Description

  The present invention relates to an in-vehicle apparatus that displays a captured image around a vehicle by an in-vehicle camera on a display unit.

  For in-vehicle devices that have a navigation function or a display function for images taken by an in-vehicle camera, the display unit with a display screen is stored in the storage position inside the instrument panel when not in use, and the use position outside the instrument panel when in use. There is a mobile type that moves up to. In such a mobile type, after the engine is started (or after the ACC switch is turned on), the display unit moves from the storage position in the instrument panel to the external use position automatically or by a button operation or the like. Since it takes about ˜3 seconds, for example, when the vehicle is moved backward immediately after the engine is started, it is not possible to display the rear shot image of the vehicle before starting the reverse drive.

  By the way, in order to keep the display unit standing up from the instrument panel while the occupant is in the vehicle, it is in the storage position in the instrument panel when door unlocking and door opening operations are detected. There has been proposed an in-car type device that starts up the display unit and protrudes from the upper surface of the instrument panel (see, for example, Patent Document 1).

Japanese Patent No. 3555371

  According to the in-car type device described in Patent Document 1 described above, it is possible to display a rear shot image of the vehicle photographed by the in-vehicle camera before starting the reverse movement even in the case of reverse movement immediately after the engine start. Even when the vehicle cannot be moved backward, the display unit always protrudes from the upper surface of the instrument panel due to detection of door unlocking and door opening operation, which may cause an undesired operation. .

  The present invention has been made in view of such circumstances, and after detecting the occupant's boarding on the vehicle, when the vehicle can be moved backward, the display unit in the storage position inside the instrument panel is placed outside the instrument panel. An object of the present invention is to provide an in-vehicle device that starts moving to a use position.

In order to solve the above problems, an in-vehicle apparatus according to the present invention is an in-vehicle apparatus having a display unit that displays an image and a display control unit that displays a captured image of the surroundings of the vehicle by the in-vehicle camera on the display unit. Boarding detection means for detecting boarding of the vehicle in the driver's seat, reverse drive detection means for detecting whether or not the vehicle is in a position where the vehicle can be moved backward, and the display portion within the instrument panel. And a display unit moving mechanism that moves between the instrument panel and a use position outside the instrument panel, the boarding detection means detects the boarding of the driver's seat of the vehicle, and the reverse possibility detection means moves backward with respect to the vehicle. Display unit movement control means for moving the display unit from the storage position to the use position by the display unit movement mechanism when it is detected that the display unit is at a possible position.

  According to such a configuration, when the boarding of the driver's seat of the vehicle is detected and it is detected that the vehicle is in a position where it can move backward, the display unit is moved from the storage position inside the instrument panel to the instrument panel. Compared with the conventional device that starts moving the display unit after the engine is started, the rear captured image is displayed on the display unit before starting the reverse movement even when the vehicle is moved backward immediately after the engine is started because it is moved to the external use position. It becomes possible. Further, even if it is detected that the vehicle is in the driver's seat, the display unit movement control means does not start moving the display unit from the storage position to the use position when it is detected that the vehicle is in a position where it cannot move backward. Occurrence of operation can be suppressed. In such a case, the display unit can be set to start moving from the storage position to the use position after the engine is started (or after the ACC switch is turned on).

  In the in-vehicle apparatus according to the present invention, the backward travelable detecting means can detect whether or not the vehicle is in a position where the vehicle can travel backward based on a rearward captured image of the vehicle by the in-vehicle camera.

  According to such a configuration, it is possible to detect whether or not the vehicle is in a position where the vehicle can be moved backward based on a rear image captured by the in-vehicle camera. Need not be provided separately. However, a sensor for detecting whether or not the vehicle is in a backward-movable position may be provided instead of or in addition to the detection of the backward-movable position based on the rear shot image. For example, an infrared sensor, an ultrasonic sensor, or the like can be provided in the vehicle as the detection sensor.

  In the vehicle-mounted device according to the present invention, the boarding detection means may be a boarding detection sensor that detects door unlocking from the outside of the driver's seat of the vehicle or door opening from the outside.

  According to such a configuration, the detection of the vehicle by detecting whether the vehicle can be driven backward by the vehicle reverse possibility detecting means and the door unlocking from the outside or the door opening from the outside, so even when the vehicle moves backward immediately after the engine starts, It is possible to move the display unit to the use position before starting the reverse drive and display the rear shot image of the in-vehicle camera.

  In the in-vehicle apparatus according to the present invention, the in-vehicle camera includes an internal in-vehicle camera that captures an image of the inside of the vehicle, and the boarding detection unit further includes the driver's seat based on a captured image inside the vehicle by the internal in-vehicle camera. It can be set as the structure which has an image boarding detection means which detects boarding.

  According to such a configuration, since the vehicle is detected based on the captured image inside the vehicle by the internal in-vehicle camera together with the detection of the vehicle reverse possibility by the vehicle reverse possibility detection means, even when the vehicle immediately reverses after starting the engine, It is possible to display a rear image captured by an in-vehicle camera that images the rear of the vehicle by moving the display unit to the use position before starting the reverse travel.

  The vehicle-mounted device according to the present invention has gear position detection means for detecting the gear position of the vehicle, and when the gear position detection means detects that the gear position is at a position for moving the vehicle backward, the display The control means may be configured to display a rear shot image of the vehicle by the in-vehicle camera on the display unit.

  According to such a configuration, when the gear position detecting unit detects that the gear position is in a position to move the vehicle backward, the rear shot image by the in-vehicle camera is displayed on the display unit. In this case, it is possible to display the rear shot image before starting the backward movement.

  In the in-vehicle device according to the present invention, the display unit movement control means, when the drive unit for running the vehicle within a predetermined time after the display unit is moved from the storage position to the use position does not operate. The display unit may be configured to move from the use position to the storage position.

  According to such a configuration, after the display unit is moved to the use position, when a drive unit (engine, motor, etc.) that runs the vehicle within a predetermined time does not operate, it corresponds to a case where the vehicle is not started. The display unit can be moved (returned) to the storage position. For example, when the forgotten item is returned to the vehicle, the display unit is returned from the use position to the storage position.

  According to the vehicle-mounted device according to the present invention, when the boarding of the driver's seat of the vehicle is detected and the vehicle is detected to be in a position where it can move backward, the display unit is moved from the storage position inside the instrument panel to the instrument. Since the vehicle is moved to a use position outside the panel, a rear shot image of the vehicle can be displayed on the display unit before the reverse is started even when the vehicle is moved backward immediately after the engine is started.

  Embodiments of the present invention will be described with reference to the drawings.

  The in-vehicle device according to the embodiment of the present invention is configured as shown in FIG.

  As illustrated in FIG. 1, the in-vehicle device 11 includes a processing unit 12 configured by computer units (for example, a CPU, a RAM, a ROM, an I / O interface, and a bus connecting them). Connected to the processing unit 12 are an AV unit 15 capable of reproducing various sound sources and video sources (for example, CD and DVD) and a navigation unit 17 capable of navigating the own vehicle. Further, a speaker 18 is connected to the processing unit 12 via an output circuit 19. As a result, the audio signal related to the processing by the AV unit 15 and the navigation unit 17 can be output as audio from the speaker 18 via the output circuit 19. In addition, the processing unit 12 can store various information such as music information and map information used in the AV unit 15 and the navigation unit 17 and a program or the like for exercising each function of the in-vehicle device 11 ( For example, a hard disk, a flash memory, etc.), a display unit 21 for displaying images, videos, etc. associated with various processes constituted by an LCD, etc., and instructions necessary for various processes provided on the display unit 21 by touch operation A touch panel 22 that can be input and an operation unit 23 that includes hard keys (physical keys) and that can input instructions necessary for various processes are connected. Furthermore, a plurality of in-vehicle cameras 29 for photographing the outer periphery of the vehicle and the inside of the vehicle including the driver's seat and displaying the photographed image on the display unit 21 are connected to the processing unit 12.

  The processing unit 12 includes at least a boarding detection sensor 27 (for example, a door unlocking detection sensor from outside and a door opening detection sensor from outside) that detects a boarding of the driver's seat from the outside. Either one can be used, but in this embodiment, the use of a door opening detection sensor will be described below), and a gear position detection sensor 28 for detecting the gear position of the vehicle is connected. The door unlocking detection sensor and the door opening detection sensor described above both detect the door unlocking and door opening by the occupant from the outside of the vehicle. In addition, it changes to the above-mentioned boarding detection sensor 27, and boarding to a driver's seat is detected based on the picked-up image of the vehicle-mounted camera 29 which image | photographs the inside of a vehicle (for example, based on the difference etc. with the imaging | photography image inside a normal vehicle). It is also possible (image boarding detection means). Further, the processing unit 12 includes a display unit moving mechanism 25 that moves the display unit 21 including the touch panel 22 between a storage position inside an instrument panel (not shown) and a use position outside the instrument panel. A drive circuit 26 that is driven under the control of the above is connected.

  The display unit moving mechanism 25 for moving the display unit 21 between the storage position inside the instrument panel and the use position outside the instrument panel is shown in FIG. 5 (showing the storage position) and FIG. This will be described with reference to (showing the use position).

  As shown in FIG. 5, when the in-vehicle device 11 is not used, the main body of the display unit 21 is instrumented so that the top of the display unit 21 is substantially flush with the instrument panel surface 31 (indicated by a chain line). It is stored in the storage position inside the panel. When the in-vehicle device 11 is used, as shown in FIG. 6, the processing unit 12 (display unit movement control means) moves the entire display unit 21 by the display unit moving mechanism 25 through the drive circuit 26 (see FIG. 1). It is moved to the use position so as to be exposed from 31, and after use, it is moved again to the storage position inside the instrument panel.

  The display unit moving mechanism 25 is provided in the instrument panel, and mainly includes a driving unit 35 including a driving motor 32, gear mechanism units 36a and 36b for converting the rotational motion of the driving unit 35 into a longitudinal motion and the like, Slide part 37a, 37b that moves up and down the display part 21, connecting parts 38a, 38b that connect the gear mechanism parts 36a, 36b and the slide parts 37a, 37b, and support legs that support the slide parts 37a, 37b in the vertical direction 41a and 41b. By such a display unit moving mechanism 25, the display unit 21 (including the touch panel 22) can move between a storage position inside the instrument panel and a use position outside the instrument panel.

  The on-vehicle device 11 having the above-described configuration is processed in a procedure as shown in FIG. In the description of the procedure shown in FIG. 2, FIG.

  As shown in FIGS. 2 and 1, the processing unit 12 detects the boarding of the vehicle (not shown) in the driver's seat by the boarding detection sensor 27 (S11: boarding detection means). The boarding detection sensor 27 in the present embodiment is a sensor that detects opening from the outside of the door of the driver's seat, but may be a sensor that detects unlocking from the outside of the door of the driver's seat, for example. Furthermore, the boarding of the driver's seat may be detected when both unlocking and door opening are detected. When the processing unit 12 detects the boarding of the driver's seat based on the detection signal from the boarding detection sensor 27 (YES in S11), the processing unit 12 turns on the vehicle-mounted camera 29 and starts the operation (S12).

  After the start of the operation of the in-vehicle camera 29, the processing unit 12 detects whether or not the vehicle can be moved backward based on the rear captured image of the vehicle captured by the in-vehicle camera 29 (S13: Reversed movement detecting means). When it is detected that the vehicle can move backward (YES in S13), it is considered that the vehicle may move backward (predictability), and the processing unit 12 causes the display unit moving mechanism 25 to place the display unit 21 in the storage position inside the instrument panel. Is started toward the use position outside the instrument panel (S14: display unit movement control means). When it is detected that the vehicle can be moved backward, it is assumed that the vehicle is going backward. In order to display the rear shot image on the display unit 21 before starting the backward movement, the display unit 21 starts moving from the storage position toward the use position. It is made to let you.

  The detection of whether or not the vehicle can be moved backward based on the back-captured image captured by the in-vehicle camera 29 is, for example, a method of performing a difference from the past back-captured image, a method of detecting an object based on edge information of the back-captured image, or a failure. This can be performed by using a method of obtaining the distance from the parallax of the same object captured in the right image and the left image acquired from the left and right cameras to the object. In addition, the detection of whether or not the vehicle can move backward is also targeted for the road surface condition in the backward direction in addition to the presence or absence of an obstacle. Further, in the present embodiment, whether or not the vehicle can be moved backward is detected based on the captured image of the in-vehicle camera 19, but it may be detected whether or not the vehicle can move backward using various sensors such as an infrared sensor.

  When it is not detected that the vehicle can move backward (NO in S13), the processing unit 12 does not start moving the display unit 21 from the storage position. When there is an obstacle behind the vehicle or when it is impossible to reverse, the display unit 21 is not moved at this timing because the vehicle is obviously not expected to reverse. When it is not detected that the vehicle can move backward (NO in S13), the processing unit 12 detects whether or not the engine is started (or the ACC switch is turned on) (S15), and the engine is started (or the ACC switch is turned on). Sometimes the display unit 21 is moved from the storage position toward the use position by the display unit moving mechanism 25 as usual set (S16), and a predetermined image can be displayed on the display unit 21 based on the setting or the occupant's operation. (S20: see later). When the movement of the display unit 21 is a manual operation, the display unit 21 can be moved from the storage position to the use position by the display unit moving mechanism 25 by an operation using an operation button or the like of the operation unit 23.

  As described above, after the vehicle is detected to be able to move backward (YES in S13) and the display unit 21 starts moving from the storage position toward the use position, the processing unit 12 starts the engine of the vehicle (or turns on the ACC switch). ) Is detected (S17). When the engine start (or the ACC switch is turned on) is not detected within a predetermined time (NO in S17), the processing unit 12 moves the display unit 21 from the use position toward the storage position (S26: display unit movement control). Means: see later). This is because the display unit 21 is returned to the storage position when the door is not opened, such as when the door is opened to collect forgotten items in the vehicle.

  After detecting engine start (or ACC switch ON) (YES in S17), the processing unit 12 has the vehicle gear position in the reverse position (back gear position) or the forward position (drive gear position, etc.). Is detected based on the detection signal of the gear position detection sensor 28 (S18: gear position detection means). When the processing unit 12 detects that the gear position is in the reverse position (detects the reverse position of the gear in S18), the processing unit 12 displays an image captured rearward of the vehicle by the in-vehicle camera 29 on the display unit 21 (S19: display unit control). means). As described above, since the display unit 21 has already started moving from the stowed position toward the use position by detecting the boarding of the driver's seat and the detection of the reverse drive of the vehicle, the subsequent engine start detection and the reverse gear position are detected. The rear shot image can be displayed on the display unit 21 before the vehicle starts moving backward after detection. Therefore, unlike the conventional vehicle-mounted device that starts moving the display unit from the storage position after the engine is started (after the ACC switch is turned on), according to the vehicle-mounted device 11 according to the present embodiment, even when the vehicle is moving backward immediately after the engine is started. Since the rear captured image can be displayed on the display unit 21 before the start, the rear of the vehicle can be confirmed by the captured image.

  When the processing unit 12 detects that the gear position of the vehicle is in the forward position (drive gear position or the like) (detects the forward position of the gear in S18), the processing unit 12 displays a predetermined image on the display unit 21 based on the setting. (S20). For example, the vehicle position in the navigation mode is displayed on a map.

  Further, as described above, the processing unit 12 displays the rear shot image on the display unit 21 (S19), and detects the display switching by the operation of the driver or the like (YES in S21), the display unit 21. The display on the screen is switched (S22). Even when a predetermined image is displayed on the display unit 21 (S20), when display switching due to an operation by the driver or the like is detected (YES in S23), the display on the screen of the display unit 21 is switched (S24). When the processing unit 12 detects the end of the operation of the in-vehicle device 11 (switch OFF or the like) (YES in S25), the display unit 21 is moved from the use position outside the instrument panel to the inside of the instrument panel by the display unit moving mechanism 25. Is moved toward the storage position (S26: display unit movement control means). Thereby, the display part 21 is accommodated in the instrument panel as shown in FIG.

  FIG. 4 shows a time-dependent movement state from the storage position of the display unit 21 of the in-vehicle device 11 according to this embodiment to the display position in comparison with a conventional in-vehicle device. In the conventional vehicle-mounted device, as shown in FIG. 4, immediately after the engine is started, the display unit starts moving from the storage position inside the instrument panel toward the use position outside the instrument panel, and after T seconds (about 2 to 3 The use position is reached in about a second). For this reason, when the vehicle moves backward immediately after the engine is started, the rear shot image of the vehicle by the vehicle-mounted camera cannot be displayed on the display unit before the vehicle starts moving backward, and the vehicle-mounted device cannot be used sufficiently.

  On the other hand, in the vehicle-mounted device 11 according to the present embodiment, the display unit 21 is moved from the storage position inside the instrument panel to the instrument panel by detecting boarding from the outside of the driver's seat door and detection of possible backward movement based on the rear shot image. The movement is started toward the use position outside the instrument panel, and the use position is reached after T seconds (about 2 to 3 seconds). As a result, compared to conventional in-vehicle devices, it reaches the use position earlier by a time difference ΔT (about 2 to 3 seconds), so even if the vehicle goes backward immediately after the engine starts, It is possible to display on the display unit 21 and to move backward while confirming the rear part with an image. When the vehicle is parked and it is clearly determined that it is impossible to move backward, the operation of starting movement of the display unit 21 is detected even when the vehicle-mounted device 11 according to the present embodiment detects boarding and can move backward. Can be set in advance.

  As described above, the on-vehicle device according to the present invention detects the boarding of the vehicle at the driver's seat and detects that the vehicle can move backward, and moves the display unit from the storage position inside the instrument panel to the outside of the instrument panel. Even if the vehicle is moved backward immediately after the engine is started, it is possible to display a rear shot image on the display unit before starting the reverse drive, and an image taken by the in-vehicle camera is displayed on the display unit. It is useful as an in-vehicle device.
