Description

  The present invention relates to an in-vehicle electronic device that can be applied as, for example, a radar detector, a navigation device, or the like.

  In recent years, many speed measuring devices for measuring the speed of an automobile have been installed around the road. As an example of a speed measuring device, a microwave of a predetermined frequency band is emitted toward a vehicle, and the reflected wave is received to measure the traveling speed of the vehicle.

  On the other hand, in order to detect the presence of such a speed measuring device, a microwave detector configured to detect a microwave emitted from the speed measuring device and output an alarm is conventionally known. However, depending on the installation location of the speed measurement device, road conditions, and other surrounding environments, conventional microwave detectors can be detected from a relatively long distance, and can be detected only after a relatively close distance. .

  Also, some velocity measuring devices cannot be detected by conventional microwave detectors. As an example, there is a type in which a loop-shaped coil is embedded in the ground and a vehicle speed is determined while detecting the vehicle passing over the coil, as called a loop type. Others detect the speed of the vehicle using light other than microwaves.

  Therefore, recently, when GPS (Global Positioning System) information is used, the installation position information of the speed measurement device is stored in advance, and the current position approaches the stored installation position (when a predetermined relationship is established) In addition, there is an in-vehicle electronic device that issues a warning regardless of whether or not microwaves are detected (Patent Document 1).

  For example, when the current position is within 1000 m from the installation position of the speed measurement device, the first warning is given, and when the current position is within 500 m from the installation position of the speed measurement device. Do a second warning, etc.

JP 2008-64588 A

  However, in such an in-vehicle electronic device, the installation position information of the speed measuring device issues a warning based solely on information on the latitude and longitude. Therefore, a warning is issued only when the distance between the speed measuring device and the current position approaches the distance to be warned, and the existence of the speed measuring device cannot be known in advance.

  Moreover, since the installation position information of the speed measuring device is simply information on the latitude and longitude, even if a warning is issued, the warning target speed measuring device is on the road that is currently running. Not limited to this, it may be on a nearby non-traveling road.

  Therefore, there is a problem that it is difficult to predict a warning point on a running road in advance.

For example, when a large number of speed measuring devices are set along the main road, there are sections where the warning is given many times and noisy when traveling on the main road. Even in such a case, it has not been possible to cancel the warning so as not to warn only points that do not require a warning on the traveling road.
As described above, there was a bad aspect of usability regarding warning.

  Therefore, the present invention has been made to solve such a problem, and an object thereof is to provide an in-vehicle electronic device such as a radar detector that is easier to use than conventional ones.

In order to achieve the above-described object, an in-vehicle electronic device according to the present invention includes (0) a start position setting unit that sets a start position of a route search, an end position setting unit that sets an end position of a route search, Storage means for storing map information including road position information for route search and information on warning locations, and a start position set by the start position setting means to an end position set by the end position setting means. Route search means for searching for a route based on map information stored in the storage means, route display means for displaying at least part of the route searched by the route search means, and position detection for detecting the current position Warning means for issuing a warning based on the current position detected by the means, the current position detected by the position detection means, and information on the warning location stored in the storage means, A warning mode setting unit that displays the warning part necessary when passing the route searched by the route search unit and sets a warning mode of the displayed warning part based on an input from the user. In the on-vehicle electronic device, the warning means is configured to be capable of warning by light and warning by sound. As the warning mode, a warning warning by sound, a warning by light and a warning by sound are provided. The warning mode setting means displays a plurality of warning locations existing on the route, receives a selection of a warning location to be set from the user, and is selected from the plurality of warning locations. The warning mode can be set for each warning location, and the warning unit is configured to issue a warning based on the warning mode set in the warning mode setting unit, It was.
(1) Stores map information including start position setting means for setting a start position of route search, end position setting means for setting an end position of route search, road position information for route search, and information on warning points. And a route search for searching a route from the start position set by the start position setting unit to the end position set by the end position setting unit based on the map information stored in the storage unit Means, route display means for displaying at least part of the route searched by the route search means, position detection means for detecting the current position, current position detected by the position detection means, and storage in the storage means An in-vehicle electronic device comprising warning means for issuing a warning based on the information relating to the warning location, and searched by the route search means. A warning mode setting unit configured to display the warning part required when passing through the route and set a warning mode of the displayed warning part based on an input from a user, and the warning unit includes the warning mode It is set as the structure which issues a warning based on the warning aspect set to the setting means.

  According to the present invention, at least a part of the route from the start position to the end position is displayed, and a warning part necessary for passing through the route is displayed. Therefore, it is possible to know in advance the warning location when passing the route. For example, in a conventional radar detector, a warning or the like can be performed only at a point 500 m or 1000 m before the warning point, and the warning point cannot be predicted in advance. However, if the present invention is applied, the warning point is predicted in advance. be able to.

  In this way, the warning mode of the displayed warning location can be set based on the input from the user, and a warning based on the set warning mode is issued. Therefore, a warning in a warning mode desired by the user is issued, and dissatisfaction with the warning mode that the user has can be prevented or eliminated in advance.

  (2) The warning mode may include a mode in which no warning is given.

  (3) The warning means is configured to be capable of warning by light and warning by sound, and may include a mode in which warning by sound is not performed as the warning mode.

  If it carries out like said (2) and (3), it can prevent beforehand that a user feels it annoying to sound a warning sound. In addition to this, for example, it is preferable to be able to set the volume, or to set as a warning mode whether to give a warning by voice or electronic sound.

  The warning location may be displayed at a position stored in the storage means as the location of the warning location itself, or at a location corresponding to the location where the warning is issued on the route. For example, if there is a warning part that is a warning target when it is slightly away from the route but within a predetermined distance from the route, it is displayed at a position corresponding to the position of the warning part itself that is away from the route. Alternatively, it may be displayed at a position that first reaches the predetermined distance on the route.

  (4) The warning mode setting means can display a plurality of warning locations existing on the route and set the warning mode for each warning location, and can be set by the user from the plurality of warning locations. It is preferable to accept the selected warning location and set the selected warning location. If it does in this way, the warning location which the user selected from a plurality of warning locations which exist on the course displayed will be made into a candidate for setting, and an alarm mode can be set up for every warning location. Therefore, for example, a warning mode in which warnings are not performed only at unnecessary warning points in a section where warnings on the route are felt loud can be adopted.

  (5) The storage means stores, as information related to the warning location, simple information and detailed information related to the warning location in association with the location information of the warning location along with the location information of the warning location, The setting means displays the simple information indicating the warning part, receives the selection of the simple information from the user, and receives the selection of the simple information, the detailed information regarding the warning part corresponding to the simple information is displayed. It is good to display.

  Simple information refers to information having a smaller amount of information than detailed information. For example, the simple information may be an icon, a mark, or a character that represents the type of warning. On the other hand, the detailed information may be a sentence or a picture indicating the content of the warning.

  (6) The detailed information may be information including warning contents issued by the warning means. For example, when a liquid crystal display is used as the warning means, the details of warning displayed on the liquid crystal display may be included in the detailed information. In this way, it is possible to know in advance what kind of warning is given only by looking at the detailed information. Therefore, it is possible to easily determine whether or not the warning location should be changed, and the setting can be performed more easily. The detailed information may be displayed at a predetermined position such as the lower part of the screen, for example.

  (7) Further, the detailed information may be performed together with a drawing showing a relation with the position of the warning part. For drawing showing the relationship with the location of the warning location, for example, connecting the location of the warning location and the location for displaying detailed information with a line, or drawing a speech bubble from the location of the warning location and displaying detailed information in the speech bubble It is good to do. In this way, it is possible to easily grasp the correspondence between what kind of warning is given at which place.

  Note that the display based on the detailed information may be performed while the display based on the simple information remains, or the display based on the simple information and the display based on the detailed information may be switched. For example, in the case of a configuration including a touch panel for setting, when a touch on the display area of the simple information is detected, the display is switched to display of the detailed information, and when a touch on the display area of the detailed information is detected, the simple information is displayed. You may make it switch to the display of.

  The display mode may be set, for example, by displaying a selection branch of the display mode and selecting from the selection branch. In particular, the selection branch may be displayed in the detailed information display area. In this way, it can be easily understood which display mode is selected at each warning location.

  (8) After displaying the detailed information, the warning mode setting means ends the detailed display when there is no operation for changing the warning mode of information related to the warning location corresponding to the detailed information for a predetermined time, and the simplified information Return to the display.

  In this way, for example, if the user accidentally selects simple information in a different part from the warning part that the user wants to change, the user performs the change operation for a predetermined time after displaying the detailed information of that part. If not, the display returns to the original simple information display. Therefore, usability is improved.

  (9) The storage means stores, as information about the warning location, a warning type in association with the location information of the warning location along with the location information of the warning location, and the warning mode setting means The warning location may be displayed in a different display mode for each type. In this way, the warning location is displayed in a different display mode for each type of warning. Therefore, since the type of warning at the warning location is known at the time of the route search, it is possible to take action corresponding to the type of warning in advance by checking the type of warning and its location.

  In addition, as a display aspect of a warning location, it is good to set it as the icon, mark, and character which represent the classification of warning, for example. For example, as a display mode, the mark may be the same and the color may be different depending on the type.

  (10) Further, the warning mode setting means may set a warning mode for each type of warning. In this way, for example, when it is desired to set a warning mode in which all warning types are not warned, it is only necessary to set a warning mode for the warning type, and set a warning mode for each individual warning point. This eliminates the need for setting.

  (11) The route search means searches a plurality of the routes, the route display means displays a plurality of routes searched by the route search means, and further displays a plurality of routes displayed on the route display means. It is preferable to provide route selection means for selecting a route to be navigated from among the routes. In this way, it is possible to easily set, for example, a route with the fewest warning points from a plurality of routes as a navigation target.

  (12) In particular, it is preferable to include a route-specific warning target location number display means for performing display related to the number of warning locations of each route searched by the route search means. Thus, if the display regarding the number of warning points of each route is performed, it is possible to easily determine which route should be selected. In particular, the number of warning locations may be displayed for each type of warning. In this way, when there are types that the user particularly wants to avoid, it is possible to easily select a navigation target route by paying attention to the number of the types. For example, the start position setting unit may set the current position set by the position detection unit as the start position.

  (13) The start position setting unit may set the start position based on an input from a user, and the end position setting unit may set the end position based on an input from the user. If it does in this way, the warning aspect of the warning location in arbitrary sections can be set up. For example, it is possible to easily change the warning mode of a warning part that has been annoying due to a warning on a road that has traveled in the past.

  (14) The warning mode setting means may be set by storing the warning mode at the warning location in a nonvolatile storage device. In this way, even if the electronic device is turned off, the warning mode set by the user does not disappear, and it does not take time for resetting.

  1 and 2 show the configuration of a navigation apparatus according to a preferred embodiment of the present invention. The navigation device has a thin rectangular case body 30 installed on a dashboard of a vehicle. The case body 30 includes a display unit 5 on the front surface, a touch panel 21 that detects which part of the display unit 5 is touched on the display unit 5, and alarm lamps 6 on both sides of the front surface. Yes. An SD card memory slot 31 is provided on the side surface, and an SD memory card in which map data and the like are recorded can be inserted into the SD card memory slot 31. This navigation apparatus performs map data for performing such navigation using map data stored in the SD memory card. Further, a USB terminal 22 is provided on the side surface opposite to the SD card memory slot portion 31, and the software application can be upgraded by connecting to a personal computer. In addition to the navigation function, this navigation device also has a function as a radar detector that detects a vehicle speed measurement device and the like.

  FIG. 2 is a functional block diagram of the navigation device. The microwave receiver 4 is disposed inside the back surface of the case body 30, and the display unit 5, the alarm lamp 6, and the infrared communication device 7 are disposed on the front surface of the case body 30. A GPS receiver 8 is disposed inside the upper surface side of the case body 30. Further, the adapter jack 9 is disposed on one side surface of the case body 30, and the power switch 10 and the DC jack 11 are disposed on the other side surface. A speaker is also built in the case body 30. The infrared communication device 7 transmits / receives data to / from a communication device incorporating an infrared communication device such as a mobile phone 12. The adapter jack 9 is a terminal for connecting the memory card reader 13. By connecting the memory card reader 13 to the adapter jack 9, data stored in the memory card 14 attached to the memory card reader 13 can be taken in. More specifically, the data stored in the memory card 14 includes update information such as information on a new target (position information including longitude and latitude, type information, etc.), and the update information passes through the control unit 18. Thus, the data is stored (downloaded) in the database 19 built in the apparatus, and the data is updated. The database 19 can be realized by a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. The database 19 stores information related to a certain target at the time of shipment, and data on the target added after that is updated as described above. Data update can also be performed via the infrared communication device 7.

  The DC jack is for connecting a cigar plug cord (not shown), and is connected to a cigar socket of the vehicle via the cigar plug cord so that power can be supplied. Furthermore, the apparatus of the present embodiment includes a wireless receiver 15 and a remote control receiver 16. The wireless receiver 15 receives incoming radio waves having a predetermined frequency. The remote control receiver 16 performs data communication with a remote control (portable device: handset) 17 and performs various settings for the device.

  In addition, the control unit 18 performs a predetermined process based on information input from the various input devices (GPS receiver 8, microwave receiver 4, wireless receiver 15, touch panel 21, remote control receiver 16, etc.). Execute, and output a predetermined alarm / message using an output device (display unit 5, alarm lamp 6, speaker 20, etc.). Note that these basic configurations can be basically the same as the conventional ones.

  The functions of the navigation device of the present embodiment are realized by being stored in the EEPROM of the control unit 18 as a program executed by the computer included in the control unit 18 and executed by the computer included in the control unit 18.

The database 19 stores road network information for navigation. The control unit 18 can search for a route (route) from one position to another using this road network information. Further, the database 19 stores a telephone number database in which a telephone number is stored in association with the location information and name of the house, company, facility, etc. of the telephone number, and an address and positional information of the address in association with each other. Provide an address database. The database 19 stores location information of traffic monitoring points such as speed measuring devices together with their types.
The control unit 18 has a function of reading road network information around the current position from the database 19 and displaying a map around the current position on the display unit 5.

  In addition, when the current position detected by the GPS receiver 8 and the position of the traffic monitoring point stored in the database 19 approach a distance of 500 m or less, the control unit 18 cancels the traffic monitoring point described later. If not set, as shown in FIG. 3, a warning screen 70 is displayed on the display unit 5 so as to overlap the currently displayed screen. FIG. 3 shows a display example of a warning screen 70 when the distance between the current position and the LH system, which is a kind of speed measurement device, which is one of the traffic monitoring points, is 500 m when the map 50 is displayed. Is shown. Further, when the traffic monitoring point is not set to the cancel mode described later and is not set to the silent mode, a warning sound indicating the alarm type and distance such as “500 m ahead LH system” is output from the speaker 7. Perform output processing.

  The control unit 18 has a function of performing processing of a general navigation device. That is, a map around the current position is displayed on the display unit 5 at any time, and a destination setting button is displayed. The control unit 18 performs a destination setting process when the touch panel 21 detects that the position corresponding to the display position of the destination setting button is pressed. In the destination setting process, a destination setting menu is displayed on the display unit 5 to prompt the user to select a destination setting method. The destination setting menu includes a telephone number search button and an address search button that prompt the user to select a destination setting method. When the telephone number search button is pressed, a telephone number input screen is displayed, and position information corresponding to the input telephone number is acquired from the database 19. When the address search button is pressed, an address selection input screen is displayed, and position information corresponding to the input address is acquired from the database 19. Then, the acquired position information is set as the position information of the destination, and a recommended route from the current position to the destination is obtained based on the road network information stored in the database 19. As a method for calculating the recommended route, a known method such as a Dijkstra method can be used.

  Then, the control unit 18 displays the calculated recommended route together with the surrounding map. For example, as shown in FIG. 4, a route 53 from the current position 51 to the destination 52 is displayed as a recommended route in a predetermined color (for example, red). Further, the control unit 18 compares the position information on the route 53 with the position information of the traffic monitoring point stored in the database 19, and displays the position of the traffic monitoring point located on the route 53. For example, as shown in FIG. 4, a balloon is displayed from a position on the road, and the type of traffic monitoring point at that position stored in the database 19 is displayed in the balloon. For example, FIG. 4A is a display example of a warning point search screen, and shows an example in which traffic monitoring points 55a to 55f are displayed. The traffic monitoring point 55a displays the letter “N” indicating the N system in a balloon. The traffic monitoring points 55b, 55c, and 55e display characters “LH” indicating the LH system in a balloon. The traffic monitoring point 55d displays “loop” characters indicating a loop coil in a balloon. The traffic monitoring point 55f displays the letter “H” indicating the H system in a balloon. As described above, when the touch on the balloon position in the simplified display state in which characters are displayed in the balloon is detected by the touch panel 21, the simple display is switched to the detailed display as shown in FIG. . In the detailed display, the warning screen shown in FIG. 3 is displayed in a balloon. FIG. 5 shows a display example in which the simple display is switched to the detailed display when it is detected that the inside of the balloon of the traffic monitoring point 55b in FIG. 4A is touched. This initial state is referred to as a normal mode.

  Furthermore, as shown in FIG. 6, when the touch of the traffic monitoring point in the detailed display is detected in the normal mode, “silent” is displayed and the traffic monitoring point is switched to the silent mode. In the silent mode, as shown in FIG. 3, a warning is given by displaying on the display unit 5 when approaching a traffic monitoring point, but no voice warning is given. Further, as shown in FIG. 6, when the touch of the traffic monitoring point in the detailed display is further detected in the silent mode, “cancel” is displayed and the traffic monitoring point is switched to the cancel mode. The cancel mode is a mode in which neither a warning by display of FIG. 3 nor a warning by voice is performed. Further, when the touch of the traffic monitoring point in the detailed display is detected in the cancel mode, the mode is changed to the simple display and switched to the normal mode as shown in FIG. In the detailed display state, when the time is over after a predetermined display time (5 seconds), the mode set at the traffic monitoring point is maintained and the display is switched to the simple display. For example, if the traffic monitoring point is not touched for 5 seconds in the detailed display state in the cancel mode, the traffic monitoring point is switched to the simple display while being set in the cancel mode, assuming that the time is over. This 5 seconds may be changed by setting, or it is possible to enable / disable the time over, and when the time over is set to invalid, there is no touch in the detailed display. However, the detailed display may be maintained as it is without switching to the simple display.

  By performing the processing as described above, a warning part necessary for passing through the route 53 is displayed. Therefore, it is possible to know in advance a warning location when passing through the route 53. In this way, the warning mode of the displayed traffic monitoring point can be set based on the input from the user, and the set warning mode (normal mode for warning by sound and display or by light) A warning process is performed based on a silent mode in which only a warning is performed and a warning by sound is not performed, or a cancel mode in which a warning is not performed. Therefore, a warning in a warning mode desired by the user is issued, and dissatisfaction with the warning mode that the user has can be prevented or eliminated in advance.

  In addition, a traffic monitoring point selected by the user from among a plurality of traffic monitoring points existing on the route displayed on the display unit 5 is set as a setting target, and an alarm mode can be set for each traffic monitoring point. Therefore, for example, a warning mode in which warnings are not performed only at unnecessary warning points in a section where warnings on the route are felt loud can be adopted.

  In addition, since the simple information and the detailed information can be switched, the screen can be used effectively, and an easy-to-understand display can be performed. Further, since the detailed information is information including the warning contents displayed on the display unit 5 shown in FIG. 3, it is possible to know in advance what kind of warning is given when approaching the point. I understand. Therefore, it can be easily determined whether or not the traffic monitoring point is to change the warning mode, and the setting can be performed more easily.

  In addition, since a balloon is drawn from the position of the traffic monitoring point and detailed information is displayed in the balloon, it is possible to easily grasp the correspondence between what kind of warning is given at which place. .

  Further, as shown in FIG. 4A, a traffic monitoring point type designation unit 56 is displayed at the lower right of the display unit 5. The traffic monitoring point type designation unit 56 is a part that displays a button listing the types of traffic monitoring points existing on the route 53. In the example of FIG. 4A, the “N” type button 57a indicating the N system of the traffic monitoring point 55a, the “LH” type button 57b indicating the LH system of the traffic monitoring points 55b, 55c, and 55e, A “loop” type button 57c indicating the loop coil of the monitoring point 55d and an “H” type button 57d indicating the H system of the traffic monitoring point 55f are displayed. When the touch on the display unit of the type button is detected from the touch panel 21, the control unit 18 reversely displays the touched type button and simplifies the display mode of the traffic monitoring point corresponding to the touched type button. If it is being displayed, it is switched to detailed display, and if it is being displayed in detail, it is switched to simple display. FIG. 7 shows a display example when the “LH” type button 57b is touched in the display state of FIG. That is, the traffic monitoring points 55b, 55c, and 55e of “LH” are collectively changed from the simple display of FIG. 4A to the detailed display of the normal mode of FIG. Further, when the “LH” type button 57b is touched, the traffic monitoring points 55b, 55c, and 55e of “LH” are collectively changed to the silent mode and displayed as described with reference to FIG. Do. Further, when the “LH” type button 57b is touched, the traffic monitoring points 55b, 55c, and 55e of “LH” are collectively changed to the cancel mode and displayed as described with reference to FIG. Do. Further, when the “LH” type button 57b is touched, the traffic monitoring points 55b, 55c, and 55e of “LH” are set to the normal mode and are collectively changed to the simple display as described with reference to FIG. Display.

  In this way, if you want to set a warning mode that all types of traffic monitoring points do not warn, simply touch the type button for the type of traffic monitoring point and set the warning mode to cancel mode etc. There is no need to set a warning mode for each individual warning point, and setting work can be saved.

  Further, after the detailed information is displayed, if there is no touch on the traffic monitoring point corresponding to the detailed information for a predetermined time, the detailed display is terminated and the simplified information is displayed again. Even if you touch the simple information of another part different from the traffic monitoring point you want to return to the original simple information display if you do not perform any change operation for a predetermined time after displaying the detailed information of that part . Therefore, usability is improved.

  In addition, since the traffic monitoring points are simply displayed or displayed in detail in a display mode that indicates the type of each warning type, the type of warning at each traffic monitoring point can be known when the route is searched. Accordingly, it is possible to take a response corresponding to the type of warning in advance by looking at the type of warning and its location.

  The warning mode (normal mode, silent mode, cancel mode) at each traffic monitoring point may be stored in a nonvolatile storage device. In this way, even if the electronic device is turned off, the warning mode set by the user does not disappear, and it does not take time for resetting.

  In this embodiment, as shown in FIG. 3, the warning screen 70 is displayed at the center of the display unit 5. However, the present invention is not limited to this, and various modes can be adopted. For example, a display similar to the display shown at the traffic monitoring point 55b in FIG. 5 may be used as the warning screen. That is, the warning screen may be displayed in association with the position on the road by a balloon or the like.

  In addition to the route search, the navigation device has a function of specifying an arbitrary start point and end point on the map, and searching and displaying a plurality of recommended routes (routes) in the specified section. FIG. 8 is a diagram illustrating a display example when the control unit 18 detects a touch at the position of the end point 62 after detecting a touch at the position of the start point 61 on the map displayed on the display unit 5. It is. The control unit 18 searches for and displays a plurality of recommended routes from the start point 61 to the end point 62. In FIG. 8, two routes of a route 63a and a route 63b are searched and displayed. Then, balloons are displayed from above each route, and the travel time, travel distance, and number of warning points (number of traffic monitoring points) in the route are displayed inside the balloon, and the road network information and traffic monitoring points stored in the database 19 are displayed. It is calculated from the position information and displayed. That is, the travel distance is obtained by integrating the distance of the position information of the start point and end point of each road included in the route road network, and the travel time is the average value of the speed per hour output from the GPS receiver. The number of warning points is obtained by counting the number of traffic monitoring points existing on the route road network. In the display example of FIG. 8, the travel time 1 hour, the travel distance 22 km, and the warning point (number) 10 (location) are displayed for the route 63a. The route 63b is displayed with a travel time of 1.5 hours, a travel distance of 30 km, and a warning point (number) of 1 (location). The route 63a is displayed in red, and the route 63b is displayed in blue.

  When a touch on any one of the routes 63 is detected on this screen, a warning point search screen similar to the screen described with reference to FIG. Thereafter, the same setting as that shown in FIGS. 4 to 7 can be performed.

  Since the number of warning points for each route is displayed in this way, it is possible to easily determine which route should be selected. For example, it is possible to easily set a route having the least number of warning points from a plurality of routes as a navigation target. In addition, the route can be selected by comprehensively considering the travel time, the travel distance, and the number of warning points. Note that the number of warning locations may be displayed for each type of warning.
