  The navigation device 3 includes a display/operation input unit 30 that displays guidance information and the like when operated by an occupant. The navigation device 3 is provided in the center of the dashboard on the front side in the vehicle compartment 200. The navigation device 3 can normally operate the display/operation input unit 30 while the driver 10 is sitting in the driver's seat 1, and can operate the display/operation input unit 30 while the passenger 20 is sitting in the passenger seat 2. It is provided in an operable position.

  The occupant sensor 4 detects movement of an occupant while the vehicle is traveling. The occupant sensor 4 includes an imaging unit 40. The occupant sensor 4 is provided above the navigation device 3. The occupant sensor 4 is provided at a position where the driver 10, the passenger 20, and the navigation device 3 can be monitored. A range R1 below the broken line in FIG. 1 is a range in which the occupant sensor 4 can monitor.

  An ECU 5 and a vehicle speed sensor 6 are provided outside the vehicle interior 200. The ECU 5 can communicate with the navigation device 3, the occupant sensor 4, and the vehicle speed sensor 6 through an in-vehicle network such as a CAN (Controller Area Network).

  FIG. 2 is a block diagram showing the configuration of an accessory device control system 100 for a vehicle.

  The navigation device 3 includes a display/operation input unit 30, a position information acquisition unit 31, a storage unit 32, a navigation control unit 33, and a communication unit 34.

  The display/operation input unit 30 has a function as a display unit, and the display/operation input unit 30 displays guidance information and the like. The guidance information includes a map showing the current position of the vehicle and the position of the destination, and information for guiding the driver 10.

  Further, the display/operation input unit 30 has a function as an operation input unit capable of performing various input operations on the navigation device 3. The display/operation input unit 30 is, for example, a touch panel.

  Here, the navigation device 3 has been described as having the display/operation input unit 30 having both the display function and the input function, but the display unit having the display function and the operation input unit having the operation input function are separately provided. You may have it. In that case, the operation input unit may be fixed to any position in the vehicle interior 200.

  The position information acquisition unit 31 acquires information on the current position of the vehicle based on the GPS (Global Positioning System) function provided in the vehicle.

  The storage unit 32 stores data necessary for forming guide information such as map information, a control program for controlling the navigation device 3, and the like.

  The navigation control unit 33 mainly executes the following functions in the present embodiment by executing a control program for controlling the navigation device 3 stored in the storage unit 32.

[Display control function]
The navigation control unit 33 controls the navigation device 3 based on the input from the display/operation input unit 30. For example, when the destination is set by the input from the display/operation input unit 30, the navigation control unit 33 stores the information on the current position of the vehicle acquired by the position information acquisition unit 31, the information on the set destination, and the storage. Guide information is formed based on the map information and the like stored in the unit 32. Then, the navigation control unit 33 displays the formed guidance information on the display/operation input unit 30.

[Operation restriction function]
Upon receiving the input restriction signal, the navigation control unit 33 restricts the operation of the navigation device 3 by the operation of the display/operation input unit 30. To limit the operation means to put the navigation control unit 33 into a state in which the input from the display/operation input unit 30 is not accepted. The input restriction signal will be described in detail later.

[Restriction release function]
The navigation control unit 33 releases the restriction of the operation of the navigation device 3 by the operation of the display/operation input unit 30 when the restriction release signal is received while the operation of the navigation device 3 is restricted. Releasing the restriction means that the navigation control unit 33 is in a state of receiving an input from the display/operation input unit 30. The restriction release signal will be described later in detail.

  The communication unit 34 is responsible for communication between the navigation device 3 and the ECU 5.

  The occupant sensor 4 includes an imaging unit 40, an imaging control unit 41, a storage unit 42, a determination unit 43, and a communication unit 44.

  The image capturing unit 40 captures an image in the vehicle interior 200 under the control of an image capturing control unit 41 described later.

  The image capturing section 40 may be a camera having an image sensor having sensitivity in the near infrared wavelength range and an illumination capable of emitting near infrared light. Further, the image capturing section 40 may be a camera that captures an image by the TOF (Time Of Flight) method, or a camera used in driver monitor technology.

  By using a camera having a sensitivity in the near-infrared wavelength region as the imaging unit 40, it becomes easy to detect the motion of the occupant even at night.

  When receiving the image pickup start signal, the image pickup control unit 41 causes the image pickup unit 40 to execute an image pickup operation. On the other hand, when the imaging control unit 41 receives the imaging stop signal, the imaging control unit 41 causes the imaging unit 40 to stop the imaging operation. The image capturing start signal and the image capturing stop signal will be described in detail later.

  The storage unit 42 stores a program relating to control of the occupant sensor 4, information necessary for detecting the occupant and each part of the occupant's body (arms, hands, fingers, etc.). The information necessary for detecting the occupant and each part of the occupant's body includes, for example, information such as data used for pattern matching and skeleton detection.

  The determination unit 43 detects the occupant and each part of the occupant's body based on the data of the image captured by the imaging unit 40 and the data stored in the storage unit 42. In addition, the determination unit 43 determines whether the detected motion of the occupant corresponds to a predetermined motion, based on the data of the plurality of images continuously captured by the imaging unit 40.

  The predetermined operation is an operation performed immediately before the occupant operates the display/operation input unit 30. Specifically, in the predetermined motion, a part of the occupant's body moves from the driver's seat 1 side toward the display/operation input unit 30 (first motion), and a part of the occupant's body is in the driver's seat 1 An operation (second operation) from the seat side other than toward the display/operation input unit 30 is included. Here, a part of the body includes an occupant's arm, hand, finger, and the like. The seats other than the driver's seat 1 include a passenger seat 2 shown in FIG. 1 and a rear seat (not shown).

  When determining that the detected motion corresponds to the second motion, the determination unit 43 transmits a passenger motion detection signal to the ECU 5. On the other hand, when the determination unit 43 determines that the detected motion corresponds to the first motion, it does not transmit the passenger motion detection signal. The passenger motion detection signal will be described in detail later.

  Further, the determination unit 43 determines whether or not the occupant has separated a part of his/her body from the display/operation input unit 30 by a predetermined distance or more. The determination unit 43 transmits an operation end signal to the ECU 5 when the occupant separates a part of his/her body from the display/operation input unit 30 by a predetermined distance or more. The operation end signal will be described in detail later.

  The communication unit 44 is responsible for communication between the occupant sensor 4 and the ECU 5.

  The occupant sensor 4 includes a CPU. The storage unit 42 also includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The CPU reads a program related to the control of the occupant sensor 4 from the ROM, expands the program in the RAM, and the CPU executes the expanded program, whereby the CPU functions as the imaging control unit 41, the determination unit 43, and the communication unit 44.

  The ECU 5 includes a CPU and a memory including a ROM and a RAM. The CPU functions as the control unit 50 and the communication unit 51 by reading the control program stored in the ROM, loading the control program in the RAM, and executing the loaded program.

[Driving state detection function]
The control unit 50 compares the vehicle speed detected by the vehicle speed sensor 6 with a predetermined threshold value to determine the traveling state of the vehicle. The threshold value is stored in a memory (not shown) in the ECU 5.

[Navigation device 3 control function]
The control unit 50 transmits an input restriction signal to the navigation device 3 when the vehicle starts traveling. Further, when the operation end signal is received from the occupant sensor 4, the input restriction signal is transmitted to the navigation device 3.

  The control unit 50 transmits a restriction release signal to the navigation device 3 when the vehicle stops. In addition, when the control unit 50 receives the passenger movement signal from the occupant sensor 4, the control unit 50 transmits a restriction release signal to the navigation device 3.

[Passenger sensor 4 control function]
The control unit 50 transmits an imaging start signal to the occupant sensor 4 when the vehicle starts traveling. On the other hand, when the vehicle has stopped, the control unit 50 sends an image pickup stop signal to the occupant sensor 4.

  The communication unit 51 is responsible for communication with the navigation device 3, the occupant sensor 4, and the vehicle speed sensor 6.

  The vehicle speed sensor 6 detects the vehicle speed. The vehicle speed sensor 6 also transmits a signal including information on the detected vehicle speed value to the ECU 5.

  FIG. 3 is a flowchart showing the operation of the vehicle accessory control system 100.

  First, when the vehicle engine is started, the vehicle speed sensor 6 detects the vehicle speed (step S1). Then, the vehicle speed sensor 6 transmits a signal including information on the detected vehicle speed to the ECU 5.

  Next, when the ECU 5 receives the signal from the vehicle speed sensor 6, the ECU 5 reads a predetermined threshold value from the memory of the ECU 5, and compares the value of the vehicle speed with the read predetermined threshold value (step S2). Here, the threshold value is, for example, 0 km/h. However, the threshold does not necessarily have to be 0 km/h.

  The case where the value of the vehicle speed is equal to or lower than the threshold value as a result of the comparison (No in step S2) will be described later.

  As a result of the comparison, when the value of the vehicle speed is larger than the threshold value (Yes in step S2), the ECU 5 determines whether the operation of the navigation device 3 is restricted (step S3). At this time, for example, the ECU 5 transmits a signal for confirming whether or not the operation of the navigation device 3 is restricted to the navigation device 3, and whether the operation is restricted based on the response from the navigation device 3. Determine whether or not. Alternatively, the ECU 5 determines whether or not the operation is restricted depending on the presence or absence of the log that the input restriction signal described later is transmitted to the navigation device 3.

  When the operation of the navigation device 3 is restricted (Yes in step S3), the process proceeds to step S6.

  When the operation of the navigation device 3 is not restricted (No in step S3), the ECU 5 sends an input restriction signal to the navigation device 3. The input restriction signal is a signal for causing the navigation device 3 to restrict the input from the display/operation input unit 30.

  Upon receiving the input restriction signal from the ECU 5, the navigation device 3 restricts the operation of the navigation device 3 by the operation of the display/operation input unit 30 (step S4). Note that, through steps S1 to S4, while the vehicle is traveling, the navigation device 3 is basically in a state where the operation is restricted.

  Next, the imaging unit 40 starts monitoring the range of R1 shown in FIG. 1 in the vehicle interior 200 (step S5). More specifically, the ECU 5 transmits an image pickup start signal to the occupant sensor 4. Then, when the occupant sensor 4 receives the imaging start signal from the ECU 5, the occupant sensor 4 causes the imaging unit 40 to perform an imaging operation. The image capturing start signal is a signal for causing the occupant sensor 4 to start capturing an image of an occupant in the passenger compartment 200. The data of the images captured by the image capturing unit 40 are sequentially transmitted to the determining unit 43.

  During monitoring in the vehicle interior 200, the determination unit 43 detects the occupant and each part of the occupant's body based on the image data captured by the image capturing unit 40. At this time, the determination unit 43 detects the occupant and each part of the occupant's body by, for example, skeleton detection and pattern matching.

  Next, the determination unit 43 determines whether or not the occupant's hand is moving toward the display/operation input unit 30 (step S6). Here, the determination unit 43 detects the motion of the occupant's hand based on the data of the plurality of images continuously captured by the imaging unit 40, and whether the detected motion of the occupant's hand corresponds to a predetermined motion. Determine whether or not.

  When the movement of the occupant's hand toward the display/operation input unit 30 is not detected (No in step S6), the operation of the accessory device control system 100 moves to step S1.

  When the motion of the occupant's hand toward the display/operation input unit 30 is detected (Yes in step S6), the determination unit 43 determines whether the detected motion is a predetermined motion by the driver 10. Yes (step S7). At this time, the determination unit 43 determines whether the occupant's hand is heading toward the display/operation input unit 30 to determine whether the detected predetermined motion is the motion by the driver 10 (first motion). It is determined whether the operation is performed by the person 20 (second operation).

  In order to distinguish the first motion and the second motion, the position information of the driver's seat 1 and the display/operation input unit 30 in the vehicle interior 200 may be stored in the storage unit 42 in advance. Based on the positional relationship between the driver's seat 1 and the display/operation input unit 30, the determination unit 43 determines whether a part of the occupant's body is approaching the display/operation input unit 30 from the driver's seat 1 side or other than the driver's seat 1. It is possible to distinguish whether the display/operation input unit 30 is approaching from the seat side of. The method of distinguishing the first motion and the second motion is not limited to this. For example, the position of the driver's seat 1 and the display/operation input unit 30 can be determined by detecting the positions of the steering wheel, the seat, and the display/operation input unit 30 in the passenger compartment 200 while the passenger compartment 200 is being monitored. The relationship may be determined, and the first action and the second action may be distinguished based on the determination result.

  As shown in FIG. 4, when the driver 10 brings his/her hand close to the display/operation input unit 30, the determination unit 43 detects the motion of the occupant's hand as the motion by the driver 10 (first motion). (Yes in step S7). At this time, the determination unit 43 does not transmit the fellow passenger detection signal to the ECU 5, and thus the restriction on the operation of the navigation device 3 is still maintained. Therefore, as shown in FIG. 4, the driver 10 cannot operate the navigation device 3.

  Thereafter, the operation of the accessory device control system 100 moves to step S1.

  On the other hand, as shown in FIG. 5, when the passenger 20 brings his/her hand close to the display/operation input unit 30, the determination unit 43 determines that the detected motion of the passenger is the motion by the passenger (second motion). It is determined (No in step S7). At this time, the determination unit 43 transmits a passenger detection signal to the ECU 5. The fellow passenger detection signal is a signal for notifying the ECU 5 that the fellow passenger is about to operate the display/operation input unit 30, and serves as a trigger for canceling the operation restriction of the navigation device 3.

  When the ECU 5 receives the passenger detection signal, the ECU 5 transmits a restriction release signal to the navigation device 3. The restriction release signal is a signal for releasing the restriction on the input from the display/operation input unit 30 of the navigation device 3.

  Upon receiving the restriction release signal, the navigation control unit 33 releases the restriction on the operation of the navigation device 3 (step S8). As a result, the navigation device 3 is in a state of being able to receive an input from the display/operation input unit 30. Therefore, as shown in FIG. 5, the passenger 20 can operate the navigation device 3.

  When the passenger 20 operates the display/operation input unit 30, the navigation control unit 33 accepts an input from the display/operation input unit 30, and controls the navigation device 3 according to the input (step S9).

  Next, the determination unit 43 determines whether the hand of the passenger 20 is separated from the display/operation input unit 30 by a predetermined distance or more (step S10). At this time, the determination unit 43 determines whether or not the occupant's hand is separated from the display/operation input unit 30 by a predetermined distance or more based on the data of the plurality of images continuously captured by the imaging unit 40. The value of the predetermined distance is stored in the storage unit 42.

  When the occupant's hand is not separated from the display/operation input unit 30 by the predetermined distance or more (No in step S10), the operation of the accessory device control system 100 proceeds to step S9. At this time, the determination unit 43 does not transmit the operation end signal. Therefore, the restriction on the operation of the navigation device 3 is still released.

  Therefore, the passenger 20 can continue to operate the navigation device 3 through the operation of the display/operation input unit 30.

  When the occupant's hand is separated from the display/operation input unit 30 by a predetermined distance or more (Yes in step S10), the determination unit 43 transmits an operation end signal to the ECU 5. The operation end signal is a signal for notifying that the desired operation of the navigation device 3 by the passenger 20 is completed. Then, when the operation end signal is received, the ECU 5 transmits the input restriction signal to the navigation device 3.

  Upon receiving the input restriction signal, the navigation controller 33 restricts the operation of the navigation device 3 (step S11).

  As a result of comparing the vehicle speed value and the threshold value, when the vehicle speed value is equal to or less than the threshold value (No in step S2), the ECU 5 determines whether the operation of the navigation device 3 is restricted (step S12). ).

  If the operation of the navigation device 3 is not restricted (No in step S12), the operation of the accessory device control system 100 ends. The occupant can continue to operate the navigation device 3 freely.

  When the operation of the navigation device 3 is restricted (Yes in step S12), the navigation control unit 33 releases the restriction of the operation of the navigation device 3 (step S13). At this time, the ECU 5 transmits a restriction release signal to the navigation device 3. Then, when the navigation control unit 33 receives the restriction release signal, the navigation control section 33 releases the restriction on the operation of the navigation device 3. This release operation allows the occupant to freely operate the navigation device 3.

  Further, the imaging unit 40 stops monitoring inside the vehicle interior 200 (step S14). Specifically, the ECU 5 sends an image pickup stop signal to the occupant sensor 4. Then, when the occupant sensor 4 receives the imaging stop signal from the ECU 5, the occupant sensor 4 stops the imaging operation of the imaging unit 40. The image capturing stop signal is a signal for causing the occupant sensor 4 to stop capturing an image of the occupant in the passenger compartment 200.

  Then, the operation of the accessory device control system 100 ends.

  When both the first motion and the second motion are detected by the occupant sensor 4, the passenger motion detection signal is not transmitted from the occupant sensor 4 to the ECU 5, and the restriction on the operation of the navigation device 3 is not released. That is, the operation restriction of the navigation device 3 is released only when the occupant sensor 4 detects the second motion and does not detect the first motion.

  If the driver's 10 hand approaches the display/operation input unit 30 while the passenger 20's hand is located near the display/operation input unit 30 while the vehicle is traveling, the accessory device control system 100 Detects the motion (first motion) of the driver 10. Then, the accessory device control system 100 restricts the operation of the navigation device 3.

  When the operation of the navigation device 3 is not restricted while the vehicle is traveling, if the operation of the driver 10 cannot be detected due to a malfunction of the occupant sensor 4, the operation of the navigation device 3 by the driver 10 cannot be restricted. .. However, according to the present embodiment, the operation of the navigation device 3 is restricted while the vehicle is traveling, and the operation of the navigation device 3 is restricted only when the passenger 20 tries to operate the display/operation input unit 30. To be released. Therefore, even if the occupant sensor 4 fails, the driver 10 can be surely prevented from operating the navigation device 3. Of course, even if the occupant sensor 4 fails, the operation restriction of the navigation device 3 is released when the vehicle stops (step S13), so that the occupant can operate the navigation device 3.

  Further, the range R1 that can be monitored by the occupant sensor 4 does not necessarily have to be the area including the occupant and the display/operation input unit 30 at all times, and may be at least the vicinity of the display/operation input unit 30. If the vicinity of the display/operation input unit 30 is included in the range R1, the occupant sensor 4 can detect an operation in the vicinity of the display/operation input unit 30 of the occupant, and thus the occupant's display/operation input unit 30 is operated. This is because it is possible to detect the action immediately before the action.

  The image capturing unit 40 may be a camera having a narrow image capturing range as long as it can monitor the operation of the occupant in the vicinity of the display/operation input unit 30, and the installation position of the occupant sensor 4 is not particularly limited.

  In the present embodiment, the imaging unit 40 monitors the inside of the vehicle compartment 200 while the vehicle is traveling, but it may be constantly monitored regardless of whether the vehicle is traveling.

  Further, in the present embodiment, the description has been made assuming that the accessory device is the navigation device 3, but this embodiment can be similarly applied even if the accessory device is another device such as a television.

  Further, in the present embodiment, the occupant sensor 4 is a sensor of a type that recognizes an image, but as long as it can detect a motion of the occupant who attempts to operate the display/operation input unit 30, it is a sensor of another type. Good. For example, the occupant sensor 4 may be a type of sensor that detects radio waves. In this case, two types of detected objects that can be mounted on the occupant's hands and emit different radio waves, and an element capable of detecting the radio waves from the detected object (hereinafter, radio wave detection element) are used. If the radio wave detection element is provided in the vicinity of the display/operation input unit 30, it can be detected that an object to be detected mounted on the occupant's hand approaches the display/operation input unit 30. Further, it is possible to distinguish which hand of the driver 10 and the passenger 20 approaches the display/operation input unit 30 based on the type of the detected radio wave.

  In the present embodiment, the operation of the navigation device 3 is basically limited, and the operation limitation is lifted when a specific condition is satisfied, but the present invention is not limited to this. That is, the operation is basically not limited, and the operation may be limited when a specific condition is satisfied. For example, the operation of the navigation device 3 is not restricted while the vehicle is traveling, and the operation of the navigation device 3 is detected when the movement of a part of the body of the driver 10 toward the display/operation input unit 30 is detected. You may be limited.

  As described above, the movement of a part of the body of the occupant of the vehicle is detected while the vehicle equipped with the accessory device is running. If the detected motion is the first motion from the driver's seat side toward the display/operation input unit, the input from the display/operation input unit is not accepted. If the detected motion is the second motion from the seat side other than the driver's seat toward the display/operation input unit, the input from the display/operation input unit is accepted. As a result, while the vehicle is traveling, the passenger can perform all operations of the accessory device without restriction, and thus the inconvenience of using the function of the accessory device for the occupant while the vehicle is traveling can be eliminated. . In addition, since the restriction on the operation of the accessory device for only the passenger is released, the driver's careless driving can be prevented.

  In addition, when both the passenger and the driver try to operate the display/operation input unit, in order to maintain the limitation of the operation of the accessory device, the driver must be sure to operate the accessory device while the vehicle is traveling. You can prevent it.

(Second embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIG. In the embodiments to be described below, the parts having the same effects as those of the above-described first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. In the following description, the first embodiment will be described. Differences from the form will be mainly described.

  FIG. 6 is a diagram showing a vehicle equipped with an accessory device control system 100 for a vehicle according to a second embodiment of the present invention.

  The vehicle accessory control system 100 according to the second embodiment includes an input terminal 35. The input terminal 35 is a remote controller for operating the navigation device 3. The occupant can operate the navigation device 3 by operating the input terminal 35. In FIG. 6, the input terminal 35 is located between the driver's seat 1 and the passenger seat 2, but the input terminal 35 is not fixed at a specific position in the vehicle interior 200.

  In the present embodiment, the occupant sensor 4 detects the movement of the occupant and the position of the input terminal 35. Since the input terminal 35 may be located anywhere in the passenger compartment 200, the occupant sensor 4 is provided at a position where it is possible to image the passenger compartment 200 in a wide range.

  Based on the positional relationship between the input terminal 35 and the driver's seat 1, the occupant sensor 4 performs a predetermined operation of the occupant such that a part of the occupant's body moves from the driver's seat 1 side to the input terminal 35 or other than the driver's seat 1. It is determined whether a part of the body of the occupant moves from the seat side of the vehicle to the input terminal 35. This determines whether the driver 10 is trying to operate the navigation device 3 or the passenger 20 is trying to operate it.

  Based on the determination result, the accessory device control system 100 maintains or releases the restriction on the operation of the navigation device 3 using the input terminal 35. In addition, the operation of the vehicle accessory control system 100 according to the second embodiment is the same as that of the vehicle accessory control system 100 according to the first embodiment.
