Description

The present invention relates to a meter unit for a vehicle.

Vehicles are equipped with meter units for displaying driving information such as vehicle speed and engine rpm. Meter units include conventional analog mechanical meters and those that display meters and the like as images on an image display device such as a liquid crystal display. When an image display device is used, an image combining displays showing various driving information is displayed on the display screen of the image display device. The image to be displayed is generated by acquiring the necessary information according to the display mode. Images corresponding to each display mode are generated by generating part images from image data for displaying the information required for that display mode and the acquired information, and arranging these part images in a predetermined layout.

Patent document 1 discloses a meter unit that uses an image display device. The meter unit can switch between a normal first display mode screen and a second display mode screen that displays a night view image, and the screen switching is displayed as an animation. The second display mode screen is also generated using the night view image acquired from a night view camera.

Patent No. 4442672

The images corresponding to each display mode are designed according to the concept of the vehicle in which the meter unit is installed. For example, a meter unit to be installed in a compact car aimed at young women will be designed with images that young women are likely to like. However, different drivers have different tastes, so this would mean forcing a design that does not respect those preferences on the driver.

The present invention was conceived in light of the above circumstances, and aims to provide a vehicle meter unit that respects the driver's preferences.

To solve the above problems, the present invention provides the following technical solutions:

The vehicle meter unit provided by the present invention is characterized by comprising an image display device that displays an image, a storage unit that stores a first image that displays driving information and a second image that displays the driving information and is different from the first image, and a display control unit that switches the image displayed on the image display device between the first image and the second image.

In a preferred embodiment of the present invention, the driving information includes engine speed.

In a preferred embodiment of the present invention, the first image is an image that displays the driving information three-dimensionally, and the second image is an image that displays the driving information two-dimensionally.

According to the present invention, the storage device stores a first image and a second image that are different from each other and display the same driving information. The image displayed on the display device can be switched between the first image and the second image by the display control device. Therefore, the driver can change the image displayed on the display device to an image of his/her preference.

Other features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

The following describes the embodiment of the present invention in detail with reference to the drawings.

Figure 1 is a schematic block diagram showing the configuration of a car 1 to which a vehicle meter unit 2 according to the first embodiment is applied. As shown in Figure 1, the car 1 is equipped with the vehicle meter unit 2, a vehicle speed sensor 31, an engine ECU (Electric Control Unit) 32, a fuel level sensor 33, and a CVT (Continuously Variable Transmission)-ECU 34. Note that the car 1 also has other components, but these are not shown in Figure 1.

The vehicle speed sensor 31 is a sensor that detects the vehicle speed of the vehicle 1. The vehicle speed sensor 31 generates a pulse signal synchronized with the rotation of the wheels and outputs it to the vehicle meter unit 2. The meter ECU 4 of the vehicle meter unit 2 calculates the vehicle speed of the vehicle 1 based on the frequency of the pulse signal input from the vehicle speed sensor 31. Note that the pulse signal of the vehicle speed sensor 31 may be input to an ECU other than the meter ECU 4, and the meter ECU 4 may obtain the vehicle speed calculated by that ECU.

The engine ECU 32 performs electronic control to control the engine, and is implemented by a microcomputer equipped with a CPU and memory. The engine ECU 32 controls the start, stop, and engine speed of the engine. The engine ECU 32 controls the engine speed input from the engine speed sensor to a target speed by adjusting the throttle valve. The engine ECU 32 outputs the engine speed detected by the engine speed sensor to the vehicle meter unit 2.

The fuel remaining amount sensor 33 is a sensor that detects the remaining amount of fuel. The fuel remaining amount sensor 33 outputs a detection signal corresponding to the remaining amount of fuel to the vehicle meter unit 2. The meter ECU 4 of the vehicle meter unit 2 calculates the remaining amount of fuel based on the input detection signal. Note that the detection signal of the fuel remaining amount sensor 33 may be input to an ECU other than the meter ECU 4, and the meter ECU 4 may acquire the remaining amount of fuel calculated by that ECU.

The CVT-ECU 34 performs electronic control to control the continuously variable transmission, and is implemented by a microcomputer equipped with a CPU and memory. The CVT-ECU 34 detects the operating position of the shift lever (shift position) using a shift position sensor, and sets the gear and the speed ratio of the continuously variable transmission according to the detection result. The CVT-ECU 34 outputs the shift position detected by the shift position sensor to the vehicle meter unit 2.

Although not shown in the figure, the vehicle meter unit 2 receives various driving information from other sensors and the ECU. Other driving information that is input includes, for example, navigation information, accumulated mileage, time, outside air temperature, direction indication information, parking brake information, information indicating whether the lights are on or off, seat belt fastening/unfastening information, coolant temperature, fault diagnosis information, security information, and the like. Note that the driving information input to the vehicle meter unit 2 is not limited.

The vehicle meter unit 2 is a unit that processes and displays information input from each sensor and each ECU in a form that can be visually understood by the driver. The vehicle meter unit 2 is disposed on the instrument panel so as to face the driver's seat. The vehicle meter unit 2 includes a meter ECU 4, a liquid crystal display 5, and an operation switch 6.

The meter ECU 4 performs electronic control to process and display the driving information input from each sensor and each ECU, and is realized by a microcomputer equipped with a CPU and memory. The meter ECU 4 displays an image on the liquid crystal display 5 based on the input driving information.

The meter ECU 4 acquires different driving information and displays different images depending on the display mode. The display mode may be changed according to the driver's operation, or may be changed automatically depending on the situation. For example, the display mode can be changed to a display mode that displays fuel efficiency and cruising distance by the driver's operation, and if an abnormality occurs, the display mode is automatically changed to a display mode that displays a warning. In addition, when a car navigation system is used, the meter ECU 4 automatically switches to a turn-by-turn display mode when the car 1 approaches a right or left turn point. In the turn-by-turn display mode, the meter ECU 4 acquires information on the distance to the right or left turn point, the lane to be traveled, and the direction to turn from the car navigation system (not shown), and displays an image reflecting this information (see Figures 3 and 4). The meter ECU 4 switches the set display mode according to the driver's operation of an operating means (not shown). In addition, the meter ECU 4 switches the set display mode according to a warning signal input from another ECU, or a judgment result based on information input from a sensor or another ECU.

The meter ECU 4 also switches the set image type in response to an operation signal input from the operation switch 6. The meter ECU 4 displays different images depending on the set image type even in the same display mode. The driving information shown in the displayed image is set according to the display mode, so it does not differ depending on the image type. However, the same driving information is displayed with a completely different impression depending on the set image type. In this embodiment, the meter ECU 4 can switch the image type among four different image types. As shown in FIG. 1, the meter ECU 4 has a memory unit 41, a drawing unit 42, and a display control unit 43.

The storage unit 41 stores a program for controlling the liquid crystal display 5, image data for drawing on the liquid crystal display 5, and the like. The storage unit 41 stores first image information, second image information, third image information, and fourth image information corresponding to four types of image.

The first image information is image data for generating an image of the first image type with the theme of "advanced quality". The image of the first image type is an image that incorporates displays and new movements that cannot be achieved with a physical meter, and gives the driver a sense of depth, a sense of floating, and advanced technology. The second image information is image data for generating an image of the second image type with the theme of "clean and refined". The image of the second image type is an image with a flat and orthodox design that minimizes display elements, and gives the driver a sense of refinement. The third image information is image data for generating an image of the third image type with the theme of "exciting and active". The image of the third image type is an image with a mechanical design that gives a sense of depth to the center, and gives the driver a sense of the fun of driving. The fourth image information is image data for generating an image of the fourth image type with the theme of "conventional". The image of the fourth image type is an image designed to resemble a conventional physical meter, and gives the driver a sense of the texture and instrument feel of a conventional physical meter. Note that these image types are merely examples and are not limited to those described.

Each piece of image information includes image data of the display parts for each piece of driving information. Examples of the display parts include a speedometer that displays the vehicle speed, a tachometer that displays the engine RPMs, a fuel gauge that displays the remaining fuel level, and a shift indicator that displays the shift position. Each piece of image information also includes layout information for each display mode. The layout information includes, for example, information specifying the display parts (driving information) to be displayed, information on the position of each display part, and information specifying the size of each display part. The memory unit 41 stores this information for each piece of image information.

The display control unit 43 reads out corresponding information from the storage unit 41 according to the set image type and the set display mode, and outputs the read out information to the drawing unit 42. For example, when the first image type is set and the turn-by-turn display mode is set, the display control unit 43 reads out image data of display parts such as the speedometer, tachometer, fuel gauge, and shift display, and layout information for the turn-by-turn display mode from the first image information.

The drawing unit 42 is a functional block for generating images to be displayed on the liquid crystal display 5, and is realized by, for example, a drawing LSI. The drawing unit 42 generates images to be displayed on the liquid crystal display 5 based on driving information such as engine speed input from the engine ECU 32 and information read from the storage unit 41 and input by the display control unit 43. Specifically, the drawing unit 42 generates each part image by reflecting the contents of the driving information corresponding to the image data of the display parts, and generates an image to be displayed on the liquid crystal display 5 by combining these in a layout according to the layout information. Note that the method of generating the image is not limited. The meter ECU 4 outputs the image data of the image generated by the drawing unit 42 to the liquid crystal display 5 for display.

Figure 2 is an example of a flowchart for explaining the image display process performed by the meter ECU 4. The image display process is executed at a predetermined timing.

First, driving information is acquired from each sensor and each ECU (S1). Next, the set display mode is acquired (S2), and the set image type is acquired (S3).

Next, it is determined whether the image type is the first image type (S4). If it is the first image type (S4: YES), the display control unit 43 reads out the corresponding information of the first image information from the storage unit 41 (S5). If it is not the first image type (S4: NO), it is determined whether the image type is the second image type (S6). If it is the second image type (S6: YES), the display control unit 43 reads out the corresponding information of the second image information from the storage unit 41 (S7). If it is not the second image type (S6: NO), it is determined whether the image type is the third image type (S8). If it is the third image type (S8: YES), the display control unit 43 reads out the corresponding information of the third image information from the storage unit 41 (S9). If it is not the third image type (S8: NO), it is determined that the image type is the fourth image type, and the display control unit 43 reads out the corresponding information of the fourth image information from the storage unit 41 (S10).

Next, the drawing unit 42 generates an image to be displayed on the liquid crystal display 5 (S11). Next, the generated image is displayed on the liquid crystal display 5 (S12). Specifically, image data of the generated image is output to the liquid crystal display 5, and the image is displayed on the liquid crystal display 5. The above processing is executed at a predetermined timing, and an image corresponding to the change in each driving information is displayed as a moving image on the liquid crystal display 5. That is, an image in which the displayed numerical value and the position or angle of the pointer change according to the vehicle speed and engine speed that change from moment to moment is displayed. In addition, when the display mode or image type is switched, the displayed image is switched to an image of the corresponding display mode and image type. Note that, when the display mode is switched, an image that connects the image before the switch and the image after the switch may be generated. In this case, an image that changes like an animation is displayed. Similarly, when the image type is switched, an image that connects the image before the switch and the image after the switch may be generated, or an end image of the image type before the switch and a start image of the image type after the switch may be generated.

Note that the image display process performed by the meter ECU 4 is not limited to that shown in the flowchart above.

The operation switch 6 is a switch for switching the image type. The operation switch 6 outputs an operation signal to the meter ECU 4 according to the operation. In this embodiment, the operation switch 6 has one push button, and outputs an operation signal every time the driver presses the push button. The meter ECU 4 switches the set image type in the order of the first image type, the second image type, the third image type, and the fourth image type every time an operation signal is input. Note that while driving (when the vehicle speed is equal to or higher than a predetermined speed), the operation switch 6 does not output an operation signal in order to avoid danger due to operation. Alternatively, the meter ECU 4 may be designed not to accept an operation signal. Note that the operation switch 6 is not limited to this. For example, the operation switch 6 may have four push buttons corresponding to each image type, and the meter ECU 4 may set the corresponding image type based on the operation signal input.

The liquid crystal display 5 is, for example, a TFT-type transmissive liquid crystal display. However, the liquid crystal display 5 is not limited to this. The liquid crystal display 5 is disposed on the front side (rear side of the vehicle) of the vehicle meter unit 2. The liquid crystal display 5 has a display screen 5a that faces the front side. In other words, the display screen 5a is disposed so as to face the driver's seat. The liquid crystal display 5 displays an image on the display screen 5a based on image data input from the meter ECU 4.

Figures 3 and 4 show examples of images displayed on the display screen 5a of the liquid crystal display 5. Both Figures 3 and 4 are examples of images in the turn-by-turn display mode.

Figure 3 is an example of an image when the first image type is set. As shown in Figure 3, the image displayed on the display screen 5a includes a speedometer 81, a tachometer 82, a fuel gauge 83, a shift indicator 84, a turn-by-turn indicator 85, an odometer 86, a clock 87, a temperature gauge 88, and a warning message indicator 89.

The speedometer 81 is a parts image generated based on the vehicle speed detected by the vehicle speed sensor 31. The speedometer 81 is located at the left end of the display screen 5a and displays the vehicle speed as a numerical value. The tachometer 82 is a parts image generated based on the engine speed detected by the engine speed sensor (input via the engine ECU 32). The tachometer 82 is located at the center in the left-right direction of the display screen 5a and displays the engine speed. The tachometer 82 is a three-dimensional cylinder displayed as an instrument with numbers indicating the engine speed displayed along the side of the cylinder, and a pointer displayed as a band indicating the current engine speed at its tip position, superimposed on the instrument on the side of the cylinder. Note that the pointer is not displayed in FIG. 3.

The fuel gauge 83 is a parts image generated based on the remaining fuel detected by the fuel level sensor 33. The fuel gauge 83 is located at the right edge of the display screen 5a, and indicates the remaining fuel level by the number of dots that have changed color among the multiple dots. The shift indicator 84 is a parts image generated based on the shift position detected by the shift position sensor (input via the CVT-ECU 34). The shift indicator 84 is located on the right side of the display screen 5a (between the tachometer 82 and the fuel gauge 83), and indicates the shift position with its initial letter, an alphabet.

The turn-by-turn display 85 is a parts image generated based on navigation information input from a car navigation system. The turn-by-turn display 85 is located above the tachometer 82 in the center of the display screen 5a in the left-right direction. The turn-by-turn display 85 displays the distance to the right or left turn point, the lane to travel in, and the direction to turn, which are input from the car navigation system, so that the information can be intuitively recognized. In FIG. 3, the distance to the right or left turn point is shown numerically on the right side, and the lane to travel in is shown by changing the color of one of the arrows indicating the driving divisions of each lane displayed on the left side, and the large arrow displayed between them indicates the direction to turn.

The odometer 86 is a part image that indicates the accumulated distance traveled. The odometer 86 is located at the bottom right of the display screen 5a and displays the accumulated distance traveled numerically. The clock 87 is a part image that indicates the time. The clock 87 is located at the top right of the display screen 5a and displays the time digitally. The thermometer 88 is a part image that indicates the outside temperature. The thermometer 88 is located at the bottom left of the display screen 5a and displays the outside temperature digitally. The warning and guidance display 89 is a part image that indicates various warnings and guidance. The warning and guidance display 89 is located at the top center in the left-right direction of the display screen 5a and displays lit marks indicating various warnings and guidance.

As shown in FIG. 3, when the first image type is set, the tachometer 82, which is located in the center of the display screen 5a and occupies a wide area, is displayed in a special three-dimensional image. This image is an image that displays driving information in three dimensions, and corresponds to the "first image" of the present invention. The first image type image incorporates displays and new movements that cannot be achieved with a physical meter, giving the driver a sense of depth, dimension, a sense of floating, and advanced technology.

Figure 4 is an example of an image when the second image type is set. As shown in Figure 4, the image displayed on the display screen 5a includes a speedometer 91, a tachometer 92, a fuel gauge 93, a shift indicator 94, a turn-by-turn indicator 95, an odometer 96, a clock 97, a temperature gauge 98, and a warning message indicator 99.

The speedometer 91 is a parts image generated based on the vehicle speed detected by the vehicle speed sensor 31. The speedometer 91 is positioned to the right of the display screen 5a, and displays the vehicle speed as a numerical value. The fuel gauge 93 is a parts image generated based on the remaining amount of fuel detected by the fuel level sensor 33. The fuel gauge 93 is positioned on the right side of the display screen 5a, surrounding the speedometer 91 as a right-half semicircular level gauge. The fuel gauge 93 displays a level according to the remaining amount of fuel as a level gauge.

The shift indicator 94 is a parts image generated based on the shift position detected by the shift position sensor (input via the CVT-ECU 34). The shift indicator 94 is positioned toward the left of the display screen 5a, and displays the shift position with its initial letter, an alphabet. The tachometer 92 is a parts image generated based on the engine speed detected by the engine speed sensor (input via the engine ECU 32). The tachometer 92 is positioned on the left side of the display screen 5a, surrounding the shift indicator 94 as a left-half semicircular level gauge. The tachometer 92 displays a level according to the engine speed as a level gauge.

The turn-by-turn display 95 is a parts image generated based on navigation information input from a car navigation system. The turn-by-turn display 95 is located in the center of the display screen 5a, between the speedometer 91 and fuel gauge 93, and the shift display 94 and tachometer 92. The turn-by-turn display 95 is similar to the turn-by-turn display 85 in FIG. 3, with a large arrow indicating the turn direction on the upper side, a display indicating the lane to travel on the lower side, and a numerical value indicating the distance to the right or left turn point between them.

The odometer 96 is a part image that indicates the accumulated mileage. The odometer 96 is located at the bottom right of the turn-by-turn display 95 and displays the accumulated mileage numerically. The thermometer 98 is a part image that indicates the outside temperature. The thermometer 98 is located at the bottom left of the turn-by-turn display 95 and displays the outside temperature digitally. The warning and guidance display 89 is a part image that indicates various warnings and guidance. The warning and guidance display 89 is located above the turn-by-turn display 95 and displays lit marks that indicate various warnings and guidance. The clock 97 is a part image that indicates the time. The clock 97 is located at the top left of the display screen 5a and displays the time digitally.

As shown in FIG. 4, when the second image type is set, the image is a simple, conventionally designed image without excessive decoration. This image displays driving information in a two-dimensional manner, and corresponds to the "second image" of the present invention. The second image type image is a flat, conventionally designed image with a minimum of display elements, giving the driver a sense of sophistication. Note that illustrations and explanations of examples of images when the third image type is set and examples of images when the fourth image type is set are omitted.

Next, the effects of the vehicle meter unit 2 according to the first embodiment will be described.

According to this embodiment, the storage unit 41 stores first image information, second image information, third image information, and fourth image information corresponding to four types of image. The display control unit 43 reads out the corresponding information from the storage unit 41 according to the set image type and the set display mode. The drawing unit 42 generates an image to be displayed on the liquid crystal display 5 based on the read out information. The generated image is displayed on the liquid crystal display 5. Therefore, even when the meter ECU 4 displays an image based on the same driving information in the same display mode, the meter ECU 4 displays a different image depending on the set image type. The driver can switch the set image type by operating the operation switch 6. Therefore, the driver can change the image displayed on the liquid crystal display 5 to a preferred image from among the four types of image. In other words, the vehicle meter unit 2 can display an image type that respects the driver's preference.

In this embodiment, the driving information shown in the image displayed on the LCD display 5 includes the engine speed. Therefore, the driver can recognize the current engine speed by looking at the image displayed on the LCD display 5.

According to this embodiment, when the first image type is set, the image is an image that displays the driving information three-dimensionally, and when the second image type is set, the image is an image that displays the driving information two-dimensionally. Therefore, the vehicle meter unit 2 allows the driver to select between the first image type image and the second image type image, which give completely different impressions.

In the present embodiment, a case has been described in which an image type can be selected from four types, but this is not limited to this. The selectable image types may be two or three types, or may be five or more types. As the number of image types increases, the driver can select an image type that is more in line with his or her preferences. Therefore, the increasingly diverse preferences of drivers can be better satisfied. On the other hand, as the number of image types increases, the amount of information stored in the memory unit 41 increases, and therefore the memory capacity of the memory unit 41 needs to be increased.

In this embodiment, the vehicle meter unit 2 is described as having a liquid crystal display 5 as an image display device, but this is not limited to the above. Instead of the liquid crystal display 5, the vehicle meter unit 2 may be provided with another display that displays images, such as an organic electroluminescence display or a plasma display.

5 and 6 show an example of an image displayed on the display screen 5a of the liquid crystal display 5 in the vehicle meter unit 2 according to the second embodiment. The vehicle meter unit 2 according to the second embodiment further includes a seven-segment display 52, a fuel gauge display 53, and a display panel 7, and differs from the vehicle meter unit 2 according to the first embodiment in that the vehicle speed, which is one of the driving information, is displayed on the seven-segment display 52, and the remaining fuel level is displayed on the fuel gauge display 53. The display panel 7 is a plate-shaped member made of a transparent resin such as acrylic, with black paint printed on it, and is disposed on the rear side of the vehicle relative to the liquid crystal display 5 and the like. The display panel 7 includes a light-shielding portion 71 on which paint is printed to prevent light from passing through, and a first window 72, a second window 73, and a third window 74, which are transparent portions on which paint is not printed. As shown in Figures 5 and 6, the first window 72 transmits the image displayed on the display screen 5a of the liquid crystal display 5, the second window 73 transmits the display on the display surface 52a of the seven-segment display 52, and the third window 74 transmits the display on the display surface 53a of the fuel gauge display 53. As shown in Figures 5 and 6, the boundaries between the display screen 5a, the display surface 52a, and the display surface 53a and the light-shielding portion 71 are not noticeable, so the driver has the illusion that there are no boundaries and that the display board 7 is one large display screen. Therefore, while using a small, low-cost liquid crystal display 5, the driver can feel the luxury of being equipped with a large liquid crystal display.

As shown in Figures 5 and 6, the vehicle speed is displayed on the display surface 52a of the seven-segment display 52, which is visible through the second window 73 located on the right side of the display panel 7. The remaining fuel level is displayed on the display surface 53a of the fuel gauge display 53, which is visible through a third window 74 located below the second window 73. Therefore, the display positions of the vehicle speed and the remaining fuel level are fixed regardless of the image type and display mode.

Figure 5 is an example of an image when the first image type is set. As shown in Figure 5, the image displayed on the display screen 5a displays the same part images as in Figure 3, namely, a tachometer 82, a shift indicator 84, a turn-by-turn indicator 85, an odometer 86, a clock 87, a temperature gauge 88, and a warning guide indicator 89. On the other hand, the image displayed on the display screen 5a does not display the speedometer 81 and the fuel gauge 83.

As shown in FIG. 5, when the first image type is set, the tachometer 82, which is located in the center of the display screen 5a (also approximately in the center of the display panel 7) and occupies a wide area, is displayed as a special three-dimensional image, giving the driver a sense of depth, dimension, floating, and advanced technology.

Figure 6 is an example of an image when the second image type is set. As shown in Figure 6, the image displayed on the display screen 5a displays the same part images as in Figure 4, namely, a tachometer 92, a shift indicator 94, a turn-by-turn indicator 95, an odometer 96, a clock 97, a temperature gauge 98, and a warning guide indicator 99. On the other hand, the image displayed on the display screen 5a does not display the speedometer 91 and the fuel gauge 93.

As shown in FIG. 6, when the second image type is set, the image is a simple and orthodox design without excessive decoration, giving the driver a sense of sophistication. Note that illustrations and explanations of example images when the third image type is set and example images when the fourth image type is set are omitted.
