DETAILED DESCRIPTION

With diversification of content screens, various types of display devices for displaying the content screens are installed. As a configuration equipped with a plurality of display devices in the vehicle interior, for example, an operation display capable of being operated by a user who is a driver while maintaining a driving posture may be arranged at a position relatively close to the driver's seat, and a distant display visible from the user without moving a sight line from forward of a vehicle may be arranged at a position relatively far from the driver's seat.

If a touch panel is provided on both the operation display and the distant display in the above configuration, the user may lose the driving posture when operating the distant display, which may lower operability and safety.

According to one aspect of the present disclosure, a vehicular display control system includes first and second displays disposed in a vehicle interior, a screen switching operation receiver, and a screen switching controller. The screen switching operation receiver is disposed at a position in the vehicle interior operable by a user while maintaining a driving posture, and is configured to receive a first screen switching operation and a second screen switching operation from the user. The screen switching controller is configured to perform a first screen switching control for switching a display of a content screen on the first display when the screen switching operation receiver receives the first screen switching operation from the user and perform a second screen switching control for switching a display of a content screen on the second display when the screen switching operation receiver receives the second screen switching operation from the user.

Regardless of the positions where the first display and the second display are arranged in the vehicle interior, the user can switch the display of the content screen on each of the first display and the second display by performing the screen switching operation while maintaining the driving posture. As a result, the user can appropriately switch the display of the content screen on the plurality of displays without impairing the operability and safety.

Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In the present embodiment, a configuration applied to a vehicle in which a driver's seat is arranged on a left side when viewed in a forward direction of a vehicle will be described as an example. As shown in FIG. 1, in a vehicle interior, an operation display 2 is arranged on a front surface portion 3a of a dashboard 3 on the right of a steering wheel 1 (that is closer to a center of the vehicle interior). That is, the operation display 2 is arranged at a position relatively close to the driver's seat and is operable by a user while maintaining a driving posture. The user can operate the operation display 2 while maintaining the driving posture, but when visually recognizing a screen of the operation display 2, a sight line moves from forward of the vehicle. A cooperative effect display 4 is arranged above the operation display 2.

Between the steering wheel 1 and a windshield 5, a meter display 6 and a distant display 7 are arranged side by side in a left-right direction on the upper surface portion 3b of the dashboard 3 within a range that does not obstruct a front view of the user. That is, the distant display 7 is arranged at a position relatively far from the driver's seat and visible to the user without moving the sight line from forward of the vehicle. The user can visually recognize a screen of the distant display 7 without moving the sight line from forward of the vehicle. The meter display 6 and the distant display 7 may be integrally configured or may be configured separately. On the steering wheel 1, a steering switch 8 operable by the user is arranged. The user can operate the steering switch 8 while maintaining the driving posture. The steering switch 8 may have any shape such as a cross shape, a push type, a toggle type, and a seesaw type.

Next, operation of the above configuration will be described with reference to FIGS. 5 to 24. In the display control ECU 16, the controller 24 performs icon operation determination processing, steering switch operation determination processing, and dial operation determination processing in parallel when the vehicular display control system 15 is activated. Hereinafter, each processing will be described.

(1) Icon Operation Determination Processing

The icon operation determination processing will be described with reference to FIGS. 5 to 13. When the controller 24 starts the icon operation determination processing, the controller 24 monitors whether the user has performed the screen switching operation (S1). When the controller 24 receives the icon operation detection signal from the operation display 2 and determines that the user has performed the screen switching operation (S1: YES), the controller 24 specifies the content of the screen switching operation (S2), and determines which of the operation display 2 and the distant display 7 is a target of the screen switching operation (S3, S4).

When the controller 24 determines that the target of the screen switching operation is the operation display 2 (corresponding to a first screen switching operation) (S3: YES), the controller 24 outputs the screen switching control signal to the content screen display 10 to switch the display of the content screen in the content screen display 10 to the content screen corresponding to the specified icons 11a to 11d (S5, corresponding to a first screen switching control procedure). In addition, the controller 24 outputs the icon display control signal to the icon display 9 to change the display mode of the icons 11a to 11d in response to switching the content screen of the content screen display 10 (S6). Furthermore, the controller 24 outputs the effect control signal to the cooperative effect display 4 to perform the cooperative effect in response to switching the content screen of the content screen display 10 (S7).

When the controller 24 determines that the target of the screen switching operation is the distant display 7 (corresponding to a second screen switching operation) (S4: YES), the controller 24 outputs the screen switching control signal to the content screen display 14 to switch the display of the content screen of the content screen display 14 to the content screen corresponding to the specified icons 11a to 11d (S8, corresponding to a second screen switching control procedure). In addition, the controller 24 outputs the icon display control signal to the icon display 9 to change the display mode of the icons 11a to 11d in response to switching the content screen of the content screen display 10 (S9). Furthermore, the controller 24 outputs the effect control signal to the cooperative effect display 4 to perform the cooperative effect in response to switching the content screen of the content screen display 14 (S10).

The controller 24 determines whether a stop request for the vehicular display control system 15 has be generated (S11), and the above processing is repeated when the controller 24 determines that the stop request for the vehicular display control system 15 has not been generated (S11: NO). The controller 24 determines that the stop request for the vehicular display control system 15 has been generated (S11: YES), for example, when an ACC power supply is switched from on to off when the user gets off the vehicle, and ends the icon operation determination processing.

A specific example will be described below.

(i) A case where a flick operation is assigned as the screen switching operation of the distant display 7 and a press operation is assigned as the screen switching operation of the operation display 2

As shown in FIG. 6, when the user flicks the navigation icon 11a (corresponding to the second predetermined operation) from a state where the air conditioner screen is displayed on the operation display 2 and the audio screen is displayed on the distant display 7, the controller 24 switches the content screen of the distant display 7 from the audio screen to the navigation screen. Then, when the user presses the audio icon 11b (corresponding to the first predetermined operation) from this state, the controller 24 switches the content screen of the operation display 2 from the air conditioner screen to the audio screen.

(ii) A case where a touch operation is assigned as the screen switching operation of the distant display 7 and a press operation is assigned as the screen switching operation of the operation display 2

As shown in FIG. 7, when the user touches the navigation icon 11a (corresponding to the second predetermined operation) from a state where the air conditioner screen is displayed on the operation display 2 and the audio screen is displayed on the distant display 7, the controller 24 switches the content screen of the distant display 7 from the audio screen to the navigation screen. Then, when the user presses the audio icon 11b (corresponding to the first predetermined operation) from this state, the controller 24 switches the content screen of the operation display 2 from the air conditioner screen to the audio screen.

(iii) A case where a touch operation is assigned as the screen switching operation of the distant display 7 and a drag operation is assigned as the screen switching operation of the operation display 2

As shown in FIG. 8, when the user touches the navigation icon 11a (corresponding to the second predetermined operation) from a state where the air conditioner screen is displayed on the operation display 2 and the audio screen is displayed on the distant display 7, the controller 24 switches the content screen of the distant display 7 from the audio screen to the navigation screen. Then, when the user drags the audio icon 11b (corresponding to the first predetermined operation) from this state, the controller 24 switches the content screen of the operation display 2 from the air conditioner screen to the audio screen.

The operation for switching the display of the content screen of the distant display 7 and the operation for switching the display of the content screen of the operation display 2 have only to be different from each other, and may be operations other than the flick operation, the touch operation, the press operation, and the drag operation described above.

Further, the controller 24 changes the display mode of the icons 11a to 11d as follows to notify the content screen displayed on the distant display 7 and the content screen displayed on the operation display 2 at the icon display 9. For example, as shown in FIG. 9, the controller 24 may display an arc-shaped mark 41a (corresponding to second specific information) on an upper portion of one of the icons 11a to 11d corresponding to the content screen displayed on the distant display 7 and may display an arc-shaped mark 41b (corresponding to first specific information) on a lower portion of one of the icons 11a to 11d corresponding to the content screen displayed on the operation display 2. FIG. 9 illustrates a case where the arc-shaped mark 41a is displayed on the upper portion of the audio icon 11b and the arc-shaped mark 41b is displayed on the lower portion of the air conditioner icon 11d.

As another example, as shown in FIG. 10, the controller 24 may display an arrow mark 42a (corresponding to the second specific information) on the upper portion of one of the icons 11a to 11d corresponding to the content screen displayed on the distant display 7 and may display an arrow mark 42b (corresponding to the first specific information) on the lower portion of one of the icons 11a to 11d corresponding to the content screen displayed on the operation display 2. As another example, as shown in FIG. 11, the controller 24 may display an extension portion 43a (corresponding to the second specific information) on the upper portion of one of the icons 11a to 11d corresponding to the content screen displayed on the distant display 7 such that the upper portion extends upward, and may display an extension portion 43b (corresponding to the first specific information) on the lower portion of one of the icons 11a to 11d corresponding to the content screen displayed on the operation display 2 such that the lower portion extends downward.

As another example, as shown in FIG. 12, the controller 24 may display a connection portion 44a (corresponding to the second specific information) on the upper portion of one of the icons 11a to 11d corresponding to the content screen displayed on the distant display 7 such that the upper portion is connected to an upper end portion of the icon display 9, and may display a connection portion 44b (corresponding to the first specific information) on the lower portion of one of the icons 11a to 11d corresponding to the content screen displayed on the operation display 2 such that the lower portion is connected to a lower end portion of the icon display 9. As another example, as shown in FIG. 13, the controller 24 may display one of the icons 11a to 11d corresponding to the content screen displayed on the distant display 7 at a portion shifted upward and may display one of the icons 11a to 11d corresponding to the content screen displayed on the operation display 2 at a portion shifted downward. The controller 24 may change the display mode of the icons 11a to 11d in a way other than the above-described examples.

Further, the controller 24 notifies that the content screen of the distant display 7 and the content screen of the operation display 2 have been switched by performing the cooperative effect on the cooperative effect display 4 as follows. For example, if the cooperative effect display 4 has an LED, the controller 24 may perform an effect such that light flows from a bottom to a top when the content screen of the distant display 7 is switched, and may perform an effect such that light flows from the top to the bottom when the content screen of the operation display 2 is switched. The controller 24 may perform the cooperative effect in a way other than the above-described example.

(2) Steering Switch Operation Determination Processing

The steering switch operation determination processing will be described with reference to FIGS. 14 to 17. When the controller 24 starts the steering switch operation determination processing, the controller 24 monitors whether the user has operated the steering switch 8 (S21 to S23). When the controller 24 receives the first start operation detection signal from the steering switch 8 and determines that the user has operated the steering switch 8 to start displaying the pop-up screen (S21: YES), the controller 24 outputs the pop-up screen control signal to the distant display 7 so that the distant display 7 starts display of the pop-up screen (S24).

When the controller 24 receives the first switching operation detection signal from the steering switch 8 and determines that the user has operated the steering switch 8 to switch the display of the pop-up screen (S22: YES), the controller 24 outputs the pop-up screen control signal to the distant display 7 so that the distant display 7 switches the display of the pop-up screen (S24).

When the controller 24 receives the first predetermined operation detection signal from the steering switch 8 and specifies that the user has operated the steering switch 8 to perform the predetermined operation for the predetermined item in the pop-up screen (S23: YES), the controller 24 outputs the pop-up screen control signal to the distant display 7 so that the distant display 7 updates the display of the predetermined item displayed on the pop-up screen according to the specified predetermined operation (S26). Furthermore, the controller 24 outputs the device control signal to the in-vehicle device to control the operation of the in-vehicle device according to the specified predetermined operation (S27).

The controller 24 determines whether the stop request for the vehicular display control system 15 has be generated (S28), and the above processing is repeated when the controller 24 determines that the stop request for the vehicular display control system 15 has not been generated (S28: NO). The controller 24 determines that the stop request for the vehicular display control system 15 has been generated (S28: YES), for example, when the ACC power supply is switched from on to off when the user gets off the vehicle, and ends the steering switch operation determination processing.

For example, as shown in FIG. 15, when the user operates the steering switch 8 to start displaying the pop-up screen from the state where the audio screen is displayed on the operation display 2 and the navigation screen is displayed on the distant display 7, the controller 24 instructs the distant display 7 to display a pop-up screen A1 capable of setting the air conditioner for the driver's seat.

Further, as shown in FIG. 16, when the user operates the steering switch 8 to switch the display of the pop-up screen from the state where the pop-up screen A1 capable of setting the air conditioner for the driver's seat is displayed, the controller 24 instructs the distant display 7 to switch the display from the pop-up screen A1 capable of setting the air conditioner for the driver's seat to a pop-up screen A2 capable of setting the air conditioner for the passenger's seat.

Further, as shown in FIG. 17, when the user operates the steering switch 8 to perform the temperature setting operation from the state where the pop-up screen A1 capable of setting the air conditioner for the driver's seat is displayed, the controller 24 instructs the distant display 7 to update the display of the temperature setting in the pop-up screen and controls the operation of the air conditioner device 33 according to the temperature setting operation. FIG. 17 illustrates a case where the display of the temperature setting is updated from “25.0” to “24.0” in response to the user operating the steering switch 8 to lower the temperature.

The controller 24 may set the pop-up screen that is displayed first immediately after the user operates the steering switch 8 to start displaying the pop-up screen to be a default pop-up screen or a pop-up screen displayed at the end of the previous time. That is, the pop-up screen is not limited to the temperature setting screen, but may be any screen such as a wind direction setting screen or an air volume setting screen. The controller 24 may delete the pop-up screen being displayed when the user operates the steering switch 8, or when an elapsed time from the start of the display reaches a predetermined time.

(3) Dial Operation Determination Processing

The dial operation determination processing will be described with reference to FIGS. 18 to 24. When the controller 24 starts the dial operation determination processing, the controller 24 monitors whether the user has operated the dial 12 (S31 to S33). When the controller 24 receives the second start operation detection signal from the dial 12 and determines that the user has operated the dial 12 to perform the display start operation of the pop-up screen (S31: YES), the controller 24 proceeds to display start control processing (S34).

When the controller 24 proceeds to the display start control processing, the controller 24 determines the sight line direction of the user at that time (S41, S42). When the controller 24 determines that the sight line direction of the user is in the direction of the distant display 7 (S41: YES), the controller 24 outputs the pop-up screen control signal to the distant display 7 so that the distant display 7 starts displaying the pop-up screen (S43). When the controller 24 determines that the sight line direction of the user is in the direction of the operation display 2 (S42: YES), the controller 24 outputs the pop-up screen control signal to the operation display 2 so that the operation display 2 starts displaying the pop-up screen (S44).

When the controller 24 receives the second switching operation detection signal from the dial 12 and determines that the user has operated the dial 12 to perform the display switching operation of the pop-up screen (S32: YES), the controller 24 proceeds to display switching control processing (S35).

When the controller 24 proceeds to the display switching control processing, the controller 24 determines whether the pop-up screen is being displayed on the operation display 2 or the distant display 7 at that time (S51, S52). When the controller 24 determines that the pop-up screen is being displayed on the distant display 7 at that time (S51: YES), the controller 24 outputs the pop-up screen control signal to the distant display 7 and switches the display of the pop-up screen on the distant display 7 (S53). When the controller 24 determines that the pop-up screen is being displayed on the operation display 2 at that time (S52: YES), the controller 24 outputs the pop-up screen control signal to the operation display 2 and switches the display of the pop-up screen on the operation display 2 (S54).

When the controller 24 receives the second predetermined operation detection signal from the dial 12 and determines that the user has operated the dial 12 to perform the predetermined operation for the predetermined item in the pop-up screen (S33: YES), the controller 24 proceeds to item control processing (S36).

When the controller 24 proceeds to the item control processing, the controller 24 determines whether the pop-up screen is being displayed on the operation display 2 or the distant display 7 at that time (S61, S62). When the controller 24 determines that the pop-up screen is being displayed on the distant display 7 at that time (S61: YES), the controller 24 outputs the pop-up screen control signal to the distant display 7 so that the distant display 7 updates the display of the predetermined item displayed on the pop-up screen (S63). Furthermore, the controller 24 outputs the device control signal to the in-vehicle device to control the operation of the in-vehicle device according to the specified predetermined operation (S64). When the controller 24 determines that the pop-up screen is being displayed on the operation display 2 at that time (S62: YES), the controller 24 outputs the pop-up screen control signal to the operation display 2 so that the operation display 2 updates the display of the predetermined item displayed on the operation display 2. Furthermore, the controller 24 outputs the device control signal to the in-vehicle device to control the operation of the in-vehicle device according to the specified predetermined operation (S66).

The controller 24 determines whether the stop request for the vehicular display control system 15 has be generated (S37), and the above processing is repeated when the controller 24 determines that the stop request for the vehicular display control system 15 has not been generated (S37: NO). The controller 24 determines that the stop request for the vehicular display control system 15 has been generated (S37: YES), for example, when the ACC power supply is switched from on to off when the user gets off the vehicle, and ends the dial operation determination processing.

For example, as shown in FIG. 22, when the user touches the dial 12 to start displaying the pop-up screen from the state where the audio screen is displayed on the operation display 2 and the navigation screen is displayed on the distant display 7, if the sight line direction of the user at that time is in the direction of the operation display 2, the controller 24 starts displaying a pop-up screen B1 capable of setting the air conditioner for the driver's seat on the operation display 2. On the other hand, if the sight line direction of the user at that time is in the direction of the distant display 7, the controller 24 starts displaying the pop-up screen A1 capable of setting the air conditioner for the driver's seat on the distant display 7 as shown in FIG. 15.

As shown in FIG. 23, when the user presses the dial 12 to switch the display of the pop-up screen from the state where the pop-up screen B1 capable of setting the air conditioner for the driver's seat is displayed, the controller 24 switches the display of the operation display 2 from the pop-up screen B1 capable of setting the air conditioner for the driver's seat to a pop-up screen B2 capable of setting the air conditioner for the passenger's seat, for example.

As shown in FIG. 24, when the user rotates the dial 12 to perform the temperature setting operation from the state where the pop-up screen B1 capable of setting the air conditioner for the driver's seat is displayed, the controller 24 updates the display of the temperature setting on the pop-up screen and controls the operation of the air conditioner device 33 according to the temperature setting operation. FIG. 24 illustrates a case where the temperature setting display is updated from “25.0” to “24.0” in response to the user rotating the dial 12 to lower the temperature.

Also in this case, the controller 24 may set the pop-up screen that is displayed first immediately after the user operates the dial 12 to start displaying the pop-up screen to be the default pop-up screen or the pop-up screen displayed at the end of the previous time. That is, the pop-up screen is not limited to the temperature setting screen, but may be any screen such as a wind direction setting screen or an air volume setting screen. The controller 24 may delete the pop-up screen being displayed when the user operates the dial 12, or when the elapsed time from the start of the display reaches the predetermined time.

The configuration for displaying the pop-up screen related to the air conditioner function has been exemplified above, but a configuration for displaying the pop-up screen related to the navigation function, the audio function, or the telephone function may also be employed. The contents to be displayed as the pop-up screen may be set by the user. Each time the user presses the dial 12, a setting item may be changed in the order of a temperature setting for the driver's seat, a wind direction setting for the driver's seat, an air volume setting for the driver's seat, a temperature setting for the passenger's seat, a wind direction setting for the passenger's seat, and an air volume setting of the passenger's seat, for example.

The configuration in which one dial 12 is provided has been exemplified above. However, for example, two dials may be arranged side by side in the left-right direction, and a dial for setting the temperature, the wind direction, and the air volume for the driver's seat, and a dial for setting the temperature, the wind direction, and the air volume for the passenger's seat may be independent from each other.

The configuration described in the present embodiment can provide advantages below. In the vehicular display control system 15, the screen switching operation of the operation display 2 and the distant display 7 can be performed by the user operating the operation display 2. When the screen switching operation of the operation display 2 by the user is accepted, the display of the content screen of the operation display 2 is switched, and when the screen switching operation of the distant display 7 by the user is accepted, the display of the content screen of the distant display 7 is switched. Accordingly, the user can appropriately switch the display of the content screens of both the operation display 2 and the remote display 7 without impairing the operability and safety. Further, since the display of the content screen of the distant display 7 can be switched by the user operating the operation display 2, it is possible to achieve both visibility during driving and operability at hand.

The operation performed by the user for the icons 11a to 11d is accepted as the screen switching operation. When the user operates the icons 11a to 11d, the user can appropriately switch the display of the content screens of the operation display 2 and the distant display 7.

The operation for switching the display of the content screen of the operation display 2 and the operation for switching the display of the content screen of the distant display 7 are different from each other. Therefore, the user can grasp the operation for switching the display of the content screen of the operation display 2 and the operation for switching the display of the content screen of the distant display 7 without confusion.

For example, the arc-shaped mark 41a is displayed on the upper portion of the icons 11a to 11d corresponding to the content screen displayed on the distant display 7, and the arc-shaped mark 41b is displayed on the lower portion of the icons 11a to 11d corresponding to the content screen displayed on the operation display 2. Based on the display mode of the icons 11a to 11d, the user can appropriately grasp the content screen displayed on the distant display 7 and the content screen displayed on the operation display 2.

When the user operates the steering switch 8, the display of the pop-up screen on the distant display 7 is started or switched, or the display of the predetermined item on the pop-up screen is updated and the operation of the in-vehicle device is controlled. Therefore, the user can appropriately perform various operations while ensuring visibility during driving.

When the user operates the dial 12, the display of the pop-up screen is started or switched, or the display of the predetermined item on the pop-up screen is updated on the operation display 2 or the distant display 7 according to the sight line direction of the user, and the operation of the in-vehicle device is performed. Therefore, the user can appropriately perform various operations according to the sight line direction of the user.
