JP 2001-33256 A (page 3-6, FIG. 1-8)

  By the way, in the vehicle-mounted electronic device disclosed in Patent Document 1 described above, the processing load of the control unit is increased because the processing of changing the contents of the display function and the operation function according to the traveling speed of the vehicle is performed. There was a problem. For example, when various image processing (for example, map drawing processing) is performed by the same control unit, the processing capability may not be sufficient, and therefore it is preferable that the processing load is as light as possible. Further, in the above-described in-vehicle electronic device, the contents of restrictions on the display function and the operation function change according to the traveling speed. However, the content change is not observed when the display unit is observed carefully or when the operation unit is operated. There was a problem that it was difficult to understand unless the reaction was observed closely. For example, the operation using each switch displayed on the screen is invalidated by the fact that there is no response after pressing these switches. And it is difficult to do accurately. In addition, it can be seen from the display screen after switching that the display content has been simplified according to the traveling speed, but it is not easy to see the display screen only for confirmation after starting the travel. There is also.

  The present invention was created in view of the above points, and its purpose is to restrict display functions and operation functions according to the running state while preventing an increase in processing load. An object of the present invention is to provide an in-vehicle device capable of easily confirming a restricted state.

In order to solve the above-described problem, an in-vehicle device according to the present invention includes a traveling state determination unit that determines a traveling state of a vehicle, a lid provided on the surface of the housing, and a lid that is in accordance with the determined traveling state. an opening and closing mechanism for opening and closing the parts, operation means for a simple operation portions corresponding to detail the operation portion and a closed state corresponding to the open state of the lid, be selectively exposed according to the opening and closing state of the lid, housing Display means provided on the surface of the body and at least partially shielded by the opening / closing operation of the lid, and the lid is closed when the running state determined by the running state judging means is running When the simple operation section is exposed and a part of the display means is shielded, and the traveling state determined by the traveling state determination means is stopped, the lid is opened and the detailed operation section is exposed. shielding of the display means with the Ru is released. The lid portion opens and closes according to the traveling state of the vehicle, and the detailed operation portion and the simple operation portion are switched. Therefore, the operation function can be limited according to the traveling state. In addition, since the contents of the operation unit itself are mechanically switched, it is possible to easily check the state in which the function is limited. Furthermore, since the switching of the operation function is performed simply by opening and closing the lid, complicated control is unnecessary, and an increase in processing load can be prevented.

Further, by further providing a display means provided on the surface of the housing described above and at least partially shielded by the opening / closing operation of the lid, the lid according to the running state is provided in parallel with the limitation of the operation function. The display function can be limited as the part is opened and closed.

  The simple operation unit described above is preferably switches or operation knobs that give the same operation instruction to a part of the detailed operation unit and have a large operation area. Accordingly, only large switches or operation knobs that are easy to operate can be used according to the traveling state, and the operation during traveling can be simplified. Further, by changing the size of the switches, it can be easily confirmed that the detailed operation unit has been switched to the simple operation unit.

  In addition, essential information that is indispensable when performing an operation instruction is displayed in the non-shielded area of the display unit described above, and additional information that is not essential when performing an operation instruction is displayed in the area that is shielded by the display means. It is desirable. As a result, it is possible to display only the minimum necessary information even during traveling, and it is possible to continuously perform necessary operation instructions.

  Moreover, it is preferable that the display of information in the non-shielded area of the display unit described above is performed using larger characters than the display of information in the shielded area of the display unit. As a result, it is possible to perform display that is easy to view even while traveling, and display of the minimum necessary information can be continued.

  Hereinafter, an in-vehicle device according to an embodiment to which the present invention is applied will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of an audio device as an in-vehicle device according to an embodiment. As shown in FIG. 1, the audio apparatus 100 of this embodiment includes a CD player 110, a tuner 112, an audio control unit 114, a digital-analog converter (D / A) 116, a speaker 118, a display unit 120, and a detailed operation unit. 122, a simple operation unit 124, a vehicle speed sensor 130, a traveling state determination unit 132, and a rotation drive unit 134.

  The CD player 110 plays a CD and outputs audio data. The tuner 112 receives AM and FM radio broadcasts and outputs audio data corresponding to the broadcast contents. The audio control unit 114 controls the reproduction operation by the CD player 110 and the reception operation by the tuner unit 112. For example, the audio control unit 114 gives instructions to start and stop playback of a CD loaded in the CD player 110, specify a track number to be played back, etc., and specify a broadcast station to be received by the tuner 112.

  The digital-analog converter 116 converts audio data output from the CD player 110 or the tuner 112 into an analog audio signal and outputs the analog audio signal from the speaker 118. Actually, a plurality of speakers 118 (for example, a total of six speakers in the case of 5.1 channel audio) are provided, and an amplifier is connected to the front stage of each speaker 118. In FIG. It is omitted.

  The display unit 120 displays information indicating the operation state of the CD player 110 and the tuner 112 and information necessary for each operation instruction.

  The detailed operation unit 122 is an operation unit for giving all possible operation instructions to the audio apparatus 100. In addition, the simple operation unit 124 is an operation unit for instructing the audio device 100 to perform a minimum necessary operation instruction. As the switches and operation knobs included in the simple operation unit 124, those having a small number and a large operation area are used. On the other hand, since the switches and operation knobs included in the detailed operation unit 122 are many, those having a small operation area are used. Each of the detailed operation unit 122 and the simple operation unit 124 is provided on both surfaces of an openable / closable lid 126 attached to the front surface of the housing of the audio apparatus 100. The detailed operation unit 122 can be operated with the lid 126 opened, and the simple operation unit 124 can be operated with the lid 126 closed.

  The vehicle speed sensor 130 detects the traveling speed of the vehicle on which the audio device 100 is mounted. For example, a vehicle speed pulse is output from the vehicle speed sensor 130 at every constant travel distance. The vehicle speed sensor 130 may be the one provided for the audio device 100 of the present embodiment. If the vehicle speed sensor 130 is already provided for a navigation device (not shown) or the like, the output thereof is provided. May be acquired and used.

  The traveling state determination unit 132 determines the traveling state of the vehicle according to the output state of the vehicle speed pulse from the vehicle speed sensor 130. For example, in the simplest case, it is determined whether the vehicle is running or stopped according to the presence or absence of a vehicle speed pulse.

  The rotation drive unit 134 opens and closes the lid 126 according to the vehicle traveling state determined by the traveling state determination unit 132. When it is determined whether the vehicle is running or stopped as the running state of the vehicle, the lid 126 is rotationally driven so as to be open when the vehicle is stopped, and the lid 126 is closed when the vehicle is running. It is rotationally driven so as to be in a state. For example, a shaft whose both ends are rotatably attached to a part of the housing is attached to the lower portion of the flat lid portion 126, and the entire lid portion 126 is centered on this shaft by a motor (not shown). The rotation drive unit 134 is configured to be rotatable. As long as the lid 126 can be opened and closed, the specific configuration of the rotation driving unit 134 may be any.

  The travel state determination unit 132 described above corresponds to the travel state determination unit, the rotation drive unit 134 corresponds to the opening / closing mechanism, both the detailed operation unit 122 and the simple operation unit 124 correspond to the operation unit, and the display unit 120 corresponds to the display unit.

  The audio apparatus 100 according to the present embodiment has such a configuration, and the operation thereof will be described next. FIG. 2 is a flowchart showing an operation procedure of the audio apparatus 100 that opens and closes the lid 126 according to the traveling state of the vehicle.

  When the ignition key of the vehicle is turned on and the operating voltage is supplied to the audio apparatus 100 and becomes operable, first, the traveling state determination unit 132 determines that the vehicle is stopped and determines to the rotation driving unit 134. In response, an instruction to open the lid 126 is sent. As a result, the rotational drive unit 134 is rotationally driven so that the lid 126 is opened (step 100).

  Thereafter, the traveling state determination unit 132 determines whether or not the vehicle has started traveling (step 101). If the vehicle is stopped, a negative determination is made and this determination is repeated. On the other hand, when the vehicle starts traveling, an affirmative determination is made in the determination of step 101, and then the traveling state determination unit 132 sends an instruction to close the lid 126 to the rotation driving unit 134. Thus, the lid 126 is rotated by the rotation driving unit 134 so as to be closed (step 102).

  Next, the traveling state determination unit 132 determines whether or not the vehicle has stopped traveling (step 103). If the vehicle is traveling, a negative determination is made, and this determination is repeated. On the other hand, when the vehicle stops traveling, an affirmative determination is made in the determination of step 103, and the operation after returning to step 100 to open the lid 126 is repeated.

  3 and 4 are diagrams illustrating the relationship between the open / closed state of the lid 126 and the operation unit and the display unit. In a state where the lid portion 126 is opened, the detailed operation portion 122 provided on one surface of the lid portion 126 appears at an operable position, as shown in FIG. In this state, the entire display unit 120 is exposed. The screen of the display unit 120 includes a simple display area 120A in the upper part and a detailed display area 120B in the lower part. In the simple display area 120A, essential information (essential information) for performing an operation instruction to the audio apparatus 100 is displayed, and in the detailed display area 120B, an operation instruction to the audio apparatus 100 is performed. Information that is not essential (additional information) is displayed. In addition, when various types of information displayed in the simple display area 120A and the detailed display area 120B are compared, the information displayed in the simple display area 120A uses larger characters.

  When the lid 126 is closed, as shown in FIG. 4, the simple operation unit 124 provided on the other surface of the lid 126 appears at an operable position. In this state, the detailed display area 120B included in the display unit 120 is shielded by the lid part 126, and only the display content of the simple display area 120A can be seen.

  As described above, the lid 126 opens and closes according to the running state of the vehicle, and the detailed operation unit 122 and the simple operation unit 124 are switched. Therefore, the operation function can be limited according to the running state. In addition, since the contents of the operation unit itself are mechanically switched, it is possible to easily check the state in which the function is limited. Furthermore, since the switching of the operation function is performed simply by opening and closing the lid portion 126, complicated control is unnecessary, and an increase in processing load can be prevented.

  In addition, the display unit 120 is provided on the surface of the housing of the audio device 100 and is at least partially shielded by the opening / closing operation of the lid 126, and in a running state in parallel with the limitation of the operation function. The display content can be limited with the opening and closing of the corresponding lid 126.

  In addition, the simple operation unit 124 includes switches or operation knobs that give the same operation instruction to a part of the detailed operation unit 122 and have a large operation area. Accordingly, only large switches or operation knobs that are easy to operate can be used according to the traveling state, and the operation during traveling can be simplified. In addition, by changing the size of the switches, it can be easily confirmed that the detailed operation unit 122 has been switched to the simple operation unit 124.

  In addition, in the simple display area 120A of the display unit 120 that is not shielded, essential information that is essential when performing an operation instruction is displayed, and in the detailed display area 120B that is shielded of the display unit 120, it is essential when performing an operation instruction. Since the additional information is not displayed, only the minimum necessary information can be displayed even while the vehicle is traveling, and the necessary operation instructions can be continuously given to the audio device 100. .

  In addition, since the information display in the simple display area 120A is performed using larger characters than the information display in the detail display area 120B, it is possible to perform display that is easy to view even while traveling. , The display of the minimum necessary information can be continued.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. In the above-described embodiment, the lid portion 126 is provided in the audio device 100. However, the lid portion is provided in another in-vehicle device, for example, a navigation device or an air conditioner, so that the operation unit and display contents at the time of stopping and running are displayed. May be switched.

  In the above-described embodiment, the operation unit and display content are switched between when the vehicle is stopped and when the vehicle is traveling. However, the operation unit and display content are different depending on whether the vehicle traveling speed is equal to or less than a predetermined value. May be switched.

  In the above-described embodiment, only the simple display area 120A of the display unit 120 is visible during traveling. However, in the case of an in-vehicle device whose display is not particularly important, the entire display unit 120 is shielded during traveling. Also good.

  In the above-described embodiment, the vehicle traveling state is determined using the vehicle speed sensor 130.
