Description

This disclosure relates to a display system for vehicles, etc.

Conventionally, some vehicles equipped with an adaptive cruise control (ACC) function display the ACC settings, such as the vehicle's speed and the distance to the vehicle ahead, on a display device such as a meter display or a head-up display, in response to input operations by a user such as the driver.

JP 2017-041126 A

These settings may be entered while the vehicle is traveling, and as a result, the display device is required to convey setting information to the driver with even better visibility.

This disclosure has been made in consideration of these circumstances, and aims to provide a display system with excellent information transmission capabilities.

The display system 10 of the present disclosure includes a display unit 8, 9 that displays a setting image 99 that allows a user 4 to visually confirm a setting value of the vehicle 1, and a control unit 40 that receives the setting value from the user 4 and controls the state of the setting image 99 displayed on the display units 8, 9. The setting image 99 has a first image E1 that appears when viewed from a first line of sight 4a where the user 4 looks forward from the vehicle 1, and a second image E2 that appears when viewed from a second line of sight that is different from the position of the first line of sight. The control unit 40 switches the setting image 99 from the first image E1 to the second image E2 when changing the setting value.

An embodiment of the display system of the present disclosure will be described with reference to the attached drawings. The display system of the present disclosure can be applied to display systems mounted on vehicles such as automobiles and motorcycles, ships, agricultural machinery, and construction machinery. In this embodiment, the display system of the present disclosure will be described using an example in which the display system is mounted on a vehicle and has two head-up displays (HUDs) that display required information based on various information acquired from the vehicle.

In the following description, "front," "rear," "up," "down," "right," and "left" follow the definitions in the figure of "Fr.", "Re.", "To.", "Bo.", "R," and "L." Note that "front" refers to the direction in which the driver (user) 4 in the driver's seat is facing (the traveling direction of the vehicle 1).

First Embodiment
The display system 10 is mounted in an instrument panel 2 of a host vehicle 1. The display system 10 has an upper HUD (first display) 20, a lower HUD (second display) 30, and a main control unit (control unit) 40.

The upper HUD 20 is disposed forward of the steering wheel 5, and irradiates display light L1 onto a transparent portion formed on the windshield 3 in front of the driver 4 of the vehicle 1. The reflected display light L1 is reflected by the windshield 3 toward the driver 4, allowing the driver 4 to view an image formed by a virtual image (first virtual image) V1 in front of the windshield 3. The image displayed by the upper HUD 20 is displayed, for example, within the virtual upper HUD display area (first display portion) 8 in FIG. 2, and is viewed superimposed on the scenery ahead, such as the road surface.

The lower HUD 30 is disposed further forward (away from the driver 4) than the upper HUD 20, and irradiates the display light L2 to the light-shielding portion 3a formed on the outer periphery of the transparent portion of the windshield 3. The light-shielding portion 3a is a portion made of a light-shielding color such as black, made of black ceramics or the like. The light-shielding portion 3a is formed for the purpose of preventing deterioration of the adhesive that fixes the windshield 3 to the vehicle 1 due to sunlight, concealing the adhesive, and improving the design. The reflected display light L2 is reflected by the light-shielding portion 3a toward the driver 4, thereby allowing the driver 4 to view an image formed by a virtual image (second virtual image) V2 in front of the windshield 3. The image displayed by the lower HUD 30 is displayed, for example, in a virtual lower HUD display area (second display portion) 9 different from the upper HUD display area 8 in FIG. 2, and is viewed forward of the light-shielding portion 3a.

The upper HUD 20 displays an image such that the image created by the virtual image V1 is visible at a distance (first display distance) d1 in the vertical direction relative to the line of sight 4a of the driver 4 expected in normal driving conditions. The lower HUD 30 displays an image such that the image created by the virtual image V2 is visible at a distance (second display distance) d2 that is greater than the distance d1 relative to the line of sight 4a of the driver 4.

That is, the driver 4 must move a greater distance to shift his/her line of sight 4a to the image related to the display light L2 than the distance he/she must move to shift his/her line of sight 4a to the image related to the display light L1. In other words, the angle θ2 formed by the direction of the line of sight 4a and the line of sight for viewing the image based on the virtual image V2 is greater than the angle θ1 formed by the direction of the line of sight 4a and the line of sight for viewing the image based on the virtual image V1. Therefore, the driver 4 views the image displayed by the lower HUD 30 at a position farther from the line of sight 4a than the image displayed by the upper HUD 20, below the image displayed by the upper HUD 20.

In addition, in this embodiment, the upper HUD 20 forms a virtual image V1 in front of the virtual image V2 formed by the lower HUD 30. That is, the image formed by the virtual image V1 is viewed from a position farther from the driver 4 in the fore-and-aft direction, and the image formed by the virtual image V2 is viewed from a position closer to the driver 4 in the fore-and-aft direction.

The display surface as the upper HUD display area 8 and the lower HUD display area 9 is a surface having four sides, top, bottom, left and right. For example, the bottom sides 8a, 9a and the top sides 8b, 9b are sides that are approximately parallel to the left-right direction. The left sides 8c, 9c and the right sides 8d, 9d are surfaces that are set at any angle to the up-down direction. For example, the display surface is formed so that the left sides 8c, 9c and the right sides 8d, 9d are surfaces that run along the up-down direction (surface perpendicular to the road surface), inclined at a predetermined angle to the up-down direction (surface inclined to the road surface), or surfaces that run along the front-rear direction (surface that is superimposed (approximately parallel) to the road surface).

The display surface may also be a surface formed such that the left sides 8c, 9c and right sides 8d, 9d are curved in a vertical direction on the side closer to the viewer and in a longitudinal direction as the side becomes further away. A display surface formed on a surface other than perpendicular to the road surface may display an image that expresses a sense of depth, with the display distance between the driver 4 and the virtual images V1, V2 varying depending on the display position on the display surface. For example, if the display surface is a surface inclined such that the left sides 8c, 9c and right sides 8d, 9d are inclined such that the upper sides 8b, 9b are positioned forward relative to the lower sides 8a, 9a, the driver 4 may recognize depth on the display surface.

In addition, information regarding the line of sight 4a of the driver 4 for calculating the display distance of the image, etc., may be preset and stored in the main control unit 40, etc., or, if the vehicle 1 or the display system 10 has a sensor that detects the line of sight of the driver 4, it may be detected by this sensor.

The upper HUD 20 has a display 21, a concave mirror 22, a housing 24, and an upper HUD display control unit 25.

The display 21 emits display light L1 toward the concave mirror 22. The display 21 is, for example, a TFT (Thin Film Transistor) type liquid crystal display or an organic EL (Electro Luminescence) display. The display 21 may also have a projector and a screen that forms a display surface.

The concave mirror 22 reflects the display light L1 emitted by the display 21 toward the windshield 3. The concave mirror 22 functions as a magnifying mirror, and magnifies the image displayed on the display 21 and reflects it toward the windshield 3. In other words, the driver 4 sees an enlarged version of the image displayed on the display 21.

The housing 24 supports a control board on which the concave mirror 22, the display 21, and the upper HUD display control unit 25 are mounted inside the housing 24.

The upper HUD display control unit 25 has a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and executes a predetermined calculation process according to a program written in the ROM. Specifically, the upper HUD display control unit 25 controls the display 21 to display a required image based on instructions from the main control unit 40.

The lower HUD 30 has a display 31, a housing 34, and a lower HUD display control unit 35.

The display 31 emits the display light L2 directly to the light-shielding portion 3a on the housing 34. The display 31 has a configuration similar to that of the upper HUD 20, for example. This allows the driver 4 to view the image displayed on the display 31 and reflected by the light-shielding portion 3a.

The housing 34 supports a control board on which the display 31 and the lower HUD display control unit 35 are mounted inside the housing 34.

The lower HUD display control unit 35 has a CPU, ROM, RAM, etc., and executes predetermined calculation processing according to a program written in the ROM. Specifically, the lower HUD display control unit 35 controls the display 31 to display a required image based on instructions from the main control unit 40.

The main control unit 40 controls the upper HUD 20 and the lower HUD 30, particularly based on information acquired from each part of the vehicle 1, which will be described later. The main control unit 40 has a CPU, ROM, RAM, etc., and executes predetermined calculation processing and display control processing, which will be described later, according to a program written in the ROM.

In addition to the display system 10, the vehicle 1 has a surrounding information acquisition unit 51, an outside-vehicle information acquisition unit 52, a car navigation system 53, a vehicle ECU (Electronic Control Unit) 54, and a reception unit 55. Each unit and the main control unit 40 are connected via, for example, a CAN (Controller Area Network) bus 50.

The surrounding information acquisition unit 51 acquires information about the surroundings (external) of the vehicle 1. The surrounding information acquisition unit 51 communicates between the vehicle 1 and a wireless network, between the vehicle 1 and other vehicles, between the vehicle 1 and pedestrians, and between the vehicle 1 and roadside infrastructure. For example, the surrounding information acquisition unit 51 includes a communication module that can directly access a WAN (Wide Area Network), a communication module for communicating with an external device (such as a mobile router) that can access the WAN, or an access point of a public wireless LAN (Local Area Network), and performs Internet communication.

The surrounding information acquisition unit 51 also includes a wireless communication module that complies with a specific wireless communication standard. Furthermore, the surrounding information acquisition unit 51 has a communication device that wirelessly communicates with roadside infrastructure, and acquires object information and traffic information from, for example, a base station of a driving safety support system (DSSS, Driving Safety Support Systems) via a roadside wireless device arranged as infrastructure.

The outside-vehicle information acquisition unit 52 detects the contents and positions of objects such as people, structures, and other vehicles 1 that exist in the external environment surrounding the vehicle 1 on all sides, above, below, in front, behind, and to the left and right of the vehicle 1. The outside-vehicle information acquisition unit 52 is, for example, a stereo camera that captures the scenery around the vehicle 1, a distance measurement sensor such as a LIDAR (Laser Imaging Detection and Ranging) that measures the distance from the vehicle 1 to an object, a sonar, ultrasonic sensor, millimeter wave radar, etc. that detects objects located around the vehicle 1.

The car navigation system 53 has a GPS (Global Positioning System) controller that calculates the position of the vehicle 1 based on GPS signals received from artificial satellites, etc. The car navigation system 53 has a memory unit that stores map data, and based on position information from the GPS controller, reads map data near the current position from the memory unit and determines a guide route to the destination set by the occupant. The car navigation system 53 outputs information related to the current position of the vehicle 1 and the determined guide route to the main control unit 40.

The car navigation system 53 also references map data to output to the main control unit 40 information indicating the names and types of facilities ahead of the vehicle 1 and the distance between the facilities and the vehicle 1. The map data associates various information with position data, such as road shape information (lanes, road width, number of lanes, intersections, curves, branching roads, etc.), road signs such as speed limits, traffic information regarding traffic regulations such as road closures, one-way traffic, and speed restrictions, and information about each lane when there are multiple lanes. The car navigation system 53 outputs this information to the main control unit 40.

The car navigation system 53 is not limited to being installed in the vehicle 1, but may be realized by a mobile terminal (e.g., a smartphone or tablet PC (Personal Computer)) with a car navigation function that communicates with the main control unit 40 via wired or wireless communication.

The vehicle ECU 54 acquires vehicle information necessary for the running of the vehicle 1, such as vehicle speed and engine RPM, from various sensors installed in the vehicle 1, and controls the operation of the vehicle 1. The vehicle ECU 54 outputs required vehicle information, such as vehicle speed and warning information about the vehicle 1 itself (e.g., low fuel, abnormal engine oil pressure), to the main control unit 40.

The reception unit 55 is a type of switch that is arranged on the instrument panel 2 or the steering wheel 5 and is operated by the driver 4. The reception unit 55 receives the setting values of the vehicle 1 from the driver 4. The driver 4 sets the setting values of the adaptive cruise control (hereinafter referred to as ACC) function of the vehicle 1 using the reception unit 55.

The ACC function is a driving assistance function that automatically enables the vehicle 1 to travel at a constant speed or follow the vehicle ahead (maintaining a constant distance from the vehicle ahead) without the driver 4 having to drive the vehicle 1, using the surrounding information acquisition unit 51, outside vehicle information acquisition unit 52, car navigation system 53, vehicle ECU 54, main control unit 40, etc. The setting values for the ACC function include an execution setting when using the ACC function, a vehicle speed setting that sets the vehicle speed when traveling at a constant speed, and a distance setting that sets the distance from the vehicle ahead when following the vehicle ahead.

Next, we will explain in detail how the display system 10 controls the display of the ACC function.

As shown in Figures 1 and 2, the display system 10 in this embodiment has an upper HUD 20 that displays an image at a position (close position) where the line of sight movement from the line of sight 4a of the driver 4 is small, making it easy for the driver 4 to recognize, and a lower HUD 30 that displays an image at a position (far position) where the line of sight movement from the line of sight 4a is larger than that of the upper HUD 20, making it relatively difficult for the driver 4 to recognize. The display system 10 links the upper HUD 20 and lower HUD 30 and displays the setting screen for the ACC function on the upper HUD 20, which is easy to recognize, and can appropriately convey information to the driver 4.

As shown in FIG. 3, the lower HUD display area 9 displays a host vehicle image 91 showing the host vehicle 1, a vehicle speed image 92 related to vehicle speed information acquired from the vehicle ECU 54, an image related to information related to vehicles surrounding the host vehicle 1 acquired from the outside information acquisition unit 52, etc., and a dividing line image 94 showing information related to dividing lines of the driving lane in which the host vehicle 1 is traveling. The image related to information related to the surrounding vehicles includes, for example, a rear vehicle image 95 related to information related to a rear vehicle traveling behind the host vehicle 1, and a front vehicle image 96 related to information related to a front vehicle traveling in front, and shows a relative positional relationship with the host vehicle image 91. The rear vehicle image 95 and the front vehicle image 96 are displayed when there is a rear vehicle and a front vehicle.

In addition, in the lower HUD display area 9, a sign image 97 related to information about road signs applied to the vehicle 1 currently traveling is displayed at the required timing. In this disclosure, the sign image 97 is a speed limit sign with a speed limit of 100 km/h. The content of the road sign may be a regulatory sign indicating prohibitions such as no overtaking, or information about other road signs. A plurality of sign images 97 may be displayed in the lower HUD display area 9, and in this case, it is preferable that the sign image 97 related to the speed limit with high importance is displayed in the center of the lower HUD display area 9, in an area that is easily recognized by the driver 4.

When the driver 4 uses the ACC function, the lower HUD display area 9 also displays the vehicle speed setting image 98 for constant speed driving described above, and the following distance setting image 99 for following the vehicle ahead described above. The following distance setting image 99 is made up of multiple rectangular designs (segments) and is arranged side by side between the forward vehicle image 96 and the vehicle image 91, and the number of designs indicates the distance between the vehicle ahead and the vehicle ahead.

Here, the forward vehicle image 96, the following distance setting image 99, the vehicle image 91, and the adjacent lane marking image 94 are collectively referred to as the ACC distance setting image. The ACC distance setting image and the vehicle speed setting image 98 are displayed when the driver 4 operates the reception unit 55 to set the ACC function to be executed, and when the execution setting is set, this is an emergency.

Here, the ACC distance setting image has a driver's eye view image (first image) E1, a bird's-eye view image (second image) E2, and an overhead view image (third image) E3, as shown in FIG. 4. The driver's eye view image E1 is an image of how the driver 4 sees the vehicle 1 and the vehicle ahead 100 from the first line of sight (similar to line of sight 4a in FIG. 1), which is the line of sight from the driver 4 looking at the vehicle ahead 100 from the vehicle 1 (viewed from an angle of 0 to approximately 10 degrees with respect to the road surface). The driver's eye view image E1 is the ACC distance setting image shown in FIG. 3.

Bird's-eye view image E2 is an image of how the vehicle 1 or the vehicle ahead 100 appears when viewed from a virtual second line of sight that is located higher than the first line of sight (looking down from approximately 60 degrees to approximately 90 degrees (directly above)). Bird's-eye view image E2 is the ACC distance setting image shown in FIG. 7. Bird's-eye view image E3 is an image of how the vehicle 1 or the vehicle ahead 100 appears when viewed from a virtual third line of sight that is located between the first and second lines of sight (looking down from an angle of approximately 10 to approximately 60 degrees). Bird's-eye view image E3 is the ACC distance setting image shown in FIG. 5 and FIG. 6.

When the driver 4 operates the reception unit 55 and detects a change in the following distance for the ACC function's following vehicle, the main control unit 40 moves the ACC distance setting image and the vehicle speed setting image 98 from the lower HUD display area 9 to the upper HUD display area 8, as shown in Figures 5 to 7.

At this time, in order to make the driver 4 more aware of the movement of the ACC distance setting image and the vehicle speed setting image 98, the main control unit 40 may, for example, cause the ACC distance setting image and the vehicle speed setting image 98 to flash, or may control the lower HUD display control unit 35 to dim the brightness of the display other than the ACC distance setting image and the vehicle speed setting image 98.

First, as shown in FIG. 5, the lower HUD display control unit 35 moves the ACC distance setting image and the vehicle speed setting image 98 linearly in the vertical direction toward the upper HUD display area 8. At this time, the ACC distance setting image moves while gradually switching from the driver's eye view image E1 to the overhead view image E3. The ACC distance setting image and the vehicle speed setting image 98 are cut off from the upper side 9b of the lower HUD display area 9.

Next, as shown in FIG. 6, the upper HUD display control unit 25 gradually makes the ACC distance setting image and the vehicle speed setting image 98 appear from the bottom edge 8a of the upper HUD display area 8. At this time, the ACC distance setting image is displayed so as to straddle both the lower HUD display area 9 and the upper HUD display area 8, thereby improving the sense of linkage between the displays of the upper HUD 20 and the lower HUD 30 and allowing the driver 4 to further recognize the movement of the ACC distance setting image.

Finally, as shown in FIG. 7, at the same time that the ACC distance setting image is completely erased from the lower HUD display area 9, the upper HUD display control unit 25 switches the ACC distance setting image in the upper HUD display area 8 from the overhead image E3 to the bird's-eye image E2. This allows the driver 4 to improve the visibility of the setting of the following distance. Also, by changing the ACC distance setting image from the driver's eye image E1 to the bird's-eye image E2 via the overhead image E3, the driver 4 can improve the recognition of the change in the line of sight of the image.

After that, when the driver 4 finishes operating the reception unit 55 and a predetermined time has elapsed, the main control unit 40 moves the ACC distance setting image and the vehicle speed setting image 98 from the upper HUD display area 8 to the lower HUD display area 9 in the order of Figures 7, 6, 5, and 3. At this time, the ACC distance setting image is also changed from the bird's-eye view image E2 to the driver's eye view image E1 via the overhead view image E3.

In order to make the ACC distance setting image and vehicle speed setting image 98 appear to be the same size as seen by the driver 4 in the upper HUD display area 8 and the lower HUD display area 9, the size of the ACC distance setting image and vehicle speed setting image 98 actually displayed in the lower HUD display area 9 is made larger than the size of the ACC distance setting image and vehicle speed setting image 98 actually displayed in the upper HUD display area 8.

Second Embodiment
A second embodiment of a display system according to the present disclosure will be described with reference to Fig. 8. The same parts and equivalent parts as those in the first embodiment will be denoted by the same reference numerals.

In the first embodiment, the main control unit 40 changed the ACC distance setting image from the driver's eye view image E1 to the overhead view image E3 in the lower HUD display area 9 and moved it to the upper HUD display area 8. However, in the present disclosure, when a change in the inter-vehicle distance when following a preceding vehicle is detected, the ACC distance setting image is changed from the driver's eye view image E1 to the bird's eye view image E2 in the lower HUD display area 9 via the overhead view image E3, and then the bird's eye view image E2 is moved to the upper HUD display area 8.

Even with this configuration, the driver 4 can improve visibility of the following distance setting.

Third Embodiment
A third embodiment of a display system according to the present disclosure will be described with reference to Fig. 9. The same parts and equivalent parts as those in the first embodiment will be denoted by the same reference numerals.

In this disclosure, when a change in the distance between vehicles is detected when following a vehicle ahead, the ACC distance setting image is changed from the driver's eye view image E1 in the lower HUD display area 9 to the upper HUD display area 8, and then in the upper HUD display area 8, the image is changed from the driver's eye view image E1 to the bird's eye view image E2 via the overhead view image E3.

Even with this configuration, the driver 4 can improve visibility of the following distance setting.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.

For example, an example has been described in which the first display (upper HUD 20) and the second display (lower HUD 30) are both HUDs, but one or both may be devices that allow the user to view a real image displayed on a display panel such as a TFT-type liquid crystal display or an organic EL display.

In addition, while an example has been described in which the projection member of the upper HUD 20 and the lower HUD 30 is the windshield 3, the projection member may instead be a combiner, or in addition to the windshield 3.

In addition, when changing from the driver's eye-view image E1 to the bird's-eye view image E2, images with gradually increasing line-of-sight angles may be sequentially transitioned. The change in line-of-sight angle at this time may be linear or non-linear. For example, when changing the line-of-sight angle non-linearly, a novel presentation can be provided to the driver 4 by first increasing the degree of change and then decreasing the degree of change as the image approaches the bird's-eye view image E2.

In addition, the ACC distance setting image includes the forward vehicle image 96, the following distance setting image 99, the vehicle image 91, and the adjacent lane marking image 94, but may be set arbitrarily without being limited to this. For example, the vehicle image 91 and the lane marking image 94 may not be included.

In addition, after detecting a change in the distance between the vehicles in front of the vehicle, the ACC distance setting image and the vehicle speed setting image 98 are moved from the lower HUD display area 9 to the upper HUD display area 8, but it is also possible to move only the ACC distance setting image.

In addition, while the bird's-eye view image E2 and the overhead view image E3 have different vertical gaze positions compared to the driver's eye view image E1, they may also have different horizontal gaze positions compared to the driver's eye view image E1. For example, when the driver 4 operates the reception unit 55 and detects a change in the following distance when following the vehicle ahead, the main control unit 40 may switch the ACC distance setting image to an image that shows the vehicle 1 or the vehicle ahead 100 as seen from directly to the side.
