Japanese Patent No. 5102192 JP, 2006-56504, A JP 2016-22922 A JP 2003-312391 A

  In the vehicle control system, if polling of the LF signal is constantly performed by the vehicle control device in order to search for a portable device, the power consumption increases and the power of the battery that is the power source of the vehicle decreases in a short period. The vehicle control device first polls the BLE signal, which consumes less power than the LF signal, establishes communication with the second portable device, and then polls the LF signal to establish the first portable device. When the user does not carry the second portable device, the LF signal is not polled and the first portable device is not searched. For this reason, a vehicle control apparatus cannot authenticate a 1st portable machine, reservation control of a vehicle is not performed, and a user's convenience will be impaired.

  The subject of this invention is ensuring the convenience of a user in a vehicle control system, and reducing the power consumption of a vehicle control apparatus.

  A vehicle control system according to the present invention includes a vehicle control device mounted on a vehicle and a first portable device that is carried by a vehicle user and wirelessly communicates a first signal with the vehicle control device. The vehicle control device performs reservation control of the vehicle when mutual communication with the first portable device is established and the authentication of the first portable device is successful. In this configuration, there is further provided a second portable device that is carried by the user of the vehicle and wirelessly communicates with the vehicle control device the second signal that has a smaller power consumption at the time of transmission than the first signal and has a long reach. The vehicle control device includes a first search unit that searches for the first portable device by polling the first signal, and a second search unit that searches for the second portable device by polling the second signal, When searching for the first portable device by the first search unit and searching for the second portable device by the second search unit, the first signal is sent to the first transmission form before the mutual communication with the second portable device is established. And after establishing the mutual communication with the second portable device, the first signal is polled in the second transmission form. The 1st transmission form is a transmission form with a small search rate of the 1st portable machine compared with the 2nd transmission form.

  The vehicle control device according to the present invention is a vehicle control device mounted on a vehicle, and includes a first in-vehicle communication unit that wirelessly communicates a first signal to a first portable device carried by a user of the vehicle. If the communication with the first portable device is established and the authentication of the first portable device is successful, the reservation control of the vehicle is executed. Furthermore, the vehicle control device includes a second in-vehicle communication unit that wirelessly communicates a second signal that has a lower power consumption and a longer reach than the first signal with respect to the second portable device carried by the user, A first search unit that searches for the first portable device by polling the first signal by one in-vehicle communication unit, and a second search that searches for the second portable device by polling the second signal by the second in-vehicle communication unit The first search unit searches for the first portable device and the second search unit searches for the second portable device. Before the mutual communication with the second portable device is established, The signal is polled in the first transmission form, and after the establishment of mutual communication with the second portable device, the first signal is polled in the second transmission form. The 1st transmission form is a transmission form with a small search rate of the 1st portable machine compared with the 2nd transmission form.

  According to the above, the vehicle control device searches for the first portable device by polling the first signal and searching for the second portable device by polling the second signal that consumes less power and has a longer reach than the first signal. And simultaneously. For this reason, even if the user approaching the vehicle does not carry the second portable device, if the first portable device is carried, the vehicle control device establishes mutual communication with the first portable device, If the authentication of the first portable device is successful, the reservation control of the vehicle can be executed. The vehicle control device polls the first signal in the second transmission form after the mutual communication with the second portable device is established, whereas the vehicle control apparatus performs the second transmission before the mutual communication with the second portable device is established. The first signal is polled in the first transmission form in which the search rate of the first portable device is smaller than the form. For this reason, the power consumption of a 1st vehicle-mounted transmission part and a 1st search part can be restrained small before establishment of mutual communication with a vehicle control apparatus and a 2nd portable device. Therefore, it is possible to ensure the convenience for the user and reduce the power consumption of the vehicle control device.

  In the present invention, the first transmission form may be a transmission form in which the number of transmissions of the first signal per unit time or the transmission strength of the first signal is reduced as compared with the second transmission form.

  In the present invention, the vehicle control device polls the first signal in the first cycle as the first transmission form before establishing the mutual communication with the second portable device, and establishes the mutual communication with the second portable device. Thereafter, the first signal may be polled in a second period shorter than the first period as the second transmission form.

  In the present invention, the vehicle control device further includes a condition determining unit that determines whether or not a predetermined promotion condition for promoting the search for the first portable device is satisfied, and the first portable device is configured by the first search unit. And when the second search unit searches for the second portable device, the first communication is established before the communication condition with the second portable device is established and the condition determination unit determines that the promotion condition is satisfied. After the signal is polled in the first transmission form and the mutual communication with the second portable device is established and the condition determination unit determines that the promotion condition is established, the first signal is polled in the second transmission form. Also good. The promotion condition includes that a state in which it is determined that the second portable device approaches the vehicle is detected, or that a change from the first transmission form to the second transmission form is permitted. You may go out.

  In the present invention, the condition determination unit further determines whether or not a predetermined suppression condition for suppressing the search for the first portable device is satisfied, and the vehicle control device polls the first signal in the second transmission form. When it is determined that the suppression condition is satisfied by the condition determination unit, the first signal may be polled in the first transmission form. The suppression condition is that a state in which it is determined that the second portable device is moving away from the vehicle is detected, a state in which it is determined that there is no first portable device is detected, or that the first portable device is It may include that authentication was successful.

  Further, in the present invention, the contents of the reservation control for the vehicle may be input by an operation of the second portable device and set in the vehicle control device by wireless communication between the second portable device and the vehicle control device.

At this time, if mutual communication with the smartphone 30 has not been established (step S42 in FIG. 5: NO), the control unit 11 sets a state counter provided in the internal memory to “1” (step in FIG. 5). S43). On the other hand, if mutual communication with the smartphone 30 has been established (step S42 in FIG. 5: YES), the control unit 11 sets the state counter to “3” (step S44 in FIG. 5).

  FIG. 6 is a flowchart showing an LF transmission operation executed by the vehicle control device 10 in the polling process of the LF request signal in step S11a of FIG.

  When the state counter is set to “1” in step S43 in FIG. 5 (step S51 in FIG. 6: YES), the first search unit 11a of the vehicle control device 10 starts a long cycle timer (step in FIG. 6). S52). The long cycle timer measures a predetermined first time and is provided in the internal memory of the control unit 11. Further, the control unit 11 sets the state counter to “2” (step S53 in FIG. 6).

  When the state counter becomes “2” (step S54 in FIG. 6: YES), the first search unit 11a refers to the long cycle timer. When the long cycle timer times out (step S55 in FIG. 6: YES), the first search unit 11a transmits an LF request signal to the electronic key 20 by the LF transmission unit 13 (step S56 in FIG. 6). Thereafter, the long cycle timer is reset (step S57 in FIG. 6). Further, the control unit 11 sets the state counter to “1” (step S58 in FIG. 6).

  On the other hand, when the state counter is set to “3” in step S44 in FIG. 5 (step S59 in FIG. 6: YES), the first search unit 11a starts a short cycle timer (step S60 in FIG. 6). The short cycle timer measures a predetermined second time shorter than the first time described above, and is provided in the internal memory of the control unit 11. Further, the control unit 11 sets the state counter to “4” (step S61 in FIG. 6).

  When the state counter becomes “4” (step S62 in FIG. 6: YES), the first search unit 11a refers to the short cycle timer. When the short cycle timer times out (step S63 in FIG. 6: YES), the first search unit 11a transmits an LF request signal to the electronic key 20 by the LF transmission unit 13 (step S64 in FIG. 6). Thereafter, the short cycle timer is reset (step S65 in FIG. 6). Further, the control unit 11 sets the state counter to “3” (step S66 in FIG. 6).

  According to the operations of FIGS. 4 to 6, before the establishment of mutual communication between the vehicle control device 10 and the smartphone 30 (before t4 of FIG. 7), the steps S51 to S58 of FIG. An LF request signal is polled from the apparatus 10 at a predetermined long cycle (long cycle polling in FIG. 7A). This long period polling of the LF request signal is an example of the “first transmission form” of the present invention.

  Further, after the mutual communication between the vehicle control device 10 and the smartphone 30 is established (after t4 in FIG. 7), Steps S59 to S66 in FIG. 6 are repeatedly executed, and an LF request signal is predetermined from the vehicle control device 10. Is polled in a short cycle (short cycle polling in FIG. 7A). This short period polling of the LF request signal is an example of the “second transmission form” of the present invention.

  Since the number of transmissions per unit time of the LF request signal is reduced when the LF request signal is polled with a long period rather than the LF request signal is polled with a short period from the vehicle control device 10, the search rate of the electronic key 20 is increased. The power consumption of the LF transmission unit 13 and the first search unit 11a is reduced. The search rate in this case is the frequency with which the electronic key 20 is searched for by the LF request signal, for example, the number of transmissions of the LF request signal per unit time.

  According to the vehicle control system 101 of the first embodiment described above, the vehicle control device 10 searches for the electronic key 20 by polling the LF request signal, and the power consumption at the time of transmission is smaller than the LF request signal, and the reach distance is long. The search for the smartphone 30 by polling the request signal is simultaneously performed. For this reason, even if the user who has approached the vehicle 1 does not carry the smart phone 30, if the electronic key 20 is carried, the vehicle control device 10 establishes mutual communication with the electronic key 20, and the electronic key If the authentication of 20 is successful, reservation control of the vehicle 1 can be executed.

  The vehicle control device 10 polls the LF request signal in a short cycle after the mutual communication with the smartphone 30 is established, whereas the LF request signal is transmitted in a long cycle before the mutual communication with the smartphone 30 is established. Poll. For this reason, before the mutual communication with the vehicle control device 10 and the smartphone 30 is established, the power consumption of the LF transmission unit 13 and the first search unit 11a can be reduced. Thus, the vehicle control system 101 can ensure the convenience for the user and reduce the power consumption of the vehicle control device 10.

  In addition, the vehicle control device 10 polls the LF request signal in a short cycle after the mutual communication with the smartphone 30 is established, so that the search rate of the electronic key 20 approaching the vehicle 1 with the user and the smartphone 30 can be obtained. Can be increased. Then, the vehicle control device 10 establishes mutual communication with the electronic key 20, authenticates the electronic key 20, or shortens the time until execution of reservation control of the vehicle 1 after the authentication, Convenience can be improved.

  Furthermore, in 1st Embodiment, the content of the reservation control of the vehicle 1 is input by predetermined operation of the display operation part 33 of the smart phone 30, and is set to the vehicle control apparatus 10 by BLE communication between the smart phone 30 and the vehicle control apparatus 10. Is done. For this reason, the user can set the reservation control in the vehicle control device 10 by inputting the contents of the desired reservation control with the smartphone 30, and can execute the reservation control when the user gets on the vehicle.

  Next, the vehicle control system 102 of 2nd Embodiment is demonstrated, referring FIGS. 8-11. The configuration and operation of the vehicle control system 102 according to the second embodiment are the same as the configuration and operation of the vehicle control system 101 according to the first embodiment except for the points described below.

  FIG. 8 is a configuration diagram of the vehicle control system 102. In the vehicle control system 102, a condition determination unit 11 c is provided in the control unit 11 of the vehicle control device 10 in addition to the first search unit 11 a and the second search unit 11 b. Further, the BLE transceiver 15 is provided with an RSSI detector 15a. Furthermore, an acceleration sensor 37 is provided on the smartphone 30.

  The acceleration sensor 37 detects the acceleration of the smartphone 30. The control unit 31 of the smartphone 30 includes the acceleration of the smartphone 30 detected by the acceleration sensor 37 in the BLE signal and transmits the acceleration to the vehicle control device 10 by the BLE transmission / reception unit 35. For example, after the communication between the vehicle control device 10 and the smartphone 30 is established, a command for requesting the acceleration of the smartphone 30 is included in the BLE request signal, transmitted from the vehicle control device 10, and the smartphone 30 that has received the BLE request signal. In response to the above command, the acceleration detected by the acceleration sensor 37 may be included in the BLE answer signal and returned to the vehicle control device 10.

  The RSSI detection unit 15a of the vehicle control device 10 detects the RSSI value (reception intensity value) of the BLE signal when the BLE signal transmitted from the smartphone 30 is received by the BLE transmission / reception unit 15.

  FIG. 9 is a diagram showing the relationship between the reception distance of the BLE signal of the vehicle control system 102 and the RSSI value. As shown in FIG. 9, the RSSI value of the BLE signal decreases as the distance (reception distance) from the transmission source of the BLE signal increases. In other words, the RSSI value of the BLE signal increases as the distance from the transmission source of the BLE signal decreases.

  For this reason, the RSSI detection part 15a when the BLE signal transmitted from the BLE transmission / reception part 35 (FIG. 8) of the smart phone 30 is received by the BLE transmission / reception part 15 of the vehicle control apparatus 10 so that the smart phone 30 approaches the vehicle 1. The RSSI value of the BLE signal detected by (1) increases.

  The condition determination unit 11c determines whether or not a predetermined promotion condition for promoting the search for the electronic key 20 is satisfied. When the user gets on the vehicle 1 or the like, it is assumed that the user approaches the vehicle 1 while carrying the smartphone 30 and the electronic key 20. In this case, since it is better to promote the search for the electronic key 20, it is detected that a state in which the smartphone 30 is approaching the vehicle 1 (hereinafter referred to as “smartphone approach state”) is detected. It may be included in the promotion conditions.

  As the smartphone approaching state, for example, the RSSI value when the vehicle control device 10 receives the BLE signal is equal to or greater than a threshold value, and a predetermined time has elapsed since the mutual communication between the vehicle control device 10 and the smartphone 30 has been established. Or the acceleration of the smartphone 30 is greater than or equal to a predetermined value. When the user approaches the vehicle 1 while carrying the smartphone 30, the smartphone approaching state as described above is detected by the control unit 11 of the vehicle control device 10. Based on the detection result of the control unit 11, the condition determination unit 11c determines that the promotion condition is satisfied.

  In addition, for example, the permission to change the LF request signal from the long period polling to the short period polling after the mutual communication between the vehicle control apparatus 10 and the smartphone 30 is stored in the storage unit 12 of the vehicle control apparatus 10. May be included in the promotion conditions. Furthermore, at least one or two or more of the change permission, the detection of the smartphone approaching state, and other matters described above may be included in the promotion condition.

  The condition determination unit 11c also determines whether or not a predetermined suppression condition that suppresses the search for the electronic key 20 is satisfied. It is assumed that the user who does not get on the vehicle 1 goes away from the vehicle 1 while carrying the smartphone 30 and the electronic key 20. In this case, since the search for the electronic key 20 may be suppressed, it is suppressed that a state in which the smartphone 30 is determined to move away from the vehicle 1 (hereinafter referred to as “smartphone away state”) is suppressed. It may be included in the conditions.

  As the smartphone away state, for example, the RSSI value when the vehicle control device 10 receives the BLE signal is less than a threshold value, or the mutual communication between the vehicle control device 10 and the smartphone 30 is disconnected. When the user goes away from the vehicle 1 while carrying the smartphone 30, the smartphone away state as described above is detected by the control unit 11 of the vehicle control device 10. Then, based on the detection result of the control unit 11, the condition determination unit 11c determines that the suppression condition is satisfied.

  In addition, it is assumed that the user is carrying the smartphone 30 when getting on the vehicle 1 but is approaching the vehicle 1 without carrying the electronic key 20 corresponding to the vehicle control device 10. Is done. In this case, since the search for the electronic key 20 may be suppressed, it may be included in the suppression condition that an electronic key absence state in which it is determined that there is no corresponding electronic key 20 is detected.

  The electronic key absence state is, for example, predetermined in a state where mutual communication between the vehicle control device 10 and the smartphone 30 is established and mutual communication with the electronic key 20 is not established, or in a state where the authentication of the electronic key 20 is not successful. For example, time has passed. When the user carries the smartphone 30 but does not carry the corresponding electronic key 20 and approaches the vehicle 1, the absence of the electronic key as described above is caused by the control unit of the vehicle control device 10. 11 is detected. Then, based on the detection result of the control unit 11, the condition determination unit 11c determines that the suppression condition is satisfied.

  Further, for example, after the vehicle control device 10 succeeds in the authentication of the electronic key 20, the search for the electronic key 20 may be suppressed. Therefore, it may be included in the suppression condition that the authentication of the electronic key 20 is successful. Good. Furthermore, at least one or more of the authentication success, the above-described detection of the smartphone away state, the detection of the absence of the electronic key, and other matters may be included in the suppression condition.

  FIG. 10 is a diagram showing the RSSI threshold setting position P of the BLE signal in the vehicle control system 102. The threshold of the RSSI value of the BLE signal used for detecting the above-mentioned smartphone approaching state or smartphone away state is, for example, the vehicle control of the BLE signal transmitted from the smartphone 30 at the RSSI threshold setting position P indicated by the broken line in FIG. It is set to be equal to the detection value by the RSSI detection unit 15a when received by the BLE transmission / reception unit 15 of the apparatus 10 (FIG. 9 also shows the RSSI threshold setting position P and the RSSI threshold of the BLE signal). The RSSI threshold setting position P is outside the LF communication area A1 between the vehicle control device 10 and the electronic key 20 and inside the BLE communication area A2 between the vehicle control device 10 and the smartphone 30.

  For this reason, when the smartphone 30 is inside the BLE communication area A2 and outside the RSSI threshold setting position P, when the BLE signal from the smartphone 30 is received by the BLE transmission / reception unit 15, it is detected by the RSSI detection unit 15a. The RSSI value is less than the threshold value. Further, when the smartphone 30 approaches the vehicle 1 inside the RSSI threshold setting position P, the RSSI value detected by the RSSI detection unit 15a when the BLE signal from the smartphone 30 is received by the BLE transmission / reception unit 15 is the threshold value. That's it.

  FIG. 11 is a flowchart showing the state setting operation of the vehicle control device 10 of the vehicle control system 102. When the communication state between the vehicle control device 10 and the smartphone 30 changes (step S41 in FIG. 11: YES) and the mutual communication between the vehicle control device 10 and the smartphone 30 is established (step S42 in FIG. 11: YES), the condition The determination unit 11c confirms whether the promotion condition is satisfied. At this time, if the promotion condition is not satisfied (step S45 in FIG. 11: NO), the control unit 11 sets the state counter to “1” (step S43 in FIG. 11). On the other hand, if the promotion condition is satisfied (step S45 in FIG. 11: YES), the control unit 11 sets the state counter to “3” (step S44 in FIG. 11).

  On the other hand, when the communication state between the vehicle control device 10 and the smartphone 30 has not changed (step S41 in FIG. 11: NO), the control unit 11 determines whether the value of the state counter is “3” or “4”. Confirm whether or not. At this time, if the LF request signal is polled in a short cycle, the condition counter 11c suppresses because the state counter is set to “3” or “4” (step S46: YES in FIG. 11). It is determined whether the condition is satisfied. If the suppression condition is satisfied (step S47 in FIG. 11: YES), the control unit 11 sets the state counter to “1” (step S43 in FIG. 11). As a result, the LF request signal is polled at a long period in steps S51 to S58 in FIG.

  According to the second embodiment described above, in the vehicle control device 10, when the electronic key 20 is searched for by the first searching unit 11a and the smart phone 30 is searched for by the second searching unit 11b, mutual communication with the smart phone 30 is performed. The LF request signal is polled at a long period before communication is established and the promotion condition for promoting the search for the electronic key 20 is established. Moreover, after mutual communication with the smartphone 30 is established and the promotion condition is established, the LF request signal is polled in a short cycle. For this reason, even if the mutual communication between the vehicle control device 10 and the smartphone 30 is established by the long-period polling of the LF request signal, the long-period polling continues as long as the search for the electronic key 20 does not have to be promoted. Thus, the power consumption of the vehicle control device 10 can be reduced. And when it is better to promote the search of the electronic key 20, since the LF request signal is polled in a short cycle, the search rate of the electronic key 20 by the vehicle control device 10 can be increased. In addition, the time until the vehicle control device 10 establishes mutual communication with the electronic key 20, authenticates the electronic key 20, or executes reservation control of the vehicle 1 after the authentication is shortened. Convenience can be improved.

  Moreover, in 2nd Embodiment, the electronic key 20 approaches the vehicle 1 with the smart phone 30 by including the change permission from the long period polling of the smart phone approach state and the long period polling of the LF request signal to the short period polling in the promotion condition. If the transmission permission of the transmission cycle is not set, the long-period polling of the LF request signal can be continued and the power consumption of the vehicle control device 10 can be reduced. In addition, when the mutual communication between the vehicle control device 10 and the smartphone 30 is established, the electronic key 20 is approaching the vehicle 1 along with the smartphone 30, or the change permission of the transmission cycle is set. Furthermore, since the short-term polling of the LF request signal is started, the search rate of the electronic key 20 by the vehicle control device 10 can be increased and the convenience for the user can be improved.

  In the second embodiment, when the vehicle control apparatus 10 polls the LF request signal with a short period, if the suppression condition for suppressing the search for the electronic key 20 is satisfied, the LF request signal has a long period. Polled. That is, when the search for the electronic key 20 does not have to be promoted, the polling cycle of the LF request signal is returned from the short cycle to the long cycle, so that the power consumption of the vehicle control device 10 can be reduced.

  Furthermore, in the second embodiment, the electronic key 20 is moved away from the vehicle 1 along with the smartphone 30 by including the detection of the smartphone away state, the detection of the absence of the electronic key, and the successful authentication of the electronic key 20 in the suppression conditions. If there is no electronic key 20 corresponding to the vehicle control device 10 or if the authentication of the electronic key 20 is successful, the polling cycle of the LF request signal is returned from the short cycle to the long cycle, and the vehicle control device 10 Power consumption can be reduced.

  The present invention can employ various embodiments other than those described above. For example, in the above embodiment, before the establishment of mutual communication between the vehicle control device 10 and the smartphone 30, an example in which the polling cycle of the LF request signal is made longer than that after the establishment and the search rate of the electronic key 20 is suppressed. Although shown, the present invention is not limited to this. In addition to this, for example, before establishing the mutual communication between the vehicle control device 10 and the smartphone 30, the number of antennas that transmit the LF request signal is reduced after the establishment, and the number of transmissions per unit time of the LF request signal is reduced. By reducing, the search rate of the electronic key 20 may be suppressed. Further, before establishing the mutual communication between the vehicle control device and the smartphone, the search rate of the electronic key 20 may be suppressed by lowering the transmission strength of the LF request signal after the establishment. The search rate in this case is a rate at which the electronic key 20 is detected by the search, and is, for example, a rate of the number of receptions of the answer signal from the electronic key 20 with respect to the number of transmissions of the LF request signal.

  In other words, the first transmission form and the second transmission form of the LF request signal are respectively set to transmission forms in which the search rate of the electronic key is smaller before establishment of mutual communication between the vehicle control device and the smartphone. do it.

  Moreover, in 2nd Embodiment, although the vehicle control apparatus 10 showed the example which detects the RSSI value of the BLE signal received from the smart phone 30 for success / failure determination of a promotion condition or a suppression condition, this invention is only this. It is not limited. In addition to this, for example, the smart phone 30 detects the RSSI value of the BLE signal received from the vehicle control device 10 and notifies the vehicle control device 10, and the vehicle control device 10 promotes based on the notified RSSI value. Alternatively, the success or failure of the suppression condition may be determined.

  Moreover, in 2nd Embodiment, although the acceleration sensor 37 provided in the smart phone 30 detected the acceleration of the smart phone 30 used for success / failure determination of a promotion condition was shown, this invention is not limited only to this. . In addition to this, for example, the RSSI value of the BLE signal received by the vehicle control device 10 from the smartphone 30 may be detected at a predetermined period, and the acceleration of the smartphone 30 may be detected based on the temporal change of the RSSI value. . Moreover, you may detect the approach state and the away state of the smart phone 30 with respect to the vehicle 1 based on the time change of the said RSSI value.

  Moreover, in 2nd Embodiment, although the success or failure of the promotion condition and the suppression condition was determined in the vehicle control apparatus 10, respectively, the example which changed the transmission form of LF request signal based on this determination result was shown, but this invention is shown. It is not limited only to this. Only the success or failure of the promotion condition and the suppression condition may be determined, and the transmission form of the LF request signal may be changed based on the determination result.

  Moreover, although the example which set the content of the reservation control of the vehicle 1 by the user performing predetermined operation with the smart phone 30 was shown in the above embodiment, this invention is not limited only to this. In addition to this, for example, the reservation content may be input and set by the user performing a predetermined operation with an input / output device (not shown) provided in the vehicle 1. In addition, a user may input a reservation content by performing a predetermined operation with the electronic key 20, and the reservation content may be set in the vehicle control device 10 by wireless communication between the electronic key 20 and the vehicle control device 10. . Furthermore, the content of the reservation control may be set in the vehicle control device 10 in an initial state.

  Moreover, in the above embodiment, as shown in FIG.1 and FIG.8, although the example which provided only one control part 11 in the vehicle control apparatus 10 was given, this invention is not limited only to this.

The control unit 11x is provided with a first search unit 11a and a condition determination unit 11cx. The second ECU 10y includes a control unit 11y, a BLE transmission / reception unit 15, an in-vehicle communication unit 16y, and a storage unit 12y. The control unit 11y is provided with a second search unit 11b and a condition determination unit 11cy.

  In the first ECU 10x, the first search unit 11a searches for the electronic key 20 using the LF transmission unit 13 and the UHF reception unit 14, and the control unit 11x establishes mutual communication with the electronic key 20 based on the search result. Judge whether or not. In addition, the condition determination unit 11cx determines whether or not the electronic key 20 search is suppressed or promoted based on the search result of the electronic key 20, the presence / absence of mutual communication with the electronic key 20, or the storage content of the storage unit 12x. Whether or not is established is determined.

  In 2ECU10y, the 2nd search part 11b searches the smart phone 30 by the BLE transmission / reception part 15, and the control part 11y judges whether the mutual communication with the smart phone 30 was established based on the search result. In addition, the condition determination unit 11cy establishes the suppression condition or the promotion condition for the search for the electronic key 20 based on the search result of the smartphone 30, the presence / absence of mutual communication with the smartphone 30, or the storage content of the storage unit 12y. Determine the presence or absence.

  And control part 10x, 10y mutually communicates via the bus | bath 2 by in-vehicle communication part 16x, 16y, the search result of the electronic key 20 or the smart phone 30, a communication state with the electronic key 20 or the smart phone 30, and promotion conditions And information such as success / failure conditions are transmitted and received, and each unit is controlled based on the information.

  As another example, instead of the condition determination units 11cx and 11cy, a condition determination unit that determines both the acceleration condition and the suppression condition may be provided in any one of the ECUs 10x and 10y. Alternatively, one of the ECUs 10x and 10y may be provided with an acceleration condition determination unit that determines the acceleration condition, and the other may be provided with a suppression condition determination unit that determines the suppression condition. Alternatively, the condition determination units 11cx and 11cy may be omitted.

  Moreover, although the example which used the electronic key 20 as a 1st portable machine and used the smart phone 30 as a 2nd portable machine was shown in the above embodiment, this invention is not limited only to this. For example, an electronic key, FOB, smartphone, wearable device directly worn by the user, or other portable terminal device may be used as the first portable device or the second portable device.
