Description

  The present invention relates to an information processing device for a vehicle, an information processing system for a vehicle, and an information processing program for a vehicle that perform an operation on an operated device existing inside the vehicle.

  2. Description of the Related Art Conventionally, as an information processing apparatus that operates an operation target without using a controller, a technique that uses an operator's fingers as an operation object is known. For example, the device described in Patent Document 1 performs an operation on an operation target such as a home television set. When a gesture with an operator's finger is recognized, an operation corresponding to the gesture is performed.

  In an information processing apparatus that operates an operation target by recognizing a gesture with a finger in this way, when the operator moves the finger instead of intending to perform the operation, the movement of the finger is detected and the operation target is detected. There is a problem of executing the operation. Therefore, there is a demand for an information processing apparatus that can prevent an operation target from being operated against the intention of the operator. In this regard, the technique described in Patent Document 1 is based on the condition that a predetermined hand sign using a hand has been made and that the operator's line of sight is pointing to a specific position. The operation of the operation object based on is permitted. By doing so, it is possible to reduce the manipulation of the manipulation target object due to the movement of the finger against the intention of the operator, and it is possible to realize an information processing apparatus that can prevent an erroneous operation.

JP 2010-277176 A

  Here, even when an operator who is driving the vehicle holds the steering wheel and operates an on-vehicle device (operation object) such as a navigation, the operation object such as a finger is not suitable for the operator's intention. There may be a problem that the state is detected and the in-vehicle device is erroneously operated. For example, when a gesture for sliding the hand along the shape of the steering is associated with a specific operation of the in-vehicle device, based on the sliding motion of the hand when the vehicle rotates the steering wheel to turn the corner A case where the in-vehicle device is operated is considered. Therefore, a technology for preventing an in-vehicle device from being erroneously operated against an operator's intention is also required for an information processing device for a vehicle.

  However, if the information processing apparatus of Patent Document 1 is to be applied to a vehicle, the operator must release his hand from the steering wheel in order to perform a predetermined hand sign, which is problematic in terms of bothering while driving. The present inventors have found that. In addition, it is conceivable that a condition other than a hand sign using the hand is recognized, but it is still necessary to force the operator to perform operations other than operating the in-vehicle device in order to prevent erroneous operation. It is not preferable from the viewpoint of troublesomeness. In addition, "erroneous operation" here refers to operation of the vehicle-mounted device contrary to the operator's intention.

  The present invention has been made in view of the above problems, and it is possible to prevent an in-vehicle device from being erroneously operated against the operator's intention without causing troublesome driving, and an information processing device for a vehicle. An object is to provide an information processing system and a vehicle information processing program.

  An information processing apparatus for a vehicle according to one aspect of the present invention is an information processing apparatus for a vehicle that performs an operation on an operated apparatus that exists inside a vehicle, and the operated apparatus according to a state of an operation article that operates the operated apparatus. The operation content determination means (102) for determining the operation content of the operation, the operation signal output means (103) for outputting a signal related to the operation content determined by the operation content determination means to the operated device, and the steering operation state An output permission / indication instruction means (106, 107) for prohibiting the output of a signal by the operation signal output means when the steering physical quantity, which is a related physical quantity, is equal to or greater than a predetermined output prohibition threshold; Delay time setting means (104) for setting a predetermined delay time from when the operation content is determined until the signal is output by the operation signal output means. Characterized in that it comprises a.

  The effect obtained by the vehicle information processing apparatus which is one of the present invention will be described. Even if the operation content of the operated device is determined according to the state of the operation article by the operation content determination means, if the steering physical quantity is equal to or greater than the predetermined output prohibition threshold, the output permission / indication instruction means determines The output of the signal regarding the operated operation to the operated device is prohibited. Here, it is estimated that the case where the steering physical quantity is equal to or greater than the predetermined output prohibition threshold is that the operator's intention is to operate the steering in accordance with driving. Therefore, when the operator does not intend to operate the operated device but intends to operate the steering, it is possible to prevent the operated device from being operated based on the state of the operation article. it can.

  Further, a predetermined delay time from when the operation content of the operated device is determined by the delay time setting means until the signal is output by the operation signal output means is set. Therefore, contrary to the operator's intention, even if the state of the operation article is detected in accordance with the steering operation and the operation content of the operated device corresponding to the state of the operation article is determined, It can prevent that the signal regarding operation is output with respect to an operating device. Accordingly, output of the signal to the operated device can be prohibited by the output permission instruction means within the delay time, and the operator's intention until the steering physical quantity exceeds the predetermined output prohibition threshold value. In contrast, the operated device can be prevented from being operated.

  Furthermore, according to the present invention, since a hand sign as in the prior art is unnecessary to prevent erroneous operation of the operated device, there is no troublesome operation.

  Therefore, according to the present invention, it is possible to provide an information processing apparatus for a vehicle that can prevent an operated device from being erroneously operated against an operator's intention without causing troublesome driving.

  Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. When only a part of the configuration is described in each embodiment, the configuration of the other embodiment described above can be applied to the other part of the configuration. In addition, not only combinations of configurations explicitly described in the description of each embodiment, but also the configurations of a plurality of embodiments can be partially combined even if they are not explicitly specified unless there is a problem with the combination. .

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the vehicle information processing system 10 according to the present embodiment includes a display unit 13, a camera 14, an angular velocity sensor 15, a steering angle sensor 16, a speed sensor 17, and vehicle information. A processing apparatus 100 is provided.

  The display unit 13 is for presenting various types of information to the driver of the vehicle. The display unit 13 has a display surface that can be operated by a contact operation and a non-contact operation by an operator's fingers, and is installed so that the display surface is disposed at the upper part of the instrument panel. When the display unit 13 can be touched by an operator's finger, for example, an operation target such as an icon that can be operated according to the touch operation is displayed on the display surface. In the present embodiment, the display unit 13 will be described below by taking a so-called instrument panel display as an example, but a head-up display that displays on the front window of the vehicle as a display surface can also be applied. In addition, a multi-information display in which a display surface is arranged on the instrument panel of the vehicle, a display in which a display surface is arranged in the vicinity of various instruments on the instrument panel of the vehicle, and the like can be applied. In the present embodiment, the operator's finger corresponds to the “operation article” in the claims.

  The camera 14 is fixed so that a camera lens is disposed between the steering handle 11 and the indicator 18, and can photograph the movement and shape of the operator's fingers near the steering handle. An infrared irradiation device (not shown) is provided in the vicinity of the camera 14. The movement and shape of the operator's fingers can be photographed even at night by infrared rays emitted from the infrared irradiation device. In addition, the camera 14 transmits the movement and shape of the photographed finger of the operator to the vehicle information processing apparatus 100 as a signal. Hereinafter, the movement of the finger of the operator is referred to as “gesture”. The movement of the finger of the operator is not limited to a one-dimensional movement, and includes a two-dimensional movement and a three-dimensional movement. The camera 14 corresponds to an “operation object detection device” in the claims.

  The angular velocity sensor 15 detects the rotational angular velocity of the steering handle 11 that is rotated by the driver, and outputs a detection result signal to the vehicle information processing apparatus 100. The rotational angular velocity corresponds to “angular velocity” in the claims. Further, the rotational angular velocity of the steering handle 11 may be detected by calculating the time change of the steering angle detected by the steering angle sensor 16.

  The steering angle sensor 16 detects the steering angle of the steering handle 11 that is rotated by the driver, and outputs a detection result signal to the vehicle information processing apparatus 100. The steering angle is an angle at which the steering handle 11 is tilted clockwise and counterclockwise from the neutral state, and corresponds to a “rotation angle” in the claims. The angular velocity sensor 15 and the steering angle sensor 16 correspond to a “steering state detection device” in the claims.

  The speed sensor 17 detects the speed of the vehicle and outputs a detection result signal to the vehicle information processing apparatus 100.

  The vehicle information processing device 100 is a device such as a navigation device or an air conditioner mounted on a vehicle, a mobile phone, or the like according to a contact operation or non-contact operation of the display unit 13 by an operator (for example, a driver). An operation input is performed on the operated device.

  As shown in FIG. 2, the vehicle information processing apparatus 100 includes an operation article state detection unit 101, an operation content determination unit 102, an operation signal output unit 103, a delay time setting unit 104, a delay time setting prohibiting unit 105, and a signal output prohibition. Means 106 and signal output permission means 107 are provided.

  The operation article state detection unit 101 detects the movement, shape, posture, position, and the like of the operator's fingers from the captured image captured by the camera 14. In addition, the operation article state detection unit 101 stores in advance movements of the operator's fingers corresponding to various operations of the operated device. When the movement of the finger of the operator photographed by the camera 14 matches the stored movement or the like, information regarding the matched movement of the finger is transmitted to the operation content determination unit 102. Note that at least one of the movement of the operator's fingers, the change in shape, the change in posture, and the change in position corresponds to the “state change of the operation article” in the claims.

  The operation content determination means 102 determines the operation content of the operated device. Specifically, the operation content of the associated operated device is determined based on the information about the movement of the finger and the like received from the operation article state detection unit 101.

  For example, when the movement of the operator moving the hand along the grip portion 111 of the steering handle 11 is associated with the increase or decrease of the air volume of the air conditioner, or the movement of the operator moving the finger up and down and the volume of the sound device The case where increase / decrease is matched is considered.

  The operation signal output unit 103 outputs an operation command signal for causing the operated device to execute the operation content of the operated device determined by the operation content determining unit 102 to various operated devices. Specifically, when a signal indicating that the operation content is determined is output from the operation content determination unit 102 and a prohibition signal is not output from the signal output prohibition unit 106, the operation is performed on various operated devices. A command signal is output. The operation command signal corresponds to a “signal related to operation content” in the claims.

  The delay time setting unit 104 sets a delay time T from when the operation content of the operated device is determined by the operation content determining unit 102 until the operation signal is output to the operated device by the operation signal output unit 103. To do. The delay time T is set, for example, as an average time of the following times in all operation modes of the steering wheel 11. That is, it is an average of the time from when the movement of the finger of the operator stored in advance is made against the intention of the operator until the steering angle of the steering wheel 11 reaches the output prohibition threshold (for example, 45 °). The delay time T may be stored in advance in a storage medium or may be calculated each time.

  The delay time setting prohibiting unit 105 sets a delay time T for the delay time setting unit 104 while a later-described permission signal is output from the signal output permission unit 107 to the signal output prohibition unit 106. A setting prohibition signal for instructing prohibition is output.

  When the delay time setting unit 104 receives the setting prohibition signal from the delay time setting prohibition unit 105, the delay time setting unit 104 prohibits the setting of the delay time T.

  The signal output prohibition means 106 outputs an output prohibition signal to the operation signal output means 103 in the following cases. That is, the state in which the steering angle of the steering handle 11 detected by the steering angle sensor 16 is equal to or greater than the output prohibition threshold (for example, 45 °) and the rotational angular velocity of the steering handle 11 is within a predetermined numerical range continues for a predetermined time. This is the case. Further, after the steering angle once becomes equal to or greater than the output prohibition threshold (for example, 45 °), the output prohibition signal is continuously output until a state where the steering angle is equal to or less than the output possible threshold (for example, 5 °) continues for a predetermined time. In the present embodiment, the steering angle and the rotational angular velocity of the steering handle 11 correspond to the “steering physical quantity” in the claims.

Here, an example of a calculation method of the steering angle that becomes the output prohibition threshold will be described. When the road curvature η and the vehicle speed V of the road on which the vehicle is traveling are used, the steering angle δFF necessary for turning a curve or the like is expressed by the following equation (1).

A and l are vehicle constants, which are a stability factor and a wheelbase, respectively. A is calculated by the following formula 2.

m is the mass of the vehicle, lf is the distance between the vehicle center of gravity and the front axle, Kf is the tire cornering power per front wheel, lr is the distance between the vehicle center of gravity and the rear axle, and Kr is the tire cornering power per rear wheel. It is. Using these Equations (1) and (2), the steering angle when performing steady circular motion (steady circle turning) with a constant radius is calculated.

  The vehicle speed V is a value detected by the speed sensor 17. The road curvature η may be stored in advance in the vehicle information processing apparatus 100 or may be calculated each time. The steering angle serving as the output prohibition threshold value may be stored in advance, or may be calculated using Formula 1 and Formula 2 each time.

  The steering angle that is the output prohibition threshold increases as the road curvature η and the vehicle speed V increase. The output prohibition threshold value may be stored in advance in a storage medium or may be calculated each time.

  The output prohibition signal is a signal that prohibits the output of an operation command signal that instructs the operated device to perform various operations. When the operation signal output unit 103 receives the output prohibition signal from the signal output prohibition unit 106, the operation signal output unit 103 does not output an operation command signal to the operated device. That is, while the output prohibition signal is being output to the operation signal output means 103, it is impossible to operate the operated device due to the movement of the finger of the operator.

  The signal output permission unit 107 outputs a signal instructing the signal output prohibition unit 106 to stop outputting the output prohibition signal to the operation signal output unit 103 in the following cases. That is, it is a case where the rotational angular velocity of the steering wheel 11 detected by the angular velocity sensor 15 is equal to or less than a predetermined value, or a state where the steering angle is equal to or less than an output possible threshold (for example, 5 °) for a predetermined time. Therefore, during that time, the operation signal output means 103 can output an operation command signal to the operated device. That is, the operated device can be operated by the movement of the operator's fingers. The signal output prohibiting means 106 and the signal output permitting means 107 correspond to “output permission / inhibition instructing means” in the claims.

  Next, a processing flow in the vehicle information processing apparatus 100 will be described with reference to FIG. This process is realized by the vehicle information processing system 10 having a computer executing a program prepared in advance and functioning as various means shown in FIG. The various means are the operation article state detection means 101, the operation content determination means 102, the operation signal output means 103, the delay time setting means 104, the delay time setting prohibition means 105, the signal output prohibition means 106, and the signal output permission means 107. . Further, this program can be stored and handled in a storage medium, and corresponds to a “vehicle information processing program” in the claims.

  First, in S <b> 1, it is determined from the captured image captured by the camera 14 whether or not the movement of the operator's finger matches the movement stored in advance. When it is determined that they do not match (when it is determined No), S1 is repeated again. On the other hand, when it is determined that they match, the operation article state detection unit 101 transmits information regarding the matching finger movement and the like to the operation content determination unit 102, and proceeds to S2.

  In S <b> 2, the operation content determination unit 102 determines the operation content of the operated device associated with the matched finger movement or the like. Then, the operation content determination unit 102 transmits a signal indicating that the operation content has been determined to the operation signal output unit 103, and the process proceeds to S3.

  In S3, it is determined whether or not an operation command signal can be output to the operated device. Specifically, it is determined whether an output prohibition signal is output from the signal output prohibition unit 106 to the operation signal output unit 103. When it is determined that the output prohibition signal is output, that is, when it is determined that the operation command signal cannot be output (when it is determined No), the processing flow of FIG. 3 ends. On the other hand, when it is determined that the output prohibition signal is not output, that is, when it is determined that the operation command signal can be output (when determined Yes), the process proceeds to S4.

  In S4, the delay time setting means 104 determines whether or not the delay time T is set. If it is determined that the delay time T is not set, that is, if the delay time setting is prohibited by the delay time setting prohibiting means 105 (if determined as No), the process proceeds to S6 and the operation signal output means In step 103, an operation command signal is output to the operated device. On the other hand, when it is determined that the delay time T is set, that is, when the setting prohibition signal is output from the delay time setting prohibiting means 105 to the delay time setting means 104 (when it is determined Yes). , Go to S5.

  In S5, it is determined whether or not the delay time T has elapsed since the operation content of the operated device was determined in S2. When it is determined that the delay time T has not elapsed (when it is determined No), the process is repeated from S3. Therefore, if the output prohibition signal is output from the signal output prohibition means 106 to the operation signal output means 103 before the delay time T elapses, it is determined in S3 that the operation command signal cannot be output. . That is, it is determined No. Therefore, the processing flow in FIG. 3 is terminated.

  On the other hand, when it is determined in S5 that the delay time T has elapsed (when determined as Yes), the process proceeds to S6, and an operation command signal is output from the operation signal output means 103 to the operated device. Is done. The operated device is operated based on the operation command signal.

  Next, an example of a series of processing contents of the vehicle information processing apparatus will be described based on an example of an operation mode of the steering handle 11 (see FIGS. 3 to 9). In the present embodiment, the steering wheel 11 in a neutral state as shown in FIG. 4 (the state where the vehicle is traveling on a straight road) is defined as a steering angle of 0 °, and the operator first moves the steering wheel 11 in the direction of the arrow in FIG. Assume a case of rotating operation.

  As shown in FIG. 5, when the steering angle θ becomes an angle θ1 equal to or larger than an output prohibition threshold (for example, 45 °), an output prohibition signal is output from the signal output prohibition means 106 to the operation signal output means 103, and the operated device The output of operation command signals to is prohibited. Thereafter, when the steering handle 11 is further rotated in the direction of the arrow in FIG. 5, the output of the output prohibition signal is continued because the steering angle θ is equal to or greater than the output prohibition threshold (for example, 45 °).

  Next, as shown in FIG. 6, when a predetermined time elapses while the steering angle θ is at an angle θ2 equal to or greater than the output prohibition threshold (for example, 45 °), the signal output permission means 107 outputs permission to the signal output inhibition means A signal is output. The situation in which the steering angle θ is at a predetermined angle and the predetermined time has elapsed, that is, the rotational angular velocity of the steering handle 11 is zero. Further, even if the rotational angular velocity is not completely zero, an output is made when the rotational angular velocity is within a predetermined numerical range centered on zero so that an output permission signal is output in the case of slight movement of the steering wheel 11. A permission signal may be output.

  Then, when the steering handle 11 starts to rotate in the opposite direction from the state shown in FIG. 6, the output prohibition signal is output again from the signal output prohibition means 106 to the operation signal output means 103. Next, the steering handle 11 is rotated in the same direction as it is, and as shown in FIG. 7, the steering angle θ from the neutral state becomes an angle θ3 smaller than an output prohibition threshold (for example, 45 °). explain. Even in this case, when θ3 is larger than a predetermined output possible threshold (for example, 5 °), the output of the output prohibition signal by the signal output prohibition means 106 is continued.

  Next, when the steering handle 11 is further rotated in the rotational direction from the state of FIG. 7, and a predetermined time has passed while the steering angle θ is equal to or less than the output possible threshold (for example, 5 °) as shown in FIG. Will be described. In this case, an output permission signal is output from the signal output permission means 107 to the signal output inhibition means 106.

  Next, the steering handle 11 is rotated from the state of FIG. 7 in the same direction as it is, and the output permission signal is continued until the steering angle θ becomes equal to or larger than the output prohibition threshold (for example, 45 °). Then, as shown in FIG. 9, when the steering angle θ becomes an angle θ4 equal to or larger than the output prohibition threshold (for example, 45 °), the signal output prohibition means 106 outputs an output prohibition signal to the operation signal output means 103. Become.

  Next, effects obtained in the present embodiment will be described.

  (1) Even if the operation content of the operated device is determined by the operation content determination means 102 according to the movement of the operator's finger, the steering angle of the steering wheel 11 is set to a predetermined output prohibition threshold (for example, 45). °) or more. In this case, the signal output prohibiting means 106 prohibits the output of the operation command signal to the operated device. Here, the case where the steering angle is equal to or greater than a predetermined output prohibition threshold value (for example, 45 °) is presumed that the operator's intention is to operate the steering handle 11 during driving. Therefore, when the operator does not intend to operate the operated device but intends to operate the steering handle 11, the operated device is prevented from being operated based on the movement of the fingers. be able to.

  Further, a predetermined delay time T from when the operation content of the operated device is determined by the delay time setting means 104 until the operation command signal is output by the operation signal output means 103 is set. Therefore, contrary to the operator's intention, even if the movement of the fingers is detected in accordance with the operation of the steering handle 11, and the operation content of the operated device corresponding to the movement is determined, An operation command signal can be prevented from being output to the operating device. Therefore, the output of the operation command signal to the operated device can be prohibited by the signal output prohibiting means 106 within the delay time T. And it can prevent that a to-be-operated apparatus is operated contrary to an operator's intention until a steering angle becomes more than a predetermined output prohibition threshold value (for example, 45 degrees).

  Furthermore, according to the present embodiment, a hand sign as in the prior art is not required to prevent an erroneous operation of the operated device, so that it does not bother driving. Therefore, according to the present embodiment, it is possible to provide the vehicle information processing apparatus 100 that can prevent the operated device from being erroneously operated against the intention of the operator without causing troublesome driving.

  (2) In particular, when gestures due to fine movements of the operator's fingers or the like are associated with various operations of the operated device, the steering handle 11 is compared with gestures due to rough movements by the operator's hands. Even a slight operation is easily detected against the operator's intention. Therefore, the effect of preventing the erroneous operation by setting the delay time T is greater in the case of the gesture based on the movement of the operator's finger or the like than the gesture based on the movement of the operator's hand.

  (3) The signal output prohibiting unit 106 operates the operation signal until the steering angle becomes equal to or greater than the output prohibition threshold (for example, 45 °) and becomes equal to or less than a predetermined output enable threshold (for example, 5 °) smaller than the output prohibition threshold. The prohibition of the output of the operation command signal by the output means 103 is continued. Here, the steering handle 11 is relatively inclined from the neutral state until the steering angle of the steering handle 11 once becomes equal to or greater than the output prohibition threshold and becomes equal to or less than the output possible threshold. That is, it is estimated that the vehicle is turning and the operator is operating the steering handle 11 for driving the vehicle. For this reason, it is presumed that the movement of a finger or the like detected during the period from when the steering angle becomes equal to or greater than the output prohibition threshold to equal to or less than the output possible threshold is not based on the intention of operating the operated device. Therefore, by continuously prohibiting the output of the operation command signal by the operation signal output means 103, it is possible to prevent the operated device from being operated against the intention of the operator without bothering the operation. it can.

  (4) The signal output permission means 107 operates the operation signal when the steering angle of the steering wheel 11 becomes equal to or greater than the output prohibition threshold after the steering angle becomes equal to or greater than the output prohibition threshold, The output of the operation command signal by the output means 103 is permitted. For example, in the case of traveling as follows, even if the steering wheel 11 is rotated until the steering angle becomes equal to or greater than the output prohibition threshold and then falls below the output possible threshold, a relatively short time is required. In the meantime, the steering handle 11 is operated in the opposite direction. In other words, this is a case where the vehicle is traveling on a traveling path in which a right curve of a predetermined distance is followed by a left curve of a predetermined distance. In this case, once the steering angle of the steering wheel 11 becomes equal to or less than the output possible threshold, the operator needs to continue to operate the steering wheel 11 for driving. In such a situation, it is important not to bother driving more, but the output of the operation command signal is permitted by the signal output permission unit 107 immediately after the steering angle becomes equal to or less than the output possible threshold. And it is not preferable from the viewpoint of reducing the troublesomeness of driving.

  Here, when the state in which the steering angle of the steering wheel 11 is equal to or less than the output possible threshold value continues for a predetermined time, it is estimated that the vehicle is traveling on a relatively straight traveling path. Therefore, when the state where the steering angle of the steering wheel 11 is equal to or less than the output possible threshold value continues for a predetermined time, the following effects are exhibited. That is, by allowing the output of the operation command signal to the operated device by the signal output permission means 107, it is possible to prevent the operated device from being operated against the operator's intention without causing troublesome operation. can do.

  (5) The signal output permission unit 107 outputs an operation command signal from the operation signal output unit 103 when the state where the steering angle is equal to or greater than the output prohibition threshold and the rotation angular velocity is equal to or less than the predetermined value continues for a predetermined time. To give permission. When the steering angle is equal to or greater than the output prohibition threshold and the rotational angular velocity is equal to or less than the predetermined value, the state where the vehicle is turning on the same R curve or the like continues for the predetermined time. There is a case. In this case, a monotonous driving state in which the operator does not need to greatly change the operation of the steering handle 11 continues for a while. Under such circumstances, the operation content determined based on the movement of the fingers and the like is presumed to be based on the operator's intention. Therefore, by permitting the output of the operation command signal by the signal output permission means 107 under such circumstances, the operation of the operated device becomes possible, and the operation of the operated device is not hindered more than necessary. The operated device can be operated according to the intention of the person.

  (6) When the output of the operation command signal by the operation signal output means 103 is permitted by the signal output permission means 107, the delay time setting prohibiting means 105 prohibits the setting of the delay time T by the delay time setting means 104. To do. Even when the output of the operation command signal by the operation signal output means 103 is permitted, that is, when the operation of the operated device becomes possible by the operator, the delay time T is still set by the delay time setting means 104. May be. In this case, the operator is forced to operate the operated device while feeling annoying. Even if the operator places his / her finger in a predetermined state to operate the operated device, and the operation content determining means 102 determines the operation content of the corresponding operated device, there is a delay time until the operated device is operated. This is because a time lag occurs. However, according to the present embodiment, the operator can operate the operated device without feeling bothered.

  (7) The camera 14 is fixed so that a camera lens is disposed between the steering handle 11 and the indicating instrument 18. Therefore, even when a gesture is made by moving a finger on the counter-operator side of the steering handle 11 while the operator is holding the steering handle 11, it is possible to reliably capture an image with the camera 14. Therefore, it is possible to detect the movement of the finger of the operator with high accuracy.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In addition, description is simplified or abbreviate | omitted about the part which overlaps with 1st Embodiment.

  In the present embodiment, movements of the operator sliding the hand along the annular steering handle 11 are stored in advance in association with various operations of the operated device. Specifically, the operation content determination unit 102 is associated when the operation article state detection unit 101 detects that the displacement amount when the operator slides the hand is larger than a predetermined determination physical quantity threshold. The operation content (for example, increase / decrease in air conditioning temperature) is determined. Specific examples of the determination physical quantity threshold include a threshold based on a moving distance, a rotation angle, and the like.

  Further, if the displacement amount of the operator's hand when the steering handle 11 is rotated until reaching the output prohibition threshold described in the first embodiment is defined as the prohibition physical quantity threshold, the determination physical quantity threshold is greater than the prohibition physical quantity threshold. Is also set as a large value.

  That is, the displacement amount of the operator's hand may reach the determination physical quantity threshold value, and the steering angle of the steering handle 11 may be equal to or greater than the output prohibition threshold value. In this case, although the operation content of the operated device associated with the movement of the operator's hand is determined, since the output prohibition signal is output by the signal output prohibition unit 106, the operation signal output unit 103 No operation command signal is output to the operated device.

  On the other hand, when the displacement amount of the operator's hand is greater than or equal to the prohibited physical quantity threshold and less than the determined physical quantity threshold and the steering angle of the steering wheel 11 is greater than or equal to the output prohibited threshold, the operation signal output means 103 similarly receives An operation command signal is not output to the operating device.

  Further, when the displacement amount of the operator's hand is equal to or greater than the prohibition physical amount threshold and equal to or less than the determination physical amount threshold and the steering angle of the steering handle 11 is less than the output prohibition threshold, it matches the movement of the operator's finger stored in advance. Never do. Therefore, a signal indicating that the operation content has been determined is not output from the operation content determination unit 102 to the operation signal output unit 103. Therefore, the operation command signal is not output from the operation signal output means 103 to the operated device.

  Next, effects obtained by the present embodiment will be described.

  In the present embodiment, the determination physical quantity threshold is larger than the prohibited physical quantity threshold. Therefore, when the hand movement or the like is changed in accordance with the operation of the steering handle 11 without the intention of the operator to operate the operated device, the displacement amount of the operator's hand is determined by the operated device. The forbidden physical quantity threshold is reached prior to reaching the determination physical quantity threshold for determining the operation content. Therefore, it is possible to prevent the operated device from being erroneously operated against the operator's intention.

  In addition, the same effects as those of the first embodiment are obtained.

(Other embodiments)
Although a plurality of embodiments of the present invention have been described above, the present invention is not construed as being limited to these embodiments, and various embodiments and combinations can be made without departing from the scope of the present invention. Can be applied.

  A grip sensor 12 that detects whether or not the steering handle 11 is gripped may be further provided. The grip sensor 12 is provided in the grip portion 111 of the steering handle 11, and a pressure sensor, an electrostatic sensor, an optical sensor, a temperature sensor, or the like can be applied. In this case, the vehicle information processing apparatus 100 may include a grip determination unit 108 that determines how the steering handle 11 is gripped based on the detection result of the grip sensor 12. Further, whether or not the operation command signal is output to the operated device may be determined according to the position where the operator's hand is holding the grip portion 111, the grip strength (pressure, etc.), and the like. Good.

  For example, there is a case where it is determined that the operator is operating the steering handle 11 with an index indicating that the operator is holding the steering handle 11 in a predetermined state. The predetermined state is a state in which the steering handle 11 is gripped with both hands, for example. In this case, it is presumed that the determination of the operation content of the operated device based on the movement of the operator's fingers detected during that time is contrary to the operator's intention. Moreover, since the operator is operating the steering handle 11, it is necessary to avoid troublesome driving.

  Therefore, for example, when the grip sensor 12 detects that the operator is not gripping the steering handle 11 with both hands, the signal output prohibiting unit 106 outputs an output prohibiting signal to the operation signal outputting unit 103. Thus, when the operator does not hold the steering handle 11 with both hands, the operation of the operated device can be prohibited, and the operated device is contrary to the operator's intention without causing troublesome driving. Can be prevented from being operated. The grip sensor 12 corresponds to a “steer grip detection device” in the claims.

  In the above embodiment, the operator's fingers are used to operate the operated device. However, the operated device may be operated by operating an object such as a penlight in the air.

  When the vehicle speed detected by the speed sensor 17 exceeds a predetermined value, an output prohibition signal is output from the signal output prohibition means 106 to the operation signal output means 103 from the viewpoint of reducing troublesome driving. You may make it do.

  In the flowchart shown in FIG. 3, after the determination process in step S <b> 1 and the determination process in step S <b> 2, a determination process is performed in step S <b> 3 as to whether an operation command signal can be output. On the other hand, the determination process of step S1 and the determination process of step S2 may be executed after the determination process of step S3. According to this, it is possible to avoid executing the processing of steps S1 and S2 until output is impossible, and to reduce the calculation load.
