Description

The present disclosure relates to opening/closing control of a vehicle door.

Conventionally, a vehicle equipped with an automatic door opening/closing mechanism is known. For example, the door of the rear seat is a slide opening/closing type door (hereinafter, referred to as “slide door”), and when a predetermined switch provided on the slide door is operated, the opening or closing operation of the slide door is performed. A vehicle having a configuration to be performed is known (see Patent Document 1).

JP, 2011-241621, A

In a vehicle equipped with an automatic door opening/closing mechanism, for example, a passenger such as a child accidentally operates a switch provided on the sliding door, and the opening/closing operation of the sliding door is performed in a situation where the driver does not know. This may cause a problem that the driver cannot handle. When the driver leaves the vehicle and the passenger left in the vehicle operates the switch to close the sliding door, the driver cannot detect the closing operation and stops the sliding door. There is a possibility that it is not possible to take measures such as causing the passenger to move away from the sliding door. Even if the driver outside the vehicle notices the closing operation of the slide door, the closing operation may be completed before returning to the vehicle and confirming safety, and the driver may not be able to respond in time. These problems are common not only to the sliding door but also to the automatic opening/closing operation of other doors of the vehicle such as a trunk or a hatch at the rear of the vehicle. For this reason, there is a demand for a technique that can prevent the driver from being too late when the vehicle door is closed by the automatic opening/closing mechanism.

The present disclosure can be realized as the following modes.

According to one aspect of the present disclosure, opening and closing of the doors (151, 152) of the vehicle (100) in which the in-vehicle device is mounted in the vehicle electronic key system (500) including the in-vehicle device and the portable device (200). A controller (10) for controlling is provided. The control device instructs to receive a closing operation instruction signal, which is a signal indicating the closing operation instruction, when an operation indicating the closing operation of the door is executed in the operation unit (310) provided in the vehicle. The signal receiving unit (113) is an external space continuous from the outer surface of the door among the plurality of LF antennas (21-25) provided in the vehicle when the closing operation instruction signal is received. A predetermined identification including an external LF antenna (21) having at least a wireless output range in an external space (Ar211) on the side including the door on the left and right of the central axis (CX) in the longitudinal direction of the vehicle. An LF transmission control unit (112) for transmitting an LF wireless signal from the LF antenna (21, 23-25) and a case where the portable device receives the LF wireless signal and transmits an RF wireless signal as a response signal. An RF reception control unit (111) that receives the RF wireless signal via an RF antenna (41) provided in the vehicle, and an actuator control device (300) that controls an actuator (320) for opening and closing the door. A closing operation control unit (114) for instructing a closing operation of the door, the closing operation control unit transmitting and receiving the LF radio signal and the reception of the RF radio signal from the specific LF antenna. When the result is a predetermined transmission/reception result indicating that the portable device does not exist in the external space, the actuator control device is not instructed to perform the closing operation, or the closing operation is being executed. Instruct to stop.

According to the control device of this aspect, when the transmission/reception result of the transmission of the LF wireless signal and the reception of the RF wireless signal from the specific LF antenna is a predetermined transmission/reception result indicating that the portable device does not exist in the external space. Does not instruct the actuator control device to perform the closing operation, or instructs the actuator control device to stop the closing operation that is being executed, so that the closing operation is started when the driver holding the portable device is not in the external space. It is possible to prevent the closing operation or the closing operation from being continuously executed and completed. Therefore, when the door of the vehicle is closed by the automatic opening/closing mechanism, it is possible to prevent the driver's response from being delayed.

The present disclosure can be realized in various forms other than the control device. For example, a vehicle equipped with a vehicle door opening/closing device, a control device or a vehicle door opening/closing device, a method for controlling the closing operation of a vehicle door, a computer program for implementing the method, and a storage storing the computer program. It can be realized in the form of a medium or the like.

A. First embodiment:
A1. Device configuration:
The vehicle electronic key system 500 shown in FIG. 1 (hereinafter also simply referred to as “electronic key system 500”) realizes a remote keyless entry and a smart entry. The remote keyless entry means a function/service in which when a user of the vehicle 100 operates a switch (not shown) of the portable device 200, the door of the vehicle 100 is opened/closed, unlocked, locked, etc. according to the operation. Further, the smart entry is a door when the user of the vehicle 100 carries the portable device 200 and enters a wireless communication area near the vehicle 100, or when the door of the vehicle is touched after the entry. Means to unlock the engine or to start the engine by the user sitting in the driver's seat and operating a predetermined switch while carrying the portable device 200. The electronic key system 500 includes a portable device 200, a control device 10 as a so-called on-vehicle device, an RF antenna 41, and five LF antennas 21, 22, 23, 24, 25. The electronic key system 500 also includes the RF reception circuit 51 shown in FIG. 2 and five LF transmission circuits 31, 32, 33, 34, and 35. In FIG. 1, the RF receiving circuit 51 and the five LF transmitting circuits 31 to 35 are omitted for convenience of illustration.

The portable device 200 is carried and used by a user as an electronic key for the vehicle 100. The portable device 200 has a configuration for transmitting a signal in the RF band (for example, 300 MHz to 400 MHz) (hereinafter, referred to as “RF signal”) in addition to an operation switch (not shown) and an LF band (30 kHz to 300 kHz). ) Signal (hereinafter, referred to as “LF signal”). As a configuration for transmitting the RF signal, for example, an antenna, an amplification circuit, a modulation circuit, a control IC (Integrated Circuit), or the like is applicable. As a configuration for receiving the LF signal, for example, an antenna, a low noise amplifier, a demodulation circuit, a control IC, and the like are applicable. The RF signal corresponds to a subordinate concept of the RF wireless signal in the present disclosure. Further, the LF signal corresponds to a subordinate concept of the LF wireless signal in the present disclosure.

When the portable device 200 receives the LF signal from the vehicle 100, the portable device 200 transmits an RF signal including a preset identifier (ID) as a response to the LF signal. At this time, so-called challenge-response authentication is performed. The exchange of the LF signal and the RF signal will be described later. In the present embodiment, the portable device 200 is a dedicated device used as an electronic key for a vehicle. The portable device 200 may be configured by any type of wireless communication device such as a smartphone.

As shown in FIG. 2, the control device 10 is configured by an ECU (Electronic Control Unit) including a CPU (Central Processing Unit) 11, a memory 12, a CAN (Controller Area Network) communication unit 13, and a timer 14. ing. The CPU 11 executes a control program stored in advance in the memory 12 to thereby cause the RF reception control unit 111, the LF transmission control unit 112, the instruction signal reception unit 113, the closing operation control unit 114, and the electronic key system control unit. Function as 115.

The RF reception control unit 111 controls the reception of the RF signal via the RF antenna 41 and the RF reception circuit 51. The LF transmission control unit 112 controls transmission of LF signals via the LF antennas 21 to 25 and the LF transmission circuits 31 to 35. Details of the instruction signal receiving unit 113 and the closing operation control unit 114 will be described later. The electronic key system control unit 115 performs authentication processing of the portable device 200, transmission of unlocking and opening/closing instructions to a power slide door (PSD) control device 300, which will be described later, and other door control devices (not shown). Controls remote keyless entry and smart entry. The timer 14 performs timekeeping processing. In this embodiment, the timer 14 is composed of an IC. The timer 14 may be realized as a function of the CPU 11.

The CAN communication unit 13 controls communication via the CAN 60. As a result, the control device 10 can exchange data with other control devices. As an example of “another control device”, a power slide door control device 300 is shown in FIG.

The power slide door control device 300 controls the door opening/closing actuator 320 that opens/closes the left rear door 151 and the right rear door 152 shown in FIG. 1. The door opening/closing actuator 320 is configured by, for example, a motor that slides the door, a link mechanism, or the like. The above-described door opening/closing actuator 320 and the operation unit 310 are electrically connected to the power slide door control device 300 by a dedicated line. The operation unit 310 includes a switch for instructing an opening operation or a closing operation of the left rear door 151 and the right rear door 152, and a switch for instructing locking or unlocking of the left rear door 151 and the right rear door 152. It is provided. The power slide door control device 300 notifies the vehicle 100 of the open/closed state of the left rear door 151 and the right rear door 152 via the CAN 60. Further, the power slide door control device 300 is a signal (hereinafter, referred to as a “closing operation instruction signal”, which is transmitted from the operation unit 310 instructing the closing operation of the left rear door 151 or the right rear door 152, in response to the closing operation of the operating unit 310. ") is received, the door opening/closing actuator 320 is controlled to start the door closing operation, and at the same time, the closing operation instruction signal is transmitted to the control device 10 via the CAN 60. The power slide door control device 300 corresponds to a subordinate concept of the actuator control device in the present disclosure.

The RF antenna 41 is an antenna for receiving an RF signal, and is arranged in the vehicle interior of the vehicle 100 near a rear seat. The RF antenna 41 may be arranged at another position in the vehicle 100.

The five LF antennas 21 to 25 are all antennas for transmitting LF signals, and are arranged in a distributed manner in the vehicle 100. Specifically, as shown in FIG. 1, the first vehicle exterior LF antenna 21 is arranged on the outer handle portion of the left rear door 151 of the vehicle 100. The second vehicle exterior LF antenna 22 is arranged on the outer handle portion of the right rear door 152 of the vehicle 100. The first in-vehicle LF antenna 23 is arranged between the driver's seat and the passenger seat in the vehicle interior of the vehicle 100. The second in-vehicle LF antenna 24 is arranged between the front seat and the rear seat in the vehicle interior of the vehicle 100. The third in-vehicle LF antenna 25 is arranged between the rear seat and the trunk room. The two outside LF antennas 21 and 22 set a predetermined range outside and inside the vehicle 100 as a wireless output range. On the other hand, the three LF antennas 23 to 25 set the wireless output range within a predetermined range in the vehicle interior of the vehicle 100. Details of the wireless output range of each LF antenna 21 to 25 will be described later.

The RF receiving circuit 51 is electrically connected to the RF antenna 41 and the control device 10. The RF receiving circuit 51 amplifies and encodes the RF signal received by the RF antenna 41, and outputs it to the RF reception control unit 111 as a digital signal. The LF transmission circuit 31 is electrically connected to the LF antenna 21 and the control device 10. Similarly, the LF transmission circuit 32 is used for the second vehicle exterior LF antenna 22 and the control device 10, the LF transmission circuit 33 is used for the first vehicle interior LF antenna 23 and control device 10, and the LF transmission circuit 34 is used for the second vehicle interior LF antenna 24 and control device. The device 10 and the LF transmission circuit 35 are electrically connected to the third in-vehicle LF antenna 25 and the control device 10, respectively. The LF transmission circuits 31 to 35 modulate and amplify the digital signals output from the control device 10 and output LF radio waves via the LF antennas 21 to 25.

The left rear door 151 and the right rear door 152 are both configured as so-called power slide doors, and the door opening/closing actuator 320 automatically performs the opening operation and the closing operation. In the vehicle 100, the power slide door control device 300, the operation unit 310, and the door opening/closing actuator 320 described above constitute an automatic opening/closing mechanism for the left rear door 151 and the right rear door 152.

Here, the wireless output range of each of the LF antennas 21 to 25 will be described with reference to FIG. The wireless output range of the first LF antenna 21 outside the vehicle is a substantially spherical area Ar21 centered on the LF antenna 21. The region Ar21 is formed both inside and outside the vehicle 100. In FIG. 3, the external space Ar211 that is a part of the region Ar21 is hatched for convenience of illustration. The external space Ar211 is a space continuous from the outer surface of the left rear door 151, and means a space on the left or right side of the central axis CX in the longitudinal direction of the vehicle 100, which side includes the left rear door 151. The external space continuous from the outer surface of the door that is the target of the closing operation based on the operation of the operation unit 310 (hereinafter, referred to as the “operation target door”) corresponds to a subordinate concept of the external space in the present disclosure. Further, of the two vehicle exterior LF antennas 21 and 22, the LF antenna having at least the wireless output range in the external space corresponds to a subordinate concept of the external LF antenna in the present disclosure.

The wireless output range of the second vehicle exterior LF antenna 22 is a substantially spherical area Ar22 centered on the second vehicle exterior LF antenna 22. The region Ar22 is formed over the outside and inside of the vehicle 100, similarly to the region Ar21 described above. In the example of FIG. 3, the portable device 200 exists in the area Ar22. The size of the area Ar22 is substantially equal to the size of the area Ar21 described above. In addition, the area Ar22 includes an external space like the external space Ar211 described above.

The wireless output range of the first in-vehicle LF antenna 23 is a substantially spherical area Ar23 centered on the first in-vehicle LF antenna 23. The area Ar23 is an area including the driver's seat and the passenger seat in the vehicle interior of the vehicle 100.

The wireless output range of the second in-vehicle LF antenna 24 is a substantially spherical area Ar24 centered on the second in-vehicle LF antenna 24. The region Ar24 is a region including a part of the front seats (driver's seat and passenger seat) and a part of the rear seats in the vehicle interior of the vehicle 100.

The wireless output range of the third in-vehicle LF antenna 25 is a substantially spherical area Ar25 centered on the third in-vehicle LF antenna 25. The area Ar25 is an area from the rear seat to the trunk room in the vehicle interior of the vehicle 100.

Each of the wireless output ranges (areas) Ar21 to Ar25 described above can be received with a signal strength (received signal strength: RSSI) that allows the LF signal output from each LF antenna 21 to 25 to be demodulated by the portable device 200. Means a range. Such a range is controlled to have a predetermined size by adjusting the electric power supplied to each of the LF antennas 21 to 25.

In the vehicle 100, the control device 10 uses the portable device 200, the RF antenna 41, the five LF antennas 21 to 25, the RF receiving circuit 51, and the five LF transmitting circuits 31 to 35 included in the vehicle electronic key system 500. Then, a closing operation control process, which will be described later, for controlling the closing operation of the left rear door 151 and the right rear door 152 is executed. By performing the closing operation control process, it is possible to prevent the driver from being too late when the left rear door 151 and the right rear door 152 perform the closing operation. For example, as shown in FIG. 3, in a state where the driver M1 carries the portable device 200 and gets out of the vehicle 100 while the passenger M2 is in the rear seat, the passenger M2 operates the operation unit 310. When the driver M1 notices that he/she is operating to open the left rear door 151 and then operating the operation part 310 to close the left rear door 151, in the conventional technique, the driver M1 rushes to the left rear door. Even if the driver heads for the door 151, the driver M1 may not be able to respond in time. However, in the present embodiment, it is possible to prevent the driver M1 from failing to respond in time because the control device 10 executes the later-described closing operation control process.

A2. Close operation control process:
The closing operation control process shown in FIG. 4 is started when the start switch of the vehicle 100 is turned on. The instruction signal receiving unit 113 determines whether or not a closing operation instruction signal has been received from the power slide door control device 300 (step S105). When it is determined that the closing operation instruction signal is not received (step S105: NO), step S105 is executed again.

When it is determined that the closing operation instruction signal has been received (step S105: YES), the LF transmission control unit 112 activates the timer 14 (step S110). A predetermined period is set in the timer 14 as a period for transmitting the LF signal.

The LF transmission control unit 112 transmits an LF signal from the LF antenna outside the vehicle on the same side as the operation target door (step S115). The same side as the operation target door means the same side as the operation target door on the left and right of the central axis CX of the vehicle 100 shown in FIG. 3. For example, as shown in FIG. 3, when the occupant M2 operates the left operation unit 310, the left rear door 151 corresponds to the operation target door, and the first exterior LF antenna 21 indicates that “the operation target door is on the same side as the operation target door”. It corresponds to "outside LF antenna".

As shown in FIG. 4, the LF transmission control unit 112 determines whether or not an RF signal has been received from the portable device 200 (step S120). More specifically, in step S115, a wake signal is transmitted as the LF signal. On the other hand, the portable device 200 transmits, as an RF signal, an ACK (ACK) signal which is a response signal including no authentication information. When receiving the ACK signal, the LF transmission control unit 112 transmits a challenge (CLG) signal as the LF signal. This challenge signal includes a challenge code used in so-called challenge-response authentication. Upon receiving the challenge signal, the portable device 200 transmits a response (RES) signal to the challenge code as an RF signal. Here, the RF signal (RES signal) includes authentication information. The RF reception control unit 111 passes the received RF signal (RES signal) to the electronic key system control unit 115. The electronic key system control unit 115 performs an authentication process on the signal passed from the RF reception control unit 111, and if the authentication is successful, notifies the LF transmission control unit 112 of that fact. In this case, the LF transmission control unit 112 determines that the RF signal has been received from the portable device 200. When it is determined that the RF signal (ACK signal and RES signal) is not received from the portable device 200 (step S120: NO), the LF transmission control unit 112 determines whether the timer has expired (step S125), When it is determined that the timer has not expired (step S125: NO), the process returns to step S115. Therefore, in this case, the LF signal is transmitted again. It should be noted that steps S115, S120, and S125 described above can be said to be processing for detecting the presence of the portable device 200 targeting the LF antenna outside the vehicle on the same side as the operation target door (hereinafter referred to as "portable device detection processing").

For example, when the portable device 200 does not exist in the area Ar21 as in the example shown in FIG. 3, the LF signal transmitted from the first vehicle exterior LF antenna 21 is not received by the portable device 200. Therefore, it is determined that the portable device 200 does not transmit the RF signal and does not receive the RF signal from the portable device 200 in step S120 described above. In the example shown in FIG. 3, the RF signal is not received from the portable device 200 even if the step S115 is repeatedly executed. Therefore, it is eventually determined that the timer has expired in step S125. As shown in FIG. 4, when it is determined that the timer has expired (step S125: YES), the closing operation control unit 114 instructs the power slide door control device 300 to stop the closing operation (step S130). .. In this case, when the power slide door control device 300 receives an instruction to stop the closing operation from the control device 10, the power sliding door control device 300 controls the door opening/closing actuator 320 to stop the closing operation of the left rear door 151. In the example shown in FIG. 3, even if the occupant M2 operates the operation unit 310 and the left rear door 151 starts the closing operation, the closing operation is stopped. For this reason, it is possible to prevent the driver M1 from being on the opposite side of the left rear door 151, and not being able to keep up with the driver when he notices the closing operation of the left rear door 151 and returns to the vehicle 100. The "correspondence" corresponds to, for example, an action of stopping the closing operation of the left rear door 151 or an action of separating the passenger M2 from the left rear door 151. As shown in FIG. 4, after completion of step S130, the process returns to step S105.

Unlike the example shown in FIG. 3, when the portable device 200 exists in the area Ar21, the portable device 200 receives the LF signal transmitted from the first LF antenna 21 outside the vehicle, and transmits the RF signal as a response. .. Therefore, in this case, it is determined that the RF signal is received from the portable device 200 in step S120 described above.

As shown in FIG. 4, when it is determined that the RF signal is received in the above step S120 (step S120: YES), the portable device detection process for the first in-vehicle LF antenna 23 is executed (step). S135). Specifically, as shown in FIG. 5, the LF transmission control unit 112 activates the timer 14 (step S205). The LF transmission control unit 112 transmits the LF signal from the target in-vehicle LF antenna, in this case, the first in-vehicle LF antenna 23 (step S210). The LF transmission control unit 112 determines whether or not an RF signal has been received from the portable device 200 (step S215). When it is determined that the RF signal is not received from the portable device 200 (step S215: NO), the LF transmission control unit 112 determines whether the timer has expired (step S220), and the timer has not expired. If determined (step S220: NO), the process returns to step S210. Therefore, in this case, the LF signal is transmitted again from the first in-vehicle LF antenna 23.

When it is determined that the RF signal is received in the above step S215 (step S215: YES), the above step S130 shown in FIG. 4 is executed. Therefore, in this case, the closing operation of the operation target door is stopped. For example, as shown in FIG. 6, the driver M1 is sitting in the driver's seat, and the passenger M2 operates the external handle of the left rear door 151 outside the vehicle 100 to start the closing operation of the left rear door 151. In this case, since the portable device 200 exists in the area Ar23 and the area Ar21, it is determined that the RF signal is received in step S215. Therefore, step S130 is executed, and the closing operation of the left rear door 151 is stopped. Therefore, even if the driver M1 notices the closing operation of the left rear door 151, opens the door of the driver's seat, gets off the vehicle, and heads to the left rear door 151, it is possible to prevent the response from being delayed. Note that, unlike the example of FIG. 6, even when the passenger M2 operates the operation unit 310 while riding in the rear seat, the same processing is performed when the driver M1 is sitting in the driver seat. .. In such a case, the driver M1 needs to turn around and remove his or her seat belt to move to the rear seat, which may delay the response. Therefore, step S130 is executed and the left rear door 151 is closed. I'm trying to stop it.

As shown in FIG. 5, when it is determined in step S220 that the timer has expired (step S220: YES), step S140 shown in FIG. 4 is executed. In step S140, the portable device detection process for the second in-vehicle LF antenna 24 is executed. This step S140 differs from step S135 described above only in that the target LF antenna is changed from the first in-vehicle LF antenna 23 to the second in-vehicle LF antenna 24. Therefore, in step S210 shown in FIG. 5, the LF signal is output from the second in-vehicle LF antenna 24. In this step S140, when the portable device 200 exists in the area Ar24, the above-described step S130 is executed to stop the closing operation of the operation target door. When the driver M1 is seated in the rear seat, even if he/she notices the closing operation of the left rear door 151, it takes time to remove his/her own seed belt, or the operation unit 310 or the left rear door 151 is operated. It is assumed that it will be difficult to extend. However, even in such a situation, since the closing operation of the left rear door 151 is stopped, it is possible to prevent the driver M1 from being late for the response.

When it is determined that the timer has expired in step S220 in the portable device detection process for the second in-vehicle LF antenna 24 (step S220: YES), step S145 shown in FIG. 4 is executed.

In step S145, the portable device detection process for the third in-vehicle LF antenna 25 is executed. This step S140 differs from step S135 described above only in that the target LF antenna is changed from the first in-vehicle LF antenna 23 to the third in-vehicle LF antenna 25. Therefore, in step S210 shown in FIG. 5, the LF signal is output from the third in-vehicle LF antenna 25. In step S145, when the portable device 200 is present in the area Ar25, the above step S130 is executed to stop the closing operation of the operation target door. When the driver M1 is in the vicinity of the luggage compartment, even if he/she notices the closing operation of the left rear door 151, it is difficult to reach the operation unit 310 or the left rear door 151, or the outside of the vehicle 100 reaches the left rear door 151. It is assumed that it will take a long time. However, even in such a situation, since the closing operation of the left rear door 151 is stopped, it is possible to prevent the driver M1 from being late for the response.

When it is determined in step S220 in the portable device detection process for the third in-vehicle LF antenna 25 that the timer has expired (step S220: YES), the process returns to step S105 as shown in FIG. Therefore, in this case, the closing operation of the operation target door is not stopped. The case where it is determined that the timer has expired in step S220 of the portable device detection process (step S145) for the third in-vehicle LF antenna 25 means that the portable device 200 exists in the external space Ar211 shown in FIG. Corresponds to. That is, since the portable device 200 exists in the external space Ar211, the control device 10 transmits the RF signal, which is a response signal, to the LF signal transmitted from the first external LF antenna 21. Can receive. On the other hand, since the portable device 200 does not exist inside the vehicle 100, even if any of the in-vehicle LF antennas 23 to 25 transmits the LF signal, the portable device 200 does not transmit the RF signal which is the response signal. Therefore, the timer expires in step S220 of the portable device detection process for the in-vehicle LF antennas 23, 24, 25. Then, in such a case, step S130 is not executed. Therefore, the closing operation of the operation target door (the left rear door 151) is not stopped. When the portable device 200 exists in the external space Ar211, it is highly possible that the driver M1 also exists in the external space Ar211. In this situation, even if the closing operation of the left rear door 151 is started, the driver M1 does not need to remove his or her own seat belt, and it does not take a long time to reach the left rear door 151. Therefore, the response of the driver M1 will not be delayed. In addition, since the closing operation of the left rear door 151 is not stopped, it is possible to prevent the closing operation of the left rear door 151 from being unnecessarily stopped and the time until the closing operation of the left rear door 151 is completed, which is convenient. Can be suppressed.

The processing of the control device 10 in the above closing operation control processing is summarized as follows. That is, the control device 10 outputs the LF signals from the external LF antenna (for example, the first vehicle exterior LF antenna 21) having at least the wireless output range in the external space on the side including the operation target door, and the vehicle interior LF antennas 23 to 25. And the presence/absence of reception of an RF signal as a response is specified, and the transmission/reception result of the transmission of the LF signal and the reception of the RF signal indicates that the portable device 200 exists in the external space (for example, external space Ar211). In the case of the following predetermined results (i) and (ii) indicating that the closing operation is not performed, the power slide door control device 300 is instructed to stop the closing operation.
(I) No RF signal is received within a predetermined period with respect to the transmission of the LF signal from the external LF antenna that has at least the external space on the side including the operation target door as the wireless output range.
(Ii) For the transmission of the LF signal from the external LF antenna whose wireless output range is at least the external space on the side including the operation target door, the RF signal is received within a predetermined period, and the three in-vehicle LFs are received. For the transmission of the LF signal from any of the in-vehicle LF antennas among the antennas 23 to 25, there is reception of the RF signal within a predetermined period.
The external LF antenna (first external LF antenna 21) having at least the external space on the side including the operation target door as the wireless output range in the present embodiment and all the in-vehicle LF antennas 23 to 25 are specified in the present disclosure. It corresponds to a subordinate concept of the LF antenna.

The sequence of each functional unit when the above closing operation control process is executed will be described with reference to FIGS. 7 to 9.

FIG. 7 is a sequence diagram when the portable device 200 exists in the external space Ar211. When a closing operation is performed in the operation unit 310 for the left rear door 151 and the closing operation is detected by the power slide door control device 300, the power slide door control device 300 controls the door opening/closing actuator 320 to the left side. The closing operation of the rear door 151 is started and the closing operation instruction signal is transmitted to the control device 10.

The control device 10 activates the timer 14 and transmits the LF signal from the LF antenna 21. The portable device 200 receives the LF signal transmitted from the LF antenna 21, and transmits an RF signal as a response. When the RF signal is received by the RF antenna 41, the electronic key system control unit 115 (not shown in FIG. 7) performs the authentication, and the fact that the authentication is successful (RF signal reception notification) is transmitted to the control device 10. .. The control device 10 transmits the LF signal from each of the in-vehicle LF antennas in the order of the first in-vehicle LF antenna 23, the second in-vehicle LF antenna 24, and the third in-vehicle LF antenna 25. However, since the portable device 200 exists in the external space Ar211 and does not exist in the three regions Ar22, Ar23, and Ar24, the LF signal is not received by the portable device 200, and therefore, the portable device 200 at the RF antenna 41. No RF signal is received from the timer 14 and the timer 14 expires. Therefore, in this case, the closing operation stop instruction is not transmitted from the control device 10 to the power slide door control device 300.

FIG. 8 is a sequence diagram when the portable device 200 does not exist in the area Ar21. FIG. 8 illustrates a sequence of a situation in which the driver M1 is outside the vehicle 100, is on the side opposite to the operation target door, and the portable device 200 is present in the area Ar22, as shown in FIG. 3, for example. There is.

In this situation, even if the LF signal is transmitted from the first outside-vehicle LF antenna 21, the portable device 200 cannot receive the LF signal. Therefore, the timer 14 expires and the closing operation stop instruction is transmitted from the control device 10 to the power slide door control device 300. As a result, the power slide door control device 300 controls the door opening/closing actuator 320 to stop the closing operation of the left rear door 151.

FIG. 9 is a sequence diagram when the portable device 200 exists in the overlapping area of the area Ar21 and the area Ar23. FIG. 9 shows a sequence in the situation shown in FIG. 6, for example. In this situation, the portable device 200 receives the LF signal transmitted from the first LF antenna outside the vehicle 21, and transmits the RF signal as a response. When the RF signal is received by the RF antenna 41, the electronic key system control unit 115 (not shown in FIG. 9) performs authentication, and a notification of successful authentication (RF signal reception notification) is transmitted to the control device 10. .. In this case, the control device 10 first transmits the LF signal from the first in-vehicle LF antenna 23 among the three in-vehicle LF antennas 23 to 25. The portable device 200 receives the LF signal transmitted from the first in-vehicle LF antenna 23, and transmits an RF signal in response to the LF signal. When the RF signal is received by the RF antenna 41, the electronic key system control unit 115 (not shown in FIG. 9) performs authentication, and a notification of successful authentication (RF signal reception notification) is transmitted to the control device 10. .. In this case, the control device 10 transmits a closing operation stop instruction to the power slide door control device 300, and the closing operation of the left rear door 151 is stopped.

According to the control device 10 of the first embodiment described above, the transmission and reception results of the transmission of the LF signal and the reception of the RF signal from the specific LF antenna (the first vehicle exterior LF antenna 21 and all vehicle interior LF antennas 23 to 25) are performed. If the portable device 200 has a predetermined transmission/reception result (above (i) or (ii)) indicating that the portable device 200 does not exist in the external space Ar 211, the power slide door control device 300 is closed. Since the instruction to stop the operation is made, it is possible to prevent the closing operation from being continuously executed and completed when the driver carrying the portable device 200 is not in the external space Ar211. Therefore, when the door of the vehicle is closed by the automatic opening/closing mechanism, it is possible to prevent the driver's response from being delayed.

Further, as a predetermined transmission result, (i) the RF signal is transmitted within a predetermined period with respect to the transmission of the LF signal from the external LF antenna whose wireless output range is at least the external space on the side including the operation target door. Since the result that there is no reception is included, it is possible to accurately specify that the driver M1 and the portable device 200 are not present in the external space Ar211.

In addition, as a predetermined transmission result, (ii) the transmission of the LF signal from the external LF antenna whose wireless output range is at least the external space on the side including the operation target door, the RF signal of the RF signal is transmitted within a predetermined period. The result includes that there is reception and that the RF signal is received within a predetermined period with respect to the transmission of the LF signal from any one of the three in-vehicle LF antennas 23 to 25. Therefore, it is possible to accurately specify that the driver M1 is not present in the external space Ar211 together with the portable device 200.

Further, when the reception result of the transmission of the LF signal and the reception of the RF signal from the specific LF antenna is not a predetermined transmission/reception result indicating that the portable device 200 does not exist in the external space Ar 211, that is, the portable device 200 is an external device. If the transmission/reception result indicates that the space Ar211 is present, the control device 10 does not instruct the power slide door control device 300 to stop the closing operation that is being executed, and thus the useless closing operation is stopped. By doing so, it is possible to prevent the time until the closing operation of the left rear door 151 from being completed from increasing, and it is possible to suppress the loss of convenience.

B. Second embodiment:
The control device 10 of the second embodiment differs from the control device 10 of the first embodiment in the detailed procedure of the closing operation control process. The configurations of the control device 10 and the vehicle electronic key system 500 of the second embodiment are the same as those of the control device 10 and the vehicle electronic key system 500 of the first embodiment. And detailed description thereof will be omitted. The memory 12 of the control device 10 of the second embodiment stores a first threshold strength and a second threshold strength, which will be described later, in advance.

As shown in FIGS. 10 and 11, in the closing operation control process of the second embodiment, step S120a is executed instead of step S120, and steps S155, S160, and S165 are replaced with steps S135, S140, and S145. , S167, S170, and S175 are different from the closing operation control process of the first embodiment. The other procedures of the closing operation control process of the second embodiment are the same as those of the closing operation control process of the first embodiment, so the same steps are denoted by the same reference numerals and detailed description thereof will be omitted. In the first embodiment, first, when the portable device detection process (steps S115 to S125) is performed for the first vehicle exterior LF antenna 21 and no RF signal (RES signal) is received, the first vehicle interior LF antenna 23, The portable device detection process is sequentially performed in the order of the second in-vehicle LF antenna 24 and the third in-vehicle LF antenna 25. On the other hand, in the second embodiment, the procedure for collectively detecting the presence of the portable device is executed for the three in-vehicle LF antennas 23 to 25. The details will be described below.

As described in the first embodiment, in step S115 shown in FIG. 10, the LF transmission control unit 112 transmits the WAKE signal as the LF signal. In the procedure described later, the CLG signal is transmitted, and the transmission of the CLG signal is clearly shown in FIG. 10. Therefore, in FIG. 10, the RF signal transmitted in step S115 is a “WAKE” signal. It is clearly stated.

After performing step S115, the LF transmission control unit 112 determines whether or not an ACK signal has been received from the portable device 200 (step S120a). In step S120 of the first embodiment, not only the ACK signal is received, but also the RES signal is received after that, and it is determined that “the RF signal is received from the portable device 200” when the authentication is successful. In step S120a of the second embodiment, only the presence or absence of the reception of the ACK signal is determined.

When it is determined that the ACK signal is not received (step S120a: NO), the above step S125 is executed. On the other hand, when it is determined that the ACK signal is received (step S120a: YES), the LF transmission control unit 112 determines that the outside LF antenna on the same side as the operation target door (transmits the WAKE signal in step S115). The CLG signal and the burst (BRST) signal are transmitted as LF signals from the same LF antenna outside the vehicle (step S155). The BRST signal means a signal obtained by directly outputting a carrier wave for a short time without modulating the carrier wave. As shown in FIG. 6, when the operation target door is the left rear door 151, the CLG signal and the BRST signal are transmitted from the first vehicle exterior LF antenna 21.

The LF transmission control unit 112 transmits the BRST signal as an LF signal from each in-vehicle LF antenna in the order of the first in-vehicle LF antenna 23, the second in-vehicle LF antenna 24, and the third in-vehicle LF antenna 25 (step S155).

Here, the portable device 200 performs a process different from that of the above-described first embodiment. Specifically, the portable device 200 waits until it receives a BRST signal from all the in-vehicle LF antennas after receiving the WAKE signal from the in-vehicle LF antenna, and when receiving the BRST signal from all the in-vehicle LF antennas. The value of the received signal strength (RSSI) of the BRST signal received from the LF antenna outside the vehicle and each LF antenna inside the vehicle is transmitted as an RF signal together with the RES signal.

In the control device 10, the LF transmission control unit 112 determines whether or not the RES signal and the signal indicating the value of the RSSI (hereinafter, referred to as “RSSI signal”) are received from the portable device 200 (step S165). When it is determined that the RES signal and the RSSI signal are not received from the portable device 200 (step S165: NO), the LF transmission control unit 112 determines whether the timer has expired (step S167). When it is determined that the timer has not expired (step S167: NO), the process returns to step S155 described above. Therefore, in this case, the transmission of the channel signal and the burst signal (steps S155 and S160) is executed. When it is determined that the timer has expired (step S167: YES), the above step S130 is executed and the closing operation of the operation target door is stopped, as shown in FIG. For example, when a portable device for a vehicle different from the vehicle 100 exists near the vehicle 100 and the portable device 200 (driver M1) does not exist near the vehicle 100, the timer expires and the operation target The closing operation of the door will be stopped.

When it is determined in step S165 described above that the RES signal and the RSSI signal are received from the portable device 200 (step S165: YES), the LF transmission control unit 112 converts the received RSSI signal into the received RSSI signal, as illustrated in FIG. Based on this, it is determined whether the RSSI of the BRST signal transmitted from the LF antenna outside the vehicle (first outside LF antenna 21) is equal to or higher than a predetermined first threshold strength (step S170). The first threshold strength is the RSSI of the BRST signal transmitted from the first external LF antenna 21 or the second external LF antenna 22 and received by the portable device 200 when the portable device 200 is present in the area Ar21 or Ar22. Is stored in the memory 12 in advance as a minimum value obtained by experiments.

When it is determined that the RSSI of the BRST signal transmitted from the LF antenna outside the vehicle is not equal to or higher than the first threshold strength (step S170: NO), the above step S130 is executed and the closing operation of the operation target door is stopped. When the RSSI of the BRST signal transmitted from the LF antenna outside the vehicle is not equal to or higher than the first threshold strength, it is highly possible that the portable device 200 does not exist in the area Ar21 or the area Ar22. In this case, by executing step S130, it is possible to prevent the driver M1 from failing to respond in time when the door of the vehicle 100 performs the closing operation.

When it is determined that the RSSI of the BRST signal transmitted from the LF antenna outside the vehicle is equal to or greater than the first threshold strength (step S170: YES), the LF transmission control unit 112 transmits the BRST transmitted from the LF antennas 23 to 25 inside the vehicle. It is determined whether all the RSSIs of the signals are less than the second threshold strength (step S175). The second threshold strength is the minimum value of the RSSIs of the BRST signals transmitted from the in-vehicle LF antennas 23 to 25 and received by the portable device 200 when the portable device 200 exists in the region Ar23 to the region Ar25, It is obtained in advance by experiments or the like and stored in the memory 12.

When none of the RSSIs of the BRST signals transmitted from the in-vehicle LF antennas 23 to 25 is less than the second threshold strength, in other words, among the RSSIs of the BRST signals transmitted from the in-vehicle LF antennas 23 to 25, When it is determined that at least one of the above is not less than the second threshold strength (step S175: NO), the above step S130 is executed and the closing operation of the operation target door is stopped. If at least one of the RSSIs of the BRST signals transmitted from the in-vehicle LF antennas 23 to 25 is not less than the second threshold strength, the portable device 200 is likely to be present in the vehicle compartment or the trunk room. In this case, by executing step S130, it is possible to prevent the driver M1 from failing to respond in time when the door of the vehicle 100 performs the closing operation.

When it is determined that the RSSIs of the BRST signals transmitted from the in-vehicle LF antennas 23 to 25 are all less than the second threshold strength (step S175: YES), the process returns to step S105. Therefore, in this case, step S130 is not executed and the closing operation of the operation target door is not stopped. When it is determined in step S175 that the RSSIs of the BRST signals transmitted from the in-vehicle LF antennas 23 to 25 are all less than the second threshold strength, the portable device 200 determines that the portable device 200 is the external space, for example, the external space in FIG. It is highly likely to be present in Ar211. In this case, the driver M1 is highly likely to be in the vicinity of the door to be operated, and thus it is unlikely that the driver M1 will not be in time when the door of the vehicle 100 performs the closing operation.

The sequence of each functional unit when the above-described closing operation control process of the second embodiment is executed will be described with reference to FIG.

FIG. 12 is a sequence diagram when the portable device 200 exists in the vicinity of the trunk room (in the area Ar21 and the area Ar25). For convenience of illustration, the timer activation process is omitted. When a closing operation is performed in the operation unit 310 for the left rear door 151 and the closing operation is detected by the power slide door control device 300, the power slide door control device 300 controls the door opening/closing actuator 320 to the left side. The closing operation of the rear door 151 is started and the closing operation instruction signal is transmitted to the control device 10.

The control device 10 activates the timer 14 and transmits the LF signal (WAKE signal) from the LF antenna 21. The portable device 200 receives the WAKE signal transmitted from the LF antenna 21, and transmits an RF signal (ACK signal) as a response. When the ACK signal is received via the RF antenna 41, the RF reception control unit 111, not shown in FIG. 12, notifies the control device 10 of the ACK signal reception.

The control device 10 transmits an LF signal (CLG signal and BRST signal) from the first vehicle exterior LF antenna 21. The control device 10 transmits the LF signal (BRST signal) from the first in-vehicle LF antenna 23, then transmits the LF signal (BRST signal) from the second in-vehicle LF antenna 24, and then the third in-vehicle LF. An LF signal (BRST signal) is transmitted from the antenna 25.

The portable device 200 receives the CLG signal and the BRST signal from the first vehicle exterior LF antenna 21, and transmits the RF signal (RES signal and RSSI signal) when receiving the BRST signal from each vehicle interior LF antenna 23 to 25. When the RES signal and the RSSI signal are received via the RF antenna 41, the RF reception control unit 111 not shown in FIG. 12 notifies the control device 10 of the reception of these signals.

The control device 10 compares the RSSI of the BRST signal transmitted from each LF antenna transmitted from the portable device 200 with the threshold strength, and the portable device 200 does not exist in the external space (for example, the external space Ar211). When the results are the following (iii) and (iV), which are determined in advance, the closing operation stop instruction is transmitted to the power slide door control device 300.
(Iii) The RSSI value at the time of receiving the LF signal (BRST signal) from the external LF antenna having at least the external space on the side including the operation target door as the wireless output range is not equal to or higher than the first threshold strength.
(IV) The RSSI value at the time of receiving the LF signal (BRST signal) from the external LF antenna whose wireless output range is at least the external space on the side including the operation target door is equal to or higher than the first threshold strength, and 3 The RSSI value at the time of receiving the LF signal (BRST signal) from one of the in-vehicle LF antennas 23 to 25 is not less than the second threshold strength.

When the power slide door control device 300 receives the closing operation stop instruction from the control device 10, the power sliding door control device 300 controls the door opening/closing actuator 320 to stop the closing operation of the left rear door 151.

The control device 10 of the second embodiment described above has the same effects as the control device 10 of the first embodiment. In addition, the received signal strength (RSSI) of the LF signal (BRST signal) transmitted from the vehicle exterior LF antenna (for example, the first vehicle exterior LF antenna 21) having at least the external space on the side including the operation target door as the wireless output range. Is less than a predetermined first threshold value, or the RSSI is equal to or higher than the first threshold strength and the LF transmitted from any one of the three in-vehicle LF antennas 23 to 25. When the reception intensity of the wireless signal is not less than the predetermined second threshold intensity, the actuator control device is instructed to stop the closing operation that is being executed. When there is a high possibility that the driver M1 cannot deal with the situation immediately, it is possible to instruct the power slide door control device 300 to stop the closing operation being executed.

C. Other embodiments:
(C1) In each embodiment, when the closing operation stop instruction is transmitted from the control device 10, the closing operation of the operation target door has already been started, but the present disclosure is not limited to this. The closing operation of the operation target door may be started when the closing operation stop instruction is not transmitted from the control device 10. In such a configuration, for example, the following operation may be performed. When the closing operation is performed in the operation unit 310, the power slide door control device 300 does not send the closing operation instruction signal to the power slide door control device 300, but sends the closing operation instruction signal to the control device 10. After that, the closing operation control process of each embodiment is executed. Then, when the power slide door control device 300 does not receive the closing operation stop instruction from the control device 10 within a predetermined period from the operation of the operation unit 310, the power sliding door control device 300 starts the closing operation of the operation target door. On the other hand, when the closing operation stop instruction is received within the predetermined period, the power slide door control device 300 does not start the closing operation (does not instruct the door opening/closing actuator 320 to perform the closing operation). Even in such a configuration, the same effect as that of each embodiment can be obtained.

(C2) In the first embodiment, when the transmission/reception results of the LF signal transmission and the RF signal reception are the results of the above (i) and (ii) indicating that the portable device 200 does not exist in the external space, Although the power slide door control device 300 is instructed to stop the closing operation, the present disclosure is not limited to this. For example, the power slide door control device 300 may be instructed to stop the closing operation only when the result (i) is obtained. In such a configuration, steps S135, S140 and S145 may be omitted. Further, for example, when the result of the following (V) is obtained, the power slide door control device 300 may be instructed to stop the closing operation.
(V) With respect to the transmission of the LF signal from any one of the three in-vehicle LF antennas 23 to 25, the RF signal is received within a predetermined period.
In such a configuration, step S120 may be omitted.

(C3) In the second embodiment, when the transmission/reception result of the LF signal transmission and the RF signal reception is the result of the above (iii) and (iV) indicating that the portable device 200 does not exist in the external space, Although the power slide door control device 300 is instructed to stop the closing operation, the present disclosure is not limited to this. For example, the power slide door control device 300 may be instructed to stop the closing operation only when the result (iii) is obtained. In such a configuration, steps S160 and S175 may be omitted. Further, for example, the power slide door control device 300 may be instructed to stop the closing operation only when the result (iV) is obtained. In such a configuration, steps S120a and S170 may be omitted.

(C4) In the closing operation control process of each embodiment, the LF signal is transmitted from the vehicle exterior LF antenna (for example, the first vehicle exterior LF antenna 21) on the same side as the operation target door and all the vehicle interior LF antennas 23 to 25. However, the present disclosure is not limited to this. In addition to these LF antennas, the LF signal may be transmitted from the vehicle exterior LF antenna (for example, the second vehicle exterior LF antenna 22) on the side opposite to the operation target door. In such a configuration, all the exterior LF antennas 21 and 22 and all the interior LF antennas 23 to 25 correspond to a subordinate concept of the specific LF antenna in the present disclosure. In addition, for example, the LF signal is transmitted from the vehicle exterior LF antenna (for example, the first vehicle exterior LF antenna 21) on the same side as the operation target door and a portion of the vehicle interior LF antennas 23 to 25. Good. In such a configuration, the vehicle exterior LF antenna on the same side as the operation target door (for example, the first vehicle exterior LF antenna 21) and a part of the vehicle interior LF antenna that transmits the LF signal are subordinate concepts of the specific LF antenna in the present disclosure. Equivalent to.

(C5) In each of the embodiments, the control device 10 includes the electronic key system control unit 115, but the control device 10 may not include the electronic key system control unit 115. In such a configuration, the electronic key system control unit 115 may be realized by another control device (for example, ECU) different from the control device 10. In such a configuration, the other control device that realizes the electronic key system control unit 115 corresponds to a subordinate concept of the vehicle-mounted device in the present disclosure.

(C6) The configuration of the electronic key system 500 in each embodiment is merely an example, and can be variously modified. For example, the two out-of-vehicle LF antennas 21 and 22 may be arranged at a place other than the outer handle portion, such as the inner handle portion of the left rear door 151 or the right rear door 152 or the inside of the door panel. Further, the number of LF antennas outside the vehicle may be any number. Similarly, the number of in-vehicle LF antennas may be any number. Further, the closing operation instruction signal transmitted from the operation unit 310 has been transmitted to the control device 10 via the power slide door control device 300, but may be directly transmitted from the operation unit 310 to the control device 10. In such a configuration, the operation unit 310 and the control device 10 may be electrically connected by a dedicated line.

(C7) In each of the embodiments, part of the configuration realized by hardware may be replaced with software. Conversely, part of the configuration realized by software may be replaced with hardware. Good. For example, at least one functional unit of the RF reception control unit 111, the LF transmission control unit 112, the instruction signal reception unit 113, the closing operation control unit 114, and the electronic key system control unit 115 is provided as an integrated circuit, a discrete circuit, or You may implement|achieve by the module which combined those circuits. Further, when part or all of the functions of the present disclosure are realized by software, the software (computer program) can be provided in a form stored in a computer-readable recording medium. The "computer-readable recording medium" is not limited to a portable recording medium such as a flexible disk or a CD-ROM, but is fixed to an internal storage device such as various RAMs and ROMs in the computer or a computer such as a hard disk. It also includes an external storage device. That is, the "computer-readable recording medium" has a broad meaning including any recording medium on which a data packet can be fixed not temporarily.

The present disclosure is not limited to the above-described embodiments and modified examples, and can be realized with various configurations without departing from the spirit thereof. For example, in order to solve some or all of the above-mentioned problems, the present embodiment corresponding to the technical features in each mode described in the section of the summary of the invention, the technical features in the modification, or the above In order to achieve a part or all of the effect of (1), it is possible to appropriately replace or combine.
