Description

  The present invention relates to a display control apparatus and a display control method for an in-vehicle display, and is particularly suitable for use in an apparatus and a method for controlling display / non-display of information on at least two in-vehicle displays.

  Generally, as a display mounted on a vehicle, a liquid crystal display device installed on a center console between a driver seat and a passenger seat is used. There is also a vehicle in which an instrument panel (hereinafter referred to as an instrument panel) assembled on a dashboard is configured by a liquid crystal display device. Furthermore, a head-up display (HUD) that projects and displays information on a predetermined area of the windshield is also provided to reduce the driver's line-of-sight movement and improve visibility.

  These in-vehicle displays display navigation information for guiding the vehicle to the destination for guidance in addition to the driving support information necessary for driving the vehicle, such as the driving speed, the engine speed, and the remaining amount of fuel. . In addition, it is necessary to indicate the operation contents when operating an entertainment vehicle-mounted device (hereinafter referred to as an entertainment vehicle-mounted device), such as a radio tuning frequency, music selection content recorded on a DVD or hard disk, and volume level. In general, entertainment information is also displayed.

  The driving support information and the navigation information are essential information for the driver, but the entertainment information is not necessarily necessary information. If entertainment information that is not essential in this way is displayed carelessly on the HUD, for the driver who is driving, the entertainment information may get in the field of view and the attention to driving may be killed. there were.

  In particular, when a passenger other than the driver operates the entertainment system vehicle-mounted device, there is little need for the driver to check the contents by viewing the entertainment information. Nevertheless, if entertainment information is inadvertently displayed on the instrument panel LCD (hereinafter referred to as instrument panel display) or the HUD, which is easy to enter the driver's field of view, the driver can display an unintended entertainment information. There was a problem that attention could be killed.

  In order to prevent the driver from inadvertently seeing the display information of the HUD when driving in a highly dangerous state, the vehicle traveling speed is a predetermined value or more and the rotational angular speed is a predetermined value. A technique has been proposed in which information is prohibited from being displayed on the HUD on the condition described above (see, for example, Patent Document 1).

JP 2009-57013 A

  However, in the technique described in Patent Document 1, information display on the HUD is prohibited only when driving in a high-risk state. In other states, it is unnecessary for the driver. Information may be displayed inadvertently on the HUD. In addition, the technique described in Patent Document 1 also has a problem that information about a vehicle necessary for the driver disappears from the HUD when driving in a highly dangerous state.

  The present invention has been made to solve such a problem, and it is possible to more appropriately control the display / non-display of entertainment information that is not essential for the driver according to the situation. With the goal.

  In order to solve the above-described problems, in the present invention, whether or not the display information to be displayed on the in-vehicle display is entertainment information, whether or not the operator for the entertainment-based in-vehicle device is a driver, Depending on whether display information is displayed on at least two of the display, instrument panel display, and head-up display, display / non-display of the display information on the vehicle-mounted display is controlled. Yes. Further, the display information display / non-display may be controlled by further adding a determination result as to whether the operator's operation is for the steering operation unit.

  According to the present invention configured as described above, display / non-display on the in-vehicle display is controlled only when the display information is entertainment information. In addition, when the display information is entertainment information, it is not a simple determination of whether or not the vehicle is driving in a high-risk state. Who is the operator, which vehicle display should display the display information, and where the operation location is The display / non-display of display information on the in-vehicle display is controlled according to the result of detailed situation determination such as where. As a result, the driving support information and navigation information necessary for driving are always displayed on the in-vehicle display, and the display / non-display of entertainment information that is not essential for the driver can be controlled more appropriately according to the situation. Can do.

It is a figure which shows the structural example of the vehicle-mounted system to which the display control apparatus to the vehicle-mounted display by this embodiment is applied. It is a figure which arranges and shows the contents of display control by a display control part of this embodiment. It is a figure which shows an example of the display information displayed on HUD of this embodiment. It is a flowchart which shows the operation example of the multi-display control part by this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of an in-vehicle system to which a display control device for an in-vehicle display according to the present embodiment is applied.

  As shown in FIG. 1, the in-vehicle system of the present embodiment projects and displays information on a center display 1 installed on a vehicle center console, an instrument panel display 2 installed on an instrument panel, and a windshield. A head-up display (HUD) 3, a center operation unit 4 configured as a touch panel overlaid on the center display 1, a steering operation unit 5 installed on the steering wheel, and an ECU (Electronic Control) that performs various electrical controls in the vehicle Unit) 6.

  The ECU 6 includes a multi-display control unit 10 (corresponding to a display control device for an in-vehicle display according to the present invention) and a display information generation unit 20. The multi-display control unit 10 includes a display information input unit 11, an information type determination unit 12, an operator determination unit 13, an operation place determination unit 14, and a display control unit 15 as functional configurations. The multi-display control unit 10 controls the display / non-display of information with respect to the center display 1, the instrument panel display 2, and the HUD 3 (hereinafter collectively referred to as “vehicle-mounted displays 1 to 3”) by having these functional configurations. To do.

  The display information input unit 11 inputs display information to be displayed on the in-vehicle displays 1 to 3. The display information input by the display information input unit 11 is generated by the display information generation unit 20.

  The display information generating unit 20 is connected to various sensors (not shown) such as a vehicle speed sensor, an engine rotational speed sensor, and a fuel sensor, and based on output information from the various sensors, the traveling speed, the engine rotational speed, Driving support information such as the remaining amount of fuel is generated.

  The display information generating unit 20 is also connected to a navigation device (not shown), and navigation information (for example, guidance for guiding the vehicle to a destination based on output information from the navigation device) , An arrow indicating the guiding direction) is generated.

  Further, the display information generation unit 20 is also connected to an entertainment system on-vehicle device (not shown) such as an audio playback device or a DVD playback device, and the entertainment information such as a radio tuning frequency, music selection content, volume level, etc. Entertainment information necessary to indicate the operation content when operating on the vehicle-mounted in-vehicle device is generated. In addition, operation with respect to the entertainment system vehicle-mounted device can be performed using either the center operation unit 4 or the steering operation unit 5.

  As described above, the display information input unit 11 inputs the driving support information, navigation information, and entertainment information generated by the display information generation unit 20 as display information to be displayed on the in-vehicle displays 1 to 3.

  The information type determination unit 12 determines whether the type of display information input by the display information input unit 11 is entertainment information. For example, the information type determination unit 12 analyzes the display information input by the display information input unit 11 to determine whether or not it represents entertainment information. When the display information generating unit 20 generates display information, source information indicating the information source may be added. In this way, the information type determination unit 12 can determine whether the display information is entertainment information based on the source information given to the display information input by the display information input unit 11.

  The operator determination part 13 determines whether the user who performed operation with respect to the entertainment system vehicle-mounted device is a driver. Specifically, the operator determination unit 13 determines that the operator is a driver when detecting that an operation on the steering operation unit 5 has been performed. Which of the center operation unit 4 and the steering operation unit 5 is operated is detected by confirming from which operation unit the operation information is sent to the display information generation unit 20. Is possible.

  When the display information generation unit 20 generates the display information, operation source information indicating whether the operation information generated from the center operation unit 4 or the steering operation unit 5 is a trigger is added. It may be. In this way, the operator determination unit 13 detects whether or not the operation is performed on the steering operation unit 5 based on the operation source information given to the display information input by the display information input unit 11, and the operator Whether or not is a driver can be determined.

  When the operator determination unit 13 detects that the operation on the center operation unit 4 has been performed, the operator determination unit 13 further determines whether or not the operation is performed by the driver. A known method can be employed for this determination. For example, infrared sensors are respectively provided on the right side (driver's seat side) and the left side (passenger seat side) of the center operation unit 4. The operator determination unit 13 determines that the operation is performed by the driver when the right infrared sensor reacts, and determines that the operation is not performed by the driver when the left infrared sensor reacts.

  The operation place determination unit 14 determines whether the operation on the entertainment vehicle-mounted device is performed on the center operation unit 4 or on the steering operation unit 5. As described above, this determination can be performed by confirming whether the operation information is sent from the center operation unit 4 or the steering operation unit 5 to the display information generation unit 20.

  Alternatively, if the operation source information is added to the display information generated by the display information generation unit 20, it can be determined whether the operation is for the steering operation unit 5 based on the operation source information. If an infrared sensor is provided in the vicinity of the center operation unit 4, if the infrared sensor is reacting when operation information is generated, it is determined that the operation is performed on the center operation unit 4, and if the infrared sensor is not responding. It can be determined that the operation is performed on the steering operation unit 5.

  The display control unit 15 applies the display information input by the display information input unit 11 to the in-vehicle displays 1 to 3 according to the contents of the determination results by the information type determination unit 12, the operator determination unit 13, and the operation place determination unit 14. The display / non-display is controlled according to which of the in-vehicle displays 1 to 3 is displayed.

  FIG. 2 is a diagram showing the contents of display control by the display control unit 15 in an organized manner. If the information type determination unit 12 determines that the display information input by the display information input unit 11 is travel support information or navigation information, the display control unit 15 displays the display information on the in-vehicle displays 1 to 3. Always display. On the other hand, when the information type determination unit 12 determines that the display information input by the display information input unit 11 is entertainment information, the display control unit 15 applies to the in-vehicle displays 1 to 3 according to the contents shown in FIG. Perform display control.

  First, display control for the center display 1 will be described. As shown in FIG. 2, the display control unit 15 always stores the entertainment information input by the display information input unit 11 on the center display 1 regardless of the determination results by the operator determination unit 13 and the operation place determination unit 14. Control to display. This is because even if entertainment information is displayed on the center display 1, it does not get in the way of the driver's field of view.

  Next, display control for the HUD 3 will be described. FIG. 3 is a diagram illustrating an example of display information displayed on the HUD 3. In the example shown in FIG. 3, a traveling speed (60 km / h) as traveling support information, a guidance direction arrow as navigation information, and a radio channel selection frequency (Tokyo FM 80.0 MHz) as entertainment information are displayed. Of these, the driving support information and the navigation information are always displayed on the HUD 3. On the other hand, the entertainment information is display-controlled according to the contents shown in FIG.

  As shown in FIG. 2, the display control unit 15 is determined by the operator determination unit 13 that the operator of the entertainment vehicle-mounted device is not a driver (that is, a passenger other than the driver is an operator). At this time, control is performed so that entertainment information is not displayed on the HUD 3. That is, for example, even if the passenger performs an operation on the entertainment system vehicle-mounted device and selects the radio, the information on the radio channel selection frequency shown in FIG. 3 is not displayed on the HUD 3.

  The fact that the operator is a passenger means that an operation has been performed on the center operation unit 4 installed at the same place as the center display 1. At this time, since the entertainment information is displayed on the center display 1, the passenger can check the entertainment information on the center display 1. On the other hand, when the passenger operates the entertainment system vehicle-mounted device, it is not necessary for the driver to check the contents by looking at the entertainment information. Therefore, the entertainment information is not displayed on the HUD 3 that easily enters the driver's field of view so as not to disturb the driver during driving.

  In addition, when the operator determining unit 13 determines that the operator of the entertainment in-vehicle device is a driver, the display control unit 15 determines that the operation on the entertainment in-vehicle device is for the center operation unit 4. When it is determined by the determination unit 14, control is performed so that entertainment information is not displayed on the HUD 3. On the other hand, when the operation place determination unit 14 determines that the operation on the entertainment system vehicle-mounted device is on the steering operation unit 5, the display control unit 15 displays the entertainment information on the HUD 3 for a certain period of time and then deletes it. To control.

  That is, the fact that the operator is the driver and the center operation unit 4 is being operated is considered to be an operation while the vehicle is stopped or traveling at a relatively low speed. At this time, since the entertainment information is displayed on the center display 1 installed in the same place as the operated center operation unit 4, the driver can check the entertainment information on the center display 1. Therefore, entertainment information is not displayed on the HUD 3.

  On the other hand, when the operator is a driver and an operation is being performed on the steering operation unit 5, in order to enable the driver who has performed the operation to easily check the entertainment information with a small line of sight movement, Display entertainment information. However, the confirmation may be temporary, and the display of entertainment information may interfere with driving. Therefore, after the entertainment information is displayed for a certain time, it is deleted. For example, when the driver operates the steering operation unit 5 to select a radio channel, the radio channel frequency information shown in FIG. 3 is displayed on the HUD 3 for a certain period of time and then deleted.

  Finally, display control for the instrument panel display 2 will be described. As shown in FIG. 2, the display control unit 15 is determined by the operator determination unit 13 that the operator of the entertainment system vehicle-mounted device is not a driver (that is, a passenger other than the driver is an operator). Controls not to display entertainment information on the instrument panel display 2. As described above, the fact that the operator is a passenger is because the entertainment information can be confirmed on the center display 1.

  On the other hand, if the operator determination unit 13 determines that the operator of the entertainment system vehicle-mounted device is a driver, the display control unit 15 displays the entertainment information regardless of the determination result by the operation location determination unit 14. Control is performed so as to display on the instrument panel display 2. Although the instrument panel display 2 is installed in a place where it is easy to enter the driver's field of vision, it is in a position that cannot be seen unless it is consciously directed, so even if entertainment information is displayed, it may be a hindrance to driving Because there is no. Here, the entertainment information is displayed on the instrument panel display 2 so that the driver can confirm the entertainment information when the driver consciously points his gaze at the instrument panel display 2, but when the operation on the center operation unit 4 is performed, the information is not displayed. You may make it display.

  FIG. 4 is a flowchart showing the operation of the multi-display control unit 10 according to the present embodiment. The flowchart shown in FIG. 4 starts when some display information is generated in the display information generation unit 20 of the ECU 6. In FIG. 4, the display information input unit 11 of the multi-display control unit 10 inputs display information to be displayed on the in-vehicle displays 1 to 3 (step S1).

  When display information is input through the display information input unit 11, the information type determination unit 12 determines whether the display information is entertainment information (step S2). When the information type determination unit 12 determines that the input display information is not entertainment information (that is, driving support information or navigation information), the display control unit 15 displays the display information on the in-vehicle display. 1 to 3 are displayed (step S3).

  On the other hand, when the information type determination unit 12 determines that the input display information is entertainment information, the operator determination unit 13 performs an operation on the entertainment-based in-vehicle device from which the entertainment information is generated. It is determined whether or not the user is a driver (step S4). When the operator determination unit 13 determines that the operator is not a driver (that is, the operator is a passenger other than the driver), the display control unit 15 displays the entertainment information on the center display. Only 1 is displayed (step S5).

  When the operator determination unit 13 determines that the operator of the entertainment system vehicle-mounted device is a driver, the operation place determination unit 14 performs an operation by the driver on the steering operation unit 5. It is determined whether or not it has been (step S6). Here, when the operation place determination unit 14 determines that the operation is for the steering operation unit 5, the display control unit 15 displays entertainment information on the center display 1 and the instrument panel display 2, while the HUD 3 The entertainment information is displayed for a predetermined time (step S7).

  On the other hand, when the operation location determination unit 14 determines that the operation is not an operation with respect to the steering operation unit 5 (that is, an operation with respect to the center operation unit 4), the display control unit 15 performs the operations on the center display 1 and the instrument panel display 2. Only entertainment information is displayed (step S8).

  As described above in detail, in the present embodiment, whether the display information to be displayed on the in-vehicle displays 1 to 3 is entertainment information, whether the operator for the entertainment-type in-vehicle device is a driver, Depending on the determination result whether or not the operation is for the steering operation unit 5 and whether the display information is displayed on the center display 1, the instrument panel display 2 or the HUD 3, the vehicle-mounted display 1 to 1 of the display information is displayed. The display / non-display for 3 is controlled.

  According to the present embodiment configured as described above, display / non-display on the in-vehicle displays 1 to 3 is controlled only when the display information is entertainment information. Further, when the display information is entertainment information, the in-vehicle displays 1 to 3 are determined according to the result of detailed situation determination such as who is the operator, which is the in-vehicle display 1 to 3 to display the display information, and where is the operation location. Display / non-display of display information for is controlled. As a result, the driving support information and the navigation information necessary for driving are always displayed on the in-vehicle displays 1 to 3, and the entertainment information that is not essential for the driver can be displayed / hidden more appropriately according to the situation. Can be controlled.

  In the above-described embodiment, an example of an in-vehicle system including the center display 1, the instrument panel display 2, and the HUD 3 has been described, but the present invention is not limited to this.
