Description

  The present invention relates to a vehicular information display device, and more particularly to a vehicular information display device capable of integrating and operating a plurality of in-vehicle devices and displaying information.

  2. Description of the Related Art In recent years, various devices such as a car navigation device, a traffic information display device, an air conditioner, an audio device, an e-mail and a telephone, and an internet connection device are mounted on a vehicle such as an automobile. If each of these devices is mounted separately and dedicated operation buttons, knobs, etc. are provided for each device, it will be necessary to place a large number of operation buttons, etc., of a large number of devices in a limited space in the passenger compartment. The operation buttons and the like have been downsized so that not only the operation of each device is difficult, but also an improvement has been demanded from the viewpoint of safety. In addition to the increase in system, this problem has become more prominent with the increase in functions given to the system.

  In order to solve this problem, in recent years, the system has been integrated and an operation switch corresponding to the activated system is displayed on the LCD screen, and various functions are executed by operating it. A system has been proposed. This makes it possible to secure a large screen because space can be used effectively, and only the necessary system switches can be placed and displayed on this screen, so the switch can be enlarged without sacrificing functions. Therefore, it has become possible to provide a high level of safety by reducing driver confirmation.

However, a new problem has been discovered when trying to add useful information and convenient functions for passengers. In other words, when the touch panel method is used, the switch for the active system can be laid out on a large screen, so it can be arranged with a certain amount of switch size, but the operation part is the same even if the system changes. There is a problem that it is difficult to remember the arrangement of the switch for each system, and unlike the hardware switch, it is not possible to get a tactile sensation etc. As the number of switches increases, the position of the switch can be remembered further There was a problem that it became difficult and eventually forced the driver to perform confirmation work, and it was difficult to increase the functions after all.
Therefore, the inventors of the present invention have found a concept in which the same operation is performed between systems in a system integrated to solve this problem. In other words, even if the system is switched, the switch arrangement will remain the same, that is, the same position will be maintained even if the system is switched by placing switches with the same function at the same position. It is thought that the driver can easily learn the switch arrangement because of the switch, and can reduce the driver's confirmation work and improve safety. In addition, in this case, when the operational feeling is unified in this way, the switch arrangement of the system with many functions is dragged to the system with few functions, and the hierarchy is higher than ever to cover the many functions. The problem of becoming deeper. In other words, although the position of the switch can be understood with a sense, it is faced with a new problem that it is very troublesome to display the switch of the necessary function because the hierarchy is deep. Because it is an integrated system, it must be operated many times from the top floor TOP screen to the level with the switch of the function that you want to operate every time there is an inevitable frequent movement between systems. It is a thing with the problem that switching will become a very painful state.

Next, details of selection of the operation screen by the operation screen selection means 30 will be described with reference to FIGS. FIG. 12 is a main flow of operation screen selection control by the operation screen selection means 30. FIG. 13 is a control flow of the process in step S2 of FIG.
In step S1 of FIG. 12, it is determined whether or not the system selector switch 12 is operated. When the system changeover switch 12 is not operated, one process of this control flow is terminated. When the system changeover switch 12 is operated, the process proceeds to step S2, and in step S2, a storage process for the final screen that is the operation screen displayed before the system changeover switch 12 is operated is performed. The final screen of each in-vehicle device is configured to be stored in a first memory (not shown) built in the integrated processing apparatus 10. Details of the processing in step S2 will be described later with reference to FIG. Next, in step S3, a system switching process corresponding to the operated system selector switch 12 is performed, and one process of this control flow is terminated. Details of the processing in step S3 will be described later with reference to FIG.

  Next, the details of the process in step S2 of FIG. 12 will be described with reference to FIGS. First, in step S21 of FIG. 13, it is determined whether or not the operation screen before the system changeover switch 12 is operated is the operation screen of the air conditioner 22. When the operation screen is the operation screen of the air conditioner 22, the process proceeds to step S24, it is determined not to store the screen as the final screen, and the process proceeds to step S25. Further, in step S25, if the final screen is stored in the first memory, it is deleted, and one process of this flowchart is terminated. As shown in FIG. 14, in the present embodiment, the air conditioner 22 can perform almost all operations that are commonly used on the uppermost operation screen, and the use frequency of operation screens other than the uppermost layer is very low. The final screen is not stored.

  On the other hand, when the operation screen before the system changeover switch 12 is operated is not the operation screen of the air conditioner 22, the process proceeds to step S22. In step S22, the operation end determination unit 30a of the operation screen selection unit 30 determines whether or not the operation on the operation screen before the system changeover switch 12 has been operated. When the operation end determination unit 30a determines that the operation screen is in the middle of operation, the operation screen is stored in the first memory as the final screen, and one process of this flowchart is ended. When the operation end determination unit 30a determines that the operation screen is not in the middle of operation, the process proceeds to step S24. In step S24 and subsequent steps, the above-described processing is performed, and the one-time processing of this flowchart is terminated. For example, the operation end determination unit 30a determines that the operation screen illustrated in FIG. 7B is being operated, and determines that the operation screen illustrated in FIG. 7E is not being operated.

Next, the system switching process in step S3 of the flowchart of FIG. 12 will be described with reference to FIGS. FIG. 15 is a flowchart showing details of the process in step S3 of the flowchart of FIG. FIG. 16 is a flowchart showing details of the process in step S33 of FIG. 15, and FIG. 17 is a flowchart showing details of the process in step S36 of FIG.
First, in step S31 of FIG. 12, it is determined to which in-vehicle device the system changeover switch 12 assigned has been operated. Next, in step S32, an in-vehicle device activation process corresponding to the operated system selector switch 12 is performed. Further, in step S33, it is determined whether or not the contents of the first memory in which the final screen of the in-vehicle device corresponding to the operated system changeover switch 12 is preferably displayed at the present time, If not, the contents of the first memory are erased. Details of the processing in step S33 will be described later with reference to the flowchart of FIG.

Next, in step S34, it is determined whether or not the final screen is stored in the first memory. When the first memory has a storage of the final screen of the in-vehicle device corresponding to the operated system changeover switch 12, the process proceeds to step S35, and the final screen stored in the first memory is displayed. Finish the flow process. On the other hand, when there is no storage of the final screen of the in-vehicle device corresponding to the operated system changeover switch 12 in the first memory, that is, when the storage of the final screen is deleted in step S33, and the processing in step S33 is performed. If no final screen has been stored before the process, the process proceeds to step S36.
In step S36, it is determined whether or not the preparation screen prepared for the in-vehicle device corresponding to the operated system changeover switch 12 is displayed. Details of the processing in step S36 will be described later with reference to the flowchart of FIG. If it is determined in step S36 that the preparation screen is to be displayed, it is determined in step S37 that the preparation screen display conditions are met. If it is determined that the preparation screen display condition is met, the process proceeds to step S39, the preparation screen prepared for the in-vehicle device corresponding to the operated system changeover switch 12 is displayed, and the processing of this control flow is terminated. .

  If it is determined in step S36 that the preparation screen is not displayed, it is determined in step S37 that the preparation screen display conditions are not met. If it is determined that the preparation screen display conditions are not met, the process proceeds to step S38, where the uppermost operation screen for the in-vehicle device corresponding to the operated system changeover switch 12 is displayed, and the processing of this control flow is terminated. .

Next, details of the process in step S33 of FIG. 15 will be described with reference to FIG. If the final screen is not stored in the first memory, no process is performed in step S33, and the process proceeds to the next step.
First, in step S41 of FIG. 16, it is determined whether or not the final screen of the in-vehicle device corresponding to the operated system changeover switch 12 stored in the first memory is new. That is, when 48 hours or more have elapsed since the last operation of the final screen, the process proceeds to step S44, and the final screen stored in the first memory is erased. This is because it is difficult for the user to continue the operation on the final screen that has passed two or more days after the user last operated. However, when the content of the final screen is the system setting screen, the user may continue the operation, and thus the storage in the first memory is not erased. FIG. 18 is an example of a system setting screen of the car navigation device 18. As shown in FIG. 18, the system setting screen is an operation screen related to the basic functions of the in-vehicle device such as the display image quality of the display, the brightness, the volume of the alarm sound, and the possibility of continuing the operation even after a lapse of time. In this case, the memory in the first memory is not erased.

  On the other hand, if 48 hours or more have not elapsed since the last operation on the final screen, the process proceeds to step S42. In step S42, after the final screen is last operated, it is determined by the occupant change determination unit 30b built in the operation screen selection means 30 whether or not the driver has been changed. In the present embodiment, the occupant change determination unit 30b determines whether or not there is a driver change based on the position setting of the driver seat. When there is no change of the driver, one process of this control flow is finished while leaving the storage in the first memory.

  If the driver is changed in step S42, the process proceeds to step S43. In step S43, it is determined whether or not the destination is set by the car navigation device 18. If the destination has been set by the car navigation device 18, the process proceeds to step S45. In step S45, the destination arrival determination unit 30c built in the operation screen selection means 30 determines whether or not the destination has already been reached. If it has not yet arrived at the set destination, it is determined that the driver has changed on the way to the destination even if there is a change in the driver, and the control flow One process is completed. On the other hand, if the destination has already been reached, the process proceeds to step S46. In step S46, the content of the final screen is determined, and if the final screen is the waypoint setting screen of the car navigation device 18, it is necessary to set a waypoint in the middle after having already arrived at the set destination. Since there is no, erase this. If the final screen is a screen other than the waypoint setting screen, the one-time processing of this control flow is terminated with the first memory remaining.

On the other hand, if it is determined in step S43 that the destination has not been set, the process proceeds to step S47. In step S47, it is determined whether or not the current position of the vehicle is around the home of the owner of the vehicle. In the present embodiment, the operation screen selection means 30 is configured so that the vehicle is in the vicinity of the home based on the information on the current position of the vehicle obtained by the car navigation device 18 and the home address information input in advance to the car navigation device 18. It is judged whether or not. When the current position of the vehicle is not around the house, even if there is a change in the driver, it is considered that the driver is temporarily changing on the way to a remote destination, so the first memory is stored. The one-time process of this control flow is terminated.
On the other hand, if it is determined in step S47 that the current position of the vehicle is around the home of the owner of the vehicle, the process proceeds to step S48, and the final screen stored in the first memory is erased. This is because there is a possibility that the driver is changed at the vehicle owner's home and is heading for another destination. However, when the content of the final screen is the system setting screen, the user may continue the operation, and thus the storage in the first memory is not erased.

  Through the control flow described above, the operation screen selection unit 30 selects an operation screen to be displayed when the system switch 12 is operated. Further, in the present embodiment, after the final screen is selected and displayed by the operation screen selection unit 30, the preparation screen is displayed by operating the system changeover switch 12 twice in a double click manner. It is configured to be able to. Alternatively, the preparation screen can be displayed when the top menu switch 14 is similarly operated.

Next, a forced display switching function of the vehicle information display device 1 according to the embodiment of the present invention will be described with reference to FIGS. 19 and 20.

In step S61 of FIG. 20, it is determined whether or not the vehicle is traveling. When the vehicle departs from the stopped state, the process proceeds to step S61. When the vehicle stops from the traveling state, the process proceeds to step S68. In step S61, it is determined whether or not the currently displayed operation screen is desirably displayed while the vehicle is traveling. In the present embodiment, an operation screen or the like that requests the driver to operate the screen keyboard is determined to be an operation screen that is not preferably displayed during traveling. If the currently displayed operation screen is an operation screen that does not cause any problem even if it is displayed during traveling, the one-time processing of this control flow is terminated without switching to the forced display screen.

  On the other hand, if the operation screen currently displayed is an operation screen that is not desired to be displayed during traveling, the process proceeds to step S63. In step S63, it is determined whether or not the currently displayed operation screen is a screen in the middle of an operation. In the present embodiment, the destination setting screen using the screen keyboard of the car navigation device 18, the e-mail input screen, and the like are determined to be mid-operation screens. If it is determined that the screen is in the middle of an operation, the process proceeds to step S64, the currently displayed operation screen in the middle of the operation is stored in the second memory, and the process proceeds to step S65. As described above, the second memory stores a screen in the middle of the operation forcibly switched by the forced screen selection unit 38.

  On the other hand, if it is determined in step S63 that the currently displayed operation screen is not a screen in the middle of operation, the process proceeds to step S65 without storing the operation screen. In step S65, it is determined whether or not the car navigation device 18 is activated. If the car navigation device 18 is activated, the process proceeds to step S66, and the map display screen (see FIG. 8) of the car navigation device 18 is selected as the forced display screen. On the other hand, if the car navigation device 18 is not activated in step S65, the process proceeds to step S67, and the operation screen of the audio device 20 is selected as the forced display screen.

  Next, a control flow when the vehicle stops from the traveling state will be described. When the vehicle is stopped from the traveling state, the process proceeds from step S61 to step S68. In step S68, it is determined whether or not a screen in the middle of an operation forcibly switched by the forced screen selection means 38 is stored in the second memory. If it is not stored in the second memory, the process proceeds to step S73. In step S73, the final screen stored in the first memory is selected as the forced display screen. On the other hand, if the screen during operation is stored in the second memory, the process proceeds to step S69.

  In step S <b> 69, when the operation screen stored in the second memory was previously displayed by forced display, it is determined whether the user has switched the operation screen using the system switch 12. When the operation screen of the second memory is displayed, if the user has switched to another operation screen by the system selector switch 12, the user does not want to display the operation screen of the second memory. Therefore, the stored contents of the second memory are erased and the process proceeds to step S73. In step S73, as described above, the final screen stored in the first memory is selected as the forced display screen.

  On the other hand, if it is determined in step S69 that the user has not switched to another operation screen for the operation screen in the second memory, the process proceeds to step S70. In step S70, when the operation screen stored in the second memory was previously displayed by forced display, it is determined whether or not the user has operated the operation screen. When the user performs an operation on the operation screen of the second memory, it is considered that the user desires an operation on the operation screen. Therefore, the process proceeds to step S71, and the contents of the second memory are stored in the second memory. Copy to 1 memory. As a result, when either the first memory screen or the second memory screen is selected, the operation screen is displayed. Next, the process proceeds to step S72, and the operation screen stored in the second memory is selected as the forced display screen.

On the other hand, if the user does not operate the operation screen of the second memory in step S70, the process proceeds to step S72 as it is, and the operation screen stored in the second memory is selected as the forced display screen. The In this case, thereafter, when the operation screen of the second memory is selected, the forced display screen is displayed, and when the operation screen of the first memory is selected, the final screen is displayed.
Next, in step S74, the forced display screen selected as the forced display screen in step S66, S67, S72, or S73 is displayed on the main monitor 2, and one process of this control flow is completed.
