Description

The present invention relates to a system for assisting the driving of a vehicle by providing information on various traffic surveillance activities such as traffic enforcement and inspections.

2. Description of the Related Art Conventionally, as a system for supporting driving of a vehicle, an in-vehicle device such as a radar detector has been realized that issues an alarm when receiving a radar wave for speed control to call the driver's attention. Such an in-vehicle device has a GPS function for measuring the current position of the vehicle and a database of GPS targets such as installation points of a speed control system, and detects an approach to a specific GPS target. There are some that notify the driver (see, for example, Patent Literature 1). According to such an in-vehicle device, it is possible to prevent the driver from unknowingly driving too fast by notifying the driver of the approaching point of the traffic monitoring activity.

The GPS targets for which the in-vehicle device with the above configuration notifies the approach are the points where the speed control system is installed, permanent points such as police stations, and traffic surveillance activities such as speed control by mobile orvis and drinking checks are frequently performed. There are temporary points etc. In-vehicle devices are trying to increase the driver's awareness of safe driving by reporting the approach to various GPS targets.

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

However, the conventional in-vehicle device described above has the following problems. In other words, while there are users who require a large amount of information such as the type of traffic monitoring activity to be warned, the implementation location, and the distance to the implementation point, they feel that the warning is difficult to understand because the amount of information presented is too large. There are also quite a few users.

SUMMARY OF THE INVENTION The present invention has been made in view of the conventional problems described above, and is an invention for providing a system capable of reporting monitoring information relating to traffic monitoring activities in an easy-to-understand manner.

A first aspect of the present invention is a system for announcing surveillance information related to traffic surveillance activities, comprising:
a plurality of displays having screens;
a control means for obtaining monitoring information relating to traffic monitoring activities and for executing control to display the monitoring information on the screen of at least one of the displays.

A second aspect of the present invention resides in a program for causing a computer to implement the functions of the system of the first aspect.

A system according to the present invention comprises a plurality of displays for displaying surveillance information relating to traffic surveillance activities. If monitoring information is displayed using a plurality of displays, the amount of display information per display can be reduced, and easy-to-understand monitoring information can be notified.

The number of displays included in the system according to the present invention may be two, or may be three or more.
The system according to the present invention may be used, for example, for in-vehicle applications, or may be used for applications other than in-vehicle applications.
The control means provided in the system of one preferred aspect of the present invention displays monitoring position information indicating the implementation point of the traffic monitoring activity on any one of the displays, and displays the type of traffic monitoring activity on any other display. It is possible to execute control to display the monitoring type information.
In this case, a display for displaying the monitoring position information and a display for displaying the monitoring type information are separately provided, so that each information can be displayed in an easy-to-understand manner. For example, in the case of plotting and displaying the implementation points on a scope surface imitating a map, radar scope, etc., the size of the map, scope surface, etc. is very important in order to grasp the monitoring position information. Since there is no need to display the monitoring type information superimposed on the map or scope surface, or to secure a place by narrowing the map or scope surface 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 according to a preferred aspect of the present invention displays a scope plane representing a predetermined area around the vehicle on any one of the display devices, and displays an icon representing a point at which traffic monitoring activities are performed on the scope plane. plotted on the surface,
It is possible to execute control to display character information representing the type of traffic surveillance activity associated with the icon plotted on the scope surface on any of the other displays.
In this case, the positional relationship between the own vehicle and the implementation point can be displayed in an easy-to-understand manner using any one of the display devices. Furthermore, by displaying the character information on any of the other displays, the type of traffic surveillance activity can be displayed in a highly visible manner.

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

A system according to a preferred aspect of the present invention includes at least two setting modes that differ in the number of types of display screens that can be selected as setting modes for selectively setting the types of display screens to be displayed on the plurality of displays. is provided, and an operating means for selecting one of the setting modes is provided.

In a system with a plurality of displays, the user has a very high degree of freedom in setting. If you are a user who enjoys using such a system, advanced settings can be made. On the other hand, users who place importance on basic functions rather than how to use the system may find it difficult to use due to the high degree of freedom in setting. Therefore, if multiple types of setting modes with different degrees of setting freedom are provided as described above, it will be possible to select the degree of setting freedom according to the user's preference, and a wide range of user needs from heavy users to general users. can handle.

The setting mode in the system of a preferred embodiment of the present invention includes a setting mode in which the type of display screen to be displayed on the plurality of display devices can be selectively set, and the display screen to be displayed on the plurality of display devices. A simple setting mode is included in which the type is defined in advance and the display screen type cannot be changed.
If a simple setting mode is provided, it will be possible to use the basic functions immediately after purchase, and a user-friendly system that can be introduced relatively easily can be realized. After that, when the need arises to use it more deeply through use, the setting mode that enables detailed settings can be selected.

In a preferred embodiment of the system of the present invention, a gap is provided between at least any two of the plurality of indicators that are arranged side by side, and a detection sensor that detects an approaching human body is included in the system. placed in the gap.
A detection sensor arranged between adjacent displays is suitable for detecting, for example, an operation of holding a hand over the screen. If 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 the operational feeling of holding the hand over the screen. Even if there are a plurality of display devices, adjacent screens are likely to be visually recognized as one screen. By arranging the detection sensor in the gap, it is possible to realize an operation feeling as if operating by holding a hand over the screen.

A preferred embodiment of the system of the present invention includes an operation unit having illumination means for lighting an operation area,
The control means can execute control for switching the operation area to a lighting state in response to detection of a human body by the detection sensor.
In this case, it is possible to realize a novel operation feeling that the system is activated by holding the hand or the like. It is possible to realize the joy of operation as if operating with hand power.

A preferred embodiment of the system of the present invention includes an operation unit having illumination means for lighting an operation area,
The control means can execute blinking control for alternately switching between a lighting state and a lighting-out state or a dimming state for the operation area.
By executing the blinking control, it is possible to make a specific operation area stand out. Furthermore, for example, it is also possible to change the cycle of blinking control. For example, it is also possible to speed up the cycle and express information to the effect that the situation is urgent. For example, blinking control may be performed for a plurality of operation areas and the phase of the blinking control may be changed to realize control such that light moves between the plurality of operation areas. In this case, a two-dimensional movement of moving light can be produced, and visual enjoyment can be produced.

A control unit included in a system according to a preferred aspect of the present invention acquires a degree of notification necessity for the monitoring information, and changes a cycle of blinking the operation area according to the degree of notification necessity.
For example, if the cycle is made faster as the degree of need for notification increases, it is possible to intuitively convey that the situation is urgent, and to present information that is easy to understand at a glance.

In a preferred embodiment of the system of the present invention, an operation unit having illumination means for lighting the operation area is provided on both the left and right sides of the area where the screens of the plurality of display devices are arranged,
The control means can execute control for notifying the direction of the traffic monitoring activity implementation point depending on which one of the operation units arranged on the left and right sides has an operation area to light up.

In this case, the direction of the implementation point can be reported using the operation unit. Notification of the azimuth by lighting the operation unit is an extremely simple notification method, and can be information that the user can intuitively grasp at a glance. Furthermore, if the operation unit can be used to notify the direction of the implementation point, for example, the need to display the direction on the display side is eliminated. The amount of information to be displayed on the display can be reduced, and the display by the display can be configured to be easier to understand.

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

In a preferred aspect of the system of the present invention, at least one of the plurality of displays has a screen that is substantially parallel to the screens of the other displays, but is not in the same plane and has different positions in the depth direction. ing.
In this case, the display can have a sense of depth. While the information that can be displayed on the screen is planar two-dimensional information, if a plurality of display devices with different positions in the depth direction are used, it is possible to give a sense of depth to the displayed information. For example, it is possible to display important information on the display on the near side and display less important information on the display on the back side. In this case, the user can intuitively recognize important information.

■ 1. Shape ■
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). be. This radar detector 1 can be installed on the back side of the sun visor, the back side of the room mirror, etc. according to the change of the bracket 28. - 特許庁The radar detector 1 can also be used with the bracket 28 removed. When the bracket 28 is removed, it is also possible to use the adhesive strength of double-sided tape or the like attached to the bottom surface of the case body 2 to directly place and install it on the dashboard or the like.

A screen area 15A (FIG. 1) in which two 1.8-inch color screens 15L and R are arranged side by side in the left-right direction (horizontal direction) is formed on the front (front) of the radar detector 1 (FIG. 1). Label areas 210 printed with the model number and model name of the radar detector 1 are provided above and below the boundary between the left and right screens 15L and R so as to cut 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. A ▲ button 242, ▼ button 244 and a MUTE (mute) button 248, which are volume adjustment buttons, are arranged on the right outer side of the screen 15R on the right side as viewed from the driver. A MEMO button 241 and a VIEW button 243 are arranged on the left outer side of the left screen 15L.

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 of the case body 2 when viewed from the driver's side. A USB connector 252, a power switch 253, a mounting portion 258 for the bracket 28, and the like are provided on the lower back surface of the case body 2. As shown in FIG. The USB connector 252 is connected to a cigar plug cord extending from the cigar socket of the vehicle, an OBD adapter (FIG. 13), a USB cable, and the like. 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 OBD (On-board Diagnostics)-II (II is Roman numeral "2", hereinafter referred to as "OBD"), which is a vehicle inspection standard. It is a communication cable connected to the OBD connector. This OBD connector, 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 housing 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 shown in FIGS. 14 and 15 is a horizontally long sheet that is arranged near 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 in the horizontal direction of the touch screen sheet 151 (FIG. 15), forming a narrow portion that is narrow in the vertical direction. It is The touch screen sheet 151 provided with this 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 columns on the left and right sides of the screens 15L and R, respectively. It should be noted that, instead of the configuration of this example, it is also possible to provide a touch area between the left and right two rows of touch areas 151S. By providing three rows of touch areas on the screen 15 in this manner, 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, and a so-called flick operation can be detected. be possible.

At both ends of the touch screen sheet 151, characters such as MEMO and watermarks 151V in triangular shapes (▴ 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 in FIGS. 16 and 17 has a shape similar to that of a frame provided with openings 218 . The opening 218 is an opening for arranging two liquid crystal displays (displays) 152L and R mounted on the first substrate 31 . Through holes 29 are formed in the frame portion of the front frame 21 at positions corresponding to the operation buttons 24 . Note that the through hole 29 on the left side of the front face lacks one side surface in the circumferential direction and forms an incomplete hole that communicates with the opening 218 .

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

Label areas 210 projecting from the outer peripheral side toward the opening 218 side are formed on the upper and lower sides of the front surface of the front frame 21 . The upper label area 210 is formed to protrude downward in the vertical direction, and the lower label area 210 is formed to protrude upward in the vertical direction. Each label area 210 is formed to be raised by the thickness of the touch screen sheet 151 with respect to the bottom surface of the recessed portion 210A. 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 in 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 positioned in the middle portion of the case body 2 in the left-right direction, it is not necessary to start attaching the touch screen sheet 151 from either the left or right end. For example, it is possible to start pasting from either the top or the bottom.

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

If the touch screen sheet 151 starts to be pasted on both sides in the left and right direction from around the middle, the distance from the start of pasting to the end of pasting is approximately halved, so the deviation that occurs at the left and right ends is reduced. Also, for example, it is possible to start attaching 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 angular misalignment when the attachment is started from the upper side, there is little possibility that a large misalignment will occur on the lower side.

On the back side of the front frame 21 (see FIG. 17), screw posts 213 are erected at the four corners, and two screw holes 211 are drilled at the top and bottom. A seat portion is formed on the outer periphery of the screw hole 211 to abut on the first substrate 31 . A cylindrical portion extends from the through hole 29 corresponding to each operation button 24 , and the end surface of the cylindrical portion is flush with the seat portion of the screw hole 211 so that the first substrate 31 can be contacted. ing.

A seat portion 213</b>A extending linearly in the radial direction is provided on the outer peripheral side of the screw support 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 at a circumferential position corresponding to the outer peripheral side of the front frame 21 in the horizontal direction. For example, a lower right screw post 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 rightward. The seat portion 213A is formed to be lower in height than the screw post 213, and this height difference is substantially the same as the thickness of the second substrate 32 (slightly smaller than the thickness of the substrate 32).

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

The end face of the support 221 forms a seat that abuts on the second substrate 32 . Further, each hole such as the speaker hole 254, the switch hole 253H, the USB connector hole 252H, etc. is provided with a cylinder or a seat (hereinafter referred to as cylinder or the like). Furthermore, a seat portion 226 is also provided in the upper part inside the case 22 . The column 221, the cylindrical portion, etc., 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 column 221 and the cylindrical 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 each of the upper, lower, left and right inner peripheral side surfaces of the case 22 . Each rib 222 , 223 is erected on the bottom surface in a state of being connected to the inner peripheral side surface of the case 22 . Although details will be described later, the ribs 222 on both left and right sides are accommodated in slit holes 312 and 322 provided on the outer peripheries of the substrates 31 and 32 (FIGS. 20 and 25). The upper and lower ribs 223 are accommodated in slit holes 313 and 323 provided on the outer peripheries of the substrates 31 and 32, respectively.

The left and right ribs 222 have a constant cross-sectional shape in the depth direction of the case 22 . On the other hand, among the upper and lower ribs 223, the upper left, upper right, and lower left ribs 223 (FIG. 18) are formed so that the end face on the opening side is stepped, and the inner peripheral side is higher than the bottom face. is low (see FIG. 19). The lower end surface forming the shelf surface serves as 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 does not have a shelf surface.

In the following description, with regard to the rib 223 whose opening-side end face is formed in a stepped manner and whose projecting width is narrow at the tip, the portion on the base side is referred to as a rib body portion 223B, and the portion with the narrow projecting width at the tip is referred to as a rib body portion 223B. This is referred to as a rib tip portion 223A.

The first substrate 31 in FIG. 20 is a double-sided mounting substrate. Liquid crystal displays 152L and 152R are mounted on the mounting surface (see FIG. 20) of the first substrate 31 on the front frame 21 side (front side).

Details of each setting will be described later.

Next, the basic operation of the radar detector 1 will be explained.
The control unit 10 first displays an opening animation (not shown) when energization is started in response to switching on of the vehicle ignition. After that, a positioning information screen (not shown) is displayed until GPS radio waves from GPS satellites are received and positioning of the current position becomes possible.

When the positioning of the current position becomes possible, the control unit 10 outputs a voice saying "Positioning completed" and switches the display screens of the screens 15L and 15R to a predetermined standby screen. In addition, in the radar detector 1, it is possible to set a desired standby screen for each of the left and right screens 15L and R according to a setting operation described later.

The control unit 10 causes the left and right screens 15L and 15R to display standby screens in a standby state in which an alarm target event such as RD reception, radio reception, or approaching an alarm point has not occurred. When any one of the alarm point approach, RD reception, and radio reception events occurs in the standby state, the control unit 10 executes the corresponding function among the GPS alarm function, the RD alarm function, and the radio alarm function. Then, a warning screen is displayed on the screens 15L and 15R. When two or more events occur at the same time, the priority of each function is the RD alarm function, the wireless alarm function, and the GPS alarm function from the highest.
Further, the control unit 10 causes the white LED 315B provided in each operation button 24 to perform various light emitting operations (described later) when the vehicle ignition is switched on or when executing an alarm operation.

(9) OBD Meter Screen The OBD meter screen of FIG. 38 is a display screen that displays vehicle information acquired via the OBD adapter (FIG. 13). The OBD meter screen becomes selectable when the OBD adapter is connected. For example, when the OBD adapter is connected, when the touch area 151S on the left side of the screen 15 displaying the satellite information screen is touched, the OBD meter screen is displayed. The OBD meter screen and the next OBD fuel consumption information screen are passed without being displayed. Vehicle information that can be selectively displayed on the OBD meter screen includes, for example, vehicle speed, engine speed, engine load, throttle opening, fuel level, intake manifold pressure, cooling water temperature, intake air temperature, outside air temperature, as shown in FIG. , engine oil temperature, instantaneous fuel consumption, average fuel consumption, current fuel consumption, and the like.

(10) OBD fuel consumption information screen The OBD fuel consumption information screen of FIG. 39 is a display screen for displaying the instantaneous fuel consumption and average fuel consumption calculated by the control unit 10 using vehicle information. Since the vehicle information is acquired via the OBD adapter, when the OBD adapter is not connected, the display is not switched like the OBD meter screen. On the OBD fuel consumption information screen, two types of fuel consumption are displayed in two stages, upper and lower. Numeric display of fuel consumption and segment display of the degree of fuel consumption are arranged above and below each row. Combinations of two types of fuel consumption include a combination of instantaneous fuel consumption and average fuel consumption, a combination of instantaneous fuel consumption and current fuel consumption, a combination of current fuel consumption and average fuel consumption, and the like.
As the standby screen, in addition to the above, a calendar screen displaying the date, etc., and an OFF screen in which the screen 15 is completely dark are set (FIG. 29).

Note that the control unit 10 displays various status icons illustrated in FIG. 40 at the bottom of the standby screen. The control unit 10 normally displays status icons on the left screen 15L. However, when the left screen 15L is the radar scope screen, the OBD meter screen, or the OFF screen, a status icon is displayed on the right screen 15R. If both the left and right screens 15L and R are either the radar scope screen or the OBD meter screen, the status icon is not displayed.

Further, examples of target icons displayed on the radar scope screen by the control unit 10 include each icon illustrated in FIG. 41 . Each target icon has a different display color according to the degree of caution (degree of need for notification), and the degree of caution increases in the order of green→blue→yellow→red. The distribution of attention levels is defined in advance according to the type (content) of the traffic surveillance activity related to the target.

In some standby screens, the display color of characters can be selected from six colors prepared in advance. Furthermore, it is possible to set the standby screen to automatically switch and display each standby screen at regular time intervals (for example, one minute).

■ 6. Warning screen ■
In the radar detector 1, the display pattern of the warning screen displayed by the control unit 10 at the time of warning can be set. When the VIEW button 243 is pressed long while the standby screen is displayed, the control unit 10 switches the display to the warning screen. The display patterns of the warning screen include patterns of two-screen warning, one-screen warning 1, one-screen warning 2, and no warning screen. In each display pattern, the left and right screens 15L and R can be exchanged for display.

(1) Dual-screen warning The display pattern of the dual-screen warning is, as shown in Figure 42, a radar scope screen that displays the positional relationship between the vehicle's position and the target, and a notification panel screen that notifies the target type and distance to the target. , are displayed simultaneously. On the notification panel screen, a telop (character information) 41 displaying the target type (monitoring type information) and the distance in characters is displayed at the top, and an illustration 42 representing the target type is displayed in the center. Furthermore, the time is displayed on the lower right. The illustration 42 is displayed based on the illustration data stored in the database 100. FIG.

There are the following three methods for displaying the display pattern of the two-screen warning. The first method is to display by long-pressing the VIEW button 243 . A second method is to select <<radar scope>> for the left screen 15L and set <<display switching distance→no switching>> and <<target information→notice panel>> for the right screen 15R. Here, <<>> such as <<display switching distance→no switching>> indicates a setting item in the radar detector 1 . A third display method is to set <<radar scope>> for the left screen 15L, and set <<display switching distance→set distance>> and <<target information→notice panel>> 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 display pattern is switched to the dual-screen warning display pattern.

In the two-screen warning, the radar scope screen is displayed on one screen 15 and the notification panel screen is displayed on the other screen 15 . For example, in other radar detectors with only one screen, it is necessary to use part of the radar scope screen to display target information such as target type and distance. With dual-screen warning, target information can be displayed separately from the radar scope screen. With such a display specification, a wide display area can be secured on the scope surface on the radar scope screen, and the position of the target can be easily grasped, and the display of the target information is very easy to understand.

(2) 1-screen warning 1
The display pattern of this one-screen warning 1 is, as shown in FIG. 43, a radar scope screen that displays the position of the vehicle and the target, and a telop 41 that informs the type and distance of the target at the top of the standby screen. It's a setting. In the radar detector 1 of this example, the initial setting is the display pattern of one-screen warning No. 1 in which the clock screen is set as the standby screen.

There are two methods for displaying the display pattern of the one-screen warning 1 as follows. A first method is to set <<radar scope>> for the left screen 15L, and set <<display switching distance→no switching>> and <<target information→telop>> for the right screen 15R. A second method is to set <<radar scope>> for the left screen 15L, and set <<display switching distance→set distance>> and <<target information→telop>> for the right screen 15R. In this method, when the distance between the vehicle and the target reaches the distance set by the display switching distance, a warning screen such as that shown in FIG. 43 is switched and displayed. It should be noted that which screen 15L or 15R the telop 41 is to be displayed on can be selectively set by the user's operation.

(3) 1-screen warning 2
The display pattern of this one-screen warning 2 is, as shown in FIG. 44, a display pattern in which the standby screen is displayed on the left screen 15L and the information panel screen is displayed on the right screen 15R in the event of an alarm. This one-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 screens 15L and 15R on the left or right side the notification panel screen is displayed can be set by the setting item <<notification display>>.

(4) No warning screen As shown in FIG. 45, the display pattern without warning screen displays the standby screen on both the left and right screens 15L and R, and either the left or right screen 15 (the right screen in FIG. 15R) is a display pattern in which only a telop 41 is displayed. 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 as On which screen 15, left or right, the telop 41 is to be displayed can be set by <<notification display>>.

■ 7. Alarm action ■
(1) Warning operation when receiving a crackdown radio wave When the control unit 10 receives a crackdown radio wave such as a radar wave or a stealth wave, the control unit 10 displays a warning screen on the screen 15 and executes a warning operation such as 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 issues both a sound (electronic sound/warning 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 representing the type of traffic monitoring activity on the upper part of the radar scope screen. This telop 41 includes a display of the reception level of radio waves such as radar waves (for example, L5).

Note that when a predetermined mute operation is performed during an alarm, the control unit 10 performs control to temporarily turn off the alarm sound until the radar waves being received are 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 (one second), a long pressing operation of the MUTE button 248, and the like. Further, when the radar wave reception continues for about 30 seconds or longer, the control unit 10 automatically performs control to reduce the volume of the warning sound.
In addition, as shown in FIG. 47, the control unit 10, in the alarm operation when receiving the crackdown radar wave, electronic Execute control to raise the tempo of the sound.

(2) Warning operation when approaching a target When the distance between the vehicle and the target becomes small (when the target is approached), the control unit 10 displays a telop 41 that displays the target information and the distance in characters, as shown in FIG. It is displayed on the upper part of the screen 15.

FIG. 4(a) is an example when <<telop display>> is set for the clock screen set as the standby screen. FIG. 4(b) 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 at the lower right. FIG. 1(c) shows a change in the background color of the screen 15 controlled by the control unit 10 according to the level of alertness of the warning. FIG. 4(d) is an example when <<telop display>> is set on the notification panel screen.

(3) Warning Voice When the control unit 10 outputs a warning voice for a target located at an angle of about 25° or more to the right or left of the direction of travel (see FIG. 49), Add the phrase "right direction" and execute control to announce the direction (azimuth of the implementation point). The "right direction" and "left direction" voices are the directions of the target at the time of notification. If the distance to the target is very short, the phrase for identifying the horizontal direction may not be added. Here, "" means voice output by warning voice.

The warning voice is output at each timing shown in FIGS. 50-53. In FIG. 50, the upper row shows warning voices relating to orbis (speeding crackdown), and the lower row shows warning voices relating to the control area.
For example, in the case of the warning voice of Orvis, the stages of 2 km ahead (only on highways), 1 km ahead, 500 m ahead, just before, passing are set, and the warning 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 by voice. Furthermore, at 1 km away, in addition to the voice output of the distance, warning voices announcing speed limits and overspeeding are output, and at 500 m ahead a warning voice announcing the camera position is output. When the speed is exceeded immediately before, the control unit 10 executes control to output an alarm voice for notifying the vehicle of excessive speed in addition to the notification of the traveling speed immediately before.

For example, in the case of the warning voice for the control area, each stage of 1 km ahead, area entry, and area exit is set, and the control unit 10 controls to output the warning voice for each stage. At the stage of 1 km ahead, whether the area is in the left or right direction is also output by a warning voice. Note that while a 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/interrogation area at the bottom of the display screen.

Audio output (speech) such as an alarm voice can be muted (silenced) by holding the screen area 15A (FIG. 1) with a hand. When the proximity sensor 125 placed in the gap 152S (FIG. 20) between the left and right liquid crystal displays 152L and R detects a human body and the detection state continues for one second, the controller 10 outputs sound. 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, there is little risk of erroneous detection of the hand movement of the driver trying to operate the audio or the like by releasing his hand from the steering wheel.

■ 8. Various settings ■
In the radar detector 1, a plurality of operation specifications are prepared, and the desired operation specification is set by the user's operation. The setting method will be described below.
When the MUTE button 248 is pressed long while the power is on, the control unit 10 executes control to display the setting menu. The left diagram of FIG. 54 shows the items of the setting menu, and the right diagram shows an example of the display screen during 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) sound setting, (6) system setting, and (7) OBD setting. There is a setting menu for each setting, and a setting end menu is also prepared. The control unit 10 changes the menu being selected according to the operation of the ▲ button 242 and ▼ button 244, and executes control to display the setting screen corresponding to the menu being selected when the MUTE button 248 is operated. . The right figure in the same figure is a display screen when the setting menu of the easy mode is selected, and the current setting is displayed under the setting menu of the easy mode (in the figure, the normal mode is set). is being used).

(1) Easy mode setting When the easy mode (easy setting mode) is set to ON as shown in FIG. 55, the setting mode becomes a simple setting mode with only easy setting, and easy setting is possible. When the easy mode is on, the control unit 10 greatly limits the selectable setting menus as shown in the left diagram of FIG. Easy settings are very easy to set, as you can change the brightness of the display screen and the type of radar warning sound (electronic sound / voice), and you can only view the software version.

(2) Mode setting The radar detector 1 has four preset alarm modes (normal, minimum, special, all-on) and a manual mode. A user can set a desired alarm mode. The normal mode is an alarm mode with settings that emphasize balance. Minimum mode is an alarm mode in which only the minimum items are set on. The special mode is an alarm mode with settings that emphasize items related to crackdowns. All-on mode is an alarm mode in which all functions are set on. Manual mode is an alarm mode in which each function can be set individually.

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

(3) Alarm Setting In the alarm setting, as shown in FIG. 58, it is possible to set each item of reception sensitivity mode, road selection, display switching distance, target information, and notification display.
In the reception sensitivity mode, any one of <<City>> suitable for urban areas, <<Extra>> suitable for suburbs and highways, and <<AAC/ASS>> which automatically sets unnecessary alarms and optimal reception sensitivity can be set selectively.

In the road selection, the target road of the GPS warning can be selected from <<general road>>, <<expressway>>, <<ALL>>, <<AUTOGPS priority>> and <<AUTO atmospheric pressure priority>>. With the <<public road>> setting, only targets on public roads are warned. With the <<Highway>> setting, only highway targets are alerted. With the <<ALL>> setting, all road and highway targets are alerted. The setting of <<AUTOGPS priority>> is a setting in which GPS position information is preferentially used and the control unit 10 automatically identifies the type of traveling road (general road or expressway). The setting of <<AUTO atmospheric pressure priority>> is a setting that preferentially utilizes changes in atmospheric pressure and allows the control unit 10 to automatically identify the type of road (general road or expressway). The control unit 10 executes control to warn only the target on the general road when it can be identified as a general road, and to warn only the target on the expressway when it can be identified as a highway. Other setting items are as shown in FIG.

As the display switching distance, any distance among <<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 close, the display will switch from the preset standby screen to the notification panel screen, etc. can be executed. For example, in the two-screen warning in FIG. 42, when <<radar scope>> is set for the left screen 15L, and <<display switching distance→set 1000 m>> and <<target information→notice panel>> are set for the right screen 15R, the control When the distance to the target reaches 1000 m, the unit 10 executes control to display a notification panel screen containing target information telop 41 instead of the standby screen. The initial setting of the display switching distance is <<1500m>>.

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

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

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

In both the hand holding operation for turning on the white LED 315B in the standby state and the hand holding operation for muting the audio output, the detection state of the human body or the like by the proximity sensor 125 continues for a predetermined duration. Then, the controller 10 determines that there is an operation. As the predetermined duration, one second is set as described above for the hand holding operation for mute. For the hand-held operation in the standby state, it is preferable to set a time shorter than 1 second, for example. Regarding the hand holding operation for mute, it is necessary to avoid the risk of muting the warning voice due to false detection of the hand operating the car audio, etc. This is because it is necessary to give priority to the operation response so as not to give a negative impression.

After the hand holding operation or the like is performed in the standby state (state 1) as described above, when any of the operation buttons 24 is touch-operated, the control unit 10 turns on the white LED 315B of only the operated operation button 24. Control is executed to turn off the light and return to the lighted state in accordance with the end of the touch operation. 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, the operation button 24 may blink for a predetermined period of time when the touch operation ends. This makes it easier for the user to understand that the operation has been accepted.

In state 2 corresponding to the warning, the control unit 10 performs control to blink all the white LEDs 315B. In addition, if the location (implementation point) of the traffic monitoring activity to be warned has a directionality such as left, right, or forward, for example, only the left white LED 315B is blinked, or only the upper two white LEDs 315B are blinked. It is also effective to execute control such as blinking .
It should be noted that, during the warning, for example, it is also possible to execute control to blink all the white LEDs 315B according to the caution level (reporting necessity level) of the warning target. By slightly varying the lighting timing of the operation buttons 24 arranged at five locations on the outer circumference of the screen area 15A, it is also possible to execute control so that the lighting position circulates around the screen area 15A during an alarm. good. Furthermore, the higher the degree of attention, the faster the cycle of rotation may be to produce a sense of urgency. Alternatively, when entering an area where traffic accidents frequently occur, it is also possible to sensuously express a high-risk situation by randomly lighting the five operation buttons 24 .

In state 3, which corresponds to power-on in response to on-switching of the vehicle ignition, the control unit 10 executes control to flash all the white LEDs 315B, and then executes control to turn them all off when a predetermined time elapses. Note that blinking of the white LED 315B is realized by control of periodically changing the brightness, not complete on/off periodic switching. According to the control of periodically changing the brightness, blinking of light like firefly (it is preferable that the blinking cycle is faster than that of firefly) can be executed, and the high-class feeling of the device can be produced.

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

In the <<OFF>> LED mode, the control unit 10 executes control (blinking control) to blink 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) Sound Settings The sound settings are settings related to the output mode (output mode) of various sound information such as sounds such as warning voices and sound effects. As shown in FIG. 61, the voice setting allows setting of items such as speech speed (speaking speed), narrator switching, radar warning sound, positioning announcement, RELAX chime, time signal, operation sound, and target approaching sound. As for the speed of speech, the speed of the warning voice can be switched between four levels of <<slow>>, <<normal>>, <<fast>> and <<interlocked with alarm>>. In particular, with <<alarm linkage>>, the speed of speech changes depending on the type of alarm. In the narrator switching, the warning voice can be switched between <<female>> and <<male>>. With the radar warning sound, you can switch between "voice" and "electronic sound" when receiving a radar warning.

Positioning announcements can be turned on or off. For example, when the reception of GPS radio waves is not good, such as in a canyon between buildings, the positioning announcements such as ``Cannot receive GPS'' and ``GPS has been received'' may be repeated. can be avoided. The RELAX chime is a function that encourages you to take a break at regular intervals. It is possible to select the time interval for voice output. The hourly signal is a function of notifying the time every hour on the hour, and it is possible to select whether or not to use the hourly signal. As for the operation sound, it is possible to set whether or not to generate a confirmation sound when a button is operated. The target approaching sound is an output sound when the target approaches, and the target approaching sound is output according to the ON setting.

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

The speech speed of 100% means a normal speaking speed, and the speech speed of 120% means a speaking speed of 120%. In addition, in the radar detector 1 of this example, voice data obtained by digitally recording the actual utterance of the narrator is recorded in the database 100 . The voice data in the database 100 are record data corresponding to a speech speed of 120%. If the voice data is reproduced as it is, the speech speed becomes 120%. If the audio data is reproduced about 20% slower, the speech speed becomes 100%, and if it is reproduced further slower, the speech 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 voice data corresponding to 120% speech speed in the database 100 . Of course, voice data corresponding to a speech speed of 100% may be recorded in the database 100, or voice data exceeding the actual output speech speed, such as a speech speed of 130%, may be recorded in the database 100.

When <<alarm interlocking>> is set, the control unit 10 changes the speed of speech according to the type and situation of the traffic monitoring activity to be warned, as shown in FIG. In the figure, the stealth notification and the RD notification are (1) the alarm operation at the time of receiving the control radio wave described in "7. Alarm operation". Stealth notification is an alarm operation when a stealth wave is received, and RD notification is an alarm operation when a radar wave is received. Orbis notification, inspection/surveillance notification, and My Area notification are 2) warning actions when a target is approaching in "7. Warning Actions". In the same 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" in the phrase example column. It means (for example, po~~n, etc.). For example, in the case of stealth announcement, the control unit 10 outputs the phrase "stealth reception, stealth reception" at 120% speech speed after outputting a sound effect at 100% speed.

For example, in the case of an RD notification, the control unit 10 outputs a phrase such as "Beware of speed" after outputting a 100% speed sound effect. At this time, the control unit 10 changes the speech speed of phrases such as "Beware of speed control" according to the reception level (L1 to L5) of the radar wave. For example, in the case of reception level 1 or 2, since the level of caution is not so high, the control unit 10 outputs the sound effect of 100% speed, followed by the phrase "Beware of speed control". is output at 90% speech speed. In the case of reception level 3, the control unit 10 outputs the phrase "Please be careful of your speed" at 100% speech speed after outputting the sound effect at 100% speed. In the case of the reception level 4 or 5, since the level of caution is high, the control unit 10 outputs a sound effect of 100% followed by "Please be careful when driving" or "Let's slow down". Phrase is output at 120% speech speed. The control unit 10 outputs an alarm voice every time the reception level changes, such as reception level 2→3.

Note that the reception levels 1 and 2 at which the speech speed of the phrase in the latter half is set to 90% correspond to the reception levels from a radio wave source such as an automatic door. In the radar detector 1, the speech rate is suppressed to less than 100% because there is a possibility that an RD announcement at such a reception level may result in an erroneous alarm.

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 specification regardless of the speech speed of the phrase, the sound effect that indicates the start of the alarm operation can strongly impress the user, and the alarm is activated. is suppressed.

By changing the speaking speed of the phrase as described above, it is possible to change the user's impression of the utterance. For example, by setting a fast speaking speed, it is possible to give an impression of high attention 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 warned, and the display color of the target icon is set according to the degree of caution (FIG. 41). It is also possible to change the speech speed according to the display color of the target icon. For example, for a traffic surveillance activity with a low attention level and a green target icon, it is also possible to set a slow speech rate and not change the speech rate.

For example, in the case of an Orbis notification, the control unit 10 changes the speech speed according to the distance to the Orbis and whether the speed is excessive. The closer the distance is, the faster the speaking speed of the phrase following the sound effect is set.
For example, in the case of an inspection/enforcement announcement, the control unit 10 changes the speech 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 speech speed is made faster than when the speed is less than 52 km/h.

The target approaching sound (distance-linked orvis sonar sound shown in FIG. 63) in the audio setting can be selectively set to <<ON>><<OFF>>. When the target approach sound is set to <<ON>>, the control unit 10 outputs a sonar sound when the orvis approaches as shown in FIG. After the control unit 10 announces the Orvis when the distance to the Orbis reaches 1 km or 2 km, the control unit 10 outputs the Orvis sonar sound at a transmission cycle of 1 Hz if there is no other announcement. At this time, the volume of the ORBIS sonar sound is set to minus 8 dB relative to the volume of the ORBIS notification. When the distance to ORBIS becomes 800 m and there is no other notification, the control section 10 changes the transmission period of the ORBIS sonar sound to 1.25 Hz.

In this manner, the control unit 10 gradually increases the transmission period of the Orvis sonar sound according to the distance, and when the distance reaches 200 m, the frequency is increased to 2.5 Hz. . By changing the transmission cycle of the Orvis sonar sound in conjunction with the distance to the Orvis in this way, it is possible to grasp the degree of caution only by the Orvis sonar sound. Even if you miss the distance announced by Orvis, you can grasp the degree of distance by the Orvis sonar sound.

(6) System Settings In the system settings, as shown in FIG. 64, various system settings can be made.
(7) OBD Setting In the OBD setting, as shown in FIG. 65, it is possible to set items such as OBD meter setting, fuel consumption information, coefficient correction, and data deletion for each screen 15 . 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, Either the average fuel consumption or the current fuel consumption can be selectively set. For example, as 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 is provided with screens 15L and 15R for displaying monitoring information relating 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, reducing the amount of information displayed on the radar scope screen and making the monitoring position information easier to understand. are improving. By using a plurality of screens 15L and 15R in this manner, 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 a change in brightness. If it is possible to attract the user's attention, it is possible to suppress the possibility that the monitoring information to be notified may be overlooked without being recognized by the user.

The radar detector 1 changes the output mode of sound information such as an alarm voice in accordance with the level of caution (degree of need for notification) of 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 compared to the case where the sound information is output in exactly the same output mode. For example, if the speed of speech is changed, it is possible to notify the information of the difference in attention level. In addition, the user can intuitively recognize the difference in the output mode of the sound information.
As described above, the radar detector 1 of the present embodiment has the excellent characteristics of being able to report monitoring information on traffic monitoring activities in an easy-to-understand manner.

In the radar detector 1, a housing structure is realized in which ribs are housed in slit holes provided on the outer circumference of the substrate. In this accommodation structure, a contact structure is realized between the outer peripheral surface of the rib and the inner peripheral surface of the slit hole of the substrate. By providing such an abutting structure, it is possible to improve the rigidity (especially torsional rigidity) of the housing (case body 2) by utilizing the strength of the substrate. In addition, the rib may be configured to stand on the bottom surface without being connected to the inner peripheral side surface of the case 22 . The through-holes on the substrate side that accommodate such ribs may be closed holes that do not open to the outer periphery.

In the radar detector 1 of this example, the screens 15L and 15R are arranged in parallel on the same plane. 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. FIG. For example, the screen 15R may be placed on the back side with respect to the screen 15L. Furthermore, the screen 15L and the screen 15R may be arranged so as to overlap in the depth direction, and the screen 15 on the front side may be made transparent. In this case, two screens overlapping in the depth direction can display image information with a sense of depth.

Furthermore, it is also possible to dispose the screens on different surfaces of the dice-shaped housing. Furthermore, it is also possible to employ a bracket that rotatably supports the housing. In this case, it is possible to switch the image information visible from the user side according to the orientation of the dice-shaped housing.

The front surface of the case body 2 may be formed with an inclined surface that is located on the front side in the depth direction by raising the center in the left-right direction and located on the back side in the depth direction toward both left and right sides. If the screens are installed on inclined surfaces 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's side and the other screen The screen now faces the passenger side of the passenger seat, making it possible to achieve both visibility for the driver and the passenger. 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 sunlight is reflected on one screen, there is a possibility that the reflection of the sunlight on the other screen can be avoided. get higher

In the radar detector 1 of this example, operation buttons 24 by an operation unit 315 having a white LED 315B are arranged on both left and right sides of a 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 lit or blinked. 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 azimuth is indicated by blinking the operation button 24 or the like, it is possible to realize an easy-to-understand notification that allows the user to grasp the azimuth at a glance.

Furthermore, 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 periphery of the screen area, for example, it is possible to control the operation button 24 in the lighted state to go around the screen area 15A. For example, when a warning is issued for a traffic monitoring activity, the period of rotation of the lighting position may be changed according to the degree of caution, and the higher the degree of caution, the faster the rotation. In this case, the user can recognize the attention level at a glance.

The simple 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 simple setting, the radar scope screen is displayed on the left screen 15L, the clock screen as a standby screen is displayed on the right screen 15R, and when the distance to the target reaches a predetermined distance, the A telop 41 is displayed (FIG. 43). In this way, under the simple setting of this example, the display screen of each screen 15 is fixed, but for example, an intermediate simple setting mode is added in which two or three types of standby screens can be selectively set. It is also good to The simple settings in this example are not enough, but the mode in which all settings are possible can meet user needs that are too complicated. The display screen of the left screen 15L may be fixed to the radar scope screen, while the standby screen may be selected for the right screen 15R.

Note that 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 holding operation or the like. I have. It is also possible to employ a capacitive touch sensor for each operation button 24 and use these touch sensors to detect the hand holding operation. In this case, it is preferable to change the detection distance of the touch sensor between the state of waiting for the holding operation and the state of waiting for the touch operation. For example, if the detection distance is set long while waiting for a hand holding operation, and if the detection distance is brought close to zero after the hand holding operation is detected, a touch operation on each operation button 24 can be detected with high certainty.

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

It is also good that the radar detector 1 of this example includes a map display function. It is also possible to display a map plotted with target icons on one screen and display a telop showing information about the target icons on the other screen. Also, for example, maps with different scales may be displayed on a plurality of screens. A wide-range map display is suitable for grasping the positional relationship between the target and the vehicle, and a narrow-range map display is suitable for grasping the distance to the target with high accuracy. Furthermore, for example, it is possible to display a target icon with a specified implementation point on the map of one screen, and display a target with a specified area on the map of another screen. In general, a target with a specified location needs to be pinpointed and plotted on a narrow map, while a target with a specified area shows the entire area. A wide map display is suitable because it is necessary.
