  The present invention relates to a vehicle control system and a vehicle control method for controlling an in-vehicle device mounted on a vehicle using one or a plurality of portable terminals carried by a user.

  Conventionally, a vehicle control system that controls an in-vehicle device mounted on a vehicle using one or a plurality of portable terminals (including a key fob and a smartphone) carried by a user has been developed.

  In Patent Document 1, a user raises his hand, lowers his hand, or performs a command operation (so-called remote operation) to swing his / her arm up / down / left / right in a state where the smart bracelet is worn on the arm. Control systems for controlling have been proposed.

Chinese Patent Application Publication No. 104008635 ([0005] to [0009], [0033])

  By the way, when using a portable terminal such as a smart bracelet, a slight movement by the user may be captured to cause an unintended remote operation (for example, automatic opening / closing of a door). Therefore, when performing remote operation of the automatic door opening / closing device as an in-vehicle device, it is desirable to narrow the range for receiving remote operation (hereinafter, “permitted range”) in advance in order to improve the anti-theft performance for the vehicle.

  On the other hand, there is a risk that the convenience in an emergency may be impaired by narrowing the above-mentioned permission range. The reason is that when the user observes that there is an object or the like between the doors being opened and closed, he / she must move to a position within the permitted range in order to enable remote operation. is there.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle control system and a vehicle control method that can achieve both the anti-theft property and automatic convenience in automatic door opening and closing.

  A vehicle control system according to a first aspect of the present invention is mounted on a vehicle and connected to a vehicle-side communication unit capable of wireless communication in a communication range around the vehicle, and connected to the vehicle-side communication unit. A vehicle-side control unit that controls the operation of the in-vehicle device, a first portable terminal that is carried by the user and is capable of wireless communication with the vehicle-side communication unit, and carried by the user, the first portable terminal; A second mobile terminal capable of wireless communication between the first mobile terminal and the first mobile terminal to perform operation control of the in-vehicle device in response to a command operation of the user using the second mobile terminal. A command signal serving as a trigger is transmitted to the vehicle-side communication unit, and the vehicle-side control unit operates the vehicle-mounted device when the first portable terminal is within a permission range that is a part of the communication range. While performing control, from the communication range to the permitted range When the first portable terminal is within the excluded range, the operation control of the in-vehicle device is restricted, and the in-vehicle device includes an automatic door opening and closing device capable of automatically opening and closing the door of the vehicle, The side control unit accepts the command operation using the second portable terminal even though the first portable terminal is within the limit range on the condition that the door is being opened and closed. Control is performed to stop the operation of the automatic door opening / closing device or to reversely operate the automatic door opening / closing device.

  Thus, in principle, the operation control of the in-vehicle device is limited when the first mobile terminal is within the limit range, but the second mobile terminal is an exceptional condition that the door is being opened and closed. Since the door automatic opening / closing device is stopped or reversely operated by accepting a command operation using, it is possible to achieve both the anti-theft property and the emergency convenience in the automatic door opening / closing.

  The first mobile terminal or the second mobile terminal may be configured such that when the user moves from a predetermined position within the communication range to the outside of the predetermined position, the vehicle-side communication unit and the first mobile terminal A notification operation for notifying that the wireless communication between the two is disconnected may be performed. As a result, the user who has received the notification can be kept within the limit range in which the command operation can be accepted.

  The vehicle control system further includes a state detection unit that detects a specific state during the opening / closing operation of the door, and the first portable terminal or the second portable terminal is configured to detect the specific state by the state detection unit. When the is detected, a notification operation for prompting the command operation using the second portable terminal may be performed. Thereby, even if it is a situation where a user is difficult to notice a specific state, the door opening / closing operation can be quickly stopped.

  The second portable terminal may be a wearable terminal that can be worn by the user and configured to accept the user's gesture operation as the command operation. Thereby, the time required for the command operation is greatly reduced.

  In addition, the vehicle-side communication unit is capable of wireless communication with an external device using a plurality of communication methods with different communication limit distances, and the communication range is a communication method with a relatively long communication limit distance. The permitted range may be a communicable range based on a communication method in which the communication limit distance is relatively short.

  Further, the permission range is a range in which a reception strength when receiving a radio signal from the vehicle-side communication unit is higher than a threshold value, and the restriction range is a range in which the reception strength is lower than the threshold value. Good.

  A vehicle control method according to a second aspect of the present invention is mounted on a vehicle and connected to the vehicle-side communication unit capable of wireless communication in a communication range around the vehicle, and connected to the vehicle-side communication unit. A vehicle-side control unit that controls the operation of the in-vehicle device, a first portable terminal that is carried by the user and is capable of wireless communication with the vehicle-side communication unit, and carried by the user, the first portable terminal; A second mobile terminal capable of wireless communication between the first mobile terminal and the second mobile terminal in response to a command operation of the user using the second mobile terminal. A transmission step of transmitting a command signal serving as a trigger for executing operation control of the in-vehicle device to the vehicle-side communication unit; and the vehicle-side control unit is within a permission range that is a part of the communication range. The in-vehicle device when there is a first portable terminal A control step for restricting operation control of the in-vehicle device when the first portable terminal is within a restricted range excluding the permitted range from the communication range, And an automatic door opening and closing device capable of automatically opening and closing the door of the vehicle, and the control step includes that the first portable terminal is within the restricted range on the condition that the door is being opened and closed. Regardless, the command operation using the second portable terminal is accepted, and the operation of the automatic door opening / closing device is stopped, or the automatic door opening / closing device is reversely operated.

  According to the vehicle control system and the vehicle control method according to the present invention, it is possible to achieve both the anti-theft property and the emergency convenience in automatic door opening and closing.

[Operation of Vehicle Control System 10]
The vehicle control system 10 according to this embodiment is configured as described above. Subsequently, operations by the vehicle control system 10, specifically, a notification function and a remote operation function will be schematically described.

  Here, a Bluetooth (registered trademark) pairing connection is set between the vehicle 12 and the smartphone 14 and between the smartphone 14 and the wearable terminal 16. That is, in the vehicle control system 10, [1] wireless communication is performed between the vehicle 12 and the smartphone 14, and [2] wireless communication is performed between the smartphone 14 and the wearable terminal 16, while [3] wireless communication is performed between the vehicle 12 and the wearable terminal 16. Note that this is not done.

<1. Overview of notification function>
The integrated control unit 28 acquires the detection value from the vehicle state sensor 24 and detects the state of the in-vehicle device 26 that is the monitoring target. The in-vehicle communication device 20 transmits a wireless signal (hereinafter referred to as a status signal) related to the state of the in-vehicle device 26 to the surroundings of the vehicle 12 through wireless communication (hereinafter referred to as BT communication) that relays the BT antenna 32 according to transmission control by the integrated control unit 28. Send regularly to.

  The status signal includes, for example, information indicating on / off of an ignition switch, unlocking / locking of a door lock unit, opening / closing of a door, or on / off of a power source. In addition to or separately from this, the state signal includes information indicating the consistency between the ideal state after getting off and the current state.

  When the smartphone 14 is located in a predetermined communication area (hereinafter referred to as a BT area), the smartphone 14 receives the state signal transmitted from the vehicle 12 side via the BT antenna 48 of the first terminal side communication unit 40. Thereby, the smartphone 14 can acquire the state of the in-vehicle device 26.

  When the smartphone 14 is located in a range out of the BT range (hereinafter, out of the BT range), the smartphone 14 cannot receive the state signal transmitted from the vehicle 12 side. At this time, the smartphone 14 analyzes the state signal received most recently, and performs control (hereinafter referred to as notification control) to notify the wearable terminal 16 when it is determined that there is “forgotten operation” by the user U.

<2. Overview of remote control function>
When the smartphone 14 is located within the BT range and receives a command operation of the user U using the wearable terminal 16, the smartphone 14 transmits a command signal indicating that the in-vehicle device 26 is remotely operated to the outside.

  The integrated control unit 28 determines whether or not other conditions (for example, the position condition of the user U) are satisfied as necessary using the reception of the command signal via the in-vehicle communication device 20 as a trigger. If the integrated control unit 28 obtains a positive determination result, it controls the operation of the in-vehicle device 26 according to the content of the command signal.

<Assumed issues>
As shown in FIGS. 2 to 4, the user U who is in a substantially circular BT area (hereinafter, within the communication range 80) puts the smartphone 14 in the pocket 83 of the clothing 82 (here, pants). Carrying. Further, the user U is carrying the wristwatch-type wearable terminal 16 with the arm 84 being worn.

  In the example of FIG. 2, the user U is at a position close to the vehicle 12, specifically, a position within the permission range 86 that is a part of the communication range 80. The substantially semicircular permission range 86 is a communicable range of wireless communication (hereinafter referred to as LF communication) that relays the three LF antennas 33 between the key fob 18 and the in-vehicle communication device 20. It is formed in three places, a right side part, a left side part, and a rear part.

  At this time, the wearable terminal 16 displays an operation screen 88 that prompts the user U to perform a remote operation. On the operation screen 88, there are arranged a message 90 written as [slide door operation], an icon 91 schematically showing the closing operation of the door 30, and a button 92 written as [CLOSE]. When the user U performs a remote operation of touching the button 92, the opened door 30 can be automatically closed.

  In the example of FIG. 3, the user U is at a position away from the vehicle 12, specifically, a position within the limit range 94. The restriction range 94 is a range in which LF communication cannot be performed between the key fob 18 and the in-vehicle communication device 20 (in other words, the remaining range excluding the permission range 86 from the communication range 80). At this time, the wearable terminal 16 displays an operation restriction screen 98 indicating that the remote operation by the user U is restricted, instead of the operation screen 88 of FIG.

  In this way, the smartphone 14 is within the communication range 80 and can perform BT communication with the in-vehicle communication device 20, but the range for accepting remote operation is narrowed in advance to prevent the vehicle 12 from being stolen. Can increase the sex.

  On the other hand, as shown in FIG. 4, it is assumed that the user U senses that the object O is likely to jump out of the passenger compartment during the closing operation of the door 30. In this case, the user U needs to move from the restriction range 94 that is the current position to the permission range 86 before performing remote control using the wearable terminal 16. Alternatively, when the user U performs a remote operation using the smartphone 14, there is a possibility that it takes time to take out the smartphone 14 stored in the pocket 83 or the like. Hereinafter, a vehicle control method capable of achieving both the anti-theft property and the emergency convenience in the automatic opening and closing of the door 30 will be proposed.

<Explanation regarding this control method>
A vehicle control method using the vehicle control system 10 of FIG. 1 will be described in detail with reference to the flowchart of FIG. Here, it should be noted that the smartphone 14 and the integrated control unit 28 operate independently.

  In step S <b> 1, the integrated control unit 28 determines whether or not to continue the operation of the vehicle control system 10. When this operation is continued (step S1: YES), the process proceeds to step S2.

  In step S <b> 2, the first terminal-side control unit 46 determines the magnitude relationship between the reception strength (hereinafter referred to as RSSI; Received Signal Strength Indicator) when receiving the state signal from the in-vehicle communication device 20 and the first threshold Th <b> 1. To do. Prior to this determination, the intensity detector 50 detects the RSSI of the most recently received state signal. The first threshold Th1 corresponds to, for example, a lower limit value that ensures communication quality.

  If the user U goes outside the communication range 80, RSSI ≦ Th1 (step S2: NO) is satisfied, and the process proceeds to step S3.

  In step S3, the notification processing unit 52 performs notification processing for the outside of the BT area (in this case, notification control for the wearable terminal 16). First, the notification processing unit 52 analyzes the most recently received state signal and determines whether notification to the user U is necessary. When there is a difference between the ideal state after getting off and the current state with respect to one or a plurality of in-vehicle devices 26, the notification processing unit 52 determines that notification for “forgetting to operate” is necessary. . Here, it is assumed that the user U is informed of forgetting to close the door 30.

  The notification processing unit 52 transmits a control signal for executing a notification operation indicating that the door 30 is open to the outside via the first terminal side communication unit 40. The wearable terminal 16 (second terminal side control unit 66) connected in pairing starts a notification operation by receiving a control signal via the second terminal side communication unit 60.

  The user U recognizes that the user U is already out of the communication range 80 by this notification operation, and approaches the vehicle 12 to return the vehicle-mounted device 26 to a position where it can be remotely operated (within the limit range 94). When the smartphone 14 reaches a position in the communication range 80, the RSSI exceeds the first threshold Th1. That is, since RSSI improves and the relationship of RSSI> Th1 is satisfied (step S2: YES), the process proceeds to step S4.

  In step S <b> 4, the remote operation processing unit 54 determines whether or not the command operation of the user U using the wearable terminal 16 has been received. Here, the “command operation” means a specific operation for commanding the operation of the in-vehicle device 26 that is a target of remote operation. Specifically, a gesture or other operation (such as shaking the wearable terminal 16 strongly) ( For example, it may be a touch operation of the button 92).

  When the wearable terminal 16 (second terminal side control unit 66) detects a specific operation from the second terminal side UI unit 64, the wearable terminal 16 (second terminal side control unit 66) performs remote operation of the in-vehicle device 26 via the second terminal side communication unit 60. The command signal is sent to the outside. Thereby, the integrated control unit 28 receives the command signal from the smartphone 14 via the in-vehicle communication device 20.

  When this command operation has not been received yet (step S4: NO), the process returns to step S1, and steps S1 to S4 are repeated until the operation is received. On the other hand, when the command operation is received (step S4: YES), the process proceeds to step S5.

  In step S5, the remote operation processing unit 54 performs remote operation processing according to the command operation received in step S4. Specifically, the remote operation processing unit 54 transmits a command signal for performing remote operation of the in-vehicle device 26 to the outside via the first terminal side communication unit 40. The paired and connected vehicle 12 (integrated control unit 28) receives a command signal via the in-vehicle communication device 20.

  In step S6, the integrated control unit 28 determines the position of the smartphone 14 using the reception of the command signal in step S5 as a trigger. Specifically, the integrated control unit 28 determines that the smartphone 14 is within the permitted range 86 when LF communication is possible between the key fob 18 and the in-vehicle communication device 20, and when the LF communication is not possible, the smartphone 14 Is within the limit range 94.

  For example, when it determines with the smart phone 14 being in the permission range 86 (step S6: permission range), it progresses to step S7.

  In step S7, the integrated control unit 28 controls the operation of the in-vehicle device 26 in accordance with the contents of the command signal that has already been received. Thereafter, the process returns to step S1, and the flowchart of FIG. 5 is repeatedly executed.

  On the other hand, when it returns to step S6 and it determines with the smart phone 14 being in the restriction | limiting range 94 (step S6: restriction | limiting range), it progresses to step S8.

  In step S <b> 8, the integrated control unit 28 captures the time change of the detection value of the vehicle state sensor 24 and determines whether or not the door 30 is in an opening / closing operation. When it is determined that the door 30 is not in the open / close operation (step S8: NO), the process proceeds to step S9.

  In step S9, the integrated control unit 28 restricts the operation control of the in-vehicle device 26 (that is, does not execute or puts it on hold) even though the command signal has already been received. Thereafter, the process returns to step S1, and the flowchart of FIG. 5 is repeatedly executed.

  However, if it is determined that the door 30 is in an opening / closing operation (step S8: YES), the process advances to step S7 as an exception, and the integrated control unit 28 automatically opens and closes the door according to the contents of the received command signal. Stop control of the device 36 (emergency stop of the door 30) is performed.

  As illustrated in FIG. 6, it is assumed that the user U senses that the object O is likely to jump out of the passenger compartment during the closing operation of the door 30. In this case, the user U can urgently stop the door 30 during the closing operation by performing a gesture operation of waving the arm on which the wearable terminal 16 is worn on the spot within the limit range 94. In particular, by using the wearable terminal 16 that can be worn by the user U and that can accept the user's U gesture operation as a command operation, the time required for the command operation is significantly reduced.

  Note that the integrated control unit 28 may perform control to reversely operate the door automatic opening / closing device 36 in combination with or separately from the stop control of the door 30. Thereby, when the door 30 is in the “closed” operation, the “open” operation is executed, and when the door 30 is in the “open” operation, the “closed” operation is executed.

  In step S <b> 8, when the smartphone 14 or the wearable terminal 16 detects a specific state (for example, a state where the object O is between the doors 30) by the non-contact sensor 38 during the opening / closing operation of the door 30. A notification operation that prompts a command operation using the wearable terminal 16 may be performed. Thereby, even if it is a situation where the user U is hard to notice a specific state, the opening / closing operation | movement of the door 30 can be stopped rapidly.

  In step S3, when the user U moves from the boundary vicinity position 96 (predetermined position) within the communication range 80 to the outside of the boundary vicinity position 96, the wearable terminal 16 or the smartphone 14 You may perform alerting | reporting operation which notifies that the wireless communication between the smart phones 14 will be cut | disconnected. As will be described later, the user U who has received the notification can be kept within the limit range 94 in which the command operation can be accepted.

  Here, the boundary vicinity position 96 in FIG. 6 may be a set of positions that are a predetermined distance from the boundary line (communication limit position) of the communication range 80, or RSSI = Th1 + Δ (Δ is a positive minute value) It may be a set of positions satisfying ().

  Returning to step S1, if the operation of the vehicle control system 10 is not continued (step S1: NO), the operation of the vehicle control system 10 is terminated. Thereby, the anti-theft property in the automatic opening and closing of the door 30 and the convenience in emergency can be made compatible.

A door automatic opening and closing device 36 that can be automatically opened and closed is included, and in [8] control step (S7), the smartphone is provided on the condition that the door 30 is being opened and closed. 4 accepts an instruction operation using the wearable terminal 16 even though in limits 94 performs control to reverse action to stop or automatic door openers 36 the operation of the automatic door opening and closing device 36.

  As described above, in principle, the operation control of the in-vehicle device 26 is restricted when the smartphone 14 is within the restriction range 94, but the wearable terminal 16 has an exceptional condition that the door 30 is being opened and closed. Since the door automatic opening / closing device 36 is stopped or reversely operated in response to the command operation using, the anti-theft property and the emergency convenience in the automatic opening / closing of the door 30 can be achieved.

  In addition, when the in-vehicle communication device 20 can wirelessly communicate with an external device using a plurality of communication methods having different communication limit distances, communication using a communication method (BT communication) having a relatively long communication limit distance. The possible range may be set as “communication range 80”, and the communicable range by the communication method (LF communication) having a relatively short communication limit distance may be set as “permitted range 86”.

[Modification of operation]
Next, a modified example of the operation by the vehicle control system 10 will be described with reference to the flowchart of FIG. 7 and FIG. Steps S11 to S13 in FIG. 7 correspond to steps S1 to S3 in FIG.

  In step S <b> 14 of FIG. 7, the smartphone 14 determines its own position in relation to the in-vehicle communication device 20. Specifically, the first terminal-side control unit 46 determines the magnitude relationship between the RSSI when receiving the status signal from the in-vehicle communication device 20 and the second threshold Th2 (> Th1). When RSSI> Th2 is satisfied (step S14: YES), it is determined that the smartphone 14 is within the permitted range 100, and the process proceeds to step S15.

  As shown in FIG. 8, the communication range 80 and the permission range 100 are formed substantially concentrically around the vehicle 12 (the in-vehicle communication device 20). In this case, the restriction range 102 corresponds to an annular range obtained by removing the permission range 100 from the communication range 80.

  In step S15, the remote operation processing unit 54 determines whether or not the command operation of the user U using the wearable terminal 16 has been accepted, similarly to step S4 of FIG. When this command operation has not been received yet (step S15: NO), the process returns to step S11, and steps S11 to S16 are repeated until the operation is received.

  On the other hand, returning to step S14, when Th1 <RSSI ≦ Th2 is satisfied (step S14: NO), it is determined that the smartphone 14 is within the restricted range 102, and the process proceeds to step S16.

  In step S <b> 16, the remote operation processing unit 54 receives the detection value of the vehicle state sensor 24 from the in-vehicle communication device 20 and determines whether the door 30 is in an opening / closing operation by capturing a change in the detection value over time. To do. If it is determined that the door 30 is not opening and closing (step S16: NO), the process returns to step S11. That is, it is noted that the integrated control unit 28 does not receive a command signal in principle when the smartphone 14 is within the restricted range 102, and thus operation control of the in-vehicle device 26 is restricted.

  However, if it is determined that the door 30 is in an opening / closing operation (step S16: YES), the process proceeds to step S15 as an exception, and the remote operation processing unit 54 accepts a command operation of the user U using the wearable terminal 16. It is determined whether or not. When the command operation is accepted (step S15: YES), the process proceeds to step S17.

  In step S17, the remote operation processing unit 54 performs remote operation processing according to the command operation received in step S15. Specifically, the remote operation processing unit 54 transmits a command signal for performing remote operation of the in-vehicle device 26 to the outside via the first terminal side communication unit 40. The paired and connected vehicle 12 (integrated control unit 28) receives a command signal via the in-vehicle communication device 20.

  In step S <b> 18, the integrated control unit 28 controls the operation of the in-vehicle device 26 according to the content of the command signal, triggered by receiving the command signal in step S <b> 17. Note that the integrated control unit 28 performs stop control (or reverse operation control) of the automatic door opening / closing device 36 when the door 30 is in an opening / closing operation, even though the smartphone 14 is within the restricted range 102.

  Thus, paying attention to one communication method (BT communication), a range in which the RSSI when receiving a radio signal from the in-vehicle communication device 20 is higher than the second threshold Th2 (threshold) is set as “permitted range 100”. Then, a range in which the RSSI is lower than the second threshold Th2 may be set as a “restricted range”. Also with this configuration, as in the case shown in FIGS. 5 and 6, the above-described operational effects (coexistence of anti-theft and convenience) can be obtained.

[Remarks]
In addition, this invention is not limited to embodiment mentioned above, Of course, it can change freely in the range which does not deviate from the main point of this invention. Or you may combine each structure arbitrarily in the range which does not produce technical contradiction.
