The in-vehicle control unit can determine the position of the smartphone from the signal strength of the radio signal transmitted and received when checking the smartphone.
By the way, when the transmission / reception interval of the wireless signal between the in-vehicle control unit and the smartphone becomes long, the position determination of the smartphone may not catch up with the movement of the user. In this case, since the operation of an appropriate in-vehicle device is not permitted, user convenience is poor. This problem can be solved by shortening the wireless signal transmission / reception interval. However, it is well known that verification requires high power consumption because it requires encryption and decryption of keys. In addition to the function as a vehicle key, a smartphone has a function of making a call or connecting to the Internet. Therefore, if the battery is consumed quickly by the verification, in addition to the function as the vehicle key, functions other than the function may be limited.

  In the above-mentioned in-vehicle communication system, a smartphone is used as an electronic terminal. However, even if the electronic terminal is a tablet terminal that does not have a telephone function, a portable music terminal, or a notebook personal computer, the same problem occurs. May occur.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide an in-vehicle communication system that consumes less power in an electronic terminal and is user-friendly.

  In order to solve the above-described problem, an in-vehicle communication system includes an electronic terminal communication unit that performs short-range wireless communication with an electronic terminal that uses battery power as a drive source, and a position of the electronic terminal with respect to the vehicle through the short-range wireless communication. A vehicle-mounted control unit that checks the electronic terminal and permits the vehicle-mounted device to start according to the position of the electronic terminal when the verification is established, and the vehicle-mounted control unit includes the first electronic terminal When it is determined that the electronic device is located in the range, the start of the first in-vehicle device is permitted, and when the electronic terminal is determined to be located in the second range, the second in-vehicle device is permitted to be started. The gist is to perform collation of the electronic terminal using a trigger when the position of the electronic terminal is switched between the first range and the second range.

  According to this system, the in-vehicle control unit performs collation using the movement of the electronic terminal between the first range and the second range as a trigger, and if the collation is established, Allow startup. On the other hand, even if the position determination of the electronic terminal is dense, the in-vehicle control unit does not collate the electronic terminal unless the electronic terminal is moved between the first range and the second range. For this reason, there is little power consumption in an electronic terminal. Moreover, since the position determination of an electronic terminal can be made dense, the followability with respect to the movement of an electronic terminal, ie, a user's movement, is good. For this reason, since the start of the vehicle-mounted device corresponding to the user's position is permitted, the user-friendliness is good.

  In the above-described system, the on-vehicle control unit may confirm that the position of the electronic terminal is switched from the third range in which the start of the first on-vehicle device and the second on-vehicle device is not permitted to the first range or the second range. When the electronic terminal is collated as a trigger and the first range or the second range is switched to the third range, the electronic terminal is preferably not collated.

  According to this system, the in-vehicle control unit performs collation only when the electronic terminal moves to a range where the in-vehicle device may be started, so the electronic terminal moves to a range where the electronic terminal is not likely to start the in-vehicle device. In this case, the power consumption is lower than that of the system that performs the verification.

In the above system, the electronic terminal is preferably a high function mobile phone having a telephone function and an Internet function.
According to this system, vehicle control can be performed using a high-function mobile phone.

  The in-vehicle communication system of the present invention has an effect that power consumption in an electronic terminal is small and user convenience is good.

  In addition, the memory 11a has an outdoor area when the vehicle 10 receives a radio signal transmitted from the outdoor determination area S2 that is narrower than the communication area S3 shown in FIG. 2 and covers the outer periphery of the vehicle door. The determination RSSI value is stored. Further, in the memory 11a, when the vehicle 10 receives a radio signal transmitted from the indoor determination area S1 which is set smaller than the outdoor determination area S2 shown in FIG. 2 and does not leak outside the vehicle door. The room determination RSSI value is stored. The indoor determination area S1 corresponds to the first area, and the outdoor determination area S2 corresponds to the second area.

  The in-vehicle control unit 11 has a search mode for searching for a communication partner through the BT communication unit 12, a non-search mode for not searching for a communication partner, and a BT impossible mode for not performing BT communication. The search mode and the BT impossible mode, and the searched mode and the BT impossible mode are switched by operating an input device (not shown). The search mode and the search target mode are executed each time a predetermined time set in advance elapses. The predetermined time, which is a reference for switching between the search mode and the search mode, is stored in advance in the memory 11a.

  The in-vehicle control unit 11 exchanges a BT signal with the communication partner when the search is performed by itself or when a common passkey is exchanged with the communication partner. Judge that the link has been established. In either the search mode or the searched mode, the in-vehicle control unit 11 always maintains a BT signal (BT position confirmation signal, BT signal with the communication partner with which the link is established) while the link is established. (BT collation request signal, BT position response signal, BT collation response signal).

The in-vehicle controller 11 determines that the link with the communication partner has been canceled when the BT signal cannot be received from the communication partner with which the link has been established.
The in-vehicle control unit 11 in the search mode requests a device having a pass key and in-vehicle code stored in its own memory 11a and a pass key common to itself to establish a link with itself. When the establishment of the link is permitted, a link request signal including link request information for requesting a pass key is generated. The generated link request signal is wirelessly transmitted through the BT communication unit 12.

  In the search mode and the searched mode, the in-vehicle control unit 11 receives the link request signal from another device, and determines whether or not the pass key included in the link request signal is the same as the pass key stored in the memory 11a. When determined to be common, it is determined that a link has been established with a communication partner having a code unique to the device included in the link response signal, and the passkey and vehicle code stored in the memory 11a; A link response signal including link permission information indicating that link establishment is permitted is generated. The generated link response signal is wirelessly transmitted through the BT communication unit 12.

  In the search mode, when the in-vehicle control unit 11 receives a link response signal from another device through the BT communication unit 12, it determines whether or not the pass key included in the link response signal is the same as the pass key stored in the memory 11a. To do. If it is determined that the link is common, it is determined that a link has been established with a communication partner having a code unique to the device included in the link response signal. For example, when the code unique to the device included in the link response signal is a smartphone code, it is determined that a link has been established with the smartphone control unit 21.

  When there is a communication partner with which a link has been established, the in-vehicle control unit 11 generates a BT position confirmation signal for confirming the position and a BT collation request signal including an ID code for requesting collation. . The generated BT signal is wirelessly transmitted through the BT communication unit 12.

  Moreover, the vehicle-mounted control part 11 will perform the process according to the information contained in a BT signal, if a BT signal is received from the communicating party with which the link is established. For example, when the BT signal is a BT verification response signal that is a response to the BT verification request signal, that is, when an ID code is included, ID code verification is performed. When verification of the ID code is established, the operation of the in-vehicle device corresponding to the position of the smartphone 20 is permitted. When the BT signal is a BT position response signal that is a response to the BT position confirmation signal, that is, when the ID code is not included, the position of the smartphone 20 is determined. In the position determination of the smartphone 20, when it is determined that the smartphone 20 has moved between the in-vehicle determination area S1 and the out-of-vehicle determination area S2, the smartphone 20 changes from the communication area S3 to the in-vehicle determination area S1 or the out-of-vehicle determination area S2. If it is determined that the vehicle has moved, the in-vehicle controller 11 generates a BT verification request signal. On the other hand, when it is determined that the smartphone 20 is located in the same area as the previous position determination, the in-vehicle control unit 11 generates a BT position confirmation signal again. When the RSSI value of the received BT signal is greater than or equal to the indoor determination RSSI value, the in-vehicle controller 11 determines that the communication partner is within the indoor determination area S1 and the RSSI value of the received BT signal is greater than the indoor determination RSSI value. If the outdoor determination RSSI value is low or higher, it is determined that the communication partner is located in the outdoor determination area S2.

  The in-vehicle control unit 11 permits the operation of the door lock device 17 when the smartphone 20 is located in the outdoor determination area S2 and collation is established. In this state, when it is detected that the door handle switch 16 is pushed, the vehicle-mounted control unit 11 switches between locking and unlocking the door lock through the door lock device 17.

  Moreover, the vehicle-mounted control part 11 permits the engine start control of the engine control apparatus 15, when the smart phone 20 is located in indoor determination area S1, and collation is materialized. In this state, when it is detected that the engine switch 14 has been pushed, the in-vehicle control unit 11 performs engine start control through the engine control device 15.

<Operation of in-vehicle communication system>
Next, the operation of the in-vehicle communication system 1 will be described according to the sequence chart shown in FIG.

  As shown in FIG. 3, the in-vehicle control unit 11 periodically generates a link request signal (step S1). When the user who has the smartphone 20 enters the communication area S3, the smartphone 20 can receive a link request signal.

When the smartphone control unit 21 recognizes the link request signal, the smartphone control unit 21 generates a link response signal (step S2).
The in-vehicle controller 11 recognizes that the link with the smartphone controller 21 has been established through recognition of the link response signal (step S3). Moreover, the vehicle-mounted control part 11 judges the position of the smart phone 20 with respect to the vehicle 10 from the signal strength of the link response signal to receive (step S4). And the vehicle-mounted control part 11 produces | generates a BT collation request signal (step S5).

  The smartphone control unit 21 recognizes that the link with the in-vehicle control unit 11 has been established through the recognition of the BT verification request signal (step S6). Then, a BT verification response signal is generated (step S7).

  The in-vehicle control unit 11 recognizes that the link with the smartphone control unit 21 is continued through the recognition of the BT verification response signal (step S8). Then, the ID code included in the BT verification response signal is verified (step S9). When collation is materialized, in-vehicle control part 11 permits operation of in-vehicle equipment according to the area where smart phone 20 which is the position of smart phone 20 with respect to vehicle 10 is located (Step S10). That is, the vehicle-mounted control unit 11 permits the start of the engine when the smartphone 20 is located in the area S1, and permits the start of the door lock device when the smartphone 20 is located in the area S2.

Next, the vehicle-mounted control part 11 produces | generates a BT position confirmation signal (step S11).
The smartphone control unit 21 recognizes that the link with the in-vehicle control unit 11 is continued through the recognition of the BT position confirmation signal (step S12). Then, a BT position response signal is generated (step S13).

  The in-vehicle control unit 11 recognizes that the link with the smartphone control unit 21 is continued through the recognition of the BT position response signal (step S14). Then, the position of the smartphone 20 is determined (step S15).

  The vehicle-mounted control part 11 transfers a process to step S5, when the position of the smart phone 20 judged in step S15 differs from the position of the smart phone 20 judged in step S4. On the other hand, when the area where the smartphone 20 determined in step S15 is the same as the area where the smartphone 20 determined in step S4 is the same, the process proceeds to step S10. That is, as shown in FIG. 4, the in-vehicle control unit 11 periodically generates a BT position confirmation signal while the link is established with the smartphone control unit 21, and only when the area of the smartphone 20 is switched. A verification request signal is generated.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) The in-vehicle control unit 11 performs collation of the smartphone 20 when it is determined that the smartphone 20 has moved between the indoor determination area S1 and the outdoor determination area S2, and when the collation is established, The start of the in-vehicle device (engine control device 15 and door lock device 17) according to the position is permitted. Thus, since collation is performed only when the smartphone 20 moves, power consumption in the smartphone 20 is less than that of a system that performs collation regardless of movement. Moreover, since the position judgment of the smart phone 20 can be made dense, the followability with respect to the movement of the smart phone 20, ie, a user's movement, is good. For this reason, since the start of the vehicle-mounted device corresponding to the user's position is permitted, the user-friendliness is good.

  (2) The in-vehicle control unit 11 performs collation of the smartphone 20 when it is determined that the smartphone 20 has moved from the communication area S3 to the in-vehicle determination area S1 or the out-of-vehicle determination area S2, and when the collation is established, the smartphone 20 The start of the on-vehicle equipment (engine control device 15 and door lock device 17) according to the position of the is permitted. On the other hand, when it is determined that the smartphone 20 has moved from the in-vehicle determination area S1 or the out-of-vehicle determination area S2 to the communication area S3, the in-vehicle control unit 11 does not perform verification of the smartphone 20. That is, since collation is performed only when there is a possibility that the user may start the in-vehicle device (the engine control device 15, the door lock device 17), the smartphone 20 may move to a range where there is no possibility of starting the in-vehicle device. The power consumption in the smartphone 20 is small compared to the system that performs the verification.

In addition, you may change the said embodiment as follows.
-In above-mentioned embodiment, although the engine control apparatus 15 and the door lock apparatus 17 were demonstrated as vehicle equipment, another apparatus may be sufficient. Further, the number of in-vehicle devices is not limited to two and may be three or more. In this case, an area corresponding to the number of in-vehicle devices is set, and the in-vehicle control unit 11 collates the smartphone 20 only when the smartphone 20 moves to a different area. Even if comprised in this way, the effect similar to the effect shown to (1) of the said embodiment can be acquired.

  In the above embodiment, the outdoor determination area and the indoor determination area do not overlap, but may overlap. In this overlapping region, both starting of the engine control device 15 and starting of the door lock device 17 may be permitted. In addition, you may apply this other example to the above-mentioned another example.

  In the above embodiment, the in-vehicle control unit 11 may collate the smartphone 20 when it is determined that the smartphone 20 has moved from the in-vehicle determination area S1 or the out-of-vehicle determination area S2 to the communication area S3.

In the above embodiment, switching between the search mode and the non-search mode is not limited to time.
In the above embodiment, the in-vehicle control unit 11 establishes a link with the communication partner if the pass key of the received link request signal is common with the own pass key in the search mode and the non-search mode. In addition to this, the link establishment may be determined after confirming the code unique to the device. For example, if the in-vehicle control unit 11 is a link request signal from the smartphone control unit 21 that has canceled the link from itself through a code (in this case, a smartphone code) unique to the device included in the link request signal, A link is not established with the control unit 21. When comprised in this way, the smart phone control part 21 can establish a link between the apparatuses which have another BT communication part. The same applies when the in-vehicle control unit 11 is replaced with the smartphone control unit 21.

  In the above embodiment, the communication partner of the in-vehicle control unit 11 is not limited to the smartphone 20. For example, various electronic terminals such as a terminal having no telephone function and a terminal having a reproduction and recording function may be used.

  In the above embodiment, the communication between the vehicle 10 and the smartphone 20 is the wireless communication of the BLUETOOTH standard, but the communication standard is not limited to this. For example, near field communication called NFC may be used.
