Description

[Technical field]

[0001] The present disclosure relates to an information providing system for vehicles, an information providing method for vehicles, and a program. [Technical background]

[0002] With the advancement of vehicle information delivery systems in recent years, the number of in-vehicle displays within the vehicle interior has also increased. This trend has created a demand for technologies that use multiple in-vehicle displays to display enlarged application images, such as navigation and TV images, to enhance their visibility. Therefore, the size of an application image and the processing load for rendering tend to increase or decrease depending on the extent to which multiple in-vehicle displays collaborate.

[0003] The patent literature (PTL 1) discloses a distribution server that divides an image into sub-images on the receiving side and then displays the sub-images to reduce the load on the distribution side. [Quotation list][Patent literature]

[0004] [PTL 1] Unexamined Japanese Patent Application Publication No. 2020-161896 [Summary of the invention][Technical problem]

[0005] However, with the PTL 1 distribution server, the rendering processing load on the distribution side increases as the collaboration scale of multiple display devices increases. Therefore, this technology has a shortcoming in that it becomes impossible to display images shared across multiple display devices once the collaboration scale exceeds the rendering processing capacity on the distribution side.

[0006] Accordingly, the present disclosure is directed to providing an information providing system for vehicles, an information providing method for vehicles, and a program, each of which can curb an increase in rendering processing load across a plurality of cooperating display areas. [Solution to the problem]

[0007] An information providing system for vehicles according to one aspect of the present disclosure is an information providing system for vehicles that controls a display mode of an application image to be displayed in a first display area and a second display area provided in a vehicle. The information providing system for vehicles includes a display change determiner that determines division areas for dividing a zoomed-out application image to obtain blocks corresponding to the first display area and the second display area, respectively, such that the division areas have an aspect ratio equal to a resolution of the first display area and a resolution of the second display area, and a display control unit that sets and displays the blocks divided by the division areas to correspond to the first display area and the second display area, respectively.

[0008] Meanwhile, an information providing method for vehicles according to one aspect of the present disclosure is an information providing method for vehicles that controls a display mode of an application image to be displayed in a first display area and a second display area provided in a vehicle, the information providing method for vehicles comprising determining division areas for dividing a zoomed-out application image to obtain blocks corresponding to the first display area and the second display area, respectively, such that the division areas have an aspect ratio each equal to a resolution of the first display area and a resolution of the second display area, and setting and displaying the blocks divided by the division areas to correspond to the first display area and the second display area, respectively.

[0009] A program according to one aspect of the present disclosure is a program for causing a computer to execute an information providing method for vehicles. [Advantageous effects of the invention]

[0010] The information providing system for vehicles, etc. according to the present disclosure can curb an increase in rendering processing load in cooperative display areas.

[0011] The embodiments described below merely illustrate general or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection methods of components, steps, order of steps, etc. shown in the following embodiments are examples and are not intended to limit the present disclosure. Among the components described in the following embodiments, all components not recited in the independent claims are to be understood as optional components.

[0012] Furthermore, the drawings are schematic representations and do not necessarily provide an exact representation. Furthermore, identical components are identified by identical reference numerals.

[0013] An embodiment is described in more detail below with reference to the drawings. (Embodiment)<Konfiguration und Funktion>

[0014] First, the display system 1 according to the present embodiment will be described with reference to Fig. 1 to Fig. 6 described.

[0015] Fig. 1 is a schematic diagram of the display system 1 according to the embodiment provided in the vehicle 2. Fig. Fig. 2 is a block diagram showing the display system 1 according to this embodiment. Fig. 3 is a diagram showing how split blocks cut out from an application image are displayed separately in corresponding display areas in an enlarged view. Fig. 4 is a diagram showing how the area in which a block of an application image is displayed is changed in accordance with the control information. Fig. 5 is a diagram showing how an application image is displayed in a display area according to the frame rate. Fig. 6 is a diagram showing how information other than driving-related information is prevented from being displayed in a restricted display area. In Fig. 4 and Fig. 6, the first display device 41, the second display device 42 and the third display device 43 are shown as an example of a plurality of display devices 40.

[0016] As in Fig. 1, the display system 1 is a system for displaying one of a plurality of images on the screen of one or more display devices 40. In the display system 1, the position of each of a plurality of images displayed on the corresponding display screen of one or more display devices 40 can be adjusted automatically or manually by the vehicle occupant.

[0017] The display system 1 is used, for example, in a vehicle 2 in which one or more display devices 40 are provided. Therefore, according to the present embodiment, a plurality of images are images displayed based on applications and include information such as, but not limited to, a display instrument for the vehicle, an operating state of an on-board device, navigation information, a captured image, or information about the surroundings of the vehicle. A display instrument for the vehicle is, for example, a speedometer, a turn signal, a warning light, an odometer, a gear position indicator, a fuel gauge, or a water temperature gauge. An on-board device is, for example, but not limited to, an audio device, an on-board lighting device, or a seat device.Navigation information is, for example, but not exclusively, information that informs the driver of the current position of the moving vehicle 2 or guides the driver to a destination. A captured image is an image of the surroundings or interior of vehicle 2 captured by an imaging device provided in vehicle 2. Information about surrounding vehicles is information that indicates, for example, but not exclusively, the presence or absence, number, or speed of other vehicles in the vicinity of vehicle 2, or the distance from other vehicles of vehicle 2.

[0018] In detail, the display system 1 comprises a plurality of display devices 40, an operation input unit 21, a display content obtaining unit 22, a display restriction area determiner 23, a display adjuster 24, a driving information obtaining unit 25, a processing information obtaining unit 26, a performance evaluation unit 27, and a vehicle information providing system 10. In the Fig. 2, the display system 1 includes a first display device 41 and a second display device 42 as one example of the plurality of display devices 40. According to the present embodiment, the first display device 41 and the second display device 42 may be collectively referred to simply as display devices 40. In the description according to the present embodiment, the first display device 41 and the second display device 42 are mainly used as an example of the plurality of display devices 40 unless expressly indicated otherwise. Therefore, the plurality of display devices 40 according to the present embodiment is not limited to the first display device 41 and the second display device 42 and may include three or more display devices 40. The term "first display device 41 and second display device 42" may be replaced with a plurality of display devices 40. [First display device 41 and second display device 42]

[0019] The first display device 41 and the second display device 42 are each a display device, e.g., a personal computer (PC) equipped with a liquid crystal display or the like, a mobile terminal such as a smartphone, a car navigation system in a vehicle 2, an electronic mirror system, or a multi-information display.

[0020] In Fig. 1, as examples of the plurality of display devices 40, a car navigation system 40a arranged in the central portion in the vehicle width direction, an electronic mirror system functioning as a left side mirror 40b and a right side mirror 40c, and a plurality of multi-information displays 40d, 40e, and 40f are shown. These display devices 40 are arranged side by side so that an occupant of the vehicle 2 can view the plurality of display devices 40 simultaneously.

[0021] When a plurality of display devices 40 are provided side by side in the vehicle 2, the plurality of display devices 40 can collectively display a single image or each display a separate image because the plurality of display devices 40 are controlled by the display system 1 to cooperate with each other.

[0022] As in Fig. 2, the first display device 41 has a first display area 41a. The second display device 42, on the other hand, has a second display area 42a. In the example illustrated according to the present embodiment, one display device 40 has one display area. Alternatively, one display device 40 may have two or more display areas. In the description according to the present embodiment, the first display area 41a and the second display area 42a are mainly used as an example of a plurality of display areas unless expressly indicated otherwise. Therefore, the plurality of display areas according to the present embodiment is not limited to the two display areas of the first display area 41a and the second display area 42a, and may include three or more display areas.The expression “first display area 41a and second display area 42a” may be replaced by a plurality of display areas.

[0023] The first display area 41a and the second display area 42a each display a graphical user interface (GUI) for operating an image, such as a car navigation map, a menu image of various on-board devices, or a search image. [Operation input unit 21]

[0024] The operation input unit 21 is an input interface that receives input for a user operation. For example, the operation input unit 21 receives setting input from a user for processing and displaying an application image in each of the plurality of display areas. A setting input is, for example, but not limited to, a specific display on which a processed application image is to be displayed, a display mode of an application image in a specific display, or permission for dynamic setting change. The operation input unit 21 outputs a received setting input to the display adjuster 24. A specific display is a display area among the plurality of display areas in which a processed application image is to be displayed. A display mode is, for example, the display position of an application image or the size of an application image.Permission for dynamic setting change is described later. [Display content obtaining unit 22]

[0025] The display content obtaining unit 22 obtains an application image to be displayed in each of the plurality of display areas from an application or the like. The display content obtaining unit 22 outputs the obtained application image to the display restriction area determiner 23. [Display Restriction Area Determiner 23]

[0026] The display restriction area determiner 23 determines, from among the plurality of display areas, a display area other than the display area reserved for displaying driving-related information. In other words, the display restriction area determiner 23 determines the display area reserved for displaying driving-related information as the display restriction area. Driving-related information is information related to the driving safety of the vehicle 2, and is, for example, information about a display instrument for the vehicle. The display restriction area is a display area reserved for displaying driving-related information, in which no image other than driving-related information is displayed.This configuration may limit such a user-configured setting that causes an image other than the driving-related information to be displayed in the display area reserved for displaying the driving-related information.

[0027] Furthermore, the display restriction area determiner 23 determines a display area other than the display area reserved for displaying driving-related information as the display target area. A display target area is a display area other than the display area reserved for displaying driving-related information, and is, for example, an area in which the operating status of an onboard device or navigation information is displayed.

[0028] The display restriction area determiner 23 outputs an application image obtained from the display content obtaining unit 22 and area identification information for identifying the display restriction area to the display adjuster 24. [Advertiser 24]

[0029] The display setter 24 receives a setting input from the operation input unit 21 and receives an application image and area identification information from the display restriction area determiner 23. The display setter 24 generates setting information based on the setting input, the application image, and the area identification information. The setting information includes, but is not limited to, a specific display on which the application image is displayed, a display mode of the application image on the specific display, or permission for dynamic setting change. The display setter 24 outputs the application image and the setting information to the display change determiner 28. [Travel information receiving unit 25]

[0030] The driving information acquisition unit 25 receives driving information from, for example, an electronic control unit (ECU) or a sensor provided in the vehicle 2. The ECU includes, for example, a central processing unit (CPU) and a graphics processing unit (GPU). The driving information is information related to the driving of the vehicle 2. Specifically, the driving information includes, for example, the presence or absence of the driving state of the vehicle 2 by the user, the presence or absence of normal driving of the vehicle 2, or the driving speed of the vehicle 2.The driving state of the vehicle 2 by the user refers to the state in which the user operates the vehicle 2 cautiously, as opposed to normal driving, and includes, for example, a state in which the vehicle 2 is traveling slowly, a state in which the vehicle 2 is about to change its route, or a state in which the vehicle 2 is entering an intersection. Normal driving includes, for example, a case in which the vehicle 2 is traveling on an ordinary road or an expressway. The driving information obtaining unit 25 outputs the obtained driving information to the display change determiner 28. [Processing information obtaining unit 26]

[0031] The processing information obtaining unit 26 obtains, for example, processing information of the vehicle 2, for example, from the ECU provided in the vehicle 2. The processing information includes, for example, the CPU utilization rate, the GPU utilization rate, the used memory capacity, and the network bandwidth. The processing information obtaining unit 26 outputs the obtained processing information to the performance evaluation unit 27. [Performance Assessment Unit 27]

[0032] The performance evaluation unit 27 successively analyzes the obtained processing information and estimates the frame rate based on the processing information relating to each of the first display area 41a and the second display area 42a. The performance evaluation unit 27 outputs the estimated frame rate to the display change determiner 28. [Information provision system 10 for vehicles]

[0033] The vehicle information providing system 10 controls the display mode of an application image to be displayed in the first display area 41a and the second display area 42a of the vehicle 2. The vehicle information providing system 10 includes a display control unit 30 and a display change determiner 28 having a transmitter 29 capable of transmitting, for example, an application image to the display control unit 30. The display mode includes, for example, a specific display of an application image serving as a display target area, the display mode of the application image in the specific display, and a division area used when dividing and cutting out a block from the application image.

[0034] The display change determiner 28 receives an application image and setting information for displaying the application image in the display target area from the display setter 24, receives driving information from the driving information obtaining unit 25, and receives the image change frequency from the performance judging unit 27.

[0035] Furthermore, the display change determiner 28 determines the presence or absence of a display change based on the obtained setting information. If the obtained setting information indicates that a setting change should be made to the current setting, the display change determiner 28 determines that the user has indicated a display change. If there is a display change, the display change determiner 28 determines the display mode.

[0036] To process and display an application image in a display target area, the display change determiner 28 specifically determines the intended display of the application image serving as the display target area and the display mode of the application image. Furthermore, the display change determiner 28 determines the partial area of the application image in a reduced view such that the partial area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a. When determining the division area, the display change determiner 28 determines division areas for dividing the zoomed-out application image to obtain blocks corresponding to the first display area 41a and the second display area 42a, respectively. A block is at least a part of a zoomed-out application image.

[0037] For example, as in Fig. 3, the display change determiner 28 receives an application image that is zoomed out without changing the size of the application image. The display change determiner 28 determines the resolution of 960 × 540 for a partial area to divide the application image to obtain a block. Fig. 3, the display change determiner 28 determines the division areas for dividing the application image to obtain two blocks corresponding to the first display area 41a and the second display area 42a.

[0038] In this configuration, the display change determiner 28 determines the display mode that displays the specific display of the application image serving as the display target area, and the display mode and the division area for the application image, depending on the content of the setting input specified by the user.

[0039] The display change determiner 28 transmits a display event indicating the determined display mode and application image from the transmitter 29 to the display control unit 30.

[0040] As in Fig. 4, the display change determiner 28 may further determine one or more display target areas for displaying a block from the first display area 41a and the second display area 42a based on the travel information related to the travel of the vehicle 2. Furthermore, the display change determiner 28 may determine one or more partial areas for dividing an application image to obtain one or more blocks corresponding to the determined one or more display target areas, such that each partial area has an aspect ratio corresponding to the resolution of the first display area 41a and the resolution of the second display area 42a, respectively.

[0041] In the Fig. 4 in (a), in order to reduce the area in which the block of the application image is displayed, driving-related information is displayed on the third display device 43, navigation information is displayed on the first display device 41, and entertainment information is displayed on the second display device 42.

[0042] In the Fig. 4 in (b), in order to enlarge the display area of the application image, driving-related information is displayed on the third display device 43 and navigation information is displayed on the first display device 41 and the second display device 42.

[0043] For example, in the case described in (a) of Fig. 4 in contrast to the example shown in (b) of Fig. 4, when the driving information indicates, as the driving state of the vehicle 2 by the user, a case where the vehicle 2 is moving slowly or a case where the vehicle 2 is about to change its travel route, the display change determiner 28 may determine a display target area from the first display area 41a and the second display area 42a to reduce the area displaying the block of the application image (to reduce the area for display). The display change determiner 28 may determine a division area for dividing an application image to obtain a block corresponding to the determined display target area. The display change determiner 28 may generate a reduced display event, for example, based on the determined display target area and the determined division area.The display change determiner 28 can transmit the generated reduced display event from the transmitter 29 to the display control unit 30.

[0044] For example, in the case described in (b) of Fig. 4 in contrast to the example shown in (a) of Fig. 4, when the driving information indicates a case where the vehicle 2 is in normal driving, the display change determiner 28 may determine a display target area from the first display area 41a and the second display area 42a to enlarge the area displaying the block of the application image (to enlarge the area for display). The display change determiner 28 may determine a division area for dividing an application image to obtain a block corresponding to the determined display target area. The display change determiner 28 may generate an enlarged display event based, for example, on the determined display target area and the determined division area. The display change determiner 28 may transmit the generated enlarged display event from the transmitter 29 to the display control unit 30.

[0045] As in Fig. 5, the display change determiner 28 determines, in accordance with the frame rate estimated based on the processing information for the first display area 41a and the second display area 42a, division areas for dividing an application image to obtain blocks corresponding to the first display area 41a and the second display area 42a, respectively, such that each division area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a.

[0046] In particular, the display change determiner 28 may determine whether the estimated frame rate is higher than a predetermined threshold.

[0047] For example, as in (a) of Fig. As shown in FIG. 5, when the estimated frame rate is higher than or equal to a predetermined threshold (when the frame rate is high), the display change determiner 28 displays an application image in the display target area dot by dot. The predetermined threshold is, for example, 60 fps. Therefore, the display change determiner 28 may determine division areas for dividing the application image to obtain blocks corresponding respectively to the first display area 41a and the second display area 42a. The display change determiner 28 may determine the entire application image as the division area. The display change determiner 28 may generate a dot-by-dot display event to display an application image in the display target area dot by dot based on the determined division area.In other words, if the estimated frame rate is greater than or equal to the predetermined threshold, the display change determiner 28 may generate a dot-by-dot display event. The display change determiner 28 may transmit the generated dot-by-dot display event from the transmitter 29 to the display control unit 30.

[0048] For example, as in (b) of Fig. As shown in FIG. 5, when the estimated frame rate is lower than the predetermined threshold (when the frame rate is low), the display change determiner 28 displays a reduced application image in the display target area. Therefore, the display change determiner 28 may determine division areas for dividing the application image to obtain blocks corresponding respectively to the first display area 41a and the second display area 42a. The display change determiner 28 may generate a division-adapted display event to divide an application image based on the determined division area and display the divided application image in the display target area. In other words, when the estimated frame rate is lower than the predetermined threshold, the display change determiner 28 may generate a division-adapted display event.The display change determiner 28 can transmit the generated display event adapted to the pitch from the transmitter 29 to the display control unit 30.

[0049] When the display change determiner 28 receives a setting instruction to execute the division range determination, the display change determiner 28 can execute the division range determination. In other words, when the user has input a setting instruction to the operation input unit 21 to execute the division range determination, the display change determiner 28 can set the division range determination based on the drive information or set the division range determination according to the estimated frame rate.

[0050] As in Fig. 6, the display change determiner 28 determines a partial area in a display target area other than the display restriction area when the first display area 41a and / or the second display area 42a corresponds to the display restriction area reserved for displaying the driving-related information concerning the driving safety of the vehicle 2.

[0051] For example, when the image displayed in the first display area 41a or the second display area 42a is driving-related information, the display change determiner 28 refrains from setting the first display area 41a or the second display area 42a displaying driving-related information as at least one of the display target areas and refrains from designating this at least one area as a division area. In this case, the first display area 41a or the second display area 42a displaying driving-related information continues to display at least the existing information (driving-related information).

[0052] In the Fig. In the example shown in Figure 6, the third display device 43 displays the driving-related information, the first display device 41 displays the navigation information, and the second display device 42 displays the entertainment information. In this case, the display change determiner 28 refrains from setting the third display device 43 displaying the driving-related information as the display target area and refrains from designating this area as the division area. In this case, the third display device 43 displaying the driving-related information continues to display the driving-related information.

[0053] When the image displayed in the first display area 41a or the second display area 42a is at least not driving-related information, the display change determiner 28 sets the display area displaying this image as a display target area and determines a partial area.

[0054] In the Fig. In the example shown in FIG. 6, the display change determiner 28 sets the second display device 42, which displays the entertainment information as an example of a block of an application image, as the display target area and determines a partial area. In this case, the navigation information serving as an example of a block of an application image is displayed in the second display area 42a of the second display device 42 that displays the entertainment information.

[0055] The display control unit 30 controls the display mode of an application image to be displayed in the display target areas of the plurality of display devices 40. In other words, the display control unit 30 adjusts the divided blocks of an application image divided by the division area so that the divided blocks correspond to the first display area 41a and the second display area 42a, and performs control of displaying the blocks in the first display area 41a and the second display area 42a.

[0056] The display control unit 30 comprises the receiver 31, the zoom control unit 32, the generator 33, the splitter 34, the enlarger / reducer 35 and the combiner 36.

[0057] The receiver 31 is a communication module that can communicate with the display change determiner 28. The receiver 31 receives an application image, a display event, a reduced display event, an enlarged display event, a point-by-point display event, or a pitch-adjusted display event transmitted from the transmitter 29 of the display change determiner 28. The receiver 31 outputs each of these events received from the transmitter 29 of the display change determiner 28 to the zoom control unit 32.

[0058] As in Fig. 3, in response to receiving each event, the zoom control unit 32 zooms out or in (adjusts the zoom) a received application image as needed so that the resulting image has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a. The zoom control unit 32 outputs the zoomed application image and each event to the generator 33. As an example, in Fig. 3 shows a zoomed-out application image.

[0059] There may be a case where the zoom control unit 32 omits adjusting the zoom of an application image. In this case, the zoom control unit 32 may output an application image to the generator 33 without adjusting the zoom of the application image.

[0060] In response to receiving a zoomed application image and each event from the zoom control unit 32, the generator 33 executes a rendering process to display the zoomed application image in a display area based on the zoomed application image. The generator 33 outputs the rendered application image and each event to the divider 34.

[0061] In response to receiving the rendered application image and each event from the generator 33, the splitter 34 cuts and divides the rendered application image based on the display event among the received events. Specifically, the splitter 34 divides the application image to obtain blocks corresponding to the first display area 41a and the second display area 42a, corresponding to the partial areas displayed by the display event. The splitter 34 outputs each of the divided blocks and each event to the enlarger / reducer 35.

[0062] In response to receiving each of the divided blocks and each event from the divider 34, the enlarger / reducer 35 adjusts each of the divided blocks so that the blocks correspond to the first display area 41a and the second display area 42a, for example, based on the display event among the received events. For example, the enlarger / reducer 35 adjusts the size of each block by enlarging or reducing it while maintaining the aspect ratio so that the blocks correspond to the first display area 41a and the second display area 42a. The enlarger / reducer 35 outputs each of the adjusted blocks to the combiner 36. In the Fig. 3, each of the blocks has been adjusted by enlarging it so that the blocks correspond to the first display area 41a and the second display area 42a.

[0063] In response to receiving each of the adjusted blocks from the enlarger / reducer 35, the combiner 36 performs a combination process and outputs each of the blocks that have undergone the combination process to the display target areas of the corresponding target display device. In this operation, the adjusted blocks are displayed in the first display area 41a of the first display device 41 and the second display area 42a of the second display device 42, as shown in Fig. 3 shown. <verarbeitungsbetrieb>

[0064] The operation of the vehicle information providing system 10, the vehicle information providing method and the program according to the present embodiment will be described with reference to Fig. 7 described.

[0065] Fig. 7 is a sequence diagram showing a processing operation of the vehicle information providing system 10 according to this embodiment.

[0066] First, the display change determiner 28 receives from the display setter 24 an image to be displayed in a display target area, setting information set by the display setter 24, and setting information set based on the image and the area identification information (S11).

[0067] Next, if a dynamic setting change is allowed in the obtained setting information, the display change determiner 28 creates a thread for monitoring (S12).

[0068] Next, to display a block of an application image in a display target area, the display change determiner 28 determines the designated display of the application image serving as the display target area and the display mode of the application image. Furthermore, the display change determiner 28 determines the partial area of a zoomed-out application image such that the partial area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a. At this time, when at least one of the first display area 41a and the second display area 42a corresponds to the restricted display area reserved for displaying driving-related information, the display change determiner 28 determines the dividing area in a display target area other than the restricted display area.With this configuration, the display change determiner 28 determines the intended display of the application image serving as the display target area and the display mode indicating the display mode of the application image and the split area according to the content of the setting input provided by the user. The display change determiner 28 transmits a display event indicating the determined display mode and the application image from the transmitter 29 to the display control unit 30 (S13).

[0069] Meanwhile, if a dynamic setting change is permitted in the setting information in step S12, the display change determiner 28 receives driving information from the driving information obtaining unit 25 and analyzes and monitors the obtained driving information (S21). In other words, by analyzing driving information each time the display change determiner 28 receives driving information, the display change determiner 28 monitors the driving information. Specifically, the display change determiner 28 monitors, for example, the presence or absence of the user's driving state of vehicle 2, the presence or absence of normal driving of vehicle 2, or a change in the driving speed of vehicle 2 each time the display change determiner 28 receives driving information.

[0070] For example, in the case of (a) Fig. 4, in contrast to the example shown in (b) of Fig. 4, when the driving information indicates, as the driving state of the vehicle 2 by the user, a case where the vehicle 2 is moving slowly or a case where the vehicle 2 is about to change its travel route, the display change determiner 28 determines a display target area from the first display area 41a and the second display area 42a in order to reduce the area displaying the block of the application image. Specifically, when the block of the application image is displayed in the first display area 41a and the second display area 42a, the display change determiner 28 determines the first display area 41a or the second display area 42a as the display target area. As shown in (a) of Fig. 4, navigation information is displayed in the first display device 41 to reduce the area in which the block of the application image is displayed.

[0071] Furthermore, the display change determiner 28 determines the division area for dividing the application image to obtain a block corresponding to the determined display target area. Specifically, the display change determiner 28 determines the division area for dividing the application image to obtain a block corresponding to the first display area 41a or the second display area 42a serving as the display target area. The display change determiner 28 generates a reduced display event based on the determined display target area and the determined division area. The display change determiner 28 transmits the generated reduced display event from the transmitter 29 to the display control unit 30 (S22).

[0072] For example, in the case of (b) Fig. 4, in contrast to the example shown in (a) of Fig. In the example shown in Fig. 4, when the driving information indicates that the vehicle 2 is in normal driving, the display change determiner 28 determines the display target area from the first display area 41a and the second display area 42a to enlarge the area displaying the application image block. Specifically, when the application image block is displayed in the first display area 41a, the display change determiner 28 determines the second display area 42a as well as the first display area 41a as the display target area. As shown in (b) of Fig. 4, navigation information (an application image) is displayed in the first display device 41 and the second display device 42 to enlarge the area displaying the block of the application image.

[0073] Furthermore, the display change determiner 28 determines the division area for dividing the application image to obtain a block corresponding to the determined display target area. Specifically, the display change determiner 28 determines the division areas for dividing the application image to obtain blocks corresponding respectively to the first display area 41a and the second display area 42a serving as display target areas. The display change determiner 28 generates an enlarged display event based on the determined display target area and the determined division area. The display change determiner 28 transmits the generated enlarged display event from the transmitter 29 to the display control unit 30 (S23).

[0074] Meanwhile, if a dynamic setting change is permitted in the setting information in step S12, the display change determiner 28 obtains the frame rate (FPS) from the performance judgment unit 27. In other words, by analyzing processing information each time the performance judgment unit 27 receives processing information, the performance judgment unit 27 monitors the processing information (S31). Specifically, the performance judgment unit 27 monitors a change in the frame rate by repeatedly estimating the frame rate each time the performance judgment unit 27 receives driving information.

[0075] In addition, the display change determiner 28 determines whether the estimated frame rate is higher than a predetermined threshold.

[0076] For example, as in (a) of Fig. As shown in Figure 5, when the estimated frame rate is higher than or equal to a predetermined threshold, the display change determiner 28 generates a dot-by-dot display event for displaying an application image in the display target area dot-by-dot. The display change determiner 28 transmits the generated dot-by-dot display event from the transmitter 29 to the display control unit 30 (S32).

[0077] For example, as in (b) of Fig. As shown in Figure 5, when the estimated frame rate is lower than the predetermined threshold, the display change determiner 28 generates a split customized display event for splitting an application image based on the determined splitting area and adjusting and displaying the split application image in the display target area. The display change determiner 28 transmits the generated split customized display event from the transmitter 29 to the display control unit 30 (S33).

[0078] Next, the display control unit 30 receives the application image and each event. For example, the display control unit 30 receives the display event from step S13. If the dynamic setting change is permitted in the setting information in step S12, the display control unit 30 also receives the reduced display event or the enlarged display event, and the dot-by-dot display event or the pitch-adjusted display event. The display control unit 30 analyzes the received application image and each of the received events (S41).

[0079] Next, the display control unit 30 executes the process of each event (S42).

[0080] When the display control unit 30 executes the display event, the display control unit 30 performs the rendering process by reducing the received application image, cutting out each block from the application image subjected to the rendering process according to the partial area displayed by the display event, and outputting each block to the display devices 40 after adjusting it so that the block corresponds to the display target area. In this operation, the adjusted blocks are displayed in the first display area 41a of the first display device 41 and the second display area 42a of the second display device 42, as shown in Fig. 3 shown.

[0081] When the display control unit 30 executes the "reduced display" event, the display control unit 30 displays a block in the display target area to reduce the display area, for example, based on the display target area and the division area determined by the display change determiner 28. For example, in (a) of Fig. 4 the first display area 41a (the display target area) displays the navigation information and the second display area 42a displays the entertainment information to reduce the display area.

[0082] When the display control unit 30 executes the "enlarged display" event, the display control unit 30 displays a block in the display target area to enlarge the display area, for example, based on the display target area and the division area determined by the display change determiner 28. For example, in (b) of Fig. 4, the first display area 41a and the second display area 42a (the display target area) display the navigation information to enlarge the display area.

[0083] When the display control unit 30 executes the dot-by-dot display event, the display control unit 30 displays the application image dot by dot in the display target area based on the division area determined by the display change determiner 28. For example, in (a) of Fig. 5 the first display area 41a and the second display area 42a display the application image point by point.

[0084] When the display control unit 30 executes the split and adjusted display event, the display control unit 30 displays the application image in the form of split blocks in the target area of the display based on the split area determined by the display change determiner 28. For example, in (b) of Fig. 5 the zoomed out application image is split to get blocks, and the blocks are adjusted and displayed in the display target area.

[0085] Here, the permission for dynamic setting change in step S12 is optional. Therefore, if the dynamic setting change is not permitted in the setting information according to the setting input provided by the user, the display change determiner 28 does not need to execute the above-described steps S12 and S21 to S23 and / or S12 and S31 to S33. <Wirkung und vorteilhafte Effekte>

[0086] Next, the operation and advantageous effects of the vehicle information providing system 10, the vehicle information providing method, and the program according to the present embodiment will be described.

[0087] As described above, the information providing system 10 for vehicles according to the present embodiment is an information providing system 10 for vehicles that controls the display mode of an application image to be displayed in a first display area 41a and a second display area 42a provided in the vehicle, and the information providing system 10 for vehicles includes a display change determiner 28 that determines division areas for dividing a zoomed-out application image to obtain blocks corresponding to the first display area 41a and the second display area 42a, respectively, such that each division area has an aspect ratio corresponding to the resolution of the first display area 41a and the second display area 42a, respectively.the resolution of the second display area 42a, and a display control unit 30 which sets and displays the block divided according to the divided area, such that the block corresponds to both the first display area 41a and the second display area 42a.

[0088] According to this configuration, a widescreen application image created by reducing the size of an application image without changing the size of the application image is used, so that enlargement of the application image can be prevented. Furthermore, when using the widescreen application image, the division area can be determined to have an aspect ratio corresponding to the resolution of the first display area 41a and the resolution of the second display area 42a, respectively.

[0089] Accordingly, an increase in rendering processing load in a variety of collaborating display areas can be contained.

[0090] In particular, when using the widescreen application image generated by zooming out from the application image, a task in the application image is finely divided, so that the displayed image does not look rough even if the block divided after the division area is adjusted and displayed in the display area.

[0091] In addition, since the block of the application image can be displayed together in a plurality of display areas including a first display area 41a and a second display area 42a, an improvement in visibility to the user is expected.

[0092] Meanwhile, the information providing method for vehicles according to the present embodiment is an information providing method for vehicles that controls the display mode of an application image to be displayed in a first display area 41a and a second display area 42a provided in a vehicle 2, and the information providing method for vehicles includes determining division areas for dividing a zoomed-out application image to obtain respective blocks corresponding to the first display area 41a and the second display area 42a, such that each division area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a, and setting and displaying the blocks divided according to the division areas, such that the blocks correspond to the first display area 41a and the second display area 42a, respectively.

[0093] This method also provides similar working methods and beneficial effects as those described above.

[0094] The program according to the present embodiment is a program that causes a computer to execute the information providing method for vehicles.

[0095] This program also provides similar working methods and beneficial effects as those described above.

[0096] Moreover, in the information providing system 10 for vehicles according to the present embodiment, the display change determiner 28 determines the partial areas for dividing the application image to obtain blocks respectively corresponding to the first display area 41a and the second display area 42a so that each partial area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a, in accordance with the frame rate estimated after processing information related to each of the first display area 41a and the second display area 42a.

[0097] According to this configuration, when the frame rate is sufficiently high (e.g., when the frame rate is equal to or higher than a predetermined threshold), the utilization rate of, e.g., the CPU or GPU is considered low, and thus the application image can be displayed point by point.

[0098] Meanwhile, when the frame rate is low (e.g., when the frame rate is lower than the predetermined threshold), the utilization ratio of, for example, the CPU or the GPU is considered high. Therefore, when using a widescreen application image generated by zooming out from the application image without changing the size of the application image, the division area can be determined so that the aspect ratio is equal to the resolution of the first display area 41a and the resolution of the second display area 42a, respectively. Therefore, an increase in the rendering processing load in a plurality of collaborative display areas can be contained.

[0099] Moreover, in the information providing system 10 for vehicles according to the present embodiment, the display change determiner 28 determines, from the first display area 41a and the second display area 42a, one or more display target areas for displaying a block according to the travel information related to the travel of the vehicle 2, and determines the partial areas for dividing the application image to obtain one or more blocks corresponding to the determined one or more display target areas such that the one or more blocks have the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a.

[0100] According to this configuration, one or more display target areas can be determined depending on the driving state of the vehicle 2, and thus the one or more display target areas for displaying the blocks of the application image can be dynamically changed depending on the driving state of the vehicle 2. Since the blocks of the application image can be displayed in the one or more cooperative display target areas, an improvement in user visibility is expected.

[0101] Moreover, in the information providing system 10 for vehicles according to the present embodiment, when the driving information indicates the driving state of the vehicle 2 by the user, the display change determiner 28 determines the display target area to reduce the area displaying the block of the application image.

[0102] According to this configuration, since the user is likely to grasp the situation on the road around the vehicle 2 when the driving information indicates the driving state of the vehicle 2 by the user, the display target area is determined so that the area displaying the block of the application image is reduced. For example, either the display area of the first display area 41a or the second display area 42a is determined as the display target area. Therefore, the user can grasp the situation on the road around the vehicle 2, so an improvement in user visibility is expected.

[0103] Moreover, in the information providing system 10 for vehicles according to the present embodiment, when the driving information indicates the normal driving of the vehicle 2, the display change determiner 28 will determine the display target area to enlarge the area displaying the block of the application image.

[0104] With this configuration, since the user is likely to grasp the situation of the road extending far from vehicle 2 when vehicle 2 is in normal driving, the display target area is determined to enlarge the area displaying the block of the application image. For example, the two display areas of the first display area 41a and the second display area 42a are determined as display target areas. Therefore, the user can grasp the situation of the road extending far from vehicle 2, and thus, an improvement in user visibility can be expected.

[0105] Moreover, in the vehicle information providing system 10 according to the present embodiment, when the first display area 41a and / or the second display area 42a corresponds to the display restriction area reserved for displaying the driving-related information related to the driving safety of the vehicle 2, the display change determiner 28 determines the division area in the display target area other than the display restriction area.

[0106] According to this configuration, the restricted display area that displays driving-related information can be excluded from the cooperation of the multiple display areas, even if the user provides such a setting input to the vehicle information providing system 10. Accordingly, the vehicle information providing system 10 can provide driving-related information to the user.

[0107] Furthermore, in the information providing system 10 for vehicles according to the present embodiment, when the display change determiner 28 has a setting instruction to execute the determination of the division range, the display change determiner 28 will execute the determination of the division range.

[0108] After this configuration, it can be determined based on the user's preference whether to perform the determination of the division area so that the division area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a in accordance with the frame rate.

[0109] In addition, it can be set according to the user's preference whether to perform the determination of the division area so that the division area has the same aspect ratio as the resolution of the first display area 41a and the resolution of the second display area 42a in accordance with the control information. (Variation of the embodiment)

[0110] The present variation differs from the embodiment in that the display target area is redetermined according to the traveling speed of the vehicle 2. Other configurations according to the present variation are similar to those of the embodiment unless expressly indicated otherwise; therefore, identical configurations are denoted by identical reference numerals, and a detailed description of such configurations is omitted.

[0111] First, the display system 1 according to the present variation will be described with reference to Fig. 8 described.

[0112] Fig. 8 is a diagram showing how an area in which a block of an application image is displayed is changed according to the traveling speed of the vehicle 2.

[0113] The display change determiner 28 according to the present variation may redetermine, from the first display area 41a and the second display area 42a, one or more display target areas for displaying a block according to the traveling speed of the vehicle 2. Furthermore, the display change determiner 28 may determine the division areas for dividing an application image to obtain one or more blocks corresponding to the determined one or more display target areas, such that the division area has the same aspect ratio as each of the resolutions of the one or more display target areas.

[0114] For example, as in the Fig. 8, the display change determiner 28 may determine a display target area from the first display area 41a and the second display area 42a to reduce the area displaying one block of the application image as the traveling speed of the vehicle 2 decreases.

[0115] Specifically, when the traveling speed of the vehicle 2 is less than or equal to a first threshold, the display change determiner 28 may determine a display target area from the first display area 41a or the second display area 42a to reduce the area displaying the block of the application image. For example, in the Fig. 8, the display magnification of the application image is increased by 200% compared to the magnification of the normal display without changing the size of the application image. Then, the display change determiner 28 can determine the partial area for dividing the application image to obtain a block corresponding to each of the determined one or more display target areas. The display change determiner 28 can generate a reduced display event based on the determined one or more display target areas and the determined division area. In other words, in order to Fig. To obtain the narrow display range shown in Figure 8, the display change determiner 28 may generate a reduced display event when the traveling speed of the vehicle 2 is less than or equal to the first threshold. The display change determiner 28 may transmit the generated reduced display event from the transmitter 29 to the display control unit 30.

[0116] For example, as in the Fig. 8, the display change determiner 28 may determine a display target area from the first display area 41a and the second display area 42a to enlarge the area displaying one block of the zoomed-out application image as the traveling speed of the vehicle 2 increases.

[0117] Specifically, when the traveling speed of the vehicle 2 is higher than a second threshold, the display change determiner 28 may determine the first display area 41a and the second display area 42a as display target areas to enlarge the area displaying the block of the zoomed-out application image. For example, in the Fig. 8, the display magnification of the zoomed-out application image is reduced by 50% compared to the magnification of the normal display, without changing the size of the zoomed-out application image. Then, the display change determiner 28 may determine the division areas for dividing the zoomed-out application image to obtain blocks corresponding respectively to the determined first display area 41a and the second display area 42a. The display change determiner 28 may generate an enlarged display event based on the determined display target area and the determined division area. In other words, the display change determiner 28 may generate the enlarged display event when the traveling speed of the vehicle 2 is higher than the second threshold. The display change determiner 28 may transmit the generated enlarged display event from the transmitter 29 to the display control unit 30.

[0118] For example, as in the normal display in Fig. 8, when the traveling speed of the vehicle 2 is higher than the first threshold but lower than or equal to the second threshold, the display change determiner 28 may determine the existing display area as the display target area so as not to change the area displaying the block of the application image. Fig. In the normal display shown in Figure 8, the current display magnification of the application image is retained. Then, the display change determiner 28 may determine the partial area for dividing the application image to obtain a block corresponding to the determined existing display area. The display change determiner 28 may proceed with the display event executed based on the determined display target area and the determined division area. In other words, when the traveling speed of the vehicle 2 is higher than the first threshold but lower than or equal to the second threshold, the display change determiner 28 may proceed with the executed display event.

[0119] In the information providing system 10 for vehicles according to the present variation configured as above, the display change determiner 28 newly determines, from the first display area 41a and the second display area 42a, one or more display target areas for displaying a block based on the traveling speed of the vehicle 2, and determines the partial areas for dividing the application image to obtain one or more blocks corresponding to the one or more determined display target areas, such that the partial area has the same aspect ratio as each of the resolutions of the one or more display target areas.

[0120] According to this configuration, one or more display target areas can be redetermined depending on the traveling speed of the vehicle 2, and thus the one or more display target areas for displaying the blocks of the application image can be dynamically changed depending on the traveling speed of the vehicle 2. Since the blocks of the application image can be displayed in the one or more cooperative display target areas, an improvement in user visibility can be expected.

[0121] Moreover, in the information providing system 10 for vehicles according to the present variation, the display change determiner 28 will redetermine the display target area to enlarge the area displaying the block of the zoomed-out application image as the traveling speed of the vehicle 2 increases.

[0122] According to this configuration, since the user is likely to grasp the situation of the road extending far from vehicle 2 when the traveling speed of vehicle 2 increases, the display target area can be determined so as to enlarge the area displaying the block of the application image.

[0123] Accordingly, the user can grasp the situation of the road far away from vehicle 2 when the driving speed of vehicle 2 increases.

[0124] Since the user is likely to want to grasp the situation on the road around the vehicle 2 as the traveling speed of the vehicle 2 decreases, the target area of the display may be determined so as to reduce the area in which the block of the application image showing the surroundings of the vehicle 2 is displayed.

[0125] Accordingly, the user can grasp the situation on the road around vehicle 2 when the driving speed of vehicle 2 decreases.

[0126] This can be expected to improve visibility for the user. (Other variations)

[0127] So far, the vehicle information providing system, vehicle information providing method, and program according to the present disclosure have been described based on the foregoing embodiment and the variation of the embodiment.
