SUMMARY OF THE INVENTION

It is an object of the present disclosure to provide a vehicle display device that can give the driver a realistic feeling and can reduce difficulties in reading required information.

It is also an object of the present disclosure to provide a display control device that can display a three-dimensional instrument image and can reduce deterioration in the visibility of vehicle information due to the separation between a display area and a pointer.

According to an aspect of the present disclosure, a vehicle display device is provided. The vehicle display device has a display section attached to a vehicle, a driver information acquisition section, an image data acquisition section, and a reproduction section. The driver information acquisition section acquires a position of a viewpoint-related part provided by a driver's viewpoint or a point moving along with the viewpoint. The image data acquisition section acquires image data for generating a display image to be displayed on the display section. The display section generates the display image based on the image data and displays the display image on the display section. The image data is classified into motion suppression image data and motion promotion image data. The reproduction section determines an amount of movement of the display image generated from the movement promotion image data based on a change amount of the position of the viewpoint-related part. The playback section causes the amount of movement of the display image generated from the movement promotion image data to be larger than one Movement amount of the display image generated from the motion suppression image data.

With the vehicle display device, the display image generated from the movement promotion image data is determined on the basis of the position change amount of the viewpoint-related part. The movement amount of the display image generated from the movement promotion image data is larger than the movement amount of the display image generated from the movement suppression image data. Therefore, it is possible to give a driver a realistic feeling compared to a case where the moving amount of all the display images is equal to the moving amount of the display images generated from the motion suppression image data. The movement amount of the display images generated from the movement suppression image data is less than the movement amount of the movement promotion image data. Image data required for reading necessary information is classified as the motion suppressing image data, thereby suppressing difficulties in reading the necessary information.

According to another aspect of the present disclosure, a vehicle display device is provided. The vehicle display device has a display section, a vehicle acceleration detection section, an image data detection section, and a reproduction section. The display section is attached to a vehicle. The vehicle acceleration detection section detects an acceleration occurring on the vehicle. The image data acquisition section acquires image data for generating a display image to be displayed on the display section. The display section generates the display image based on the image data and displays the display image on the display section. The image data is classified into motion suppression image data and motion promotion image data. The reproduction section determines an amount of movement of the display image generated from the movement promotion image data based on the acceleration detected by the vehicle acceleration detection section. The reproducing section causes the amount of movement of the display image generated from the movement promotion image data to be larger than a movement amount of the display image generated from the movement suppression image data.

The vehicle display device is used to determine a display image generated from the movement promotion image data on the basis of an acceleration occurring on the vehicle. The movement amount of the display image generated from the movement promotion image data is larger than the movement amount of the display image generated from the movement suppression image data. Therefore, it is possible to give a driver a realistic feeling compared to a case where the moving amount of all the display images is equal to the moving amount of the display images generated from the motion suppression image data. The movement amount of the display images generated from the movement suppression image data is less than the movement amount of the movement promotion image data. Image data required for reading necessary information is classified as the motion suppressing image data, thereby suppressing difficulties in reading the necessary information.

According to another aspect of the present invention, a vehicle display device is provided. The display control device causes a monitor attached to a vehicle to display an image of an instrument that displays predetermined vehicle information related to driving control of the vehicle. The display control device has a vehicle information acquisition section, a stereoscopic instrument model generation section, and a reproduction section. The vehicle information acquisition section acquires the vehicle information. The stereoscopic instrument model creating section, as a stereoscopic model of the instrument, creates a stereoscopic instrument model by combining a base plate object, a plurality of scale objects and a pointer object. The base plate object is provided as a stereoscopic model of a base plate that represents an outer configuration of a scale surface of the instrument. Each of the plurality of scale objects is provided as a stereoscopic model of a corresponding one of a plurality of scales that are provided for the scale area. The pointer object is provided as a stereoscopic model of a pointer of the instrument and with a pointer body portion. The rendering section causes the monitor to display an image of the stereoscopic instrument model. The stereoscopic instrument model generating section places the pointer body section of the pointer object in a plane that faces the base plate object at a predetermined separation distance. The pointer body portion of the pointer object points to a state corresponding to the vehicle information acquired by the vehicle information acquisition portion. The stereoscopic instrument model generation section causes at least one of the plurality of scale objects that is closest to the pointer object to protrude from the base plate object by a predetermined amount that is less than or equal to the separation distance.

With the display control device, the stereoscopic instrument model generating section generates the stereoscopic model (or the stereoscopic instrument model) for the instrument such that the stereoscopic model has at least the scale near the pointer protruding from the base plate. The stereoscopic model causes the distance between the pointer and the scale close to the pointer to be less than the depth the separation distance between the base plate and the pointer.

It is possible to suppress the misalignment between the scale and the pointer even if the display section is similar to that in Patent Document 1 and displays an image of the stereoscopic instrument model from the viewpoint of the occupant, e.g. looks diagonally at the monitor. The visibility of the vehicle information can be prevented from deteriorating due to the separation between the base plate and the pointer. The base plate here describes an element that is comparable to the above-mentioned display area without scales. That is, the separation between the base plate and the pointer is comparable to the separation between the display surface and the pointer.

A predetermined separation distance is provided as a gap between the base plate and the pointer body portion. The stereoscopic instrument model can express a sense of depth corresponding to the separation distance. A sense of depth can be better expressed because the above configuration uses the mode to also display the scale object itself protruding from the base plate. This mode of displaying instrument images can provide the occupant with a three-dimensional appearance.

The above-mentioned configuration can display three-dimensional instrument images and prevent deterioration of the visibility of vehicle information due to the separation between the display area and the pointer.

EMBODIMENTS FOR CARRYING OUT THE INVENTION

In order to give the driver a more realistic feeling than a device disclosed in Patent Document 1, one might think that an image displayed on the display section is responsive to movement of a driver's viewpoint or head, or vehicle acceleration that is the viewpoint or Head moves, massive moves. However, when an image displayed on the display section is massively moved in a case where the driver's viewpoint is moving, the image deteriorates visibility. The configuration can result in the driver being provided with necessary information, such as the vehicle speed displayed on a speedometer can be read less easily.

A tangible, i.e. actual analog measuring device generally includes a pointer that is placed opposite a display surface to keep a constant distance from the display surface so that the pointer can rotate. In other words, there is a constant depth gap between the display surface and a plane for rotating the pointer.

The device disclosed in Patent Document 1 also generates a stereoscopic instrument model that represents the distance between the display surface and the pointer and displays an image from the direction of a driver's line of sight, so that an instrument image on the monitor is as realistic as possible as a tangible analog measuring device (Counter) is displayed. When an occupant looks obliquely at the monitor in the configuration that represents the distance between the display surface and the pointer, a scale attached to the display surface and the pointer are displaced or misaligned so that the occupant is given a three-dimensional appearance.

A three-dimensional appearance is created when the display surface and the pointer are placed separately and the scale and the pointer are offset due to the occupant eye positions. However, the configuration can hinder an exact match between the scale (or a numerical value) and the pointer.

The positional shift between the scale and the pointer can be reduced by reducing the distance between the display surface and the pointer, even if an occupant e.g. viewed at an angle. However, decreasing the distance between the display area and the pointer reduces variation in the display mode according to the occupant eye position (or occupant head position) and decreases the value of the dynamic display control in consideration of the occupant eye positions.

A correspondingly large distance between the display surface and the pointer is advantageous for the display control, taking into account the occupant eye positions. It is then possible to increase the degree of variation in the display mode according to the occupant eye positions and to provide the driver with a three-dimensional appearance.

In the above example, the pointer and the scale are misaligned or misaligned in the configuration for displaying a three-dimensional model from the driver's point of view, on the condition that the occupant's point of view is different from one in one direction (e.g., obliquely) Front direction for the monitor is located, but is not limited to this. The same concept also applies to a configuration that displays an image of a three-dimensional model in a predetermined posture regardless of the driver's point of view with respect to the aesthetic appearance, and displays a stereoscopic instrument model including the display surface held at an angle to the display surface of the monitor.

(First embodiment)

Embodiments are described below with reference to the accompanying drawings. 1 Fig. 12 shows a configuration of a vehicle display device 1 according to a first embodiment. The vehicle display device 1 is mounted on a vehicle. The vehicle display device 1 assigns a monitor 10th , an image data storage section 20th , a line-of-sight detection device 30th and a computing device 40 on.

The information is displayed as an image. One on the monitor 10th The image displayed is referred to below as the display image. The display image contains not only photos that show shapes in detail, but also geometrical figures, illustrations and drawings. On the monitor 10th a character is also displayed as the display image.

The image data storage section 20th stores data (image data) to generate various display images on the monitor 10th are displayed. The display image also includes a three-dimensional image. A three-dimensional shape is stored as image data for a three-dimensionally displayed image.

The line-of-sight detection device 30th captures a driver's point of view and line of sight. For this purpose, the line-of-sight detection device 30th a camera 31 on. 2nd shows an installation of the line-of-sight detection device 30th . According to the example of 2nd is the line-of-sight detection device 30th under the monitor 10th arranged. A detection area of the camera 31 that are in the line of sight detection device 30th is set to have a driver's head 4th includes. The installation of the line of sight detection device 30th is not on the in 2nd shown position limited. The line-of-sight detection device 30th can be in a position different from that in 2nd shown position to be installed when the driver head 4th can be recorded or recorded.

The line of sight detection device 30th analyzes one from the camera 31 captured image and captures the driver's eye position. More specifically, positions of a reference point and a movement point of the eye are detected. There is a known method that takes an inner corner of the eye as the reference point of the eye and an iris as the point of movement of the eye and detects a line of sight based on the positional relationship between the two. There is another known method that takes a corneal reflex as the reference point of the eye and a pupil as the moving point of the eye and detects a line of sight based on the positional relationship between the two.

The computing device 40 represents a computer with CPU, RAM, ROM, I / O (I / O) and a bus line connecting these components. A program executed by the CPU is stored in the ROM. The program only needs to be stored in a non-volatile, tangible storage medium that is not limited to the ROM as a specific storage medium. The program can, for example, be saved in a flash memory. The execution of a program by the CPU is comparable to the execution of a method corresponding to the program.

The computing device 40 enables the CPU to execute a program stored in the ROM and thus functions as an image data acquisition section 41 , a measurement value acquisition section 42 , a driver information acquisition section 43 and a playback section 44 as in 1 shown available. The one in the computing device 40 Function blocks contained can be provided in whole or in part as one or more ICs (as hardware). The one in the computing device 40 The functions contained can be provided in whole or in part by a combination of the execution of the software on the CPU and the hardware components.

The image data acquisition section 41 captures image data from the image data storage section 20th . 3rd shows one in a virtual room 50 placed display object 60 . The image data acquisition section 41 captures image data of the display object 60 .

According to the present embodiment, the monitor shows 10th Display images, ie images that are in virtual space 50 placed display objects 60 correspond and from a virtual Point of view. The display objects 60 are comparable to on the monitor 10th shown objects. In particular, the in 3rd displayed objects 60 a speedometer dial 61 , a rev counter dial 62 , A street 63 and a vehicle 64 . The vehicle 64 conceptually represents a vehicle in question (hereinafter referred to as a subject vehicle). The above is an example. The display object 60 may include objects different from those in 3rd are shown. The display object 60 may include various instruments such as a fuel gauge and a water temperature gauge, for example. The image data acquisition section 41 captures image data of the display objects 60 .

Illumination 65 and a camera 66 are also in virtual space 50 in 3rd placed. The lighting 65 represents the sunlight. The camera 66 represents the driver's focus and line of sight. The monitor 10th shows one from the camera 66 captured image as a display image. The one in virtual space 50 placed camera 66 indicates a virtual viewpoint.

The measured value acquisition section 42 captures a measured value by the display object 60 is shown. The example in 3rd includes the speedometer dial 61 and the rev counter dial 62 than the display objects 60 . The measured value acquisition section 42 therefore detects a vehicle speed and an engine speed as measured values. The measured values are recorded by sensors which record the measured values.

The driver information acquisition section 43 detects the driver's viewpoint position. The line-of-sight detection device 30th successively captures the driver's focus positions. Therefore, the driver information acquisition section acquires 43 successively the driver's viewpoint position from the line-of-sight detection device 30th . The viewpoint is an example of a viewpoint-related part.

The playback section 44 successively generates the display image based on that from the image data acquisition section 41 captured image data, that of the measured value acquisition section 42 successively acquired measured value and that from the driver information acquisition section 43 successively captured driver's point of view position. The playback section 44 shows the display image generated on the monitor 10th on. Below is one from the playback section 44 Process carried out using the in 4th shown flowchart described. In 4th leads the data acquisition section 42 the process in step S1 and the driver information acquisition section performs 43 the process in step S2 out. The playback section 44 leads the process from step S3 out.

The process in 4th takes place periodically after fulfillment of a condition for displaying the display image on the monitor 10th , such as turning on a vehicle power supply 2nd , during the image data acquisition section 41 captured the image data.

In step S1 the process captures a reading. In step S2 the process captures the driver's viewpoint position. In step S3 the process determines the position of a pointer of the display object 60 including the pointer from those in virtual space 50 placed display objects 60 based on the in step S1 recorded measured value.

In step S4 the process places the display object 60 that in step S3 reflects a certain pointer position in virtual space 50 . In the steps S5 and S6 the process allows the monitor 10th an image of the display object 60 that from the camera 66 is viewed from. The display object 60 is rotated based on an angle change in the driver's viewpoint position. The present embodiment classifies the display objects 60 in groups A and B . The group A uses a rotation angle that is smaller than a change angle θ at the driver's point of view. The group B uses an angle of rotation that is greater than the angle of change θ at the driver's point of view.

According to the present embodiment, the change angle θ between a reference line segment B and a line segment G , which is an intermediate position between the driver's two eyes, ie the center of the head 4th in the horizontal direction, with that for each display object 60 defined center of rotation C. connects, educated. The reference line segment B connects the center of rotation with the intermediate position between the driver's two eyes if the intermediate position between the driver's two eyes corresponds to a reference position. The reference position passes through the center of the steering and lies in a vertical plane which runs, for example, parallel to a forward-backward direction of the vehicle. The 8th and 10th show the line segment G and the reference line segment B .

The as a group A classified image data contain pointer positions from which information must be read. The need to read information describes the need to see a slight difference in shape positions or the need to spot a slight difference in shapes. The need to see a slight difference in shape positions will applied to the pointer position. The need to recognize a difference in shapes is applied to signs.

The as a group B classified image data enables a driver to eliminate the need to read the information or an increased requirement to read the information in a short time. The as a group A classified image data is comparable to motion suppression image data. The as a group B classified image data are comparable to movement promotion image data. According to the example in 3rd become image data of the speedometer dial 61 and the tachometer dial 62 as a group A classified and image data of the street 63 and the vehicle 64 as a group B classified.

In step S5 the process turns that through image data of the group A Display object shown 60 . The process rotates the display object 60 in a group A by an angle resulting from a multiplication of the change angle θ at the driver's viewpoint position and a positive coefficient less than 1 results. A specific value of the positive coefficient is determined on the basis of experiments taking into account a balance between ensuring visibility and improving realistic feeling or driveability.

5 shows the center of rotation C _A for the speedometer dial 61 and the rev counter dial 62 . The speedometer dial 61 and the rev counter dial 62 are on the same level. This level is hereinafter called the counter arrangement level 67 designated. The center of rotation C _A is in the meter arrangement level 67 contain. More specifically, the center of rotation is C _A in the middle between the speedometer dial 61 and the rev counter dial 62 at the meter arrangement level 67 positioned.

In step S6 the process turns that through image data of the group B Display object shown 60 . The process rotates the display object 60 in a group B by an angle resulting from a multiplication of the change angle θ at the driver's viewpoint position and a positive coefficient greater than 1 results. A specific value of the positive coefficient for determining the rotation angle for the group B is also determined experimentally, taking into account a balance between ensuring visibility and improving realistic feeling or driveability.

6 shows the center of rotation C _B for the street 63 and the vehicle 64 . The center of rotation C _B is in virtual space 50 positioned as far forward as possible. The position in front of the camera 66 goes from the camera 66 away in a shooting direction for the camera positioned at the 0 degree angle 66 . The center of rotation C _B for example at a vanishing point in virtual space 50 positioned. The street 63 as a long shape in depth is positioned towards the vanishing point.

7 shows the speedometer dial 61 and the rev counter dial 62 at the focal point position θ set to zero degrees. 7 also shows the reference line segment B . 7 shows a top view of the virtual space 50 viewed from above. The 8th to 10th are also illustrations to illustrate the virtual space 50 viewed from above. 7 shows a reference orientation of the speedometer dial 61 and the tachometer dial 62 . In 7 runs the counter arrangement level 67 orthogonal to the reference line segment B .

8th shows the angle of rotation θ2 for the speedometer dial 61 and the rev counter dial 62 when the angle θ at the driver's point of view on the angle θ1 will be changed. The angle of rotation θ2 for the speedometer dial 61 and the rev counter dial 62 results from the multiplication of the change angle θ1 at the driver's point of view and a coefficient less than 1 . Therefore, the size ratio is θ2 <θ1.

9 shows the street 63 and the vehicle 64 set to zero degrees at the viewpoint position. 9 shows a reference orientation of the speedometer dial 61 and the tachometer dial 62 . In 9 runs the road 63 parallel to the reference line segment B . 10th shows the angle of rotation θ3 for the street 63 and the vehicle 64 when the angle θ at the driver's point of view on the angle θ1 will be changed. The angle of rotation θ3 for the street 63 and the vehicle 64 results from a multiplication of the change angle θ1 at the driver's point of view and a coefficient greater than 1 . Hence the size ratio θ1 < θ3 .

In step S7 the process creates an image of the display object 60 that in the steps S5 and S6 rotated and from the position of the camera 66 is considered from. The generated image is provided as a display image. The position of the camera 66 becomes from the in step S2 detected driver's viewpoint position. The position of the lighting 65 corresponds to the position of the sun during image generation. It is necessary to establish a relationship in order to determine an angle of the sun from the time, the direction of travel and the current position around the To determine the position of the sun. The position of the lighting 65 is determined by the ratio, the current time, the direction of travel and the current position. For example, a GNSS receiver captures the current position. The direction of travel can be calculated from a trajectory for the current position.

From the position of the camera 66 seen from the street 63 and the vehicle 64 with the speedometer dial 61 or the rev counter dial 62 overlap. D .h., the display object 60 in a group A can deal with the display object 60 in a group B overlap. In this case, image data is grouped A generated display image always closer to the focal point than generated from image data in a group B generated display image.

The above process, if done, can change the driver's viewpoint position from the 0 degree direction. Then they become a group A belonging display picture and that to group B display image belonging to the corresponding display images, which are displayed at the driver's zero point position, rotated.

An angle of rotation for that from image data of the group B Display image is generated by multiplying the change angle θ at the driver's viewpoint position with a coefficient greater than 1 determined. An angle of rotation for that from image data of the group A Display image is generated by multiplying the change angle θ with a coefficient less than 1 determined. Therefore, the amount of rotation of the display image is in group B greater than the rotation amount of the display image in the group A . As a result, it is possible to give a realistic feeling to a driver, compared to a case where the rotation amount of all the display images is equal to the rotation amount of the display images in a group A is.

The amount of rotation of display images in a group A is smaller than the rotating amount of display images in group B . group A is classified to contain image data needed for reading necessary information such as e.g. B . Image data for the generation of the speedometer dial 61 and the tachometer dial 62 . Therefore, it is possible to reduce the difficulty in reading the necessary information.

In the present embodiment, the counter arrangement level is 67 configured to the center of rotation C _A for the speedometer dial 61 and the rev counter dial 62 to have that to the group A belong. The center of rotation C _B for the street 63 and the vehicle 64 going to the group B belong is before the center of rotation C _A in virtual space 50 positioned. The street 63 and the vehicle 64 cause the amount of movement on the monitor 10th is larger than in the case that the center of rotation C _B for the street 63 and the vehicle 64 at the meter arrangement level 67 lies. Therefore, the driver can be given a realistic feeling more effectively.

The present embodiment shows one of image data of the group A display image generated is always closer to the focal point than one from image data of the group B generated display image. Therefore, it is also possible to alleviate a difficulty in reading necessary information.

(Second embodiment)

A second embodiment is described below. An element identified by the same reference numeral as that used so far may be included in the description of the second embodiment or later, and in this case is the same as the element identified by the same reference number described in the previous embodiment unless otherwise stated. If only part of a configuration is described, the other parts of the configuration can correspond to the embodiment already described.

11 Fig. 12 shows a configuration of a vehicle display device 100 the second embodiment. The vehicle display device 100 is on the vehicle 2nd assembled. The vehicle display device 100 has an acceleration sensor 70 on. A computing device 140 has a vehicle acceleration detection section 145 and a playback section 144 different from the first embodiment.

The acceleration sensor 70 detects successive accelerations in the left-right direction of the vehicle 2nd . In addition, the acceleration sensor 70 Accelerations in the front-back direction and in the vertical direction of the vehicle 2nd capture.

The vehicle acceleration detection section 145 gradually records accelerations in the left-right direction on the vehicle 2nd occur from the accelerometer 70 . The playback section 144 differs from the playback section in that 44 the first embodiment that the playback section 144 an angle of rotation of the display object 60 based on one from the vehicle acceleration detection section 145 detected horizontal acceleration of the vehicle 2nd certainly.

Below is a process of the playback section 144 based on the in 12th shown flowchart described. The process in 12th takes place in place of the process 4th . In 12th leads the data acquisition section 42 the process in step S11 similar to step S1 out. The vehicle acceleration detection section 145 leads the process in step S12 out to a horizontal acceleration of the vehicle 2nd from the acceleration sensor 70 capture. The driver information acquisition section 43 leads the process in step S13 similar to step S2 out. The playback section 144 leads the process from step S14 out.

The process in steps S14 and S15 is similar to the process in the steps S3 and S4 from 4th . In step S16 the process turns that through image data of the group A Display object shown 60 . Unlike the first embodiment, in step S16 an angle of rotation of the group A belonging display object 60 as a change angle θ adopted at the driver's point of view. The center of rotation C _A is the same as the first embodiment.

Because the angle of rotation for the group A as determined above, the speedometer dial can 61 and the rev counter dial 62 be positioned directly in front of the driver's face, even when accelerating in the left-right direction of the vehicle 2nd the position of the driver's head 4th changes.

13 shows an example of the process in step S16 . The example in 13 assumes that a steering wheel 3rd is massively moved in a short time to achieve a large horizontal acceleration on the vehicle 2nd exercise, and the position of the driver's head 4th therefore moves massively to the right in the drawing.

The second embodiment can use the speedometer dial 61 and the rev counter dial 62 Position directly in front of the driver's face, even if the position of the driver's head changes 4th massively moved. Therefore, it is possible to impair the visibility of the speedometer dial 61 and the tachometer dial 62 to avoid.

In step S17 the process turns that through image data of the group B Display object shown 60 . The second embodiment determines an angle of rotation for the group B belonging display object 60 based on that in step S12 recorded acceleration amount. In particular, the relationship between the amount of acceleration in the left-right direction and the change angle θ experimentally determined at the driver's point of view. The one in step S12 detected acceleration and the above-mentioned ratio determine the change angle θ . The change angle θ becomes with a coefficient greater than 1 multiplied to determine the angle of rotation.

The angle of rotation is determined as above. The angle of rotation for the display object 60 in a group B is larger than an angle for positioning directly in front of the driver's face. Also in the second embodiment, the rotation amount of the display object 60 in a group B greater than the amount of rotation of the display object 60 in a group A .

14 shows an example of the process in step S17 . In contrast to 13 becomes the steering wheel 3rd but not massively moved. The rotation of the steering wheel 3rd therefore does not produce a large horizontal acceleration on the vehicle 2nd . This changes the position of the driver's head 4th not essential. However, the second embodiment finds the angle of rotation for the display object 60 in a group B by multiplying a coefficient greater than 1 with the change angle θ by the horizontal direction of the vehicle 2nd occurring acceleration is determined. Therefore, as in 14 shown the angle of rotation θ5 against the road 63 and the vehicle 64 larger than the change angle θ4 for the driver's face.

In step S18 the process creates an image of the display object 60 that in the steps S16 and S17 rotated and from the position of the camera 66 is considered from. The generated image is provided as a display image. The method similar to that in the first embodiment determines the position of the camera 66 and the position of the lighting 65 . As in the first embodiment, one becomes image data of the group A generated display image so that it is always closer to the viewpoint than one from image data of the group B generated display image. The generated display image is then sent to the monitor 10th given.

The second embodiment determines the angle of rotation for the display object 60 in a group B based on the horizontal acceleration of the vehicle 2nd . The angle of rotation for the display object 60 in a group B is larger than the angle of rotation for the display object 60 in a group A . Therefore, it is possible to have a realistic feeling and drivability for a driver compared to a case where the rotation amount of all the display images is equal to the rotation amount of the image data of the group A generated display images is to be guaranteed.

More specifically, the angle of rotation against the display object 60 in a group B by Multiplying a coefficient greater than 1 with the change angle θ determined by the direction of the left-right direction of the vehicle 2nd occurring acceleration is determined. As in 14 shown, the street move 63 and the vehicle 64 massive when the driver turns the steering wheel 3rd easily actuated. Therefore, the configuration can give the driver a realistic feeling.

The amount of rotation of the display images in a group A is smaller than the rotation amount of the display images in the group B . The display picture in group A is positioned at the angle of rotation just against the front of the driver's face, even if the position of the driver's head changes 4th changes. Therefore, it is possible to overcome the difficulty in reading the required information on the display image in groups A displayed, even if the position of the driver's head decreases 4th changes.

(First modification)

According to the above embodiments, the playback sections move 44 and 144 the display object 60 rotating. The display object 60 However, it cannot be rotated but moved linearly in the forward-backward direction.

If the display object 60 is moved linearly in the forward-backward direction, the amount of movement can be determined based on a viewpoint-related part of the driver. In this case, the display object 60 in virtual space 50 based on the amount of change in the position of the viewpoint-related part in the front-back direction of the vehicle. It is necessary to have the correspondence between the amount of a change in the position of the viewpoint-related part in the front-back direction of the vehicle and the amount of movement in the front-back direction of the display object 60 to be determined beforehand.

Will the display object 60 Moving linearly in the forward-backward direction, the amount of movement can be based on one on the vehicle 2nd occurring forward-backward acceleration can be determined. In this case, the display object 60 in virtual space 50 based on the on the vehicle 2nd occurring forward-backward acceleration moves back and forth. It is necessary to have correspondence between one on the vehicle 2nd occurring forward-backward acceleration and the amount of movement in the forward-backward direction of the display object 60 to determine in advance.

(Second modification)

The first embodiment determines the rotation angle based on the driver's viewpoint position. However, the angle of rotation can also be based on the position of the head 4th instead of the viewpoint position. That is because the head 4th moved along with the focus. The position of the head 4th is an example of the viewpoint-related part.

(Third modification)

The angle of rotation can be determined using the line of sight direction instead of the viewpoint position. As above, the reference point and the movement point of the eye are detected to detect the line of sight direction. Therefore, the viewpoint position is also detected when the line of sight direction is used to detect the rotation angle. If the line of sight is used, the rotation angle for the display object 60 determined based on an angle change amount of the line of sight.

(Fourth modification)

The above embodiments classify the display object 60 in a group A and group B . In addition, a group C. be formed. group C. contains an object that does not move despite a change in the position of the viewpoint-related part or a change in the acceleration occurring on the vehicle.

group C. can contain, for example, an image to provide the driver with information on the monitor 10th to provide based on a state of turning the light on and off. In particular, the group C. contain an indicator such as a seat belt reminder. In other ways, the group C. contain an image on the corners or outer edges of the monitor 10th is shown. Originally, these positions provide the driver with less visibility and, when moved, adversely affect visibility. The positions unsuccessfully give the driver a realistic feeling when they are moved.

(Fifth modification)

The first embodiment can use the coefficient 0 with the change angle θ at the driver's viewpoint position with respect to the display object 60 in a group A multiply. D .h., in the first embodiment, the group A not be moved even if the position of the viewpoint-related part changes. The second embodiment can also change the amount of movement of the group A regardless of any acceleration occurring on the vehicle 0 put.

(Sixth modification)

The images displayed on the vehicle display device may include instruments such as the speedometer dial 61 and the rev counter dial 62 also not included. The vehicle display device can be embodied, for example, as a navigation system.

(Seventh modification)

A yaw rate acceleration can be considered a horizontal acceleration of the vehicle 2nd be recorded. The yaw angle can be detected, for example, by differentiating a yaw rate detected by a yaw rate sensor.

(Eighth modification)

The above embodiments use the road 63 than the display object 60 the group B . The street 63 is shaped deeper or longer in the forward-backward direction than the display object 60 the group A . The deeply shaped display object 60 can effectively convey the realistic feeling or driveability to the driver by turning the center of rotation C _B placed ahead. The deeply shaped display object 60 is not on the street 63 limited. The display object 60 can include a river, for example.

(Ninth modification)

The second embodiment may use a method similar to the first embodiment to determine one of the rotation angle for the group A and the angle of rotation for the group B to determine.

(Tenth modification)

The first and the second embodiment form the center of rotation C _A to the group A at the meter arrangement level 67 , ie the level that the speedometer clock face 61 and the rev counter dial 62 than the display objects 60 in a group A contains rotating to move. The center of rotation CA. can, however, in front of the display object 60 in a group A to be placed. D .H. the display object 60 in a group A can continue from the center of rotation C _A be placed away.

15 shows an example where the center of rotation C _A between the driver and the display object 60 is placed. According to the example in 15 becomes the display object 60 in a group A around the angle θ6 around C _A rotated as the center of rotation when the change angle θ at the driver's point of view θ6 is. The display object 60 in a group A is about the angle θ7 around C _A rotated as the center of rotation when the change angle θ at the driver's point of view θ7 is. Therefore, in the example of 15 , the display object 60 positioned directly in front of the driver's face, even if the position of the driver's head changes 4th changes.

If the display object 60 in a group A around the angle θ6 or θ7 is rotated, corresponds to the rotating amount of the display object 60 in a group B an angle resulting from a multiplication of the angle θ6 or θ7 with a coefficient greater than 1 results. Same as the center of rotation C _A for the group A can be the center of rotation C _B for the group B also between the driver and the display object 60 in a group B to be placed.

(Eleventh modification)

The first embodiment moves group A and group B in the direction of change of the viewpoint-related part. The group B can, however, be moved in a direction opposite to the change direction of the viewpoint-related part. 16 shows an example of the movement of the display object 60 in a direction opposite to the direction of change of the driver's viewpoint. The display object 60 is rotating around C _B moved as the center of rotation. In 16 becomes the display object 60 than to the group B properly accepted.

In the eleventh modification, the amount of movement of a display image corresponds to the amount of change of an angle between the line segment G similar to the first embodiment and that different from the display object 60 to the center of rotation C _B extending line segment H . A dashed line illustrates a state before the movement. In this state they form the line segment G and the line segment H an angle equal to 0 . A solid line illustrates a state after the head has moved. In this state they form the line segment G and the line segment H an angle of θ7 + θ8. Therefore, the change amount of the angle is also equal to θ7 + θ8.

The eleventh modification can change the amount of rotation of the display object 60 in a group A using the calculation method previously described in the embodiments and modifications. The eleventh modification can change the amount of rotation of the display object 60 in a group A by multiplying a positive coefficient less than 1 with the change angle θ7 determine at the driver's point of view. It is also possible to move the display object 60 in a group A regardless of an angle change at the driver's point of view. In any case, the amount of rotation of a display image is in group B greater than the amount of rotation of a display image in a group A .

(Twelfth modification)

The eleventh modification describes that the display object 60 in a group B is rotated in a direction opposite to the change direction of the viewpoint-related part. In the second embodiment, it is described that the display object 60 in a group B due to the acceleration in the left-right direction of the vehicle 2nd is rotated. Acceleration in left-right direction when on the vehicle 2nd occurs, changes the position of the viewpoint-related part. Therefore, a display object of the group B in a direction opposite to the acceleration in the left-right direction of the vehicle 2nd be moved. 16 described above can also be used as an example of the movement of the display object 60 the group B in a direction opposite to the acceleration in the left-right direction of the vehicle 2nd be considered.

According to the twelfth modification, the amount of movement of the display image is equal to the amount of change in angle between the line segment G and the line segment H . The twelfth modification can change the amount of rotation of the display object 60 in a group A using the calculation method described in the second embodiment and the modifications. In the twelfth change, for example, the amount of rotation of the display object 60 in a group A on the acceleration in the left-right direction of the vehicle 2nd aligned and set less than or equal to a driver angle change angle resulting from the acceleration in the left-right direction of the vehicle 2nd can be estimated. It is also possible to move the display object 60 in a group A regardless of a horizontal acceleration of the vehicle 2nd to prevent. In any case, the amount of rotation of a display image is in a group B greater than the amount of rotation of a display image in a group A .

(Thirteenth modification)

Above are the rotating movement and the linear movement in the front-back direction as the movement modes of the display object 60 described. It is also possible to use a horizontal sliding movement instead of the rotating movement as the mode for moving the display object 60 to use. As in the 15 and 16 shown, the display object moves 60 seen horizontally from the driver when the center of rotation C. in front of or behind the display object 60 positioned from the driver's perspective. Therefore, the horizontal sliding movement can replace the rotating movement.

(Fourteenth modification)

The monitor 10th viewing drivers, realistic images can be provided since the display images are grouped A and B categorized and the display positions of the display images are moved depending on the amount of change in positions of the viewpoint-related part. However, there may be a driver who does not prefer realistic images. Therefore, it may be advantageous to allow the user to choose whether to perform the process that moves the display images depending on the amount of change in positions of the viewpoint-related part.

Users can have different preferences for the amount of movement of the groups A and B to have. Therefore, it may be advantageous to allow a user to change the amount of movement of the groups A and B corresponding to the amount of a change in positions of the viewpoint-related part on a group basis or in the groups A and B to configure together.

(Third embodiment)

A third embodiment of the present disclosure will be described below with reference to the accompanying drawings. 17th Fig. 12 is an illustration showing a schematic configuration of a vehicle display system 300 of the present embodiment. As in 17th shown, the vehicle display system 300 a display control device 201 , a monitor 202 , an occupant camera 203 and a vehicle ECU 204 on. ECU stands for Electronic Control Unit.

The occupant camera 203 and the vehicle ECU 204 are each with the display control device 201 connected in order to be able to communicate with one another via a communication network set up in the vehicle (hereinafter referred to as “vehicle network”). The display 202 and the display control device 201 are connected so that they can communicate with each other via the vehicle network or a dedicated line for video signals.

Below is the term "subject vehicle" for a vehicle display system 300 vehicle used. The present embodiment assumes that the subject vehicle is a vehicle that uses an engine as a drive source. In addition, the subject vehicle can only use one motor as a drive source (as a so-called electric vehicle) or use an engine and an internal combustion engine as the drive source (as a so-called hybrid vehicle).

Schematically, the display control device uses 201 a three-dimensional computer graphic to display an image of an analog instrument (hereinafter referred to as an analog measuring device (counter)), which shows information about a driving control of the vehicle (hereinafter referred to as vehicle information), and displays the image on the monitor 202 on. The instrument displaying the vehicle information includes, for example, a tachometer indicating the engine speed and a speedometer indicating the vehicle speed. The analog measuring device shows a numerical value for the state amount (such as the vehicle speed), which is displayed as actual units with the aid of a pointer and a scale area. The display control device 201 shows an instrument image that simulates the analog measuring device mentioned above.

The display 202 shows one of the display control device 201 entered image. According to the present embodiment, the monitor is 202 , as in 18th shown as an example, as a monitor (so-called counter monitor) 221 in the area A1 an instrument panel arranged in front of the driver's seat. The display 202 is a full color display and can be embodied as a liquid crystal display, organic EL display or plasma display.

According to another mode, the monitor can 202 be mounted in a position different from the above position. The display 202 can be used as a monitor (so-called central monitor) 222 for example at the top of a middle section (hereinafter referred to as the middle section) A2 be installed in the vehicle width direction of the dashboard. The display 202 can basically display a navigation screen and can next to a steering column cover in the middle A2 be placed. The display 202 can be provided as a head-up display that displays a virtual image on a portion of a windshield in front of the driver's seat.

The display control device 201 displays the above instrument image, such as B. a tachometer image 206 that shows the current engine speed and a speedometer image 207 , which shows the current vehicle speed, as in 19th shown. The tachometer image 206 simulates an analog tachometer that represents the current engine speed by rotating a pointer over an approximately circular scale surface that is provided with scales and numerical values that correspond to the engine speed detected by a sensor. The speedometer image 207 simulates an analog speedometer that represents the current vehicle speed by rotating a pointer over an approximately circular scale surface that is arcuately provided with scales and numerical values corresponding to the vehicle speed detected by a vehicle speed sensor.

The instrument image corresponds to vehicle information, such as the engine speed or the vehicle speed. The instrument image is positioned on a predetermined layout and on the monitor 202 displayed. An image that finally appears on the monitor 202 is displayed, for the sake of simplicity it is also referred to as a counter unit image.

Below, the speedometer and the tachometer are chosen as illustrative instruments to be used by the display control device 201 to be displayed. The following describes a case where the monitor 202 Displays images including these two instrument images as the final counter unit image. In particular, below is the mode for displaying the counter unit image, that is, the image including both the tachometer image 206 as well as the speedometer image 207 described.

It may be advantageous to have types, combinations or the number of instruments used by the display control device 201 is to be displayed, designed in a suitable manner. The types of instruments to be displayed can be changed dynamically depending on conditions of the vehicle, such as while driving. Only the tachometer or the speedometer can be displayed as the instrument to be displayed. It may be advantageous to display an image with other types of vehicle information (such as the shift positions). The instruments to be displayed may include a fuel gauge that shows the remaining fuel using a pointer and a scale, or a water temperature gauge that shows the temperature of the cooling water for cooling the engine. The instrument image can be displayed as an image simulating the fuel gauge or the water temperature gauge. The subject vehicle can be, for example, an electric vehicle or a hybrid vehicle that uses an engine (internal combustion engine) as the drive source. In such a case, the instruments to be displayed may include a battery indicator that mainly indicates the remaining battery level by a pointer.

The display control device 201 is configured as a computer. The display control device 201 includes a CPU 211 to perform various types of arithmetic processing, a RAM 212 , a flash memory 213 , an I / O (I / O) 214 , a 3D model storage section 215 and a bus line for connecting these components.

The CPU 211 is configured to perform various types of computing processing and can be embodied, for example, by a microprocessor. The display control device 201 can the CPU 211 replace with an MPU or GPU. The RAM 212 is intended as the volatile memory. The flash memory 213 is intended as the non-volatile memory.

The flash memory 213 Mainly stores a program (hereinafter referred to as a display control process) that enables a normal computer as the display control device 201 to work. The above-mentioned display control process only needs to be stored in a tangible storage medium (in a non-volatile tangible storage medium). The execution of the display control process in the CPU 211 corresponds to executing a procedure according to the display control process. The CPU 211 executes the display control process and the display control device 201 thus provides various functions. Various functions in the display control device 201 are described below.

The I / O 214 is provided as an interface to the display control device 201 enables data from an external device (e.g. the vehicle ECU 204 ) enter or output. The I / O 214 may mainly be embodied by an IC, a digital circuit element or an analog circuit element.

The 3D model storage section 215 is provided as a storage device that stores data used to display an instrument image. The 3D model storage section 215 is embodied using a non-volatile storage medium. The data used to display an instrument image is a three-dimensional form on a sub-basis, around a 3D model of the instrument, such as the tachometer or the speedometer on the monitor 202 , to create. The data representing a three-dimensional shape also describe data that represent a three-dimensional model (3D model).

More specifically, as in 20th shown, the 3D model storage section stores 215 a base plate object 271 , several scale objects 272 and a pointer object 273 as stereoscopic data for each part of the tachometer model Md1 as a 3D model of the tachometer.

The base plate object 271 provides data representing a stereoscopic model of a base plate, comparable to a plate-shaped element which represents an external shape of the tachometer scale surface. In other words, the base plate object 271 is provided as an element that provides a background corresponding to an area in which the pointer rotates. The base plate object 271 is schematically shaped so that scales are punched into the scale surface. A hole (hereinafter called a scale hole) 911 corresponding to the scale is in the base plate object 271 punched. A character (e.g. an integer from 0 to 8) according to the scale hole 911 is near the scale hole 911 attached.

The present embodiment provides an example in which the tachometer has nine scales corresponding to the integers 0 to 8th has and accordingly nine scale holes 911 corresponding to the nine numeric characters 0 to 8th having. The tachometer shows an engine speed by multiplying a numerical value on the scale by 1000. D .h., the engine speed is described by nx 1000 [U / min or 1 / min or rpm], where n is an arbitrary numerical value (n = 0 to 8), which is assigned to each scale.

In this example, the base plate object contains 271 integral a character that describes the numerical value according to each scale as a surface design of the base plate object 271 , but is not limited to this. The 3D model storage section 215 can a character representing the numerical value as an object (hereinafter referred to as a drawing object) independent of the base plate object 271 to save.

The scale object 272 is intended as a stereoscopic model of the tachometer scale. The present embodiment shows an example of using nine scale objects 272 according to the numeric characters 0 to 8th . Any scale object 272 with the scale hole 911 of the base plate object 271 combined into a stereoscopic model (or a scale surface object) for the scale surface.

The pointer object 273 provides data representing the stereoscopic model of a pointer element. The pointer object 273 contains a pointer body section 931 as a pointer body and a rotation axis section 932 that with the base plate object 271 is connected and an axis of rotation of the pointer body portion 931 forms.

Above are the stereoscopic data for each part of the tachometer model Md1 described in more detail. The same applies to the stereoscopic data for each part of the speedometer model Md2 as a 3D model of the speedometer. Similar reference numerals for parts of the speedometer model are given below for simplicity Md2 and parts of the tachometer model Md1 used. D .h., the 3D model storage section 215 saves the base plate object 271 , several of the scale objects 272 and the pointer object 273 as stereoscopic data for each part of the speedometer model Md2 .

Multiple stereoscopic data samples can be provided for each instrument. For example, the stereoscopic data patterns can be selectively used based on screen layouts, vehicle conditions, or user options. The 3D model storage section also stores 215 as well as data (or design skin data) representing design skins to change colors or textures for each part of the instruments.

The occupant camera 203 is installed to detect the face of an occupant sitting in a driver's seat (hereinafter referred to as driver). The occupant camera 203 is placed, for example, in such a way that the center (so-called optical axis) of a recording direction is aligned with the presence of eyelids for the subject vehicle. The eyelids provide a predetermined region based on an eye area that statistically represents the distribution of driver's eye points (see JISD0021: 1997 for details). The occupant camera 203 can be attached so that it captures the driver's facial area in an appropriately designed position, such as on a steering column cover, on a part of an instrument panel opposite the driver's seat or near an interior rear-view mirror.

The occupant camera 203 is embodied by a near infrared light source, a near infrared camera and a control unit for controlling the components. The occupant camera 203 detects the position of the driver's head or the direction of the driver's face by applying a known image recognition process to the image captured by the near infrared camera. The present embodiment also successively detects the eye position. The occupant camera 203 gives successive line of sight origin point information to the display control device 201 out. The line-of-sight origin point information mainly represents the driver's head position, face orientation, and eye position specified from the captured image. The position of the head or eye can be expressed in coordinates of a three-dimensional coordinate system provided for the vehicle. The driver's head position or eye position serves as information indicating the direction in which the driver's eye is from the monitor 202 viewed from. The driver's head position or eye position is comparable to information that has a point of origin (or starting point) on the monitor 202 directional line of sight.

The occupant camera 203 can provide a detection area that covers not only the driver's face but also the upper body. The occupant camera 203 is not limited to an infrared camera and may also be available as an optical camera. The occupant camera 203 can be embodied using known imaging devices such as CCD and CMOS. The occupant camera 203 corresponds to a line-of-sight origin detection device. The line of sight origin detection device can estimate a position of the driver's head by transmitting and receiving search waves such as ultrasonic waves or millimeter waves.

The vehicle ECU 204 captures information (vehicle information) about vehicle conditions that is required for driving manipulations from various sensors (hereinafter referred to as vehicle-side sensors) 5 which are mounted on the subject vehicle.

Corresponding information that belongs to the vehicle information mentioned above is also referred to as element information. The vehicle ECU 204 outputs the above various types of vehicle information to the display control device in succession 201 out.

(Functions of the Display Control Device 201)

The following are the functions of the display control device 201 with reference to 21 described. The display control device 201 provides functions according to different function blocks as in 21 shown ready by the CPU 211 allows to execute the above display control process. The display control device 201 includes the functional blocks such as a vehicle information acquisition section F1 , a modeling section F2 , a line-of-sight origin detection section F3 and a playback section F4 .

The in the display control device 201 Function blocks contained can be embodied in whole or in part as hardware. The mode of the embodiment using the hardware includes a mode of the embodiment using one or more ICs. The in the display control device 201 Function blocks contained can be wholly or partly by a combination of the execution of the software in the CPU 211 and the hardware elements.

The vehicle information acquisition section F1 acquires various types of vehicle information from the vehicle ECU 204 and successively passes the vehicle information to the modeling section F2 . The vehicle information acquisition section F1 For example, successively records the current vehicle speed or engine speed and passes this on to the modeling section F2 .

The modeling section F2 represents a three-dimensional shape of each instrument to be displayed in virtual 3D space based on 3D shape data stored in the 3D model storage section 215 are saved. The modeling section F2 generates the tachometer model Md1 and the speedometer model Md2 . The modeling section F2 corresponds to a stereoscopic instrument model generation section. For the sake of simplicity, a modeling process refers to a process that 3D models for various instruments based on in the 3D model storage section 215 saved 3D shape data generated. The stereoscopic model for each instrument is embodied by defining 3D coordinates corresponding to corner points for each part and a connection between them.

The modeling section creates schematically F2 a scale surface object by the scale object 272 in each for the base plate object 271 provided scale hole 911 is arranged (in particular inserted or inserted). The axis of rotation section 932 is arranged so that its bottom is in contact with a certain position (such as the center) of the dial object, thereby creating a 3D model (hereinafter referred to as a stereoscopic instrument model) for the instrument to be displayed.

As in 22 is shown, the pointer object 273 combined with the 3D model of the instrument and rotates (or moves) within a plane around the separation distance α separate from the surface of the base plate object 271 . The one in the pointer object 273 included axis of rotation section 932 ensures the separation distance α . A specific value of the separation distance α can be designed in a suitable manner. In the present example, the separation distance α assumed to be 4 mm. The separation distance α can be set to 2 mm, 10 mm or other values. The axis Ax in 22 represents the axis of rotation of the pointer object 273 represents.

The scale object 272 is usually placed so that its tip matches the surface of the base plate object 271 coincides. A projection amount setting section F22 (described below) determines the position of the scale object 272 with respect to the surface (hereinafter referred to as the base plate surface) of the base plate object 271 , in particular the amount of the lead (hereinafter referred to as the lead amount) β that is applicable to the tip of the scale object that protrudes from the base plate surface.

The mode for setting the amount of projection β on 0 corresponds to a mode for arranging the scale object 272 such that its tip coincides with the base plate surface. The base plate surface is one of two surfaces of the base plate object 271 and enables the placement of the pointer object 273 . The collapse in this example is not limited to a complete collapse. The collapse includes a mode in which the tip of the scale object 272 protrudes negligibly from the base plate surface.

The modeling section F2 includes a pointer position determination section F21 and a protrusion amount setting section F22 as sub-functions for executing the above-mentioned modeling process. The pointer position determination section F21 determines the position of the pointer relative to the base plate object 271 as a stereoscopic model of the instrument to be displayed. Specifically, the pointer position determination section determines F21 the position (more precisely an angle of rotation) of the Pointer object 273 towards the base plate object 271 of the tachometer based on one from the vehicle information acquisition section F1 supplied engine speed so that the pointer object 273 displays the current engine speed. The pointer position determination section F21 determines the position of the pointer object 273 towards the base plate object 271 of the speedometer based on one from the vehicle information acquisition section F1 delivered vehicle speed so that the pointer object 273 shows the current vehicle speed. The through the pointer position determination section F21 specific position of the pointer object 273 is comparable to the position that indicates the current state (in particular a numerical value) of the vehicle information to be displayed.

The projection amount setting section F22 determines the amount of advance β every scale object 272 based on that by the pointer position determining section F21 certain pointer position. The amount of advance β from one of the scale objects 272 indicates the amount of protrusion for the tip of the scale object 272 applicable from the surface (base plate surface) of the base plate object 271 protrudes.

The projection amount setting section F22 determines the amount of advance β in accordance with the display value distance D as a difference (conceptually, a distance) between one with each scale object 272 linked numerical value and a numerical value indicated by the pointer. In particular, the amount of advance β for the scale object 272 associated with a value that is approximately that of the pointer object 273 displayed value corresponds to a high value. In other words, the scale object 72 at a position close to that through the pointer 73 displayed position becomes a lead amount β awarded to a relatively larger value than that for the scale object 72 at a position away from that by the pointer 73 displayed position is set. The amount of advance β can be dynamic to a range of values greater or equal 0 and less than or equal to α be set. For example, if the tachometer pointer says “ 3rd “, The display value distance applies D who on 1 is set (strictly speaking, 1 x 1000 rpm) for the scale objects 272 , with " 2nd " and " 4th “Are linked on the scale surface. When the tachometer pointer “ 3rd “, The display value distance applies D set to two (strictly speaking 2 x 1000 rpm) for the scale objects 272 , with " 1 " and " 5 “Are linked on the scale surface.

As in a solid line in 23 shown, the protrusion amount setting section F22 the amount of the advance β equal to a direct function (or linear) with respect to the display value distance D reduce. As in a dashed line 23 shown, the protrusion amount setting section F22 the amount of the advance β equal to a curved line with respect to the display value distance D reduce. In 23 the vertical axis represents the amount of protrusion β and the horizontal axis the display value distance D The value d plotted on the horizontal axis represents a numerical value corresponding to a scale division. This is the numerical value 1000 [Rpm] assigned, for example, to a scale division of the tachometer according to the present embodiment. The numerical value 20th [km / h] is assigned to a scale division of the speedometer according to the present embodiment.

The example of 23 , shown by the solid and dashed lines, provides a control mode in which the amount of protrusion β on α as the maximum value for the scale object 272 is set with the on 0 set display value distance D is provided, ie the scale object 272 corresponding to that through the pointer object 273 displayed numerical value. Also poses 23 a control mode in which the amount of projection β on 0 as the lowest value for the scale object 272 is set according to a numerical value that corresponds to the display value distance D can make four or more scales.

The maximum amount of the lead amount β doesn't have to α can be set, for example, to 0 , 7α , 0 , 5α or 0 , 3α can be set. As described in more detail below, a value is suppressed larger 0 a position error (position offset) between the pointer and the scale in the display image, which can improve the visibility of the vehicle information. The lowest value of the amount of the lead β doesn't have to 0 can be set, but can for example 0 , 1α , 0 , 3α or 0 , 5α be set.

The modeling section F2 places the pointer object 273 in the middle of the base plate object 271 to one by the pointer position determination section F21 display certain angle of rotation. In addition, the modeling section constructs F2 a stereoscopic instrument model by each scale object 272 is placed so that it is through the projection amount setting section F22 certain amount of projection β protrudes from the base plate surface. The configuration for arranging the pointer object 273 at one by the pointer position determination section F21 specific position is comparable to a configuration for arranging the pointer object 273 at a position indicating a particular condition.

The modeling section creates when generating 3D models for all instruments to be displayed F2 a counter unit object 275 , including the 3D models arranged on a plate-shaped object (hereinafter referred to as a base object) 74 based on a predetermined layout. The 3D models for everyone Instruments to be displayed include the tachometer model Md1 as a 3D model of the tachometer and the speedometer model Md2 as a 3D model of the speed meter.

The base object 274 serves as a base for attaching the stereoscopic instrument model and adjusts for example with the display area of the monitor 202 comparable element in virtual 3D space. The base object 274 may contain an area where no stereoscopic instrument model is placed. This area serves as the background for the counter unit image. That from the modeling section F2 generated counter unit object 275 to the playback section F4 given.

As another mode, the base object 274 by a certain distance (such as a length of 2 cm) from the display surface of the monitor 202 be moved to the front (front) in virtual 3D space. The front or front describes a direction that is orthogonal to the display surface of the monitor 202 runs and from a vehicle interior to the monitor 202 Is accepted. The back of the monitor 202 describes a direction opposite to the forward direction and therefore from the monitor 202 to the vehicle interior is accepted.

As above, the base object 274 by a certain distance from the display area of the monitor 202 moved forward in virtual 3D space. According to this configuration, the edge of the base object can 274 Upright with an object (wall surface object) as the side wall that is aligned with the edge of the display area of the monitor 202 is connected to be provided. The wall surface object and the base object 274 are combined into a box-shaped object that represents a housing that contains the stereoscopic instrument model to be viewed from the vehicle interior. The display area of the monitor 202 is comparable to an opening in the housing.

The line of sight origin detection section F3 captures the line of sight origin point information from the occupant camera 203 . The line of sight origin detection section F3 captures the line-of-sight origin information that may represent the driver's head position or, more specifically, the eye position. In the following, the detection of information (eye position information) describing the eye position is assumed to be the line of sight origin point information. The through the line of sight origin detection section F3 obtained eye position information is sent to the reproducing section F4 given.

The playback section F4 specifies the position and the direction corresponding to the existence of the driver's eye in the virtual 3D space based on that from the line-of-sight origin detection section F3 provided eye position information. As in 24th shown, the specified position of the driver's eye in the virtual 3D space is comparable to a position of the driver's eye relative to the counter unit object 275 . In 24th poses a camera 208 the driver's point of view.

The playback section F4 gives an image of the counter unit object 275 from the driver's point of view again. The reproduced image represents the instrument at a specified or specific position in the virtual 3D space, that of the monitor 202 is provided in a mode currently visible to the driver. 24th shows the mode in which the driver's focus is in front of the meter unit object 275 exists. The mode in 24th places the tachometer model Md1 right and the speedometer model Md2 seen on the left of the driver on the display screen. The right and left positions can be interchangeable.

(Display control process)

Below is the display control process with reference to that in FIG 25th shown flowchart described. The display control process is to be carried out periodically (for example every 100 milliseconds) when the vehicle's ignition energy supply is switched on.

In step S101 reads the modeling section F2 stereoscopic data for parts of the counter to be displayed from the 3D model storage section 215 . According to the present embodiment, the process reads out stereoscopic data for parts of the tachometer and the speedometer and then proceeds to step S102 Ahead.

In step S102 detects the vehicle information acquisition section F1 the vehicle information and proceeds to step S103 Ahead. In step S103 the process determines the pointer position in each stereoscopic instrument model and the amount of protrusion β of the scale object 272 . D That is, the process determines the pointer position in each stereoscopic instrument model based on that from the pointer position determination section F21 in step S102 recorded vehicle information (such as the engine speed or the vehicle speed).

The projection amount setting section F22 determines the amount of advance β each scale object according to the pointer position. For example, the process calculates the display value gap D for every scale object 272 based on the pointer position and represents the amount of projection β according to the display value distance D a. That with reference to 23 The method described is applied to the amount of the advance β according to the display value distance D to determine. The process determines the amount of advance β the scale object according to the pointer position based on each instrument to be displayed. The process determines the amount of advance β for every scale object 272 and then goes to step S104 Ahead.

In step S104 creates the modeling section F2 a stereoscopic instrument model for each instrument to be displayed based on the one in step S103 specific pointer position and that in step S103 certain amount of advance β . D .h., it will be the tachometer model Md1 and the speedometer model Md2 generated. The process thus creates 3D models of the instruments, including the scale, which protrudes from the base plate in the direction of the pointer by the amount corresponding to the pointer position. The process creates the counter unit object 275 by the tachometer model Md1 and the speedometer model Md2 on the base object 274 be placed, whereupon the process to step S105 progresses.

In step S105 specifies the line-of-sight origin detection section F3 the driver's eye position (hereinafter referred to as the viewpoint) with respect to the counter unit object 275 based on that from the occupant camera 203 provided line of sight origin point information, whereupon the process to step S105 progresses. As above, the eye position can be replaced by the head position.

In step S106 gives the playback section F4 an image of the counter unit object 275 from the driver's point of view again, the image shows on the monitor 202 on and ends the process flow. The process shows the image of the counter unit object 275 viewed from the front when the driver's focus is in front of the meter unit object 275 located. The process shows the image of the counter unit object 275 viewed from below when the driver's point of view is below the front direction for the meter unit object 275 located.

The front direction for the counter unit object 275 indicates a direction orthogonal through the center of the base object 274 runs and from the base object 274 to the vehicle interior is accepted. The front direction for the counter unit object 275 is comparable to the front direction for the display area of the monitor 202 . Below are objects included in the element names among the elements that form a stereoscopic instrument model that is on the monitor 202 is displayed, omitted. For example, the base plate object 271 as a display image on the monitor 202 referred to as the base plate. The scale object 272 as a display image on the monitor 202 is simply called the scale. The same applies to the other elements including the pointer object 273 .

A comparison configuration provides a stereoscopic instrument model that is configured in such a way that the pointer moves while maintaining a predetermined separation distance α rotates from the scale surface including the scales arranged at the same height as the base plate. Effects of the present embodiment compared to a display control device that displays an image of the stereoscopic model viewed from the driver are explained below. The comparison configuration is similar to a conventional configuration as described in Patent Document 1 and is similar to a configuration that prevents the scale from protruding from the base plate.

As in picture 26A shown, a tachometer according to the above-mentioned comparison configuration has a pointer that indicates 0 rpm. If the driver's point of view is below the front direction for the monitor, the pointer becomes, as in, due to the gap between the scale surface and the pointer 27A shown, displayed at a position shifted upwards from the scale "0".

In the same way, according to the comparison configuration, the tachometer points as in 26B shown, the pointer that shows 3 x 1000 rpm. If the driver's point of view is below the front direction for the monitor, the pointer becomes, as in, due to the gap between the scale surface and the pointer 27B shown, shown at a position shifted from the scale for 3 x 1000 rpm to the top right.

The visual shift (on the display screen) between the pointer and the scale helps to give the driver a three-dimensional appearance (more specifically, a sense of depth) of the instrument image. However, the driver can hardly see the exact numerical value indicated by the pointer. The driver can see the pointer that is near 0 or 3rd indicates, but hardly the more precise numerical value.

According to the present embodiment, however, the scale near the pointer is shown so that it protrudes from the base plate. As in 26A shown, the tachometer has the hand indicating 0 rpm. In this situation, the instrument picture, as in 28A shown on the Rendered the basis of a 3D model that the with 0 linked scale protrudes near the pointer. As in 26B shown, the tachometer has the pointer that shows 3000 rpm. In this situation, the instrument picture, as in 28B shown, reproduced on the basis of a 3D model, which allows the scale linked to 3000 rpm to protrude near the pointer.

The above configuration shows the scale near the pointer as in the 28A and 28B shown, protruding stereoscopically or outstanding, even if the driver's point of view is below the front direction for the monitor. This display mode suppresses a distance in depth between the pointer and the scale near the pointer. The driver can easily see the exact scale (or the exact numerical value) indicated by the pointer.

The configuration of the present embodiment can display a three-dimensional instrument image while preventing the visibility of the vehicle information from being affected by a separation between the base plate and the pointer. The effect of the present embodiment is described above using the example of a display of the tachometer. The same applies to the other types of instruments (such as speedometer and water temperature display).

The above-mentioned embodiment maximizes the amount of protrusion β for the scale object closest to the pointer 272 and decreases the heights of the other scale objects 272 gradually proportional to the distance from the pointer. According to this configuration, the amount of protrusion varies β every scale object 272 with a rotation of the pointer. The realistic feeling that is given to the driver can be improved because of the amount of advance β the scales vary dynamically with the pointer positions. This can increase the economic value.

According to the example of the curve in 23 sets the rule for determining the amount of the advance β the amount of projection according to the pointer position β about on α when the display value distance D In the range of 0 up to 0.5 d. This is because the curve is shaped so that it points at you 0 set display value distance D and an approximate amount of projection β to α according to the display value distance D In the range of 0 increases to 0.5 d. According to this configuration, when the pointer object 273 indicates an intermediate numerical value between two scales, the two scale objects 272 displayed so that they protrude at the same height as the pointer. The two scale objects 272 are displayed in a mode that allows the two scales that place the pointer between them to protrude to the same height as the pointer. In this display mode, the driver can easily see that the pointer shows an intermediate numerical value between the two scales. The scale object 272 protrudes to the plane in which the pointer object is 273 rotates when the scale object 272 is positioned so that it is from the pointer object 273 (more precisely from the tip) is less than or equal to half the scale interval. The driver can thus easily recognize the numerical value indicated by the pointer.

As above, the configuration of the present embodiment can prevent the visibility of the vehicle information by the separation distance α between base plate and pointer is impaired. It is possible to limit the separation distance α to loosen to ensure the visibility of vehicle information. Hence the distance α between the base plate and the pointer to a value that is greater than an actual instrument. An increase in the separation distance α between the base plate and the pointer can enhance the sense of depth provided by the stereoscopic instrument model. The present embodiment can the separation distance α Enlarge between the base plate and the pointer and display an instrument image that offers a more attractive three-dimensional appearance.

The above operations of the display control device 201 are applicable when the instrument image shows certain vehicle information. The instrument image does not necessarily have to be used as the display mode of the vehicle information, even if the instrument image can display the vehicle information (such as the vehicle speed). Depending on the case, the display mode can use the instrument image (or the analog measuring device) or a digital measuring device or counter form. The display mode of the vehicle information may vary depending on the number of parts of vehicle information that are on the monitor 202 is displayed, or the combination can be controlled.

For example, an analog meter can be used to display vehicle speed when the number of pieces of vehicle information is on the monitor 202 is displayed, less than or equal to a predetermined number (e.g. 3rd ) is. Meanwhile, a digital counter format can be used for display when the number of pieces of vehicle information to be displayed is greater than or equal to the predetermined number. The display in digital counter format requires a smaller display space than that analog meter and may allow the monitor display screen to display more information. The types or number of pieces of information on the monitor 202 is displayed, it can mainly be determined as a function of driving conditions that indicate whether the vehicle is driving.

An element with the same function as the element already described in the above-mentioned embodiment is provided with the same reference symbol and, for the sake of simplicity, has not been described repeatedly. If only part of the configuration is described, the configuration of the above embodiment can be applied to the other parts.

(Fifteenth modification)

Viewed from the front, if the pointer body section 931 overlaps with a numerical value corresponding to the scale, the modeling section F2 of the display control device 201 a 3D model with a drawing object 276 generate this numerical value higher (or further ahead) than the pointer body section 931 of the pointer object 273 represents. This configuration enables the display screen to display the numerical value as in 29 shown floating at the position overlapping with the pointer. Therefore, it is possible to reduce one way in which the pointer object 273 hides a numerical value and it is difficult for the driver to read the numerical value near the pointer.

The display control device 201 can one with the pointer object 273 display overlapping numerical value floating to the page higher than the pointer object 273 to be. The higher side indicates a direction from the base plate object 271 to the pointer object 273 and corresponds to the same direction as the front or front.

A color adjustment section F23 is advantageous for the modeling section F2 provided that is configured to match the pointer object 273 floating overlapping numerical value. As in 30th shown, the color adjustment section F23 a hue for each part that forms the stereoscopic instrument model. The color adjustment section F23 sets the drawing object 276 used for hovering a hue different from one hue for the other numerical values. Of several of the scale objects 272 is a scale object 272A according to the drawing object 276 configured to be the same or a similar color as the drawing object 276 to use. The color adjustment section F23 unifies colors of drawing objects 276 and the drawing object 276 corresponding scale object 272A . This mode enables the driver to more easily recognize the correspondence relationship between the scale and the numerical value indicated by the pointer.

As a premise, there are predetermined standard colors (hereinafter referred to as basic characters colors) for numerical values and standard colors (hereinafter referred to as primary colors) for scale objects 272 . The color adjustment section F23 uses a color different from the drawing base color and the scale base color for the drawing object 276 for floating. For example, if the base color of the drawing is blue and the base color of the scale is black, the color of the drawing object becomes 276 than green and the color of the scale object 272A configured as a darker green (with reduced intensity and saturation). The similar type of color is characterized by the same hue and different intensity or saturation.

When viewed from the front, the display control device 201 if a numerical value linked to the scale does not match the pointer body section 931 overlapped, use a mode in which the numerical value is at the same height as the top of the scale object 272 floats according to the numerical values. In this case, the modeling section creates F2 a stereoscopic instrument model that represents the drawing object 276 , which shows the numerical value associated with the scale by the amount of projection β , the scale object linked to the numerical value 272 is assigned, above the base plate surface. This mode also makes it easy to see the correspondence between the scale and the numerical value. If the numerical value is displayed floating from the base plate surface, the original position for arranging the numerical value on the base plate surface is advantageously darkened or with an object 961 provided with a darkened version of the floating drawing object 276 is comparable.

(Sixteenth modification)

In the above embodiment, the mode for changing the amount of projection is β according to the distance from the pointer object 273 described, but the present invention is not limited to this. So the amount of advance β for every scale object 272 for example without exception to a predetermined value (e.g. 0 , 5α ) greater than 0 be set, regardless of the positions of the pointer object 273 .

This mode also shows at least the scale near the pointer protruding from the base plate. The distance between the scale and the plane for arranging the pointer is smaller than the distance between the base plate and the pointer. It is possible to suppress the degree of visual shift between the pointer and the scale based on the driver's viewpoint positions. It is possible to prevent the visibility of the vehicle information from deteriorating due to a separation between the base plate and the pointer.

(Seventeenth modification)

The above-mentioned embodiments mainly show the mode for reproducing the instrument image, which simulates the type of an analog measuring device including the pointer rotating over the scale surface, but the present invention is not limited to this. As in 31 shown, the instrument image can simulate the type of an analog counter or measuring device (bar counter) in which the pointer moves over a bar-shaped scale surface with linearly arranged scales.

(Eighteenth modification)

Similar to Patent Document 1, the above-mentioned reproducing section can F4 the direction of one outside the monitor 202 Capture the existing light source and display an image that mainly reflects the pointer shadow caused by the light source, an instrument gloss mode or a mode of reflected light that is reflected by the instrument.
