DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Next, an embodiment of the present invention will be described in detail with reference to the drawings, taking as an example a case where the vehicle door control system of the present invention is applied to a side door for a front seat on the right side of a vehicle (driver's seat in Japan). In the reference drawings, "front and rear" refers to the front and rear direction in the traveling direction of the vehicle, i.e., the front and rear direction of the vehicle body, and "left and right" refers to the left and right direction (vehicle width direction) as seen from the driver's seat.

[0011] As shown in FIG. 1, a vehicle to which a vehicle door control system 1 according to an embodiment of the present invention is applied includes a vehicle body 2 and a door (side door) 3 provided on the vehicle body 2.

[0012] <Door> The door 3 is provided so as to be able to open and close an opening 2a (see FIG. 3) on a side surface in the vehicle width direction (right side surface in this embodiment) of the vehicle body 2. The door 3 is attached so as to be able to swing relative to the vehicle body 2 in a plan view, with a front end portion of the door 3 serving as a rotation axis X1 extending in the vertical direction.

[0013] As shown in FIG. 2, the vehicle door control system 1 includes a lock unit 10, a drive unit 20, an operation unit 30, an angle detection unit 41, an opening / closing detection unit 42, a load detection unit 43, a surrounding detection unit 44, and a control unit 50.

[0014] <Lock section> The lock unit 10 operates a latch mechanism capable of keeping the door 3 in a closed state and a lock mechanism capable of switching the latch mechanism between an unlocked state and a locked state based on the operation of the door handle or key cylinder by a user (passenger) and a control signal from the control unit 50. The lock unit 10 includes a latch operating unit 11 and a lock operating unit 12. <Latch operation part> The latch operating unit 11 operates the latch mechanism of the door 3 in the closed state based on the operation of the door handle by the user, a control signal from the control unit 50, etc., to enable the door 3 to be opened.

[0015] <Lock operation part> The lock operating unit 12 operates the lock mechanism of the door 3 in a closed state based on the user's operation of the key cylinder, a control signal from the control unit 50, etc., to place the door 3 in an unlocked state in which it can be opened, or in a locked state in which it cannot be opened.

[0016] <Drive unit> The drive unit 20 drives the door 3 to open and close (to swing) based on a control signal from the control unit 50 and the like.

[0017] As shown in FIG. 3, the drive unit 20 includes a spindle screw 21 supported on the vehicle body 2 so as to be capable of swinging, a spindle nut 22 provided on the door 3 side and capable of screwing into the spindle screw 21, a motor 23 provided on the door 3 side and connected to the spindle nut 22 via a reduction mechanism, and a brake unit 24.

[0018] The base end of the spindle screw 21 is supported on the front edge of the opening 2a of the vehicle body 2 with a rotation axis X2 extending in the vertical direction. The rotation axis X2 is provided on the inner side of the rotation axis X1 of the door 3 in the vehicle width direction.

[0019] The drive unit 20 changes the screwing position of the spindle nut 22 to the spindle screw 21 by the rotational drive of the motor 23. This makes it possible to change the opening / closing angle of the door 3 relative to the vehicle body 2.

[0020] The brake unit 24 is an electromagnetic brake incorporated in the motor 23 or the speed reducing mechanism, and switches between a state in which relative movement of the spindle nut 22 with respect to the spindle screw 21 in the direction in which the door 3 opens (openable / closable state) and a state in which relative movement is prohibited (hold state) based on a control signal from the control unit 50. The brake unit 24 is not limited to an electromagnetic brake, and may be a physical brake (clutch, etc.).

[0021] The braking force of the brake unit 24 is set so as to be able to support the load when a user leans against the door 3. The drive unit 20 is configured so as to be able to open the door 3 when a load sufficiently larger than the braking force acts on the door 3 in the hold state.

[0022] <Operation section> 2, the operation unit 30 is composed of an intelligent key, a switch provided in the vehicle, etc., and outputs the result of an operation by a user to the control unit 50. The operation unit 30 also includes a release unit 31 for releasing a hold state, which will be described later.

[0023] <Angle detection unit> The angle detection unit 41 is a sensor that detects the opening / closing angle of the door 3 relative to the vehicle body 2 (including parameters correlated with the opening / closing angle) and outputs the detection result to the control unit 50. The angle detection unit 31 is provided in the drive unit 20, and may be a sensor that counts, for example, pulses of the motor 23 of the drive unit 20 as parameters correlated with the opening / closing angle and outputs the count result to the control unit 50. The control unit 50 can calculate the opening / closing angle of the door 3 based on the count result.

[0024] <Open / close detection unit> The open / close detection unit 42 is a sensor that detects whether the door 3 is in a closed state (fully closed state) or an open state, and outputs the detection result to the control unit 50. In this embodiment, the open / close detection unit 42 detects the state of a latch mechanism (not shown) that can fix the door 3 to the vehicle body 2 as the open / close state of the door 3.

[0025] <Load detection section> The load detection unit 43 is a sensor that detects an external load acting on the door 3 and outputs the detection result to the control unit 50. In this embodiment, the load detection unit 43 detects a load in a direction perpendicular to the surface direction of the door 3 (opening direction and closing direction).

[0026] <Periphery detection section> The periphery detection unit 44 is a sensor that detects an object present around the door 3 and outputs the detection result to the control unit 50. The periphery detection unit 44 can be realized by a camera, an infrared camera, an ultrasonic sensor, or the like.

[0027] <Control Unit> The control unit 50 is a so-called ECU (Electronic Control Unit) that is configured by a CPU (Central Processing Unit), a ROM (Read-Only Memory), a RAM (Random Access Memory), an input / output circuit, etc. When the operation result of the operation unit 30 indicates automatic opening / closing, the control unit 50 controls the drive unit 20 to automatically open / close the door 3. When the operation result of the operation unit 30 indicates manual opening / closing, the control unit 50 controls the drive unit 20 based on the detection result of the load detection unit 43 to generate an assist force that assists the user in manually opening / closing the door 3 (assist mode).

[0028] The control unit 50 controls the drive unit (hold unit) 20 to switch the drive unit 20 between an openable / closable state and a hold state. The openable / closable state is a state in which the door 3 can (is allowed to) move automatically or manually in both the open direction and the closed direction. The hold state is a state in which the door 3 can (is allowed to move automatically or manually in the closed direction) and cannot (is prohibited to move automatically or manually in the open direction. The door 3 with the drive unit 20 in the hold state can support the weight of an occupant without moving in the open direction even if a user who wants to get in or out of the vehicle places his or her hand on the inside of the door 3, and therefore can favorably assist the occupant in getting in or out of the vehicle.

[0029] When the door 3 stops in an open state, the control unit 50 sets the drive unit (hold unit) 20 to a hold state. The control unit 50 can recognize that the door 3 is in an open state based on the detection result of the angle detection unit 41. The control unit 50 can also recognize that the door 3 is stopped based on the detection result of the angle detection unit 41 or the control state of the drive unit 20.

[0030] In this embodiment, the control unit 50 sets the drive unit (hold unit) 20 to a hold state when the door 3 stops moving in the opening direction, and sets the drive unit (hold unit) 20 to an openable / closable state when the door 3 stops moving in the closing direction. The control unit 50 can recognize the moving direction of the door 3 based on the detection result of the angle detection unit 41 or the control state of the drive unit 20.

[0031] Furthermore, the control unit 50 permits the hold state when the detection result of the angle detection unit 41 is equal to or greater than a first predetermined angle (e.g., 15 degrees), and prohibits the hold state when the detection result of the angle detection unit 41 is less than the first predetermined angle (e.g., 15 degrees). That is, when the opening / closing angle of the door 3 is equal to or greater than the first predetermined angle, the drive unit (hold unit) 20 can switch between the openable / closable state and the hold state. When the opening / closing angle of the door 3 is less than the first predetermined angle, the drive unit (hold unit) 20 can only take the openable / closable state. Therefore, when the opening / closing angle of the door 3 is less than the first predetermined angle, the drive unit (hold unit) 20 in the hold state switches to the openable / closable state.

[0032] <Example of operation> Next, an operation example of the vehicle door control system 1 according to the embodiment of the present invention, that is, an operation example of switching the drive unit (hold unit) 20 between the openable / closable state and the hold state, will be described in the order of the open direction and the close direction with reference to the flowcharts of Fig. 4 and Fig. 5 (see Figs. 1 to 3 as appropriate). When the operation result of the operation unit 30 indicates an opening operation of the door 3 and / or when the user is manually performing an opening operation of the door 3 (which can be determined based on the detection results of the angle detection unit 41 and the load detection unit 43), the control unit 50 controls the lock unit 10 and the drive unit 20 according to the flowcharts of Fig. 4 or 5. Also, when the operation result of the operation unit 30 indicates a closing operation of the door 3 and / or when the user is manually performing a closing operation of the door 3 (which can be determined based on the detection results of the angle detection unit 41 and the load detection unit 43), the control unit 50 operates according to the flowchart of Fig. 6.

[0033] <Opening direction operation example / First opening operation example> First, an operation example (first opening operation example) of the opening operation of the vehicle door control system 1 will be described with reference to the flowchart of Fig. 4. In an initial state, the door 3 is slightly opened from a closed state by the operation of the lock unit 10 under the control of the control unit 50, and the drive unit (hold unit) 20 is set to an openable / closable state.

[0034] When the operation result of the operating unit 30 indicates an automatic opening operation of the door 3 (automatic in step S1), the control unit 50 controls the drive unit 20 to move the door 3 in the opening direction (step S2A). On the other hand, when the operation result of the operating unit 30 indicates a manual opening operation of the door 3 (manual in step S1), the control unit 50 controls the drive unit 20 to assist the movement of the door 3 in the opening direction (step S2B).

[0035] After execution of step S2A (during the opening drive), if there is an operation of the operating unit 30 (an operation requesting stopping of the door 3) (Yes in step S3), the control unit 50 stops the door 3 by controlling the drive unit 20 (step S7).

[0036] Furthermore, after execution of step S2A (during the opening drive), if the load detection unit 43 detects a load equal to or greater than the first predetermined value (Yes in step S4), the control unit 50 controls the drive unit 20 to stop the door 3 (step S7). The control unit 50 stops the door 3, for example, when the door 3 hits a person, or when the door 3 is pushed in the opening or closing direction by wind, a user, or the like.

[0037] Furthermore, after execution of step S2A (during the opening drive), if the periphery detection unit 44 detects an object on the trajectory of the door 3 (Yes in step S5), the control unit 50 stops the door 3 by controlling the drive unit 20 (step S7). The control unit 50 stops the door 3, for example, when an object (person, obstacle, etc.) is located on the trajectory of the door 3 in the opening direction (including dynamic detection), when a moving body (car, bicycle, etc.) is approaching on the trajectory of the door 3 in the opening direction, etc.

[0038] If the door 3 is not stopped midway after step S2A is executed (during the opening drive) (No in steps S3, S4, and S5), and the detection result of the angle detection unit 41 is less than a second predetermined angle (greater than the first predetermined angle and smaller than the structural maximum open angle of the door 3 (e.g., any angle between about 65 degrees and about 75 degrees); for example, 45 degrees) (No in step S6), this flow returns to step S1.

[0039] If the door 3 is not stopped midway after execution of step S2A (during the opening drive) (No in steps S3, S4, S5), and if the detection result of the angle detection unit 41 is equal to or greater than the second predetermined angle (Yes in step S6), the control unit 50 controls the drive unit 20 to stop the door 3 (step S7). Similarly, if the detection result of the angle detection unit 41 is equal to or greater than the second predetermined angle (Yes in step S6) after execution of step S2B, the control unit 50 controls the drive unit 20 to stop the door 3 (step S7).

[0040] On the other hand, when the user stops the manual operation of opening the door 3 after step S2B is executed, the control unit 50 controls the drive unit 20 to stop assisting the door 3 in the opening direction (step S7).

[0041] After execution of step S7, if the detection result of the angle detection unit 41 is equal to or greater than the first predetermined angle (Yes in step S8), the control unit 50 controls the drive unit (hold unit) 20 to put the drive unit 20 into a hold state and prohibits movement of the door 3 in the opening direction (step S9).

[0042] When getting on, a user places their hands on the door 3 with the drive unit 20 in the hold state from the inside, and can get on with their weight supported by the door 3. Similarly, when getting off, a user places their hands on the door 3 with the drive unit 20 in the hold state from the inside, and can get off with their weight supported by the door 3. Furthermore, if a user unintentionally touches the door 3 when getting on or off, the vehicle door control system 1 can prevent the door 3 from opening.

[0043] On the other hand, after step S7 is executed, if the detection result of the angle detection unit 41 is less than the first predetermined angle (No in step S8), the present flow returns to step S1.

[0044] After step S9 is executed, if the release unit 31 is operated by the user (Yes in step S10), the control unit 50 controls the drive unit (hold unit) 20 to set the drive unit 20 to an openable / closable state (step S11), and the flow returns to step S1. This makes it possible to open the door 3 further automatically or manually.

[0045] If the results are YES in step S6 and YES in step S10, the control unit 50 resets the second predetermined angle (e.g., 45 degrees) to a predetermined additional angle (e.g., 5 degrees). This makes it possible to automatically or manually open the door 3 further even when the door 3 is opened to the second predetermined angle (before the resetting).

[0046] <Example of opening direction / Example of second opening direction> Next, an operation example (second opening operation example) of the opening operation of the vehicle door control system 1 will be described with reference to the flowchart of FIG. 5, focusing on the differences from the first opening operation example.

[0047] 5, after step S11 is executed, the flow proceeds to step S2B. That is, when the control unit 50 releases the hold state of the drive unit (hold unit) 20 after the door 3 is stopped and sets it to an openable / closable state, the control unit 50 prohibits the drive unit (hold unit) 20 from automatically opening (and closing) the door 3, and controls the drive unit (hold unit) 30 to assist the movement of the door 3 in the opening direction (and closing direction).

[0048] <Example of closing direction> Next, an example of the closing operation of the vehicle door control system 1 will be described with reference to the flowchart of Fig. 6. In the initial state, the door 3 is open, and the drive unit (hold unit) 20 is set to the hold state (assuming that step S9 has been executed).

[0049] 6, when the operation result of the operation unit 30 indicates an automatic closing operation of the door 3 (automatic in step S21), the control unit 50 controls the drive unit 20 to set the drive unit (hold unit) 20 in an openable / closable state (step S22A) and moves the door 3 in the closing direction (step S23A). On the other hand, when the operation result of the operation unit 30 indicates a manual closing operation of the door 3 (manual in step S21), the control unit 50 controls the drive unit 20 to set the drive unit (hold unit) 20 in an openable / closable state (step S22B) and assists the movement of the door 3 in the closing direction (step S23B).

[0050] When getting on, the user, while seated in the seat during execution of step S24B, places his / her hand on the door 3 from the inside and closes the door 3. Similarly, when getting off, the user, while executing step S24B, places his / her hand on the door 3 from the outside and closes the door 3.

[0051] After execution of step S23A (while the closing drive is being performed), if there is an operation of the operating unit 30 (an operation requesting the stopping of the door 3) (Yes in step S24), the control unit 50 stops the door 3 by controlling the drive unit 20 (step S28), and the flow returns to step S21.

[0052] Furthermore, after execution of step S23A (during execution of the closing drive), if the load detection unit 43 detects a load equal to or greater than the first predetermined value (Yes in step S25), the control unit 50 controls the drive unit 20 to stop the door 3 (step S28), and the flow returns to step S21. The control unit 50 stops the door 3, for example, when the door 3 hits a person, or when the door 3 is pushed in the opening or closing direction by wind, a user, or the like.

[0053] Furthermore, after execution of step S23A (during execution of the closing drive), if the periphery detection unit 44 detects an object on the trajectory of the door 3 (Yes in step S26), the control unit 50 controls the drive unit 20 to stop the door 3 (step S28), and the flow returns to step S22B. The control unit 50 stops the door 3, for example, when an object (person, obstacle, etc.) is located on the trajectory of the door 3 in the closing direction (including dynamic detection), when a moving body (car, bicycle, etc.) is approaching on the trajectory of the door 3 in the closing direction, etc.

[0054] That is, when the door 3 stops midway during the closing operation, the control unit 50 does not put the drive unit (hold unit) 20 into the hold state, and allows the movement of the door 3 in the opening direction. More specifically, when the door 3, which is in the openable / closable state during the closing operation, stops midway, the control unit 50 maintains the openable / closable state of the drive unit (hold unit) 20. Also, when the door 3, which is in the hold state during the closing operation, stops midway, the control unit 50 switches the drive unit (hold unit) 20 to the openable / closable state (for example, prohibits the hold state).

[0055] If the door 3 is not stopped midway after step S23A is executed (during execution of the closing drive) (No in steps S24, S25, and S26), and if the detection result of the angle detection unit 41 does not indicate the fully closed state (including the almost fully closed state) of the door 3 (No in step S27A), this flow returns to step S21. On the other hand, if the detection result of the angle detection unit 41 indicates the fully closed state (including the almost fully closed state) of the door 3 (Yes in step S27A), this flow ends. For example, when the detection result of the angle detection unit 41 indicates the almost fully closed state of the door 3, the control unit 50 stops the drive unit 20, and then controls the latch operation unit 11 to change the door 3 from the half-latch state (half-open state) to the full-latch state, thereby bringing the door 3 into the fully closed state. In other words, "the door 3 is almost fully closed" means that the angle of the door 3 is an angle at which the door 3 can be switched from the half-open state to the fully closed state by the operation of the latch operation unit 11.

[0056] Similarly, if the user stops the manual closing operation of the door 3 after step S23B is executed and the closing operation of the door 3 stops midway (step S28 after No in step S27B), this flow returns to step S21. On the other hand, if the detection result of the angle detection unit 41 indicates that the door 3 is in a fully closed state (including an almost fully closed state) after step S23B is executed (Yes in step S27B), this flow ends. For example, when the detection result of the angle detection unit 41 indicates that the door 3 is in an almost fully closed state, the control unit 50 stops the drive unit 20 and then controls the latch operation unit 11 to change the door 3 from a half-latched state to a fully-latched state, thereby bringing the door 3 into a fully closed state.

[0057] <Example of how to release the hold state> As shown in Fig. 7, when the load detection unit 43 detects a load in the opening direction that is equal to or greater than a second predetermined value (greater than the first predetermined value) (Yes in step S31), the control unit 50 may be configured to set the drive unit (hold unit) 20 to an openable / closable state (step S32). This allows the door 3 to move in the opening direction due to the load, and protects the drive unit (hold unit) 20. The control unit 50 may be configured to gradually switch the drive unit 20 from the hold state to the openable / closable state.

[0058] A vehicle door control system 1 according to an embodiment of the present invention comprises a door 3 that can be opened and closed by a swing action relative to a vehicle body 2, a hold unit (drive unit 20) that can switch between an open / close state that allows movement of the door 3 in the opening and closing direction and a hold state that prohibits movement of the door 3 in the opening direction and allows movement in the closing direction, and a control unit 50 that controls the hold unit, and when the door 3 is stopped in the open position, the control unit 50 puts the hold unit into the hold state. Therefore, the vehicle door control system 1 can improve the ease of boarding and disembarking for passengers by enabling them to board and disembark using the door 3 in the held state as support while also closing the door 3, thereby contributing to the development of a sustainable transportation system.

[0059] In the vehicle door control system 1, the control unit 50 sets the holding unit to the hold state when the door 3 stops while moving in the opening direction, and does not set the holding unit to the hold state when the door 3 stops while moving in the closing direction. Therefore, the vehicle door control system 1 can improve the ease of getting in and out of the vehicle after the opening operation of the door 3 by enabling both the ingress and egress of the vehicle using the door 3 in the held state as support and the closing operation of the door 3. In addition, the vehicle door control system 1 can improve the operability of the door 3 by allowing the opening operation of the door 3 after the closing operation of the door 3.

[0060] The vehicle door control system 1 includes a release unit 31 that can be operated by a user, and when the release unit 31 is operated, the control unit 50 changes the hold unit from the held state to the openable / closable state. Therefore, the vehicle door control system 1 can open the door 3 further when the opening / closing angle of the door 3 is insufficient for passengers getting in and out of the vehicle.

[0061] In the vehicle door control system 1, the control unit 50 puts the holding unit into the hold state when the door 3, whose holding unit has been put into the openable / closable state by operation of the release unit 31, stops while moving in the opening direction. Therefore, the vehicle door control system 1 can appropriately assist the occupant in getting in and out of the vehicle without increasing the number of operations by the occupant by placing the hold portion of the door 3 in the hold state again after the door 3 has been opened further.

[0062] In the vehicle door control system 1, the control unit 50 prohibits the hold state when the opening / closing angle of the door 3 is equal to or smaller than a predetermined angle (first predetermined angle). Therefore, when the opening / closing angle of the door 3 is small enough not to be suitable for getting on and off, the vehicle door control system 1 can allow the door 3 to be opened and closed while avoiding an unnecessary hold state.

[0063] The vehicle door control system 1 includes a drive unit 20 that drives the door 3 to open and close, and the control unit 50 controls the drive unit 20 as the hold unit. Therefore, the vehicle door control system 1 can simplify the system by sharing the drive unit 20 and the hold unit.

[0064] In the vehicle door control system 1, the control unit 50 releases the hold state of the drive unit 20 when a load in the opening direction of the door 3 that is in the hold state by the drive unit 20 is applied to the door 3 of a predetermined value (second predetermined value) or more. Therefore, the vehicle door control system 1 can prevent the drive unit 20 from being damaged due to a large load.

[0065] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be modified as appropriate within the scope of the present invention. For example, the drive unit 20 as a holding unit may perform at least one of automatic opening and closing and assisting manual opening and closing of the door 3. The hold unit may be provided separately from the drive unit 20, and in this case, the vehicle door control system 1 may be configured not to have the drive unit 20. The control unit 50 may be configured to determine that the door 3 is opened or closed manually when the operation result of the operation unit 30 indicating the automatic opening and closing of the door 3 is not input in steps S1 and S23. The control unit 30 may be configured not to execute assistance by the drive unit 20 during manual opening and / or closing of the door 3 (100% manual power). [Explanation of symbols]
