Description

The present invention relates to an input / output control device that controls input / output of an in-vehicle device, and particularly to an input / output control device that realizes appropriate input / output control for a driver and a non-driver.

Conventionally, an in-vehicle display device that performs display output of images and videos to vehicle occupants has been used. This in-vehicle display device has been adopted for the purpose of use in route guidance of the host vehicle, but in recent years, not only route guidance but also other uses, for example, an in-vehicle television device as disclosed in Patent Document 1 It is also used as display means for audio devices, DVD playback devices, and the like.

As the usage application of the in-vehicle display device expands in this way, the users targeted for display output are also changing. In other words, when used for route guidance, the user is mainly a driver, but in the display output of a TV or the like, a passenger (non-driver) seated in a passenger seat or rear seat becomes a user. There is a case.

Here, the display output for the driver needs to be performed within a range that does not impede the driving operation, and it is not preferable to perform television output or DVD reproduction while the vehicle is running.

It is also a feature that the display suitable for each other (except the driver's seat) is controlled and displayed. For example, for a movie or the like, display on the driver's seat side is prohibited, and display on the passenger seat side is possible. Therefore, inclusive of these, in the multi-display, only the operation reception or display for the driver's seat is limited to contents suitable for driving, and the operation reception or display for other than the driver's seat is limited in this way. Do not.

Hereinafter, an in-vehicle device which is a preferred embodiment of an input / output control device according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram showing a schematic configuration of an in-vehicle device 1 which is an embodiment of the present invention. As shown in the figure, the in-vehicle device 1 includes a main control unit 11, a navigation unit 12, and an A inside.
A V (audio / visual) unit 13, an operation input receiving unit 21, a vehicle speed sensor 22, a transmission mechanism state detection unit 23, a brake state detection unit 24, a display processing unit 31, a sound processing unit 32, a display 41, and a speaker 42 are provided.

The operation input receiving unit 21 is a processing unit that receives an operation input from an occupant using a switch, a touch panel, or the like, and includes an operator identification unit 21a therein. The operator identifying unit 21a identifies whether the operation input is performed from the driver's seat side (that is, by the driver) or from the passenger seat side (that is, by the non-driver).

The vehicle speed sensor 22 is a sensor that detects the traveling speed of the host vehicle from the tire rotation speed of the host vehicle, and the transmission mechanism state detector 23 is a sensor that acquires the state of the transmission mechanism of the host vehicle. Moreover, the brake state detection part 24 is a sensor which detects the operation state of the braking mechanism of the own vehicle.

The navigation unit 12 is a unit that sets and guides the travel route of the host vehicle. Specifically, the navigation unit 12 is a GPS (Global Positioning Sys
tem), the current position of the host vehicle is acquired, the road on which the host vehicle is traveling is specified using the map data, and the route guidance is executed using the display 41 and the speaker 42.

The AV unit 13 is a unit that provides content data acquired by reception of radio broadcasts, television broadcasts, and the like and content data read from recording media such as CDs, DVDs, and HDs to vehicle occupants. Here, the AV unit 13 includes an audio function 13a, a DVD playback function 13b, and a game function 13c.

The speaker 42 is a device that outputs sound to the occupant, and the output content is created by the sound processing unit 32. The display 41 is a device that performs display output for the occupant. The display content is created by the display processing unit 31.

Here, the display processing unit 31 includes a driver seat side display control unit 31 a and a passenger seat side display control unit 31.
b. The driver side display control unit 31 a is a processing unit that creates a display screen for the driver on the display 41, and the passenger seat side display control unit 31 b is a processing unit that creates a display screen for the non-driver on the display 41. It is.

A driver display screen and a non-driver display screen can be individually created on the single display 41 by the driver seat side display control unit 31a and the passenger seat side display control unit 31b.

The method for individually displaying the driver screen and the non-driver screen on the single display 41 is “a method of dividing the display screen and displaying each screen (FIG. 2-1)”, There is “a method of displaying a plurality of screens in an overlapping manner using the difference in the sight line direction of the passenger (FIG. 2-2)”. In the present embodiment, a case where a single display is used will be described as an example. However, dedicated displays may be provided for drivers and non-drivers, respectively.

The main control unit 11 is a control unit that controls the vehicle-mounted device 1 as a whole. The main control unit 11 receives inputs from the operation input receiving unit 21, the vehicle speed sensor, the transmission state detecting unit 23, and the brake state detecting unit 24, and the navigation unit 12 and the AV. The operation of the unit 13 is controlled and output to the display 41 and the speaker 42 via the display processing unit 31 and the audio processing unit 32.

The main control unit 11 includes a driver input / output control unit 11a and a non-driver input / output control unit 11b. The driver input / output control unit 11a is a control unit that controls reception of an operation input from the driver and output to the driver, and the non-driver input / output control unit 11b is a non-driver (in this embodiment). It is a control part which controls reception of the operation input from the passenger | crew who seated in the passenger seat, and the output to a non-driver | operator.

By the driver input / output control unit 11a and the non-driver input / output control unit 11b, the main control unit 11 can individually control input / output for the driver and input / output for the non-driver.

For example, when the host vehicle is running, the driver input / output control unit 11a restricts input / output that requires complicated operations such as setting of a destination by the driver and a gaze on the screen. The person input / output control unit 11b does not perform such a restriction. Therefore, the destination setting while the vehicle is traveling is accepted only from the passenger seat side.

Here, whether or not the host vehicle is traveling depends on the traveling speed of the host vehicle acquired by the vehicle speed sensor 22 and the state of the shift lever acquired by the transmission state detection unit 23 (the lever is “parking” or “
It is possible to determine whether the vehicle is in the “neutral” state, the brake state acquired by the brake state detection unit 24 (whether the parking brake is operating), or the like.

In addition, information related to the traveling of the host vehicle, for example, traffic information such as occurrence of traffic congestion, guidance output by the navigation unit 12, and video output around the host vehicle are important information for the driver, but are important for the non-driver. Is relatively low. Therefore, when the necessity of outputting information related to traveling occurs, the driver input / output control unit 11a preferentially outputs by interrupt processing, but the non-driver input / output control unit 11b does not perform interrupt processing.

The processing operation of the main control unit 11 will be described with reference to FIG. The flowchart shown in the figure is a process that is repeatedly executed during the operation of the in-vehicle device 1. First, the main control unit 11
Based on the input from the vehicle speed sensor 22, the transmission state detection unit 23, and the brake state detection unit 24, it is determined whether or not the host vehicle is traveling (step S101).

As a result, if the host vehicle is not running (step S101, No), the main control unit 11
Next, it is determined whether or not the driver side display control unit 31a and the passenger seat side display control unit 31b are displaying the same screen (step S102), and if the same screen is being displayed (step S102). S102, Yes), single operation control, that is, the same operation control is performed for the driver and the non-driver (step S103), and the process is terminated.

On the other hand, when the host vehicle is running (step S101, Yes), or when the display screen at that time is different (step S102, No), the main control unit 11 performs individual operation control,
That is, different operation control is performed for the driver and the non-driver (step S104), and the process ends.

Next, specific examples of individual operation control by the driver input / output control unit 11a and the non-driver input / output control unit 11b will be described. FIG. 4 is an explanatory diagram illustrating operation control on the passenger seat side (for non-drivers) and the driver seat side (for drivers).

As shown in the figure, for the navigation function, all operations are accepted on the passenger seat side. However, on the driver's seat side, when the host vehicle is running, operation restriction, for example, restriction of setting a destination or prohibiting various searches is performed.

Further, on the driver's seat side, when an operation is performed from the passenger seat side, a display for notifying the driver that there has been an operation input (display of the passenger seat operation) is performed. Further, for example, when a destination is set from the passenger seat side, a final confirmation operation for determining whether or not to register the destination is performed from the driver seat side (confirmation of the passenger seat operation).

In this way, it is possible to perform complicated operations such as destination setting only from the passenger seat side, notify the driver seat side of the occurrence of operation input, and confirm the operation content, so that the driver and the non-driver Can be used to perform a complex operation of the navigation function without obstructing the driving operation.

Further, as operation control on the driver's seat side, information related to driving (for example, VI
Traffic information acquired by CS etc., guidance screen at the time of route guidance, corner monitor that displays the image of the side of the vehicle, back monitor that displays the image of the back of the vehicle, etc. Control that promptly recognizes the information to be performed is performed.

Similarly, for the audio function, all operations are accepted on the passenger seat side, but on the driver's seat side, complicated operations such as editing the title of content data, such as editing the title of content data, are required when the host vehicle is running Restrict input and output.

As for the DVD playback function, the passenger seat side permits the function, that is, the DVD playback, but the driver seat side does not permit the playback. Similarly, for the game function, passenger side,
That is, the game content is provided to the non-driver, but the game content is not provided to the driver's seat side, that is, the driver.

It should be noted that operations from non-drivers such as the passenger seat can also be restricted. This limitation may be the entire operation range (operation type), or a part thereof may be selectively limited. Further, for example, a person sitting in the passenger seat can be identified, and a limit range can be set for the person. In other words, the limit range may be set such that the operation is accepted if the passenger seat is an adult and the operation is prohibited if the child is a child.

Furthermore, the operation range on the passenger seat side can be set based on the traveling state. For example, if the vehicle is traveling on a relatively long straight road at a stable speed, the destination setting from the passenger seat side is permitted, and on roads with continuous curves such as mountain roads, operation can be performed even from the passenger seat side. Restrict,
Such processing may be performed.

In addition, regarding the operation restriction on the driver side, it is not always necessary to perform the control in two stages of “running” and “stopping”, and the operation restriction is variably controlled depending on the running speed and the shape of the road being run. May be.

Further, the prohibition of DVD playback or the provision of a game function to the driver is limited to when the vehicle is running or the like, and may be executed while the vehicle is stopped or prohibited regardless of whether the vehicle is traveling or stopped. The function and the game function may be functions limited to non-drivers.

Next, a specific example of the display screen displayed on the display 41 will be described. FIG. 5 is a specific example of a display screen in the case where the operation restriction for the driver is performed. When stopped, the passenger ’s seat (
The display screen for P seat) and the display screen for driver seat (D seat) each display virtual operation buttons using a touch panel in addition to a map display.

However, when driving, the operation button on the passenger seat side is continuously displayed on the passenger seat side (the operation is also possible, for example, when the “spot registration button” is pressed, the screen shifts to the “search / setting screen”. However, the display of the operation button is erased on the display screen on the driver's seat side so that the operation by the driver is not performed. Here, instead of erasing the operation button, the display state of the operation button may be changed, for example, toned down so that it can be visually confirmed that the operation is being restricted.

In addition, the operation button is displayed, and when it is operated, the setting screen is displayed. However, the input operation after that is prohibited, or when it is operated, the operation is being restricted and a notification is given by display or sound. It is also good.

In FIG. 5, the case where different maps respectively designated on the passenger seat side and the driver side are displayed has been described as an example, but the same applies when the same screen is being displayed. Needless to say, control can be executed.

Next, FIG. 6 shows a display example when the driver's operation on the passenger seat is displayed and the details of the operation are confirmed. As shown in the figure, when the “spot registration button” is pressed on the passenger seat side, a notification message “Destination is being set for the P seat” is displayed on the display screen on the driver seat side. Also,
When the destination entry on the passenger side is completed, a confirmation message “Set destination at P seat. Are you sure?” And a confirmation input from the driver (see the figure) Then, “YES” button) is displayed.

Next, a specific example of the interrupt display for the driver will be described with reference to FIGS.
7 and 8, the same screen (audio reproduction screen) is displayed on the passenger seat (P seat) side and the driver seat (D seat) side, respectively.

When the necessity of guidance display occurs due to the traveling of the vehicle, guidance display is performed only on the driver's seat side as shown in FIG. 7, and the original audio screen is restored when the guidance is completed. Similarly, if there is a need to display an image behind the vehicle, for example when the vehicle is moving backwards,
As shown in FIG. 8, an image behind the vehicle is displayed only on the driver's seat, and the original audio screen is restored at the end of reverse travel.

In this way, interrupt indications related to driving operations are given only to the driver, and by continuing the original display for non-drivers such as passengers on the passenger seat, each of the driver and non-driver Optimal display can be performed.

As described above, in the in-vehicle device according to the present embodiment, the driver input / output control unit 11a and the driver input / output control unit 11b are adapted to the traveling speed of the host vehicle, the state of the transmission, the state of the brake, and the like. Based on this, the input / output for the driver and the input / output for the non-driver are individually controlled, so that appropriate input / output control can be realized for each.

As described above, the input / output control device according to the present invention is useful for input / output control of an in-vehicle device, and is suitable for input / output control when different outputs are given to a driver and a non-driver.
