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

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

  A card insertion slot 251 for inserting a memory card 171 (FIG. 28) such as an SD card, which is an insertable / 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 mounting portion 258 for the bracket 28, and the like are provided at the lower back of the case body 2. The USB connector 252 is connected to a cigar plug cord, an OBD adapter (FIG. 13), a USB cable, and the like that extend from the cigar socket of the vehicle. The radar detector 1 operates by receiving power supply via a cord connected to the USB connector 252.

  The OBD adapter of FIG. 13 is provided on the vehicle side in accordance with OBD (On-board Diagnostics) -II (II is the Roman numeral “2”, hereinafter referred to as “OBD”), which is a vehicle inspection standard. A communication cable connected to the OBD connector. This OBD connector, also referred to as a failure diagnosis connector, is electrically extended from a vehicle ECU (not shown) and can output various types of vehicle information. A connector that is detachably attached to the OBD connector of the vehicle is attached to the front end 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 on the front side of the case body 2 that accommodates 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 disposed 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 toward the inner peripheral side is provided at the intermediate portion in the left-right direction of the touch screen sheet 151 (FIG. 15), and a narrow portion having a narrow vertical width is formed. Has been. 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) 151 </ b> S are formed in two vertical columns on the left and right sides of the screens 15 </ b> L and R, respectively. Instead of the configuration of this example, a touch area may be provided in the middle of the touch areas 151S in the left and right columns. Thus, by providing three rows of touch areas on the screen 15, for example, a touch operation in which the touch position moves from the right touch area to the left via the center can be detected. It becomes possible.

  At both ends of the touch screen sheet 151, a watermark 151V such as a character such as MEMO or a triangular shape (▲ or ▼) is provided at a position corresponding to each operation button 24 (FIG. 1). According to the watermark 151 </ b> V of the touch screen sheet 151, the operation area of the operation button 24 can be clearly shown by transmitting the light of the white LED (illuminating unit) 137 accommodated therein.

  The front frame 21 in FIGS. 16 and 17 has a shape close to that of a frame provided with an opening 218. The opening 218 is an opening for disposing the two liquid crystal display devices (display devices) 152 </ b> L and R mounted on the first substrate 31. A through hole 29 is formed at a position corresponding to each operation button 24 in the frame portion of the front frame 21. Note that the left side through-hole 29 from the front side is an incomplete hole in which one side surface in the circumferential direction is missing and communicates with the opening 218.

  A shallow recess 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 recess 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 recess 210A along the surface of the liquid crystal displays 152L and R.

  On the upper and lower sides of the front surface of the front frame 21, label regions 210 that protrude from the outer peripheral side toward the opening 218 side are formed. The upper label region 210 is formed so as to protrude downward in the vertical direction, and the lower label region 210 is formed so as to protrude upward in the vertical direction. Each label region 210 is formed so as to be raised by the thickness of the touch screen sheet 151 with respect to the bottom surface of the recess 210A. In the assembled state in which the touch screen sheet 151 is attached to the front frame 21, a front appearance like glasses is formed by a combination of the label area 210 protruding from the vertical direction and the glossy touch screen sheet 151. ing.

  The label area 210 of the front frame 21 matches the above-described constricted shape 151D (FIG. 15) of the touch panel 151, and has a positioning shape when the touch screen sheet 151 is pasted. In the radar detector 1 of this example, since the positioning shape is located at the middle portion of the case body 2 in the left-right direction, there is no need to start attaching the touch screen sheet 151 from either the left or right end side. For example, it is possible to start pasting from either top or bottom.

  If the touch screen sheet 151 starts to be pasted from either the left or right end, and there is a shift in the angle of the touch screen sheet 151, the shift is amplified toward the opposite end and the end of the sticking. There is a risk that a very large deviation will occur. On the other hand, when the positioning shape is provided in the middle portion in the left-right direction, for example, the touch screen sheet 151 can be pasted from the middle in the left-right direction and pasted on both sides in the left-right direction.

  If the touch screen sheet 151 is started to be attached to both sides in the left-right direction from the middle, the distance from the start of application to the end of application is approximately halved. In addition, 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 vertical width of the touch screen sheet 151 is narrow, for example, even if a slight angular deviation occurs when starting to be attached from the upper side, there is little possibility that a large shift occurs on the lower side.

  On the back side of the front frame 21 (see FIG. 17), screw struts 213 are erected at four corners, and screw holes 211 are formed at two locations in the vertical direction. A seat portion that contacts the first substrate 31 is formed on the outer periphery of the screw hole 211. The through hole 29 corresponding to each operation button 24 is provided with a cylindrical portion, 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 linearly extending 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 among the left and right directions. For example, for the lower right screw strut 213 (see FIG. 17) when the front frame 21 is viewed from the back side, a seat portion 213A extending downward and a seat portion 213A extending rightward are provided. The seat portion 213 </ b> A is formed to be lower than the screw support 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 in FIG. 18 is a bottomed member that is screwed to the front frame 21. On the bottom surface of the case 22, a switch hole 253H, a USB connector hole 252H, and the like are formed. At four corners on the inner side of the case 22, columns 221 with through holes are erected.

  The end surface of the support column 221 forms a seat that abuts on the second substrate 32. In addition, each hole such as the speaker hole 254, the switch hole 253H, the USB connector hole 252H, or the like is provided with a cylinder part or a seat part (hereinafter referred to as a cylinder part or the like). Further, a seat portion 226 is also provided at the upper part inside the case 22. The support column 221, the cylindrical 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 226 such as the support column 221 and the cylindrical portion comes into 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 inner peripheral side surfaces of the case 22 in the vertical and horizontal directions. Each of the ribs 222 and 223 is erected on the bottom surface so as to be connected to the inner peripheral side surface of the case 22. As will be described in detail later, the ribs 222 on the left and right sides are accommodated in slit holes 312 and 322 provided on the outer periphery 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 periphery 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, among the upper and lower ribs 223, the three ribs 223 in the upper left, upper right, and lower left (FIG. 18) have stepped end surfaces on the opening side, and the inner peripheral side is higher than the bottom surface. (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. About rib 223Z located in the lower right (FIG. 18), the cross-sectional shape is constant in the depth direction of case 22, and the shelf surface is not formed.

  In the following description, regarding the rib 223 in which the end face on the opening side is formed in steps and the protruding width at the tip is narrow, the root side portion is referred to as a rib main body portion 223B, and the portion with a narrow tip protruding width is referred to. It is referred to as a rib tip 223A.

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

  On the surface of the substrate 31 on the side where 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 disposed at each position corresponding to the operation button 24. Has been. In the assembled state, as described above, the cylinder portion of the through hole 29 of the front frame 21 abuts on the first substrate 31, and the operation portion 315 is located inside the cylinder portion (FIG. 21).

  The white LED 315B is an illumination unit that illuminates the operation area of the operation button 24 from the back side. The light of the white LED 315B is transmitted 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. Note that a multi-color LED may be employed instead of the white LED 315B. If a multi-color LED is employed, it is possible to perform control such as changing the color in addition to changing the brightness.

  In a gap 152S between the left and right liquid crystal displays 152L and R, a proximity sensor (detection sensor, electronic component) 125 (not shown) for detecting a human body such as a palm is disposed. The proximity sensor 125 is used to detect a hand-holding operation on the screen region 15A (FIG. 1) where the screens 15L and R are arranged. The proximity sensor 125 is illustrated in FIG. 28, but is not illustrated in FIG. In this example, the proximity sensor 125 is disposed in the gap 152S. However, instead of or in addition to this, an electronic component such as an LED can also be disposed. If a physical gap 152S is formed at the boundary between the two liquid crystal displays 152L and 152R, wiring for transmitting various signals may be arranged in the middle of the screen region 15A (FIG. 1) or electronic Parts can be arranged.

  Slit holes 312 and 313 for accommodating the ribs 222 and 223 (FIGS. 18 and 19) of the case 22 are formed on the outer periphery of the first substrate 31 (FIG. 20). The slit holes 312 and 313 are incomplete holes that open to the outer periphery of the substrate 31. The slit holes 313 provided on the upper and lower sides of the substrate 31 are provided at positions corresponding to the ribs 223 of the case 22 and are formed so as to accommodate the rib front end portions 223A located on the front end sides of the ribs 223 (see FIG. 22 and FIG. 23).

  The extending width of the slit hole 313 from the outer peripheral surface of the substrate 31 is set so narrow that the rib main body 223B cannot be accommodated. In the assembled state, the shelf surface between the rib tip portion 223 </ b> A and the rib main body portion 223 </ b> B comes into contact with the first substrate 31. In addition, since the notch part 319 is provided in the outer peripheral shape of the 1st board | substrate 31 in the position corresponding to the rib 223Z of the case 22, the accommodation structure of the rib 223 is not formed.

  The first substrate 31 is fixed to the front frame 21 with screws as shown in FIG. Notches 318 (FIG. 20) are provided at the four corners of the first substrate 31 fixed with screws. The notch 318 has a shape for avoiding interference with the screw support 213 and the seat 213A of the front frame 21.

(10) OBD Fuel Efficiency Information Screen The OBD fuel efficiency information screen in FIG. 39 is a display screen that displays instantaneous fuel efficiency and average fuel efficiency 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 vehicle information is not switched and displayed as in the OBD meter screen. On the OBD fuel consumption information screen, two types of fuel consumption are displayed in two upper and lower stages. In each stage, a numerical display of fuel consumption and a segment display of the degree of fuel consumption are arranged vertically. As combinations of two types of fuel consumption, there are 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.
In addition to the above, the standby screen includes a calendar screen for displaying the date and the like, and an OFF screen in which the screen 15 is completely dark (FIG. 29).

  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 a status icon on the left screen 15L. However, when the left screen 15L is a radar scope screen, an OBD meter screen, or an OFF screen, a status icon is displayed on the right screen 15R. When the left and right screens 15L and 15R are any one of the radar scope screen and the OBD meter screen, the status icon is not displayed.

  Further, as target icons displayed on the radar scope screen by the control unit 10, there are icons illustrated in FIG. Each target icon has a different display color depending on the degree of attention (the degree of necessity of notification), and the degree of attention increases in the order of green → blue → yellow → red. The distribution of the attention level is defined in advance according to the type (content) of the traffic monitoring activity related to the target.

  In some standby screens, the display color of characters can be selected from six colors prepared in advance. Further, standby setting is possible in which each standby screen is automatically switched and displayed at regular time intervals (for example, 1 minute).

■ 6. Warning screen ■
In the radar detector 1, a display pattern of a warning screen that the control unit 10 displays at the time of warning can be set. When the VIEW button 243 is pressed for a long time during display of the standby screen, the control unit 10 switches to display of a warning screen. As a display pattern of the warning screen, there are two screen warnings, one screen warning first, one screen warning second, and no warning screen pattern.

Further, the time is displayed in the lower right. The illustration 42 is displayed based on the illustration data stored in the database 100.

  There are the following three methods for displaying the display pattern of the two-screen warning. The first method is a method of displaying by long pressing the VIEW button 243. The second method is a method of selecting “radar scope” for the left screen 15L and setting “display switching distance → no switching” and “target information → notification panel” for the right screen 15R. Here, “” such as “display switching distance → no switching” indicates setting items in the radar detector 1. The third display method is a method of setting “radar scope” for the left screen 15L, and setting “display switching distance → setting distance” and “target information → notification panel” for the right screen 15R. In the case of this method, when the distance between the vehicle and the target reaches the distance set by the display switching distance, the display pattern is switched to the two-screen warning.

  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 another radar detector having only one screen, it is necessary to display target information such as a target type and a distance using a part of the radar scope screen. If it is a two-screen warning, target information can be displayed separately from the radar scope screen. With such display specifications, a wide display area on the scope surface can be secured 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) One screen warning 1
As shown in FIG. 43, the display pattern of the one-screen warning 1 includes a radar scope screen that displays the vehicle position and the target position, and a telop 41 that indicates the type and distance of the target at the top of the standby screen. It is a setting. In the radar detector 1 of this example, the display pattern of the one-screen warning 1 in which the clock screen is set as the standby screen is the initial setting.

  There are the following two methods for displaying the display pattern of the one-screen warning 1. The first method is a method of setting “radar scope” for the left screen 15L and setting “display switching distance → no switching” and “target information → telop” for the right screen 15R. The second method is a method of setting “radar scope” for the left screen 15L, and setting “display switching distance → setting distance” and “target information → telop” for the right screen 15R. In the case of this method, when the distance between the vehicle and the target reaches the distance set by the display switching distance, a warning screen as shown in FIG. 43 is switched and displayed. Note that whether the telop 41 is displayed on the left or right screen 15L or R can be selectively set by an operation on the user side.

(3) One 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 a standby screen and an alarm panel screen is displayed on the right screen 15R at the time 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. . Note that which of the left and right screens 15L and R displays the notification panel screen can be set by a setting item of “notification display”.

(4) No warning screen As shown in FIG. 45, the display pattern without the warning screen displays the standby screen on both the left and right screens 15L and R, and at the time of alarm, either the left or right screen 15 (the right screen in the figure). 15R) is a display pattern in which only the telop 41 is displayed. For the display pattern without a warning screen, a standby screen other than the radar scope screen is set for both the left and right screens 15L and R, and “display switching distance → no switching” and “target information → telop” are set 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 action
(1) Alarm action at the time of reception of control radio waves When the control section 10 receives a control radio wave such as a radar wave or a stealth wave, the control section 10 performs an alarm action 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 a standby screen. The control unit 10 executes a W alarm that warns with both sound (electronic sound / alarm voice) and 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 top of the radar scope screen. This telop 41 includes a display (for example, L5) of a reception level of radio waves such as radar waves.

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 no radar wave being received is received. Examples of the mute operation include a hand-holding operation in which the hand is held over the screen region 15A (FIG. 1) for a certain time (one second), a long-press 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 performs control to reduce the volume of the alarm sound.
Further, as shown in FIG. 47, the control unit 10 performs an electronic operation according to a change (L1 → L5) in the reception level (radio wave intensity) accompanying the approach to the radar wave transmission source in the alarm operation at the time of receiving the control radar wave. The control to increase the tempo of the sound is executed.

(2) Alarm action at the time of target approach The control unit 10 displays a telop 41 for displaying target information and distance as shown in FIG. 48 when the distance between the vehicle and the target becomes small (when approaching the target). It is displayed at the top of the screen 15.

  FIG. 6A shows an example when “telop display” is set for the clock screen set as the standby screen. FIG. 4B shows an example when << Telop display >> is set for the radar scope screen. In the case of the radar scope screen on the left screen 15L, the time is not displayed, but in the case of the radar scope screen on the right screen 15R, the time is displayed on the lower right. FIG. 3C shows a change in the background color of the screen 15 controlled by the control unit 10 in accordance with the alarm attention level. FIG. 4D shows an example when “Telop display” is set on the notification panel screen.

(3) Warning voice When the control unit 10 outputs a warning voice as a target for 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, Add the phrase “right direction” and execute control to announce the direction (direction of the implementation point). The “right” and “left” voices are the direction of the target at the time of notification. When the distance to the target is very close, a phrase for identifying the left-right direction may not be added. Here, “” means sound output by alarm voice.

The warning voice is output at each timing shown in FIGS. In FIG. 50, the warning voice regarding the orbis (speed violation control) is shown in the upper part, and the warning voice related to the control area is shown in the lower part.
For example, in the case of an Orbis warning voice, stages of 2 km ahead (only on the highway), 1 km ahead, 500 m ahead, immediately before, and 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, for example, a distance such as “2 km ahead” is output as a voice. Furthermore, in addition to the distance voice output at 1 km ahead, an alarm voice or the like that notifies the speed limit or overspeed is output, and an alarm voice that notifies the camera position is output after 500 m. If the speed has been exceeded immediately before, the control unit 10 executes control for outputting a warning voice for an overspeed notification in addition to the immediately preceding traveling speed notification.

  For example, in the case of a warning voice in a control area, each stage of 1 km ahead, area entry, and area exit is set, and a warning voice is output for each stage under the control of the control unit 10. In the stage 1 km ahead, the warning voice also outputs whether the area is in the left-right direction. During display of a display screen other than the radar scope screen, the control unit 10 displays an icon (see FIG. 40) corresponding to the control / inquiry area at the bottom of the display screen.

  Note that the sound output (speech) such as an alarm voice can be muted (muted) by a hand-holding operation on the screen area 15A (FIG. 1). When the proximity sensor 125 arranged in the gap 152S (FIG. 20) between the left and right liquid crystal displays 152L and R detects the human body and the duration of the detection state reaches 1 second, the control unit 10 outputs an audio output. Control so that it is not muted and output. If a threshold value of 1 second or the like is set for the duration of the detection state, for example, there is less risk of erroneously detecting the movement of the driver's hand who is trying to operate the audio or the like by moving his hand away from the steering wheel.

■ 8. Various settings ■
In the radar detector 1, a plurality of types of operation specifications are prepared, and a desired operation specification is set by a user operation. Hereinafter, the setting method will be described.
When the MUTE button 248 is pressed for a long time with the power on, the control unit 10 executes control to display a setting menu. The left diagram of FIG. 54 illustrates the items of the setting menu, and the right diagram illustrates 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 Each setting menu is available, and a menu for finishing the setting is also provided. The control unit 10 changes the currently selected menu according to the operation of the ▲ button 242 and the ▼ button 244, and executes control to display a setting screen corresponding to the selected menu when the MUTE button 248 is operated. . The right figure shows 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). Have been).

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

(2) Mode setting The radar detector 1 is provided with a manual mode in addition to the four preset alarm modes (normal, minimum, special, all-on). You can set your preferred alarm mode by user operation. The normal mode is an alarm mode with setting contents 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 setting contents that emphasize items related to control. 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 for a long time while the standby screen (upper left diagram) is displayed as shown in FIG. 56, the control unit 10 switches to the setting screen (upper right diagram). When << Mode >> in the setting menu is selected, the control unit 10 switches to the display of the mode screen (lower left figure). When the end of setting is selected after the preferred alarm mode is selected (the lower right diagram), the control unit 10 executes 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, each item of the reception sensitivity mode, road selection, display switching distance, target information, and notification display can be set.
In the reception sensitivity mode, “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, a GPS warning target road can be selected from << general road >> << highway >> << ALL >> << AUTOGPS priority >> << AUTO atmospheric pressure priority >>. In the “General road” setting, only the target of the general road is warned. In the “Expressway” setting, only the target of the expressway is warned. With the setting of “ALL”, all the targets of general roads and highways are warned. The setting of “AUTOGPS priority” is a setting in which the position information of GPS is preferentially used, and the control unit 10 automatically identifies the type of the traveling road (general road or highway). The setting of “AUTO atmospheric pressure priority” is a setting in which a change in atmospheric pressure is preferentially used, and the control unit 10 automatically identifies the type of traveling road (general road or highway). The control unit 10 performs control to alert only the target of the general road when it can be identified as a general road, and to alert only the target of the highway when it can be identified as a highway. Other setting items are as shown in FIG.

  As the display switching distance, any one of “no switching”, “500 m”, “1000 m”, and “1500 m” can be selectively set. If the display switching distance is set, as explained in “6. Warning screen”, when the distance from the vehicle to the target is near, the display is switched 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, “Display switching distance → 1000 m” and “Target information → Notification panel” are set for the right screen 15R, the control is performed. The unit 10 executes 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. Note that 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, items 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 to any one of “minimum”, “dark”, “normal”, and “bright”. For the LED mode, one of << Alarm / Touch ON >><< Always ON >><< 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 content of the white LED 315B for each of the operation states 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 state 1, each white LED 315B is normally controlled to be turned off (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 in a lighting state. The touch operation on the screen 15 is detected by the touch area 151S of the touch screen sheet 151. The hand-holding operation on the screen area 15A (FIG. 1) is detected by the proximity sensor 125 (FIG. 28) disposed 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 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. The controller 10 determines that there is an operation. As the predetermined duration, 1 second is set as described above for the mute hand-hold operation. For the hand-holding operation in the standby state, it is preferable to set a time shorter than 1 second, for example. Regarding mute hand-holding operation, it is necessary to avoid the possibility of false detection of a hand operating the car audio, etc., and to mute the alarm voice, etc., while hand-holding operation in the standby state is slow. This is because it is necessary to prioritize the operation response so that a good impression does not occur.

  When any one of the operation buttons 24 is touched after the hand-holding operation or the like is performed under the standby state (state 1) as described above, the control unit 10 turns on the white LED 315B only for the operated operation button 24. Control is performed to turn off the light and return to the lighted state when the touch operation ends. Thereafter, when the non-operation period in which none of the operation buttons 24 is operated exceeds a predetermined time, the control unit 10 performs control to switch all the white LEDs 315B to the off state. Instead of this example, when the touch operation is finished, the operation button 24 may be blinked for a predetermined time. It becomes easier for the user to know that the operation has been accepted.

In the state 2 corresponding to the alarm, the control unit 10 performs control to blink all the white LEDs 315B. In addition, when there is a direction of the left side, the right side, or the front of the position (implementation point) of the traffic monitoring activity to be alarmed, for example, only the white LED 315B on the left side blinks, or only the white LEDs 315B on the top two places It is also effective to execute a control of blinking.
Note that during alarming, for example, it is also possible to execute control of blinking all white LEDs 315B in accordance with the degree of attention (degree of necessity of notification) of the alarm target. For the operation buttons 24 arranged at five locations on the outer periphery of the screen area 15A, the control may be performed such that the lighting position circulates around the screen area 15A during an alarm by slightly changing the lighting timing. good. In addition, as the degree of attention increases, the circulatory cycle may be accelerated to produce a sense of urgency. Alternatively, when entering a traffic accident-prone area or the like, it is also possible to sensuously express a high-risk situation by randomly lighting the five operation buttons 24.

  In the state 3 corresponding to when the power is turned on in response to the vehicle ignition being switched on, the control unit 10 performs control to blink all the white LEDs 315B, and then performs control to turn off all the lights when a predetermined time has elapsed. Note that the blinking of the white LED 315B is realized not by complete on / off periodic switching but by control of periodically changing the brightness. According to the control for periodically changing the brightness, it is possible to perform blinking of light like fireflies (the blinking cycle should be faster than that of fireflies), and it is possible to produce a high-class feeling of the apparatus.

  In the “always on” LED mode, the control unit 10 performs 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 on (state 3), Control to blink the white LED 315B is executed.

  When the LED mode is << OFF >>, the control unit 10 performs control (flashing control) of 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) Audio setting The audio setting is a setting relating to an output mode (output mode) of various sound information such as sound such as an alarm voice and sound effects. In the voice setting, as shown in FIG. 61, it is possible to set items such as speaking speed (speaking speed), narrator switching, radar warning sound, positioning announcement, RELAX chime, time signal, operation sound, target approach sound, and the like. The speaking speed can be switched in four stages: “slow”, “normal”, “fast”, and “alarm interlock”. In particular, in <Alarm Link>, the speech speed is changed depending on the type of alarm. In narrator switching, the warning voice can be switched between << Women >><< Men >>. Radar warning sound can be switched between “Voice” and “Electronic sound”.

  In the positioning announcement, on / off of the positioning announcement can be selected. For example, if the reception status of GPS radio waves is not good, such as in a valley of a building, positioning announcements may be repeated as “GPS cannot be received” or “GPS has been received”, but if the positioning announcement is turned off, such repetition is repeated. Can be avoided. The RELAX chime is a function that prompts you to take a break at regular intervals. It is possible to select a time interval for voice output. The time signal is a function for notifying the time every hour and at noon, and the presence or absence of the time signal can be selected. The operation sound can be set as to whether or not a confirmation sound is generated when the button is operated. The target approach sound is an output sound when the target approaches, and the target approach sound is output according to the ON setting.

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

  Note that 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, audio data obtained by digitally recording an actual utterance by a narrator is recorded in the database 100. The voice data in the database 100 is record data corresponding to a speech speed of 120%. When the audio data is reproduced as it is, the speech speed becomes 120%. When the audio data is reproduced approximately 20% later, the speech speed is 100%, and when the audio data is reproduced later, the speech speed is 90%.

  In the radar detector 1 of this example, the audio data corresponding to 120% speech speed is recorded in the database 100, thereby reducing the data size of the audio data stored in the database 100. Naturally, voice data corresponding to 100% of the speech speed may be recorded in the database 100, and voice data exceeding the speech speed that is actually output, such as 130% of the speech speed, may be recorded in the database 100.

  When << alarm interlock >> is set, the control unit 10 changes the speech speed according to the type and situation of the traffic monitoring activity to be alarmed as shown in FIG. In the figure, the stealth notification and the RD notification are (1) alarm operation at the time of reception of the control radio wave described 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 approaching the target in “7. Alarm operations”. In the figure, “All sound effects” (fourth line from the bottom) in the notification content column is, for example, “(Sound effect) stealth received stealth received” in the phrase example column. (For example, “poon”). For example, in the case of stealth notification, the control unit 10 outputs a phrase “stealth reception stealth reception” at a speech speed of 120% following the output of a sound effect of 100% speed.

  For example, in the case of RD notification, the control unit 10 outputs a phrase such as “Please be careful about speed” following the output of the sound effect of 100% speed. At this time, the control unit 10 changes the speaking speed of a phrase such as “Be careful with 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 degree of attention is not so high, the control unit 10 outputs a sound effect with a speed of 100%, followed by the phrase “Beware of speed control”. Is output at 90% speech speed. In the case of the reception level 3, the control unit 10 outputs the phrase “Please pay attention to the speed” at 100% speech speed following the output of the sound effect at 100% speed. When the reception level is 4 or 5, since the degree of caution is high, the control unit 10 says “Be careful about driving” or “Let's reduce the speed” following the output of 100% sound effects. The phrase is output at 120% speech speed. The control unit 10 outputs an alarm voice each time the reception level changes such as reception level 2 → 3.

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

  The control unit 10 controls the speed of the sound effect to be constant at 100% regardless of the speaking speed of the subsequent phrase. In this way, if the output form of the sound effect that triggers the alarm action is set to exactly the same specification regardless of the speaking speed of the phrase, the sound effect that means the start of the alarm action can be strongly impressed on the user side, This has the effect of suppressing the risk of being missed.

  As described above, by changing the speaking speed of the phrase, the user's impression of the utterance can be made different. For example, if a fast speech speed is set, an impression that attention is high can be given by producing a sense of urgency. In this example, the attention level is defined by the type of traffic monitoring activity to be alarmed, and the display color of the target icon corresponding to the attention level is set (FIG. 41). It is also possible to change the speaking speed according to the display color of the target icon. For example, for traffic monitoring activities where the attention level is low and the display color of the target icon is green, it is possible to apply a control that always sets a slow speaking speed and does not change the speaking speed.

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 the presence or absence of excessive speed. The shorter the distance, the faster the speaking speed of the phrase following the sound effect, and the faster the speaking speed of the phrase when the speed is exceeded than when the speed is not exceeded.
For example, in the case of an inspection / control notification, the control unit 10 changes the speaking speed of the phrase depending on whether the vehicle speed is 52 km / h or more. When the vehicle speed is 52 km / h or higher, the speech speed is made faster than when the vehicle speed is less than 52 km / h.

  With respect to the target approach sound for sound setting (distance-linked orbit sonar sound shown in FIG. 63), << ON >> << OFF >> can be selectively set. When the target approaching sound is set to “ON”, the control unit 10 outputs a sonar sound when approaching Orvis as shown in FIG. After the distance to Orbis becomes 1 km or 2 km and the Orbis notification is executed, the control unit 10 outputs an Orbis sonar sound at a transmission period 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 Orbis reaches 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 period of the orbit sonar sound according to the distance and increases it to 2.5 Hz when it reaches 200 m, and then ends the output of the orbit sonar sound according to the passage of the orvis. . Thus, if the transmission cycle of the orbit sonar sound is changed in conjunction with the distance to the orbis, the degree of caution can be grasped only by the orbis sonar sound. Even if the user misses the distance due to the Orbis announcement, the degree of distance can be grasped by the Orbis sonar sound.

(6) System Settings In the system settings, various system settings can be made as shown in FIG.
(7) OBD setting In the OBD setting, as shown in FIG. 65, it is possible to set each item of OBD meter, fuel consumption information, coefficient correction, and data deletion for each screen 15. When the OBD meter is set, 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 air temperature, engine oil temperature, instantaneous fuel consumption, Either average fuel consumption or current fuel consumption can be set selectively. 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 15R. 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. Has improved. As described above, when the plurality of screens 15L and R are used, the monitoring information can be easily notified.

  Further, the radar detector 1 can control the operation area of the operation button 24 to blink. If the operation button 24 is blinked, it is possible to attract the user's attention effectively by causing a movement of brightness change. If the user's attention can be attracted, it is possible to suppress the possibility that the monitoring information to be notified is missed without being recognized by the user.

The radar detector 1 changes the output mode of sound information such as an alarm voice according to the degree of attention (degree of necessity of notification) of the monitoring information to be notified. If the output mode of the sound information is changed 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 speech speed is changed, information indicating a difference in attention can be notified. Further, if the sound information output mode is different, it can be intuitively recognized from the user side.
As described above, the radar detector 1 of this example has excellent characteristics that can easily and easily notify monitoring information related to traffic monitoring activities.

  In the radar detector 1, a housing structure is realized in which ribs are housed in slit holes provided on the outer periphery of the substrate. In this housing 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 is possible to expect improvement in rigidity (particularly torsional rigidity) of the housing (case body 2) by using the strength of the substrate. 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 substrate-side through hole that accommodates such a rib may be a closed hole that does not open to the outer periphery.

  In the radar detector 1 of this example, the screens 15L and R are arranged in parallel on the same plane. Instead of this configuration, the positions of the screens 15L and R in the thickness direction (depth direction) of the case body 2 may be changed. For example, the screen 15R may be disposed on the back side with respect to the screen 15L. Further, the screen 15L and the screen 15R may be arranged so as to overlap in the depth direction, and the front screen 15 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.

  Furthermore, the screens may be arranged 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, the image information visible from the user side can be switched according to the direction of the dice-shaped housing.

  The front surface of the case body 2 may be formed so that the center in the left-right direction is raised and positioned on the front side in the depth direction, and an inclined surface is positioned on the back side in the depth direction toward the left and right sides. If screens are installed on the inclined surfaces formed on both sides across 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 side and the other Will face the passenger side of the passenger seat, making it possible to achieve both driver and passenger visibility. In this case, the same display screen may be displayed on each screen. In addition, when the screen orientations (normal directions) 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. Get higher.

  In the radar detector 1 of this example, the operation buttons 24 by the operation unit 315 including the white LEDs 315B are arranged on both the left and right sides of the screen area 15A where the screens 15L and R are arranged. For example, the direction of the target may be indicated according to which operation button 24 is lit or blinked. For example, if the target is left with respect to the traveling direction of the vehicle, the left operation buttons 241 and 243 may be blinked. If the target is a front target, the upper and left operation buttons 241 and 242 may be blinked. . If the direction is indicated by blinking of the operation button 24 or the like, it is possible to realize easy-to-understand notification that allows the user to 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. If five operation buttons 24 on the outer periphery of the screen area are used, for example, it is possible to perform control such that the lit operation button 24 circulates around the screen area 15A. For example, when an alarm regarding a traffic monitoring activity is executed, the cycle of rotating the lighting position may be changed according to the degree of caution, and the cycle may be increased as the degree of caution increases. 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 a simple setting, a radar scope screen is displayed on the left screen 15L, a clock screen as a standby screen is displayed on the right screen 15R, and when the distance to the target reaches a predetermined distance, an upper portion of the clock screen is displayed. A 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 simple setting mode that can selectively set 2 to 3 types of standby screens is added. It is also good to do. Although the simple settings in this example are not satisfactory, it is possible to meet the user needs such that the mode in which all settings are possible is 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 a proximity sensor for detecting a hand-holding operation or the like. I have. A capacitive touch sensor may be employed for each operation button 24, and a hand-holding operation may be detected using these touch sensors. In this case, it is preferable to change the detection distance of the touch sensor between a state of waiting for a hand-holding operation and a state of waiting for a touch operation. For example, in a state where the hand-holding operation is on standby, the detection distance is set to be long. On the other hand, after the hand-holding operation is detected, the touch operation on each operation button 24 can be detected with high reliability by making the detection distance close to zero.

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

The radar detector 1 of this example may include a map display function. It is also possible to display a map on which one of the target icons is plotted on one screen and display a telop that displays information about the target icon on the other screen. Further, for example, it is also possible to display maps with different scales 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 accurately grasping the distance to the target. Furthermore, for example, it is also possible to display a target icon for which an implementation point is specified on a map on one screen and display a target with an area specified on a map on another screen. In general, it is necessary to display the pinpoint for the target where the execution point is specified, so plotting on a narrow area map is suitable, while for the target for which the area is specified, the entire area is indicated. Wide range map display is suitable because it is necessary.
