Description

Vehicle display system

Technical Field

The present disclosure relates to a vehicle display system.

Background

The conventional vehicle instrument panel is generally a mechanical instrument panel and can display basic vehicle operation information such as the rotating speed of an engine, the speed per hour of a vehicle, water temperature, oil quantity and the like. Some vehicle models also consider adding a small liquid crystal display screen in a mechanical instrument panel to display supplementary information such as gear, tire pressure, oil consumption and the like. With the electric and intelligent requirements of automobiles, the automobile instrument panel is gradually changed from a mechanical instrument panel to a full liquid crystal display instrument panel. The full liquid crystal instrument panel can not only display the information, but also display functions such as a navigation map, multimedia and the like. Compared with the traditional mechanical instrument panel, the full liquid crystal instrument panel has more comprehensive displayed information and can provide richer driving information and intelligent service for the driver. However, the most basic function of the conventional mechanical dashboard or the full liquid crystal dashboard is to provide clear and definite vehicle operation information for the driver.

However, the driver sometimes adjusts the position of the steering wheel and/or the seat for driving comfort, or when drivers of different heights and sizes drive the same vehicle, the driver may also need to adjust the position of the steering wheel and/or the seat. In such a case, since the position and size of the parameter icon showing the vehicle operation information on the conventional mechanical dashboard and the conventional all-liquid crystal dashboard are often fixed, there is a possibility that the driver's view of the dashboard is blocked by the steering wheel after the steering wheel and/or the seat are adjusted in position, which may result in the driver not being able to directly read the vehicle operation information displayed on the dashboard. In particular, while the driver is driving the vehicle, it is necessary to confirm various vehicle operation information (such as the speed per hour, the engine speed, and fuel efficiency) required for driving while looking ahead. If the line of sight is blocked by the steering wheel and the driver cannot easily and clearly read the required vehicle operating information, there can be a driving safety concern.

The present disclosure relates generally to a vehicle display system for adjusting a parameter icon displayed on a meter display device after a driver adjusts the position of a steering wheel and/or a driving seat as needed so that the parameter icon is displayed to the driver without being blocked by the steering wheel, thereby enabling the driver to easily and clearly read various vehicle operation information required for driving on the meter display device while driving the vehicle.

Hereinafter, the present exemplary embodiment will be described with reference to fig. 1 to 4. Fig. 1 is an explanatory diagram showing a vehicle 1 mounted with a vehicle display system 10 of the present disclosure. As shown in fig. 1, the vehicle display system 10 of the present exemplary embodiment includes: a meter display device 11 having a display screen 11a, the meter display device 11 being capable of displaying a parameter icon (see fig. 3) showing vehicle operation information; a steering wheel sensor 12 for detecting positional information of the steering wheel 20, the steering wheel 20 being provided on the front side of the driver 30 with respect to the instrument display device 11 and being movable in the up-down front-rear direction with respect to the instrument display device 11; an eye sensing device 13 provided on a vehicle front side, the eye sensing device 13 sensing eye position information of a driver 30 seated in a driver seat 40, the driver seat 40 being movable in up-down front-rear directions with respect to the meter display device 11; and a control unit 14, wherein the control unit 14 processes the received information. In the present exemplary embodiment, the display screen 11a is, for example, a liquid crystal display screen.

Fig. 2 is a block diagram illustrating the configuration of the vehicle display system 10 of the present disclosure to further clarify the relationship between the above-described members. As shown in fig. 2, the control unit 14 is connected to the steering wheel sensor 12, and detects position information of the steering wheel 20 by receiving a signal from the steering wheel sensor 12. The control unit 14 is connected to the eye sensor device 13, and receives a signal from the eye sensor device 13 to acquire eye position information of the driver 30 seated in the driver seat 40. The control unit 14 generates a control signal based on the detected positional information of the steering wheel 20 and the positional information of the driver seat 40. The control unit 14 is connected to the meter display device 11, and adjusts the parameter icon displayed on the meter display device 11 by transmitting a control signal to the meter display device 11.

Fig. 3 shows a state in which the display content of the instrument display device 11 is viewed from the driver seat. As shown in fig. 3, the meter display device 11 is provided at a position on the back side of the steering wheel 20 when viewed from the driver seat. The steering wheel 20 is provided with a plurality of spokes 20a, and a hollow portion 20b is formed inside the steering wheel 20 and between the spokes 20 a. The driver 30 views the display contents on the meter display device 11 from the hollow portion 20b.

As shown in fig. 3, a parameter icon 11a-1 showing the vehicle speed per hour, a parameter icon 11a-2 showing the engine speed, a parameter icon 11a-3 showing the fuel consumption, the vehicle interior temperature, and the like are generally displayed on the display screen 11a of the meter display device 11.

In the driving preparation phase, the driver 30 seated in the driving seat sometimes adjusts the position of the steering wheel and/or the seat for driving comfort. After the driver has adjusted the position of the steering wheel and/or the seat as needed, the parameter icon displayed on the instrument display device 11 may be blocked by the spokes 20a of the steering wheel 20, and the driver 30 may not be able to easily and clearly read the vehicle operation information required for driving displayed on the instrument display device 11 during the subsequent driving of the vehicle, which may cause a risk in terms of driving safety. In view of this, in the vehicle display system 10 of the present disclosure, the parameter icons displayed on the display screen 11a of the meter display device 11 are adjusted as follows.

In the vehicle 1, the eye sensing device 13 is fixed with respect to the vehicle 1, and therefore it is conceivable to construct a world coordinate system of the vehicle 1 with the optical center of the eye sensing device 13 as an origin. Here, the world coordinate system is not limited to the construction of the world coordinate system with the optical center of the eye sensor device 13 as the origin, and may be a fixed position in the vehicle 1, and may be constructed with the center of the control unit 14 or the meter display device 11 as the origin, for example. Since the eye sensing device 13 senses the face of the driver 30 to acquire the eye position information of the driver 30 in the present exemplary embodiment, if the world coordinate system is constructed with the optical center of the eye sensing device 13 as the origin, there is no need to perform conversion between the camera coordinate system and the world coordinate system after acquiring the eye position information of the driver 30, and therefore it is preferable to construct the world coordinate system with the optical center of the eye sensing device 13 as the origin.

In addition, in the vehicle 1, since the position of the meter display device 11 is fixed with respect to the vehicle 1, the position information, which is the coordinates of the meter display device 11, can be determined in advance in the world coordinate system with the optical center of the eye sensing device 13 as the origin. In the present exemplary embodiment, the position information of the meter display device 11 is stored in the control portion 14 in advance.

In the vehicle 1, a steering wheel 20 is movable in the vertical front-rear direction with respect to a meter display device 11, and a steering wheel sensor 12 is provided in the steering wheel 20, and the steering wheel sensor 12 detects a change in position of the steering wheel 20 after a driver 30 adjusts the steering wheel 20 as needed, generates a corresponding position change signal, and transmits the position change signal to a control unit 14. The control unit 14 updates the position information, which is the coordinates of the steering wheel 20, in a world coordinate system with the optical center of the eye sensing device 13 as the origin, based on the received position change signal. For convenience of explanation, in the present exemplary embodiment, the steering wheel 20 is simply regarded as a plane, and after the position information, which is the coordinates of the steering wheel 20 after the position adjustment, is updated, the position information, which is the coordinates of the plane in which the hollow portion 20b of the steering wheel 20 is located, can be specified accordingly.

Similarly, in the vehicle 1, the driver seat 40 is adjustable so as to be movable in the up-down front-rear direction with respect to the instrument display device 11. After the driver 30 completes the position adjustment of the driver seat 40 as needed, the eye sensing device 13 provided on the vehicle front side senses the face of the driver 30, generates a corresponding image data signal, and transmits the image data signal to the control section 14. The control unit 14 updates the eye position information, which is the eye coordinates of the driver 30, in the world coordinate system with the optical center of the eye sensing device 13 as the origin, based on the received image data signal of the face of the driver 30. In the present exemplary embodiment, the eye sensing device 13 employs, for example, a binocular camera that can determine the distance by parallax calculation of two images, and therefore can easily acquire the eye position coordinates of the driver 30.

As described above, after the adjustment of the steering wheel 20 and/or the driver seat 40 by the driver 30 is completed, the control unit 14 acquires the position information of (the hollow portion 20b of) the steering wheel 20 and/or the driver seat 40 after the adjustment and the eye position information of the driver 30 as described above. At this time, when the meter display device 11 is viewed from the driver 30, a plane in which the hollow portion 20b of the steering wheel 20 is located and a plane in which the display screen 11a of the meter display device 11 is located form an overlapping portion in a direction from the eyes of the driver 30 to the meter display device 11. Since the control unit 14 acquires the position information of (the hollow portion 20b of) the steering wheel 20 and the eye position information of the driver 30 and stores the position information of the meter display device 11 in advance, the control unit 14 can estimate the size of the overlap portion in the constructed world coordinate system based on this information and further estimate the position information of the area corresponding to the overlap portion on the display screen 11a of the meter display device 11. This area is an area formed when the above-mentioned overlapping portion is projected onto the display screen 11a in the direction in which the driver 30 views the meter display device 11.

Then, the control unit 14 is configured to adjust the parameter icons 11a-1, 11a-2, and 11a-3 displayed on the display screen 11a of the meter display device 11 so that the parameter icons 11a-1, 11a-2, and 11a-3 are displayed in the areas corresponding to the overlapping portions on the display screen 11a of the meter display device 11. Thus, when the meter display 11 is viewed from the driver 30, the parameter icons 11a-1, 11a-2, 11a-3 are not blocked by the spokes 20a of the steering wheel 20. The driver can read the vehicle operation information shown by these parameter icons 11a-1, 11a-2, 11a-3 without being obstructed by the steering wheel. Thus, even after the steering wheel 20 and/or the driver seat 40 are adjusted in position, the driver 30 can be ensured to easily and clearly read various pieces of vehicle operation information required for driving on the meter display device 11 while driving the vehicle, and safety and comfort can be improved.

Next, for ease of understanding, a change in the parameter icon on the instrument display device 11 when the position of the steering wheel 20 and/or the driver seat 30 is changed will be described with reference to fig. 4A to 4H. Needless to say, the present invention is not limited to the following examples.

Fig. 4A shows a variation of the parameter icons on the display screen 11a of the meter display device 11 in a case where the steering wheel 20 is adjusted upward with respect to the meter display device 11 and the driver seat 30 is kept unchanged. As shown in fig. 4A, the left side is a state before adjustment, and the right side is a state after adjustment is completed. In the state before adjustment, when the display panel 11a is viewed from the driver 30, the plane in which the hollow portion 20b of the steering wheel 20 is located and the plane in which the display panel 11a of the instrument display device 11 is located form an overlapping portion corresponding to the overlapping area 11ab on the display panel 11 a. When the driver 30 adjusts the steering wheel 20 upward, as shown in the right-hand diagram of fig. 4A, the overlap area 11ab is reduced to an overlap area 11ab ', and the parameter icons 11a-3 are blocked by the spokes 20a of the steering wheel 20, and at this time, the control unit 14 is configured to cause the parameter icons 11a-3 to be displayed in the overlap area 11ab' on the display screen 11a, that is, to float the parameter icons 11a-3 showing fuel efficiency, in-vehicle temperature information, and the like. Thus, the driver can read the vehicle operation information indicated by these parameter icons 11a-1, 11a-2, 11a-3 without being obstructed by the steering wheel.

Fig. 4B shows a variation of the parameter icons on the display screen 11a of the meter display device 11 in a case where the steering wheel 20 is adjusted downward relative to the meter display device 11 and the driver seat 30 is kept unchanged. When the overlap area 11ab is reduced to the overlap area 11ab ', and the parameter icons 11a-1 and 11a-2 are blocked by the spokes 20a of the steering wheel 20, the control unit 14 is configured to cause the parameter icons 11a-1 and 11a-2 to be displayed in the overlap area 11ab' on the display screen 11a, that is, to cause the parameter icon 11a-1 indicating the vehicle speed and the parameter icon 11a-2 indicating the engine speed to float downward and to be reduced as appropriate.

Fig. 4C shows a variation of the parameter icons on the display screen 11a of the meter display device 11 in a case where the steering wheel 20 is adjusted backward with respect to the meter display device 11 and the driver seat 30 is kept unchanged. When the overlap area 11ab is reduced to the overlap area 11ab 'and the parameter icons 11a-3 are blocked by the spokes 20a of the steering wheel 20, the control unit 14 is configured to display the parameter icons 11a-3 in the overlap area 11ab' on the display screen 11a, that is, to float the parameter icons 11 a-3.

Fig. 4D shows a variation of the parameter icons on the display screen 11a of the meter display device 11 in a case where the steering wheel 20 is adjusted forward with respect to the meter display device 11 and the driver seat 30 is kept unchanged. The overlap area 11ab becomes larger than the overlap area 11ab', and the parameter icons 11a-1, 11a-2, 11a-3 are not blocked by the spokes 20a of the steering wheel 20, and the control unit 14 does not need to adjust the parameter icons 11a-1, 11a-2, 11 a-3.

Fig. 4E shows a variation of the parameter icons on the display screen 11a of the meter display device 11 with the steering wheel 20 held constant and the driver seat 30 adjusted forward relative to the meter display device 11. When the overlap area 11ab is reduced to the overlap area 11ab 'and the parameter icons 11a-1 and 11a-2 are blocked by the spokes 20a of the steering wheel 20, the control unit 14 is configured to display the parameter icons 11a-1 and 11a-2 in the overlap area 11ab' on the display screen 11a, that is, to float the parameter icons 11a-1 and 11a-2 downward and reduce the size as appropriate.

Fig. 4F shows a variation of the parameter icons on the display screen 11a of the instrument display device 11 with the steering wheel 20 held constant and the driver seat 30 adjusted backward relative to the instrument display device 11. When the overlap area 11ab is reduced to the overlap area 11ab 'and the parameter icons 11a-3 are blocked by the spokes 20a of the steering wheel 20, the control unit 14 is configured to display the parameter icons 11a-3 in the overlap area 11ab' on the display screen 11a, that is, to float the parameter icons 11 a-3.

Fig. 4G shows a variation of the parameter icons on the display screen 11a of the meter display device 11 with the steering wheel 20 held constant and the driver seat 30 adjusted upward relative to the meter display device 11. When the overlap area 11ab is reduced to the overlap area 11ab 'and the parameter icons 11a-1 and 11a-2 are blocked by the spokes 20a of the steering wheel 20, the control unit 14 is configured to display the parameter icons 11a-1 and 11a-2 in the overlap area 11ab' on the display screen 11a, that is, to float the parameter icons 11a-1 and 11a-2 downward and reduce the size as appropriate.

Fig. 4H shows a variation of the parameter icons on the display screen 11a of the meter display device 11 with the steering wheel 20 held constant and the driver seat 30 adjusted downward relative to the meter display device 11. When the overlap area 11ab is reduced to the overlap area 11ab 'and the parameter icons 11a-3 are blocked by the spokes 20a of the steering wheel 20, the control unit 14 is configured to display the parameter icons 11a-3 in the overlap area 11ab' on the display screen 11a, that is, to float the parameter icons 11 a-3.

Above, a plurality of embodiments are schematically illustrated for ease of understanding. However, it goes without saying that the present invention is not limited to the above-described examples. In this case, similarly, the control unit 14 may be configured to be able to display the parameter icon in the overlap area on the display screen 11a, so that the driver 30 can read the vehicle operation information on the meter display device 11 without being blocked by the steering wheel 20.

In the above embodiment, the control unit 14 adjusts the parameter icons 11a-1, 11a-2, and 11a-3 by changing the positions or sizes of the parameter icons 11a-1, 11a-2, and 11a-3 displayed on the display screen 11 a. However, the method of adjusting the parameter icons 11a-1, 11a-2, and 11a-3 is not limited to this, and the method may be configured such that the parameter icons can be displayed in the overlapping area on the display screen 11a, and the parameter icons 11a-1, 11a-2, and 11a-3 may be adjusted by changing the shape of the parameter icons, for example.

In addition, in the present exemplary embodiment, the vehicle display system 10 is also configured such that the driver 30 can manually adjust the size or position of the parameter icon displayed on the meter display device 11, and thus the driver 30 can adjust the parameter icon according to his or her own needs, which can further improve driving safety and comfort.

In addition, in driving the vehicle, the vehicle operation information may be divided into vehicle operation information that is important to the driver 30 and vehicle operation information that is relatively unimportant to the driver 30. For example, the vehicle speed per hour, the engine speed, and the like are vehicle operation information important to the driver 30, and the fuel efficiency, the in-vehicle temperature, and the like are vehicle operation information that is not important to the driver 30. In the present exemplary embodiment, the parameter icons include a constantly displayed icon that is always displayed on the display screen 11a of the meter display device 11, and a wheel-motion displayed icon that wheel-motion displays vehicle operation information at regular time intervals. As shown in fig. 3, two circular parameter icons are constant display icons respectively showing the vehicle speed per hour and the engine speed, which are always displayed on the display screen 11a during the vehicle operation, and a quadrangular parameter icon is a wheel movement display icon showing the fuel consumption, the in-vehicle temperature, the alarm mark, or the like, which displays the vehicle operation information (the fuel consumption, the in-vehicle temperature, or the alarm mark) at regular time intervals during the vehicle operation. In this way, the driver 30 can always easily and clearly read the vehicle operation information (vehicle speed per hour, engine speed, etc.) important to the driver 30 while driving the vehicle. In addition, in the present exemplary embodiment, the vehicle display system 10 is also configured such that the driver 30 can manually set the vehicle operation information indicated by the constant display icon and the wheel movement display icon, and the driver 30 can set the vehicle operation information according to the need of the driver, thereby further improving the driving safety and the comfort.

Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Accordingly, all changes and modifications are intended to be included within the scope of the present disclosure as defined in the appended claims.
