Description

The present invention relates to a control system or the like that performs control to switch between screens of different formats that display information about the current situation.

For example, in a control system such as a vehicle speed measuring device that notifies the approach of a target to be notified, the position information of the target to be notified is stored and held, and the position of the vehicle detected by GPS and the position of the target to be notified are in a predetermined proximity. There are some that issue an alarm when a relationship is established (for example, Patent Document 1, etc.).

In the case of the target informing device such as the above-mentioned Patent Document 1, for example, when the current position of the detection object to be notified and the vehicle reaches a set distance (for example, 1 km, 500 m, etc.), "500 m ahead , ○○.” (○○ outputs an audio warning such as information specifying a target (loop coil, etc.), and outputs and displays related information on the display in text form.

These control systems, for example, alert the driver to the proximity of a vehicle speed-measuring device, thereby helping to prevent the driver from unintentionally driving too fast. In particular, since vehicle speed measurement devices are generally installed in places where speeding is likely to occur, they can alert drivers to speeding in dangerous places. . Thus, such a control system contributes to safe driving and the like.

Such a control system is equipped with a screen that displays the acquired current situation, such as the acceleration and speed of the vehicle, on a meter when the vehicle is not approaching a notification target such as a vehicle speed measuring device (Patent Document 2, 3).

For example, the user may set one screen including the desired meter from among screens of different formats displaying information about these current conditions to be displayed, and the set screen is displayed. .

However, it has become possible to obtain information about the current situation directly from a wide variety of sensors and from the vehicle side, and the types of meters are increasing in order to display information about the wide variety of current situations. Therefore, if a screen is prepared for each type of meter, the number of screens increases, and there is a problem that it is difficult to select a desired meter.

Also, if multiple meters are displayed on one screen, there is a risk that the combination of meters included in that screen will be different from what the user desires. I had a problem that I couldn't.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a control system or the like that enables a user to select and display a meter necessary for the display, and that can accurately display many types of information.

In order to achieve the above object, the control system according to the present invention provides (1) a control system for controlling meter display based on acquired data, the control system comprising a plurality of meter display areas on one screen; , a type of meter display selected by the user is displayed in at least one meter display area on the one screen.

By doing so, the user can select the meter that is necessary for the user and display it on the screen. A control system that has a plurality of meter display areas on one screen and can display a plurality of types of information on the screen by selecting the meters that are necessary for the user. etc. can be provided.

In particular, as in (13), the screen may be arranged at a position visible to the driver of the vehicle, and the acquired data may be data that changes as the vehicle moves. While driving a vehicle, it is difficult to switch screens or select the type of meter display. However, by doing so, for example, the type of meter display that the driver wants to see while driving the vehicle can be selected and displayed while the vehicle is not being driven.

For the acquired data, it is preferable to use, for example, data existing in a memory such as a RAM or a storage means such as a register. The acquisition of data may be triggered by a predetermined event such as when there is a change in data or at a predetermined time interval, for example.

The meter display may be, for example, a display indicating a weighing scale. The weighing instrument may be, for example, a tool, machine, or device for weighing. Quantification, for example, means measuring the quantity of the state of a physical phenomenon. For example, the amount may be indicated by a predetermined weighing unit (a standard for weighing). For example, the amount of physical phenomena includes length, mass, time, current, temperature, amount of material, luminous intensity, angle, solid angle, area, volume, angular velocity, angular acceleration, speed, acceleration, frequency, rotational speed, wave number, density, force, moment of force, pressure, stress, viscosity, kinematic viscosity, work, power, mass flow rate, flow rate, heat quantity, thermal conductivity, specific heat capacity, entropy, quantity of electricity, electric field strength, voltage, electromotive force, capacitance, magnetic field strength, magnetomotive force, magnetic flux density, magnetic flux, inductance, electrical resistance, electrical conductance, impedance, power, reactive power, apparent power, power energy, reactive power energy, apparent power energy, Attenuation of electromagnetic waves, power density of electromagnetic waves, radiant intensity, luminous flux, luminance, illuminance, sound power, sound pressure level, vibration acceleration level, concentration, neutron emission rate, radioactivity, absorbed dose, absorbed dose rate, kerma, kerma rate , irradiation dose, irradiation dose rate, dose equivalent or dose equivalent rate, fineness, specific gravity, and the like.

For example, when there is a change in the acquired data, the meter display may be configured to be updated to show the change. For example, if there is a change in the acquired data, it may be updated and displayed at all times. It may be configured such that the update display is performed and the update display is not performed when there is a change but the change does not follow a predetermined pattern. Alternatively, regardless of data update, the display may be updated according to a predetermined rule, such as at predetermined time intervals. A particularly good configuration is to update and display the meter display at a timing that allows the user to recognize that the meter display reflects the current situation. The timing at which the user can recognize that the meter display reflects the current situation may vary depending on the type of data displayed on the meter.

For example, a configuration may be adopted in which information regarding these various current conditions is displayed on a meter based on data regarding current conditions acquired from various sensors and other devices. Even if the types of meters increase in this way, a desired meter can be selected and displayed without preparing a screen for each type of meter and without increasing the number of screens. In addition, although a plurality of meters are displayed on one screen, at least one meter display area on the screen displays the type of meter selected by the user. It is possible to display a meter that can be used, and it is possible to grasp a lot of information accurately.

A plurality of types of meter display may be provided, and control may be performed to display the type of meter display selected by the user. As a configuration for displaying the type of meter display selected by the user, for example, information for specifying the type of meter display selected by the user is stored in a storage means, and the user stored in the storage means The specified type of meter display may be performed based on the information for specifying the selected type of meter display. For example, if the meter is of a type that the user can perceive changes in milliseconds, it should be updated in milliseconds. For example, if the meter is of a type that allows the user to perceive changes in units of seconds, it should be updated in units of seconds. For example, if the meter is of a type that allows the user to perceive changes on a minute-by-minute basis, it should be updated on a minute-by-minute basis. For example, if the meter is of a type that allows the user to perceive a change in units of one hour, the meter should be updated in units of one hour. For example, if the meter is of a type that allows the user to perceive a change on a daily basis, it may be updated on a daily basis.

For the selection of the type of meter display by the user, for example, it is preferable to present options for selecting which meter display and allow the user to select from the presented options. The options may be presented, for example, by the display means, and for example, the options may be displayed on the same screen as the screen having a plurality of meter display areas. For example, it is preferable to display the options by switching from a state in which a screen including a plurality of meter display areas is displayed to a state in which a screen for displaying options is displayed.

As the screen, it is preferable to use a screen such as a dot-matrix display whose display contents can be changed. The screen may be, for example, the entire display area of the display means, or may be a part thereof. For example, the plurality of meter display areas may be arranged so that the respective meter areas do not overlap each other, but they may be arranged so as to partially overlap each other. In the case of this configuration, it is preferable to provide a visible indication of the amount to be metered in the non-overlapping portion. Alternatively, for example, it is preferable to make the overlapping portion translucent so that both the lower side (back side) and the upper side (front side) can be visually recognized. (2) The meter display area A configuration may be adopted in which the type of meter display selected by the user is provided for each unit.

In this way, the user can select which type of meter display is to be displayed in which meter display area on the screen, and the desired type of meter can be displayed in the desired arrangement.

As a configuration for allowing the user to select the type of meter display for each meter display area, for example, the user first selects the meter display area to be selected, and then selects which type of meter display is to be performed for the selected meter display area. Alternatively, the type of meter display to be displayed may be selected first, and the selected type of meter display may be selected in which meter display area. For the selection of the meter display area, for example, it is preferable to present options for selecting which meter display area and allow the user to select from the presented options. The options may be presented, for example, by the display means, and for example, the options may be displayed on the same screen as the screen having a plurality of meter display areas. For example, a screen including a plurality of meter display areas may be switched to a display screen for options to display the options.

(3) Control may be performed to display a predetermined display other than the meter display, and the meter display of the type selected by the user or the predetermined display selected by the user may be performed in each of the meter display areas.

In this way, when the user selects the predetermined display, the selected predetermined display other than the meter display is displayed in the meter display area. Therefore, the user can visually recognize the contents of the selected predetermined display other than the meter display by simply looking at the screen with the intention of viewing the meter display. In this way, the contents of the selected predetermined display other than the meter display can be viewed with the same movement of the line of sight as when viewing the meter display. For example, the user selects to display a first type of meter display in the first meter display area, and selects to display a predetermined display in a second meter display area different from the first meter display area. In this case, by moving the line of sight to the first meter display area and the second meter display area of one screen, the first type of meter display and the predetermined display can be visually recognized naturally. In particular, as shown in (13), the screen is arranged at a position visible to the driver of the vehicle, and the acquired data is data that changes according to the movement of the vehicle. When you move your eyes from the screen to check the data that changes according to the movement of the vehicle, you can immediately and naturally see the predetermined display other than the meter display.

The predetermined display is a display other than a meter display, for example, a clock indicating the time in the embodiment, a display of the tide of the day, etc. good.

In this way, the weighed amount and the non-weighed amount can be confirmed on one screen at the same time. Moreover, the non-measured quantity is displayed in the meter display area, and the user-selected quantity can be displayed and visually recognized in the same manner as the meter display.

(4) It is preferable to provide different types of predetermined displays that can be displayed in the meter display area, and to display a predetermined display of a type selected from the plurality of predetermined display types in the meter display area.

In this way, for example, the user can cause the type of predetermined display selected from among the different types of predetermined display to be displayed in the meter display area. Therefore, it is possible to select a predetermined display necessary for the user and display it on the screen, so that it is possible to provide a control system or the like capable of accurately displaying a plurality of types of information.

(5) For example, it may be configured such that different types of predetermined display can be selected for each display content, and the predetermined display of the selected type of display content may be performed. However, in this way, if a different type of predetermined display than the one currently selected is desired, it is necessary to reselect the type of predetermined display each time.

Therefore, it is preferable to switch the display content as the predetermined display according to a predetermined switching trigger. In this way, for example, the display content is switched in response to a predetermined switching trigger within the meter display area on the screen. Therefore, the content of the predetermined display is automatically switched within the meter display area without reselecting the type of the predetermined display each time. As a result, there is no difficulty in grasping which option corresponds to which predetermined display, and there is no need to take time to find a desired option from a large number of options.

(6) A configuration may be adopted in which the selectable meter display and the selectable predetermined display are displayed without distinction as selection items on the selection screen for selection by the user.
In this way, the user can select the meter display or the predetermined display without being conscious of it.

(7) The number of the plurality of meter display areas displayed on one screen is three, and the three meter display areas are provided in the longitudinal direction of the display screen, and the center of the three meter display areas is the meter display area. It is preferable that the meter display area has a display mode that is more conspicuous than the other two meter display areas.

In this way, the longitudinal direction of the screen can be utilized as effectively as possible, and a large meter display area can be secured. Furthermore, by making the central meter display area of the three meter display areas more conspicuous than the other two meter display areas, it is possible to select what you mainly want to see in the central meter display area, can be placed.

(8) The number of the plurality of meter display areas displayed on one screen is three, and the three meter display areas are provided in the longitudinal direction of the display screen, and the meter display areas are partially overlapped. , and the meter display area located in the forefront of the overlapping may be the meter display area in the middle of the three meter display areas.

By doing so, the central meter display area is felt to be in front of the other two meter display areas and stands out. Therefore, for example, the central meter display area can be positioned as the main meter display area, and the left and right meter display areas can be positioned as sub meter display areas, respectively, and can be selected and arranged.
(9) A plurality of screens having the plurality of meter display areas may be provided, and these screens may be switched and displayed in a predetermined pattern.

In this way, many meter display areas can be displayed without reselecting them. As the predetermined pattern, for example, it is preferable to set the elapse of a certain period of time.
(10) It is preferable that at least two of the plurality of screens having the plurality of meter display areas have the same format.

In this way, it is possible to increase the possibility that the contents of the meter display area can be visually recognized simply by moving the line of sight on the premise of this same format. In particular, as shown in (13), the screen is arranged at a position visible to the driver of the vehicle, and the acquired data is data that changes according to the movement of the vehicle. This effect is remarkable because the time during which the user can visually recognize the screen is very short compared to the time during which the driver is visually recognizing the front of the vehicle.
(11) As the meter display, a plurality of meters may be provided within the meter display area.
In this way, a plurality of meters can be visually recognized only by looking at the inside of the meter display area. Therefore, for example, the amount of states of more physical phenomena can be grasped at a glance.

(12) A screen having a plurality of meter display areas and a screen displaying one meter can be switched to be displayed, and the meter display displayed on the screen displaying the one meter and the plurality of meter display areas. While the outline display mode is the same as the meter display displayed in one of the meter display areas of the screen provided with, the detailed display mode may be different.

In this way, even when switching between a screen having a plurality of meter display areas and a screen displaying a single meter, the general display mode of the meter display is the same. You can tell at a glance that they are meters that display the same content. On the other hand, the detailed display mode of the meter display of both is different, so you can get different information by looking carefully. The detailed display mode may be a display mode that is more detailed than the general display mode, and the relationship between the two is relative. It is preferable to use a display mode that allows

(13) The screen may be arranged at a position visible to the driver of the vehicle, and the acquired data may be data that changes as the vehicle moves. In this way, in any of (1) to (12), the driver of the vehicle can select and display the necessary display contents of the meter display area, and many types of information can be displayed. It is possible to provide a control system that can display accurately.
(14) The function as the control system described in any one of (1) to (13) may be configured as a program to be implemented by a computer.

According to the present invention, it is possible to provide a control system or the like that allows a user to select and display a meter necessary for the user, and that can accurately display many types of information.

The priority of each function is set in order of radar wave warning function, radio warning function, and GPS warning function from the highest one.

The GPS alarm function is a process that is triggered by location information output from the GPS receiver 8 every second. In this process, the distance between the two is obtained from the latitude and longitude of , and when the metered distance reaches a predetermined approach distance (for example, within 1 km), the speaker 20 outputs an approach warning sound to that effect. When a screen other than the map screen is currently being displayed as the information display function (including the OFF screen), the process of outputting the sound is performed in this way. On the other hand, when the map screen is currently displayed as the information display function, in addition to audio output, as shown in the order of FIGS. A warning window that draws a schematic diagram of approach warning or an image based on photographic data or the like is superimposed on the map displayed on the map display portion of the map screen (in front) and drawn as an animation. That is, FIG. 9A shows a state in which the distance between the two is not yet within 1 km, and the map is displayed in the map display portion of the map screen, but the warning window is not displayed. When the distance between the two is within 1 km, as shown in FIG. 9(b), the right edge of the alarm window is gradually shifted from the upper left to the lower right of the map display until the right end is slightly right of the horizontal center of the map display. To display by increasing the brightness of the display while enlarging the size of the alarm window. The gradual increase in display brightness is illustrated as a change from FIG. 9(a) to FIG. 9(b). Regarding the size of the window, the display processing is the same as the drawing processing in the order of FIGS. 11A, 11B, and 11C described later. As for the animation, the object representing the shape of the target displayed inside the warning window is rotated, and the letters "WARNING" prepared for each target are displayed in order from the leftmost letter to the right in front of it. I do. A mini-radar is displayed on the upper right side of the map display part, superimposed on the map (on the front side). The mini radar is a circular window with a diameter of about a little less than 1/4 in the left and right direction of the screen, and is displayed at the upper right position of the map display section. The mini-radar displays a triangular own vehicle position object in the center of the circle, and draws the position of the target from the current position as a circular object in the circle. The radius of the circle corresponds to a distance of 1 km. In the examples of FIGS. 9B and 9C, the current position and the position of the H system, which is the target, are displayed. Then, the distance from the current position to the target is displayed within this circle. In Figures 9(b) and (c), the distance from the current position to the target is 580m, 500m in Figure 10(a), and 480m in Figure 10(b). The alarm window is erased (FIG. 10(c)). As shown in FIGS. 9(c), 10(a), and 10(b) in order, the process of gradually changing the animation to the actual image when the distance to the target becomes 500 m or less. When the distance between the current position and the target becomes 0, it is determined that the object has passed, and the alarm window displaying the actual image is faded out as shown in FIG. 10(c). is deleted. Note that the photographed image is actual photograph data obtained by photographing the position of the target.

These targets include drowsy driving accident points, radar, H system, LH system, speed limit switching points, control areas, inspection areas, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignorance suppression systems. , police station, accident-prone area, vehicle-targeted area, sharp/continuous curve (highway), junction/junction point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), highway oasis (highway), smart interchange (highway), gas station in PA/SA (highway), tunnel (highway), highway radio reception area (highway), prefectural border announcement, road There are a station, a view point parking, etc., and the type information of these targets, the latitude and longitude information indicating the position thereof, the data of the schematic diagram or the photograph displayed on the display unit 5, and the audio data are associated with each other and stored in the database 19. These are referred to and an approach warning is issued.

The radar wave warning function detects a signal corresponding to a frequency band microwave (radar wave) emitted from a speed measuring device (mobile radar, etc. (hereinafter simply referred to as "radar")) by the microwave receiver 4. This is an alarm function for displaying an alarm screen on the display unit 5 and outputting an alarm sound from the speaker 20 when an alarm is detected. For example, when microwaves in the frequency band of microwaves emitted by radar are detected by the microwave receiver 4, the voice data stored in the database 19 is read out and a voice saying "Radar. Be careful of speed" is output from the speaker 20. Output. The alarm lamp 6 is turned on during voice output. When a screen other than the map screen is currently being displayed as the information display function (including the OFF screen), the process of outputting the sound is performed in this manner. On the other hand, when the map screen is currently displayed as the information display function, in addition to the voice output, as shown in the order of FIGS. An alarm window that draws an image based on a schematic diagram of a radar wave alarm or photographic data is superimposed on (in front of) the map displayed on the map display portion of the map screen and drawn as an animation. That is, FIG. 11(a) shows a state in which no radar wave is received by the microwave receiver 4, in which the map is displayed in the map display portion of the map screen, but the warning window is not displayed. . When a radar wave is received by the microwave receiver 4, as shown in the order of FIGS. The display brightness is increased while enlarging the size of the alarm window to a position slightly to the right of the center in the left-right direction. As the animation, an object indicating the shape of the target displayed inside the warning window is rotated, and the characters prepared in advance such as "WARNING" are displayed in order from the leftmost character to the right in front of the object. After performing this display for a certain period of time (for example, 10 seconds), as shown in the order of FIGS. 13A, 13B, and 13C, when the radar wave is no longer received, the warning window displaying the photographic image is faded out as shown in FIGS.

The radio alarm function is a function of issuing an alarm so as not to hinder the movement of the emergency vehicle or the like when the radio receiver 15 receives the radio wave emitted by the emergency vehicle or the like. In the radio alarm function, control radio, car location radio, digital radio, special radio, station active radio, police phone, police activity radio, tow radio, helicopter radio, fire helicopter radio, firefighting radio, emergency radio, expressway radio , security radio frequencies, etc., and when a radio signal is received at the scanned frequency, a schematic diagram indicating that the radio signal corresponding to the frequency stored in the database 19 for each radio type has been received is displayed as an alarm screen. While displaying on the display unit 5, the voice data stored in the database 19 for each wireless type is read out, and an alarm sound indicating the wireless type is output from the speaker 20. FIG. For example, when receiving a crackdown radio, it outputs a voice such as "This is crackdown radio. Be careful of speed." The alarm lamp 6 is turned on during voice output. When a screen other than the map screen is currently being displayed as the information display function (including the OFF screen), the process of outputting the sound is performed in this manner. On the other hand, when the map screen is currently being displayed as the information display function, for example, the display indicating the wireless alarm is displayed as part of the changes shown in FIGS. Other than that, perform the same processing as the radar wave warning function.

On this screen, when a touch on the "automatic item" button on the right end of the upper row is detected, the automatic item setting screen 1/2 shown in FIG. 16(a) is displayed.

This auto item setting screen 1/2 has a screen title display portion of "auto item 1/2" at the top, and an "EXIT" button, a "BACK" button, a blank space, and a right arrow button at the bottom in order from left to right. It has a button display. A switching screen selection button display portion is provided between the screen title portion and the control button display portion. The switching screen selection button display portion displays a total of seven toggle buttons, including four buttons on the first line and three buttons on the second line. When a touch on the right arrow button provided in the control button display unit is detected, the auto item setting screen 2/2 shown in FIG. The automatic item setting screen 2/2 shown in c) is displayed. The automatic item setting screen 2/2 also has the same configuration as the automatic item setting screen 1/1, and displays a total of six toggle buttons, including four buttons on the first line and two buttons on the second line. The auto item setting screen 2/2 in the OBD2 connected state and the OBD2 unconnected state is the same except that in the OBD2 unconnected state, the fuel consumption screen and the OBD data screen, which are not subject to switching display, are grayed out and cannot be selectively switched. is. An example of the OBD2 connection state will be described below. In the control button display section at the bottom of the auto item setting screen 2/2, the right arrow button that was displayed on the auto item setting screen 1/1 is blank, and the blank on the auto item setting screen 1/1 is now blank. Show the left arrow button. When a touch on the left arrow button is detected, the automatic item setting screen 1/2 shown in FIG. 16(a) is displayed. As described above, the automatic item setting screen 1/2 shown in FIG. 16A and the automatic item setting screen 2/2 shown in FIG. It is possible to switch between them (page switching is possible), and a toggle button is displayed for whether or not to switch display for 13 items in total between the automatic item setting screen 1/2 and the automatic item setting screen 2/2. It will be done. Note that when a touch on the "EXIT" button is detected, the process returns to the process before a touch on the setting button of the remote control 17 or the switch section 3 is detected. Further, when a touch on the "BACK" button is detected, the screen returns to the standby screen setting screen of FIG. 15B, which is the screen displayed one before. It should be noted that the processing when a button on the control button display portion is touched is the same processing in other drawings of the present embodiment.

In the auto item setting screen 1/2 of FIG. 16(a), a "Clock" button for setting whether or not to switch display to the clock screen is set in the first row and the first column, and a "Clock" button in the first row and the second column. "Speed" button for setting whether or not the speed screen is subject to switching display, "Eco Drive" for setting whether or not the eco drive screen is subject to switching display in the 1st row and 3rd column button, 1st row, 4th column "Acceleration" button for setting whether to switch display to the acceleration screen, 2nd row, 1st column to set whether to switch display to the tilt screen "Tilt" button for switching display, "Tide information" button for setting whether to switch the tide information screen on the 2nd row and 2nd column, 2nd row and 3rd column for switching display of the graph screen. It has a "graph" button for setting whether to target or not. In the automatic item setting screen 2/2 of FIG. 16(b), a "preset A" button for setting whether or not to switch display to the preset A screen is set in the first row and the first column, and a "preset A" button in the first row and the second column. "Preset B" button for setting whether or not the preset A screen is to be switched and displayed, and for setting whether or not the preset C screen is to be switched and displayed at the 1st row and 3rd column. "Preset C" button, 1st row 4th column "Positioning information" button for setting whether to switch display of the positioning information screen, 2nd row 1st column for switching display of the fuel consumption screen A "fuel consumption" button for setting whether or not to switch display is provided, and an "OBD data" button for setting whether or not the OBD data screen is to be switched and displayed is provided in the second row and second column. Button names are displayed on the surfaces of these buttons. The button name of each button indicates the characters enclosed in square brackets in the above text. For example, for a "clock" button, "clock" in square brackets is displayed as the button name. Each button is a rectangular button of the same size with the long side extending in the horizontal direction surrounding these characters. A space of a predetermined width is provided between each button to prevent erroneous touches.

At the left end of each button, an indicator portion showing an image of a strip-shaped LED lamp that lights green with a width thinner than the width of the button is provided from the top end to the bottom end of each button. This indicator takes a lighting state and a non-lighting state. When a touch to the position of any button on the touch panel of the display unit 5 is detected, the lighting state of the indicator of the touched button is reversed. That is, if it is in the lighting state, it is in the non-lighting state, and if it is in the non-lighting state, it is in the lighting state. When the indicator is lit, the screen corresponding to the button is set as the switching display target, and when the indicator is unlit, the screen corresponding to the button is stored in the database 19 as setting not to be the switching display target. . This memory processing is performed when there is a change in the lighting state of the indicator. For example, when the pressing of the "EXIT" button is detected and the display of the AUTO screen is selected as shown in FIG. Only the screens stored in the database 19 are switched every one minute. In the following description, it is assumed that the display of the AUTO screen is selected as shown in FIG. 3(b).

FIGS. 16(a) and 16(b) show examples in which the indicators of all the buttons are in a lighting state. This state is the default state described above. In this state, when a touch on the "EXIT" button is detected, all screens are subject to switching display. That is, the clock screen, speed screen, eco-driving screen, acceleration screen, tilt screen, tide information screen, graph screen, preset A screen, preset B screen, preset C screen, positioning information screen, fuel consumption screen, and OBD data screen are displayed in this order. The format screen is switched and displayed every minute. After displaying the OBD data screen for one minute, the screen returns to the clock screen, and the display is switched in the same manner thereafter.

FIG. 17A shows an example in which the indicator of the "clock" button on the automatic item setting screen 1/2 is in a non-lighting state and the indicators of the other buttons are in a lighting state. Assume that the indicators of all the buttons of the automatic item setting screen 2/2 are in a lighting state as shown in FIG. 16(b). In this state, when a touch on the "EXIT" button is detected, all screens except the clock screen are subject to switching display. That is, the speed screen, the eco-driving screen, the acceleration screen, the tilt screen, the tide information screen, the graph screen, the preset A screen, the preset B screen, the preset C screen, the positioning information screen, the fuel consumption screen, and the OBD data screen, in this order. is displayed alternately every minute. After the OBD data screen is displayed for one minute, the screen returns to the speed screen, and the display is switched in the same way thereafter. The clock is displayed in the upper right corner of the screen for each format, so users who do not think it is necessary to switch the display can touch each button to set the indicator state. , the clock screen can be switched and not displayed.

FIG. 17B shows an example in which the indicators of the "clock" button and the "tide information" button are in a non-lighting state, and the indicators of the other buttons are in a lighting state. Assume that the indicators of all the buttons of the automatic item setting screen 2/2 are in a lighting state as shown in FIG. 16(b). In this state, when a touch to the "EXIT" button is detected, all screens other than the clock screen and the tide information screen are subject to switching display. That is, the speed screen, eco-driving screen, acceleration screen, tilt screen, graph screen, preset A screen, preset B screen, preset C screen, positioning information screen, fuel consumption screen, and OBD data screen are displayed every minute in this order. switch to display. After the OBD data screen is displayed for one minute, the screen returns to the speed screen, and the display is switched in the same way thereafter. The clock screen and tide information screen depend only on the date and time, and do not change with the running of the vehicle. Therefore, a user who wants to know the current state that changes as the vehicle travels switches between the clock screen and the tide information screen by touching each button to set such an indicator state. It is possible to prevent the display from being displayed, and to switch and display only the screen of the format that displays the current state that changes as the vehicle travels.

FIG. 17(c) is an example in which indicators of all seven buttons on the automatic item setting screen 1/2 are in a non-lighting state. In the auto item setting screen 2/2, as shown in FIG. 18(a), the indicators of the "preset A" button, the "preset B" button, and the "preset C" button are lit, and the "positioning information" button, Assume that the indicators of the "fuel consumption" button and the "OBD data" button are in a non-lighting state. In this state, when a touch on the "EXIT" button is detected, the preset A screen, the preset B screen, and the preset C screen are switched and displayed every minute in the order of each format screen. After displaying the preset C screen for one minute, the screen returns to the preset A screen, and the display is switched in the same manner thereafter. In this way, the user can repeatedly display three types of triple meters preset by the user, and can prevent screens of other formats from being displayed. By reducing the number of screens to be selected in this way, the time required for one repetition display (in this example, the time required for one repetition display is 3 minutes) can be shortened. Also, for example, if the meters on these three preset screens are all set to different types of meters, a total of nine types of meters can be checked in three minutes.

Next, the processing for setting the type of information display to be displayed on the preset A screen, preset B screen, and preset C screen will be described. This setting process is started by a screen transition caused by detection of the following operation. As described above, the setting screen shown in FIG. 15 is displayed when it is detected that the setting button of the remote controller 17 or the switch section 3 is pressed in any screen display state. In this state, when a touch on the "standby" button on the left end of the upper row is detected, the standby screen setting screen shown in FIG. 15(b) is displayed. In this screen, when a touch to the "preset A" button, "preset B" button, or "preset C" button on the second line is detected, a preset information setting screen relating to the preset is displayed. Here, an example in which the "preset A" button is touched will be described. The same processing is performed when the "preset B" button or the "preset C" button is touched.

When the "preset A" button is touched, a preset information setting screen as shown in FIG. 19(a) is displayed. Similar to the auto item setting screen, the preset information setting screen has a screen title display section "Preset A" at the top, and a control button display section with an "EXIT" button and a "BACK" button in order from left to right at the bottom. , Between the screen title and the control button display, three information display type settings are arranged at positions corresponding to the left position meter display area, middle position meter display area, and right position meter display area in Fig. 7(a). An information display type setting button display section having buttons is provided. That is, the information display type setting button display section includes a left position information display type setting button for setting the type of information display to be displayed in the left position meter display area arranged at the lower left position, and a middle position meter display arranged at the upper center position. Middle position information display type setting button for setting the type of information display to be displayed in the area, right position information display type setting for setting the type of information display to be displayed in the right meter display area placed in the lower right position Equipped with a button. A character string indicating the type of information display currently set is displayed on each button. As for the type of information display, in the default state, the preset A screen has the left position meter display area as the clock, the middle position meter display area as the vehicle speed, and the right position meter display area as eco-driving, as shown in Fig. 19(a). have set. An example in which the preset A screen is displayed in this state is the display example shown in FIG. 7(a). That is, according to the setting of each information display type setting button, the clock is displayed in the left position meter display area, the vehicle speed is displayed in the middle position meter display area, and the eco-driving information is displayed in the right position meter display area.

The default settings for the preset B screen are the left position meter display area for the clock, the middle position meter display area for acceleration, and the right position meter display area for vehicle speed. An example display is shown in FIG. 7B. The default settings for the preset C screen are compass for the left position meter display area, tilt for the middle position meter display area, and tide information for the right position meter display area, and an example display is shown in FIG.

In the display state of FIG. 19(a), the process of changing the type of information display displayed in the middle position meter display area from vehicle speed to acceleration as shown in FIG. 19(b) will be described. The same processing is performed to change the type of information display for the left position meter display area and the right position meter display area.

When a touch on the middle position information display type setting button is detected, an information display type selection screen shown in FIG. 20(a) is displayed. The information display type selection screen has a control button display section having a return button, a blank space, an up arrow button, and a down arrow button on the right side in the vertical direction, and four information display type buttons on the left side thereof in the vertical direction. When a touch on the down arrow button is detected, the four information display type buttons are scrolled upward.

As shown in FIG. 20(a), the type of information display currently set second from the top is first displayed. Since the setting of the middle position information display type setting button in FIG. 19(a) is "vehicle speed", the second information display type button from the top is displayed as "vehicle speed", and this information display type button is highlighted. It is displayed to indicate that it is in the current selection state.

In this state, when a touch on the down arrow button is detected, the display is as shown in FIG. 19(b). That is, the information display type button displayed second from the top is moved to the top, the information display type button displayed third from the top is moved to the second from the top, and the fourth from the top ( The information display type button displayed at the bottom) is moved to the third from the top, and the information display type buttons newly set in the following order are displayed at the fourth from the top (bottom). As a result, in this example, as shown in FIG. 20(b), the vehicle speed information display type button has moved to the top. FIG. 20(c) shows a display example when the downward arrow button is touched three more times in this state. FIG. 21(a) shows a display example when the downward arrow button is touched three more times in the state of FIG. 20(c). FIG. 21(b) shows a display example when the down arrow button is touched three more times from the state shown in FIG. 21(a). FIG. 21(c) shows a display example when the downward arrow button is touched three more times from the state shown in FIG. 21(b). FIG. 22(a) shows a display example when the downward arrow button is touched three times from the state shown in FIG. 21(c). FIG. 22B shows a display example when the downward arrow button is touched three times from the state shown in FIG. 22A. FIG. 22(c) is a display example when the down arrow button is touched several more times in the state of FIG. 22(b). The display state of FIG. 22(c) is the same as the display state of FIG. 20(a). By cyclically scrolling the information display type buttons in this manner, options for the types of information display that can be set are presented.

As shown in FIGS. 20(a) and 20(b), when a touch to the position of the information display type button of acceleration is detected as the information display type button, the touched button of acceleration is highlighted. While moving to the information display type button, the middle position information display type setting of the preset A of the database 19 is changed to "acceleration" and stored. In this state, when a touch to the return button is detected, the display on the middle position information display type setting button is changed to this "acceleration" as shown in FIG. 19(b). With this setting, when the preset A screen is displayed, as shown in FIG. 23, the middle position meter becomes the "acceleration" meter.

In this manner, the user can set the type of information display to be displayed in each meter display area on each preset screen, and display the information.

In the case of AUTO display setting, if a preset screen is selected as a switching display target, the preset screen set by the user in this way can be a switching display target.
Next, major types of meters that can be selected on the information display type selection screen will be described.

FIG. 29(c) is an example of the information display of the intake manifold gauge. FIG. 29(d) is an example of information display of the boost gauge. FIG. 30 is an example of information display of the tachometer. In addition, each figure is a figure when each information display is selected as what is made into a middle position meter display area. Although the positions of the middle-position meters are shown as rectangles, the display contents within the circular frames are the same when information is displayed in the right-position meter display area and the left-position meter display area.
The information display of the clock is a predetermined display, and as shown in FIG. 24(a), it is an analog needle type clock that displays the time.

The information display of the vehicle speed is a meter display, and as shown in FIG. 24(b), the vehicle speed obtained from the GPS receiver 8 is displayed with an analog meter and numbers. The analog meter draws a needle in the radial direction from the center of the circular meter display area toward the circumference side, and the needle points in the 7 o'clock direction when the speed is 0 km/h, and the speed is 160 km/h. When the speed is increased, the direction of the pointer is changed clockwise so that it points to the 3 o'clock direction. The numbers are displayed together with the units of km/h in a fan-shaped area approximately ranging from 3 o'clock to 7 o'clock. The background color of the analog meter is gray, and the background color of the numbers is black.

The eco-driving information display is a meter display, and as shown in FIG. 24(c), rapid acceleration is displayed on the upper side, rapid deceleration is displayed on the right side, idling is displayed on the lower side, and economic speed is displayed on the left side as a radar chart. Each point is displayed with an upper limit of 100 points (displayed as 100pt) and a lower limit of 0pt. The initial value of each point is 70pt, and points are deducted when the acceleration output from the acceleration sensor 27 and the speed output from the GPS receiver 8 are judged to be non-eco-driving. Points are added when the output state is set, and the numerical value of each point and a graph plotting the numerical value on a radar chart are displayed.

The eco-driving information display has the same general display mode as the radar chart display portion of the eco-driving screen illustrated in FIG. 5B, but has a different detailed display mode.

As shown in FIG. 24(d), the acceleration information display has a configuration in which a plurality of meters are provided in the meter display area as meter display. The first meter is a circular shape whose center is located slightly above and to the left of the center position of the circle in the meter display area and whose center is about half the radius of the circle, whose diameter is the radius of the meter display area. is drawn in the area of The second meter is a circle whose center is located slightly to the right of the center position of the circle in the meter display area and whose center is about half the radius of the circle, whose diameter is the radius of the meter display area. is drawn in the area of The first meter on the left displays lateral acceleration and the second meter on the right displays longitudinal acceleration. Acceleration in the front-back direction and acceleration in the left-right direction are displayed numerically in a fan-shaped area from 3 o'clock to 7 o'clock similar to the vehicle speed information display in FIG. 24(b). This figure is underlined. A continuous line is drawn from the left end of the underline of the horizontal acceleration numerical value toward the outer edge of the first meter. Similarly, a continuous line is drawn from the left end of the underline of the longitudinal acceleration numerical value toward the outer edge of the second meter. With this line, it is easy to understand which numerical value indicates which meter value.
An explanatory diagram of the first meter is shown on the right side of FIG. 31, and an explanatory diagram of the second meter is shown on the left side of FIG. Both the first meter and the second meter have long and short hands.

The first meter, as shown on the right side of FIG. 31, uses the 12 o'clock direction as the base point, moves the long hand so that 0.5 G is the 3 o'clock direction, and -0.5 G is the 9 o'clock direction. . Move the long hand to a position equivalent to 0.75G maximum and -0.75G minimum. Hold if it exceeds. The short hand expresses changes in acceleration by rotation at 0.03G/360 degrees (one turn). That is, it makes one rotation from the base point with an acceleration of 0.03G. Rotate clockwise as positive acceleration.

The second meter, as shown on the left side of FIG. 31, uses the 3 o'clock direction as the base point, and moves the minute hand so that 0.5 G is the 3 o'clock direction and -0.5 G is the 9 o'clock direction. . Move the long hand to a position equivalent to 0.75G maximum and -0.75G minimum. Hold if it exceeds. The short hand expresses changes in acceleration by rotation at 0.03G/360 degrees (one turn). That is, it makes one rotation from the base point with an acceleration of 0.03G. Rotate clockwise as positive acceleration.

In this way, by shifting the reference point positions of the first meter and the second meter by 90 degrees, it is possible to easily grasp in which direction the meter indicates the acceleration. Further, by shifting the reference points of the first meter and the second meter by 90 degrees and using the same scale, it is possible to easily compare the magnitude of acceleration in the lateral direction and the magnitude of acceleration in the longitudinal direction. can.

Furthermore, since the short hand makes one rotation from the base point with an acceleration of 0.03 G, a minute change in acceleration can be grasped as the angular velocity of the rotation of the hand. In addition, it is possible to grasp minute changes in acceleration from the angular velocity of the rotation of the short hand, and at the same time to grasp the absolute acceleration from the absolute value of the acceleration pointed by the long hand. The scale of the long hand has a maximum value of 0.75 G, which is the maximum value of acceleration that can occur during normal driving, and the movable range is plus or minus 135 degrees from the base point. can be absolutely specified.

For example, while a large acceleration of about 0.3 G occurs when the vehicle starts or stops, there is only a slight change of 0.1 G or less during running. By providing a long hand and a short hand like the first meter and the second meter, the situation of both can be accurately grasped.

The tilt information display is a meter display, and as shown in FIG. 25(a), the tilt of the vehicle at 30 degrees in the front, rear, left, and right directions is displayed by the motion of a sphere. This tilt information display is substantially the same (actually similar) to the display of the tilt image display section on the tilt screen shown in FIG. is smaller), but is different in that it has a more detailed display configuration. That is, as a detailed display, as shown in FIG. The top surface of the lower hemisphere (boundary surface between the upper and lower hemispheres (equator A white disk with the same radius as the radius of the hemisphere is drawn on the plane passing through )), and an image of a 3D object of a car placed on it is displayed. The 3D object of this automobile is rotated and displayed on the upper surface of this lower hemisphere according to the current direction of travel detected by the geomagnetic sensor 28 . The vertical back direction of the screen shown in FIG. 32 is north, the vertical front direction is south, the horizontal right direction of the screen is east, and the horizontal left direction of the screen is west. The car in the ball is displayed with the tail lamp side parallel to the plane of the screen when the car is heading due north, so that the entire tail lamp side can be seen. As shown in FIG. 32, red markers are attached in vertical bands at positions indicating the direction of travel around the disk. In the state shown in FIG. 32, the vehicle faces south-southeast, the front of the car is displayed facing slightly to the right, and the marker is also displayed at a slightly right position. Then, this display is continued for 3 seconds after the output value of the acceleration in the lateral direction (rightward or leftward) of the vehicle of the acceleration sensor 7 becomes less than 0.1 G, and the original FIG. display. In this way, when the turning motion is detected based on the lateral G of the car above a certain level, the car inside the ball becomes visible for a certain period of time, and the turning motion is expressed. In this way, the turning situation can be confirmed by the detailed display.

The information display of the tide information is a predetermined display because it displays the tide level calculated based on the data rather than the measured quantity, and the tide information shown in FIG. Although the content displayed on the screen is displayed, the outline display mode is also different. Specifically, first, as shown in FIG. 33(a), tide information is displayed, which displays the name of the place such as the tide station closest to the current position, the age of the moon on the current date, and the name of the tide. Then, after 10 seconds have passed, the information display of tide information indicating the time and level of the first low tide and the time and level of the first high tide of the day is displayed as shown in FIG. 33(b). After 10 seconds have elapsed since the tide information meter shown in FIG. 33(b) was displayed, the tide is displayed as shown in FIG. Information information display. When 10 seconds have elapsed since the tide information shown in FIG. 33(c) was displayed, the display returns to the tide information shown in FIG. 33(a). Then, the information display of the tide information on the screen of FIG. 33(a) is displayed again for 10 seconds, and then switched to the information display of the tide information on the screen of FIG. 33(b). switch.

The information display of the satellite information is a predetermined display because the amount is not displayed. As shown in FIG. The grid is displayed with the left direction as west. The grid consists of three concentric circles with different radii centered on the position of the vehicle, and lines that pass through the center position in the horizontal and vertical directions (however, no lines are drawn within the concentric circle with the smallest radius). . A circular satellite object is drawn at a position corresponding to the position of the satellite acquired by the GPS receiver 8 . After displaying for 3 seconds in this state, the satellite numbers are displayed one satellite at a time. That is, as shown in FIG. 34(a), all acquired satellites are displayed at their corresponding positions, and after 3 seconds, the first satellite number is displayed as shown in FIG. 34(b). . In this example, "12" is displayed. After displaying for 3 seconds in this state, the next satellite number is displayed as shown in FIG. 34(c). In this example, "14" is displayed. After displaying for 3 seconds in this state, the next satellite number is similarly displayed, and after displaying for 3 seconds in this state, the next satellite number is displayed. When the display of all satellite numbers is completed in the same way, the operation of returning to the original display as shown in FIG. 34(a) is repeated.

The information display of the compass is a predetermined display because the amount is not displayed, and as shown in FIG. In the example of FIG. 25(d), the right rear is north with respect to the traveling direction of the car. North is indicated by "N", South by "S", East by "E" and West by "W".

Information display of instantaneous fuel consumption in Fig. 26(a), information display of average fuel consumption in Fig. 26(b), information display of average fuel consumption on ordinary roads in Fig. 26(c), information display of average fuel consumption on highways in Fig. 26(d) 27(a) current fuel consumption information display, FIG. 27(b) lifetime fuel consumption information display, FIG. 28(a) engine coolant temperature information display, FIG. 28(b) intake air temperature information display, The outside air temperature information display in FIG. 28(c) and the battery voltage information display in FIG. 28(d) both have an analog needle type meter display section on the upper side and a numeric display section on the lower side. Then, in the analog needle type meter display section, the needle is moved to point to the position corresponding to the value in a manner simulating an analog needle type meter, and the numerical value is displayed in the numerical display section.

The instantaneous fuel consumption information display is a meter display, and as shown in FIG. 26(a), the instantaneous fuel consumption is displayed in the range of 0.0 to 99.9 km/l. The needle is 5km/l at the scale lower limit (45° left), 50km/l at the scale upper limit (45° right), 0km/l at the lowest point (53° left), and 100km/l at the highest point (53° right). and The same applies to all other fuel consumption needles in FIGS. 26(a) to (d) and FIGS. 27(a) and (b). An indicator is provided on the left side of the numerical value displayed on the numerical display unit. This indicator is an index that shows whether fuel efficiency is good, and is red when 0-5 km/l, interpolates between red and yellow when 5-10 km/l, and yellow-green when 10-30 km/l. Complements the gap, and displays a green indicator (circle imitating a lamp) when the speed is 30kmkm/l or more.

As described above, the radar detector of the present embodiment is a control system for performing meter display control based on the acquired data. At least one meter display area on the screen is characterized by displaying a type of meter selected by the user. By doing so, the user can select the meter necessary for the user and display it on the screen. A control system that has a plurality of meter display areas on one screen and can display a plurality of types of information on the screen by selecting the meters that are necessary for the user. etc. can be provided. In particular, the screen is arranged at a position visible to the driver of the vehicle, and the acquired data is data that changes according to the movement of the vehicle. While driving a vehicle, it is difficult to switch screens or select the type of meter display. It can be selected and displayed while driving.

The acquired data is acquired from the vehicle via various sensors and the OBD2 connector shown in FIGS. Acquisition of data is triggered by a predetermined event such as when there is a change in data or at a predetermined time interval.

The meter display is, for example, a display indicating a weighing scale as shown in each figure. As the weighing scale, for example, an image of a tool, machine, or device for weighing may be displayed. When there is a change in the acquired data, the meter display is configured to be updated to show the change. For example, if there is a change in the acquired data, it may be updated and displayed at all times. It may be configured such that the update display is performed and the update display is not performed when there is a change but the change does not follow a predetermined pattern. Alternatively, regardless of data update, the display may be updated according to a predetermined rule, such as at predetermined time intervals. A particularly good configuration is to update and display the meter display at a timing that allows the user to recognize that the meter display reflects the current situation. The timing at which the user can recognize that the meter display reflects the current situation may vary depending on the type of data displayed on the meter.

For example, a configuration may be adopted in which information regarding these various current conditions is displayed on a meter based on data regarding current conditions acquired from various sensors and other devices. Even if the types of meters increase in this way, a desired meter can be selected and displayed without preparing a screen for each type of meter and without increasing the number of screens. In addition, although a plurality of meters are displayed on one screen, at least one meter display area on the screen displays the type of meter selected by the user. It is possible to display a meter that can be used, and it is possible to grasp a lot of information accurately.

A plurality of types of meter display are provided, and control is performed to display the type of meter display selected by the user. As a configuration for displaying the type of meter display selected by the user, information for specifying the type of meter display selected by the user is stored in storage means such as the non-volatile memory of the control unit 18 and the database 19. , the specified type of meter display is performed based on the information for specifying the type of meter display selected by the user stored in the storage means. For example, if the meter is of a type that the user can perceive changes in milliseconds, it should be updated in milliseconds. For example, if the meter is of a type that allows the user to perceive changes in units of seconds, it should be updated in units of seconds. For example, if the meter is of a type that allows the user to perceive changes on a minute-by-minute basis, it should be updated on a minute-by-minute basis. For example, if the meter is of a type that allows the user to perceive a change in units of one hour, the meter should be updated in units of one hour. For example, if the meter is of a type that allows the user to perceive a change on a daily basis, it may be updated on a daily basis.

Selection of the type of meter display by the user is configured such that options for selecting any meter display are presented and the user is made to select from the presented options. The options are presented on the display unit 5, and the options are displayed on the display unit 5, which is on the same screen as the screen having a plurality of meter display areas. In other words, the configuration is such that the options are displayed by switching from the state in which the screen including a plurality of meter display areas is displayed to the state in which the screen for displaying the options is displayed.

As the screen, a display unit 5 having a screen such as a dot matrix display whose display contents can be changed is used. In this embodiment, the screen is, for example, the entire display area of the display unit, but it may be a part of it. The plurality of meter display areas may be arranged, for example, so that the respective meter areas do not overlap, but in the present embodiment they are arranged so as to partially overlap. In this configuration, in the present embodiment, the amount to be metered is visually displayed in the non-overlapping portion. Alternatively, for example, the overlapping portion may be translucent so that both the lower side (back side) and the upper side (front side) can be visually recognized.

Each meter display area is configured to display a type of meter selected by the user. By doing so, the user can select which type of meter display is to be displayed in which meter display area on the screen, and the desired type of meter can be displayed in the desired arrangement. As a configuration for allowing the user to select the type of meter display for each meter display area, in the present embodiment, the meter display area to be selected is first selected, and which type of meter display is to be displayed for the selected meter display area. However, it is also possible to first select which type of meter display is to be performed, and then select in which meter display area the selected type of meter display is to be performed. As for the selection of the meter display area, as in the present embodiment, it is preferable to present options for selecting which meter display area and allow the user to select from the presented options. The options may be presented by, for example, the display unit 5 as in the present embodiment, and may be presented by displaying the options on the same screen as the screen having a plurality of meter display areas. As in the present embodiment, a screen having a plurality of meter display areas may be switched to a display screen for options to display the options.

In this embodiment, control is performed to display a predetermined display other than the meter display, and in each meter display area, a type of meter display selected by the user or a predetermined display selected by the user is performed.

Therefore, the user can visually recognize the contents of the selected predetermined display other than the meter display by simply looking at the screen with the intention of viewing the meter display. In this way, the contents of the selected predetermined display other than the meter display can be viewed with the same movement of the line of sight as when viewing the meter display. For example, the user selects to display a first type of meter display in the first meter display area, and selects to display a predetermined display in a second meter display area different from the first meter display area. In this case, by moving the line of sight to the first meter display area and the second meter display area of one screen, the first type of meter display and the predetermined display can be visually recognized naturally. In particular, as in the present embodiment, the screen is arranged at a position where the driver of the vehicle can see it, and the acquired data is data that changes according to the movement of the vehicle. If you shift your line of sight to the screen in order to check the data that changes as the vehicle moves, you will be able to instantly and naturally see the predetermined display other than the meter display.

The predetermined display is a display that is not a meter display, and may be a display that is not a scale that measures the amount of the state of a physical phenomenon, such as a clock showing the time in this embodiment, or a display of the tide of the day. .

In this way, the weighed amount and the non-weighed amount can be confirmed on one screen at the same time. Moreover, the non-measured quantity is displayed in the meter display area, and the user-selected quantity can be displayed and visually recognized in the same manner as the meter display.

In this embodiment, different types of predetermined displays that can be displayed in the meter display area are provided, and a type of predetermined display selected from the plurality of predetermined display types is displayed in the meter display area. By doing so, the user can cause the type of predetermined display selected from among the different types of predetermined display to be displayed in the meter display area. Therefore, it is possible to select a predetermined display necessary for the user and display it on the screen, so that it is possible to provide a control system or the like capable of accurately displaying a plurality of types of information.

In this embodiment, the display content is switched according to a predetermined switching trigger as the predetermined display. Therefore, the display contents are switched in response to a predetermined switching trigger within the meter display area on the screen. Therefore, the content of the predetermined display is automatically switched within the meter display area without reselecting the type of the predetermined display each time. As a result, there is no difficulty in grasping which option corresponds to which predetermined display, and there is no need to take time to find a desired option from a large number of options.

The selectable meter display and the selectable predetermined display are displayed without distinction as selection items on a selection screen for selection by the user. Therefore, the user can select the meter display or the predetermined display without being conscious of it.
