Description

The present invention relates to a device that supports vehicle driving by providing information regarding various traffic monitoring activities such as traffic enforcement and inspections.

2. Description of the Related Art Conventionally, devices such as radar detectors have been realized as devices for supporting vehicle driving, which issue an alarm when receiving radar waves for speed enforcement and call the driver's attention. Some of these devices have a GPS function that measures the current location of the vehicle and a database of GPS targets such as installation points for speed enforcement systems, and detect when approaching a specific GPS target and drive the vehicle. There are also methods to notify the user (for example, see Patent Document 1). According to such a device, it is possible to prevent the driver from unknowingly speeding too much by notifying the driver of the approach to the point where the traffic monitoring activity is to be carried out.

GPS targets whose approach is notified by the device configured as above include speed control system installation points and permanent points such as police stations, as well as locations where traffic monitoring activities such as speed control and alcohol checks by mobile orbis are frequently carried out. There are temporary points etc. that will be implemented. The device aims to raise drivers' awareness of safe driving by notifying them of their approach to various GPS targets.

In particular, vehicle speed measuring devices and the like used for speed enforcement are often installed at dangerous points where excessive speeding is likely to be induced. The approach notification to such a point is very effective in heightening the driver's awareness of safe driving before a danger occurs, and in order to prevent the danger from occurring. Devices such as radar detectors are extremely useful for motivating drivers to drive safely, and have become devices that contribute to ensuring traffic safety and support driving.

However, the conventional device described above has the following problems. In other words, while there are users who want to be presented with a lot of information, such as the type of traffic monitoring activity to be alerted, the location of the activity, and the distance to the activity point, they find it difficult to understand the alert due to the amount of information presented. There are also quite a few users.

The present invention has been made in view of the above-mentioned conventional problems, and is an invention for providing a device that can notify monitoring information regarding traffic monitoring activities in an easy-to-understand manner.

The present invention is a device for notifying monitoring information regarding traffic monitoring activities, comprising:
Equipped with two displays with screens that can display monitoring information,
There is a device in which the screens of the two displays are arranged horizontally in parallel.

In the device of the present invention, two screens capable of displaying monitoring information are arranged side by side in parallel. If there are two screens, monitoring information etc. can be displayed more clearly than when there is only one screen. For example, if you use one screen to display monitoring information as an image and the other screen to display the monitoring information in text, you will be able to accurately understand the monitoring information by viewing both side-by-side screens. .
As described above, the device of the present invention is a device that can notify monitoring information related to traffic monitoring activities in an easy-to-understand manner.

By arranging two displays horizontally as in the device of the present invention, it is possible to realize a smart product form that is long in the horizontal direction and low in height, wide and low.
2. Description of the Related Art Conventionally, a horizontally long single-screen device has become common as a device for notifying monitoring information. A variety of software has been developed for such devices to display various types of information on a horizontally long screen. If there are two screens arranged side by side in the horizontal direction, there is a high possibility that the conventional screen specifications for horizontally long screens can be used as is. If conventional screen specifications can be used, software development costs can be reduced and attractive product costs can be realized.

The device of the present invention may be used for in-vehicle applications, for example, or may be used for uses other than in-vehicle applications.
In a device according to a preferred aspect of the present invention, a gap is provided between the two displays arranged in parallel in the horizontal direction.
In the case of a device having only one display, even if the screen size can be secured by increasing the screen size, it is physically impossible to provide a gap in the middle of the screen. The horizontal gap is only achieved by employing two indicators. The horizontal gap is effective, for example, for distinguishing information displayed on each screen, and it becomes possible to present information that is easy to understand from the user's perspective.

In a preferred embodiment of the device of the present invention, an electronic component is disposed in the gap.
In the case of a single screen, it is impossible to place electronic components in the middle of the screen, but if two displays are provided, they can be placed in the middle of the screen area made up of the two screens. Electronic components can be placed. The restriction that electronic components must be placed on the outer circumferential side while avoiding the screen area is eliminated, and the degree of freedom in placing electronic components is increased.

In a preferred embodiment of the device of the present invention, the electronic component is a detection sensor for detecting a nearby human body.
According to the detection sensor disposed in the gap, it is possible to detect an operation such as placing a hand over a screen area made up of two screens. Generally, when performing an operation in which the user places their hand over the screen, many users try to place their hand over the center of the screen. Since the gap is located midway between the screen areas made up of the two screens, it is suitable as a placement location for a detection sensor that detects a hand-holding operation. Note that a light emitting element such as an LED may also be arranged as the electronic component. In this case, the light emission can produce an effect similar to a partition separating two screens.

A device according to a preferred embodiment of the present invention includes an electronic board on which two displays are mounted and a through hole penetrating in the thickness direction;
a casing having a rib extending through the through-hole of the electronic board, and accommodating the electronic board with the rib extending through the through-hole;
A contact structure is formed between the inner circumferential surface of the through hole and the outer circumferential surface of the rib, and the rigidity of the casing is increased by utilizing the strength of the electronic board.

An electronic board on which two displays are mounted tends to have a larger size in the direction in which the two displays are arranged. The width of the casing that accommodates this electronic board in its arrangement direction also increases. When two displays are arranged horizontally, the width of the housing in the horizontal direction becomes large, and it becomes necessary to ensure the torsional rigidity of the housing. By providing the above-mentioned ribs on the casing and forming a contact structure with the electronic board, the rigidity of the casing can be ensured by utilizing the strength of the electronic board. In this case, the rigidity that should be ensured by the casing itself can be suppressed, so it is possible to avoid increasing the cost and size due to thickening necessary to ensure rigidity and providing a shape to ensure rigidity.

The through hole provided in the device according to a preferred aspect of the present invention is an incomplete hole that communicates with the outer circumferential side of the electronic board and opens in a part of the circumferential direction, and the rib is an incomplete hole that is open in a part of the circumferential direction of the electronic board, and It is erected in
If the ribs are erected on the inner circumferential side of the housing, it is easy to ensure that the ribs are supported with high rigidity by the housing. By using ribs that are highly rigidly supported by the casing, the strength of the electronic board can be directly reflected in the rigidity of the casing. Further, generally, ribs provided upright on the inner circumferential side of the housing are also effective for improving the rigidity of the housing alone.

In a preferred aspect of the present invention, the contact structure is provided on both sides of the boundary between the two displays in the horizontal direction.
Providing the contact structure on both sides in the horizontal direction with respect to the boundary between the two displays allows the housing to be supported from both sides in the horizontal direction, which is very effective for ensuring the rigidity of the housing.

In a preferred aspect of the present invention, the contact structure is provided on both sides of the electronic board in the vertical direction.
In this case, the casing can be supported from both sides in the vertical direction relative to the electronic board, which is very effective for ensuring the rigidity of the casing.

A device according to a preferred embodiment of the present invention includes a wireless module including a receiving antenna and a detection circuit for receiving radio waves emitted by traffic monitoring activities,
The wireless module is arranged so as to overlap the boundary between the two displays in the normal direction of the screen.

Generally, wireless modules need to be surrounded by a metal casing or the like to prevent noise, and thus tend to be heavy. By arranging the wireless module so as to overlap the boundary between two horizontally parallel displays, it is possible to bring the center of gravity of the device close to the horizontal center and achieve good weight balance. By achieving a good weight balance, it is possible to achieve stable in-vehicle mounting, and it is possible to improve visibility by suppressing screen shaking caused by vibrations from the vehicle.

In the device according to a preferred aspect of the present invention, on the front side where the screens of the two displays are arranged in parallel, a touch screen sheet for detecting a user's touch operation is laminated so as to cross the two screens. has been done.
If the touch screen sheets are stacked across two screens arranged in parallel in the horizontal direction, the number of parts can be reduced compared to the case where touch screen sheets are arranged for each screen.
Furthermore, for example, by using touch screen sheets stacked across two screens, seamless touch operations can be achieved in the screen area that includes the two screens. In this case, even though there are two screens, touch operations similar to those for a single screen area can be performed, and the operational feeling can be improved.

In a preferred embodiment of the device of the present invention, the front side is provided with a positioning shape that matches a part of the sheet shape of the touch screen sheet.
A touch screen sheet that crosses two screens arranged in parallel in the horizontal direction tends to have a long horizontal width, making positioning difficult. By providing a positioning shape on the front side, it is possible to suppress the difficulty level when stacking touch screen sheets.

In a preferred aspect of the present invention, the positioning shape is provided corresponding to a horizontally intermediate position of the touch screen sheet.
In this case, for example, there is no need to start pasting the touch screen sheet from the horizontal (left and right) ends. If there is a misalignment in the angle of the touch screen sheet when you try to paste it from either horizontal edge, the misalignment will be amplified as you move toward the opposite horizontal edge, and the pasting will be completed. There is a risk that a very large discrepancy will occur. On the other hand, if the positioning shape is provided at the position described above, it becomes possible to start pasting from an intermediate position in the horizontal direction of the touch screen sheet and continue pasting on both sides in the horizontal direction. If the touch screen sheet is to be pasted on both sides in the horizontal direction from an intermediate position, the distance from the beginning of pasting to the end of pasting is shortened, so that the deviation that occurs at the ends in the horizontal direction is reduced.

A device according to a preferred aspect of the present invention includes an electronic component that executes calculation processing for controlling the screens of the two display devices,
The electronic components are shared between the two displays.
If the electronic components can be shared between the two displays, it is possible to suppress the expansion of the scale of the hardware configuration for controlling the screen of the display even when two displays are provided.

Embodiments of the present invention will be specifically described using the following examples.
(Example 1)
This example is an example of a radar detector (device) 1, which is one aspect of the system, and whose main function is to issue warnings regarding traffic enforcement. This radar detector 1 is a device suitable for use in a vehicle. This radar detector 1 reports various information useful when driving a vehicle, including monitoring information regarding traffic monitoring activities such as speed enforcement. The contents will be explained in the following order with reference to FIGS. 1 to 65.

1. Shape 2. Structure 3. Electrical configuration 4. Basic movements 5. Standby screen 6. Warning screen 7. Alarm action 8. various settings

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

A screen area 15A (FIG. 1) is formed on the front surface (front surface) of the radar detector 1, in which two 1.8-inch color screens 15L and 15R are arranged side by side in the left-right direction (horizontal direction). Above and below the border between the left and right screens 15L and 15R, a label area 210 on which the model number and model name of the radar detector 1 are printed is provided so as to dig 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. Volume adjustment buttons ▲ button 242, ▼ button 244, and MUTE button 248 are arranged on the right outer side of the screen 15R on the right side when viewed from the driver's side. 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 at the lower rear of the case body 2. A cigarette plug cord extending from a vehicle's cigarette lighter socket, an OBD adapter (FIG. 13), a USB cable, and the like are connected to the USB connector 252. The radar detector 1 operates by receiving power supply through a cord connected to the USB connector 252.

The OBD adapter shown in Figure 13 is installed on the vehicle side in accordance with the OBD (On-board Diagnostics)-II (II is the Roman numeral "2", hereinafter referred to as "OBD") standard, which is a vehicle inspection standard. This 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 is capable of outputting various vehicle information. A connector is attached to the vehicle-side end of the OBD adapter to be detachably attached to the vehicle's OBD connector.

■ 2. Structure (1) As shown in FIG. 14, the radar detector 1 is constructed by pasting a touch screen sheet 151 on the front side of the case body 2 that houses the first and second boards 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 in FIGS. 14 and 15 is a horizontally long sheet disposed close to the entire width of the case body 2 in the left and right direction. A constriction shape 151D that protrudes downward or upward from the outer circumferential side toward the inner circumferential side is provided in the middle portion of the touch screen sheet 151 (FIG. 15) in the left-right direction, forming a narrow part with a narrow width in the vertical direction. has been done. The touch screen sheet 151 provided with this narrow portion has a shape similar to glasses as a whole.

In the touch screen sheet 151, touch areas (sensing areas) 151S are formed in two vertical columns on the left and right sides of the screens 15L and 15R, respectively. Note that instead of the configuration of this example, a touch area may also be provided between the two rows of left and right touch areas 151S. By providing three rows of touch areas on the screen 15 in this way, it becomes possible to detect, for example, a touch operation in which the touch position moves from the right touch area to the center and then to the left, so that a so-called flick operation can be detected. It becomes possible.

At both ends of the touch screen sheet 151, watermarks 151V such as letters such as MEMO and triangular shapes (▲ and ▼) are provided at positions corresponding to each operation button 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 from the white LED (illumination means) 137 housed inside.

The front frame 21 in FIGS. 16 and 17 has a shape similar to a frame body provided with an opening 218. The opening 218 is an opening for arranging two liquid crystal displays (displays) 152L and 152R mounted on the first substrate 31. Through holes 29 are bored in the frame portion of the front frame 21 at positions corresponding to the respective operation buttons 24. Note that the through hole 29 on the left side as viewed from the front side is missing one side surface in the circumferential direction, and is an incomplete hole communicating with the opening 218.

A shallow recessed portion 210A that matches the sheet shape of the touch panel 151 is formed on the outer surface facing the front side. The bottom surface of this shallow recessed portion 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 recessed portion 210A along the surfaces of the liquid crystal displays 152L and 152R.

A label area 210 is formed on the upper and lower sides of the front surface of the front frame 21 and projects from the outer circumferential side toward the opening 218 side. 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 by being raised higher by the thickness of the touch screen sheet 151 with respect to the bottom surface of the recessed portion 210A. In addition, when the touch screen sheet 151 is attached to the front frame 21 in an assembled state, the combination of the label area 210 protruding from the top and bottom 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 serves as a positioning shape when attaching the touch screen sheet 151. In the radar detector 1 of this example, since the positioning shape is located in the middle part of the case body 2 in the left-right direction, there is no need to start pasting the touch screen sheet 151 from either the left or right end side. For example, it is possible to start pasting from either the top or bottom.

If there is a misalignment in the angle of the touch screen sheet 151 when you try to start pasting the touch screen sheet 151 from either the left or right edge, the misalignment will be amplified as you move toward the opposite end, and the pasting will not be completed. A very large deviation may occur. On the other hand, when the positioning shape is provided in the middle part in the left-right direction, it is also possible to start pasting from around the middle in the left-right direction of the touch screen sheet 151 and continue pasting on both sides in the left-right direction, for example.

If the touch screen sheet 151 is started 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. Furthermore, it is also possible to start pasting the touch screen sheet 151 in the vertical direction from either the top or bottom side, for example. Since the width of the touch screen sheet 151 in the vertical direction is narrow, for example, even if some angular deviation occurs when pasting starts from the upper side, there is little possibility that a large deviation will occur on the lower side.

On the back side of the front frame 21 (see FIG. 17), screw supports 213 are erected at the four corners, and two screw holes 211 are bored at the top and bottom. A seat portion that comes into contact with the first substrate 31 is formed on the outer periphery of the screw hole 211 . A cylindrical portion extends into the through hole 29 corresponding to each operation button 24, and the end surface thereof is flush with the seat of the screw hole 211 so that it can come into contact with the first board 31. ing.

A seat portion 213A that extends linearly in the radial direction is provided on the outer peripheral side of the screw column 213. The seat portion 213A is formed at a circumferential position corresponding to the outer circumferential side of the front frame 21 in the vertical direction, and at a circumferential position corresponding to the outer circumferential side of the front frame 21 in the horizontal direction. For example, the lower right screw column 213 (see FIG. 17) when looking at the front frame 21 from the back side is provided with a seat portion 213A extending downward and a seat portion 213A extending rightward. This seat portion 213A is formed to have a lower height than the screw support column 213, and this difference in height approximately matches 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 case 22 shown in FIG. 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 having through holes are provided.

The end surface of the support column 221 forms a seat that comes into contact with 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 cylindrical portion or a seat portion (hereinafter referred to as a cylindrical portion, etc.). Furthermore, a seat portion 226 is also provided on the inside upper part of the case 22. The support 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 support 221, the cylindrical portion, etc., and the seat portion 226 come 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 upper, lower, left and right inner circumferential surfaces of the case 22, respectively. Each of the ribs 222 and 223 is erected on the bottom surface of the case 22 so as to be connected to the inner peripheral side surface thereof. As will be described in detail later, the ribs 222 on both 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 at the upper left, upper right, and lower left (FIG. 18) have the end surfaces on the opening side formed in a stepped manner, and the inner peripheral side has a higher height from the bottom surface. (See Figure 19.) The lower end surface forming the shelf surface is a contact surface against the first substrate 31 in the assembled state. Regarding the rib 223Z located at the lower right (FIG. 18), the cross-sectional shape is constant in the depth direction of the case 22, and no shelf surface is formed.

In the following explanation, regarding the rib 223 whose end face on the opening side is formed in different steps and whose protruding width at the tip is narrow, the part on the root side will be referred to as the rib main body part 223B, and the part with the narrow protruding width at the tip will be referred to as the rib body part 223B. This is called a rib tip portion 223A.

The first board 31 in FIG. 20 is a double-sided mounting board. On the mounting surface of the first substrate 31 on the front frame 21 side (front side) (see FIG. 20), liquid crystal displays 152L and 152R are mounted. A memory card reader 17 (see FIG. 24) is mounted on the mounting surface facing the second substrate 32 on the back side. Two notches 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 152R are connected to the notches 319, respectively. installed facing the

On the surface of the substrate 31 on which the liquid crystal displays 152L and 152R are mounted, operation units 315 including a capacitive touch sensor 315A and a white LED 315B (FIG. 28) are arranged at positions corresponding to the operation buttons 24. has been done. In the assembled state, the cylindrical portion of the through hole 29 of the front frame 21 contacts the first substrate 31 as described above, and the operating portion 315 is located inside this cylindrical portion (FIG. 21).

The white LED 315B is a lighting device that illuminates the operation area of the operation button 24 from the back side. The light from the white LED 315B passes through the watermark 151V (see FIG. 15) on 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 multicolor LED can also be used instead of the white LED 315B. If multi-color LEDs are used, it becomes possible to control things 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 152R, a proximity sensor (detection sensor, electronic component) 125 (not shown) that detects a human body, such as a hand, is disposed. This proximity sensor 125 is used to detect a hand-holding operation on the screen area 15A (FIG. 1) where the screens 15L and 15R are arranged. Note that the proximity sensor 125 is shown in FIG. 28, but is not shown in FIG. 20. In this example, the proximity sensor 125 is placed in the gap 152S, but instead of or in addition to this, an electronic component such as an LED may be placed. If a physical gap 152S is formed at the boundary between the two liquid crystal displays 152L and 152R, wiring for transmitting various signals or electronic It becomes possible to place parts.

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 on the outer periphery of the substrate 31. The slit holes 313 provided above and below the substrate 31 are provided at positions corresponding to the ribs 223 of the case 22, and are formed to accommodate the rib tips 223A located on the tip side of each rib 223 (see FIG. 22 and FIG. 23).

The width of the slit hole 313 extending from the outer circumferential surface of the substrate 31 is set to be narrow enough to not accommodate the rib main body portion 223B. In the assembled state, the shelf surface between the rib tip portion 223A and the rib main body portion 223B comes into contact with the first substrate 31. Note that, in the outer circumferential shape of the first substrate 31, a notch portion 319 is provided at a position corresponding to the rib 223Z of the case 22, so that a housing structure for the rib 223 is not formed.

The first board 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. This notch 318 is shaped to avoid interference with the screw support 213 of the front frame 21 and the seat 213A. The first substrate 31 having the notch 318 is in contact with the seat of the screw hole 211 (FIG. 17) and the end surface of the cylindrical portion extending from the through hole 29 (FIG. 17) corresponding to each operation button 24. They are screwed together in contact.

Note that since the first board 31 is screwed to the front frame 21, it is impossible to remove only the front frame 21, leaving the first board 31 behind. 22 and 23 are virtual diagrams showing a state in which only the front frame 21 is removed, leaving the first board 31, in order to explain the housing structure of the board 31.

The second board 32 (FIG. 25) on the rear side is a board on which a one-chip microcomputer (not shown), a USB connector 328, a speaker 16, an RF module (wireless module) 321, a GPS module 325, a power switch 253, etc. are mounted. be. Each electronic component other than the 1-chip microcomputer is mounted on the mounting surface shown in FIG. 25, and the 1-chip microcomputer (not shown) is mounted on the mounting surface on the back side. The second board 32 is electrically connected to the first board 31 via a control cable (not shown). The control cables between the first board 31 and the second board 32 include two cables connected to the connector 319C (FIG. 20) of the first board 31 extending from the liquid crystal displays 152L and 152R. There is a control cable.

A 1-chip microcomputer is an electronic component that includes a CPU, ROM, RAM, etc. on one chip. In particular, the one-chip microcomputer of this example has a control function for the liquid crystal displays 152L and 152R, and is an electronic component shared between the liquid crystal displays 152L and 152R. The mounting position of the one-chip microcomputer on the second board 32 is inside the area where the arrangement area of the liquid crystal displays 152L, R of the first board 31 is projected onto the second board 32 in the thickness direction of the case body 2. It becomes. Bus lines for transferring display data and the like to each of the liquid crystal displays 152L and 152R are laid on both the left and right sides of the one-chip microcomputer. It is also possible to arrange a one-chip microcomputer at an intermediate position between the two connectors 319C (FIG. 20) on the first board 31. In this case, the electrical path lengths from the 1-chip microcomputer to each connector 319C can be made close to equal distances, thereby suppressing the adverse effects caused by differences in electrical delay times.

The RF module 321 includes a microwave receiver 122 (FIG. 28) that receives radar waves in the microwave band emitted from a speed measurement device such as a mobile radar (hereinafter simply referred to as radar), and a radio signal at a predetermined frequency.

Such a built-in position is suitable for receiving radio waves and the like coming from the front of the vehicle.

In the radar detector 1, the RF module 321, which is covered with a metal casing to prevent noise, is connected to two left and right liquid crystal displays 152L and 152R in the thickness direction of the case body 2 (in the normal direction of the screen). It is arranged at a position overlapping the gap 152S (see FIG. 20). If the RF module 321, which is a heavy object, is arranged so as to overlap the gap 152S between the liquid crystal display sections 152L and 152R, the center of gravity will be located near the center of the case body 2 in the left-right direction, and this will make it easier to support it with the bracket 28. Improves weight balance. If such weight balance is achieved, the weight of the case body 2 can be supported with high reliability by the bracket 28, and shaking of the case body 2 due to vibrations of the vehicle can be suppressed.

At the four corners of the second board 32, through holes 326 are bored through which the screw supports 213 (FIG. 17) of the front frame 21 pass. This through hole 326 is formed to have a smaller diameter than the support column 221 of the case 22 (FIG. 18). In the assembled state, the second board 32 is supported in a state in which it is in contact with the end face of the support column 221 of the case 22 (FIG. 18), the end face of the cylindrical part of each hole such as the switch hole 253H, and the seat part 226. On the other hand, from the front frame 21 side, a seat portion 213A (FIG. 17) provided on the outer periphery of the screw support 213 is in contact with the second substrate 32. The second board 32 in the assembled state is thus sandwiched and fixed between the case 22 and the front frame 21.

Slit holes 322 and 323 for accommodating the ribs 222 and 223 of the case 22 are formed on the outer periphery of the second substrate 32. The slit holes 322 and 323 are incomplete through holes that open on the outer periphery of the substrate 32. The slit holes 323 are provided at positions corresponding to the ribs 223 provided on the upper and lower sides of the case 22, and are formed to accommodate the rib body portions 223B of each rib 223 (FIGS. 26 and 27).

When the memory card 171 storing updated data such as POI data and audio data is inserted into the memory card reader 17, the updated data is read out under the control of the control unit 10, and the data in the database 100 can be updated. Note that it is also possible to update the database 100 by connecting a PC with update data stored in a hard disk or the like via USB.

■ 4. Basic operation ■
The radar detector 1 realizes various functions by causing the CPU to execute software programs read from the ROM. The functions of the radar detector 1 include a current information display function, a GPS log function, an alarm function for issuing various warnings, an OBD function, a setting function, a registration function, and the like. As the alarm function, there are functions included in a general radar detector, such as a GPS alarm function, an RD alarm function, and a radio alarm function. Each means for realizing these functions is formed in the control section 10.

The current information display function is a function that displays current information by displaying a preset standby screen on the screen 15. Current information includes various information such as position information of surrounding targets (monitored position information), time information, tidal information, various vehicle information such as vehicle speed, fuel efficiency information, eco-driving information, satellite information, and altitude information. The current information displayed can be selectively set by selecting the standby screen. Setting of the standby screen is realized by a setting function described later.

The OBD function is a function to acquire vehicle information. This OBD function functions only when the radar detector 1 is connected to the vehicle side via an OBD adapter (FIG. 13) that is connected to the OBD connector on the vehicle side. By connecting the radar detector 1 to the vehicle using an OBD adapter, various vehicle information can be obtained every 0.5 seconds. Vehicle information that can be obtained from the vehicle side includes, for example, speed, average speed, maximum speed, 5 second speed, average 5 second speed, maximum 5 second speed, rotation speed, average rotation speed, maximum rotation speed, engine load, average load. , maximum load, throttle opening, average throttle opening, maximum throttle opening, ignition timing, fuel level, intake manifold pressure, maximum intake manifold pressure, MAF, INJ, cooling water temperature, maximum cooling water temperature, intake air temperature, maximum intake air temperature , outside temperature, maximum outside temperature, remaining fuel, fuel flow rate, maximum fuel flow rate, consumed fuel, lifetime fuel consumption, instantaneous fuel consumption, current fuel consumption, maximum current fuel consumption, lifetime fuel consumption, average fuel consumption, general road average fuel consumption, highway average fuel consumption , moving average fuel consumption, maximum moving average fuel consumption, driving time, driving time, idle time, idle ratio, mileage, lifetime mileage, 0-20km/h acceleration time, 0-20km/h average acceleration, 0-20km/h Shortest acceleration, 0-40km/h acceleration time, 0-40km/h average acceleration, 0-40km/h shortest acceleration, 0-60km/h acceleration time, 0-60km/h average acceleration, 0-60km/h shortest acceleration , 0-80km/h acceleration time, 0-80km/h average acceleration, 0-80km/h shortest acceleration, 0-20km/h driving time, 20-40km/h driving time, 40-60km/h driving time, 60 There is vehicle data such as -80km/h driving time, 80km/h or more driving time, lifetime engine mileage, lifetime engine mileage ratio, etc.

The GPS log function is a function that stores the current position output from the GPS receiver 121 every second in the database 100 as a position history. This position history is recorded, for example, in NMEA format. The stored current position is associated with the time and speed (vehicle speed) at which the control unit 10 detected the current position.
The registration function is a function for the driver, who is a user, to register personal points (my points) and areas (my area), and is executed by a registration means realized by software in the control unit 10.

The GPS warning function is a function that warns of approaching a warning target such as an Orbis (automatic speed control device). In the GPS alarm function, calculation processing for determining the distance between the location of the alarm target (implementation point) and the current location is repeatedly executed at predetermined time intervals (for example, 1 second). When this distance reaches a predetermined approach distance and an event called warning point approach occurs, a GPS warning indicating this event is executed.

Targets of alerts by the GPS alarm function include Orbis, enforcement areas, inspection areas, intersection monitoring points, parking monitoring areas, N systems, traffic monitoring systems, red light prevention systems, police stations, areas where accidents occur frequently, areas where targets on vehicles frequently occur, There are sharp curves, branching and merging points, and ETC lanes. Warning targets may include drowsy driving accident locations, radar, speed limit switching points, and the like.

Targets other than the alert targets of the GPS warning function include service areas (expressways), parking areas (expressways), highway oasis (expressways), smart interchanges (expressways), and gas stations in PA/SA (highways). roads), tunnels (expressways), highway radio reception areas (expressways), prefectural borders, roadside stations, view point parking, etc. In addition, in the radar detector 1 of this example, an arbitrary point can be registered or canceled as a My Area by a predetermined operation on the user side. Points registered as My Area are treated as targets, and an announcement will be made when you approach.

The RD alarm function is a function that warns of reception of radar waves (microwaves) emitted from a radar enforcement device. When an event in which the microwave receiver 122 receives a radar wave (hereinafter referred to as RD reception) occurs, an RD alarm indicating this event is executed.

The wireless warning function is a function to issue a warning so as not to interfere with the movement of emergency vehicles, etc. When an event of receiving radio waves emitted by an emergency vehicle or the like (hereinafter referred to as "wireless reception") occurs, a radio warning is issued to alert the driver. Warning targets include enforcement radio, car location radio, digital radio, special small radio, police radio, police telephone, police radio, tow radio, helicopter radio, fire helicopter radio, fire radio, emergency radio, highway radio, There is a security radio etc.

The setting function is a function to perform various settings regarding the radar detector 1. Settings include standby settings related to the standby screen, mode settings, alarm settings related to alarm operations, screen/LED settings related to the screen 15 and white LED 315B (operation button 24), audio settings, system settings, OBD settings, etc. Note that each setting will be explained in detail 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. Thereafter, a positioning information screen (not shown) is displayed until the current position can be determined by receiving GPS radio waves from a GPS satellite.

When the current position can be measured, the control unit 10 outputs a voice saying "Positioning has been 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 the left and right screens 15L and 15R, respectively, according to a setting operation described later.

The control unit 10 displays a standby screen on the left and right screens 15L and 15R in a standby state in which an event to be alerted such as RD reception, wireless reception, or approach to a warning point has not occurred. When any event among warning point approach, RD reception, and radio reception occurs in the standby state, the control unit 10 executes the corresponding function among the GPS alarm function, RD alarm function, and radio alarm function. The warning screen is displayed on the screens 15L and 15R. Note that when two or more events occur simultaneously, the priority of each function is from the highest to the RD alarm function, the wireless alarm function, and the GPS alarm function.
Further, when the vehicle ignition is turned on or when executing an alarm operation, the control unit 10 causes the white LED 315B installed in each operation button 24 to execute various light emitting operations (described later).

■ 5. Standby screen ■
In the radar detector 1, by touching the left and right touch areas 151S (FIG. 29) of each screen 15L, R, the standby screen of the screen 15 on which the touch operation was performed can be changed. When the control unit 10 detects a touch operation on any of the screens 15, the control unit 10 changes the standby screen of the screen 15 according to the annular arrangement order as shown in FIG. When the left touch area 151S is touched, the standby screen changes counterclockwise in the circular arrangement order, and when the right touch area 151S is touched, the standby screen changes clockwise in the annular arrangement order. change.

For example, on the screen 15 where the clock screen is set as the standby screen, when the left touch area 151S is touched, the standby screen is changed to the calendar screen on the left, and the right touch area 151S is touched. Sometimes I change the standby screen to the speed screen on the right.

Note that each standby screen in FIG. 29 can be set to either the left or right screen 15L or 15R. For example, it is also possible to set the same standby screen on the left and right screens 15L and 15R. When the same display screen is displayed on the left and right screens 15L and 15R, it is possible to use the screen 15 that is easier to see when it is difficult to see one of the screens 15 due to sunlight shining on the screen area. become. Since the left screen 15L is located near the passenger seat of a right-hand drive vehicle, it is also good to display the same display screen on the left and right screens 15L and 15R when a fellow passenger is present.

Next, the specifications of each display screen that can be set as the standby screen will be explained.
(1) Radar scope screen The radar scope screen shown in Figure 30 is a display screen that graphically displays information (monitoring position information) representing the positional relationship with the current position when approaching a target registered in the radar detector 1. be. On the radar scope screen, a scope surface corresponding to the area surrounding the current position is displayed, and a target icon representing the implementation point of the traffic monitoring activity, etc., and an own vehicle icon representing the current position are plotted and displayed on the scope surface. Target information, which is text information about the target type, and the distance to the target are displayed in the upper row. The current traveling speed (vehicle speed) is displayed on the lower left, and the speed limit is displayed on the upper side of the display field.

In the case of the radar scope screen of the right screen 15R, the current time is displayed on the lower right. Note that the display color (character color) of the traveling speed is changed depending on whether the speed is over or not, and when the speed is over, the characters are displayed in red.

Note that if the radar scope screen is displayed on one screen 15 and a standby screen other than the radar scope screen is displayed on the other screen 15, the display of target information etc. on the radar scope screen is omitted, It is also good to display a telop (for example, reference numeral 41 in FIG. 42) containing target information on another standby screen. In this case, the radar scope screen can be displayed in an easy-to-understand manner by ensuring a wide display area on the scope surface.

(2) Clock screen The clock screen in FIG. 31 is a display screen that displays the current time. In addition, in the case of the right screen 15R, the speed is displayed at the bottom of the clock screen. However, when GPS positioning is disabled, the speed is not displayed. The control unit 10 adjusts the time displayed on the clock screen.

(3) Speed screen The speed screen in FIG. 32 is a display screen that displays the speed of the vehicle. In the case of the right screen 15R, a clock is displayed at the bottom of the speed screen. On the right side of the display column that numerically displays speed, there is a vertical segment display that represents the degree of speed. The control unit 10 increases the number of segments displayed on this segment display as the speed increases. Note that since the control unit 10 calculates the speed using GPS radio waves, the speed display is 0 km/h in places such as inside a tunnel where GPS radio waves cannot be received.

(4) Eco-drive screen The eco-drive screen shown in FIG. 33 is a display screen that displays eco points that are indicators of the degree of achievement of fuel-efficient driving. The control unit 10 calculates eco points based on sudden acceleration, sudden deceleration, idling time, economical speed, etc. A speed display field is arranged to the right of the eco point display field. This speed becomes 0 km/h when GPS positioning is not performed. In addition, in the case of the right screen 15R, a clock is displayed at the bottom of the eco-drive screen. Note that the control unit 10 calculates eco points using GPS radio waves.

(5) Altitude screen The altitude screen in FIG. 34 is a display screen that displays the altitude of the vehicle. The control unit 10 displays the change in altitude in a graph. Note that in the case of the right screen 15R, a clock is displayed at the bottom of the altitude screen. Since the control unit 10 calculates the altitude using GPS radio waves, the altitude display is fixed to the previous value in places such as inside a tunnel where GPS radio waves cannot be received.

(6) Atmospheric pressure screen The atmospheric pressure screen in FIG. 35 is a display screen that displays the current atmospheric pressure. The control unit 10 displays the current atmospheric pressure value as well as past atmospheric pressure changes in a graph.

(7) Positioning Information Screen The positioning information screen in FIG. 36 is a display screen that displays the reception status of GPS radio waves. The control unit 10 displays the satellite number and reception level of the satellites receiving GPS radio waves. Note that the satellite number is a number assigned to a satellite.

(8) Satellite Information Screen The satellite information screen in FIG. 37 is a display screen that displays information about the satellite being received. The control unit 10 displays the satellite number, type (GPS, QZSS, SBAS, GLONASS), elevation angle (Elev.), and azimuth angle (Azim.). The control unit 10 periodically switches and displays the display screen and displays the satellites in order.

(9) OBD meter screen The OBD meter screen in 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 left touch area 151S of the screen 15 that displays the satellite information screen is touched, the OBD meter screen is displayed, while when the OBD adapter is not connected, The OBD meter screen and the next OBD fuel efficiency 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, and outside air temperature, as shown in Figure 38. , engine oil temperature, instantaneous fuel consumption, average fuel consumption, current fuel consumption, etc.

(10) OBD Fuel Economy Information Screen The OBD fuel economy information screen in FIG. 39 is a display screen that displays instantaneous fuel consumption and average fuel consumption calculated by the control unit 10 using vehicle information. Vehicle information is acquired via the OBD adapter, so if the OBD adapter is not connected, it will not be switched and displayed, similar to the OBD meter screen. On the OBD fuel efficiency information screen, two types of fuel efficiency are displayed in upper and lower levels. In each stage, a numerical display of fuel efficiency and a segment display of the degree of fuel efficiency are arranged above and below. Examples of combinations of two types of fuel efficiency include a combination of instantaneous fuel consumption and average fuel consumption, a combination of instantaneous fuel consumption and current fuel consumption, and a combination of current fuel consumption and average fuel consumption.
In addition to the above, the standby screen includes a calendar screen that displays the date, etc., and an OFF screen that makes the screen 15 completely black (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 a status icon on the left screen 15L. However, when the left screen 15L is a radar scope screen, OBD meter screen, or OFF screen, a status icon is displayed on the right screen 15R. If the left and right screens 15L and 15R are either a radar scope screen or an OBD meter screen, no status icon is displayed.

Further, as target icons displayed on the radar scope screen by the control unit 10, there are icons illustrated in FIG. 41. Each target icon has a different display color depending on the degree of caution (degree of necessity for notification), and the degree of caution increases in the order of green → blue → yellow → red. The degree of caution is determined in advance according to the type (content) of the traffic monitoring activity related to the target.

Note that on some standby screens, it is possible to select the display color of characters from among six preset colors. Furthermore, it is possible to set the standby screen to automatically switch and display each standby screen at regular intervals (for example, one minute).

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

(1) Two-screen warning The display pattern of the two-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 reports the type of target and the distance to the target. , is a display pattern that simultaneously displays . On the notification panel screen, a telop (text information) 41 that displays the target type (monitoring type information) and distance in text is displayed at the top, and an illustration 42 representing the target type is displayed in the center. Furthermore, the time is displayed at the bottom right. The illustration 42 is displayed based on illustration data stored in the database 100.

There are three methods for displaying the two-screen warning display pattern: The first method is to press and hold the VIEW button 243 to display the screen. The second method is to select "Radarscope" for the left screen 15L, and set "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 to set "radar scope" for the left screen 15L, and set "display switching distance → set distance" and "target information → notification panel" for the right screen 15R. In this method, when the distance between the own vehicle and the target reaches the distance set in the display switching distance, the display pattern switches to the two-screen warning display pattern.

In the two-screen warning, a radar scope screen is displayed on one screen 15, and a notification panel screen is displayed on the other screen 15. For example, in other radar detectors that only have one screen, it is necessary to use part of the radar scope screen to display target information such as target type and distance. If it is a two-screen warning, target information can be displayed separately from the radar scope screen. With such a display specification, a wide display area of the scope surface can be ensured on the radar scope screen, making it easy to grasp the position of the target, and displaying target information becomes very easy to understand.

(2) 1-screen warning part 1
The display pattern for this one-screen warning No. 1 is as shown in Figure 43. The radar scope screen displays the own vehicle position and the target position, and a ticker 41 is displayed at the top of the standby screen to inform the target type and distance. It is a setting. In the radar detector 1 of this example, the initial setting is a one-screen warning No. 1 display pattern in which a clock screen is set as the standby screen.

There are the following two methods for displaying the display pattern of the one-screen warning No. 1. The first method is to set <<Radarscope>> for the left screen 15L, and set <<Display switching distance → No switching>> and <<Target information → Telop>> for the right screen 15R. The 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 host vehicle and the target reaches the distance set in the display switching distance, a warning screen as shown in FIG. 43 is switched and displayed. It should be noted that which screen 15L or 15R, the right or left screen, the telop 41 should be displayed on can be selectively set by the user's operation.

(3) 1-screen warning part 2
As shown in FIG. 44, this one-screen warning No. 2 display pattern is such that the left screen 15L displays a standby screen, and when an alarm occurs, a notification panel screen is displayed on the right screen 15R. This one-screen warning 2 can be displayed by setting the standby screen other than the radar scope screen on 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 15R the notification panel screen is to be displayed on can be set using the <<Notice Display>> setting item.

(4) No warning screen The display pattern without a warning screen is as shown in FIG. This is a display pattern in which only the subtitle 41 is displayed on the screen (example of 15R). For the display pattern without warning screen, set the standby screen other than the radar scope screen for both the left and right screens 15L and R, and set ``Display switching distance → no switching'' and ``Target information → telop'' for the right screen 15R. can be displayed. Which of the left and right screens 15 the telop 41 should be displayed on can be set using <<Notification Display>>.

■7. Alarm action ■
(1) Alarm operation when receiving enforcement radio waves When receiving enforcement radio waves such as radar waves or stealth waves, the control unit 10 executes alarm operations such as displaying a warning screen on the screen 15 and outputting an alarm sound. . FIG. 46 is an example of a warning on 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 warns with both sound (electronic sound/warning voice) and screen display. The control unit 10 changes the scope surface of the radar scope screen to red, and displays a subtitle 41 indicating the type of traffic monitoring activity at the top of the radar scope screen. This telop 41 includes an indication (for example, L5) of the reception level of radio waves such as radar waves.

Note that when a predetermined mute operation is performed during the warning, the control unit 10 executes control to temporarily mute the warning sound until the radar wave that is being received is no longer received. Examples of the mute operation include a hand-holding operation in which the user holds the hand over the screen area 15A (FIG. 1) for a certain period of time (one second), a long-press operation on the MUTE button 248, and the like. Further, when the reception of radar waves continues for about 30 seconds or more, the control unit 10 automatically executes control to reduce the volume of the alarm sound.
In addition, as shown in FIG. 47, in the alarm operation when the enforcement radar wave is received, the control unit 10 controls the electronic Executes control to increase the tempo of the sound.

(2) Warning operation when approaching a target When the distance between the host vehicle and the target becomes small (when the vehicle approaches the target), the control unit 10 displays a caption 41 that displays target information and distance in text, as shown in FIG. It is displayed at the top of the screen 15.

FIG. 4(a) is an example in which ``telop display'' is set for the clock screen that is set as the standby screen. FIG. 6B shows an example of the radar scope screen when "telop display" is set. In addition, 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. 2C shows a change in the background color of the screen 15 controlled by the control unit 10 depending on the warning level. 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 approximately 25 degrees or more in the right or left direction with respect to the direction of travel (see FIG. 49), Add the phrase "to the right" and execute control to announce the direction (orientation of the implementation point). The "right direction" and "left direction" voices are the direction of the target at the time of announcement. Note that if the distance to the target is very short, a phrase for identifying left and right directions may not be added. Here, "" means an audio output using an alarm voice.

The alarm voice is output at each timing shown in FIGS. 50 to 53. In FIG. 50, warning voices related to Orbis (speed violation enforcement) are shown in the upper row, and warning voices related to the enforcement area are shown in the lower row.
For example, in the case of an Orbis warning voice, the following stages are set: 2 km ahead (expressway only), 1 km ahead, 500 m ahead, just before, and passing, 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, the distance, such as "2 km ahead", is output as a voice. Further, at 1 km ahead, in addition to the distance audio output, a warning voice is output to notify the speed limit or speed exceedance, and at 500 meters ahead, a warning voice is output to notify the camera position. If the speed is exceeded immediately before, the control unit 10 executes control to output a warning voice for overspeed notification in addition to notification of the immediately preceding travel speed.

For example, in the case of a warning voice for a control area, each stage of 1 km ahead, area entry, and area exit is set, and the warning voice is output for each stage under the control of the control unit 10. At the stage of 1 km ahead, a warning voice is output to indicate whether the area is located in the left or right direction. 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 enforcement/inspection area at the bottom of the display screen.

Note that the audio output (utterance) such as the alarm voice can be muted by holding the hand over the screen area 15A (FIG. 1). When the proximity sensor 125 disposed in the gap 152S (FIG. 20) between the left and right liquid crystal displays 152L and 152R detects a human body and the duration of the detection state reaches 1 second, the control unit 10 outputs audio. Mute and control so that it is not output. If a threshold value such as 1 second is set for the duration of the detection state, for example, there is less risk of erroneously detecting the movement of a driver's hand when he or she takes his or her hand off the steering wheel to operate an audio device or the like.

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

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

(1) Easy mode setting When the easy mode (easy setting mode) is set to on as shown in FIG. 55, the mode becomes a simple setting mode with only easy settings, and easy settings are 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 extremely simple, as they only allow you to change the brightness of the display screen, the type of radar warning sound (electronic sound/voice), and view the software version.

(2) Mode setting The radar detector 1 has a manual mode in addition to four preset alarm modes (normal, minimum, special, and all-on). Users can set their favorite alarm mode by operation. The normal mode is an alarm mode with settings that place emphasis on balance. Minimum mode is an alarm mode in which only the minimum number of items are set to on. The special mode is an alarm mode with settings that place emphasis on items related to enforcement. All-on mode is an alarm mode in which all functions are set to on. 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 figure) is displayed as shown in FIG. 56, 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 the display to the mode screen (bottom left diagram). After the desired alarm mode is selected, when end of setting is selected (bottom right diagram), the control unit 10 executes control to return to the original standby screen display state. Note that the contents of each alarm mode are as shown in FIG.

(3) Alarm Settings In the alarm settings, as shown in FIG. 58, each item such as reception sensitivity mode, road selection, display switching distance, target information, and notification display can be set.
The reception sensitivity mode can be selectively set to ``City,'' which is suitable for urban areas, ``Extra,'' which is suitable for suburban areas and highways, and ``AAC/ASS,'' which cuts unnecessary alarms and automatically sets the optimal reception sensitivity.

When selecting a road, the target road for the GPS warning can be selected from among "general roads", "expressways", "ALL", "AUTO GPS priority", and "AUTO pressure priority". With the "General Road" setting, only targets on public roads will be alerted. With the "Highway" setting, only highway targets will be alerted. With the setting <<ALL>>, all targets on public roads and highways are alerted. The <<AUTOGPS priority>> setting is a setting in which the control unit 10 automatically identifies the type of road (general road or expressway) on which the vehicle is traveling by preferentially using GPS position information. The <AUTO atmospheric pressure priority> setting is a setting in which the control unit 10 automatically identifies the type of road (general road or expressway) on which the vehicle is traveling by preferentially utilizing changes in atmospheric pressure. The control unit 10 executes control to issue a warning only to the target on the general road when it can be identified as a general road, and to issue a warning only on the target on the expressway when it can be identified as an expressway. Other setting items are as shown in the figure.

As the display switching distance, one of the following distances can be selectively set: "No switching," "500 m," "1000 m," and "1500 m." By setting the display switching distance, you can switch the display from the preset standby screen to the notification panel screen, etc. when the distance from your vehicle to the target becomes short, as explained in "6. Warning screen". can be executed. For example, in the two-screen warning in Figure 42, if "Radarscope" is set for the left screen 15L, and "Display switching distance → set 1000 m" and "Target information → notification panel" are set for the right screen 15R, the control The unit 10 executes control to display a notification panel screen including a subtitle 41 of target information in place 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 settings In the screen/LED settings, as shown in FIG. 59, each item of screen brightness, screen inversion, screen color setting, LED mode, and LED brightness can be set. For example, the screen brightness can be selectively set to ``minimum'', ``dark'', ``normal'', or ``bright''. As for the LED mode, any one of ``Alarm/Touch ON'', ``Always ON'', and ``OFF'' can be set. Other setting items are as shown in the figure.

Here, the contents of each setting of the LED mode will be explained with reference to FIG. 60. As mentioned above, there are three types of LED mode settings: "Alarm/Touch ON", "Always ON", and "OFF". This figure is a diagram illustrating the operation details of the white LED 315B in each of the operating states 1 to 3 for each of these three types of settings (control modes).

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

Both the hand-holding operation to turn on the white LED 315B in the standby state and the hand-holding operation to mute the audio output are performed as long as the detection state of a human body etc. by the proximity sensor 125 continues for a predetermined duration. When this happens, the control unit 10 determines that an operation has been performed. The predetermined duration time is set to 1 second as described above for the mute hand holding operation. Regarding the hand holding operation in the standby state, it is preferable to set a time shorter than 1 second, for example. Regarding the mute operation, it is necessary to avoid the possibility that the hand operating the car audio etc. will be mistakenly detected and the alarm voice etc. will be muted, but the hand operation in standby mode is slow. This is because it is necessary to give priority to the operation response so as not to give a negative impression.

When any of the operation buttons 24 is touched after the hand holding operation etc. is performed in the standby state (state 1) as described above, the control unit 10 lights up the white LED 315B only for the operated operation button 24. Control is executed to turn off the light and return it to the lighted state upon completion of the touch operation. Thereafter, 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 be made to blink for a predetermined period of time when the touch operation is completed. This makes it easier for the user to know that the operation has been accepted.

In state 2, which corresponds to an alarm, the control unit 10 executes control to blink all the white LEDs 315B. In addition, if the location (implementation point) of the traffic monitoring activity to be alerted has a directionality such as left, right, or forward, for example, only the left white LED 315B may be blinked, or only the top two white LEDs 315B may be blinked. It is also effective to perform control such as blinking.
Note that during the warning, for example, control may be executed to blink all the white LEDs 315B according to the alertness level (need level of notification) of the warning target. By slightly varying the lighting timing of the operation buttons 24 arranged at five locations on the outer periphery of the screen area 15A, control can be executed such that the lighting position circles around the screen area 15A during an alarm. good. Furthermore, the higher the level of caution, the faster the circling cycle may be to create a sense of urgency. Alternatively, when entering an area where traffic accidents occur frequently, the five operation buttons 24 may be turned on at random to intuitively express a high-risk situation.

In state 3, which corresponds to power-on in response to switching on of the vehicle ignition, the control unit 10 executes control to blink all the white LEDs 315B, and then executes control to turn them all off when a predetermined time has elapsed. Note that the blinking of the white LED 315B is realized not by complete periodic switching of on and off, but by control of periodically changing the brightness. By controlling the brightness to change periodically, it is possible to blink the light like a firefly (it is better to make the blinking cycle faster than a firefly), giving the device a high-class feel.

In the <Always ON> LED mode, the control unit 10 executes control to light up 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 is executed to blink the white LED 315B.

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

(5) Audio settings The audio settings are settings related to the output mode (output mode) of various sound information such as sounds such as alarm voices and sound effects. In the audio setting, as shown in FIG. 61, it is possible to set various items such as speech speed (speech speed), narrator switching, radar warning sound, positioning announcement, RELAX chime, time signal, operation sound, and target approach sound. The speech speed of the alarm voice can be switched in four stages: ``slow'', ``normal'', ``fast'', and ``alarm-linked''. In particular, in <Alarm Linkage>, the speaking speed changes depending on the type of alarm. When switching narrators, the alarm voice can be switched between ``female'' and ``male.'' For radar warning sounds, you can switch between ``voice'' and ``electronic sound'' when the radar is received.

For positioning announcements, you can select whether to turn positioning announcements on or off. For example, if the reception of GPS radio waves is poor, such as in a canyon between buildings, positioning announcements such as ``Unable to receive GPS'' and ``GPS received'' may be repeated, but if you turn off positioning announcements, such repeats may not occur. It can be avoided. The RELAX chime is a function that prompts you to take a break at regular intervals. It is possible to select the time interval for audio output. The time signal is a function that notifies the time on the hour every hour, and it is possible to select whether or not to use the time 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 approach sound is a sound output when the target approaches, and the target approach sound is output according to the ON setting.

As mentioned above, the speaking speed of the voice setting (FIG. 62) can be selectively set to one of the four types: "slow", "normal", "fast", and "alarm-linked". When <<Normal>> is set, the control unit 10 outputs the warning voices of all announcements at a speaking speed of 100% (average speed). When "slowly" is set, the control unit 10 outputs the warning voices of all announcements at 90% speaking speed. When "Fast" is set, the control unit 10 outputs all announcement warning voices at 120% speaking speed.

Note that the speaking speed of 100% means the normal speaking speed, and the speaking speed of 120% means that the speaking speed is 120%. Note that, in the radar detector 1 of this example, audio data obtained by digitally recording actual utterances by a narrator is recorded in the database 100. The voice data in the database 100 is record data corresponding to a speaking speed of 120%. If the voice data is played back as is, the speaking speed will be 120%. If the audio data is played back about 20% slower, the speech speed becomes 100%, and when it is played back even 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 a speech rate of 120% in the database 100. Of course, voice data corresponding to a speech rate of 100% may be recorded in the database 100, or voice data exceeding the speech rate to be actually output, such as 130% speech rate, may be recorded in the database 100.

When <<alarm interlock>> is set, the control unit 10 changes the speaking speed according to the type and situation of the traffic monitoring activity to be alerted, as shown in FIG. 62. In the same figure, the stealth notification and the RD notification are the warning operations when receiving the control radio wave (1) explained 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/control notification, and my area notification are the warning actions when approaching the target in 2) of "7. Alarm actions". In the figure, “All sound effects” (fourth row from the bottom) in the notification content column is the same as the sound effect in the phrase “(sound effect) Stealth reception Stealth reception” in the phrase example column. (For example, it means ``Pon''). For example, in the case of a stealth announcement, the control unit 10 outputs a sound effect at 100% speed, and then outputs the phrase "Stealth reception Stealth reception" at 120% speech speed.

For example, in the case of an RD notification, the control unit 10 outputs a phrase such as "Please be careful of your speed" after outputting a sound effect at 100% speed. At this time, the control unit 10 changes the speaking speed of phrases such as "Please be careful about speed enforcement" according to the reception level (L1 to L5) of the radar waves. For example, in the case of reception level 1 or 2, the degree of caution is not so high, so the control unit 10 outputs the sound effect of 100% speed, and then outputs the phrase "Please be careful about speed enforcement". is output at 90% speech speed. In the case of reception level 3, the control unit 10 outputs a sound effect at 100% speed, and then outputs the phrase "Please be careful of your speed" at 100% speech speed. If the reception level is 4 or 5, the degree of caution is high, so the control unit 10 outputs a 100% sound effect and then outputs a message saying "Be careful when driving" or "Slow down." Output phrases at 120% speaking speed. The control unit 10 outputs an alarm voice every time the reception level changes, such as from reception level 2 to 3.

Note that reception levels 1 and 2, which set the speaking speed of the latter half of the phrase to 90%, correspond to reception levels from a radio wave generation source such as an automatic door. The radar detector 1 suppresses the speech rate to less than 100% because there is a possibility of a false alarm when an RD announcement is made at such a reception level.

The control unit 10 controls the speed of the sound effect to be 100% constant regardless of the speaking speed of the following phrase. In this way, if the output mode of the sound effect that triggers the alarm operation is set to exactly the same specifications regardless of the speaking speed of the phrase, the sound effect that means the start of the alarm operation can be strongly impressed on the user, and the alarm This has the effect of suppressing the possibility that the message will be missed.

By changing the speaking speed of phrases as described above, it is possible to change the user's impression of the utterance. For example, by setting a fast speech rate, you can create a sense of urgency and give the impression that you are paying attention. In this example, the degree of caution is defined depending on the type of traffic monitoring activity to be alerted, and the display color of the target icon is set in accordance with the degree of caution (FIG. 41). It is also good to change the speaking speed depending on the display color of the target icon. For example, for traffic monitoring activities where the level of attention is low and the display color of the target icon is green, control may be applied such as always setting a slow speaking speed and not changing the speaking speed.

For example, in the case of an Orbis announcement, the control unit 10 changes the speaking speed depending on the distance to the Orbis and whether or not the vehicle is overspeeding. The closer the distance is, the faster the phrase that follows the sound effect is spoken, and in the case of overspeeding, the speaking speed of the phrase is set faster than when the speed is not overspeeding.
For example, in the case of an inspection/control announcement, the control unit 10 changes the speaking speed of the phrase depending on whether the vehicle speed is greater than or equal to 52 km/h or less. When the vehicle speed is 52 km/h or more, the speaking speed is made faster than when the vehicle speed is less than 52 km/h.

Regarding the target approach sound (distance-linked Orbis sonar sound shown in FIG. 63) in the audio setting, it is possible to selectively set it to "on" or "off". When the target approach sound is set to <<ON>>, the control unit 10 outputs a sonar sound when the target approaches the Orbis, as shown in the figure. After executing the Orbis notification when the distance to the Orbis becomes 1 km or 2 km, the control unit 10 outputs the Orbis sonar sound at a transmission cycle of 1 Hz if there is no other notification. At this time, the volume of the Orbis sonar sound is set to minus 8 dB with respect to the volume of the Orbis notification. When the distance to 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 frequency of the Orbis sonar sound according to the distance, increases it to 2.5Hz when it reaches 200 m, and then stops outputting the Orbis sonar sound in response to the passage of the Orbis. . By changing the transmission cycle of the Orbis sonar sound in conjunction with the distance to the Orbis in this way, it becomes possible to grasp the level of caution from the Orbis sonar sound alone. Even if you miss the distance reported by the Orbis notification, you will be able to grasp the distance from the Orbis sonar sound.

(6) System Settings In the system settings, various system settings can be made as shown in FIG.
(7) OBD settings In the OBD settings, as shown in FIG. 65, it is possible to set the OBD meter for each screen 15, fuel efficiency information, coefficient correction, and data deletion. When an OBD meter is set, the vehicle information to be displayed includes vehicle speed, engine speed, engine load, throttle opening, fuel level, intake manifold pressure, coolant temperature, intake air temperature, outside temperature, engine oil temperature, instantaneous fuel consumption, You can selectively set either the average fuel consumption or current fuel consumption. For example, regarding 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 same figure.

The radar detector 1 of this example configured as described above includes screens 15L and 15R for displaying monitoring information regarding 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 caption 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 it easier to understand monitoring location information. has been improved. By using the plurality of screens 15L and 15R in this way, monitoring information can be reported in an easy-to-understand manner.

Furthermore, the radar detector 1 can 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 the user's attention can be attracted, it is possible to reduce the risk that the monitoring information to be reported will not be recognized by the user and will be overlooked.

The radar detector 1 changes the output mode of sound information such as a warning voice depending on the degree of caution (degree of necessity 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 outputted compared to the case where the sound information is output in exactly the same output mode. For example, by changing the speaking speed, information about differences in attention levels can be reported. Furthermore, if there is a difference in the output mode of the sound information, the user can intuitively recognize the difference.
As described above, the radar detector 1 of this example has an excellent characteristic of being able to provide easy-to-understand monitoring information regarding traffic monitoring activities.

The radar detector 1 has an accommodation structure in which ribs are accommodated in slit holes provided on the outer periphery of the substrate. This accommodation structure realizes a contact structure between the outer circumferential surface of the rib and the inner circumferential surface of the slit hole of the substrate. If such a contact structure is provided, it can be expected that the rigidity (particularly torsional rigidity) of the casing (case body 2) will be improved by utilizing the strength of the board. Note that the rib may be configured to stand up on the bottom surface of the case 22 without being connected to the inner circumferential side surface. The through hole on the substrate side 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 15R are arranged parallel to each other on the same plane. Instead of this configuration, the positions of the screens 15L and 15R may be changed in the thickness direction (depth direction) of the case body 2. For example, it is also good to arrange the screen 15R 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 screen 15 on the near side may be formed transparent. In this case, image information with a sense of depth can be displayed using two screens that overlap in the depth direction.

Furthermore, it is also good to arrange the screens on different sides of the dice-shaped housing. Furthermore, it is also good to employ a bracket that rotatably supports the housing. In this case, the image information visible to the user can be switched depending on the orientation of the dice-shaped housing.

The front surface of the case body 2 may be raised at the center in the left-right direction so as to be located on the front side in the depth direction, and may also be formed with an inclined surface that is located on the back side in the depth direction toward both left and right sides. If screens are installed on the slopes formed on both sides of the center in the left and right direction, for example, if a radar detector is installed in the middle of the dashboard, one screen will face the driver, while the other screen will face the driver. The screen now faces the passenger side of the front passenger seat, improving visibility for both the driver and passenger. In this case, it is also good to display the same display screen on each screen. Also, if the screen orientations (normal directions) are different in this way, for example, in a situation where one screen is reflecting sunlight, it is possible to avoid sunlight reflecting on the other screen. It gets expensive.

In the radar detector 1 of this example, the operation buttons 24 by the operation unit 315 including the white LED 315B are arranged on both the left and right sides of the screen area 15A where the screens 15L and 15R are arranged. For example, the direction of the target may be indicated depending on which operation button 24 is lit or flashed. For example, if the target is on the left with respect to the direction of travel 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. . By indicating the direction by blinking the operation button 24, etc., it is possible to realize an easy-to-understand notification that allows the user to grasp the direction 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, it is possible to perform control such that, for example, the illuminated operation buttons 24 revolve around the screen area 15A. For example, when issuing a warning regarding traffic monitoring activities, it is also possible to change the cycle at which the lighting position circulates depending on the degree of caution, so that the higher the degree of caution, the faster the cycle is made. In this case, the user can recognize the degree of attention at a glance.

Note that the easy mode of the radar detector 1 of this example is a simple setting mode in which the standby screen of each screen 15 cannot be selected. Under easy settings, 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 radar scope screen is displayed on the left screen 15L. A telop 41 is displayed (FIG. 43). In this way, under the easy setting of this example, the display screen of each screen 15 is fixed, but an intermediate easy setting mode has been added that allows you to selectively set two to three types of standby screens, for example. It's also good to do. The simple settings in this example are not enough, but a mode that allows all settings can meet user needs that are too complex. While the display screen of the left screen 15L is fixed to the radar scope screen, the display screen of the right screen 15R may be made selectable as a standby screen.

Note that the radar detector 1 of this example has a touch sensor for detecting a touch operation corresponding to each operation button 24, as well as a proximity sensor for detecting a hand-holding operation, etc. We are prepared. It is also possible to employ a capacitive touch sensor for each operation button 24 and to detect a hand holding operation using these touch sensors. In this case, it is preferable to change the detection distance of the touch sensor between the state of waiting for a hand holding operation and the state of waiting for a touch operation. For example, while waiting for a hand-holding operation, the detection distance is set long, and after the hand-holding operation is detected, if the detection distance is brought closer to zero, a touch operation on each operation button 24 can be detected with high reliability.

It is also possible to navigate the operations by sequentially lighting up the operation buttons 24 to be operated next by utilizing a configuration in which the lighting of each operation button 24 can be individually controlled. For example, various settings such as ``Set dual-screen warning'' and ``Set alarm-linked speech speed'' are displayed as a selectable list, and when one of the settings is selected, that setting is displayed. It is also good to light up the operation buttons 24 to be operated in order. In this case, the user can perform desired settings simply by operating the illuminated operation buttons 24 in sequence.

It is also good if the radar detector 1 of this example includes a map display function. It is also possible to display a map on which a target icon is plotted on one screen, and display a subtitle displaying information about the target icon on the other screen. Also, for example, maps with different scales may be displayed on multiple screens. A wide-range map display is suitable for grasping the positional relationship between the target and the own vehicle, and a narrow-range map display is suitable for grasping the distance to the target with high accuracy. Further, for example, a target icon with a specified implementation point may be displayed on a map on one screen, and a target with a designated area may be displayed on a map on the other screen. In general, for targets with identified implementation points, it is necessary to display pinpoint locations, so plotting on a narrow map is appropriate, while for targets with designated areas, the entire area is shown. Since this is necessary, a wide-range map display is suitable.
