First display means for sequentially switching to the next item according to the display order of the plurality of items stored in the order storage means and displaying information in the first display area;
An operation signal output means for outputting a first operation signal in response to an operation by a user;
When the first operation signal is output from the operation signal output means in a state where the first display means displays information in the first display area, the information displayed in the first display area is changed to two. And a second display means for displaying in the second display area among the two display areas.

  In this manner, when the first operation signal is output in a state where information is displayed in the first display area, the information displayed in the first display area is displayed in the second display area. Thus, in the second display area, the information of the item desired by the user is always displayed, and in the first display area, the items are switched and displayed in the display order stored in the order storage means. be able to. Therefore, convenience can be enhanced.

  According to a second aspect of the present invention, when the first operation signal is output from the operation signal output means while the first display means displays information in the first display area, You may make it provide the item memory | storage means to memorize | store the item of the information currently displayed on a display area in a non-volatile memory as an item displayed on a 2nd display area.

  In this way, even when the supply of power to the display device is stopped (power off), when the power supply is started again (power on), the second display area has a user's power. Information on a desired item can be displayed.

According to a third aspect of the present invention, the first display means also performs the sequence even when the first operation signal is output from the operation signal output means in a state where information is displayed in the first display area. Information may be displayed in the first display area by sequentially switching to the next item in accordance with the display order of the plurality of items stored in the storage means.

  By doing in this way, when the information currently displayed on the 1st display area is displayed on the 2nd display area, it can prevent displaying the information on the same item on the 1st display area. .

  According to a fourth aspect of the present invention, the first display means switches the items in the display order stored in the order storage means and displays the first display in a state where the information is displayed in the second display area. When displaying information in the area, information of items other than the information items displayed in the second display area may be displayed.

  By doing so, it is possible to prevent the same item of information from being displayed in the first display area when the information is being displayed in the second display area.

  In addition to the first operation signal, the operation signal output means outputs a second operation signal different from the first operation signal in accordance with an operation by the user. When the second operation signal is output from the operation signal output means, the first display means switches the items in the display order stored in the order storage means and displays information in the first display area. May be.

  Further, as shown in claim 6, the first display means switches the items in the display order stored in the order storage means each time the second operation signal is output from the operation signal output means. Information may be displayed in the display area.

  By doing in this way, the item displayed on a 1st display area can be switched at the timing which a user desires.

  Further, as shown in claim 7, when the second operation signal is output from the operation signal output means, the first display means switches the items at predetermined time intervals in the display order stored in the order storage means. The information may be displayed in the first display area.

  By doing in this way, the item displayed on the 1st display field can be changed only by outputting the 2nd operation signal once (namely, the user is one operation).

  According to another aspect of the present invention, the operation signal output means includes one operation unit operated by the user, and the first operation signal and the second operation signal are the user operations on the operation unit. It is good also as the signal output according to the aspect.

  By doing in this way, since it can prevent that the number of operation parts increases, it can control that mounting space becomes large and cost goes up.

  However, as shown in claim 9, the operation signal output means includes two operation units operated by the user, and the first operation signal and the second operation signal are determined by the user for each operation unit. It is good also as the signal output according to operation.

  According to a tenth aspect of the present invention, the display section is provided in the vehicle interior, and the first display means and the second display means are displayed in the first display area and the second display area. Vehicle information may be displayed as information to be performed. That is, you may apply to the display apparatus for vehicles.

  In addition, the space in which the operation unit and the like can be mounted is limited in the passenger compartment. Therefore, when applied to a display device for a vehicle, as described above, the operation signal output means includes one operation unit operated by the user, and two different operation signals corresponding to the operation mode of the user with respect to the operation unit. Is particularly preferable because it is not necessary to increase the number of operation units.

  The meter device 10 employs, for example, a combination meter that collectively displays instruments such as a speedometer, a tachometer, and a fuel meter, an odometer, a flasher indicator, various warnings, and the like on a display 6 (corresponding to a display unit of the present invention). be able to.

  The display 6 includes a first display area and a second display area, as shown in FIG. And the meter apparatus 10 in this Embodiment displays the information (vehicle information) of several items in the 1st display area and the 2nd display area so that switching is possible. In the present embodiment, as an example, vehicle information desired by a user (for example, a driver) can be stored in a switchable manner, and the vehicle information desired by the user is always displayed in the second display area. Further, an example in which another vehicle information is displayed in a switchable manner in the first display area will be described.

  However, the present invention is not limited to this, and a display device that includes a display including two display areas and displays information of a plurality of items in the display area in a switchable manner may be adopted as long as the display device is used. And the object of the present invention can be achieved.

  The vehicle information items include, for example, brightness adjustment, cruising range, average fuel efficiency after refueling, instantaneous fuel efficiency, total average fuel efficiency, average vehicle speed, travel time, customization, clearance sonar / door open, energy flow, ACC (Adaptive Cruise Control) / LKA (Lane Keeping Assist system), tire pressure, etc. can be used. However, the vehicle information is not limited to these. In the present embodiment, items of vehicle information to be switched and displayed will be simply described as item A, item B, item C, item D, item E, and item F.

  As shown in FIG. 1, the meter device 10 includes a CPU (Central Processing Unit) 1, ROM (Read Only Memory) 2, RAM (Random Access Memory) 3, EEPROM (Electronically Erasable and Programmable Read) as a meter ASSY (assembly). Only Memory (nonvolatile memory) 4, drawing IC (Integrated Circuit) 5, display 6, CAN (Controller Area Network) communication I / F (interface) 7, power supply I / F (interface) 8, and meter ASSY (CPU 1) Are provided with an operation unit 9 for outputting an operation signal. The meter device 10 is electrically connected to the first computer 21, the second computer 22, and the third computer 23 via a transmission path (CAN communication bus). Furthermore, the meter device 10 is configured to be electrically connectable to the battery 31 via a switch 32 (for example, an ignition switch of a vehicle).

  The meter device 10 includes a CPU 1, a ROM 2, a RAM 3, an EEPROM 4, a drawing IC 5, and a bus line (not shown) that connects these components, and executes a vehicle information display process that will be described later. To do.

  The CPU 1 operates with power supplied from the battery 31 via the power supply I / F 8 when the switch 32 is in the on state. The CPU 1 performs arithmetic processing using the RAM 3 as a work area based on the control program stored in the ROM 2, the data stored in the ROM 2 and the EEPROM 4, the operation signal output from the operation unit 9, and the like. And image data stored in the ROM 2 are output to the drawing IC 5. Further, the CPU 1 acquires the vehicle information data output from the first computer 21, the second computer 22, and the third computer 23 via the CAN communication I / F 7 and outputs the vehicle information data to the drawing IC 5. To do.

  Note that the ROM 2 stores image data such as instruments displayed on the display 6 and the display order (data indicating the display order) of items when the vehicle information is switched and displayed in the first display area of the display 6. (Order storage means). In this embodiment, an example in which items A, B, C, D, E, and F are displayed in this order is employed. The item F is displayed in the same order after returning to the item A. Accordingly, the display order (display) is displayed in the order of item A, item B, item C, item D, item E, and item F on the ROM 2 and the item F is displayed in the same order after returning to the item A. Data indicating the order) is stored.

  The RAM 3 is used as a work area, and temporarily stores results of processing executed by the CPU 1. The EEPROM 4 stores items of vehicle information (data indicating the items) to be displayed in a second display area which will be described later. Note that data indicating the display order of the above items may be stored in the EEPROM 4.

  The drawing IC 5 performs arithmetic processing based on the control signal and data acquired from the CPU 1, for example, a synchronization signal composed of a horizontal synchronization signal and a vertical synchronization signal, red (R) and green (G) which are the three primary colors of light. Display control for the display 6 is performed by outputting an RGB signal, a display clock (CLK) signal, and the like composed of the blue and blue (B) signals.

  As a result, instruments such as a speedometer, a tachometer, and a fuel meter, an odometer, a flasher indicator, various warnings, and the like are displayed on the display 6. Further, as shown in FIG. 2, vehicle information is displayed on a part of the display 6 (first display area, second display area).

  The display 6 is provided at a position facing the driver's seat in the passenger compartment, and a known color liquid crystal display or the like can be adopted. In the present embodiment, an example (see FIG. 2) in which the first display area and the second display area for displaying vehicle information provided in a part of the display 6 are arranged vertically will be described. However, the present invention is not limited to this. For example, the first display area and the second display area may be arranged on the left and right, or may be arranged on the upper left and lower right. That is, it is not necessary to arrange the first display area and the second display area side by side. Furthermore, the size (area) of the first display area and the second display area may be the same or different.

  The operation unit 9 outputs two different operation signals to the CPU 1 according to the operation mode by the user, and for example, a well-known push button switch or the like can be employed (operation signal output means). For example, one operation unit 9 is arranged around a steering wheel (not shown) or the display 6. The CPU 1 determines the user's operation mode for the operation unit 9 based on the operation signal output from the operation unit 9.

  In the present embodiment, the CPU 1 will be described by adopting an example in which the operation mode can be determined by dividing into two types of the first operation mode and the second operation mode different from the first operation mode. As each operation mode, for example, the first operation mode is one-click of the operation unit 9 (the operation unit 9 is pressed once within a specified time. Hereinafter, also referred to as a single press), and the second operation mode is Long pressing of the operating unit 9 (pressing the operating unit 9 for a predetermined time or more) can be employed. That is, the operation unit 9 includes an operation signal (corresponding to the second operation signal of the present invention) indicating that the operation unit 9 is single-pressed and an operation signal indicating that the operation unit 9 is pressed long (present invention). (Corresponding to the first operation signal).

  As described above, the user's operation mode for the operation unit 9 is determined based on the operation signal output from the operation unit 9 in order to change the process executed for each operation mode. As a specific example of the process executed in accordance with the operation mode, a process for switching the item of the vehicle information displayed in the first display area of the display 6 based on the data indicating the display order stored in the ROM 2, the display 6 is a process of storing the vehicle information item displayed in the first display area 6 in the EEPROM 4 and displaying the vehicle information of the item in the second display area. The relationship between each operation mode and the process to be executed is set in advance and stored in the ROM 2 or the like. In the present embodiment, in the case of a single push (when the second operation signal is output), the vehicle information displayed in the first display area based on the data indicating the display order stored in the ROM 2 is displayed. When the item switching process is executed and the button is long-pressed (when the first operation signal is output), the vehicle information item displayed in the first display area is stored in the EEPROM 4 and the vehicle information of the item is stored. An example of executing the process of displaying the image in the second display area is adopted.

  In this way, by changing the process executed for each operation mode of the user with respect to the operation unit 9 (the process of switching the item of vehicle information displayed in the first display area and the display in the first display area The vehicle information item is stored in the EEPROM 4 and the vehicle information of the item is displayed in the second display area), and the number of operation units 9 can be prevented from increasing, so that the mounting space increases. And it can suppress that cost goes up.

  Furthermore, the space in which the operation part 9 etc. can be mounted is limited in the vehicle interior. Therefore, a display device that does not require an increase in the number of operation units 9 is suitable for the meter device 10 that is a display device for a vehicle.

  In the present embodiment, the operation unit 9 will be described using an example in which the operation unit 9 is directly connected to the CPU 1, but the present invention is not limited to this. For example, the connection may be made via the CAN communication I / F 7.

  In addition, the meter device 10 includes various measuring data and various detection data for displaying the above-described instruments such as a speedometer, a tachometer, and a fuel meter, an odometer, a flasher indicator, various warnings, and vehicle information. Obtained from the second computer 22 and the third computer 23.

  In the present embodiment, the first computer 21, the second computer 22, and the third computer 23 (three computers connected via a CAN communication bus) output the above-described various measurement data and various detection data. An example is used for explanation, but the present invention is not limited to this. For example, any device that outputs the above-described various measurement data and various detection data, such as a sensor or a computer electrically connected to the CPU 1 without using a CAN communication bus, can be employed. Further, the number of devices that output the various measurement data and the various detection data is not particularly limited.

  Here, the display processing operation of the vehicle information of the meter device 10 according to the present embodiment will be described with reference to FIGS. 2 starts when the switch 32 is turned on and power is supplied from the battery 31, for example, and the switch 32 is turned off and the power supply from the battery 31 is stopped. And end.

  First, in step S10, regarding the second display area, as shown in FIG. 4B, vehicle information of items (here, item B) stored in the EEPROM 4 is displayed on the display 6. The items displayed in the second display area are items stored in step S14 described later. Therefore, if the item is not stored in step S14 (if it does not proceed to step S14), nothing is displayed in the second display area. However, in such a case, guidance information indicating that items to be displayed in the second display area are not stored, guidance information indicating that items to be displayed in the second display area can be stored, etc. May be displayed. In this way, the user can be informed that the item to be displayed can be stored in the second display area.

  On the other hand, regarding the first display area, as shown in FIG. 4A, vehicle information of an item to be displayed first (here, item A) based on data indicating the display order of items stored in the ROM 2 (That is, the vehicle information of the first item in the order) is displayed on the display 6. However, when the vehicle information is displayed in the first display area, the item displayed in the second display area is skipped, and the vehicle of the next item in the data indicating the display order of the items stored in the ROM 2 It is preferable to display information. For example, when the vehicle information of item A is displayed in the second display area, the vehicle information of item B is displayed in the first display area. That is, it is preferable to display vehicle information of items other than the vehicle information items displayed in the second display region in the first display region. By doing in this way, it can prevent displaying the vehicle information of the same item on both a 1st display area and a 2nd display area.

  In step S11, it is determined whether or not the operation unit 9 has been operated based on whether or not an operation signal has been output from the operation unit 9. If it is determined that the operation signal has been output, it is determined that the operation unit 9 has been operated. The process proceeds to S12, and if it is determined that the operation signal is not output, the operation unit 9 is regarded as not being operated, and the process proceeds to Step S15.

  In step S12, the operation time of the operation unit 9 by the user is determined. That is, it is determined based on the operation signal output from the operation unit 9 whether the user's operation mode for the operation unit 9 is a long press or a single press. And when it determines with it being single press, it progresses to step S13, and when it determines with it being long press, it progresses to step S14.

  As described above, when the user's operation mode for the operation unit 9 is a single press, the vehicle information displayed in the first display area of the display 6 based on the data indicating the display order stored in the ROM 2. Execute the item switching process. On the other hand, when the user's operation mode for the operation unit 9 is long press, the vehicle information item displayed in the first display area of the display 6 is stored in the EEPROM 4 and the vehicle information of the item is stored in the second display area. The process of displaying in the display area is executed. Therefore, whether the determination of this step S12 acquired the operation signal which shows switching of the item of the vehicle information currently displayed on the 1st display area of the display 6 based on the data which show the display order memorize | stored in ROM2. The vehicle information item displayed in the first display area of the display 6 is stored in the EEPROM 4, and the operation signal indicating that the vehicle information of the item is displayed in the second display area is acquired. In other words.

  Therefore, if it is determined that the user's operation mode for the operation unit 9 is a single press based on the operation signal, the vehicle displayed in the first display area based on the data indicating the display order stored in the ROM 2 It is assumed that an operation signal indicating switching of information items has been acquired, and the process proceeds to step S13. On the other hand, if it is determined that the user's operation mode for the operation unit 9 is long press based on the operation signal, an operation signal indicating that the item is stored and the vehicle information of the item is displayed in the second display area is acquired. The process proceeds to step S14.

  In step S13, the item is not changed for the second display area (here, item B is continuously displayed). On the other hand, with respect to the first display area, the process of switching the item of the vehicle information displayed in the first display area of the display 6 is executed based on the data indicating the display order stored in the ROM 2 (the first display area). Display means, for example, the vehicle information of item A is switched to the vehicle information of item B and displayed).

  In other words, regarding the first display area, the vehicle information of the next item is displayed on the display 6 according to a preset order. That is, every time the meter device 10 according to the present embodiment determines that the user's operation mode with respect to the operation unit 9 is a single press (every time an operation signal indicating that the user has pressed the operation unit 9 is output). ), Vehicle information is displayed in the first display area based on the display order data stored in the ROM 2 (first display means). Therefore, each time the button is pressed, the vehicle information is displayed by switching the items in the order of item A, item B, item C, item D, item E, and item F. 4 and 6, the solid line arrow indicates that the operation unit 9 has been single-pressed.

  However, in the present embodiment, in the state where the vehicle information is displayed in the second display area, an operation signal indicating that a single press has been performed is output from the operation unit 9 and stored in the ROM 2. When the vehicle information is displayed in the first display area of the display 6 by switching the item based on the data indicating the vehicle information, the vehicle information of items other than the vehicle information item displayed in the second display area is displayed. You may make it do. For example, as shown in FIG. 4A, when the vehicle information of the item B is displayed in the second display area, when an operation signal indicating that the vehicle information is single-pressed is output from the operation unit 9, In the display area 1, the item B is skipped in the display order data and the vehicle information of the item C is displayed. By doing in this way, when displaying the vehicle information in the second display area, it is possible to prevent the vehicle information of the same item from being displayed in the first display area.

  In step S15, it is determined whether or not the power is turned off. If it is determined that the power is turned off, the process ends (end). If it is determined that the power is not turned off, the process proceeds to step S10. Return.

  Here, the process of step S14 that is performed when it is determined in step S12 that it is long-pressed will be described. In step S14, the vehicle information item currently displayed in the first display area is stored in the EEPROM 4 as an item to be displayed in the second display area (item storage means). Furthermore, regarding the second display area, the vehicle information currently displayed in the first display area is displayed (second display means). On the other hand, for the first display area, the process of switching the item of vehicle information displayed in the first display area of the display 6 is executed based on the data indicating the display order stored in the ROM 2.

  As described above, when the operation signal indicating that the operation unit 9 is long pressed is output in the state where the vehicle information is displayed in the first display area, the vehicle displayed in the first display area. By displaying the information in the second display area, the vehicle information of the item desired by the user is always displayed in the second display area, and stored in the ROM 2 in the first display area. Items can be switched and displayed in the display order. Therefore, the highly convenient meter device 10 can be provided.

  Further, in the state where the vehicle information is displayed in the first display area, when an operation signal indicating that the operation unit 9 has been pressed for a long time is output, the vehicle information displayed in the first display area By storing the item in the EEPROM 4 as an item to be displayed in the second display area, even if the power supply to the meter device 10 is stopped (switch 32 off), the power supply starts again (switch 32 on). When this is done, vehicle information of items desired by the user can be displayed in the second display area. However, the object of the present invention can be achieved without storing the vehicle information items displayed in the first display area in the EEPROM 4 as items to be displayed in the second display area.

  Note that the first display area is also stored in the ROM 2 even when an operation signal indicating that a long press has been output from the operation unit 9 while vehicle information is being displayed in the first display area. The vehicle information may be displayed in the first display area by switching items based on the data indicating the display order (see FIG. 3).

  For example, in the state where the vehicle information of item D is displayed in the first display area and the vehicle information of item B is displayed in the second display area, an operation indicating that the operation unit 9 has been pressed for a long time When the signal is output, the vehicle information of the item D displayed in the first display area is displayed for the second display area as shown in FIG. On the other hand, regarding the first display area, as shown in FIG. 5A, the vehicle information of the item E, which is the next item, is displayed based on the data indicating the display order. In FIG. 5, a thick solid arrow indicates that the operation unit 9 has been pressed for a long time.

  In addition, after doing in this way, when the vehicle information of the item D is displayed on the 2nd display area (refer to Drawing 6 (b)), the operation signal which shows having been single-pressed from operation part 9 is outputted. Each time, the item D is skipped and the vehicle information items A to F are displayed in order in the first display area (see FIG. 6A). By doing in this way, when displaying the vehicle information in the second display area, it is possible to prevent the vehicle information of the same item from being displayed in the first display area.

  By doing in this way, when the vehicle information currently displayed on the 1st display area is displayed on the 2nd display area, displaying the vehicle information of the same item on the 1st display area is prevented. Can do.

  In recent years, the number of items of vehicle information displayed on the meter device 10 that is a display device for vehicles can be 10 or more. Therefore, a display device that can always display one vehicle information desired by the user while switching other vehicle information is suitable for the meter device 10.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not restrict | limited to the embodiment mentioned above at all, and various deformation | transformation are possible in the range which does not deviate from the meaning of this invention.

  For example, in the above-described embodiment, the example using the operation unit 9 that outputs two different operation signals to the CPU 1 according to the operation mode by the user has been described, but the present invention is limited to this. is not. Two operation units operated by the user may be provided, and two different operation signals may be output according to the user's operation on each operation unit (operation signal output means). That is, one of the operation units operates on an operation signal (second operation signal) indicating execution of switching processing of items of vehicle information displayed in the first display area based on data indicating the display order stored in the ROM 2. ), And the other operation unit outputs an operation signal (first operation signal) indicating execution of processing for displaying the vehicle information displayed in the first display area in the second display area, or the first An item of vehicle information displayed in the display area is stored in the EEPROM 4 and an operation signal (first operation signal) indicating execution of processing for displaying the vehicle information of the item in the second display area is output. To.

  Further, in the above-described embodiment, every time it is determined that the user's operation mode with respect to the operation unit 9 is a single press (each time an operation signal indicating that a single press is performed from the operation unit 9), The vehicle information is displayed in the first display area based on the display order data stored in the ROM 2 (the vehicle information item displayed in the second display area may be skipped). However, the present invention is not limited to this.

  For example, when it is determined that the user's operation mode with respect to the operation unit 9 is a single press (when an operation signal indicating that a single press is performed from the operation unit 9 is output), the display order data stored in the ROM 2 is used. The vehicle information may be switched and displayed in the first display area every predetermined time (the vehicle information item displayed in the second display area may be skipped).

  Further, when power is supplied to the meter device 10, the vehicle information is displayed in the first display area at predetermined intervals based on the display order data stored in the ROM 2 (displayed in the second display area). The vehicle information item may be skipped).
