Description

  The present invention relates to a control system that performs control related to an alarm for approaching an alarm target.

  2. Description of the Related Art Conventionally, there is known an alarm device that notifies an approach alarm when a previously stored alarm target position and a current position are in a predetermined approach state (for example, Patent Document 1). For example, when the distance between the alarm target position and the current position reaches 500 m, voice output such as “500 m ahead, it is the control area” is started. This is done by displaying characters, icons, etc.

JP 2010-160024 A

  However, it is necessary to pay attention to the vehicle and pedestrians ahead while driving, and such a screen cannot be watched. In addition, there are cases where such a brief warning sound is missed. However, if such alarm sound notification is repeatedly performed for a long time, for example, there is a problem that it is troublesome when the content of the alarm sound is already heard. Moreover, since the output of the warning sound is completed in a short time, there is a problem that it is difficult to continue the urgency.

  Therefore, an object of the present invention is to provide a control system and the like that can realize an approach alarm that makes it easier to understand the approach alarm by sound than in the past, is bothersome, and can maintain a sense of urgency.

  In order to achieve the above-described object, the control system according to the present invention includes (1) a sound alarm function for performing an approach to an alarm object by outputting an alarm sound, and a music alarm for performing an approach to the alarm object by reproducing a music. And a function.

  By doing so, it is possible to know the approach to the alarm target by “voice” and also to know that the access alarm is being performed by “reproduction of music”. Accordingly, it is possible to realize an approach warning that makes it easier to understand the approach warning by sound than in the past, is bothersome, and can maintain a sense of urgency.

The song may be a song that is particularly tense. Also, it should be a song that allows you to feel the approaching feeling from the sound. It is good to make the song that the driver can easily recognize that it is an approach warning.
(2) The music may be played back for a time longer than the output time of the alarm sound.

By doing in this way, the possibility that it is possible to know that an approach alarm is being performed by the reproduction of music increases. In addition, even if you miss a warning sound that ends in a short time, it is more likely that you will be able to hear a song that will be played for a longer time than the warning sound, and it is possible to recognize that you are in the proximity warning because the song is flowing Increases nature. Therefore, it is possible to realize an approach alert that makes it easier to understand the approach alert by sound than in the past, is bothersome, and can maintain a sense of urgency.
(3) The music may be reproduced until a time after the end of the output of the alarm sound.
In this way, even if the user has missed the warning sound, if the song can be heard, it can be known that the approach warning is being performed.

  The reproduction of the song may be started from a time point after the end point of the output of the alarm sound, may be started from a time point during the output of the alarm sound, or from the start time of the output of the alarm sound. It may be started, or may be started from a time before the start time of alarm sound output.

  (4) As the alarm sound, an alarm sound including contents relating to the type of the alarm target may be output, and the reproduction of the music may be started from a time point before the start time of the output of the alarm sound.

  By doing so, it is possible to know the approach to the alarm target by starting the reproduction of the music, and to listen carefully to the alarm sound made thereafter. Then, it is possible to grasp the detailed type of the alarm target from the content of the alarm sound heard with such attention.

For example, the reproduction of the music may be ended at a time before the start of the output of the alarm sound, may be ended at the start of the output of the alarm sound, or at a time when the alarm sound is being output. The process may be terminated, may be terminated at the end of the output of the alarm sound, or may be terminated at a time after the end of the output of the alarm sound.
(5) The music may be played back before and after an audio alarm including the output of the alarm audio.
By doing in this way, both a voice warning and a warning by music are made at the same time, and it becomes easier to understand the approach warning by sound than in the past.
For example, it is particularly preferable that the song is configured such that at least a part of the song functions as a voice alarm BGM.
(6) It is good to set it as the structure which adjusts so that the completion | finish time of reproduction | regeneration of the said music may become the time when the said warning object becomes a predetermined separation relationship.

  By doing in this way, possibility that the reproduction | regeneration of a music will be complete | finished will become high when a warning object becomes a predetermined separation relationship. Therefore, it can be recognized that the alarm target has a predetermined separation relationship when the reproduction of the music is completed.

The predetermined separation relationship may be, for example, a time when the current position can be regarded as having passed the position of the alarm target, or a time when the current position is not approaching the position of the alarm target.
(7) The control for adjusting the end of reproduction of the music to be the time when the alarm object is in a predetermined separation relation may be control for repeating a part of the music.

In this way, the reproduction of the music ends when a predetermined separation relationship is reached by repeating a part of the music. The song recording capacity can be reduced, and adjustments can be made without cost by simple control. As a part of the song, for example, a predetermined repeatable melody portion may be used.
(8) The music may include a chorus part, and may be configured to perform control so that the reproduction of the chorus part of the music and the output of the warning sound are performed.

  In this way, the rust portion can be heard at the time related to the output of the alarm sound. Therefore, by recognizing the presence of rust, it is possible to recognize the relationship with the alarm.

  For example, if the rust is played after the warning sound is output, the swaying of the rust portion of the song is related to the output of the warning sound. Can be recognized, and it is easy to continue the sense of urgency to approach. The chorus part is generally inside the song, not at the beginning. Therefore, the approach to the alarm target can be known in advance by reproducing the portion of the song leading to the chorus. In this state, when the reproduction of the song reaches the chorus, for example, it is possible to give a feeling that “the alarm target is finally approaching”. In addition, the rust and the alarm sound that informs the user of the approach to the alarm target are notified in association with each other. Accordingly, it is possible to realize an approach warning that makes it easier to understand the approach warning by sound than in the past, is bothersome, and can maintain a sense of urgency.

  For example, if the rust is played before the warning sound is output, for example, if the rust is played before the warning sound is output, it is predicted that the warning sound will flow after the rust is played. Because you can, you can watch out for the alarm sound when rust flows. As the time point at which the reproduction of the rust portion of the music and the output of the warning sound are related, for example, if the warning sound is reproduced during the reproduction of the rust, the effects of both can be obtained, which is most desirable.

  (9) The control to be performed at the time when the reproduction of the chorus part of the song and the output of the warning sound are related is the control to output the warning sound during the reproduction of the chorus part of the song It is good to do.

  In this way, since the warning sound is output during the reproduction of the chorus portion of the music, it is possible to suppress the alarm from being missed as compared with the conventional simple warning based on the voice.

  During playback, for example, the playback may be started or may be a while after starting playback. As the control for outputting the warning sound during the reproduction of the rust portion of the music, for example, it may be configured to determine the reproduction of the rust portion and output the warning sound.

  (10) The alarm sound is composed of a combination of a plurality of types of sound phrases, and the control to be performed at the time when the reproduction of the chorus portion of the song and the output of the alarm sound are related is performed by Among them, it is preferable that the alarm sound be output during reproduction of a predetermined type of phrase.

  In this way, a predetermined type of phrase in the alarm sound is emphasized by playing the chorus. Therefore, for example, it is possible to easily grasp a particularly important type of phrase in the alarm sound as compared with the conventional case.

  The predetermined type of phrase may be, for example, a phrase indicating the warning level of the alarm target, a phrase indicating the type of the alarm target, or a phrase indicating the degree of approach to the alarm target.

  (11) As a control to be performed at the time when the reproduction of the chorus portion of the music and the output of the warning sound are related, it is preferable to include a control for adjusting the start time of the music playback.

  In this way, the reproduction of the rust portion of the song and the output of the warning sound are performed with a simple configuration. For example, even if the playback state is not changed during playback of the music, the music is simply played back, and the playback of the rust portion of the music and the output of the warning sound are performed with a simple configuration.

  (12) The music includes a reproducible part in front of the chorus part, and the control is performed so that the reproduction of the chorus part of the music and the output of the warning sound are related. It may be configured to include a control for adjusting the number of times that the reproducible portion is repeatedly reproduced.

  In this way, the reproduction of the rust portion of the song and the output of the warning sound are performed with a simple configuration. For example, by adjusting the number of times of repeated playback without changing the playback speed or the like of the song, the playback of the chorus portion of the song and the output of the warning sound are performed.

  (13) The song includes a first song that can be repeatedly played without including a chorus portion, and a second song that includes a chorus portion, and at the start of the chorus portion of the second song, It may be configured to start outputting alarm sound.

  In this way, it is possible to easily suppress variations in the approach state with respect to the alarm target between the reproduction start time of the rust portion of the music and the output start time of the alarm sound. That is, it is possible to easily set the start time of alarm sound output when the state of approach to the alarm target is within a certain range.

  For example, the first song may be a song in which the end of the song and the start of the song are not recognized as discontinuous during repeated playback, and in particular, a song in which the end of the song and the start of the song are continuous during repeated playback. The song should be felt by the driver. The end of the first song and the end of the second song may be configured so that the end of the first song and the start of the second song are not recognized as discontinuous. It is good to set it as the structure of the music which a driver | operator feels with one music which the end part of music and the start part of the 2nd music continued.

  (14) The length of the second song ranges from 10 seconds to 30 seconds, and the second song has a rust start portion near the start of the song, and the end of the second song It may be configured to control so that the time point becomes a time point that is regarded as the passage of the alarm target.

In this way, rust reproduction starts from a point of time approximately 10 to 30 seconds before the point of time when the alarm object is considered to have passed. Further, it is possible to easily increase the possibility that the reproduction of the music is finished when it is considered that the alarm target has passed.
For example, the number of reproductions of the first song may be adjusted so that the reproduction of the song ends when it is considered to pass the alarm target, taking into account the length of the second song.

(15) A configuration in which information related to the moving speed is acquired at a time prior to the time when the warning sound is output, and control is performed to determine the number of repetitions of the first song based on the information related to the moving speed. It is good to do.
In this way, it is possible to easily increase the possibility that the reproduction of the music is finished when it is considered that the alarm target has passed.
For example, when the number of repetitions of the first song is 40 km / h, the number of repetitions may be twice the number of times when the speed is 80 km / h.

  (16) As the alarm sound, an alarm sound including the content related to the distance to the alarm target is output, and the time required from the start of reproduction to the end of reproduction of the second song and the time point when the alarm sound is output Further, it is preferable that the content related to the distance to the alarm target, which is the content of the alarm sound, is determined based on the information regarding the moving speed at the previous time point.

  The content related to the distance to the alarm target, which is the content of the alarm sound, is the movement speed before the time when the alarm sound is output and the time required from the start of playback of the second song to the end of playback. To be determined. Therefore, it is easy to make the information related to the distance that is the content of the alarm sound close to the actual distance, and at the time of the start of playback of the rust portion of the song and the start time of the output of the alarm sound, It is possible to easily suppress variations related to the approaching state. In particular, the time required from the start of playback of the second song to the end of playback may be a fixed time (fixed time).

(17) As the alarm sound, an alarm sound including the content related to the distance to the alarm target is output, and the length from the start point of the song to the end point of the song is constant, and the end point of the song It is good to make it control so that it becomes the time when it is considered that the above-mentioned alarm object passes.
In this way, it is possible to easily increase the possibility that the end point of the song will be a point in time that is regarded as the passage of the alarm target.
For example, the length from the start point of the song rust to the end point of the song may be a fixed fixed number of seconds of about 10 to 30 seconds.

(18) As the alarm sound, an alarm sound including the content related to the distance to the alarm target is output, and the approach distance from the alarm target at the start of the rust of the song is determined from the time when the alarm sound is output. It is good to set it as the structure which estimates at the previous time and changes the content regarding the distance to the said warning object of the said warning sound according to the said estimated distance.
If it does in this way, the content regarding the distance close | similar to the distance with an actual warning object will be output as a warning sound.

  (19) As the alarm sound, an alarm sound including the content related to the distance to the alarm target is output, and the content related to the distance to the alarm target that is the content of the alarm sound is determined to output the alarm sound. It is preferable to adopt a configuration based on the previous movement state.

  If it does in this way, the accuracy of the content regarding the distance to the said warning object which is the content of warning sound can be raised. Accordingly, it is possible to prevent a difference between the content of the alarm sound and the state of approach to the actual alarm target from causing a sense of incongruity or miscommunication as having passed through the actual alarm target. For example, speed may be used as the moving state.

  (20) The content related to the distance to the alarm target may include a plurality of levels corresponding to the distance, and the content of any level may be output as a warning sound according to the distance.

In this way, it is possible to easily grasp how far the distance is. For example, the distance is set to three levels of 400m, 500m, and 600m, and the alarm sound selected from the three patterns of "400m to the alarm target", "500m to the alarm target", and "600m to the alarm target" It is good to output.
(21) It is good to set it as the structure which outputs at least any one of time or distance until the present position reaches the said warning object as said warning sound.

  In this way, it is possible to reliably know how long it will take to reach the alarm target, and it is also possible to know that the approach alarm is being performed by an alarm by the music alarm function. Accordingly, it is possible to realize an approach warning that makes it easier to understand the approach warning by sound than in the past, is bothersome, and can maintain a sense of urgency.

  (22) As an approach to the alarm target, when a pre-stored position of the alarm target and the current position are in a predetermined approach relationship, a radio wave of a frequency emitted by the alarm target is received, It may be configured to include a case where the reception state is a predetermined reception state.

For example, when the alarm target is a microwave radar for speed control, it may be assumed that a predetermined reception state is reached when radio waves of the frequency of the microwave radar are received and the signal intensity is a predetermined value or more. Further, it may be set as a case where a predetermined reception state is reached when a radio wave of a specific frequency emitted by an emergency vehicle is received and the signal intensity is a predetermined value or more.
(23) A plurality of the alarm sounds may be provided according to the type of the alarm target, and a function of reproducing a music for alarm according to the type of the alarm target that is approaching may be provided.

In this way, it is possible to know which type of alarm target is approaching by listening to the audio, and by listening to the song, it is possible to approach which type of alarm target depending on the type of the song. You can know if you are. For example, even if an alarm sound is missed, it is possible to know which alarm object is approaching according to the type of music. Therefore, the approach warning by sound is easier to understand and less troublesome than before.
(24) The volume of reproduction of the music may be configured to be smaller than the volume of output of the alarm sound.
In this way, it is possible to prevent the content of the alarm sound from becoming difficult to hear due to the reproduction of the music, and it is possible to know the alarm content more reliably.

(25) It is good to set it as the structure which performs the control which sets separately the volume of the output of the said warning sound, and the volume of reproduction | regeneration of the said music. For example, it is good to set it as the structure which sets both volume separately according to operation from a user.
(26) It is good to comprise as a program for making a computer implement | achieve the function of the control system in any one of (1)-(25).

  ADVANTAGE OF THE INVENTION According to this invention, the control system etc. which can implement | achieve the approach alarm which becomes easier to understand the approach alert by a sound compared with the past, without bothering, and being able to continue a tense feeling can be provided.

This position history is recorded in the NMEA format, for example.

  The standby screen display function is a function for displaying a predetermined standby screen on the display unit 5. FIG. 3A shows an example of a standby screen. Here, the speed, latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 13 are shown.

  As shown in FIG. 3B, the map display function is a function for accessing the database 19 based on the current position detected by the GPS receiver 13, and reading and displaying the map data stored therein. In addition, the map display function searches for an alarm target around the current position based on position information stored in the database 19, and indicates the alarm target at a corresponding position on the map when an alarm target exists around the current position. A function of displaying information (such as the target icon 112) in an overlapping manner is also provided. The specific display mode is as follows.

  The control unit 18 displays a map in the main display region R1 on almost the entire surface of the display unit 5 so that the traveling direction of the vehicle is always directed upward. The control unit 18 displays the map so that the lower center of the main display region R1 is the current vehicle position, and displays the vehicle icon 111 at the position.

  The control unit 18 displays status information in the status area R2 set above the main display area R1. Status information displayed in the status area R2 includes, in order from the left, the current time 121 (“15:10” in the figure), the GPS radio wave reception level display icon 122 (three straight lines of different lengths in the figure in parallel). Standing maximum reception level), parking prohibited area icon 123 (displayed when parking is in the highest priority area, parking priority area), and reception sensitivity mode display icon 124 (in the figure, “SE” having the highest sensitivity) indicating the reception sensitivity of the radar. ), Vehicle speed 125 (“30 km / h” in the figure), and azimuth magnetic needle 126. The status area R2 is a transparent area and is arranged using a layer above the layer of the main display area R1. As a result, even in the status area R2, the map located on the lower side can be visually recognized at the place where the status information is not displayed.

  The control unit 18 displays the current scale information (scale) in the scale display region R3 set on the left side of the main display region R1. The scale displays the distance from the vehicle position to the middle position in the vertical direction of the main area R1 ("500" in the figure) and the distance to the upper position ("1000" in the figure). To do. The unit is “m”. When detecting that the main display area R1 has been touched twice in succession, the control unit 18 displays a map scale change button at a predetermined position (position along the scale display area R3) in the main display area R1 (illustrated). (Omitted), the map scale is changed according to the touch on the map scale change button. That is, the control unit 18 changes the scale of the map displayed in the main display area R1 according to the changed scale of the map scale, and also changes the scale information displayed in the scale display area R3.

  While executing the standby screen display function as shown in FIG. 3A, the control unit 18 that has detected a single touch on the display unit 5 displays a menu screen. The control unit 18 that has detected that the screen switching button prepared in the menu screen has been touched switches to the map display function as shown in FIG. Similarly, the control unit 18 that has detected a single touch on the display unit 5 during execution of the map display function displays a menu screen.

A process for realizing each function such as an alarm function is executed, and when the process of the function is completed, the process returns to the process of the original standby function. The priority of each function is set in the order of radar wave warning function, radio alarm function, and GPS alarm function from the highest.

  The GPS alarm function is a process executed at predetermined time intervals (1 second intervals) by an event from a timer included in the control unit 18 and detected by the latitude and longitude of the alarm target stored in the database 19 and the GPS receiver 13. When the distance between the two is obtained from the latitude and longitude of the current position and the obtained distance becomes a predetermined approach distance, a GPS alarm display 130 (alarm target) as an alarm screen as shown in FIG. ) (Schematic diagram, remaining distance, etc.) and an approach warning sound indicating the fact is output from the speaker 16.

Such alarms include snoozing driving accident points, radars, speed limit switching points, control areas, inspection areas, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignorance suppression systems, police stations, frequent accidents Area, frequent on-board areas, sudden / continuous curve (highway), branch / merge point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), highway Oasis (highway), smart interchange (highway), PA / SA petrol station (highway), tunnel (highway), highway radio reception area (highway), prefectural border notice, roadside station, viewpoint parking, etc. The type information of these targets, the latitude / longitude information indicating the position, and the display unit 5 Stored in the database 19 in association with the formulas drawings or photos and audio data.

  FIG. 4B shows a display example of the radar wave warning function. This radar wave warning function is used when a signal corresponding to microwaves in a frequency band emitted from a velocity measuring device (mobile radar or the like (hereinafter simply referred to as “radar”)) is detected by the microwave receiver 14. This is an alarm function that displays a GPS alarm display 131 as an alarm screen on the display unit 5 and outputs an alarm sound from the speaker 20. For example, when a microwave in the microwave frequency band emitted by the radar is detected by the microwave receiver 4, a schematic diagram or a photograph of the radar stored in the database 19 is displayed as shown in FIG. The voice data stored in the database 19 is read out on the unit 5 as an alarm screen, and a voice “Radar. Speed attention” is output from the speaker 16. The displayed distance may be a distance estimated from the electric field strength, for example.

  The wireless alarm function is a function for issuing an alarm so that the wireless receiver 15 does not interfere with traveling or the like when a radio wave emitted by an emergency vehicle or the like is received. In the radio alarm function, the control radio, car radio, digital radio, special radio, police radio, police phone, police activity radio, wrecker radio, heli tele radio, fire helicopter radio, fire fight radio, emergency radio, expressway radio , Scan the frequency of the security radio, etc., and when the radio is received at the scanned frequency, a schematic diagram showing that the radio corresponding to the frequency stored in the database 19 for each radio type is received as an alarm screen While displaying on the display part 5, the audio | voice data memorize | stored for every radio | wireless classification in the database 19 are read, and the alarm sound which shows the radio | wireless classification from the speaker 16 is output. For example, when a control radio is received, a voice is output like “control radio. Speed attention”.

  Hereinafter, alarm processing for realizing the BGM alarm function which is a feature of the present invention will be described. The BGM alarm function is a function that emits an alarm sound during the reproduction of a song, and the control unit 18 executes a program so as to emit an alarm sound at the chorus portion of the song. The radar detector of the present embodiment includes a normal alarm mode in which no BGM alarm is performed and a character alarm mode in which a BGM alarm is performed, and it is set in which mode the operation is switched by user setting. In the normal alarm mode, when the alarm object is approached, an alarm having a schematic diagram as shown in FIG. 4A is performed. On the other hand, in the character alarm mode, as shown in FIG. In this mode, a BGM alarm is displayed.

  As described above, the animation display is one of notification modes in the GPS alarm function, and is performed in place of the above-described schematic diagram or actual photograph displayed on the display unit. The warning based on the schematic diagram or the like or the warning based on the animation display of the character is performed based on the user setting as described above. This user setting is performed based on the touch position of the menu screen when the control unit 18 that detects that the main display region R1 is touched once displays the menu screen. Furthermore, various conditions are set for this user setting, such as whether a character is used or whether the display is always displayed even when the alarm target is not present. These condition settings are also determined by touching a menu screen (not shown).

  Here, it is assumed that an alarm using a character imitating a human (character 300) is selected by user setting, and that the character is also set to always display. The character 300 in this embodiment is a young woman, so that it is easy to get close. When a young woman gives an alarm notification or the like, the user can expect the effect of listening safely to the alarm content and driving safely.

  As shown in FIG. 5, the control unit 18 displays the character 300 at the lower right position in the main display region R <b> 1 of the display unit 5. The layer displaying the character 300 is on the layer displaying the map, and the character 300 is synthesized and displayed on the map.

  The display mode of the character 300 includes a normal mode in which the alarm target is not present around as shown in FIG. 6A, and an emergency in which an alarm target is present in the surrounding as shown in FIG. 6B. There is an emergency mode to display. In the normal mode, the costume to be worn is normal clothes, the appearance is the same as a normal human, and the eye color is blue. In the normal mode, a character is displayed, for example, at the same position as the character display position in FIG. 5 with the costume shown in FIG. 6A on the map display as shown in FIG. 3B. On the other hand, in the emergency mode, the costume to be worn is fighting clothes, the appearance is an ear-shaped antenna that seems to receive radar waves and radio waves, and the eye color is red. When the approaching relationship between the current position and the alarm target satisfies the first condition, the first animation for changing the character from the state of FIG. 6 (a) in the normal mode to the state of FIG. 6 (b) in the emergency mode is performed. . In addition, the second animation is performed when the approach condition between the current position and the alarm target satisfies a second condition that is an approach relation closer to the first condition.

  During the normal mode and after the first animation, which is a distance that is approaching but not approaching in the emergency mode, until the second animation is completed, the character 300 is displayed with the vehicle icon 111 or a predetermined value. Is displayed in an area not covered by the target icon 112 indicating the alarm target (see, for example, FIG. 5). For example, since the vehicle icon 111 is displayed at the lower center of the main display region R1, the region that does not cover the vehicle icon 111 and the target icon 112 is less than half of one side (right side in this example). For example, if the target icon 112 is located on the right side when the vehicle icon 111 is displayed in the lower center and is hidden under the character 300 as it is, the control unit 18 displays the entire map shifted by a predetermined distance to the left. To do. Since the vehicle icon 111 and the target icon 112 are not hidden by the character 300, the user recognizes the positional relationship between the vehicle icon 111 and the target icon 112 even when the character 300 is displayed, and the alarm target is currently running. You can check if it exists on the road.

  The second animation gradually expands from the state (the state of FIG. 5) in which the emergency mode character 300 is displayed in a region not covered by the vehicle icon 111 or the target icon 112 indicating a predetermined alarm target, as shown in FIG. This is an animation that changes a circular focus to a state in which a circular focus is superimposed on a map. At this time, the position of the map is controlled so that the alarm target icon (target icon 112) is positioned at the center of the focus circle shown in FIG. 7, and the screen as shown in FIG. 7 is superimposed on the map. To do. And the display which overlapped the map and the screen of FIG. 7 continues until the present position reaches the passing position of the alarm target. Thus, by enlarging the character and showing the focus, the driver can recognize that the state is very close to the alarm target.

  When the current position reaches the alarm passing position, a third animation is displayed. The third animation is an area where the character 300 is not in the vehicle icon 111 or the target icon 112 indicating a predetermined alarm object in the normal mode state (the costume state in FIG. 6A) from the state of FIG. This is an animation for returning to the normal mode displayed on the screen. Thereafter, the normal mode is displayed until the approaching relationship between the current position and another alarm target becomes the first condition.

  The BGM alarm is performed in association with such a character action. Specific processing of the control unit 18 will be described with reference to FIGS. FIG. 9 is a diagram showing a continuation of the table of FIG. 8 (it is not shown in a single figure, but is only divided into two figures). 8 and 9 (the part indicated by (a) in FIG. 8), as shown in the upper part of the table, it is assumed that 90 km / h, that is, 25 m per second is advanced. It is a figure which shows the reproduction | regeneration state of a music. On the other hand, the tables on the right side of FIG. 8 and FIG. 9 (the part indicated by (b) in FIG. 8), as shown in the upper part, move at a speed of 100 km / h, ie, about 27.8 m per second. It is a figure which shows the reproduction | regeneration state of the music on the assumption. The BGM alarm according to the present embodiment is an alarm notifying that an approach to an alarm target installed on a highway is in progress.

  In the table of 90 km / h and the table of 100 km / h, the position indicated as “pass” in the table is the position of the alarm target, and the position of the alarm target as it goes downward from the table. The position on the near side of the alarm target that is far from is shown. The “Song playback distance” column indicates the distance from the alarm target. These tables show “actual distance”, “alarm”, “total remaining music seconds”, “music playback distance”, “unit music seconds”, and “music part number” from the left, respectively.

  The column “actual distance” indicates the current position detected by the GPS receiver 8 and the position and distance of the alarm target stored in the database 19. The column “alarm” indicates the outline of the audio alarm. The alarm is a 2 km alarm that is the first audio alarm, a 1 km alarm that is the second audio alarm, and a several hundred meter alarm that is the third audio alarm (400 meter alarm, 500 meter alarm, 600 meter alarm Any one) 3 times. It should be noted that the description of “rust portion” in the table indicates that playback of the rust portion of song 2 starts at the start of several hundred meter alarm (the space described on the right side of “400 meter alarm” is It ’s just listed on the next line for convenience.) The “total remaining song seconds” column is used to play a song from the “pass” position when unit songs such as “song 1” and “song 2” are combined and played as shown in the “song part number” column. Shows the number of seconds required. “Song playback distance” indicates the distance from the “pass” position when the current position moves at the assumed speed. “Unit song seconds” indicates the number of seconds required for reproduction of a piece of music combining unit songs. As unit music, PCM data of music 1 and music 2 are stored on the EEPROM, and the control unit 18 controls the reproduction order of the PCM data to reproduce the music. “Song part number” is a column indicating which unit music is to be reproduced. The song 1 is 15 seconds, the song 2 is 19 seconds, and the last piece of the song 1 and the first part of the song 1 are configured so that each unit song can be heard so as to have continuity. Therefore, even if the music 1 is repeatedly reproduced, it is recognized as one music. The song is a song with a sense of urgency, and is a song that the driver can easily recognize as an approach warning. In addition, each unit music is configured so that the last part of the music 1 and the first part of the music 2 can be heard so as to have continuity. Therefore, song 1 and song 2 are recognized as one song. Therefore, one continuous song of the repeat of the song 1 and the song 2 is formed, and the driver recognizes that the song is a single song composed of the repeated portion of the song 1 and the portion of the song 2. The tune 1 has no rust portion, and the tune 2 is configured such that the rust of the song starts from the head portion (the playback start portion of the tune 2). In the column of “unit music seconds”, the continuous parts of music 1 and music 2 are values that are regarded as unit music as a unit.

  For example, if it is assumed that the vehicle is traveling at a constant speed of 90 km / h, as shown in the left table of FIGS. 8 and 9, Song 1 is played 5 times from 2325 m before (93 seconds before) the target. By configuring the song so that it is repeatedly reproduced and then the song 2 is reproduced once, the reproduction of the song is completed at the passing position. On the other hand, if it is assumed that the vehicle is traveling at a constant speed of 100 km / h, as shown in the tables on the right side of FIGS. 8 and 9, tune 1 is played 4 times before 2166 m before the target (from 78 seconds before). By configuring the song so that it is repeatedly reproduced and then the song 2 is reproduced once, the reproduction of the song is completed at the passing position. Thus, by changing the number of repetitions of the tune 1 according to the speed, the position of the tune can be made as close as possible to the passing position of the target. Actually, there will be a discrepancy between the assumed music playback distance and the actual distance due to fluctuations in travel speed. In the following manner,

  First, as shown at the bottom of each table in FIG. 9, when the actual distance reaches 2400 m, the reproduction of the music 1 is started and the first animation described above is performed. The time from the start to the end of playback of the first animation is 15 seconds, which is the same as the number of seconds of song 1. When the first animation ends, that is, when playback of song 1 ends (when 15 seconds have elapsed). A 2-kilometer alarm, the first audio alarm, is performed. That is, this 2 km alarm is not performed when the distance (actual distance) between the current position obtained from the GPS receiver 8 and the position of the alarm object reaches 2000 m, but the actual distance reaches 2400 m and 1 is started when 15 seconds have elapsed after that. Therefore, the actual distance and the distance that is the content of the alarm may deviate. However, if the vehicle travels at a speed of 120 km / h for 1 minute, it is 2 km. At the time of the 2 km alarm, there is still time to reach the alarm target that is the target. Therefore, it is not necessary to strictly match the actual distance and the distance of the alarm content, but since the 2 km alarm is made in conjunction with the reproduction of music and animation, the driver's attention can be easily obtained.

  Then, the music piece 1 is reproduced repeatedly so that the actual distance between the current position obtained by the GPS receiver 8 and the position of the alarm target (target) reaches 1 km and is reproduced once. This repeated reproduction is a process of starting reproduction from the beginning of the song 1 again after the reproduction to the end of the song 1 is completed. When the one-time reproduction of the song 1 after the actual distance reaches 1 km is completed, the reproduction from the beginning of the song 2 is started. When the reproduction of the song 2 is completed to the end, the reproduction of all the songs is finished. For example, as shown in the column of the song part number in the left table of FIGS. 8 and 9, assuming that the vehicle is traveling at a constant speed of 90 km / h, the actual distance has reached 1 km until it is played once. As a result of repeated reproduction, the music piece 1 is reproduced five times in total, and then the music piece 2 is reproduced. On the other hand, as shown in the column of the song part number in the right table of FIGS. 8 and 9, assuming that the vehicle is traveling at a constant speed of 100 km / h, until the actual distance reaches 1 km, it is played once. As a result of repeated reproduction, the music piece 1 is reproduced four times in total, and then the music piece 2 is reproduced.

  Then, when the actual distance reaches 1 km, a 1-kilometer alarm, which is the second audio alarm, is performed. This 1-kilometer alarm is performed by simultaneously reproducing the alarm sound “1 km ahead, target. Attention!” On the music 1 being reproduced and outputting it from the speaker 16. Since this distance is directly based on the actual distance unlike the 2 km alarm, the driver can know the distance to the correct alarm target. For example, if the speed is 120 km / h to 80 km / h, it is possible to grasp the exact distance from the alarm target about 30 seconds to 45 seconds before reaching the alarm target.

  On the condition that the reproduction of the music piece 2 is started, an alarm for several hundred meters, which is the third audio alarm, is performed. Prior to this, when the actual distance reaches 1 km, processing for determining whether to perform a 400-meter alarm, a 500-meter alarm, or a 600-meter alarm in this several hundred meter alarm is performed. The 400-meter alarm is a process of reproducing the alarm sound “400 m ahead, target, attention!” And outputting it from the speaker 16, and the 500-meter alarm reproduces the alarm sound “500 m ahead, target, attention!”. The 500 meter alarm is a process of reproducing the alarm sound “500 m ahead, target, attention!” And outputting from the speaker 16.

The process of determining whether to perform a 400-meter alarm, a 500-meter alarm, or a 600-meter alarm in a several hundred meter alarm is the time required for the actual distance to reach 1 km from 2400 m, and the distance between them is 1400 m Thus, the average speed during this period is obtained, the distance required to play the music piece 2 is calculated at that speed, and which alarm is to be determined according to the range to which this distance belongs. If the calculated distance required to play song 2 is less than 500 m, a 400-meter alarm is issued, if it is 500 m or more and less than 650 m, a 500-m alarm is given, and if it is 650 m or more, a 600-m alarm is decided. To do. Then, at the same time as the reproduction of the music 2 is started, the determined alarm of several hundred meters is given. For example, when the calculated average speed is 90 km / h (25 m / s), the distance required to reproduce the song 2 is 25 * 19 = 475 m as shown in the song reproduction distance column in the left table of FIG. . Therefore, the determination process corresponds to a case where the distance is less than 500 m, and a 400-meter alarm is issued when the reproduction of the song 2 is started. For example, when the calculated average speed is 100 km / h (27.8 m / s), as shown in the music playback distance column in the left table of FIG. = About 528 m. Accordingly, the determination process corresponds to a case where the distance is 500 m or more and less than 650 m, and a 500-meter alarm is issued when the reproduction of the music piece 2 is started. For example, when the calculated average speed is 130 km / h (36.1 m / s), the distance required to play the music piece 2 is 36.1 * 19 = about 686 m. Therefore, the determination process corresponds to a case of 650 m or more, and a 600-meter alarm is issued when the reproduction of the song 2 is started.
Then, when the reproduction of the song 2 is completed, a process of outputting a voice “passing” from the speaker 16 is performed.
Also, it should be a song that allows you to feel the approaching feeling from the sound.

As described above, the radar detector includes the voice alarm function that performs the approach to the alarm target by outputting the alarm sound, and the music alarm function that performs the approach to the alarm target by reproducing the music. Therefore, it is possible to know the approach to the alarm target by “voice”, and it is possible to know that the access alarm is being performed by “reproduction of music”. Accordingly, it is possible to realize an approach warning that makes it easier to understand the approach warning by sound than in the past, is bothersome, and can maintain a sense of urgency.
Since the song is particularly a song with a sense of urgency, when the song is played, the driver can easily grasp that the driver is in a state of caution.

  The music is played back for a time longer than the output time of the alarm sound. Therefore, the possibility that it is possible to know that the approach alarm is being performed by reproducing the music increases. For example, in the above-described example, the music is played for over 1 minute. Even if you miss a warning sound that ends in a short time, it is more likely that you will be able to hear a song that will be played for a longer time than the warning sound, and you may be able to recognize that you are in the proximity warning because the song is flowing. Get higher. Therefore, it is possible to realize an approach alert that makes it easier to understand the approach alert by sound than in the past, is bothersome, and can maintain a sense of urgency.

  The music is played back until a time after the end of the alarm sound output. Therefore, even if you miss the warning voice, you can know that the approach warning is in progress if you can hear the song.

  In this embodiment, the music is played back before and after the voice alarm and continuously during the voice alarm, but the music is played back, for example, after the end of the warning voice output. It may be started from a later time, may be started from the time when the alarm sound is being output, may be started from the start time of the output of the alarm sound, or may be started from the start time of the output of the alarm sound. You may start from a previous time.

  As the alarm sound, an alarm sound including contents related to the type of the alarm target may be further output, and the reproduction of the music may be configured to start from a time point before the start of the alarm sound output. For example, the part “target” in the alarm sound described above may be changed to the type of audio phrase and reproduced according to the type stored in the database 19 together with the target alarm target position. Good. For example, an alarm sound including content related to the type of alarm target is output, such as “400m ahead, control area. Caution!”. By doing so, it is possible to know the approach to the alarm target by starting the reproduction of the music, and to listen carefully to the alarm sound made thereafter. Then, it is possible to grasp the detailed type of the alarm target from the content of the alarm sound heard with such attention.

  For example, the reproduction of the music may be ended at a time before the start of the output of the alarm sound, may be ended at the start of the output of the alarm sound, or at a time when the alarm sound is being output. The process may be terminated, may be terminated at the end of the output of the alarm sound, or may be terminated at a time after the end of the output of the alarm sound.

  The music may be played back before and after the voice alarm including the output of the alarm voice as in this embodiment. By doing so, both a voice warning and a music warning are made at the same time, making it easier to understand the approach warning by sound than in the past. For example, it is particularly preferable that the song is configured such that at least a part of the song functions as a voice alarm BGM.

  In the present embodiment, the music piece 1 is repeatedly played back so that it is played once after the actual distance between the current position obtained by the GPS receiver 8 and the position of the alarm target (target) reaches 1 km. When the reproduction of the music piece 1 after the actual distance reaches 1 km is completed, the reproduction from the head of the music piece 2 is started. When the reproduction of the song 2 is completed to the end, the reproduction of the song is finished. As described above, the control is performed so that the end point of the reproduction of the music is adjusted so as to be the time point when the alarm target is in a predetermined separation relation. Therefore, there is a high possibility that the reproduction of the music is finished when the alarm target becomes a predetermined separation relationship. Therefore, it can be recognized that the alarm target has a predetermined separation relationship when the reproduction of the music is completed.

  The predetermined separation relationship may be, for example, a time when the current position can be regarded as having passed the position of the alarm target, or a time when the current position is not approaching the position of the alarm target. For example, a range in which the distance between the alarm target position and the current position is within several tens of meters may be set as the predetermined separation relationship.

  The control for adjusting the music playback end time to be the time when the alarm object is in a predetermined separation relation is the control for repeatedly playing the music 1 that is a part of the music. Therefore, the reproduction of the music (the reproduction of the music 2) is completed when the predetermined music object 1 is separated from the alarm target by repeating the music 1. Therefore, the recording capacity of the music can be reduced, and adjustment can be performed without cost by simple control. As a part of the song, for example, a predetermined repeatable melody portion may be used. For example, the tune 1 may be a predetermined repeatable melody portion.

  The song has a chorus portion from the beginning of the song 2, and is configured to perform control so that the reproduction of the chorus portion of the song and the output of the alarm sound are performed. For this reason, the rust portion can be heard at a time related to the output of the alarm sound. Therefore, by recognizing the presence of rust, it is possible to recognize the relationship with the alarm. In the present embodiment, the output of the alarm sound is started simultaneously with the reproduction of the first chorus part of the music 2 as the time point at which the reproduction of the chorus part of the song is related to the output of the alarm sound. If the rust is reproduced after the sound is output, for example, it can be recognized that the approaching relationship alerted by the alarm sound is continuing, and it is easy to continue the sense of urgency to approach. The chorus part is generally inside the song, not at the beginning. Also in this embodiment, the chorus part starts from the beginning of the song 2 which is the middle of the song consisting of the repetition of the song 1 and the song 2. Therefore, it is possible to know the approach to the alarm target in advance by reproducing the portion of the song 1 until the chorus is reached. When the song playback reaches the chorus of the song 2 in this state, for example, “Now the alarm subject is near. It can give a sense of "I haven't become". Then, the rust and the alarm sound that informs the user of the approach to the alarm target are notified in association with each other. Accordingly, it is possible to realize an approach warning that makes it easier to understand the approach warning by sound than in the past, is bothersome, and can maintain a sense of urgency.

  For example, if the rust is played before the warning sound is output, for example, if the rust is played before the warning sound is output, it is predicted that the warning sound will flow after the rust is played. Because you can, you can watch out for the alarm sound when rust flows. For example, if the warning sound is reproduced during the reproduction of the rust as in the above-described embodiment, the effect of both can be obtained as the time point at which the reproduction of the rust portion of the song is related to the output of the warning sound. Most desirable.

  The control to be performed at the time when the reproduction of the chorus part of the song and the output of the alarm sound are performed is the control for outputting the alarm sound during the reproduction of the chorus part of the song. For this reason, an alarm sound is output during the reproduction of the rust portion of the song, so that the alarm can be prevented from being missed as compared with a conventional simple sound alarm.

  During playback, for example, the playback may be started, or may be configured after a while from the start of playback. The control for outputting the warning sound during reproduction of the rust portion of the song may be configured to output the warning sound by determining the reproduction of the rust portion, for example.

  The alarm sound may be composed of a combination of a plurality of types of sound phrases. And, as a control to be performed at the time when the reproduction of the rust portion of the song and the output of the alarm sound are related, a control for outputting the alarm sound during the reproduction of a predetermined type phrase in the alarm sound; Good. For example, when outputting an alarm sound including the type of the alarm target described above, the phrase “400m ahead, control area. Caution!” May be provided as one PCM data and played back. It is composed of a plurality of phrases “400m ahead” that is the distance, “control area” that is the type of alarm target, and “attention!” That is the alert sound, and a combination of these phrases is played back to perform an audio alarm. May be. For example, by controlling the playback start time of the song 2 to be the playback start time of the phrase “attention!”, It is possible to emphasize the phrase of the type of alerting “attention!”. In this way, a predetermined type of phrase in the alarm sound is emphasized by playing the chorus. Therefore, for example, it is possible to easily grasp a particularly important type of phrase in the alarm sound as compared with the conventional case. The predetermined type of phrase may be, for example, a phrase indicating the attention level of the alarm target, a phrase indicating the type of the alarm target, or a phrase indicating the degree of approach to the alarm target. It is good to be able to set whether to match the type of phrase and chorus playback.

  The present embodiment is configured to include control for adjusting the start point of the reproduction of the music piece 2 as the control to be performed at the time point when the reproduction of the chorus portion of the music piece and the output of the alarm sound are related. Therefore, as described above, the reproduction of the rust portion of the song and the output of the warning sound are performed with a simple configuration. For example, even if the playback state is not changed during playback of the music, the music is simply played back, and the playback of the rust portion of the music and the output of the warning sound are performed with a simple configuration.

  In the present embodiment, the tune has a reproducible portion before the rust portion, and the control is performed so that the rust portion of the tune and the output of the warning sound are related to each other. This is a configuration including a control for adjusting the number of times of replaying the tune 1 that is a reproducible portion. With such a simple configuration, the reproduction of the rust portion of the song and the output of the warning sound are performed at a time point related to each other. For example, even if the number of repeated playbacks is adjusted without changing the playback speed or the like of the song, the playback of the chorus portion of the song and the output of the alarm sound are performed.

  The tune includes a tune 1 that is a first reproducible song that does not include a rust portion, and a tune 2 that is a second song that includes the rust portion, and the start of the rust portion of the second song It is configured to start outputting alarm sound at the time. Therefore, it is possible to easily suppress variations in the approach state to the alarm target between the playback start time of the rust portion of the song and the output start time of the alarm sound. That is, it is possible to easily set the start time of alarm sound output when the state of approach to the alarm target is within a certain range.

  The first song, song 1, is a song in which the end of the song and the beginning of the song are not recognized as being discontinuous during repeated playback, and the end of the song and the beginning of the song are repeated during repeated playback. The song is felt by the driver. In addition, the end of the first song and the end of the second song are not recognized as being discontinuous between the end of the song 1 that is the first song and the start of the song 2 that is the second song. The ending portion of the tune 1 that is the first tune and the start portion of the tune 2 that is the second tune are one tune and a tune that can be felt by the driver.

  The length of the second song, song 2, is 19 seconds, but it is particularly preferable that it be in the range of 10 seconds to 30 seconds. The second song has a chorus start near the start of the song and controls the number of times the first song is repeated, so that the end of the second song is regarded as the passage of the alarm target. It is set as the structure controlled as follows. In this way, rust reproduction starts from a point of time approximately 10 to 30 seconds before the point of time when the alarm object is considered to have passed. Further, it is possible to easily increase the possibility that the reproduction of the music is finished when it is considered that the alarm target has passed. That is, for example, the number of times of reproduction of the first song is controlled so that the reproduction of the song is finished when it is considered to pass the alarm target, taking into account the length of the second song. .

  In addition, as a configuration for performing control to acquire information on the moving speed at a time before the time of outputting the warning sound and determine the number of repetitions of the first song based on the information about the moving speed. Also good. In this way, it is possible to easily increase the possibility that the reproduction of the music is finished when it is considered that the alarm target has passed. For example, when the number of repetitions of the first song is 40 km / h, the number of repetitions may be twice the number of times when the speed is 80 km / h.

  In the present embodiment, an alarm sound including the content related to the distance to the alarm target is output as the alarm sound, and the time required from the start of playback of the song 2 as the second song to the end of the playback and the alarm sound are output. Based on the average speed, which is information related to the moving speed from 2400 m to 1 km, which is the time before the time, the content of the alarm of several hundred meters, which is the content related to the distance to the alarm target, which is the content of the alarm sound. The configuration is determined.

  The content related to the distance to the alarm target, which is the content of the alarm sound, is the movement speed before the time when the alarm sound is output and the time required from the start of playback of the second song to the end of playback. To be determined. Therefore, it is easy to make the information related to the distance that is the content of the alarm sound close to the actual distance, and at the time of the start of playback of the rust portion of the song and the start time of the output of the alarm sound, It is possible to easily suppress variations related to the approaching state. In particular, since the time required from the start of playback of the second song to the end of playback is set to a fixed time (fixed time), the calculation becomes easy.

  As an alarm sound, an alarm sound including the content related to the distance to the alarm target is output, the length from the start of the song to the end of the song is constant at 19 seconds, and the end of the song is the target of the alarm It is set as the structure controlled so that it may become a time point considered to pass. Therefore, it is possible to easily increase the possibility that the end point of the song is the time point that is regarded as the passage of the alarm target. In this embodiment, the length from the start point of the song rust to the end point of the song is 19 seconds, but it may be a fixed fixed number of seconds of about 10 to 30 seconds.

  In the present embodiment, an alarm sound including the content related to the distance to the alarm target is output as the alarm sound, and the approach distance with the alarm target at the time of starting the rust of the song is set before the time when the alarm sound is output. The content related to the distance to the alarm target of the alarm sound is changed according to the estimated distance. Therefore, the content regarding the distance close to the distance to the actual alarm target is output as the alarm sound.

  In the present embodiment, an alarm sound including the content related to the distance to the alarm target is output as the alarm sound, and the content related to the distance to the alarm target that is the content of the alarm sound is determined. The configuration is based on the previous movement state. For this reason, it is possible to improve the accuracy of the content related to the distance to the alarm target, which is the content of the alarm sound. Accordingly, it is possible to prevent a difference between the content of the alarm sound and the state of approach to the actual alarm target from causing a sense of incongruity or miscommunication as having passed through the actual alarm target. For example, speed may be used as the moving state.

  In the present embodiment, the content related to the distance to the alarm target includes information corresponding to a plurality of stages corresponding to the distance, and the content of any stage is output as alarm sound according to the distance. Therefore, it is possible to easily grasp how far the current position is to the alarm target. In the present embodiment, the distance can be known in three stages of 400 m, 500 m, and 600 m.

  In the present embodiment, as the warning sound, the distance until the current position reaches the warning target is notified by voice. However, the time until the current position reaches the warning target may be notified by voice. Moreover, you may make it alert | report both distance and time with an audio | voice. In this way, it is possible to reliably know how long it will take to reach the alarm target, and it is also possible to know that the approach alarm is being performed by an alarm by the music alarm function. Accordingly, it is possible to realize an approach warning that makes it easier to understand the approach warning by sound than in the past, is bothersome, and can maintain a sense of urgency.

  In this embodiment, as the approach to the alarm target, the BGM alarm is performed when the position of the alarm target stored in advance and the current position are in a predetermined approach relationship. For example, the radar wave alarm function When the microwave receiver 14 receives a radio wave having a frequency emitted from the alarm target and the reception status of the radio wave reaches the first signal intensity, the BGM alarm is started and the signal intensity is first. It is preferable to add a configuration that starts reproduction of the rust portion and outputs the alarm content by voice when the second signal strength is higher than the first signal strength. Similarly, in the wireless alarm function, the wireless receiver 15 starts a BGM alarm when the reception status of the radio wave becomes the first signal strength, and the second signal whose signal strength is higher than the first signal strength. When it becomes strong, it is preferable to add a configuration in which the reproduction of the rust portion is started and the alarm content is output by voice.

  A plurality of alarm sounds may be provided according to the type of the alarm target, and a function of reproducing a music for alarm according to the type of the alarm target that is approaching may be provided. In this way, it is possible to know which type of alarm target is approaching by listening to the audio, and by listening to the song, it is possible to approach which type of alarm target depending on the type of the song. You can know if you are. For example, even if an alarm sound is missed, it is possible to know which alarm object is approaching according to the type of music. Therefore, the approach warning by sound is easier to understand and less troublesome than before.

    The volume of music playback may be set to be lower than the volume of alarm sound output. In this way, it is possible to prevent the content of the alarm sound from becoming difficult to hear due to the reproduction of the music, and it is possible to know the alarm content more reliably.

  It may be configured to perform control for separately setting the volume of the alarm sound output and the volume of the music playback. For example, a slider for individually setting the output volume of the alarm sound and the playback volume of the song is displayed, and the volume at the position touched by each slider on the touch panel 6 is set as the respective volume. It is good to have a configuration to In this way, it is possible to individually set both volumes according to the operation from the user. Both the alarm sound and the song can be easily heard according to the situation of each individual and each vehicle.

  In the present embodiment, the radar detector has been described as an example, but it can be implemented as a function of various electronic devices. For example, you may incorporate as a function of a navigation apparatus, a drive recorder, and a car audio. In addition, the numerical values described in the present embodiment may be appropriately changed to values that exhibit an effect through experiments and the like. The screen size of the display unit 5, various time settings, and the like can be arbitrarily set within the scope of the effects of the present invention. Further, the control unit 18 is provided with a function of setting the priority order of each function and alarm based on an instruction from the user from the remote controller 17 or the like, and the control unit 18 performs processing in this set priority order. It may be configured.

  Further, in the above-described embodiment, the apparatus includes the database 19 that stores various types of information, and the control unit 18 accesses the database 19 to read out necessary information and performs various types of processing. It is not limited to. For example, part or all of the information registered in the database 19 is registered in the server. The radar detector and other electronic devices / devices may have a function of communicating with the server, and the control unit 18 may access the server as appropriate, acquire necessary information, and execute a process. Furthermore, at least a part of the function of the control unit 18 may be placed on a server, the function may be executed on the server, and an electronic device owned by the user may acquire the execution result.

  The functions as the control system of the above-described embodiment are configured as a program for causing a computer included in the control unit 18 to realize the function. However, the present invention is not limited to this, and the program is distributed and distributed to a plurality of computers. Also good.
