DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of an in-vehicle valuables theft prevention system according to the present invention will be described in detail below with reference to the drawings. Note that in the drawings used in the following description, each component is shown at a different scale so that it can be recognized on the drawing. The present invention is not limited to the number, shape, size ratio, and relative positional relationship of the components shown in these drawings.

[0010] The vehicle valuables theft prevention system 1 shown in Figure 1 includes a control unit (hereinafter referred to as ECU) 2, an information display 3, a user authentication device 4, a camera 5, a driver monitoring system (hereinafter referred to as DMS) 6, a warning device 7, a seat unit 10, and a valuables box 20.

[0011] The ECU 2 is electrically connected to the information display 3, user authentication device 4, DMS 6, warning device 7, seat unit 10, and valuables box 20. The ECU 2 is composed of a microcomputer equipped with a CPU, ROM, RAM, non-volatile storage, etc. The ROM stores control programs and fixed data for implementing operations set for each system.

[0012] The information display 3 comes in various forms, and this description is applicable to any of them. The information display 3 is configured so that various settings displayed on the information display 3 can be input by touch panel operation. The information display 3 includes, for example, a multi-information display provided in the instrument panel that displays information on fuel economy and various driving-related information in addition to instruments that display a speedometer and engine RPM.

[0013] Furthermore, the information display 3 constitutes a user setting device that not only displays basic screens such as car navigation, date, time, and fuel economy, but also includes a multi-function display located above the center of the dashboard that allows customization of various items such as DMS6 settings, and a center information display located in the audio space located below the center of the dashboard.

[0014] The user authentication device 4 is a biometric authentication device such as a fingerprint authentication reader, a voice recognition device, etc. The driver 100, who is an occupant, can register settings for when he / she gets in the car, such as the driving position and the angle of the side mirrors, by being authenticated by the user authentication device 4.

[0015] The DMS 6 is a biometric authentication device separate from the user authentication device 4, and is a facial authentication device for the driver 100. The DMS 6 is connected to a camera 5, which is an imaging unit. The camera 5 is placed, for example, approximately in the center of the dashboard. The camera 5 may be installed anywhere in the cabin as long as it is positioned so as to be able to capture an image of the driver 100 seated in the seat unit 10.

[0016] The warning device 7 issues a warning by sound from a speaker, by warning lights around the meters on the instrument panel, by displaying a warning on the information display 3, on the monitor of the navigation system, or the like.

[0017] The seat unit 10 has a seat cushion 11, a seat back 12, a headrest 13, and a seat leg portion 14. The seat cushion 11, the seat back 12, the headrest 13, and the seat leg portion 14 form a seat 30, which is a driver's seat in this example.

[0018] The seat cushion 11 constitutes a seating portion on which the occupant (driver) 100 sits. The seat back 12 constitutes a backrest portion on which the occupant 100 leans. The headrest 13 is configured to support the head of the occupant 100 and is height-adjustable.

[0019] The seat leg 14 is a frame provided below the seat cushion 11. The seat leg 14 is disposed on a floor panel, which is the floor of the vehicle body. The seat leg 14 forms a support frame that supports the seat cushion 11 from below.

[0020] The seat 30, which is composed of a seat cushion 11, a seat back 12, and a headrest 13, can be freely adjusted in the longitudinal direction of the vehicle to suit the physique and driving position of the occupant 100. A slide mechanism 15 is provided that is slidably connected to the seat legs 14 and fixed to the floor panel.

[0021] The slide mechanism 15 has a lower rail and a slider fixed to a floor panel. The lower rail extends in the front-rear direction of the vehicle. The slide mechanism 15 slides the seat 30 back and forth.

[0022] A slide motor 16, which serves as a drive source, is provided on the seat leg portion 14 below the seat cushion 11. The slide motor 16 is connected to the ECU 2. The slide motor 16 is controlled and driven by the ECU 2.

[0023] The seat 30 slides back and forth along the lower rails of the slide mechanism 15 by rotation of the slide motor 16. That is, the seat 30 is a so-called electric power seat that slides by operating a power seat switch (not shown) to adjust the slide.

[0024] In addition to the slide mechanism, the seat 30 is configured to have a well-known front vertical mechanism, a lifter mechanism, a reclining mechanism, a lumbar support adjustment mechanism, and the like.

[0025] A power seat switch and a seat memory switch (not shown) are provided on the side of the seat cushion 11, the upper door trim, etc. By operating these switches, the driver 100 can register a desired driving position in the seat memory switch in advance, and the position of the seat 30 can be electrically changed.

[0026] A seat position detection sensor 17 is provided on the seat leg 14. The seat position detection sensor 17 is connected to the ECU 2. The seat position detection sensor 17 detects the position of the seat 30 in the front-rear direction and outputs a detection signal to the ECU 2.

[0027] The maximum sliding position of the seat 30 in the vehicle valuables theft prevention system 1 will now be described in detail.

[0028] The vehicle valuables theft prevention system 1 defines movement to a first maximum forward movement position P1 as shown in FIG. 2 and a second maximum forward movement position P2 as shown in FIG. 3 when the seat 30 is slid forward to its maximum position.

[0029] The first maximum forward movement position P1 of the seat 30 is a position where the valuables box 20 is hidden under the seat cushion 11 of the seat 30. That is, at the first maximum forward movement position P1, the seat 30 is in a position where the seat cushion 11 and the valuables box 20 overlap. Here, the seat 30 can only move within the range of a first sliding distance FL1.

[0030] The second maximum forward movement position P2 of the seat 30 is a position where the seat cushion 11 of the seat 30 moves further forward than the valuables box 20, exposing the valuables box 20. That is, at the second maximum forward movement position P2, the seat 30 is in a position where the seat cushion 11 and the valuables box 20 do not overlap. Here, the seat 30 can move within a range of a second sliding distance FL2 that is longer than the first sliding distance FL1.

[0031] The vehicle valuables theft prevention system 1 has a first mode that specifies the maximum forward sliding position of the seat 30 so that it can only be moved to a first maximum forward movement position P1. In this first mode, even if the seat 30 is slid forward to the maximum, the valuables box 20 is hidden under the seat cushion 11 of the seat 30.

[0032] Therefore, the first mode is a normal seat movement mode, and is an anti-theft storage box opening / closing disabled mode in which the valuables box 20 cannot be accessed.

[0033] The vehicle valuables theft prevention system 1 also has a second mode that specifies the maximum forward sliding position of the seat 30 so that it can be moved to a second maximum forward movement position P2. In this second mode, by sliding the seat 30 forward to the maximum extent, the valuables box 20 is exposed behind the seat cushion 11.

[0034] Therefore, the second mode is a valuables storage and retrieval mode, which is a storage box openable and closable mode in which the valuables box 20 can be accessed.

[0035] The ECU 2 receives the position of the seat 30 detected by the seat position detection sensor 17. The ECU 2 then controls the slide motor 16 to slide the seat 30 forward to the first maximum forward movement position P1 or the second maximum forward movement position P2 depending on the first mode or the second mode.

[0036] In addition, the vehicle valuables theft prevention system 1 may be configured to specify movement to a first maximum rearward movement position P3 as shown in Figure 4 and a second maximum rearward movement position P4 as shown in Figure 5 when the seat 30 is slid rearward to its maximum position.

[0037] The first maximum rearward movement position P3 of the seat 30 is a position where the valuables box 20 is hidden under the seat cushion 11 of the seat 30. That is, at the first maximum rearward movement position P3, the seat 30 is in a position where the seat cushion 11 and the valuables box 20 overlap. Here, the seat 30 can only move within the range of a third sliding distance RL1.

[0038] The second maximum rearward movement position P4 of the seat 30 is a position where the seat cushion 11 of the seat 30 moves further rearward than the valuables box 20, exposing the valuables box 20. That is, at the second maximum rearward movement position P4, the seat 30 is in a position where the seat cushion 11 and the valuables box 20 do not overlap. Here, the seat 30 can move within a range of a fourth sliding distance RL2 that is longer than the third sliding distance RL1.

[0039] The vehicle valuables theft prevention system 1 has a third mode that specifies the maximum rearward sliding position of the seat 30 so that it can only be moved to a first maximum rearward movement position P3. In this third mode, even if the seat 30 is slid rearward to the maximum extent, the valuables box 20 is hidden under the seat cushion 11 of the seat 30. Therefore, the third mode is a normal seat movement mode, and is an anti-theft storage box opening / closing disabled mode in which the valuables box 20 cannot be accessed.

[0040] The vehicle valuables theft prevention system 1 also has a fourth mode that specifies the maximum rearward sliding position of the seat 30 so that it can be moved up to a second maximum rearward movement position P4. In this fourth mode, by sliding the seat 30 rearward to the maximum extent, the valuables box 20 is exposed forward of the seat cushion 11.

[0041] Therefore, the fourth mode is a valuables storage and retrieval mode, which is a storage box openable and closable mode in which the valuables box 20 can be accessed.

[0042] The ECU 2 receives the position of the seat 30 detected by the seat position detection sensor 17. The ECU 2 then controls the slide motor 16 to slide the seat 30 rearward to the first maximum rearward movement position P3 or the second maximum rearward movement position P4 depending on the third mode or the fourth mode.

[0043] In addition, the vehicle valuables theft prevention system 1 may be configured to specify the maximum movement of the seat 30 at a first maximum rearward movement position P3 and a second maximum rearward movement position P4 in addition to the first maximum forward movement position P1 and the second maximum forward movement position P2.

[0044] Furthermore, the ECU 2 may detect the first maximum forward movement position P1, the second maximum forward movement position P2, the first maximum rearward movement position P3, and the second maximum rearward movement position P4 of the seat 30 based on the number of rotations of the slide motor 16.

[0045] Next, the configuration of the valuables box 20 will be described in detail below.

[0046] Valuables box 20 is fixed to the floor panel of the vehicle body. As shown in Fig. 6, valuables box 20 has a box-shaped storage section 22 that is open at the top, and a lid section 23 that is a lid body that closes the opening of storage section 22.

[0047] A card reader 25 is mounted inside the storage section 22. This card reader 25 is an on-board device (called an ETC on-board device in Japan) into which a valuable item, a card for an automatic toll payment system for toll roads (called an ETC card in Japan) is inserted and which reads card information.

[0048] The card reader 25 is connected to the ECU 2 and wirelessly communicates with an antenna installed at the toll booth of the toll road via a vehicle antenna (not shown) connected to the ECU 2 to transmit card information required for toll payment.

[0049] An electronic lock 21 is provided on the storage section 22 and the lid section 23. The electronic lock 21 is composed of, for example, an electronic lock actuator 21a and a striker 21b. The electronic lock actuator 21a is provided on the storage section 22 side here.

[0050] The electronic lock actuator 21a is electrically connected to the ECU 2. The locking and unlocking of the electronic lock actuator 21a is controlled by the ECU 2.

[0051] The cover 23 is provided with a striker 21b that is locked by the electronic lock actuator 21a.

[0052] The ECU 2 unlocks the electronic lock 21 only when the seat 30 is moved to the second maximum forward movement position P2 in the second mode or the second maximum rearward movement position P4 in the fourth mode. The ECU 2 also locks the electronic lock 21 when the seat 30 is moved from the second maximum forward movement position P2 or the second maximum rearward movement position P4. The valuables box 20 may be configured as a cylinder lock that locks and unlocks the lid 23 to the storage section 22 with a key.

[0053] As shown in Fig. 6, the lid 23 of the valuables box 20 opens and closes relative to the storage section 22 by means of a pivot point of a hinge mechanism 24. The lid 23 may alternatively be a sliding type relative to the storage section 22, as shown in Fig. 7.

[0054] The vehicle valuables theft prevention system 1 configured as described above has a first mode and a third mode, which are normal seat movement modes in which the valuables box 20 cannot be opened or closed according to the sliding position of the seat 30. The vehicle valuables theft prevention system 1 also has a second mode or a fourth mode, which are valuables storage and retrieval modes in which the valuables box 20 can be opened or closed.

[0055] When the vehicle valuables theft prevention system 1 is not in the valuables storage / retrieval mode, the normal seat movement mode is set as a default setting. Also, the vehicle valuables theft prevention system 1 is set to the valuables storage / retrieval mode by the driver 100 operating the information display 3.

[0056] Here, the user setting, which is the initial setting when the driver 100 executes the vehicle valuables theft prevention system 1, and the access to the valuables box 20 will be described below with reference to the flowchart of FIG.

[0057] 8, the driver 100 turns on the ignition (S1), and then opens a setting screen from the home screen of the information display 3 (S2).

[0058] At this time, the driver 100 opens the setting screen of the information display 8 by operating the touch panel of the information display 3. Then, the driver 100 selects execution of the valuables storage and retrieval mode (S3).

[0059] When the valuables storage / retrieval mode is selected, the vehicle valuables theft prevention system 1 sets the second mode, in which the seat 30 is slid to the second maximum forward movement position P2, as the basic setting.

[0060] The driver 100 may be able to specify either the second mode or the fourth mode when selecting execution of the valuables storage / retrieval mode. That is, the driver 100 may be able to selectively specify either the second mode in which the seat 30 is slid to the second maximum forward movement position P2 or the fourth mode in which the seat 30 is slid to the second maximum rearward movement position P4.

[0061] At this time, the vehicle valuables theft prevention system 1 causes the ECU 2 to control the driving of the slide motor 16, thereby sliding the seat 30 to the second maximum forward movement position P2 or the second maximum rearward movement position P4.

[0062] When the seat 30 reaches the second maximum forward movement position P2 or the second maximum rearward movement position P4 based on the detection signal of the seat position detection sensor 17, the ECU 2 stops driving the slide motor 16. Then, the ECU 2 unlocks the electronic lock 21.

[0063] The driver 100 opens the lid 23 of the valuables box 20 and stores valuables in the storage section 22 (S4). Next, the driver 100 operates the touch panel of the information display 3 to select user settings (S5) and performs user registration for the valuables storage mode (S6).

[0064] User registration is performed by the driver 100 using the user authentication device 4 for fingerprint authentication, a voice recognition device, or the like, or by face authentication using the DMS 6 or inputting a personal identification number by operating the touch panel of the information display 3. Note that user registration of the driver 100 may be performed selectively using a plurality of combinations of fingerprint authentication, a voice recognition device, face authentication, or personal identification number registration.

[0065] After completing the user registration, the driver 100 selects the home screen by operating the touch panel of the information display 3 (S7). In this way, the vehicle valuables theft prevention system 1 executes the valuables storage / retrieval mode. The information display 3 may be configured to automatically return to the home screen upon completion of user registration for the valuables storage mode.

[0066] Furthermore, when the vehicle valuables theft prevention system 1 returns to the home screen, the seat 30 may be returned to its original position when the ignition was turned on by the driving control of the slide motor 16 by the ECU 2. The driver 100 may also move the seat 30 to a desired position by himself or herself using the power seat switch and the seat memory switch.

[0067] Furthermore, the user who can register the valuables storage and retrieval mode is not limited to the driver 100, but may be another occupant. Also, it is preferable that only the last user who registered can cancel the user registration for the valuables storage mode.

[0068] Next, an example of control executed by the ECU 2 of the vehicle valuables theft prevention system 1 will be described below with reference to the flowchart shown in FIG.

[0069] The ECU 2 of the vehicle valuables theft prevention system 1 determines whether or not the valuables storage / retrieval mode is being executed (S11).

[0070] If the valuables storage / retrieval mode is not being executed (step S11: NO), the ECU 2 executes the normal seat movement mode (S20), which restricts the seat 30 to sliding forward and backward only between the first maximum forward movement position P1 and the first maximum rearward movement position P3.

[0071] As a result, the vehicle valuables theft prevention system 1 can prevent the valuables box 20 from being exposed even when the seat 30 is moved forward and backward to the maximum extent. Note that this normal seat movement mode is executed as an anti-theft storage box opening / closing disabled mode in which the valuables box 20 cannot be accessed.

[0072] If the valuables storage and retrieval mode is being executed (step S11: YES), the ECU 2 determines whether or not an opening operation of the valuables box 20 has been detected (S12). If an opening operation of the valuables box 20 has not been detected (step S12: NO), the ECU 2 repeatedly executes the determination routine of this step S12.

[0073] The valuables box 20 is opened by the driver 100, for example, by operating the touch panel of the information display 3. At this time, an open signal for the valuables box 20 is input to the ECU 2 from the information display 3. The valuables box 20 may also be opened by operating a smart key.

[0074] When the ECU 2 detects an operation to open the valuables box 20 (step S12: YES), the ECU 2 performs user authentication (S13). Then, the ECU 2 determines whether or not the user is a registered user of the valuables storage and retrieval mode (S14).

[0075] At this time, the ECU 2 performs user authentication based on fingerprint authentication by the user authentication device 4, face authentication by the voice recognition device or DMS 6, or input information of a personal identification number by the driver 100 operating the touch panel of the information display 3.

[0076] If the user is not a registered user in the valuables storage and retrieval mode (step S14: NO), the ECU 2 issues a warning (S21). The ECU 2 issues a warning at a predetermined time by sound from the speaker of the warning device 7, a warning light around the meter on the instrument panel, a display on the information display 3, a monitor of the navigation system, etc.

[0077] Then, the ECU 2 executes the normal seat movement mode (S20), whereby the vehicle valuables theft prevention system 1 prevents the valuables box 20 from being exposed and from being accessed even when the seat 30 is moved forward or backward to the maximum extent.

[0078] If the user is a registered user in the valuables storage and retrieval mode (step S14: YES), the ECU 2 automatically slides the seat 30 to the second maximum forward movement position P2 or the second maximum rearward movement position P4 (S15).

[0079] The ECU 2 controls the driving of the slide motor 16 so as to slide the seat 30 forward or backward to the maximum extent possible, up to a second maximum forward movement position P2 or a second maximum rearward movement position P4. The ECU 2 moves the seat 30 to the second maximum forward movement position P2 or the second maximum rearward movement position P4 that is designated in advance by the driver 100 at the time of initial setting.

[0080] Then, ECU 2 unlocks electronic lock 21 (S16). In this way, vehicle valuables theft prevention system 1 moves seat 30 to positions (P2, P4) where valuables box 20 is exposed, allowing driver 100 to open lid 23 of valuables box 20 and access storage section 22. This allows driver 100 to store (put) or take out valuables, etc. in storage section 22.

[0081] The ECU 2 determines whether or not an end operation has been input (S17). If an end operation has not been input (step S17: NO), the ECU 2 repeatedly executes the determination routine of step S17.

[0082] The termination operation is performed by the driver 100 by closing the lid 23 of the valuables box 20 and operating the touch panel of the information display 3, for example. Note that the ECU 2 may recognize the termination operation when the driver 100 operates the power seat switch and the seat memory switch.

[0083] If the end operation is input (step S17: YES), the ECU 2 locks the electronic lock 21 (S18). In this way, the cover 23 of the valuables box 20 is locked to the storage section 22.

[0084] The ECU 2 restores the position of the seat 30 (S19) and ends this control. Note that the ECU 2 controls the driving of the slide motor 16 so as to slide the seat 30 to the original position before the opening operation of the valuables box 20 in step S12, for example.

[0085] As described above, the vehicle valuables theft prevention system 1 of this embodiment is configured such that the valuables box 20 is disposed under the seat cushion 11 of the seat 30, and has a normal seat movement mode in which the valuables box 20 cannot be opened or closed depending on the sliding position of the seat 30, and a valuables storage and retrieval mode in which it can be opened and closed.

[0086] The vehicle valuables theft prevention system 1 is configured to control the position of the seat 30 so that it can be slid back and forth only within a range where the valuables box 20 is hidden under the seat cushion 11 of the seat 30 in a normal seat movement mode.

[0087] Furthermore, the vehicle valuables theft prevention system 1 is configured to control the seat cushion 11 of the seat 30 to move forward or backward relative to the valuables box 20 in the valuables storage / retrieval mode, upon authentication by a registered user, in this case the driver 100, so that the seat 30 can be slid back and forth to a position where the valuables box 20 is exposed.

[0088] Therefore, even in the event of a vehicle break-in, the vehicle valuables theft prevention system 1 cannot access the valuables box 20, which is a valuables storage section inside the vehicle, unless the user is authenticated as a registered user in the valuables storage and retrieval mode. In other words, the vehicle valuables theft prevention system 1 can prevent valuables in the valuables box 20 from being stolen because the seat 30 can only be slid back and forth within a range where the valuables box 20 is hidden under the seat cushion 11 of the seat 30.

[0089] The control unit (ECU) 2 has a processor including a central processing unit (CPU) and storage devices such as ROM and RAM. All or part of the configuration of the processor's circuits may be implemented by software. For example, the CPU may read and execute various programs corresponding to the respective functions stored in the ROM.

[0090] Furthermore, all or part of the functions of the processor may be configured using logic circuits or analog circuits, and the processing of various programs may be realized using electronic circuits such as FPGAs.

[0091] The invention described in the above embodiments is not limited to those embodiments, and various modifications can be made in the implementation stage without departing from the gist of the invention. Furthermore, each of the above embodiments includes inventions at various stages, and various inventions can be extracted by appropriate combinations of the disclosed multiple constituent elements.

[0092] For example, if some constituent elements are deleted from all the constituent elements shown in each form, and the stated problem can still be solved and the stated effect can still be obtained, then the configuration from which these constituent elements have been deleted can be extracted as an invention.
