Description

The present invention relates to a control system or the like that controls switching and displaying screens of different formats for displaying information on the current situation.

For example, in a control system that notifies an approach to a notification target such as a vehicle speed measuring device, the position information of the notification target is stored and retained, and the position of the own vehicle detected by GPS and the position of the notification target are a predetermined approach. Some issue an alarm when a relationship is established (for example, Patent Document 1 and the like).

In the case of a control system such as Patent Document 1, for example, when the detection target to be notified and the current position of the vehicle reach a set distance (for example, 1 km, 500 m, etc.), "500 m ahead, XX". (○○ outputs an audible alarm such as information for identifying the target (loop coil, etc.), or outputs and displays the information related to the display in text.

These control systems contribute to preventing the driver from unknowingly overspeeding, for example by notifying the driver of the approach to the vehicle speed measuring device. In particular, since the vehicle speed measuring device is generally installed in a place where the speed is likely to be exceeded, the driver can be alerted to the speed exceeding in a dangerous place. ..

In such a control system, when the vehicle is not close to the notification target such as a vehicle speed measuring device, a map screen around the current position is displayed, the acceleration applied to the vehicle is displayed, or a clock is displayed. , It has a function to display the current situation (Patent Documents 2 and 3).

The user has set to display one desired screen from screens of different formats for displaying information on these current situations, and displays the set screen. However, in recent years, the types of sensors and the like to be mounted have increased, and the data sensed on the vehicle side has been acquired from the connector connected to the vehicle to have a function of displaying various vehicle states. Screens in different formats are provided. Therefore, for example, a function of controlling to switch and display a large number of screens of these different formats in a predetermined order at a predetermined time interval can be considered.

However, when multiple screens of different formats are switched and displayed in a predetermined order at a predetermined time interval, screens in formats unnecessary for the user are displayed, and in many cases, the screen desired by the user is not displayed when desired. There is a problem of becoming. Further, in such a case, it is necessary to wait until the desired screen is switched and displayed.
Therefore, an object of the present invention is to provide a control system or the like capable of displaying a screen in a format required by the user.

In order to achieve the above-mentioned object, the control system according to the present invention is (1) a control system that controls to switch and display screens of different formats for displaying information on the current situation in a predetermined order at predetermined time intervals. The configuration is provided with a selection function for allowing the user to select a screen of the format to be the target of the switching display, and the screen of the format selected by the selection function is the target of the switching display.

In this way, the screen in the format required by the user can be displayed. For example, if a screen having a format unnecessary for the user is not selected as a screen having a format to be switched and displayed, a screen having a format unnecessary for the user will not be displayed. As a result, there is a high possibility that a screen of a desired format will be displayed when the screen desired by the user is desired. In addition, it is possible to shorten the time until the display is switched to the desired screen.

Information on the current status includes, for example, the current time, the current date, the current position, the current status of the person who visually recognizes the display of the system, and the current status of the place where the display unit displayed by the control system is installed. It is good to display information about the situation.

The current situation may be, for example, the situation at this moment, but may be the situation before the present to some extent. That is, for example, the past situation may be close to the present so that the user can recognize the current situation.
The predetermined order may be, for example, a predetermined fixed order, a user-set order, or a random order.

The predetermined time interval may be a predetermined fixed time interval such as a 1-minute interval, or may be a time interval that is variable according to the status of the acquired information. The predetermined time interval may be a time interval set by the user. Also, for example, the time from displaying the screen of the first format to switching to the display of the screen of the second format, and the display of the screen of the third format after displaying the screen of the second format. The time until switching may be the same time or different times.

As the switching display, for example, the screen area may be rewritten to another screen area. The screen may be, for example, the entire display area of the display means, but may be a part of the display area of the display means. At the time of rewriting, for example, a predetermined switching effect display is performed such that the screen area is gradually scrolled out and another screen area is scrolled in, or the screen area is faded in and faded out in the same manner. You may.

(2) It is preferable that the information regarding the current situation includes a plurality of different information acquired about the moving body, and the screens having the different formats are provided with a plurality of screens having a format for simultaneously displaying the different information. In this way, for example, a plurality of different information acquired about the moving body fluctuates with the movement of the moving body, and the fluctuations can be grasped at the same time by looking at a screen in a format for simultaneously displaying a plurality of different information. Further, since a plurality of screens having a format for simultaneously displaying a plurality of such different information are provided and control is performed for switching and displaying the information in a predetermined order at a predetermined time interval, for example, a large number of screens that fluctuate with the movement of the moving body. Information can be grasped in a short time.

The moving body may be, for example, a person or a vehicle. If it is a person, it is preferable to sense and acquire a physiological phenomenon such as a person's heartbeat and body temperature, or to sense and acquire the person's position and surrounding conditions. In the case of a vehicle, for example, the information generated by sensing by the vehicle itself may be acquired, or GPS, an acceleration sensor, a gyro sensor, etc. may be provided and acquired from these sensors or the like. ..

(3) The selection function may have a configuration in which screens of all formats that can be selected in the default state are targeted for the switching display, and screens of formats that are not targeted for the switching display are selected by the user's selection. By doing so, in the default state, the screens of all selectable formats are switched and displayed in a predetermined order at a predetermined time interval. This allows the user to know the screens of all formats that can be selected by the control system. Then, for example, after using the screen for a while in this state, by selecting a screen in a format that is unnecessary for oneself as a screen in a format that is not the target of switching display, only the screen in the format that is necessary for oneself can be switched and displayed. ..

(4) The selection function may be configured to display and select information representing a screen of each format, and to display information related to the information to be represented together with the screen of the format when the switching display is performed. In this way, it is possible to easily determine which screen should be selected when the selection function is executed by looking at the display of the information representing the screen of each format, and when the screen is switched and displayed, the format is displayed. You can confirm that the information that represents the screen of is set properly.

The information representing the screens of each format may be, for example, a character string of a name attached to each screen, a thumbnail screen in which each screen is reduced in size, an illustration or an icon indicating the contents of each screen, or the like.

(5) The display of the information representing the screen of the format in the case of switching display is performed in the screen of the format and is deleted when a predetermined time has elapsed after the switching, and the predetermined time until the erasing is performed. Is preferably configured to be shorter than a predetermined time from displaying the screen of the relevant format to switching to the screen of another format. In this way, the information representing the screen of the format is deleted in the screen of the format for a predetermined time. After that, the screen of the format is displayed in a state where the information representing the screen of the format is not displayed, and then the screen is switched to the screen of another format. Therefore, for example, when the screen is switched, what kind of information is displayed on the screen of the format can be grasped by the information representing the screen of the format, and the screen of the format can be grasped further. Since the information representing the above is deleted, the information about the current situation can be confirmed without being disturbed by the display of the information representing the screen of the format.

(6) As at least one of the screens of the format that can be selected, control is performed to switch and display a predetermined display area in the screen of the format at predetermined time intervals, and the screen of the format is changed to the screen of another format. The predetermined time interval of the switching display may be a time longer than the predetermined time interval of the switching display of the predetermined display area in the screen of the format. In this way, after the screen of the format is displayed, the switching display of the predetermined display area in the screen of the format is performed at a time interval shorter than the time interval for switching to the screen of another format. Therefore, there is no possibility of switching to a screen of another format without switching and displaying a predetermined display area in the screen of that format at all. Therefore, it is possible to visually recognize a large amount of information on the current situation in a short time by the switching display of the predetermined display area in the screen of the format and the switching display of the screen itself of the format.

(7) As at least one of the screens of the format that can be selected, a screen of a format that makes it possible to grasp the current situation by comparing the current situation with the past situation is provided, and another format is provided from the screen of the format. The predetermined time interval of the switching display to the screen may be configured as a time interval in which the current situation can be grasped by comparing the current situation with the past situation. In this way, the current situation and the past situation can be compared and visually recognized before the screen of the currently displayed format is switched to the screen of another format. As a format that enables the current situation to be grasped by comparing the current situation with the past situation, for example, a screen that displays a graph showing the current situation and the past situation together may be preferable.

(8) Event screen display switching function that switches and displays a screen that notifies the occurrence of a predetermined event when a predetermined event occurs while the function of switching and displaying screens of different formats in a predetermined order at a predetermined time interval is being executed. The screen of the same format as the screen for notifying the occurrence of the event may not be provided as the screen of the format that can be selected as the target of the switching display. By doing so, the screen having the same format as the screen notifying the event occurrence is not switched and displayed in a predetermined order at a predetermined time interval, so that the user can surely know the event occurrence. At the same time, the screens that are switched and displayed at predetermined time intervals in a predetermined order will not be erroneously recognized as an event occurrence screen.
(10) The function as a control system according to any one of (1) to (9) may be configured as a program to be realized by a computer.

According to the present invention, it is possible to provide a control system or the like capable of displaying a screen in a format required by the user.

Next, the process to be executed in response to the event that occurred during the execution of the information display function will be described. During the execution of the current information display function, processing to realize each function such as GPS alarm function, radar wave alarm function, wireless alarm function, etc. is executed according to the event that occurred, and when the processing of the function is completed, the original current information is executed. Return to the execution process of the display function. The priority of each function is set in the order of radar wave warning function, wireless warning function, and GPS warning function from the highest priority.

The GPS alarm function is a process executed by using the position information output from the GPS receiver 8 every second as a trigger, and is the latitude / longitude of the target stored in the database 19 and the current position detected by the GPS receiver 8. This is a process of obtaining the distance between the two from the latitude and longitude of the above, and when the obtained 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 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 the audio output, FIGS. 9 (a), (b), (c) and 10 (a), (b), and (c) are shown in this order. An animation drawing is performed by overlaying the warning window for drawing an image based on a schematic diagram of an approach warning or photographic data on the map displayed on the map display section of the map screen (front). 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 on the map display portion of the map screen, but the alarm 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 gradually moves from the upper left to the lower right of the map display to a position slightly to the right of the center of the map display in the left-right direction. Increase the size of the alarm window and increase the brightness of the display. The state of gradually increasing the brightness of the display is shown as a change from FIG. 9A to FIG. 9B. The size of the window is a display process similar to the drawing process in the order of FIGS. 11A, 11B, and 11C, which will be described later. As an animation, the object showing the shape of the target displayed inside the alarm window is rotated, and the characters stored in the database 19 for each target such as "WARNING" are displayed in order from the leftmost character to the right in front of it. Perform the process to make it. On the upper right side of the map display unit, a mini radar is displayed on top of the map (in front). The mini radar is a circular window with a diameter of about a quarter of the screen in the left-right direction, and is displayed at the upper right position of the map display unit. The mini radar displays a triangular own vehicle position object in the center of the circle, and draws the position of the target object as seen from the current position in the circle as a round object. The radius of the circle corresponds to a distance of 1 km. In the example of FIGS. 9B and 9C, the current position and the position of the target H system are displayed. Then, the distance from the current position to the target is displayed in this circle. In FIGS. 9 (b) and 9 (c), the distance from the current position to the target is 580 m, in FIG. 10 (a), 500 m, and in FIG. 10 (b), 480 m. When passing through, the process is opposite to that of the alarm window. The alarm window is cleared (FIG. 10 (c)). As shown in FIGS. 9 (c), 10 (a), and 10 (b), the process of gradually changing the animation into a live-action image when the distance to the target is 500 m or less. I do. When the distance between the current position and the target is considered to be 0, it is determined that the vehicle has passed, and the alarm window displaying the live-action image is faded out and the alarm window is deleted as shown in FIG. 10 (c). Perform the processing to be performed. The live-action image is actual photographic data obtained by capturing the position of the target object.

These targets include dozing driving accident points, radar, H system, LH system, speed limit switching point, control area, inspection area, ban monitoring area, N system, traffic monitoring system, intersection monitoring point, signal neglect suppression system. , Police station, accident-prone area, on-board aiming area, sudden / continuous curve (expressway), branch / confluence point (expressway), ETC lane advance guidance (expressway), service area (expressway), parking area (Expressway), Highway Oasis (Expressway), Smart Interchange (Expressway), Gas Station in PA / SA (Expressway), Tunnel (Expressway), Highway Radio Reception Area (Expressway), Prefectural Border Notification, Road There are stations, viewpoint parking, etc., and the type information of these targets, the latitude and longitude information indicating their positions, the schematic diagram or photograph data displayed on the display unit 5, and the audio data are stored in the database 19 in association with each other. The approach warning is given with reference to these.

In the radar wave warning function, a signal corresponding to a microwave (radar wave) in a frequency band emitted from a speed measuring device (mobile radar or the like (hereinafter, simply referred to as “radar”)) is detected by the microwave receiver 4. This is an alarm function that displays an alarm screen on the display unit 5 and outputs an alarm sound from the speaker 20. For example, when a microwave in the microwave frequency band emitted by the radar is detected by the microwave receiver 4, the voice data stored in the database 19 is read out and the voice "Radar. Speed caution" is emitted from the speaker 20. Output. During the audio output, the alarm lamp 6 is turned on. When a screen other than the map screen is currently 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 the audio output, FIGS. 11 (a) (b) (c) and 12 (a) (b) (c) are shown in this order. An animation drawing is performed by overlaying an alarm window for drawing an image based on a schematic diagram of a radar wave warning or photographic data on the map displayed on the map display section of the map screen (front). That is, FIG. 11A shows a state in which the radar wave is not received by the microwave receiver 4, and the map is displayed on the map display section of the map screen but the alarm window is not displayed. .. When a radar wave is received by the microwave receiver 4, as shown in the order of FIGS. 11 (b) and 11 (c), the right end of the alarm window gradually becomes the map display unit from the upper left to the lower right of the map display unit. The brightness of the display is brightened while increasing the size of the alarm window to a position slightly to the right of the center in the left-right direction of. As an animation, the object showing the shape of the target displayed inside the alarm window is rotated, and the characters stored in the database 19 such as "WARNING" are displayed in order from the leftmost character to the right in front of the object. I do. After performing this display for a certain period of time (for example, 10 seconds), as shown in the order of FIGS. 12A, 12B, and 12C, the process of gradually changing the animation into an image photographic image of this speed measuring device is performed. When the radar wave is no longer received, the alarm window displaying the image photograph image is faded out as shown in FIGS. 13A, 13B, and 13C.

The wireless alarm function is a function of issuing an alarm when the wireless receiver 15 receives a radio wave emitted by an emergency vehicle or the like so as not to interfere with the traveling or the like. In the radio alarm function, control radio, car location radio, digital radio, extra small radio, station activity radio, police telephone, police activity radio, wrecker radio, heli-tele radio, fire heli-tele radio, fire-fighting radio, emergency radio, highway radio , The frequency of the security radio, etc. is scanned, and when the radio is received at the scanned frequency, a schematic diagram indicating that the radio corresponding to that frequency stored in the database 19 for each radio type is received is used as an alarm screen. Along with displaying on the display unit 5, the voice data stored in the database 19 for each radio type is read out, and an alarm voice indicating the radio type is output from the speaker 20. For example, when a crackdown radio is received, a voice is output like "It is a crackdown radio. Be careful of speed." During the audio output, the alarm lamp 6 is turned on. When a screen other than the map screen is currently 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, for example, in FIGS. 14 (a), (b), and (c), a display indicating that it is a wireless alarm is displayed so as to show a part of the change. Except for this, the same processing as the radar wave warning function is performed.

On the auto item setting screen 2/2 of FIG. 16B, there is a "preset A" button for setting whether or not the preset A screen is to be switched and displayed in the first row and first column, and the first row and second column. "Preset B" button for setting whether to switch the preset A screen to the eyes, and to set whether to switch the preset C screen to the 1st row and 3rd column. "Preset C" button, "Positioning information" button for setting whether or not the positioning information screen is to be switched and displayed in the 1st row and 4th column, and the fuel consumption screen to be switched and displayed in the 2nd row and 1st column It is provided with an "fuel consumption" button for setting whether or not to perform the operation, and an "OBD data" button for setting whether or not the OBD data screen is to be switched and displayed in the second row and second column. The button name is displayed on the surface of each of these buttons. The button name of each button indicates the characters enclosed in brackets in the above sentence. For example, in the case of the "clock" button, the "clock" in the brackets is displayed as the button name. Each button is a rectangular button of the same size with the long side in the left-right direction surrounding these characters. A space of a predetermined width is provided between each button to prevent erroneous touch.

At the left end of each button, an indicator is provided between the upper end and the lower end of the button to show the image of a band-shaped LED lamp that lights in green with a width thinner than the button width. This indicator has a lit state and a non-lit 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 inverted. That is, if it is in a lit state, it is in a non-lit state, and if it is in a non-light state, it is in a lit state. When the indicator is lit, the screen corresponding to the button is the target of the switching display, and when the indicator is not lit, the screen corresponding to the button is stored in the database 19 as a setting not to be the target of the switching display. .. This storage process is performed when there is a change in the lighting state of the indicator.
When the press of the "EXIT" button is detected and the display of the AUTO screen is selected as shown in FIG. 3 (b) above, the processing of the AUTO display screen is started, and the database is targeted for switching display. Only the screen stored in 19 is switched every minute. Hereinafter, it is assumed that the display of the AUTO screen is selected as shown in FIG. 3 (b).

16 (a) and 16 (b) show an example in which the indicators are lit for all the buttons. This state is the default state described above. If a touch to the "EXIT" button is detected in this state, all screens are subject to switching display. That is, clock screen, speed screen, eco-drive 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, OBD data screen, respectively. The format screen is switched and displayed every 1 minute (each screen is displayed for 1 minute and switched to the next format screen. The same applies hereinafter). After displaying the OBD data screen for 1 minute, the screen returns to the clock screen, and the switching display is performed in the same manner thereafter.

FIG. 17A is an example in which the indicator of the “clock” button on the auto item setting screen 1/2 is in the non-lit state and the indicators of the other buttons are in the lit state. On the auto item setting screen 2/2, it is assumed that the indicators of all the buttons are lit as shown in FIG. 16B. When a touch to the "EXIT" button is detected in this state, all screens except the clock screen are subject to switching display. That is, the speed screen, eco-drive 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 in this order. Is switched and displayed every minute. After displaying the OBD data screen for 1 minute, the screen returns to the speed screen, and the switching display is performed in the same manner thereafter. Since the clock is displayed in the upper right of the screen of each format, users who think that it is not necessary to target the switching display can set it by touching each button so that it will be in such an indicator state. , It is possible to prevent the clock screen from being switched and displayed.

FIG. 17B shows an example in which the indicators of the “clock” button and the “tide information” button are not lit, and the indicators of the other buttons are lit. On the auto item setting screen 2/2, it is assumed that the indicators of all the buttons are lit as shown in FIG. 16B. When a touch to the "EXIT" button is detected in this state, all screens except the clock screen and the tide information screen are subject to switching display. That is, the screens of each format are displayed every minute in the order of speed screen, eco-drive 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. Switch to display. After displaying the OBD data screen for 1 minute, the screen returns to the speed screen, and the switching display is performed in the same manner thereafter. The clock screen and the tide information screen mainly depend only on the date and time, and do not change in real time as the vehicle travels. Therefore, a user who wants to know the real-time current state that changes as the vehicle travels can set the clock screen and tide information screen by touching and setting each button so that the indicator state is as such. Can be switched and displayed, and only the screen in the format that displays the current state in real time, which changes as the vehicle travels, can be switched and displayed.

FIG. 17C is an example in which the indicators of all seven buttons on the auto item setting screen 1/2 are not lit. On the auto item setting screen 2/2, as shown in FIG. 18A, the indicators of the "preset A" button, the "preset B" button, and the "preset C" button are lit, and the "positioning information" button, It is assumed that the indicators of the "fuel consumption" button and the "OBD data" button are not lit. When a touch to the "EXIT" button is detected in this state, the screens of each format are switched and displayed in the order of the preset A screen, the preset B screen, and the preset C screen every minute. After displaying the preset C screen for 1 minute, the screen returns to the preset A screen, and the switching display is performed 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 the screens of other formats from being displayed. By reducing the number of screens to be selected in this way, it is possible to shorten the time required for one repeated display (in this example, the time required for one repeated display is 3 minutes). Further, for example, when all the meters on these three preset screens are set to different types of meters, a total of nine types of meters can be confirmed in three minutes.

Next, the setting process of each meter displayed on the preset A screen, the preset B screen, and the preset C screen will be described. This setting process is started by a screen transition by detecting the following operation. As described above, first, when it is detected that the setting button of the remote controller 17 or the switch unit 3 is pressed in any of the screen display states, the setting screen of FIG. 15 is displayed. In this state, when a touch to the "standby" button at the upper left end is detected, the standby screen setting screen shown in FIG. 15B is displayed. When a touch to any of the "Preset A" button, "Preset B" button, and "Preset C" button in the second row is detected on this screen, the preset meter setting screen for that preset is displayed. Here, an example when the "Preset A" button is touched will be described. The same process is performed when the "Preset B" button or the "Preset C" button is touched.

When the "Preset A" button is touched, the preset meter setting screen as shown in FIG. 19A is displayed. Similar to the auto item setting screen, the preset meter setting screen has a screen title display section called "Preset A" at the top, and a control button display section with "EXIT" button and "BACK" button in order from left to right at the bottom. , A meter setting button display unit having three meter setting buttons arranged at positions corresponding to the left position meter, the middle position meter, and the right position meter in FIG. 7A between the screen title unit and the control button display unit. To be equipped. That is, the meter setting button display unit is a left position meter setting button for setting the type of the left position meter placed at the lower left position, and a middle position meter setting button for setting the type of the middle position meter placed at the upper center position. , Equipped with a right position meter setting button for setting the type of right position meter placed in the lower right position. On each button, a character string indicating the type of meter currently set is displayed. In the default state, as shown in FIG. 19A, the left position meter is set as the clock, the middle position meter is set as the vehicle speed, and the right position meter is set as the eco-drive for the preset A screen. The example in which the preset A screen is displayed in this state is the display example of FIG. 7A. That is, according to the setting of each meter setting button, the left position meter is displayed as a clock, the middle position meter is displayed as a vehicle speed, and the right position meter is displayed as an eco-drive.

The default settings for the preset B screen are as shown in FIG. 7B as a display example in which the left position meter is the clock, the middle position meter is the acceleration, and the right position meter is the vehicle speed. The default settings for the preset C screen are as shown in FIG. 7 (c) with the left position meter as the compass, the middle position meter as the tilt, and the right position meter as the tide information.

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

When a touch to the middle position meter setting button is detected, the meter type selection screen shown in FIG. 20A is displayed. The meter type selection screen includes a control button display unit having a back button, a blank, an up arrow button, and a down arrow button in the vertical direction on the right side, and four meter type buttons in the vertical direction on the left side thereof. As shown in FIG. 20A, the meter type currently set second from the top is first displayed. Since the setting of the middle position meter setting button in FIG. 19 (a) is "vehicle speed", "vehicle speed" is displayed on the second meter type button from the top, and this meter type button is highlighted to display the current meter type button. Indicates that it is in the selected state.

If a touch to the down arrow button is detected in this state, the display is shown in FIG. 19B. That is, the meter type button displayed second from the top is moved to the top, the meter type button displayed third from the top is moved to the second from the top, and the fourth from the top (first). The meter type button displayed in (bottom) is moved to the third from the top, and the meter type button newly set in the following order is displayed in the fourth (bottom) from the top. As a result, in this example, as shown in FIG. 20B, the vehicle speed meter type button is moved to the top. FIG. 20C shows an example of display when the touch of the down arrow button is detected three more times in this state. FIG. 21 (a) shows a display example in which the touch of the down arrow button is detected three more times from the state of FIG. 20 (c). FIG. 21 (b) is a display example in which the touch of the down arrow button is detected three more times from the state of FIG. 21 (a). FIG. 21 (c) shows a display example in which the touch of the down arrow button is detected three more times from the state of FIG. 21 (b). FIG. 22 (a) shows a display example in which the touch of the down arrow button is detected three more times from the state of FIG. 21 (c). FIG. 22 (b) shows a display example in which the touch of the down arrow button is detected three more times from the state of FIG. 22 (a). FIG. 22 (c) shows a display example in which the touch of the down arrow button is detected several more times from the state of FIG. 22 (b). The display state of FIG. 22 (c) is the same as the display state of FIG. 20 (a). In this way, by scrolling the meter type button cyclically, a settable meter type option is presented.

As shown in FIGS. 20 (a) and 20 (b), when a touch to the position of the acceleration meter type button is detected as the meter type button, the acceleration meter type is the button to which the highlight display is touched. While moving to the button, the setting of the type of the middle position meter of the preset A of the database 19 is changed to "acceleration" and stored. When a touch to the back button is detected in this state, the display on the middle position meter setting button is changed to this "acceleration" as shown in FIG. 19B. With this setting, when the screen of preset A is displayed, as shown in FIG. 23, the middle position meter becomes the meter of "acceleration" as shown in FIG. 23.
In this way, the user can set what kind of meter the meter at each position should be on each preset screen.

In this way, in the case of the AUTO display setting, when the preset screen is selected as the target of the switching display, the preset screen thus set by the user can be the target of the switching display.

The radar detector, which is an example of the control system according to the present invention as described above, displays screens of different formats displaying information on the current situation at predetermined time intervals such as 1 minute intervals in the predetermined order as described above. It is a control system that controls switching and display. The configuration is provided with a selection function for allowing the user to select a screen of the format to be the target of the switching display, and the screen area of the format selected by the selection function is the target of the switching display. Therefore, it is possible to display a screen in a format required by the user. As the information on the current situation, for example, information on the current time, the current date, the current position, the current situation regarding the vehicle where the display unit displayed by the control system is installed, and the like are displayed. In addition to or in place of these, a screen in a format that acquires and displays the current status of a person who visually recognizes the display of the system, for example, the driver himself / herself, may be provided. The current situation may be, for example, the situation at this moment, but in the present embodiment, for example, the position information is output from the GPS receiver 8 every second, so that the maximum is about 1 second. The range shows the situation before now. Since the vehicle information acquired via the OBD2 connector is also acquired at 0.5 second intervals, the previous situation is displayed within a range of up to about 1 second. The information about the current situation may be a past situation close to the present to the extent that the user recognizes the current situation, depending on the type and nature of the information to be displayed.

In the present embodiment, the predetermined order is the order displayed on the setting screen or the like as described above, but for example, the order may be set by the user instead of the predetermined fixed order. It may be in a random order.

In the present embodiment, the predetermined time interval is a predetermined fixed time interval such as a 1-minute interval, but the time interval may be changed according to the situation of the acquired information. Further, the predetermined time interval may be a time interval set by the user on the setting screen or the like. Also, for example, the time from displaying the screen of the first format to switching to the display of the screen of the second format, and the display of the screen of the third format after displaying the screen of the second format. The time until switching may be the same time or different times.

The switching display of the present embodiment is configured to rewrite the current screen area to the next screen area in the time between the hoolems. That is, the current screen and the next screen are displayed so as to switch between them. However, at the time of rewriting, for example, a predetermined switching effect is displayed such that the screen area is gradually scrolled out and another screen area is scrolled in, or the screen area is faded in and faded out in the same manner. You may do so.

In the present embodiment, as information on the current situation, preset A, preset B, preset C, etc., which include a plurality of different information acquired about the moving body and simultaneously display a plurality of different information as screens of different formats, are used. It is configured to have multiple screens in the format of triple meters. Therefore, a plurality of different information acquired about the moving body fluctuates with the movement of the moving body, and the fluctuation can be grasped at the same time by looking at a screen in the format of a triple meter that simultaneously displays a plurality of different information. Further, a plurality of screens in the format of a triple meter for displaying a plurality of different information at the same time are provided, and the display function of the AUTO screen controls switching and display at predetermined time intervals in a predetermined order. , It is possible to grasp a large amount of information that fluctuates with the movement of a moving body in a short time.

Although the moving body is a vehicle in the present embodiment, it may be a person, for example. If it is a person, it is preferable to sense and acquire a physiological phenomenon such as a person's heartbeat and body temperature, or to sense and acquire the person's position and surrounding conditions.

On the auto item setting screen, as shown in FIGS. 16A and 16B, the indicators of all the buttons are set to be lit. In this way, the selection function is configured so that in the default state, screens of all selectable formats are targeted for switching display, and screens of formats that are not targeted for switching display are selected by selection by the user's touch. Therefore, in the default state, the screens of all selectable formats are switched and displayed in a predetermined order at a predetermined time interval. This allows the user to know the screens in all formats that can be selected by the radar detector. Then, for example, after using it for a while in this state, as described above, by selecting a screen in a format that is not necessary for oneself as a screen in a format that is not the target of switching display, only a screen in a format that is necessary for oneself is selected. It can be switched and displayed.

On the auto item setting screen, as shown in FIG. 16 and the like, characters representing the screen of each format are displayed on the buttons and selected. Therefore, it is preferable to display the characters displayed on this button when switching the display. For example, when switching to the speed screen as shown in FIG. 5A, as shown in FIG. 24, a horizontal band-shaped telop area is displayed above the speed screen, and the characters on the button are displayed in the telop area. "Speed" is displayed. This display is displayed for 3 seconds from the time of switching and then erased. In this way, it is easy to determine which screen should be selected when the selection function is executed by looking at the display of information representing the screen of each format (in this example, the telop displayed for a certain period of time when switching screens). At the same time, when the screen is switched and displayed, it is possible to confirm that the information representing the format screen is properly set. The information representing the screens of each format may be, for example, a character string of a name attached to each screen, a thumbnail screen in which each screen is reduced in size, an illustration or an icon indicating the contents of each screen, or the like. The information representing the screen of this format is displayed in the screen of the format in the case of switching, and is erased when a predetermined time has elapsed after switching. The predetermined time until the erasing is 3 seconds. It is configured to be shorter than 1 minute, which is a predetermined time from displaying the screen of the relevant format to switching to the screen of another format. In this way, the information representing the screen of the format is deleted in the screen of the format for a predetermined time. After that, the screen of the format is displayed in a state where the information representing the screen of the format is not displayed, and then the screen is switched to the screen of another format. Therefore, when the screen is switched, what kind of information is displayed on the screen of the format can be grasped by the information representing the screen of the format, and the screen of the format is represented in the state where the grasp can be obtained. The information to be displayed can be erased, and the entire screen can be displayed in a predetermined format.

Further, as at least one of the format screens that can be selected on the auto item setting screen, it is preferable to provide a format screen that controls switching and displaying a predetermined display area in the format screen at predetermined time intervals. Then, the predetermined time interval of the switching display from the screen of the format to the screen of another format is longer than the predetermined time interval of the switching display of the predetermined display area in the screen of the format (until now in the present embodiment). As explained in 1), the configuration should be 1 minute). For example, when the tide information meter shown on the right position meter of the preset screen of FIG. 25 is used as the predetermined display area and the screen is switched to this preset screen, the tide is measured closest to the current position as shown in FIG. 25 (a). A tide information meter that displays the place name, the age of the current date, and the tide name is displayed. Then, after 10 seconds have passed, a tide information meter that displays the time and tide level of the first low tide of the day and the time and tide level of high tide as shown in FIG. 25B is displayed. Then, when 10 seconds have passed since the tide information meter shown in FIG. 25 (b) was displayed, the tide that displays the time and tide level of the second low tide of the day and the time and tide level of high tide as shown in FIG. 25 (c). Display the information meter. Then, when 10 seconds have passed after displaying the tide information meter shown in FIG. 25 (c), the display returns to the display of the tide information meter shown in FIG. 25 (a). Then, once again, the tide information meter on the screen of FIG. 25 (a) is displayed for 10 seconds, the tide information meter on the screen of FIG. 25 (b) is switched to, and the tide information meter on the screen of FIG. 25 (b) is displayed. Display for 10 seconds and switch to the tide information meter on the screen shown in FIG. 25 (c). Then, when the tide information meter on the screen of FIG. 25C is displayed for 10 seconds, one minute has passed since the screen was switched to this preset screen, so that the screen is switched to the screen of the next format. In this way, the format is displayed at a time interval (10 seconds in the present embodiment) shorter than the time interval (1 minute in the present embodiment) for switching to the screen of another format after the screen of the format is displayed. The contents of the tide information meter, which is a predetermined display area in the screen of, are switched and displayed. Therefore, the screen will not be switched to another format without switching the predetermined display area (tide information meter in this example) in the screen of this format at all. Therefore, it is possible to visually recognize a large amount of information in a short time by switching the display of a predetermined display area in the screen of the format and switching the screen itself of the format. In addition, this information can be confirmed without waiting for the lap of the switching display announcement. For example, when the tide information screen of the day shown in FIG. 25 is displayed, the screen shown in FIG. 26 is displayed, but this content is confirmed by the switching display of the content of the tide information meter in a narrower area. You can check all the contents within the display time (1 minute) of the preset display screen without waiting until the next preset screen is displayed. If there is no time for the second low tide or high tide, it may be left blank or the meter display may be skipped.

In the present embodiment, a graph screen as illustrated in FIG. 6C is provided as at least one screen having a format that can be selected on the auto item setting screen. Like this graph screen, it is equipped with a screen in a format that makes it possible to grasp the current situation by comparing the current situation with the past situation, and a predetermined time for switching from that format screen to another format screen. The interval may be configured as a time interval in which the current situation can be grasped by comparing the current situation with the past situation. The graph screen has a display time of 1 minute, and the current situation can be grasped by comparing the current situation with the past situation. By doing so, it is possible to visually compare the current situation and the past situation before the screen of the currently displayed format is switched to the screen of another format.

In the present embodiment, when a screen other than the map screen is currently displayed as the information display function, and when an alarm is given by the GPS alarm function, the radar wave alarm function, or the wireless alarm function, a process of outputting a voice is performed. However, while the alarm sound is being output, the user may switch to the map screen and perform an alarm using an alarm window or the like similar to the alarm when the map screen is displayed. In this case, the format screen that can be selected on the auto item setting screen should not include the map screen. When a predetermined event (alarm in the present embodiment) occurs during execution of the function of switching and displaying screens of different formats in a predetermined order at a predetermined time interval, the screen is switched to a screen for notifying the occurrence of the event. It is preferable that the event screen display switching function to be displayed is provided, and the screen having the same format as the screen notifying the occurrence of the event is not provided as the screen of the format that can be selected as the target of the switching display. By doing so, the screen having the same format as the screen notifying the event occurrence is not switched and displayed in a predetermined order at a predetermined time interval by the display function of the AUTO screen, so that the user can display the event occurrence. It can be surely known, and the screens that are switched and displayed in a predetermined order at a predetermined time interval are not mistakenly recognized as an event occurrence screen.

In the present embodiment, the example in which the display unit 5 is provided with the touch panel has been described, but the configuration may include only the remote controller 17 or the switch unit 3. For example, the selection target is indicated by moving the focus frame in response to the detection of the button operation, and when the press of the enter button is detected, the item with the focus frame is stored in the database 19 as the selected item. The screen switching process may be performed with reference to the stored items. For example, on the standby screen setting screen shown in FIG. 15B, the focus frame is moved in response to the detection of pressing the up / down / left / right buttons of the remote controller, and the remote controller 17 is in a state where the focus frame is in the "auto item" at the upper right end. When the press of the enter button is detected, the auto item setting screen 1/2 shown in FIG. 16A is displayed. When the press of the lower button is detected while the focus frame is on any of the buttons in the second row, or when the focus frame is on the "graph" button in the second row and third column, the right button When the press is detected, the auto item setting screen 2/2 shown in FIG. 16B is displayed. The auto item setting screen 2/2 also displays a total of seven toggle buttons having four buttons on the first line and three buttons on the second line. When the press of the upper button is detected while the focus frame is on any button in the first row of the auto item setting screen 2/2, or when the focus is on the "Preset A" button in the first row and first column. When the right button is detected while there is a frame, the auto item setting screen 2/2 shown in FIG. 16A is displayed. When the press of the enter button is detected, an item with a focus frame is stored in the database 19 as a selected item, and the screen switching process or the like is performed with reference to this stored item.
