JP 2011-116145 A

  According to the patent document, it is possible to prevent theft of the vehicle to some extent. However, when an intruder enters the vehicle with little impact due to picking or the like, the technology described in the above-mentioned patent document cannot prevent the vehicle from being stolen. In addition, for example, when the user forgets the lock and leaves the key in the vehicle, the technique described in the above-mentioned patent document cannot prevent the vehicle from being stolen. Further, when the impact sensor reacts due to an accident or the like and the engine is stopped, the seat may be moved by the crime prevention control and the passenger may be caught between the seats. Thus, the vehicular security system leaves a lot of room for improvement, and the utility of the vehicular security system can be enhanced by making various improvements. The present invention has been made in view of such a situation, and an object thereof is to provide a highly practical vehicle security system.

In order to solve the above problems, a vehicle security system according to claim 1 of the present application is a vehicle security system for preventing vehicle theft, and the vehicle security system includes at least a vehicle seat. A moving mechanism for moving a part, a sensor for detecting specific information for specifying characteristics of a passenger on the vehicle, and (a) a value serving as an index of the specific information detected by the sensor, A determination unit that determines whether or not a preset threshold value is exceeded; and (b) the movement when the determination unit determines that a value serving as an index of the specific information exceeds the threshold value. A control device having a seat moving unit that controls the operation of a drive source of the mechanism and moves the vehicle seat to a non-operation position different from the position of the vehicle seat during vehicle operation; The specific information includes information relating to the load of the seated person on the vehicle seat, information relating to the gripping force of the door when the door is opened and closed by the seated person on the vehicle seat, and information on the seated person on the vehicle seat. height, a predetermined action of the seated person, characterized in that at least two or more information among the information on at least one of the contours of the sitting person.

  Further, in the vehicle security system according to claim 2, in the vehicle security system according to claim 1, the non-operation position is an end of a moving range of the vehicle seat by the moving mechanism, or the The position is beyond the movement range.

In the vehicle security system according to claim 1, a sensor that detects specific information for specifying the characteristics of a passenger on the vehicle is provided in the vehicle, and an index of the specific information detected by the sensor is provided. It becomes the value is, whether more than a threshold set in advance is determined. When the value serving as the index of the specific information exceeds the threshold value, the vehicle seat moves to a non-operation position that is different from the position of the vehicle seat during vehicle operation. That is, the occupant of the features, specifically, for example, by the body rating or the like of the passenger, the passenger is equal to or a suspicious intruder, passenger is determined to be a suspicious intruder The vehicle seat moves to the non-operating position. This makes it possible to determine whether or not the occupant is a suspicious intruder regardless of impact or the like, and to prevent vehicle theft due to picking, forgetting to lock, or the like. In addition, as long as the passenger is an authorized user, the vehicle seat does not move to the non-operating position, so that an unexpected movement of the seat can be prevented when an accident occurs. Thus, according to the vehicle security system of the first aspect, a highly practical vehicle security system is realized.

  In the vehicular security system according to claim 2, when the occupant is a suspicious intruder, the vehicular seat exceeds the end of the moving range of the vehicular seat by the moving mechanism or the moving range.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

<Configuration of vehicle security system>
FIG. 1 shows a vehicle security system 10 according to an embodiment of the present invention. The vehicle security system 10 is a system for preventing the vehicle from being stolen. The vehicle seat (see FIG. 2) 20 and a plurality of mechanisms 22, 24, 26 for adjusting the seating posture of the vehicle seat 20. , 28, pressure sensors 30, 32, a camera 34, an operation switch 36, and a control device 38.

  The vehicle seat 20 is a seat disposed in the driver's seat. As shown in FIG. 2, the seat cushion 50 that supports the driver's buttocks, the seat back 52 that supports the driver's back, and the seat back. The headrest 54 is provided at the upper end of the head 52 and supports the driver's head, and the side shield 56 covers the side surface of the seat cushion 50. The vehicle seat 20 is a seat capable of adjusting various seating postures electrically, that is, a so-called power seat, and various seating postures are adjusted by the operation of a plurality of mechanisms 22, 24, 26, and 28. . The operation switch 36 is a switch for controlling the operation of a plurality of mechanisms, and is disposed on the side surface of the side shield 56.

  Further, the plurality of mechanisms 22, 24, 26, and 28 are a slide mechanism 22, a reclining mechanism 24, a lifter mechanism 26, and a front tilt mechanism 28, as shown in FIG.

  The slide mechanism 22 has a lower rail (see FIG. 2) 62 fixed to the vehicle floor, an upper rail (see FIG. 2) 64 slidably provided on the lower rail 62, and the lower rail 62 and the upper rail 64 relative to each other. The vehicle seat 20 can be slid in the front-rear direction by driving the electromagnetic motor 60.

  The reclining mechanism 24 includes a reclining gear mechanism (not shown) that can change the inclination angle of the seat back 52 with respect to the seat cushion 50 and an electromagnetic motor 66 that drives the gear mechanism. The inclination angle can be adjusted.

  The lifter mechanism 26 includes a lifter gear mechanism (not shown) that can change the distance between the seat cushion 50 and the vehicle floor, and an electromagnetic motor 68 that drives the lifter gear mechanism. It is possible to adjust the height of the vehicle seat 20.

  The front tilt mechanism 28 includes a gear mechanism (not shown) that can change the tilt amount of the front portion of the seat cushion 50 and an electromagnetic motor 70 that drives the gear mechanism. The amount of tilt of the front portion of the seat cushion 50 can be adjusted.

  The pressure sensor 30 is disposed in the door pocket of the front door on the driver's seat side. For this reason, when a driver's seat, that is, a seated person in the vehicle seat 20 grips the door pocket and opens and closes the front door, the force for gripping the door pocket (hereinafter referred to as “grip force”) And the gripping position of the door pocket is detected by the pressure sensor 30.

  The pressure sensor 32 is disposed on the seating surface of the seat cushion 50 of the vehicle seat 20. For this reason, the seating pressure and seating position of the seated person on the vehicle seat 20 are detected by the pressure sensor 32.

  The camera 34 is disposed in a console disposed in the center of the ceiling, that is, a so-called overhead console. The camera 34 sits on the vehicle seat 20, an image when the passenger gets into the vehicle and sits on the vehicle seat 20. Take images of the passengers who are on board. Since the resolution of the camera 34 is low, it is not possible to clearly photograph the passenger's face and the like, but the contour of the passenger can be recognized from the video of the camera 34. Therefore, by analyzing the video of the camera 34, it is possible to detect the height of the passenger and the predetermined behavior of the passenger.

  The control device 38 includes a controller 76 mainly composed of a computer having a CPU, a ROM, a RAM and the like, and a plurality of drive circuits 78 corresponding to the electromagnetic motors 60, 66, 68 and 70. Electromagnetic motors 60, 66, 68 and 70 corresponding to the drive circuit 78 are connected to the controller 76 via the drive circuit 78. An operation switch 36 is connected to the controller 76. Thus, the controller 76 can control the operation of the slide mechanism 22 and the like in accordance with the input from the operation switch 36. In addition, the pressure sensors 30 and 32 are connected to the controller 76, and the controller 76 acquires the gripping force, the gripping position of the door pocket, the seating pressure of the seated person on the vehicle seat 20, and the seating position. Further, the camera 34 is connected to the controller 76. Thereby, the controller 76 analyzes the video of the camera 34 and acquires information about the height of the passenger and the predetermined behavior of the passenger.

<Security control by vehicle security system>
In the vehicle security system 10, crime prevention control is performed to prevent theft of the vehicle with the above-described configuration. Specifically, every time the user uses the vehicle, the controller 76 uses the pressure sensors 30 and 32 and the camera 34 to grasp the gripping force and the gripping position of the door pocket, the seating pressure of the seated person on the vehicle seat 20 and the seating. Information on the position, the height of the passenger, and the predetermined behavior of the passenger is acquired. When the vehicle user is, for example, one person, the acquired various information generally converges to a specific value, position, and the like.

  Specifically, for example, the user usually opens and closes the door by the same method. For this reason, for example, a user who closes the door by hooking three fingers on the door pocket always closes the door by this method, so the gripping position of the door pocket acquired by the controller 76 corresponds to three fingers. It converges to the position to be. Further, the gripping force of the door pocket acquired by the controller 76 also converges to a high gripping force if the user closes the door with a strong force by the user's heel, and low gripping if the user closes the door with a weak force. Converge to force.

  For example, the user normally sits at the same position of the seat cushion 50 of the vehicle seat 20. For this reason, the seating position on the vehicle seat 20 acquired by the controller 76 converges to a specific position. Further, since the weight of the user does not usually change greatly, the seating pressure on the vehicle seat 20 acquired by the controller 76 also converges to a specific value.

  Further, the predetermined behavior of the passenger when the user gets into the vehicle, for example, the movement of the limbs, the angle between the upper body and the lower body, and the like is generally the same due to the user's heel. For this reason, the predetermined behavior of the passenger acquired by the controller 76 converges to a specific behavior pattern. Further, since the height of the user does not change greatly, the height of the passenger acquired by the controller 76 also converges to a specific value.

  As described above, the various types of information acquired by the controller 76 generally converge to specific values, positions, etc., and the specific values, positions, etc. are stored in the controller 76 as user set values. Each time the passenger gets into the vehicle, the various information acquired by the controller 76 is compared with the user set value. Specifically, for example, when the gripping force of the door pocket is stored as the user setting value A, the threshold value is set to (A−α) or more and (A + α) or less in consideration of the error. Is done. Then, it is determined whether or not the gripping force of the door pocket acquired when the passenger gets into the vehicle is within the threshold value. In this manner, not only the gripping force but also other information such as the gripping position and the seating position are set based on the user setting value, and whether or not the various information acquired by the controller 76 is within the threshold value. Is determined.

  In this determination result, when it is determined that all of a plurality of pieces of information such as the gripping force and the sitting position acquired by the controller 76 are within the threshold value, the person currently on the vehicle is always in the vehicle It is judged that the person is using and is not subject to crime prevention. On the other hand, if it is determined that any one of the plurality of pieces of information acquired by the controller 76 is not within the threshold, the person currently on the vehicle is a person who is always using the vehicle. Instead, the vehicle seat 20 is judged to be a suspicious intruder into the vehicle, and the vehicle seat 20 is moved by the slide mechanism 22, the reclining mechanism 24, and the like to prevent the vehicle from being stolen.

  Specifically, based on the height of the passenger acquired by the controller 76, it is determined whether or not the height of the person currently on the vehicle is 170 cm or less. When it is determined that the height of the person boarding the vehicle exceeds 170 cm, as shown in FIG. 3, the vehicle is placed at the foremost position in the slide range of the vehicle seat 20 by the slide mechanism 22. The seat 20 slides, and the seat back 52 is tilted to a position that is tilted forward in the tilt range of the seat back 52 by the reclining mechanism 24. Further, the seat cushion 50 rises to the uppermost position in the range of movement of the seat cushion 50 by the lifter mechanism 26, and the front of the seat cushion 50 in the inclination range of the seat cushion 50 by the front tilt mechanism 28 is the uppermost position. The seat cushion 50 is inclined at a position inclined in the direction. That is, when the seated person in the vehicle seat 20 is assumed to be a large person, the vehicle seat 20 is moved extremely forward. By moving the vehicle seat 20 to such a position (hereinafter sometimes referred to as a “front-side antitheft position”), a seated person on the vehicle seat 20 can control the steering 80 and the vehicle seat 20. The steering wheel 80 cannot be operated, the ankle is fixed, and the pedal 82 cannot be stepped on. Thereby, a suspicious intruder into the vehicle cannot operate the vehicle and can prevent the vehicle from being stolen.

  On the other hand, when it is determined that the height of the person boarding the vehicle is 170 cm or less, as shown in FIG. 4, at the position of the end of the sliding range of the vehicle seat 20 by the slide mechanism 22, The vehicle seat 20 slides, and the seat back 52 is tilted to a position that is tilted backward most in the tilt range of the seat back 52 by the reclining mechanism 24. Further, the seat cushion 50 rises to the uppermost position in the range of movement of the seat cushion 50 by the lifter mechanism 26, and the front of the seat cushion 50 in the inclination range of the seat cushion 50 by the front tilt mechanism 28 is the uppermost position. The seat cushion 50 is inclined at a position inclined in the direction. That is, when the seated person on the vehicle seat 20 is assumed to be a small person, the vehicle seat 20 is moved extremely rearward. By moving the vehicle seat 20 to such a position (hereinafter sometimes referred to as a “rear anti-theft position”), a seated person on the vehicle seat 20 can grip the steering wheel 80. Therefore, the pedal 82 cannot be depressed. Thereby, a suspicious intruder into the vehicle cannot operate the vehicle and can prevent the vehicle from being stolen.

  Note that if it is determined that the vehicle occupant is a suspicious intruder, the input signal from the operation switch 36 is ignored. Accordingly, the intruder cannot operate the vehicle seat 20 and cannot return the vehicle seat 20 to a position where the vehicle can be operated.

  As described above, in the vehicle security system 10, information such as the user's door opening / closing, sitting habit, and the user's physique is digitized, and the vehicle occupant is based on the digitized information. It is determined whether or not the user is a legitimate user. When it is determined that the occupant is not an authorized user, the vehicle seat 20 moves to a front anti-theft position or a rear anti-theft position that is extremely shifted from the position during vehicle operation. To do. Thereby, it is possible to appropriately prevent the vehicle from being stolen.

  As described above, the information used to determine whether the vehicle occupant is a legitimate user is the user's door opening / closing, sitting habit, user's physique, etc. It is information for specifying For this reason, even if this information is leaked, the user cannot be identified based on this information. In other words, clear user images, fingerprints, irises, and the like have a high risk of personal information leakage, but information that identifies the user's characteristics has low risk of personal information leakage and is safe.

  Further, in the vehicle security system 10, it is possible to set the mode for temporarily preventing the crime prevention control (hereinafter sometimes referred to as “maintenance mode”). Specifically, when the user performs a predetermined operation, the security control is canceled and the maintenance mode is set. In this mode, the information acquired by the controller 76 is not compared with the threshold value, and security control is not executed. Accordingly, for example, in a maintenance factory, a hotel, or the like, a person different from the user can temporarily operate the vehicle. The operation for setting the maintenance mode is preferably an operation that only a user can know, such as operating two predetermined buttons at the same time. In the vehicle security system 10, the operation for canceling the maintenance mode, that is, the operation for returning from the maintenance mode to the crime prevention control is the same as the operation for setting the maintenance mode.

<Control program>
The above-described crime prevention control is performed by executing the control program shown in FIGS. The control program is stored in the controller 76 of the control device 38 and is executed by the controller 76.

  In the control program, in step 100 (hereinafter simply referred to as “S100”. The same applies to other steps), the controller 76 determines whether or not the front door has been opened. When the front door is not opened (NO in S100), the process of S100 is repeated. On the other hand, when the front door is opened (YES in S100), the pressure is detected by the pressure sensor 30 disposed in the door pocket in S102. As a result, the controller 76 acquires the gripping force and the gripping position of the door pocket. Next, in S <b> 104, the controller 76 analyzes the image data acquired by the camera 34. Thereby, the controller 76 acquires information on the height of the passenger and the predetermined behavior. Subsequently, in S106, the pressure is detected by the pressure sensor 32 provided in the seat cushion 50 of the vehicle seat 20. Accordingly, the controller 76 acquires the seating pressure and the seating position on the vehicle seat 20.

  Next, in S108, the controller 76 determines whether or not an operation for canceling the security control, that is, an operation for setting the maintenance mode has been performed. When the release operation is not performed (NO in S108), in S110, the controller 76 determines whether or not it is in the maintenance mode. When the maintenance mode is not in effect (NO in S110), the controller 76 determines whether or not the gripping force and gripping position of the door pocket acquired in S102 are within the threshold value.

  When the gripping force and the gripping position of the door pocket are within the threshold (YES in S112), in S114, the controller 76 determines whether or not the analysis result acquired in S104 is within the threshold. When the analysis result is within the threshold (YES in S114), in S116, the controller 76 determines whether or not the seating pressure acquired in S106 is within the threshold. If the seating pressure is within the threshold (YES in S116), in S118, the controller 76 determines whether or not the seating position acquired in S106 is within the threshold. When the seating position is within the threshold (YES in S118), in S120, the controller 76 causes the gripping force, the gripping position, and the analysis result acquired in S102 to S106 (information on the height of the occupant and the predetermined action). , The seating pressure and the seating position are stored as user set values. Then, the process of the control program ends.

  Further, when the gripping force and the gripping position of the door pocket are not within the threshold value at S112 (NO at S112), when the analysis result is not within the threshold value at S114 (NO at S114), when the seating pressure is not within the threshold value at S116 (S116). If the seating position is not within the threshold value in S118 (NO in S118), the process proceeds to S122. In S122, the controller 76 determines whether the height of the occupant is 170 cm or less based on the analysis result acquired in S104. When the height of the occupant exceeds 170 cm (NO in S122), in S124, the controller 76 controls the operation of the slide mechanism 22, the reclining mechanism 24, etc., and moves the vehicle seat 20 to the front antitheft position. Move. Then, the process proceeds to S128.

  On the other hand, when the height of the occupant is 170 cm or less (YES in S122), in S126, the controller 76 controls the operation of the slide mechanism 22, the reclining mechanism 24, etc., and moves the vehicle seat 20 to the rear side antitheft position. Move to. Then, the process proceeds to S128. In S128, the controller 76 determines whether or not the operation switch 36 has been operated. When the operation switch 36 is operated (YES in S128), the controller 76 ignores the signal of the operation switch 36 in S130. Then, the process of the control program ends. On the other hand, if the operation switch 36 has not been operated (NO in S128), the process of S130 is skipped and the process of the control program ends.

  Further, when the release operation is performed in S108 (YES in S108), in S132, the controller 76 determines whether or not the operation is the first time. If the release operation is the first time (YES in S132), the controller 76 releases the security control and starts the maintenance mode. Then, the process of the control program ends.

  On the other hand, when the release operation is the second time (NO in S132), the controller 76 ends the maintenance mode. And it progresses to S112 and the process after S112 is performed.

  If the maintenance mode is in S110 (YES in S110), the process returns to S134, and the processes after S134 are performed.

<Functional configuration of controller>
The controller 76 that executes the control program includes a determination unit 86 and a sheet moving unit 88, as shown in FIG. The determination unit 86 is a functional unit that executes the processes of S112 to S118, that is, a functional unit for determining whether information for specifying the characteristics of the passenger such as the gripping force and the seating position is within the threshold value. It is. In addition, the seat moving unit 88 controls the operation of the functional units that execute the processes of S124 and S126, that is, the slide mechanism 22, the reclining mechanism 24, and the like, and moves the vehicle seat 20 to the front antitheft position or the rear side. It is a functional part for moving to a theft prevention position.

  Incidentally, in the said Example, the vehicle security system 10 is an example of a vehicle security system. The vehicle seat 20 is an example of a vehicle seat. The slide mechanism 22, the reclining mechanism 24, the lifter mechanism 26, and the front tilt mechanism 28 are examples of a moving mechanism. The pressure sensors 30 and 32 are examples of sensors. The camera 34 is an example of a sensor. The control device 38 is an example of a control device. The electromagnetic motors 60, 60, 68, and 70 are examples of drive sources. The determination unit 86 is an example of a determination unit. The sheet moving unit 88 is an example of a sheet moving unit. Information on gripping force, gripping position, seating position, seating pressure, passenger height, and predetermined behavior of the passenger is an example of specific information. The front anti-theft position and the rear anti-theft position are examples of non-operating positions.

  In addition, this invention is not limited to the said Example, It can implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, the slide mechanism 22, the reclining mechanism 24, the lifter mechanism 26, and the front tilt mechanism 28 are employed as the mechanism for moving the vehicle seat 20, but other types are employed. It is possible to employ this mechanism. Specifically, it is possible to adopt a mechanism for changing the lumbar support mechanism, the length of the seat cushion 50 in the front-rear direction, the folding angle of the seat back 52, the folding angle of the side support, the inclination angle of the headrest 54, and the like. Is possible. For example, when the lumbar support mechanism is adopted and the occupant is determined to be a suspicious intruder, the lumbar support mechanism may be actuated to tighten the seated person on the vehicle seat 20 as shown in FIG. Is possible. In particular, by operating the lumbar support mechanism at the front anti-theft position shown in FIG. 3, it is possible to prevent the seated person from being sandwiched between the steering wheel 80 and the vehicle seat 20 and detached from the vehicle seat 20. is there.

  Further, in the above embodiment, the security control is executed by using the mechanism already provided in the power seat, but the mechanism dedicated to the security control is provided, and the mechanism dedicated to the security control is used. It is possible to execute crime prevention control. Specifically, for example, as shown in FIG. 9, a mechanism for raising the seat cushion 50 is provided, and when the occupant is determined to be a suspicious intruder, the mechanism is operated to steal the vehicle. Can be prevented. With such a mechanism, it is possible to appropriately prevent the vehicle from being stolen, for example, even in a type of vehicle in which the seat back 52 such as a truck cannot be largely tilted rearward. In addition, for example, as shown in FIG. 10, a mechanism for tilting the entire vehicle seat 20 backward is provided, and when the occupant is determined to be a suspicious intruder, by operating the mechanism, It is also possible to prevent theft. Thus, by providing a mechanism dedicated to crime prevention control, the crime prevention control can be executed even in a vehicle seat that is not a power seat.

  Furthermore, for example, as shown in FIG. 11, a slide mechanism 90 that slides the vehicle seat 20 is provided separately from the slide mechanism 22, and the slide mechanism 90 moves the slide seat 22. By moving beyond the range, theft of the vehicle can be prevented. Specifically, the slide mechanism 90 includes a slide body 92 and a base 94. The slide body 92 is fixed to the lower rail 62, and the base 94 is fixed to the floor 96 of the vehicle. The slide body 92 and the base 94 are slidable. Note that the backward sliding amount of the slide body 92 is larger than the backward sliding amount by the slide mechanism 22.

  Further, the slide body 92 is urged toward the rear by a coil spring (not shown). However, in a normal state, the slide body 92 and the base 94 are locked, and the vehicle seat 20 is fixed at a position where the vehicle can be operated. In the slide mechanism 90 having such a structure, when the occupant is determined to be a suspicious intruder, the slide body 92 and the base 94 are unlocked, and the slide body 92 is moved backward by the elastic force of the coil spring. Slide toward. At this time, due to the slide of the slide body 92, the vehicle seat 20 moves rearward from the position where it is slid to the rearmost end by the slide mechanism 22. The slide body 92 and the base 94 are locked in a state where the slide body 92 is slid rearward. Thus, by operating the slide mechanism 90, the vehicle seat 20 can be moved considerably rearward, and the vehicle can be suitably prevented from being stolen.

  In the above embodiment, it is determined whether the vehicle seat 20 is to be moved to the front anti-theft position or the rear anti-theft position based on the height of the passenger. It is possible to determine based on The weight of the passenger can be estimated by the pressure sensor 32 disposed on the seat cushion 50 of the vehicle seat 20.

  Further, in the above embodiment, as information for specifying the characteristics of the passenger, the gripping force, the gripping position, etc. of the door pocket are adopted, but various information such as the gripping force, the gripping position of the steering wheel 80, etc. It can be adopted as information for specifying the characteristics of the passenger. In addition, various sensors such as an infrared sensor, a capacitance sensor, and a temperature sensor can be employed as sensors for detecting information.

  Moreover, in the said Example, although the vehicle security system 10 is used for anti-theft of a motor vehicle, it is possible to apply the technique of this invention for anti-theft of a motorcycle etc.
