  However, there is a problem that it is difficult for the driver to understand what kind of message is displayed because such a display device is installed facing outward from the vehicle.

  Therefore, the present invention was made to solve such problems and the like, and it is easier for the operator to grasp the contents displayed toward the outside of the vehicle than in the past, and a user-friendly control system or the like is provided. The purpose is to provide.

  (1) In order to achieve the above-described object, the control system according to the present invention includes a first display means for displaying toward the outside of the vehicle and a first display for displaying toward the operator in the vehicle. A control system that controls the two display means, determines the display contents, performs control to display the determined display contents on the first display means, and relates to the display contents on the second display means Control means for performing control to display information is provided.

  In this way, the operator can confirm what kind of display content is displayed on the first display means that displays the vehicle toward the outside by looking at the second display means. In particular, when the operator is a driver, the driver can easily confirm at a glance what kind of display is being made in the outward direction.

  The “information regarding the display content” may be the display content itself, information obtained by processing the display content, information associated with the display content, or the like, as long as the display content can be understood by the operator.

  (2) The first display means is installed with the forward direction of the vehicle as the outer direction, and the control means displays the display contents on the first display means as a horizontally reversed image, and The information related to the display content displayed on the second display means may be configured not to be a horizontally reversed image.

  If it does in this way, the driver of the vehicle ahead of this vehicle can check easily the display contents displayed on the 1st display means installed in this vehicle with a back mirror. For example, even when the display content is a character string, the character string reflected on the rearview mirror is displayed horizontally reversed. Therefore, the character string reversed left-right displayed on the first display means remains on the rearview mirror. A character string that can be read and is not reversed is displayed. On the other hand, the display content is displayed on the second display means as an image that is not reversed left and right toward the operator in the vehicle. Therefore, the operator can easily confirm what the display content displayed on the first display means is by looking directly at the second display means.

  (3) The control means controls the forward display means installed with the front direction of the vehicle as the first display means and the backward display means installed with the rear direction of the vehicle directed.

It is clearly communicated to everyone and is good for the mood. In addition, you can be sure of your will during the night. As an example of use, if you give a road at a meeting point, etc., if you flash the hazard of the vehicle, the text “Thank you” will be displayed, so special operation for display is required You can concentrate on driving. Moreover, as a result of eliminating the intention expression by the driver's gesture, the driver can concentrate on driving.

  In the present embodiment, as “information related to display content”, the display content displayed on the rear display 41 is reduced and displayed on the display unit 5 as the rear display display content display unit 52, and the reduced display content is displayed. Is displayed on the display state display unit 53 as to whether or not is currently displayed on the rear display 41. This is an example, and the information related to the display content displayed on the rear display 41 displayed on the display unit 5 may be information reminiscent of the display content or the like as long as the display content can be understood by the operator. For example, it may be displayed as an icon.

  In the present embodiment, “thank you” is displayed on the rear display 41 when there is a hazard and the gear is not back. As in the present embodiment, conditions based on a plurality of different vehicle information may be set. This is because it is often difficult to judge and display a plurality of different vehicle states during driving. These conditions can be set arbitrarily. Moreover, you may make it display based on vehicle information other than these.

  For example, the control unit 18 acquires the blinker state as the vehicle state, and expresses gratitude when a hazard is issued within a predetermined time after the blinker state is displayed on the right or left side. The character string shown may be displayed. Hazard is used to express appreciation, so in this way, the user can display the appreciation by simply performing normal driving operation without any special operation for display. It can be displayed on the device 41. Further, the control unit 18 acquires the operation state of the horn, and when the operation state of the horn is a ringing instruction with a predetermined length or less, the character of the content to be notified to the driver of the preceding vehicle as shown in FIG. It is good also as a structure to display.

  For example, if one of the stop lamps of the previous car is cut off, the letters “The lamp is off” as shown in FIG. It ’s a good idea to display characters like “I ’m doing it.” In this way, if you light the horn, it seems that the driver of the previous car will see the following car in the rearview mirror. Can be recognized. For example, there may be a case where the driver of the front vehicle does not readily notice a failure in a part that can be seen from the rear vehicle, such as when the stop lamp behind the front vehicle is turned off. Can be made.

  The contents displayed on the rear display unit 41 and the corresponding display unit display content display unit 52 and display state display unit 53 of the display unit 5 in S130 and S140 are stored as character strings and character fonts. The data may be expanded and displayed in association with each other, or may be stored as image data, read out, and displayed in association with each other. These data may be stored in the database 19. In particular, the data is stored in the memory card 14, and the data stored in the memory card 14 is read through the memory card reader 13 and displayed. It is good to do. In this way, the recorded contents of the memory card 14 can be rewritten with a personal computer or the like, and the displayed contents can be freely replaced. Further, the display content can be changed by simply replacing the memory card 14. In this case, the memory card reader 13 may be built in the radar detector. In other words, the control unit 18 may be configured to store display contents as information to be displayed on the front display / rear display 41 and the display unit 5 in the memory card 14 and to update the display contents. In this way, display contents that are not always fixed, but new display contents can be displayed outside the vehicle as needed. Further, for example, the update is performed by connecting a communication device such as a mobile phone to the control unit 18, obtaining update information from a communication partner device via the communication device, and based on the update information on the contents of the memory card 13 and the database 19. May be updated.

  Further, for example, a plurality of different display contents that can be displayed on the front display or the rear display are stored in the database 19 or the like, and the control unit 18 displays information on the plurality of different display contents stored in the database 19 on the display unit 5. The display content to be displayed on the rear display 41 is selected from the information regarding the plurality of different display contents displayed, and the selected display content is displayed on the front display or the rear display 41. The display unit 5 may be configured to display information related to the selected display content. In this way, it is easy to select and display what is desired to be displayed from a plurality of different display contents. For example, a selection screen is provided to detect and select the operation of the remote controller 17 through the remote control receiver 16 from among a plurality of display contents, and the display selected on this screen. The contents may be displayed. For example, when the pressing of the setting button of the remote controller 17 is detected, a plurality of display contents are displayed in a list on the display unit 5, and the operation of the cross button and the determination button is detected to display the display contents selected from the list. It is better to detect.

  Furthermore, when a multi-function remote controller comprising a large number of buttons different from the remote controller 17 is provided, and the controller 18 detects that the multi-function remote controller button has been pressed, You may make it display the display content matched beforehand with the pressed button by the process similar to the process of S130. For example, buttons 1 to 7 may be provided, and display contents may be displayed on the rear display unit 41 and the rear display unit display content display unit 52 of the display unit 5 corresponding to the number of the pressed button. . For example, “Thank you” is displayed as the first display content and “Back” is displayed as the second display content as the display content displayed on the rear display 41 and the rear display display content display unit 52 of the display unit 5 corresponding thereto. ”,“ Please come first ”as the 3rd display content,“ Children are riding ”as the 4th display content,“ Congestion ahead ”as the 5th display content,“ Left and right ”as the 6th display content It is preferable to store the display content of “parking” as the display content of No. 7 and display the display content of the number corresponding to the number of the pressed button on the remote control. If it does in this way, based on an operator's intention, the content which wants to convey with a remote control can be selected once, and the content can be conveyed to a succeeding vehicle with a character. Further, when the pressing of the button of the multi-function remote controller is not detected, the rear display 41 may be configured to function as a brake lamp.

  For example, the control unit 18 performs control to display on the front display / rear display 41 when an instruction to display the determined display content on the front display / rear display 41 is input, and displays the determined display content. When the instruction to perform is not input, the front display / rear display 41 may be configured to display information on the vehicle state. In this way, when the display instruction is input from the operator, the determined display content is displayed on the rear display 41, and when the display instruction is not input from the operator, information on the vehicle state is displayed on the rear display. 41 is automatically displayed. Therefore, when the operator wants to notify the outside of the vehicle, the contents can be displayed by inputting the display instruction. When the operator does not want to notify the outside of the vehicle, the display instruction is displayed. In situations where input is not possible, the vehicle state can be automatically displayed outside the vehicle. Therefore, a person outside the vehicle can know the vehicle state by viewing the display content displayed on the front indicator / rear indicator 41, and the driver of the vehicle is also displayed on the display unit 5. You can know the contents by looking at the information about the contents. The control unit 18 acquires the state of the brake of the vehicle as the vehicle state, and when the brake state is a state where the brake is applied, the control unit 18 displays information regarding that the brake is applied as the information regarding the vehicle state. The display 41 may be configured to display. In this way, for example, a person outside the vehicle, such as the following vehicle, can know the brake state of the vehicle by looking at the display content displayed on the rear display 41, and the driver of the vehicle Etc. can also know the contents by looking at the information on the display contents displayed on the display unit 5. In addition, the control unit 18 acquires the vehicle deceleration state from the vehicle speed acquired as the vehicle state, and when the vehicle is in the deceleration state, the control unit 18 displays information on the deceleration on the rear display 41 as information on the vehicle state. Good. In this way, for example, a person outside the vehicle such as the driver of the following vehicle can know the deceleration state of the vehicle by seeing the display content displayed on the rear display 41, and The driver or the like can also know the contents by viewing the information related to the display contents displayed on the display unit 5.

  The display content includes at least one of a character string indicating an intention of gratitude, a character string indicating an intention to change the course, a character string indicating a characteristic of a person riding in the own vehicle, and a character string regarding a direction in which the own vehicle is moved. One of them may be stored in advance. In this way, it is possible to select the display contents stored in advance and display them outside the vehicle without inputting the display contents one by one.

  In the present embodiment, the contents displayed on the rear display 41 and the display status display 53 of the rear display 41 and the display unit 5 corresponding thereto in S130 and S140 are lit but flashed. You may do it. The display may be moved such as by performing a predetermined scroll display. In addition, a setting screen for setting whether or not to display on the rear display 41 and the rear display display content display unit 52 and the display state display unit 53 of the display unit 5 corresponding thereto is provided, and the operation of the remote controller 17 or the like is detected. Then, setting may be performed, and it may be determined whether to display based on this setting.

  The control signal for the control unit 18 to control the rear display unit 41 and the display unit 5 may be transmitted by either wired or wireless. For example, the control unit 18 and the rear display 41 may be connected (wired) by wiring, or may be wireless using wireless communication such as Bluetooth.

  In the present embodiment, the rear indicator 41 is installed with the rear direction of the vehicle facing outward as an outward direction, but the rear indicator 41 is installed on the dashboard of the vehicle with the front direction of the vehicle facing forward. You may make it function as a display. In this case, the control unit 18 may display the display content on the front display as a horizontally reversed image, and the display content displayed on the display unit 5 may not be a horizontally reversed image. For example, as shown in FIG. 7A, a character string obtained by horizontally inverting the character string “The lamp is off” is displayed on the front display, and the display unit 5 shows the character string shown in FIG. 7B. The character string “The lamp is off” that is not reversed left and right is displayed. When the driver of the vehicle ahead sees the rearview mirror, the display content displayed on the front indicator appears on the mirror as shown in FIG. Therefore, the driver of the vehicle ahead of the vehicle equipped with the radar detector can easily confirm the display content displayed on the front indicator installed on the vehicle by the rearview mirror. In this way, when the display content is a character string, the character string reflected in the rearview mirror is displayed with the left and right reversed, so the character string that is reversed left and right displayed on the front display is displayed on the rearview mirror. A character string that can be read as it is and is not reversed is displayed. On the other hand, the display content is displayed on the display unit 5 as an image that is not reversed left and right toward the operator in the vehicle. Therefore, the operator can easily confirm what the display content displayed on the front display is by looking directly at the display unit 5.

  Furthermore, it is good also as a structure which provides both a front indicator and a back indicator, and connects and controls to the control part 18, respectively. In this case, as described above, the control unit 18 displays the character string on the front display as a horizontally reversed image, and displays the character string on the rear display without being horizontally reversed. In this way, for example, the driver of the vehicle in front of the vehicle can directly recognize the display content displayed on the front indicator by the rearview mirror, and the driver of the vehicle behind the vehicle displays on the rear indicator. The displayed content can be recognized as it is, and the driver of the vehicle can grasp the display content displayed on the front display and the rear display based on the information on the display content displayed on the display unit 5. For example, the display on the display unit 5 may be switched between the display of FIG. 5B and the display of FIG. 7B at regular intervals, or the display of FIG. 5B and FIG. The display of (b) may be performed simultaneously within one screen.

  Further, the control unit 18 selects and inputs whether or not the display of the front display is highlighted by the remote controller 17, and when the instruction for the reverse display is input, the display of the front display is performed as described above. It is preferable that the display is reversed. For example, a setting screen for determining whether to reversely display the display on the front display may be provided, and an operation of the remote controller 17 may be detected to perform setting. In addition, the setting screen may not be provided, and the display may be reversed while the selection button of the remote controller 17 is detected, and the normal display may be performed without the reverse display when the selection button of the remote control 17 is not detected.

  It should be noted that the input of the instruction from the user may be performed by the remote controller 17, the state of the signal line such as the operation switch of the vehicle may be input, the data is acquired from the in-vehicle LAN provided in the vehicle, Content corresponding to an instruction from the user in the data may be input. For example, when a lever operation for passing a vehicle light (short-time lever-on state) is detected and the passing operation of the lever is detected, the display is reversed. When the passing operation is not detected, the operation is reversed. It is good to display normally without displaying.

  If it does in this way, while being able to perform the display according to the intention of operators, such as a driver, toward the outside of a vehicle, the driver | operator himself can confirm the content easily. For example, when displaying a character string on the front display, it can be selected whether or not to reverse display by an operation, so that it can be read from a pedestrian or through a rearview mirror. In this way, depending on what kind of situation the person viewing the front display is, the operator can select whether to reversely display the display on the front display according to the situation.

  In addition, it is good to display the information which shows whether it is reverse-displayed with respect to the front indicator on the display part 5. For example, the characters “in front display” in FIG. 7B are changed to “in reverse display in front” and displayed. If it does in this way, it will be easy to confirm whether it is displayed on the front indicator only by looking at the display part 5 by the selected display method.

  The control unit 18 acquires the vehicle state as in the present embodiment, determines whether or not to reversely display the display of the front indicator 41 based on the acquired vehicle state, and determines that the display is reversed. In such a case, the display on the front display may be reversed. For example, an inter-vehicle distance sensor that detects an inter-vehicle distance from the preceding vehicle is connected to the control unit 18, and the inter-vehicle distance sensor detects the inter-vehicle distance from the preceding vehicle, and the detected inter-vehicle distance is within a predetermined distance (for example, within 10 m). ), Display in reverse video. In other cases, display in reverse video should be avoided. In this way, since it is automatically determined whether or not to reversely display according to the vehicle state, the driver or the like does not need to input an instruction whether or not to reversely display.

  In addition, an input screen for inputting a character string of display contents to be displayed on the rear display 41 or the front display is provided, and the character string input on the input screen is stored in the database 19. You may make it display the character string memorize | stored in. For example, it is preferable that the character string “Thank you” shown in FIG. 5 can be edited. For example, a so-called software keyboard may be displayed on the display unit 5 and characters may be selected and input using buttons on the remote controller 17. In this way, the operator can input an arbitrary character string and display the character string outside the vehicle. The input of the character string may be performed by key input or voice input (voice recognition) by connecting a keyboard or a microphone to the control unit 18 as well as the remote controller 17.

The control part 18 is good to set it as the structure which displays an approach alarm also with respect to the front indicator and the back indicator 41 during the alarm by a GPS alarm function. For example, during the alarm by the GPS alarm function, “approaching the speed measuring device” is displayed on the rear display 41. In this way, for example, a person outside the vehicle, such as a driver of the successor, can know that the position of the speed measuring device is approaching by viewing the display content of the rear display 41.
The above-described constituent elements may be appropriately combined to constitute a radar detector.

  In the present embodiment, the power supply can be received by connecting to the cigar socket of the vehicle via the cigar plug cord, but the power supply may be received from the OBD2 connector.

  In this embodiment, the example of the radar detector has been described. However, the present invention can be implemented as a function of various in-vehicle 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 can also be set arbitrarily. 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.
