The display device 100 will be described in detail later. In the present embodiment, although voice and display are shown as an example of the output device 10, information may be reported by vibration or light. Further, a plurality of voice, display, vibration, or light may be combined to report information.

The ECU29 controls the brake device 11 and a parking brake (not shown). The brake device 11 is, for example, a disc brake device, is provided to each wheel of the vehicle 1, and decelerates or stops the vehicle 1 by applying resistance to rotation of the wheel. The ECU29 controls the operation of the brake device 11 in accordance with, for example, the driver's driving operation (braking operation) detected by an operation detection sensor 7B provided on the brake pedal 7B. When the driving state of the vehicle 1 is the automatic driving, the ECU29 automatically controls the brake device 11 in response to an instruction from the ECU20 to decelerate and stop the vehicle 1. The brake device 11 and the parking brake can be operated to maintain the stopped state of the vehicle 1. In addition, even when the transmission of the power unit 6 has the parking lock function, the parking lock function can be operated to maintain the stopped state of the vehicle 1.

The ECU22 performs control of the detection means 50 that detects the rear side (left rear and right rear) of the vehicle 1 and information processing of the detection results. The detection means 50 is a camera (hereinafter, sometimes referred to as a camera 50) that takes an image of the rear side of the vehicle 1. In the present embodiment, the cameras 50 are provided one on each of the right and left sides of the vehicle 1. By analyzing the image captured by the camera 50, the contour of the target object on the left, right, rear side of the vehicle 1 can be extracted. Thus, the ECU22 can detect another vehicle on the left and right rear sides of the vehicle 1.

In the vehicle 1 configured as described above, an automatic driving function for automatically and autonomously driving the vehicle 1 can be realized. As a driving assistance technique for assisting the driving of the driver, it is possible to realize an Adaptive Cruise Control (ACC) for traveling along a preceding vehicle while maintaining an appropriate inter-vehicle distance between the host vehicle (vehicle 1) and the preceding vehicle, a collision reduction brake (CMBS) for performing assistance in stages for avoiding a collision or reducing injury with the preceding vehicle, a pedestrian, or an oncoming vehicle, and a Camera Monitoring System (CMS) for displaying an image showing the situation in place of a side mirror for allowing the driver to visually recognize the situation behind the vehicle. In the ACC, when the own vehicle approaches the preceding vehicle, the ECU20 automatically controls acceleration and deceleration of the own vehicle so that the own vehicle follows the preceding vehicle. In the CMBS, the detection units 41 to 43 detect the peripheral conditions of the vehicle 1 (hereinafter, sometimes referred to as vehicle peripheral conditions), and the ECU20 (in cooperation with the ECU22 and the ECU 23) detects objects (pedestrians (bicycles), preceding vehicles, oncoming vehicles, and the like) existing in the vehicle peripheral conditions detected by the detection units 41 to 43, and controls the traveling of the vehicle 1 (in cooperation with the ECU25 and the ECU 29) in accordance with the objects existing in the vehicle peripheral conditions. In the CMS, the ECU28 causes the monitor 130, described later, provided in the vehicle 1 to display an image indicating the rear side of the vehicle 1 obtained by the detection means 50.

Hereinafter, a vehicle body structure of the vehicle 1, particularly, the display device 100 mounted on the vehicle 1 in the present embodiment will be described with reference to fig. 2. Fig. 2 is a rear view of the vehicle 1 front compartment structure VFS. The vehicle cabin front structure VFS is provided with an instrument panel 60 for mounting various vehicle components. The instrument panel 60 is, for example, a resin-made panel, and may be constituted by a plurality of members or may be constituted by one member.

The display device 100 is mounted on the instrument panel 60, and has a function of displaying various information (images showing the information) to the occupant of the vehicle 1. In the present embodiment, as described above, the display device 100 is controlled by the ECU28 included in the controller 2 that controls the vehicle 1 (that is, the controller 2(ECU28) functions as a controller that controls the display device 100). However, a dedicated control unit for controlling the display device 100 may be provided separately from the control unit 2(ECU28) for controlling the vehicle 1. The display device 100 includes a display 110, an instrument panel 120, and a monitor 130 extending in the vehicle width direction (Y direction) and the up-down direction (Z direction) of the vehicle 1.

The instrument panel 120 is provided separately from the display 110 in the vehicle width direction, and is disposed adjacent to the display 110. The instrument panel 120 is a panel provided with various instruments such as a speedometer, a tachometer, a fuel gauge, a water thermometer, and a distance meter, or a panel for displaying measurement results thereof, and may be displayed in any of analog display and digital display. In the present embodiment, the dashboard 120 is disposed so as to overlap the steering wheel 31 in a rear view (rear view) in front of the driver's seat. The rear view corresponds to a viewpoint from the + X direction, but the same can be said for a front view (a viewpoint from the-X direction)).

The monitors 130 are provided at the left and right ends of the instrument panel 60, respectively. In order to realize the CMS, the monitor 130 displays an image showing the rear side of the vehicle 1 as described above. Thus, the driver can grasp the left rear side and the right rear side of the vehicle 1 without giving a sense of incongruity (confusion) by visually recognizing the left and right monitors 130 while performing a driving operation.

The steering wheel 31 is provided behind the instrument panel 60 and in front of the driver's seat. In the present embodiment, the driver seat is the seat on the right side of the front row of the vehicle 1, and the steering wheel 31 is provided on the right rear side of the instrument panel 60, but the present invention is not limited thereto, and the driver seat may be the seat on the left side of the front row of the vehicle 1, and the steering wheel 31 may be provided on the left rear side of the instrument panel 60.

The steering wheel 31 includes, for example, a coil 311, a hub 312, and a spoke 313. The coil 311 is provided in a ring shape so as to be held by the driver. The boss 312 is disposed inside the annular coil 311. The hub 312 is provided with, for example, a horn switch. The spoke portion 313 spans between the coil 311 and the hub portion 312. The spoke portion 313 is additionally provided with, for example, a push switch or the like. The boss 312 is connected to a steering shaft (not shown), and transmits a turning operation of the disk 311 by the driver to the steering shaft as a steering operation. In fig. 2, the center position of the outer shape of the coil 311 viewed from the rear (the position of the center between the upper end and the lower end and the center between the left side end and the right side end) is set as the center H0 of the steering wheel 31.

In the vehicle cabin front structure VFS, an adjustment mechanism 70 is provided at a position below the steering wheel 31. The adjustment mechanism 70 includes, for example, a tilt mechanism and a telescopic mechanism. The driver can adjust the position and posture of the steering wheel 31 using the adjustment mechanism 70.

Here, the display 110 will be described in detail. First, the structure of the display 110 will be described. Fig. 3 is a diagram showing an example of the structure of the display 110. The display 110 is provided on a side of the instrument panel 120 separately from the instrument panel 120. In the present embodiment, the display 110 is configured by a plurality of

panels

111 and 112 as shown in fig. 3, but may be configured by one panel. A touch panel display capable of inputting a touch operation is used as the display 110.

In the present embodiment, the display 110 includes a sub display region (first display region) 1110 and a main display region (second display region) 1120, the sub display region (first display region) 1110 includes a side edge 110a on the instrument panel 120 side, specifically, on the instrument panel 120 side, and the main display region (second display region) 1120 is adjacent to the sub display region 1110 on the side opposite to the instrument panel 120. The sub display area 1110 is a rectangular area having a first width Wd1 in the vehicle width direction (Y direction) of the vehicle 1 and a longitudinal direction in the up-down direction (Z direction) of the vehicle 1. The first width Wd1 is set, for example, in the range of 1cm to 5 cm. On the other hand, the main display region 1120 is a rectangular region having a second width Wd2 wider than the first width Wd in the vehicle width direction and having a longitudinal direction in the vehicle width direction. The second width Wd2 is set, for example, in the range of 75cm to 80 cm. Thus, as shown in fig. 3, the main display region 1120 has an area significantly larger than that of the sub display region 1110.

Next, information displayed on the display 110 will be described. In the present embodiment, map information related to the travel of the vehicle 1, or a moving image such as a television or movie is displayed in the main display region 1120 of the sub display region 1110 and the main display region 1120 constituting the display 110. However, in the vehicle 1, even when the shift position is the reverse position (R), an image indicating the rear of the vehicle 1 can be displayed in the second display region 1120. In this way, the ECU28 controls the display device 100 (the display 110) so that map information, a moving image, and the situation behind the vehicle 1 are displayed in the main display area 1120 of the display 110.

Further, information related to the automatic driving function is displayed in the sub display area 1110 of the sub display area 1110 and the main display area 1120 constituting the display 110. In the present embodiment, as shown in fig. 4A to 4D, information related to the automatic driving function is displayed in a partial region of the sub display region 1110, specifically, in an upper region 1110a of the sub display region 1110. In other words, the ECU28 controls the display device 100 (the display 110) so that information related to the automatic driving function is displayed in the upper region 1110a of the sub display region 1110 of the display 110.

Fig. 4A shows an example of the display of the sub display area 1110 in the case where the automatic driving function is OFF (OFF). As shown in fig. 4A, when the automatic driving function is in the off state, nothing is displayed in the upper region 1110a of the sub-display region 1110 in order to allow the driver to recognize that the automatic driving function is in the off state (not operating). However, the present invention is not limited to this, and "OFF" may be displayed in the upper area 1110a of the sub-display area 1110 as an identifier indicating that the automatic driving function is in the OFF state.

Fig. 4B shows an example of the display of the sub display area 1110 in the case where the automatic driving function is in the standby state. As shown in fig. 4B, in order to allow the driver to recognize that the automatic driving function is in the STANDBY state (operable) when the automatic driving function is in the STANDBY state, "STANDBY" is displayed in the upper area 1110a of the sub-display area 1110 as the identifier ID1 indicating that the automatic driving function is in the STANDBY state.

Fig. 4C shows an example of the display of the sub display area 1110 in the case where the automatic driving function is in the on state. As shown in fig. 4C, in order to allow the driver to recognize that the automated driving function is in the ON state (in operation) when the automated driving function is in the ON state, ON is displayed in the upper region 1110a of the sub display region 1110 as the identifier ID2 indicating that the automated driving function is in the ON state.

Fig. 4D shows an example of the display of the sub display area 1110 in the case where the automatic driving function is in the disabled state. As shown in fig. 4D, in order to make the driver recognize that the automatic driving function is in the INOPERABLE state when the automatic driving function is in the INOPERABLE state, an "INOPERABLE" is displayed as the identifier ID3 indicating that the automatic driving function is in the INOPERABLE state in the upper area 1110a of the sub-display area 1110.

By displaying the information relating to the automatic driving function in the sub display area 1110 of the display 110 in this manner, the driver can easily recognize (grasp) the state of the automatic driving function, that is, whether the automatic driving function is not operated, whether the automatic driving function is operable, whether the automatic driving function is operating, whether the automatic driving function is inoperable, or whether the automatic driving function is inoperable, as needed, without narrowing the display area of the dashboard 120. In order to further improve the driver's visibility of the state of the automatic driving function, "STANDBY", "ON", and "INOPERABLE" corresponding to the identifiers ID1, ID2, and ID3 indicating the state of the automatic driving function may be displayed in different colors, for example, "STANDBY" may be displayed in white, "ON" may be displayed in blue, and "INOPERABLE" may be displayed in red. At this time, the background color of the sub display region 1110 is black.

Further, in the sub display area 1110, information on the driving assistance functions (ACC, CMBS, and CMS in the present embodiment) provided by the vehicle 1 and information on the operation states of devices such as detection means and ECUs necessary for realizing the driving assistance functions are displayed. In the present embodiment, as shown in fig. 5, information relating to the driving assistance function provided by the vehicle 1 is displayed in the middle area 1110b that is a partial area of the sub display area 1110, and information relating to the operating state of the devices necessary to implement the driving assistance function is displayed in the lower area 1110c that is a partial area of the sub display area 1110. Here, the driving assistance function provided by the vehicle 1 is an example of the control state related to the traveling of the vehicle 1, and the control state related to the traveling of the vehicle 1 is not limited to the driving assistance function described above but includes other control states. Similarly, the operating state of the device is not limited to the operating state of the device necessary for realizing the above-described driving assistance function, but includes the operating state of the device necessary for causing the vehicle 1 to travel in various control states. For example, the operating states of the devices include operating states of operating devices (the electric power steering apparatus 3, the power unit 6, the brake apparatus 11, and the like) for operating the vehicle 1 in addition to the operating states of the

detection units

41, 42, 43, and 50, and the ECUs 20 to 29. In this way, ECU28 controls display device 100 (display 110) so that information relating to the driving assistance function provided by vehicle 1 and information relating to the operating state of the equipment necessary to implement the driving assistance function are displayed in middle region 1110b and lower region 1110c of sub display region 1110 of display 110. Fig. 5 shows an example of the display of the sub display area 1110 of the display 110, and in the present embodiment, shows a state in which all information that can be displayed in the middle area 1110b and the lower area 1110c is displayed.

As shown in fig. 5, in the present embodiment, "ACC", "CMBS", and "CMS" are displayed as identifiers ID11, ID12, and ID13 corresponding to ACC, CMBS, and CMS, respectively, in the middle area 1110b of the sub-display area 1110 in order for the driver to recognize the driving assistance function provided by the vehicle 1. In the present embodiment, as shown in fig. 5, icons IC1, IC2, and IC3 corresponding to the cameras 41, radar 43, and optical radar 42 required to realize "ACC" and "CMBS", respectively, and an icon IC4 corresponding to the camera 50 required to realize "CMS" are displayed in the lower region 1110c of the sub-display region 1110 as an example of devices (devices associated with driving assistance functions) required to realize the driving assistance function.

However, in the present embodiment, not all devices necessary for realizing the driving assistance function are displayed in the lower region 1110c of the sub-display region 1110, but only devices (detection means) that are inoperable due to the occurrence of an abnormality, and operable devices that are inoperable without the occurrence of an abnormality, as shown in fig. 6. In fig. 6, as devices which are disabled by occurrence of an abnormality, icons IC1 and IC3 corresponding to the camera 41 and the optical radar 42, respectively, are displayed in red, for example. In addition, in the middle area 1110b of the sub-display area 1110, the driving assistance function associated with the device that has become inoperable due to the occurrence of the abnormality (i.e., the driving assistance function that cannot be used) is displayed so as to be recognizable. In other words, in the intermediate area 1110b of the sub-display area 1110, depending on the operating states of devices such as detection means and ECUs necessary for realizing the driving assistance function, an unusable driving assistance function associated with a device that has an abnormality and cannot operate and an usable driving assistance function not associated with a device that has an abnormality and cannot operate (a driving assistance function associated with a device that has not an abnormality) are displayed so as to be distinguishable. For example, in the middle area 1110b of the sub-display area 1110, an identifier corresponding to a driving assistance function that can be used and an identifier corresponding to a driving assistance function that cannot be used are displayed in different colors. Specifically, in fig. 6, since the devices that are inoperable due to the occurrence of an abnormality are the camera 41 and the optical radar 42, the identifiers ID11 ("ACC") and ID12 ("CMBS") corresponding to the ACC and CMBS that are the driving assistance functions requiring the camera 41 and the optical radar 42 are displayed in red, and the identifier ID13 ("CMS") corresponding to the CMS that is the driving assistance functions not requiring the camera 41 and the optical radar 42 is displayed in white. The background color of the sub display region 1110 is black.

In this way, by displaying the information relating to the driving assistance function provided by the vehicle 1 and the information relating to the operating state of the equipment necessary to implement the driving assistance function in the sub display area 1110 of the display 110, the driver can easily recognize (grasp) the operating state of the equipment necessary to implement the driving assistance function and the driving assistance function provided by the vehicle 1 as needed without narrowing the display area of the dashboard 120.

Further, by displaying only the device in which the abnormality has occurred in the sub-display area 1110 of the display 110 and displaying the available driving assistance function and the unavailable driving assistance function in a recognizable manner, the driver can easily recognize (grasp), as needed, which of the available driving assistance functions (or unavailable driving assistance functions) is, which of the devices in which the abnormality has occurred, and the like.

In the present embodiment, since the device that has not generated an abnormality, that is, can operate is not displayed in the lower region 1110c of the sub-display region 1110, when there is no device that has generated an abnormality and cannot operate, nothing is displayed in the lower region 1110c of the sub-display region 1110 as shown in fig. 7. However, even in the above case, if there is a driving assistance function that cannot be used for some reason regardless of an abnormality of the device, the driving assistance function that can be used and the driving assistance function that cannot be used can be displayed in a distinguishable manner in the lower region 1110c of the sub-display region 1110.

In the case where a device that has become inoperable due to an abnormality is displayed in the lower region 1110c of the sub-display region 1110, the device may be displayed so that the position of the device in the vehicle 1 is clear. In other words, the position of the device in the vehicle 1 where the abnormality has occurred may be displayed in a recognizable manner in the lower region 1110c of the sub-display region 1110. For example, as shown in fig. 8, icons corresponding to devices that have become inoperable due to an abnormality displayed in the lower region 1110c of the sub-display region 1110 are divided into four regions corresponding to the front right, front left, rear right, and rear left of the vehicle 1, and the region corresponding to the position of the device in the vehicle 1 among the four regions is displayed so as to be distinguishable from the other regions. Fig. 8 shows an icon IC3 displayed in a lower region 1110c of the sub-display region 1110 in the case where an abnormality occurs in the optical radar 42 on the right front side among the four optical radars 42 mounted on the right front side, the left front side, the right rear side, and the left rear side of the vehicle 1. In fig. 8, the upper right area of the icon IC3 corresponding to the front right of the vehicle 1 is displayed in a different color from the other areas. For example, the upper right area of the icon IC3 is displayed in red, and the other areas are displayed in white. This enables the driver to easily recognize (grasp), as needed, the position of the device in the vehicle 1 in which the abnormality has occurred.

Further, it is preferable that the first width Wd1 of the sub-display area 1110 of the display 110 is variable. For example, when the driver (passenger) instructs to use the automatic driving function and the driving assistance function provided by the vehicle 1, the automatic driving function and the driving assistance function instructed by the driver may not be used. In this case, the first width Wd1 of the sub display area 1110 is enlarged and the information on the automatic driving function and the information on the driving assistance function displayed in the sub display area 1110 are enlarged and displayed. This makes it possible for the driver to easily recognize (grasp) that the automatic driving function or the driving assistance function provided by the vehicle 1 cannot be used.

In addition, regardless of whether the automatic driving function or the driving assistance function can be used, the first width Wd1 of the sub-display area 1110 may be reduced as long as the use of the automatic driving function or the driving assistance function is not instructed by the driver (passenger), and the first width Wd1 of the sub-display area 1110 may be enlarged as long as the use of the automatic driving function or the driving assistance function is instructed by the driver (passenger). However, when the automatic driving function and the driving assistance function cannot be used, the first width Wd1 of the sub display area 1110 may be enlarged from the viewpoint of improving visibility even if the use of the automatic driving function and the driving assistance function is not instructed by the driver. In this case, the instrument panel 120 may further display a message indicating that the automatic driving function or the driving assistance function cannot be used.

Next, the positional relationship between the display 110 and the steering wheel 31 will be described. As shown in fig. 9, the display 110 is arranged such that at least a part of the lower side of the sub display area 1110, specifically, the middle area 1110b and the lower area 1110c overlap a part of the steering wheel 31 (the wheel rim 311) in the line of sight of the driver.

The line of sight of the driver is defined, for example, by a regulation such as the regulation (UN/ECE-R46) specified by the european economic commission of the united nations.

Here, the driver's sight line is defined based on:

https：//www.unece.org/trans/main/wp29/wp29wgs/wp29gen/gen2015.html

"The driver's ocular points (position of driver's eyes)" described in section II 12 of ECE/TRANS/WP.29/2015/84.

As shown in fig. 2, a line passing through the center H0 of the steering wheel 31 and parallel to the vehicle width direction (Y direction) of the vehicle 1 is located closer to the lower end H2 side of the display 110 than a line passing through the center H23 between the upper end H3 of the display 110 and the lower end H2 of the display 110 and parallel to the vehicle width direction. As described above, although the position and the posture of the steering wheel 31 are adjusted by the adjustment mechanism 70, the positional relationship between the display 110 and the steering wheel 31 shown in fig. 2 is maintained within the adjustment range of the position and the posture of the steering wheel 31 by the adjustment mechanism 70.

In the positional relationship between the display 110 and the steering wheel 31 as described above, information on the automatic driving function and the driving assistance function provided by the vehicle 1 is displayed above the sub-display area 1110, for example, in the upper area 1110a and the middle area 1110b, and information on the operation state of the devices necessary for realizing the driving assistance function is displayed below the sub-display area 1110, for example, in the lower area 1110 c. As described above, the information on the operation state of the equipment estimated to have a low influence on the driver (occupant) is displayed below the sub display area 1110 having a high possibility of overlapping the steering wheel 31 (the rim 311), and the information on the automatic driving function and the driving assistance function directly related to the traveling of the vehicle 1 (that is, estimated to have a high influence on the driver) is displayed above the sub display area 1110 having a low possibility of overlapping the steering wheel 31, whereby the driver can reliably recognize (grasp) the information having a relatively high importance in the traveling of the vehicle 1.

Further, as described above, since the display 110 is formed by a touch panel display, it is generally easy to recognize that information displayed on the display 110 is selectable. On the other hand, in the present embodiment, the information related to the automatic driving function, the information related to the driving assistance function, and the information related to the operation state of the device necessary for realizing the driving assistance function, which are displayed in the sub display area 1110 of the display 110, do not necessarily have to be selectable. Therefore, by displaying the information as described above in the sub display area 1110 on the instrument panel 120 side of the display 110, it is possible to effectively use an area that is highly likely to overlap the steering wheel 31 (the rim 311), that is, an area that is difficult for the driver to operate (an area that is difficult for the driver to reach).

In addition, as shown in fig. 10, the display 110 may be configured such that the sub display region 1110 is parallel to the vehicle width direction (Y direction) and the main display region 1120 has an angle with respect to the vehicle width direction, from a viewpoint in the up-down direction (Z direction) of the vehicle 1. This makes it possible to arrange the display 110 so that the driver can easily see the sub display region 1110 and so that the passengers other than the driver can easily see the main display region 1120, and the degree of freedom in the arrangement of the display 110 can be improved.

In addition, the automatic driving function and the driving assistance function may be realized even if an abnormality occurs in a part of the devices necessary for realizing them. In such a case, the above-described functions may be displayed as usable functions. However, it is preferable that the display is displayed separately from the functions that can be used in association with the device in which no abnormality has occurred, and for example, the identifier corresponding to the function that can be used even if an abnormality has occurred in a part of the device is represented in yellow instead of white.

The information on the automatic driving function and the information on the driving assistance function may be displayed in the order of the number of devices necessary for realizing them, or may be displayed in the order of the functions of high rank (necessity) from the viewpoint of automatic driving and driving assistance. For example, in view of automatic driving and driving assistance, when it is considered that the ACC and CMBS are ranked higher than the CMS, the ACC and CMBS are displayed at a position above the CMS.

As described above, according to the present embodiment, it is possible to provide a new technique for improving usability for a vehicle, particularly for a display device mounted on the vehicle.
