Description

The present invention relates to a system that supports the driving of a vehicle by providing information on various traffic monitoring activities such as traffic control and inspection.

Conventionally, as a system for supporting the driving of a vehicle, an in-vehicle device such as a radar detector that warns when a radar wave of speed control is received and calls the driver's attention has been realized. Such an in-vehicle device has a GPS function for positioning the current position of the vehicle and a database of GPS targets such as the installation point of the speed control system, and detects the approach to a specific GPS target. Some notify the driver (see, for example, Patent Document 1). With such an in-vehicle device, it is possible to prevent the driver from unknowingly overspeeding by notifying the approaching point of the traffic monitoring activity.

As GPS targets that the in-vehicle device with the above configuration notifies the approach, in addition to the installation point of the speed control system and the permanent point such as the police station, traffic monitoring activities such as speed control by mobile orbis and drinking inspection are frequently performed. There are temporary points, etc. that will be implemented at. The in-vehicle device is trying to raise the driver's awareness of safe driving by notifying the approach to various GPS targets.

In particular, vehicle speed measuring devices and the like applied to speed control are often installed at dangerous points where excessive speed is likely to be induced. The approach notification to such a point is very effective for raising the driver's awareness of safe driving before the danger occurs and for avoiding the danger. In-vehicle devices such as radar detectors are extremely useful for motivating drivers to drive safely, and are devices that contribute to ensuring traffic safety and support driving.

However, the above-mentioned conventional in-vehicle device has the following problems. In other words, while there are users who request the presentation of a lot of information such as the type of traffic monitoring activity to be alerted, the execution position, and the distance to the implementation point, the amount of information presented is too large to understand the alarm. There are not a few users.

The present invention has been made in view of the above-mentioned conventional problems, and is an invention for providing a system capable of transmitting monitoring information on traffic monitoring activities in an easy-to-understand manner.

The first aspect of the present invention is a system for notifying monitoring information regarding traffic monitoring activity.
With multiple indicators with screens
The system includes a control means for acquiring monitoring information related to traffic monitoring activity and executing control for displaying the monitoring information on the screen of at least one of the indicators.

A second aspect of the present invention is a program for causing a computer to realize the function of the first aspect as a system.

The system according to the present invention includes a plurality of indicators for displaying monitoring information related to traffic monitoring activities. If the monitoring information is displayed using a plurality of indicators, the amount of display information per indicator can be reduced, and easy-to-understand monitoring information can be notified.

The number of indicators included in the system according to the present invention may be two or three or more.
The system according to the present invention may be used, for example, for in-vehicle use or for purposes other than in-vehicle use.
The control means provided in the system of one preferred aspect of the present invention displays the monitoring position information indicating the execution point of the traffic monitoring activity on one of the indicators, and displays the type of the traffic monitoring activity on the other indicator. It is possible to execute control to display the monitoring type information to be represented.
In this case, by separating the display for displaying the monitoring position information and the display for displaying the monitoring type information, each information can be displayed in an easy-to-understand manner. For example, in the case of plotting the implementation points on a scope surface that imitates a map or radar scope, the size of the map or scope surface is very important in order to grasp the monitoring position information. Since it is not necessary to display the monitoring type information on the map or scope surface or to narrow the map or scope surface to secure a place to display the monitoring type information, the monitoring position information can be displayed in an easy-to-understand manner.

The control means provided in the system of one preferred aspect of the present invention displays a scope surface representing a predetermined area around the vehicle on any one of the indicators, and displays an icon indicating an execution point of a traffic monitoring activity on the scope. Plot on the surface
It is possible to execute control to display character information indicating the type of traffic monitoring activity related to the icon plotted on the scope surface on any of the other indicators.
In this case, the positional relationship between the own vehicle and the implementation point can be displayed in an easy-to-understand manner by using any one of the indicators. Further, if the character information is displayed on any of the other indicators, the type of traffic monitoring activity can be displayed in a very easy-to-see manner.

A plurality of indicators included in the system of one preferred aspect of the present invention can display a predetermined standby screen when the monitoring information is not notified, and each indicator has its own standby screen. Can be selectively set.
If the standby screen can be set for each display, the number of combinations of standby screens to be displayed will be very large. For example, if 10 types of standby screens can be set for each of the two indicators, 10 × 10 = 100 combinations are possible. If there are a plurality of displays, a plurality of types of standby screens can be displayed in parallel, and the types of information that can be presented increase. For example, by setting a standby screen for displaying the time and a standby screen for displaying the vehicle speed, it is possible to realize a standby state in which the time and the vehicle speed can be grasped at a glance.

In the system of one preferred aspect of the present invention, as a setting mode for selectively setting the types of display screens to be displayed on the plurality of indicators, at least two types of setting modes having different numbers of selectable display screen types can be selected. Is provided, and an operation means for selecting one of the setting modes is provided.

In a system provided with a plurality of indicators, the degree of freedom of setting on the user side is extremely high. If you are a user who enjoys using such a system, you can make advanced settings. On the other hand, for users who place importance on basic functions rather than mastering the system, it may be difficult to master due to the high degree of freedom of setting. Therefore, by providing multiple types of setting modes with different degrees of freedom as described above, the degree of freedom of setting can be selected according to the user's preference, and a wide range of user needs from heavy users to general users. Can be supported.

The setting mode in the system of one preferred aspect in the present invention includes the setting mode in which the type of the display screen to be displayed on the plurality of indicators can be selectively set, and the display screen to be displayed on the plurality of indicators. It includes a simple setting mode in which the type is specified in advance and the type of display screen cannot be changed.
If the easy setting mode is prepared, the basic functions can be used immediately after purchase, and a user-friendly system that can be introduced relatively easily can be realized. After that, when there is a need to use it more deeply through use, you can select the setting mode that allows detailed settings.

In a system of one preferred embodiment of the present invention, a gap is provided between at least one of the plurality of indicators arranged adjacent to each other, and a detection sensor that detects a human body in close proximity is said to be provided. It is arranged in the gap.
The detection sensors arranged between the adjacent displays are suitable for detecting, for example, a hand-holding operation on the screen. When only one display is provided, it is very difficult to arrange the detection sensor at an intermediate position on the screen, and it is difficult to realize an operation feeling like holding a hand over the screen. Even if there are a plurality of indicators, adjacent screens can be easily visually recognized as if they were one screen. If the detection sensor is arranged in the gap, it is possible to realize an operation feeling as if the user holds his / her hand over the screen.

A preferred embodiment of the system of the present invention comprises an operating unit having lighting means for lighting the operating area.
The control means can execute control to switch the operation area to the lighting state according to the detection of the human body by the detection sensor.
In this case, it is possible to realize a novel operation feeling such that the system is started by a hand-held operation or the like. You can realize the joy of operation like operating with hand power.

A preferred embodiment of the system of the present invention comprises an operating unit having lighting means for lighting the operating area.
The control means can execute blinking control for alternately switching between a lighting state and an extinguishing state or a dimming state for the operation area.
By executing the blinking control, it becomes possible to make a specific operation area stand out. Further, for example, the blinking control cycle may be changed. For example, it is also possible to express information that the situation is urgent by increasing the cycle. For example, it is also possible to realize control in which light moves between a plurality of operation areas by executing blinking control for a plurality of operation areas and changing the phase of the blinking control. In this case, a two-dimensional movement of light moving can be generated, and visual enjoyment can be produced.

The control means provided in the system of one preferred aspect of the present invention acquires the notification necessity degree for the monitoring information, and changes the cycle of blinking the operation area according to the notification necessity degree.
For example, if the cycle is increased as the degree of necessity of notification increases, it is possible to intuitively convey that the situation is urgent, and it is possible to present information that is easy to understand at first glance.

In the system of one preferred aspect of the present invention, operation units having lighting means for lighting the operation area are provided on the left and right sides of the area where the screens of the plurality of indicators are arranged.
The control means can execute control to notify the direction of the execution point of the traffic monitoring activity depending on which side of the operation units arranged on the left and right sides is turned on.

In this case, the operation unit can be used to notify the direction of the implementation point. The azimuth notification by lighting the operation unit is an extremely simple notification method, and can be a notification that the user can intuitively grasp at a glance. Further, if the operation unit can be used to notify the direction of the implementation point, for example, it is not necessary to display the direction on the display side. The amount of information displayed on the display can be reduced, and the display on the display can be configured in an easy-to-understand manner.

In one preferred aspect of the system of the present invention, at least one of the plurality of indicators has a screen normal angle that is different from that of the other indicators.
When there is only one display, it is difficult to set a plurality of screen orientations (normal directions) even if the size of the screen can be enlarged by changing the display. When a plurality of indicators are provided as in the system according to the present invention, it is relatively easy to realize a configuration in which the orientation of the screen is different. For example, it is also possible to provide indicators on a plurality of surfaces of the dice-shaped housing and to display different information on each indicator. In this case, the display information that can be visually recognized from the user side can be switched by changing the orientation of the dice-shaped housing.

In a preferred one-mode system of the present invention, at least one of the plurality of indicators has a screen that is substantially parallel to the screens of the other indicators, but is not flush with each other and has a different position in the depth direction. ing.
In this case, the display can be given a sense of depth. While the information that can be displayed on the screen is two-dimensional information in a plane, it is possible to give a sense of depth to the displayed information by using a plurality of indicators having different positions in the depth direction. For example, it is possible to control such that important information is displayed on the display on the front side and less important information is displayed on the display on the back side. In this case, the user can intuitively recognize important information.

■ 1. Shape ■
As shown in FIGS. 1 to 12, the radar detector 1 of this example includes a horizontally long and wide case body (housing) 2 and is installed on a vehicle dashboard or the like via a bracket 28 (FIGS. 9 to 12). Radar. The radar detector 1 can be installed on the back side of the sun visor, the back side of the rearview mirror, and the like according to the change of the bracket 28. The radar detector 1 can also be used by removing the bracket 28. When the bracket 28 is removed, it can be installed directly on the dashboard or the like by using the adhesive force of the double-sided tape or the like attached to the bottom surface of the case body 2.

On the front surface (front surface) of the radar detector 1, a screen area 15A (FIG. 1) in which two 1.8-inch color screens 15L and two Rs are arranged side by side in the left-right direction (horizontal direction) is formed. Above and below the boundary between the left and right screens 15L and R, a label area 210 on which the model number and model name of the radar detector 1 are printed is provided so as to bite into the screen area 15A. Operation buttons (operation means) 24 forming an operation area (predetermined area) are arranged on both sides of the screen area 15A as a display area. On the right outside of the screen 15R on the right side when viewed from the driver side, ▲ button 242, ▼ button 244, and MUTE (silence) button 248, which are volume adjustment buttons, are arranged. A MEMO button 241 and a VIEW button 243 are arranged on the left outer side of the screen 15L on the left side.

A card insertion slot 251 for inserting a memory card 171 (FIG. 28) such as an SD card, which is a removable recording medium, is provided on the right side surface of the case body 2 when viewed from the driver side. A USB connector 252, a power switch 253, a bracket 28 mounting portion 258, and the like are provided on the lower portion of the back surface of the case body 2. A cigar plug cord extending from a cigar socket of a vehicle, an OBD adapter (FIG. 13), a USB cable, and the like are connected to the USB connector 252. The radar detector 1 operates by receiving power supply via a cord connected to the USB connector 252.

The OBD adapter shown in FIG. 13 is provided on the vehicle side in accordance with the vehicle inspection standard OBD (On-board Diagnostics) -II (II is the Roman numeral "2", hereinafter referred to as "OBD"). It is a communication cable connected to the OBD connector. This OBD connector, which is also called a failure diagnosis connector, is electrically extended from a vehicle ECU (not shown) and can output various vehicle information. A connector that is detachably attached to the OBD connector of the vehicle is attached to the tip of the OBD adapter on the vehicle side.

■ 2. Structure ■
As shown in FIG. 14, the radar detector 1 is configured by attaching a touch screen sheet 151 to the front surface of the case body 2 that houses the first and second substrates 31 and 32. The case body 2 has a two-part structure in which a front frame 21 on the front side and a case 22 on the back side are combined.

The touch screen sheet 151 of FIGS. 14 and 15 is a horizontally long sheet that is arranged close to the entire width of the case body 2 in the left-right direction. A constricted shape 151D that protrudes downward or upward from the outer peripheral side to the inner peripheral side is provided in the middle portion of the touch screen sheet 151 (FIG. 15) in the left-right direction, and a narrow portion having a narrow vertical direction is formed. Has been done. The touch screen sheet 151 provided with the narrow portion has a shape like glasses as a whole.

In the touch screen sheet 151, touch areas (detection areas) 151S are formed in two vertical rows on the left side and the right side of the screens 15L and R, respectively. Instead of the configuration of this example, a touch area may be provided in the middle of the two rows of left and right touch areas 151S. By providing the screen 15 with three rows of touch areas in this way, for example, it becomes possible to detect a touch operation in which the touch position moves from the touch area on the right side to the left side via the center, so that a so-called flick operation can be performed. It will be possible.

At both ends of the touch screen sheet 151, characters such as MEMO and watermarks 151V such as triangles (▲ and ▼) are provided at positions corresponding to the respective operation buttons 24 (FIG. 1). According to the watermark 151V of the touch screen sheet 151, the operation area of the operation button 24 can be clearly indicated by transmitting the light of the white LED (illumination means) 137 housed inside.

The front frame 21 of FIGS. 16 and 17 has a shape similar to that of a frame provided with an opening 218. The opening 218 is an opening for arranging the two liquid crystal displays (displays) 152L and R mounted on the first substrate 31. Through holes 29 are formed at positions corresponding to each operation button 24 in the frame portion of the front frame 21. The through hole 29 on the left side when facing the front side lacks one side surface in the circumferential direction and is an incomplete hole communicating with the opening 218.

A shallow recessed portion 210A that matches the sheet shape of the touch panel 151 is formed on the outer surface corresponding to the front side. The bottom surface of the shallow recessed portion 210A is substantially flush with the surfaces of the liquid crystal displays 152L and R in the assembled state. The touch screen sheet 151 is attached to the recessed portion 210A along the surface of the liquid crystal display 152L, R.

Label regions 210 projecting from the outer peripheral side toward the opening 218 side are formed above and below the front surface of the front frame 21. The upper label area 210 is formed so as to project downward in the vertical direction, and the lower label area 210 is formed so as to project upward in the vertical direction. Each label area 210 is formed so as to be raised above the bottom surface of the recessed portion 210A by the thickness of the touch screen sheet 151. In the assembled state in which the touch screen sheet 151 is attached to the front frame 21, the combination of the label area 210 protruding from the vertical direction and the glossy touch screen sheet 151 forms a front appearance like glasses. ing.

The label area 210 of the front frame 21 matches the constricted shape 151D (FIG. 15) of the touch panel 151 described above, and has a positioning shape when the touch screen sheet 151 is attached. In the radar detector 1 of this example, since the positioning shape is located at the intermediate portion in the left-right direction of the case body 2, it is not necessary to start sticking the touch screen sheet 151 from either the left or right end side. For example, it is possible to start pasting from either the top or bottom.

If there is a deviation in the angle of the touch screen sheet 151 when trying to start pasting the touch screen sheet 151 from either the left or right end, the deviation is amplified toward the opposite end and the pasting ends. Very large deviation may occur. On the other hand, when the positioning shape is provided in the middle portion in the left-right direction, for example, it is possible to start sticking from the middle portion in the left-right direction of the touch screen sheet 151 and stick it on both sides in the left-right direction.

When the touch screen sheet 151 is started to be attached to both sides in the left-right direction from the middle portion, the distance from the start of the attachment to the end of the attachment is about half, so that the deviation generated at the left and right ends is small. Further, for example, it is possible to start sticking the touch screen sheet 151 in the vertical direction from either the upper or lower side. Since the width of the touch screen sheet 151 in the vertical direction is narrow, for example, even if there is a slight angle deviation when the touch screen sheet 151 is started to be attached from the upper side, there is little possibility that a large deviation will occur on the lower side.

On the back side of the front frame 21 (see FIG. 17), screw columns 213 are erected at four corners, and two screw holes 211 are bored at upper and lower positions. A seat portion that comes into contact with the first substrate 31 is formed on the outer periphery of the screw hole 211. A tubular portion is extended in the through hole 29 corresponding to each operation button 24, and the end surface thereof is flush with the seat portion of the screw hole 211 so as to be in contact with the first substrate 31. ing.

A seat portion 213A extending linearly in the radial direction is provided on the outer peripheral side of the screw column 213. The seat portion 213A is formed at a circumferential position corresponding to the outer peripheral side of the front frame 21 in the vertical direction and a circumferential position corresponding to the outer peripheral side of the front frame 21 in the left-right direction. For example, the lower right screw column 213 (see FIG. 17) when the front frame 21 is viewed from the back side is provided with a seat portion 213A extending downward and a seat portion 213A extending to the right side. The seat portion 213A is formed to be lower in height than the screw column 213, and the difference in height is substantially the same as the thickness of the second substrate 32 (slightly smaller than the thickness of the substrate 32).

The case 22 of FIG. 18 is a bottomed member screwed to the front frame 21. A switch hole 253H, a USB connector hole 252H, and the like are bored in the bottom surface of the case 22. At the four inner corners of the case 22, columns 221 with through holes are erected.

The end face of the support column 221 forms a seat portion that abuts on the second substrate 32. Further, each hole such as the speaker hole 254, the switch hole 253H, and the USB connector hole 252H is provided with a cylinder portion and a seat portion (hereinafter, referred to as a cylinder portion and the like). Further, a seat portion 226 is also provided on the inner upper part of the case 22. The support column 221, the tubular portion, and the seat portion 226 are formed at the same height so as to be substantially flush with each other. In the assembled state, the seat portion 226 such as the support column 221 and the tubular portion is in contact with the second substrate 32.

Two ribs 222 and 223 for supporting the first and second substrates 31 and 32 are provided on the upper, lower, left, and right inner peripheral side surfaces of the case 22. The ribs 222 and 223 are erected on the bottom surface in a state of being connected to the inner peripheral side surface of the case 22. As will be described in detail later, the ribs 222 on both the left and right sides are housed in slit holes 312 and 222 provided on the outer periphery of the substrates 31 and 32 (FIGS. 20 and 25). The upper and lower ribs 223 are housed in slit holes 313 and 323 provided on the outer circumferences of the substrates 31 and 32.

The left and right ribs 222 have a constant cross-sectional shape in the depth direction of the case 22. On the other hand, of the upper and lower ribs 223, the upper left, upper right, and lower left (FIG. 18) ribs 223 have the end faces on the opening side formed in steps in a stepped manner, and the inner peripheral side is higher than the bottom surface. Is low (see FIG. 19). The lower end surface forming the shelf surface is a contact surface with respect to the first substrate 31 in the assembled state. The rib 223Z located at the lower right (FIG. 18) has a constant cross-sectional shape in the depth direction of the case 22, and no shelf surface is formed.

In the following description, with respect to the rib 223 in which the end face on the opening side is formed in a stepped manner and the protruding width of the tip is narrowed, the portion on the root side is referred to as the rib body portion 223B, and the portion having the narrow protruding width at the tip is referred to. The rib tip is called 223A.

The first substrate 31 in FIG. 20 is a double-sided mounting substrate. Liquid crystal displays 152L and R are mounted on the mounting surface (see FIG. 20) on the front frame 21 side (front side) of the first substrate 31. A memory card reader 17 (see FIG. 24) is executed on the mounting surface facing the second substrate 32 on the back side thereof. Two notch portions 319 are provided on the lower side of the first substrate 31, and a connector 319C for connecting the control cables (flexible flat cables) of the liquid crystal displays 152L and R is provided in the notch portions 319, respectively. It is installed facing the.

On the surface of the substrate 31 on the side on which the liquid crystal displays 152L and R are mounted, the operation unit 315 including the capacitive touch sensor 315A and the white LED 315B (FIG. 28) is arranged at each position corresponding to the operation button 24. Has been done. In the assembled state, the tubular portion of the through hole 29 of the front frame 21 abuts on the first substrate 31 as described above, and the operating portion 315 is located inside the tubular portion (FIG. 21).

The white LED 315B is a lighting means that illuminates the operation area of the operation button 24 from the back side. The light of the white LED 315B passes through the watermark 151V (see FIG. 15) of the touch screen sheet 151 to clearly indicate the operation area. Each white LED 315B can be controlled to change the brightness of the illumination. It should be noted that a multi-color LED can be adopted instead of the white LED 315B. If a multi-color LED is adopted, it is possible to control not only changing the brightness but also changing the color.

In the gap 152S between the left and right liquid crystal displays 152L and R, for example, a proximity sensor (detection sensor, electronic component) 125 (not shown) for detecting a human body with equal hands is arranged. The proximity sensor 125 is used to detect a hand-holding operation on the screen area 15A (FIG. 1) in which the screens 15L and R are arranged.

The second method is to set << radar scope >> for the left screen 15L, and set << display switching distance → distance setting >> and << target information → telop >> for the right screen 15R. In the case of this method, when the distance between the own vehicle and the target reaches the distance set by the display switching distance, the warning screen as shown in FIG. 43 is switched and displayed. It should be noted that which of the left and right screens 15L and R to display the telop 41 can be selectively set by the operation on the user side.

(3) 1 screen warning 2
As shown in FIG. 44, the display pattern of the one-screen warning No. 2 is a display pattern in which the left screen 15L displays the standby screen and the notification panel screen is displayed on the right screen 15R at the time of an alarm. This 1-screen warning 2 can be displayed by setting the standby screen other than the radar scope screen to the left screen 15L, and setting << display switching distance → no switching >> and << target information → notification panel >> for the right screen 15R. .. It should be noted that which of the left and right screens 15L and R is used to display the notification panel screen can be set by the setting item of << notification display >>.

(4) No warning screen As shown in FIG. 45, the display pattern without a warning screen displays the standby screens on both the left and right screens 15L and R, and at the time of an alarm, either the left or right screen 15 (the right screen in the same figure). This is a display pattern in which only the telop 41 is displayed in the example of 15R). For the display pattern without warning screen, set the standby screen other than the radar scope screen for both the left and right screens 15L and R, and set << display switching distance → no switching >> and << target information → telop >> for the right screen 15R. Can be displayed. Whether to display the telop 41 on the left or right screen 15 can be set by << notification display >>.

■ 7. Alarm operation ■
(1) Alarm operation when receiving a crackdown radio wave When a crackdown radio wave such as a radar wave or a stealth wave is received, the control unit 10 executes an alarm operation such as displaying a warning screen on the screen 15 and outputting an alarm sound. .. FIG. 46 is an example of an alarm by the left screen 15L in which the radar scope screen is set as the standby screen. The control unit 10 executes a W alarm that gives an alarm by both a sound (electronic sound / alarm voice) and a screen display. The control unit 10 changes the scope surface of the radar scope screen to red, and displays a telop 41 indicating the type of traffic monitoring activity at the upper part of the radar scope screen. The telop 41 includes a display (for example, L5) of the reception level of radio waves such as radar waves.

When a predetermined mute operation is performed during the alarm, the control unit 10 executes a control to temporarily turn off the alarm sound until the radar wave being received is no longer received. The mute operation includes a hand-holding operation of holding a hand over the screen area 15A (FIG. 1) for a certain period of time (1 second), a long-pressing operation of the MUTE button 248, and the like. Further, when the reception of the radar wave continues for about 30 seconds or more, the control unit 10 automatically executes the control to reduce the volume of the alarm sound.
Further, as shown in FIG. 47, in the alarm operation at the time of receiving the crackdown radar wave, the control unit 10 electronically responds to a change (L1 → L5) in the reception level (radio wave intensity) due to the approach of the radar wave to the source. The control to raise the tempo of the sound is executed.

(2) Alarm operation when the target approaches The control unit 10 displays a telop 41 that displays the target information and the distance in characters as shown in FIG. 48 when the distance between the own vehicle and the target becomes small (when the target is approached). It is displayed at the top of the screen 15.

FIG. 3A is an example when << telop display >> is set for the clock screen set as the standby screen. FIG. 3B is an example when << telop display >> is set for the radar scope screen. In the case of the radar scope screen of the left screen 15L, the time is not displayed, but in the case of the radar scope screen of the right screen 15R, the time is displayed in the lower right. FIG. 3C shows a change in the background color of the screen 15 controlled by the control unit 10 according to the degree of caution of the alarm. Figure (d) is an example when << Telop display >> is set on the notification panel screen.

(3) Alarm voice When the control unit 10 outputs an alarm voice by voice to a target located at about 25 ° or more (see FIG. 49) in the right-hand or left-hand direction with respect to the traveling direction, the alarm voice is “leftward” or Add the phrase "right direction" and execute the control to announce the direction (direction of the implementation point). The "right" and "left" voices are the target directions at the time of notification. If the distance to the target is very short, the phrase for identifying the left-right direction may not be added. Here, "" means the voice output by the alarm voice.

The alarm voice is output at each timing shown in FIGS. 50 to 53. In FIG. 50, an alarm voice regarding orbis (speed violation control) is shown in the upper row, and an alarm voice regarding a control area is shown in the lower row.
For example, in the case of an Orbis alarm voice, stages of 2 km ahead (only on expressways), 1 km ahead, 500 m ahead, immediately before, and passing are set, and an alarm voice is output for each stage under the control of the control unit 10. At each stage up to 500 m ahead, a distance such as "2 km ahead" is output as voice. Further, at 1 km ahead, in addition to the voice output of the distance, an alarm voice or the like notifying the speed limit or overspeed is output, and at 500 m ahead, an alarm voice notifying the camera position is output. When the speed is exceeded immediately before, the control unit 10 executes control to output a warning voice of the speed excess notification in addition to the immediately preceding traveling speed notification.

For example, in the case of an alarm voice in a control area, each stage of 1 km ahead, area entry, and area exit is set, and an alarm voice is output for each stage under the control of the control unit 10. At the stage 1 km away, the alarm voice also outputs whether the area is in the left-right direction. While the display screen other than the radar scope screen is being displayed, the control unit 10 displays an icon (see FIG. 40) corresponding to the control / inspection area at the lower part of the display screen.

The voice output (utterance) of the alarm voice or the like can be muted (silenced) by holding the screen area 15A (FIG. 1) by hand. The control unit 10 outputs a voice when the proximity sensor 125 arranged in the gap 152S (FIG. 20) of the left and right liquid crystal displays 152L and R detects the human body and the duration of the detection state reaches 1 second. Control so that it is muted and not output. If a threshold value such as 1 second is set for the duration of the detection state, for example, there is little possibility of erroneously detecting the movement of the driver's hand trying to operate the audio or the like by releasing the hand from the steering wheel.

■ 8. Various settings ■
In the radar detector 1, a plurality of types of operation specifications are prepared, and the desired operation specifications are set by the operation on the user side. The setting method will be described below.
When the MUTE button 248 is pressed and held while the power is on, the control unit 10 executes control to display the setting menu. The left figure of FIG. 54 is an illustration of the items of the setting menu, and the right figure is an example of the display screen during the selection operation of the setting menu.

The setting menu includes (1) Easy mode setting, (2) Mode setting, (3) Alarm setting, (4) Screen / LED setting, (5) Audio setting, (6) System setting, (7) OBD setting. There is each setting menu of, and there is also a menu for completing the setting. The control unit 10 changes the selected menu according to the operation of the ▲ button 242 and the ▼ button 244, and executes the control to display the setting screen corresponding to the selected menu when the MUTE button 248 is operated. .. The figure on the right is the display screen when the easy mode setting menu is selected, and the current settings are displayed under the easy mode setting menu (normal mode is set in the figure). Has been).

(1) Easy mode setting When the easy mode (easy setting mode) is set to on as shown in Fig. 55, the simple setting mode is set only for the easy setting, and the easy setting becomes possible. When the handy mode is on, the control unit 10 significantly limits the selectable setting menus as shown in the left figure of FIG. 55. The simple settings are very simple, as you can change the brightness of the display screen and the type of radar alarm sound (electronic sound / voice), and you can only browse the software version.

(2) Mode setting Radar detector 1 has four preset alarm modes (normal, minimum, special, and all-on), as well as a manual mode. The alarm mode of your choice can be set by user operation. The normal mode is an alarm mode with settings that emphasize balance. The minimum mode is an alarm mode in which only the minimum items are set to on. The special mode is an alarm mode with settings that emphasize items related to crackdown. The all-on mode is an alarm mode in which all functions are set to on. The manual mode is an alarm mode in which each function can be set individually.

When the MUTE button 248 is pressed and held while the standby screen (upper left figure) is displayed as shown in FIG. 56, the control unit 10 switches to the setting screen (upper right figure) display. When << mode >> in the setting menu is selected, the control unit 10 switches to the display of the mode screen (lower left figure). After the preferred alarm mode is selected, when the setting end is selected (lower right figure), the control unit 10 executes control to return to the state where the original standby screen is displayed. The contents of each alarm mode are as shown in FIG. 57.

(3) Alarm setting In the alarm setting, as shown in FIG. 58, each item of reception sensitivity mode, road selection, display switching distance, target information, and notification display can be set.
In the reception sensitivity mode, one of "City" suitable for urban areas, "Extra" suitable for suburbs and highways, and "AAC / ASS" in which unnecessary alarm cut and optimum reception sensitivity are automatically set can be selectively set.

In the road selection, the target road for GPS warning can be selected from "general road", "expressway", "ALL", "AUTOGPS priority", and "AUTO atmospheric pressure priority". In the "General road" setting, only the target of the general road is warned. In the "Highway" setting, only the highway target is alerted. The ALL setting alerts all targets on open roads and highways. The setting of << AUTOGPS priority >> is a setting in which the GPS position information is preferentially used and the control unit 10 automatically identifies the type of the traveling road (general road or expressway). The setting of << AUTO atmospheric pressure priority >> is a setting in which the change in atmospheric pressure is preferentially used and the control unit 10 automatically identifies the type of the traveling road (general road or expressway). The control unit 10 executes a control that warns only the target of the general road when it can be identified as a general road, and warns only the target of the highway when it can be identified as a highway. Other setting items are as shown in the figure.

As the display switching distance, any one of << no switching >>, << 500m >>, << 1000m >>, and << 1500m >> can be selectively set. If you set the display switching distance, as explained in "6. Warning screen", when the distance from your vehicle to the target becomes short, you can switch the display from the preset standby screen to the notification panel screen, etc. Can be executed. For example, in the two-screen warning of FIG. 42, when << radar scope >> is set for the left screen 15L and << display switching distance → set 1000m >> and << target information → notification panel >> are set for the right screen 15R, control is performed. The unit 10 executes a control to display the notification panel screen including the target information telop 41 instead of the standby screen when the distance to the target reaches 1000 m. The initial setting of the display switching distance is << 1500 m >>.

(4) Screen / LED setting In the screen / LED setting, as shown in FIG. 59, each item of screen brightness, presence / absence of screen inversion, screen color setting, LED mode, and LED brightness can be set. For example, the screen brightness can be selectively set from "minimum", "dark", "normal", and "bright". As for the LED mode, any one of "alarm / touch ON", "always ON", and "OFF" can be set. Other setting items are as shown in the figure.

Here, the contents of each setting of the LED mode will be described with reference to FIG. 60. As described above, there are three types of LED mode settings: "alarm / touch ON", "always ON", and "OFF". The figure is a diagram for explaining the operation contents of the white LED 315B for each operation state of the states 1 to 3 for each of these three types of settings (control mode).

In the LED mode of << alarm / touch ON >>, the control unit 10 executes the following control. In the standby state of the state 1, each white LED 315B is normally controlled to the off state (OFF state). When the screen 15 is touched or held over the screen area 15A (FIG. 1), the control unit 10 controls the white LEDs 315B of all the operation buttons 24 to be lit. The touch operation on the screen 15 is detected by the touch area 151S of the touch screen sheet 151. The operation of holding the hand over the screen area 15A (FIG. 1) is detected by the proximity sensor 125 (FIG. 28) arranged in the gap 152S (FIG. 20) of the liquid crystal display 152L and R.

In both the hand-holding operation for turning on the white LED 315B and the hand-holding operation for muting the audio output in the standby state, the detection state of the human body or the like by the proximity sensor 125 continues for a predetermined duration. When this is done, the control unit 10 determines that there is an operation. As a predetermined duration, 1 second is set as described above for the mute hand holding operation. For the hand-holding operation in the standby state, for example, it is preferable to set a time shorter than 1 second. Regarding the mute hand holding operation, it is necessary to avoid the possibility that the hand that operates the car audio etc. is erroneously detected and the alarm voice etc. is muted, while the hand holding operation in the standby state is slow. This is because it is necessary to give priority to the operation response so as not to give an unpleasant impression.

When any of the operation buttons 24 is touch-operated after the hand-holding operation or the like is performed in the standby state (state 1) as described above, the control unit 10 switches the white LED 315B only to the operated operation button 24. A control is executed to turn off the light and return it to the lit state when the touch operation is completed. After that, when the non-operation period in which none of the operation buttons 24 is operated exceeds a predetermined time, the control unit 10 executes control to switch all the white LEDs 315B to the off state. Instead of this example, when the touch operation is completed, the operation button 24 may be blinked for a predetermined time. It becomes easier for the user to understand that the operation has been accepted.

In the state 2 hit during the alarm, the control unit 10 executes control to blink all the white LEDs 315B. If there is a direction such as the left side, the right side, or the front of the traffic monitoring activity position (implementation point) subject to the warning, for example, only the white LED 315B on the left side may blink, or only the white LED 315B at the top two places It is also effective to execute control such as blinking.
During the alarm, for example, it is also possible to execute a control for blinking all the white LEDs 315B according to the degree of attention (the degree of necessity of notification) of the alarm target. By slightly changing the lighting timing of the operation buttons 24 arranged at five locations on the outer circumference of the screen area 15A, it is possible to execute control so that the lighting position orbits around the screen area 15A during an alarm. good. Further, the higher the degree of attention, the faster the orbiting cycle may be to produce a sense of urgency. Alternatively, when entering an area where traffic accidents occur frequently, it is also possible to sensuously express a high-risk situation by randomly lighting five operation buttons 24.

In the state 3 when the power is turned on in response to the on-switching of the vehicle ignition, the control unit 10 executes a control for blinking all the white LEDs 315B, and then executes a control for turning off all the white LEDs 315B when a predetermined time elapses. It should be noted that the blinking of the white LED 315B is realized not by the complete periodic switching of on / off, but by the control of periodically changing the brightness. According to the control that periodically changes the brightness, it is possible to execute blinking of light like a firefly (the blinking cycle should be faster than that of a firefly), and it is possible to produce a sense of luxury of the device.

In the << always ON >> LED mode, the control unit 10 executes control to light each white LED 315B in the standby state (state 1), and is in an alarm (state 2) or when the power is turned on (state 3). The control for blinking the white LED 315B is executed.

In the LED mode of << OFF >>, the control unit 10 executes a control (blinking control) for blinking the white LED 315B when the power is turned on (state 3), and controls the white LED 315B to be turned off in other states.

(5) Voice setting The voice setting is a setting related to an output mode (output mode) of various sound information such as a voice such as an alarm voice and a sound effect. In the voice setting, as shown in FIG. 61, each item such as speaking speed (speaking speed), narrator switching, radar alarm sound, positioning announcement, RELAX chime, time signal, operation sound, and target approaching sound can be set. The speech speed can be switched in four stages: "slow", "normal", "fast", and "alarm interlocking". In particular, in << alarm interlocking >>, the speaking speed changes depending on the type of alarm. In narrator switching, the alarm voice can be switched between "female" and "male". With the radar alarm sound, the alarm when the radar is received can be switched between "voice" and "electronic sound".

In the positioning announcement, you can select to turn the positioning announcement on or off. For example, if the GPS signal reception condition is not good, such as in a valley of a building, the positioning announcement may be repeated as "GPS cannot be received" or "GPS has been received", but if the positioning announcement is turned off, such repetition will be repeated. It can be avoided. The RELAX chime is a function that encourages breaks at regular intervals, and says, "I'm driving for a long time. Would you like to take a break?" ] And the time interval for audio output can be selected. The time signal is a function of notifying the time every hour and on the hour, and it is possible to select the presence or absence of the time signal. As for the operation sound, it is possible to set whether or not to generate a confirmation sound when the button is operated. The target approaching sound is an output sound when the target is approaching, and the target approaching sound is output according to the on setting.

As described above, the voice setting speaking speed (FIG. 62) can be selectively set to any one of four types: "slow", "normal", "fast", and "alarm interlocking". When << normal >> is set, the control unit 10 outputs the alarm voices of all notifications at a speaking speed of 100% (average speed). When << Slow >> is set, the control unit 10 outputs the alarm voices of all notifications at a speaking speed of 90%. When << fast >> is set, the control unit 10 outputs the alarm voices of all notifications at a speaking speed of 120%.

The speaking speed of 100% means a normal speaking speed, and the speaking speed of 120% means that the speaking speed is 120%. In the radar detector 1 of this example, the voice data obtained by digitally recording the actual utterance by the narrator is recorded in the database 100. The voice data of the database 100 is record data corresponding to a speaking speed of 120%. When the voice data is reproduced as it is, the speaking speed becomes 120%. When the voice data is played back about 20% slower, the talking speed becomes 100%, and when played back further slower, the talking speed becomes 90%.

In the radar detector 1 of this example, the data size of the voice data stored in the database 100 is reduced by recording the voice data corresponding to the speech speed of 120% in the database 100. As a matter of course, the voice data corresponding to the speaking speed of 100% may be recorded in the database 100, or the voice data exceeding the actually output speaking speed such as the speaking speed of 130% may be recorded in the database 100.

When << alarm interlocking >> is set, the control unit 10 changes the speaking speed according to the type and situation of the traffic monitoring activity to be alarmed, as shown in FIG. 62. In the figure, the stealth notification and the RD notification are the (1) alarm operations when the crackdown radio waves are received, which are explained in "7. Alarm operation". The stealth notification is an alarm operation when a stealth wave is received, and the RD notification is an alarm operation when a radar wave is received. The Orbis notification, the inspection / control notification, and the My Area notification are 2) alarm operations when the target approaches in "7. Alarm operation". In the figure, "all sound effects" (fourth row from the bottom) in the notification content column is the sound effect in the phrase "(sound effect) stealth reception stealth reception" in the phrase example column. It means (for example, sound effect). For example, in the case of stealth notification, the control unit 10 outputs the phrase "stealth reception stealth reception" at a speaking speed of 120%, following the output of the sound effect at 100% speed.

For example, in the case of RD notification, the control unit 10 outputs a phrase such as "Please pay attention to the speed" after the output of the sound effect at 100% speed. At this time, the control unit 10 changes the speaking speed of a phrase such as "Be careful about speed control" according to the radar wave reception level (L1 to 5). For example, in the case of reception level 1 or 2, since the degree of caution is not so high, the control unit 10 outputs the sound effect at 100% speed, and then the phrase "Be careful about speed control". Is output at 90% speaking speed. In the case of reception level 3, the control unit 10 outputs the phrase "Be careful of speed" at 100% speaking speed, following the output of the sound effect at 100% speed. In the case of reception level 4 or 5, since the degree of caution is high, the control unit 10 says "Be careful when driving" or "Let's slow down" following the output of 100% sound effect. Output the phrase at 120% speaking speed. The control unit 10 outputs an alarm voice every time the reception level changes, such as reception level 2 → 3.

The reception levels 1 and 2 for setting the speaking speed of the latter phrase to 90% correspond to the reception level from a radio wave generation source such as an automatic door. In the radar detector 1, the speaking speed is suppressed to less than 100% because there is a possibility of false alarm for the RD notification at such a reception level.

The control unit 10 controls the speed of the sound effect to be 100% constant regardless of the speaking speed of the following phrase. In this way, if the output mode of the sound effect that triggers the alarm operation is set to exactly the same specifications regardless of the speaking speed of the phrase, the sound effect that means the start of the alarm operation can be strongly impressed on the user side, and the alarm can be made. Has the effect of suppressing the risk of being overheard.

By changing the speaking speed of the phrase as described above, the impression on the user side of the utterance can be changed. For example, if a fast speaking speed is set, it is possible to give the impression that the degree of attention is high by producing a sense of urgency. In this example, the degree of caution is defined according to the type of traffic monitoring activity to be alerted, and the display color of the target icon is set according to the degree of caution (FIG. 41). It is also good to change the speaking speed according to the display color of the target icon. For example, for traffic monitoring activities with low attention and the display color of the target icon is green, it is also good to always set a slow speaking speed and apply a control such as not changing the speaking speed.

For example, in the case of Orbis notification, the control unit 10 changes the speaking speed according to the distance to Orbis and the presence or absence of overspeed. The shorter the distance, the faster the speaking speed of the phrase following the sound effect, and in the case of overspeed, the speaking speed of the phrase is set faster than in the case of not overspeeding.
For example, in the case of an inspection / control notification, the control unit 10 changes the speaking speed of the phrase according to whether the vehicle speed is 52 km / h or more or less. When the vehicle speed is 52 km / h or more, the speaking speed is faster than when the vehicle speed is less than 52 km / h.

For the target approaching sound (distance-linked orbis sonar sound shown in FIG. 63) of the voice setting, << on >> and << off >> can be selectively set. When the target approaching sound is set to << on >>, the control unit 10 outputs a sonar sound when the orbis approaches as shown in the figure. The control unit 10 executes the Orbis notification when the distance to the Orbis is 1 km or 2 km, and then outputs the Orbis sonar sound with a transmission cycle of 1 Hz if there is no other notification. At this time, the volume of the orbis sonar sound is set to minus 8 dB with respect to the volume of the orbis notification. When the distance to the Orbis is 800 m and there is no other notification, the control unit 10 changes the transmission cycle of the Orbis sonar sound to 1.25 Hz.

In this way, the control unit 10 gradually increases the transmission cycle of the orbis sonar sound according to the distance, increases it to 2.5 Hz when it reaches 200 m, and then ends the output of the orbis sonar sound according to the passage of the orbis. .. By changing the transmission cycle of the orbis sonar sound in conjunction with the distance to the orbis in this way, the degree of attention can be grasped only by the orbis sonar sound. Even if you miss the distance from the Orbis announcement, you will be able to grasp the degree of distance from the Orbis sonar sound.

(6) System settings As shown in FIG. 64, various system settings can be made in the system settings.
(7) OBD setting In the OBD setting, as shown in FIG. 65, it is possible to set each item of the OBD meter for each screen 15, fuel consumption information, coefficient correction, and data erasure. When the OBD meter is set, the vehicle information to be displayed includes vehicle speed, engine speed, engine load, throttle opening, fuel level, intake manifold pressure, cooling water temperature, intake air temperature, outside temperature, engine oil temperature, instantaneous fuel consumption, You can selectively set either the average fuel consumption or the fuel consumption this time. For example, for the OBD meter, it is possible to select whether or not to set the OBD meter on each of the left and right screens 15L and R. Other items are as shown in the figure.

The radar detector 1 of this example configured as described above includes screens 15L and R for displaying monitoring information related to traffic monitoring activities. For example, it is possible to realize a two-screen warning display pattern in which a radar scope screen is displayed on one screen 15 and a telop is displayed on the other screen 15. In this display pattern, in addition to the radar scope screen, a telop indicating the type of traffic monitoring activity is displayed on the notification panel screen, thereby suppressing the amount of information displayed on the radar scope screen and making the monitoring position information easy to understand. Is improving. By using the plurality of screens 15L and R in this way, the monitoring information can be notified in an easy-to-understand manner.

Further, in the radar detector 1, it is possible to control the operation area of the operation button 24 to blink. By blinking the operation button 24, it is possible to effectively attract the user's attention by causing the movement of changing the brightness. If the user's attention can be attracted, it is possible to suppress the possibility that the monitoring information to be notified is not recognized by the user and is lost.

The radar detector 1 changes the output mode of sound information such as an alarm voice according to the degree of attention (the degree of necessity of notification) of the monitoring information to be notified. By changing the output mode of the sound information according to the monitoring information, it is possible to increase the amount of information that can be output as compared with the case where the sound information is output in exactly the same output mode. For example, if the speaking speed is changed, information such as a difference in attention can be notified. In addition, if there is a difference in the output mode of sound information, the user can intuitively recognize it.
As described above, the radar detector 1 of this example has excellent characteristics that can easily notify the monitoring information regarding the traffic monitoring activity.

In the radar detector 1, a housing structure in which ribs are housed in slit holes provided on the outer periphery of the substrate is realized. In this accommodating structure, a contact structure between the outer peripheral surface of the rib and the inner peripheral surface of the slit hole of the substrate is realized. If such a contact structure is provided, it can be expected that the rigidity (particularly the torsional rigidity) of the housing (case body 2) can be improved by utilizing the strength of the substrate. The rib may be erected on the bottom surface without being connected to the inner peripheral side surface of the case 22. The through hole on the substrate side that accommodates such ribs may be a closed hole that does not open on the outer periphery.

In the radar detector 1 of this example, the screens 15L and R are arranged flush with each other. Instead of this configuration, the positions of the screens 15L and R may be changed in the thickness direction (depth direction) of the case body 2. For example, the screen 15R may be arranged on the back side of the screen 15L. Further, the screen 15L and the screen 15R may be arranged so as to overlap each other in the depth direction, and the screen 15 on the front side may be formed transparently. In this case, image information with a sense of depth can be displayed by two screens overlapping in the depth direction.

Further, the screens may be arranged on different surfaces of the dice-shaped housing. Further, it is also good to adopt a bracket that rotatably supports the housing. In this case, the image information visible from the user side can be switched according to the orientation of the dice-shaped housing.

Regarding the front surface of the case body 2, it is also possible to raise the center in the left-right direction and position it on the front side in the depth direction, and to form an inclined surface so as to be located on the back side in the depth direction toward both left and right sides. If screens are installed on slopes formed on both sides of the center in the left-right direction, for example, when a radar detector is installed in the middle of the dashboard, one screen faces the driver and the other. The screen of is now facing the passenger side of the passenger seat, and the visibility of the driver and the passenger can be compatible. In this case, the same display screen may be displayed on each screen. In addition, when the orientations (normal directions) of the screens are different in this way, for example, in a situation where the sunlight is reflected on one screen, there is a possibility that the reflection of the sunlight on the other screen can be avoided. It gets higher.

In the radar detector 1 of this example, the operation buttons 24 by the operation unit 315 provided with the white LEDs 315B are arranged on the left and right sides of the screen area 15A in which the screens 15L and R are arranged. For example, the orientation of the target may be indicated depending on which operation button 24 is turned on or blinks. For example, if the target is on the left with respect to the traveling direction of the vehicle, the left operation buttons 241 and 243 may be blinked, and if the target is in front, the upper left and right operation buttons 241 and 242 may be blinked. .. If the direction is indicated by blinking the operation button 24 or the like, it is possible to realize an easy-to-understand notification that the user can grasp the direction at a glance.

Further, in the radar detector 1, five operation buttons 24 are arranged so as to surround the screen area. By using the five operation buttons 24 on the outer circumference of the screen area, for example, it is possible to control the operating buttons 24 in the lit state to orbit around the screen area 15A. For example, when an alarm is executed for a traffic monitoring activity, the cycle of orbiting the lighting position may be changed according to the degree of caution, and the higher the degree of attention, the faster the orbit may be. In this case, the user can recognize the attention level at a glance.

The easy mode of the radar detector 1 of this example is a simple setting mode in which the standby screen of each screen 15 cannot be selected. Under the easy setting, the radar scope screen is displayed on the left screen 15L, the clock screen as the standby screen is displayed on the right screen 15R, and when the distance to the target reaches a predetermined distance, it is displayed at the top of the clock screen. The telop 41 is displayed (FIG. 43). In this way, the display screen of each screen 15 is fixed under the simple setting of this example, but for example, an intermediate easy setting mode that allows you to selectively set 2 to 3 types of standby screens has been added. It is also good to do. The simple settings in this example are not enough, but the mode in which all settings can be made is too complicated to meet user needs. While the display screen of the left screen 15L is fixed to the radar scope screen, the standby screen may be selected for the right screen 15R.

In addition, the radar detector 1 of this example has a touch sensor for detecting a touch operation corresponding to each operation button 24, and also has a proximity sensor for detecting a hand-held operation or the like. I have. Capacitive touch sensors may be adopted for each operation button 24, and the hand-holding operation may be detected by using these touch sensors. In this case, the detection distance of the touch sensor may be changed between the state of waiting for the hand holding operation and the state of waiting for the touch operation. For example, while the detection distance is set long in the state of waiting for the hand-holding operation, if the detection distance is brought close to zero after the detection of the hand-holding operation, the touch operation for each operation button 24 can be detected with high certainty.

It is also possible to navigate the operation by sequentially lighting the operation buttons 24 to be operated next by utilizing the configuration in which the lighting of each operation button 24 can be individually controlled. For example, various setting contents such as "set a two-screen warning" and "set a speech speed linked with an alarm" are displayed in a selectable list, and when any of the setting contents is selected, the setting is set. It is also possible to turn on the operation buttons 24 to be operated in order to perform the operation. In this case, the user can make a desired setting simply by operating the lit operation buttons 24 in order.

It is also possible to include a map display function in the radar detector 1 of this example. It is also possible to display a map in which the target icon is plotted on one screen and display a telop displaying the information of the target icon on the other screen. Further, for example, it is also possible to display maps having different scales on a plurality of screens. A wide range map display is suitable for grasping the positional relationship between the target and the own vehicle, and a narrow range map display is suitable for grasping the distance to the target with high accuracy. Further, for example, the target icon in which the implementation point is specified may be displayed on the map on one screen, and the target in which the area is specified may be displayed on the map on the other screen. In general, plotting on a narrow map is suitable because it is necessary to display the position pinpointly for the target whose implementation point is specified, while showing the entire area for the target with the specified area. Extensive map display is suitable because it is necessary.
