically executed by the controller 50.

[0037] The controller 50 refers to the driving mode signal Sp and determines whether the driving mode is the autonomous driving mode (S10). As shown in Fig. 4, if the driving mode is not the autonomous driving mode (S10: NO), the controller 50 does not display the steering information Ij on the steering display 20 (S11). In this case, the controller 50 can display information other than the steering information Ij on the steering display 20. In the example shown in Fig. 4, the first to fifth operation information Ica, Icb, Icc, Icd, and Ice are displayed on the steering display 20.

[0038] Here, assume that the driver swipes any of the first to fifth operation information Ica, Icb, Icc, Icd, and Ice, for example, the fifth operation information Ice (see FIG. 5 ). The controller 50 hides the swiped fifth operation information Ice on the steering display 20 and instead displays the swiped fifth operation information Ice on the center display 30. In this way, the information displayed on the steering display 20 and the center display 30 can be switched by the driver's swipe operation.

[0039] On the other hand, if the driving mode is the automatic driving mode (S10: YES), the controller 50 displays the steering information Ij on the steering display 20 (S12), as shown in Fig. 6. The steering information Ij will be described below.

[0040] The steering information Ij is information corresponding to the steering angle of the wheel W. As described above, when the driving mode is the autonomous driving mode, the steering wheel 1 is maintained in a neutral position. Therefore, even when the wheel W is being steered, the driver cannot grasp the extent to which the wheel W is being steered. The steering information Ij functions as information that allows the driver to recognize the steering angle of the wheel W. However, the driver of a vehicle does not recognize the steering angle of the wheel W directly, but rather recognizes the steering angle of the wheel W primarily through the steering angle of the steering wheel 1. Therefore, in this embodiment, information corresponding to the steering angle of the steering wheel 1 is displayed as the steering information Ij. The controller 50 can identify the steering angle of the steering wheel 1 by multiplying the steering angle of the wheel W by a predetermined coefficient (the reciprocal of the steering gear ratio) by the steering control. Because the steering angle of the steering wheel 1 is proportional to the steering angle of the wheel W, the driver can grasp the steering angle of the wheel W through the steering angle of the steering wheel 1.

[0041] In this embodiment, the steering information Ij is configured as an arc-shaped gauge displayed on the inside of the wheel body 2 in an arc shape that follows the circular shape of the wheel body 2. This arc-shaped gauge is displayed on the right or left side of the center of the steering wheel 1 depending on the steering direction of the steering wheel 1. For example, when the steering direction of the steering wheel 1 is leftward (counterclockwise), the arc-shaped gauge is displayed on the left side, as shown in FIG.

[0042] The arc-shaped gauge extends in an arc shape with its base end located directly above the center of the steering wheel 1. The arc-shaped gauge is displayed so that the angle from the base end to the tip end of the arc-shaped gauge as viewed from the center of the steering wheel 1 is the same as the steering angle of the steering wheel 1. However, the angle of the arc-shaped gauge does not need to exactly match the steering angle of the steering wheel 1, and may be an angle obtained by multiplying the steering angle of the steering wheel 1 by a certain coefficient. This makes it possible to exaggerate or understate the steering angle of the steering wheel 1. The angle of the arc-shaped gauge may also be the steering angle of the wheels W itself.

[0043] In the example shown in FIG. 6 , the arc-shaped gauge is displayed with a gradation in which the color becomes darker from the base end to the tip as the steering angle increases. The arc-shaped gauge may be displayed with a gradation in which the hue changes from the base end to the tip as the steering angle increases, or may be displayed with the same density and hue from the base end to the tip. As shown in FIG. 7 , the controller 50 may display only the tip (line) of the arc-shaped gauge. Furthermore, as shown in FIG. 8 , when the entire inside of the wheel body 2 is made up of the steering display 20, the controller 50 may display the steering information Ij in the center of the steering wheel 1. In this case, the controller 50 rotates the steering information Ij in accordance with the steering angle of the steering wheel 1.

[0044] When the driving mode is the autonomous driving mode, the controller 50 may display information other than the steering information Ij. In the example shown in Fig. 6, the controller 50 displays the notification information Ii in addition to the steering information Ij. The notification information Ii is as described above.

[0045] Furthermore, when the driving mode is the autonomous driving mode, the controller 50 displays the operation information Ic on the center display 30. That is, the controller 50 displays on the center display 30 the information that is displayed on the steering display 20 when the driving mode of the vehicle is not the autonomous driving mode.

[0046] In this way, the display method according to this embodiment displays information (steering information Ij) corresponding to the steering angle of the wheels W on the steering display 20 when the driving mode is the autonomous driving mode, and does not display information corresponding to the steering angle of the wheels W on the steering display when the driving mode is not the autonomous driving mode. When the driving mode of the vehicle is the autonomous driving mode, the steering device 4 prevents the steering wheel 1 from rotating.

[0047] When the driving mode is the autonomous driving mode, the steering wheel 1 does not rotate. By displaying information according to the steering angle of the wheels W, the driver can be made aware of the state of the steering angle of the wheels W. On the other hand, when the driving mode is not the autonomous driving mode, the driver operates the steering wheel 1, so the driver can be aware of the steering angle of the steering wheel 1, i.e., the steering angle of the wheels W. Therefore, the information according to the steering angle of the wheels W can be hidden. In this way, the display method according to this embodiment can display information that reflects the difference in driving mode.

[0048] In the display method according to this embodiment, displaying information according to the steering angle of the wheels W includes displaying information according to the rotation angle (steering angle) of the steering wheel 1 required for the steering angle. A driver who drives a vehicle does not directly recognize the steering angle of the wheels W, but tends to recognize the steering angle of the wheels W through the steering angle of the steering wheel 1. Therefore, if the steering angle of the wheels W is displayed directly, it may be difficult to grasp the turning radius of the vehicle and the speed at which the wheels W turn. In this regard, according to this embodiment, information according to the rotation angle of the steering wheel 1 is displayed, so that the turning radius and the speed at which the wheels W turn can be appropriately grasped.

[0049] In the display method according to this embodiment, the steering display 20 is provided on the steering wheel 1 that receives steering operations by the driver. According to this method, information is displayed on the steering wheel 1 that is used to steer the vehicle (steer the wheels W). This allows the state of the steering angle of the wheels W to be understood in association with the steering wheel 1, which is the operator. Note that in this embodiment, information according to the steering angle of the wheels W is displayed on the steering display 20, but it may also be displayed on the center display 30 or another display. Also, in this embodiment, the steering wheel 1 is exemplified as an operator that receives steering operations by the driver, but this is not limiting. The operator may be a shape other than a ring shape, or may be a lever type.

[0050] In the display method according to this embodiment, the vehicle further includes a center display 30 (an example of a second display) that is visible to the driver, in addition to the steering display 20. When the vehicle's driving mode is the autonomous driving mode, the operation information Ic that is displayed on the steering display 20 when the vehicle's driving mode is not the autonomous driving mode is displayed on the center display 30. This method makes it possible to display information that reflects the difference between driving modes.

[0051] In the display method according to this embodiment, the driver's swipe operation switches between the information displayed on the steering display 20 and the information displayed on the center display 30. According to this method, the information displayed on the steering display 20 and the information displayed on the center display 30 can be switched with a simple operation.

[0052] Second Embodiment The display system 10 and the display method according to the second embodiment differ from the display system 10 and the display method according to the first embodiment in the state of the steering wheel 1 in the autonomous driving mode. In the first embodiment, in the autonomous driving mode, the steering wheel 1 remains in a neutral state regardless of the steering angle of the wheels W due to steering control. In contrast, in the second embodiment, in the autonomous driving mode, the steering device 4 rotates the steering wheel 1 in accordance with the steering angle of the wheels W.

[0053] Fig. 9 shows a state in which, in the autonomous driving mode, the steering wheel 1 is rotated in accordance with the steering angle of the wheels W. Specifically, the steering device 4 calculates the steering angle of the steering wheel 1 by multiplying the steering angle of the wheels W by a predetermined coefficient (the reciprocal of the steering gear ratio) by steering control. The steering device 4 controls the direction (steering angle) of the steering wheel 1 by controlling the steering actuator 7 in accordance with the calculated steering angle. The example shown in Fig. 9 shows a state in which the steering wheel 1 is rotated 60° counterclockwise.

[0054] In the second embodiment, the controller 50 also displays the steering information Ij on the steering display 20. In the example shown in Fig. 8, the angle from the base end to the tip end of the arc-shaped gauge is also displayed as 60° in accordance with the steering angle of the steering wheel 1.

[0055] When the steering wheel 1 rotates, the steering display 20 also rotates in conjunction with the rotation of the steering wheel 1. At this time, if the information also rotates in conjunction with the steering display 20, it will be difficult for the driver to see. Therefore, the controller 50 controls the information displayed on the steering display 20 so that the information does not rotate relative to the driver (vehicle body) regardless of the steering angle of the steering wheel 1. That is, the controller 50 displays the information in a fixed coordinate system in which the coordinate system is fixed regardless of the steering angle of the steering wheel 1. Specifically, the controller 50 controls the display information to rotate around the rotation axis 1a of the steering wheel 1 by the same angle as the steering angle, in the opposite direction to the steering angle of the steering wheel 1. The information displayed on the steering display 20 is displayed so as not to rotate with the rotation of the steering wheel 1. That is, the information displayed on the steering display 20 is displayed in the same position and orientation (unmoving state) even when the steering wheel 1 is rotated.

[0056] Unlike the first embodiment, FIG. 9 shows an example in which operation information Ic is displayed on the steering display 20. The operation information Ic is operated by the driver by touch. If the rotation speed of the steering wheel 1 is fast, there is a risk that the driver's fingers may be dragged or flicked off the rotating steering display 20. Therefore, the controller 50 may switch whether or not to display the operation information Ic depending on the rotation speed of the steering wheel 1. Specifically, the controller 50 displays the operation information Ic on the steering display 20 when the rotation speed of the steering wheel 1 is equal to or less than a predetermined threshold. On the other hand, the controller 50 does not display the operation information Ic on the steering display 20 when the rotation speed of the steering display 20 is greater than the threshold.

[0057] As described above, according to the display method of this embodiment, the steering wheel 1 rotates in accordance with the steering angle of the wheels W. In hands-off mode, the driver can take his or her hands off the steering wheel 1, so even if the steering wheel 1 is rotating, it may be difficult to grasp how much it has rotated from the neutral position. Therefore, by displaying information in accordance with the steering angle of the wheels W, the driver can be made aware of the state of the steering angle of the wheels W. On the other hand, when the autonomous driving mode is not in automatic driving mode, the driver himself or herself operates the steering wheel 1, so it is possible to hide information in accordance with the steering angle of the wheels W. As described above, according to the display method of this embodiment, it is possible to display information that reflects differences in driving modes.

[0058] Furthermore, the information displayed on the steering display 20 is displayed so as not to rotate in accordance with the rotation of the steering wheel 1. According to this method, even in a situation where the steering wheel 1 rotates in accordance with the steering angle of the wheels W, the information displayed on the steering display 20 is displayed in the same position and orientation. This makes it possible to display information in a form that is easy for the user to see.

[0059] In the display method according to this embodiment, when the rotation speed of the steering wheel 1 is equal to or less than a threshold, the operation information Ic is displayed on the steering display 20, and when the rotation speed of the steering wheel 1 is greater than the threshold, the operation information Ic is not displayed on the steering display 20. According to this method, when the rotation speed of the steering wheel 1 is high, the driver will not touch the operation information Ic. This can prevent the occurrence of situations where the driver's fingers are dragged or flicked by the rotating steering display 20.

[0060] As described above, the present embodiment also includes a display system 10 including a display (e.g., steering wheel display 20) visible to the vehicle driver and a controller 50 that controls the information displayed on the display. The controller 50 performs the above-described display method. This display system can display information that reflects different driving modes.

[0061] Although the embodiments of the present invention have been described, the descriptions and drawings that form part of this disclosure should not be understood as limiting the present invention. From this disclosure, various alternative embodiments, examples, and operating techniques will become apparent to those skilled in the art.
