Has been proposed. As described above, if the operation is locked while the vehicle is running in consideration of safety, passengers in the front passenger seat and rear seat will not be able to access the internet, and the convenience of the passenger will be reduced. A bad system.

 Conversely, if the driver is permitted to operate while driving, the driver may operate while driving, which may lead to an accident due to carelessness in the front. In view of this, Patent Document 2 proposes a configuration in which the first monitor installed in the driver's seat is turned off when the vehicle is running, and can be used in the second monitor installed in the rear seat side. Has been. Further, in Patent Document 3, the functions available in the front unit installed on the driver's seat side and the rear unit installed on the rear seat side are distributed, and the retuning function is also used on the front unit when the vehicle stops. A configuration has been proposed that allows this.

 However, the configurations described in Patent Literature 2 and Patent Literature 3 require a unit installed on the driver's seat side and a unit installed on another seat side, and the device configuration is complicated. It is difficult to reduce the cost.

The information includes (1) sound source direction information, (2) operation information, (3) biological information,着 The seating position can be specified based on the position information of the operation unit, and ⑤ other information.

 (1) The sound source direction information is effective when the input unit 11 is configured to accept an instruction input by an operator's voice. For example, a microphone array consisting of at least two or more microphones is installed inside the vehicle. It can be configured to determine the sound source direction information of the voice input as an instruction based on the time difference and the volume difference of the voice arrival, and to specify the seating position of the operator.

 (2) The operation information can be configured to constantly photograph the inside of the vehicle with a CCD camera or the like, monitor the image of the moving body, and identify the operator's seating position by image processing. When the input unit 11 is configured by a voice input unit that receives an instruction input by the voice of the operator, it may be configured to specify the seating position of the operator by voice authentication. Also

Instead of position detection based on images taken with CCD cameras, pyroelectric sensors and their A plurality of other human body sensors can be installed, and the seating position of the operator can be specified based on the detection signals of these sensors.

 ③ The biometric information is, for example, fingerprints, palm prints, voice prints, irises, retinas, vein patterns, and other biometric information that can identify the operator are registered in advance in association with the sitting position, and the operation is performed. By comparing with the biological information of the operator who performed or the operator who is going to perform the operation, it is possible to configure to specify the seating position of the operator. For example, an operation button equipped with a fingerprint sensor is provided as the input unit 11, and when the operator operates this operation button, the fingerprint information is detected and compared with the fingerprint information registered in advance, and the operator is seated. It can be configured to specify a position. Further, when the input unit 11 is configured to receive an instruction input by voice from the operator, the seating position is specified from voice information such as a voiceprint of the operator. Also in this case, the voice information such as the voiceprint of each passenger is registered in advance in association with the seating position.

 さ せ A password is registered for each passenger in association with the seating position, and when the operator inputs an instruction using the input unit 11, the operator is required to input the password to detect the seating position of the operator. It becomes possible. When a remote controller is used as the input unit 11 of the in-vehicle information processing device 1, it is possible to identify the operator's seating position by setting a password unique to each operator in advance. Become.

 The authentication unit 17 accepts registration of biometric information, a personal identification number, and the like for each occupant, and obtains biometric information and information of an operator who has performed an instruction input through the input unit 11 or an operator who intends to perform the instruction input. It obtains a password and collates it with pre-registered information.

 The control unit 10 controls the input unit 11, the output unit 12, the communication unit 13, and the position detection unit 15 so as to appropriately provide the service desired by the operator based on the instruction input by the operator. , And control so that the coordination of the content section 16 etc. is performed smoothly.

Further, the control unit 10 is configured to regulate an instruction input from the operator to the input unit 11 and an information output to the output unit 12 according to the running state of the vehicle and the seating position of the operator. You You. For example, when the vehicle information acquired by the vehicle monitoring unit 14 is in a traveling state, when it is determined that the operator who performed the operation or the operator who is going to perform the operation is sitting in the driver's seat, In order to ensure the safety of the system, the input from the operator is limited to voice input, and the information output to the operator is limited to voice guidance. Along with the restrictions on the input unit 11 and the output unit 12, it is possible to limit the services provided from the content unit 16. For example, if the vehicle information obtained by the vehicle monitoring unit 14 is a running state and the operator's seating position detected by the position detection unit 15 is the driver's seat, the operation and display of the TV It is configured to limit If the position detector 15 determines that the operator is sitting in the passenger seat, it determines that there is no problem with safety regardless of whether the vehicle is running or not. Therefore, it is possible to provide a service desired by the operator without limiting any of the input unit 11 and the output unit 12.

 With such a configuration, all the passengers including the driver are to be operated, and it is determined in which position in the vehicle the operator is seated, and the control of the instruction input and information output according to the seating position is performed. By limiting the services provided, it is possible to improve the convenience and operability of each operator while ensuring safety, and to realize a comfortable interface.

 First embodiment>

 The operation of the first embodiment of the present invention will be described based on a flowchart shown in FIG. The configuration of this embodiment is based on the configuration of FIG. 1 described in the schematic configuration described above. The input unit 11 includes two input means of a voice input unit and a touch panel input unit, and the output unit 12 As a configuration, the system is provided with two output units, an audio output unit and a monitor for displaying images. Further, the vehicle monitoring unit 14 is configured to detect whether or not the vehicle is running, for example, based on whether or not the vehicle speed information obtained from the acceleration sensor or the vehicle is “で”. .

 When the power is turned on and operation starts, initialization processing is performed in step S1 "I by resetting various parameters.

In step S12, it is determined whether or not an instruction input to input unit 11 has been received. Here, a voice input unit is provided as the input unit 11, and the voice input by the operator is used. It is determined whether or not the instruction input has been performed. If it is determined that the instruction input has been performed, the process proceeds to step S13.

 In step S13, the position detection unit 15 detects the seating position of the operator. The position detection unit 15 can be configured to provide a microphone array including at least two microphones, for example, and to detect the direction of a sound source based on voice data picked up by the microphone array. For example, as shown in Fig. 3, a microphone 51 for the driver's seat and a microphone 52 for the passenger's seat are installed in the driver's seat and the passenger's seat, respectively, and the sound data of the microphones 51, 52 are used to detect the sound source direction detecting means 5 3 To be entered. The sound source direction detection means 53 compares the level of the audio signal input from each of the driver side microphone 51 and the passenger side microphone 52 to determine whether the sound source direction is the driver side or the passenger side. Separately, the operator's seating position information is output. By installing microphone phones at each seat position in the vehicle, it is possible to identify an operator who is sitting in the rear seat other than the driver's seat and the passenger seat, for example. In addition, by using a delay-and-sum type microphone array that narrows the directivity in the target direction and emphasizes the target sound, and a blind-spot control type microphone array that forms a directional blind spot in the direction in which the sound is to be muted, y There is no need to install a microphone in the seat. For example, by arranging a microphone in the room mirror, the direction of the sound source can be specified.

 In step S14, it is determined whether the operator's seating position detected by the position detection unit 15 is the driver's seat. If it is determined that the operator's seating position is the driver's seat, the process proceeds to step S15, and if not, the process proceeds to step S18.

 In step S15, vehicle information on the running state of the vehicle is obtained. Here, vehicle speed data obtained from an acceleration sensor or a vehicle is obtained, and vehicle information indicating whether the vehicle is stopped or running is obtained.

 In step S16, it is determined whether or not the vehicle is running based on the obtained vehicle information. When it is determined that the vehicle is running, the process proceeds to step S17, and otherwise, the process proceeds to step S19.

In step S17, the restriction pattern 1 relating to the operations of the input unit 11, the output unit 12 and the content unit 16 is executed. Here, the operator's seating position is the driver's seat. Since the vehicle is running, the input section should be considered in consideration of the safety and convenience of the driver.

The instruction input to 11 is limited to only the instruction input by voice, and the information output from the output unit 12 is limited to only the audio output. Further, the content section 16 can be configured to prohibit a television receiver, a DVD player, an Internet access function involving image output, and the like. Thereafter, the flow shifts to step S2 "I, where the content section 16 executes content processing based on the instruction input.

 In step S18, it is determined whether or not the operator is seated on the passenger seat. If it is determined that the operator's seating position is the passenger's seat, the flow shifts to step S19, and if not, the flow shifts to step S20.

In step S19, the restriction pattern 2 relating to the operations of the input unit 11, the output unit 12, and the content unit 16 is executed. If the operator is seated in the front passenger seat, it is considered that the safety of the vehicle while traveling is not hindered. Therefore, regardless of whether the vehicle is traveling or not, the input unit 11, It can be set so that no restrictions are imposed on the output section 12 and the content section 16 at all. For example, when a touch panel input unit is provided as the input unit 11 as in this embodiment, an operator who is seated in the passenger seat even while traveling is allowed to input an instruction from the touch panel input unit. . In addition, for TV broadcasting, DVD players, or Internet access processing involving image processing, operations by the operator sitting in the passenger seat are permitted. As a result, the convenience and operability of the passenger sitting in the passenger seat can be improved by removing restrictions on the operation. Thereafter, the process proceeds to step S21, and the content section 16 executes content processing based on the instruction input. In step S20, the restriction pattern 3 relating to the operations of the input unit 11, the output unit 12, and the content unit 16 is executed. Here, the operator is seated on the rear seat because the operator's seating position is neither the driver's seat nor the passenger's seat. This in-vehicle information processing device 1 is supposed to be installed on the front panel in the vehicle, and if a touch panel input unit or the like is operated while leaning out from the rear seat, it will hinder the driving operation of the driver. There is a danger that it may hinder safe driving. In addition, children sitting in child seats in the backseat cannot operate the touch panel because they cannot touch the touch panel. Therefore, if the operator If it is determined that the instruction is input, the instruction input to the input unit 11 is limited to only the instruction input by voice. The information output from the output unit 12 can be set to be unrestricted regardless of whether the vehicle is running. In addition, the content section 16 can be set so that one navigation function cannot be operated. By setting such a restriction pattern 3, it is possible to maintain safety while the vehicle is running and to improve convenience for passengers who cannot physically operate the touch panel input unit and the like.

 <Another configuration example of the position detection unit>

 ① Authentication information

 A case will be described in which the authentication unit 17 executes authentication processing using biometric information and a password.

 In order to perform the authentication process in the authentication unit 17 and specify the seating position of the operator, it is necessary to previously store the occupant authentication information and the seating position in association with each other. After the initial settings at startup, the process shown in Fig. 4 is executed.

 In step S31, it is determined whether to register authentication information. For example, an instruction as to whether or not to register the authentication information by a menu display on a display panel constituting the output unit 12 is received. If there is an instruction to perform authentication information registration processing, the flow shifts to step S32.

 In step S32, an authentication information acquisition process is performed. For example, a fingerprint sensor is provided in the input unit 11, and fingerprint data of each passenger is obtained using the fingerprint sensor. The seating position of the occupant is input in association with the fingerprint data acquired by the fingerprint sensor. The authentication information can be, in addition to fingerprint data, a palm print, a voice print, an iris, a retina, a vein pattern, other biometric information, or a password set by each passenger.

 In step S33, the input authentication information is stored in a predetermined storage area of the control unit 10 in association with the occupant's seating position.

When an instruction is input to the input unit 11, fingerprint data of the operator is acquired by a fingerprint sensor provided in the input unit 11, and the fingerprint data is collated with authentication information stored in a predetermined area. However, it is possible to specify the seating position of the operator. If the authentication information is voiceprint data, iris data, vein pattern, etc., the biometric information of the operator who has input the instruction using the corresponding sensor is acquired, and verification with the registered authentication information is performed. Can be configured to do so. If the authentication information is a password, the password input via the input unit 11 is compared with the stored authentication information stored in advance to determine the seating position of the operator. Can be configured to be specified.

 ② Combination of sound source direction and biological information

 As shown in Fig. 5, a fingerprint sensor 62 is installed on the operation panel 61 set as the input unit 111, and fingerprint information acquired by the fingerprint sensor 62 is re-fingerprinted by the fingerprint authentication means 63. It is composed. A microphone 51 for the driver's seat and a microphone 52 for the passenger's seat are installed in the driver's seat and the passenger's seat, respectively, and the sound data of each microphone 51, 52 is input to the sound source direction detecting means 53. are doing.

 In this case, the fingerprint data of the passenger is acquired in advance and registered in association with the age of each passenger, the presence or absence of a driver's license, and other personal information related to this control.

 Every time the operator operates the operation panel 61, the fingerprint authentication unit 63 performs fingerprint collation based on the fingerprint data acquired by the fingerprint sensor 62, and the personal information of the corresponding operator is controlled by the control unit 110. Output to Further, the microphone / mouth phone arrays 51 and 52 provided as the position detection unit 15 and the sound source direction detection means 53 detect the direction of the sound source of the operator, identify the operator's seating position, and specify the operator's seating position. The information is configured to be output to the control unit 10.

 Existing car navigation voice input methods are often configured to press a button and then speak in order to accurately determine the operator's utterance start position. In this voice input method, by adopting the present embodiment, the control unit 10 can identify who the operator is in addition to the seating position of the operator. The most suitable input / output interface and contents can be provided based on the seating position, the age of the operator, the presence or absence of a driver's license, and other personal information.

In this case, as described above, it is not necessary to associate and register the fingerprint data and the corresponding seating position of the passenger, and even if the seating position is changed during traveling, the seating position is detected. It is possible to leave.

 ③ Image processing

 If a touch panel or a button provided near the front panel in the car is prepared as the input unit 11, a CCD camera that monitors the moving body near this input unit 11 is installed, and the image of this CCD camera is used. It can be configured to detect the sitting position of the operator.

 For example, as shown in FIG. 6, a camera 71 is installed on a button installed on a touch panel or a front panel of the in-vehicle information processing device 1, and motion detection means 72 to which image information of the camera 71 is input is used. It can be configured to detect the movement of the hand that operates the touch panel or the button, and detect the operator's seating position.

 The simplest algorithm for motion detection is to compare the feature values (color information, luminance information, etc.) of each pixel unit between frames, and to determine which pixels have a large amount of change in a moving area and which pixels with a small amount of change will be static. The area is determined. Of these, the moving area is determined as a hand movement, and if the direction of arrival of the hand is determined to be either the driver's seat or the passenger's seat, the operator's seating position can be detected. .

The seating position of the operator is rear seat it is also possible to detect from the image information of the camera 71, it is possible to correspond to the case by ¹ ^ of variously adjusting the algorithm of motion detection .

 ④Infrared sensor

 As described above, when a button provided near the touch panel or the front panel in the vehicle is provided as the input unit 11, infrared sensors are arranged on both sides of the input unit 11, and the touch panel or the button is provided. It can be configured to detect the movement of the operating hand to detect the seating position of the operator.

For example, as shown in Fig. 7, near the operation panel 81, a pyroelectric infrared sensor (hereinafter referred to as a pyroelectric sensor) that detects the proximity of a heat source, converts it to a voltage level, and outputs the voltage level is output. , 83 3 is installed. Here, a first pyroelectric sensor 82 is provided on the driver's seat side of the operation panel 81, and a second pyroelectric sensor 83 is provided on the passenger's seat side of the operation panel 81. The detection signals of the two pyroelectric sensors 82, 83 are input to the operation detecting means 84. The operation detecting means 84 is based on detection signals from the two pyroelectric sensors 82 and 83. Thus, it is possible to determine whether the direction of arrival of the hand operating the operation panel 81 is the driver's seat side or the passenger's seat side, and specify the seating position of the operator.

 操作 Operation buttons corresponding to seats

 An operation button can be provided corresponding to each seating position in the vehicle, and the operator's seating position can be detected based on which operation button is operated.
