[Processing of vehicle control system 101]
Next, processing of the vehicle control system 101 will be described with reference to FIGS.

(Communication control processing)
First, the communication control process executed by the vehicle control system 101 will be described with reference to the flowchart of FIG. In this process, for example, the portable terminal 114 is placed within a chargeable range of the charging pad 125, and the device detection unit 253 of the charging pad 125 detects that the portable terminal 114 is installed on the charging pad 125. This is started when the detection result is notified to the control unit 201 of the ECU 121.

  In step S <b> 1, the in-vehicle system 111 starts charging control of the mobile terminal 114. Specifically, the charging control unit 212 of the ECU 121 controls the charging unit 252 of the charging pad 125 to start supplying charging power to the mobile terminal 114. Thereby, charging of the battery 358 of the portable terminal 114 is started.

  In step S <b> 2, the communication control unit 211 of the ECU 121 determines whether communication between the mobile terminal 114 and the charging pad 125 is possible. Specifically, the NFC communication unit 251 of the charging pad 125 attempts to establish NFC communication with the mobile terminal 114 under the control of the communication control unit 211. If the NFC communication with the mobile terminal 114 is normally established, the communication control unit 211 determines that communication between the mobile terminal 114 and the charging pad 125 is possible, and the process proceeds to step S3.

  In step S3, the ECU 121 executes wireless communication switching processing 1. Here, the details of the wireless communication switching process 1 will be described with reference to the flowchart of FIG.

  In step S <b> 31, the ECU 121 stops wireless communication between the portable device 113 and the ECU 121. Specifically, the wireless communication unit 202 of the ECU 121 transmits a signal indicating an instruction to stop wireless communication to the portable device 113 via the antenna 122 or the antenna 124 under the control of the communication control unit 211.

  The communication control unit 311 of the portable device 113 receives a signal from the ECU 121 via the wireless communication unit 305. Then, when transmitting a signal from the portable device 113, the communication control unit 311 controls to transmit from the BLE communication unit 306 instead of the wireless communication unit 305.

  Further, the communication control unit 211 of the ECU 121 stops the operation of the wireless communication unit 202. At this time, transmission of the signal from the portable device 113 by wireless communication is stopped, and the signal is not received from the portable device 113. Therefore, without stopping a part or all of the reception function of the wireless communication unit 202. Only the transmission function may be stopped.

  In step S <b> 32, the ECU 121 starts communication between the portable device 113 and the ECU 121 via the charging pad 125 and the portable terminal 114. Specifically, the communication control unit 211 of the ECU 121 sends a signal indicating a command to execute communication relay between the portable device 113 and the charging pad 125 to the portable terminal 114 via the NFC communication unit 251 of the charging pad 125. Send.

  The communication control unit 361 of the portable terminal 114 receives a signal from the ECU 121 via the NFC communication unit 356. Thereafter, the communication control unit 361 transmits a signal received from the charging pad 125 via the NFC communication unit 356 to the portable device 113 via the BLE communication unit 355 and transmits the signal to the portable device 113 via the BLE communication unit 355. Is controlled to be transmitted to the charging pad 125 via the NFC communication unit 356.

  As a result, communication between the portable device 113 and the ECU 121 is performed via the portable terminal 114 and the charging pad 125 instead of the normal direct wireless communication.

  In step S <b> 33, the ECU 121 changes the position detection method of the portable device 113 to a method based on the communication state between the portable device 113 and the portable terminal 114. Specifically, when detecting the position of the portable device 113, the position detection unit 213 of the ECU 121 determines the reception intensity of the signal from the portable device 113 via the communication control unit 211 and the NFC communication unit 251 of the charging pad 125. A signal indicating a measurement result transmission command is transmitted to portable terminal 114.

  The communication control unit 361 of the portable terminal 114 receives a signal from the ECU 121 via the NFC communication unit 356. Then, the communication control unit 361 acquires a measurement result of the reception intensity of the signal from the portable device 113 from the BLE communication unit 355, and transmits a signal indicating the measurement result to the charging pad 125 via the NFC communication unit 356.

  The NFC communication unit 251 of the charging pad 125 supplies the signal received from the portable terminal 114 to the position detection unit 213 via the communication control unit 211 of the ECU 121. The position detection unit 213 calculates the distance between the portable device 113 and the portable terminal 114 based on the measurement result of the reception intensity by the portable terminal 114. Note that this distance calculation can also be performed by the portable terminal 114.

  Here, the portable terminal 114 is installed on the charging pad 125, and its position is fixed. Therefore, the position detection unit 213 detects an area where the portable device 113 exists based on the calculated distance and determines the inside / outside determination of the portable device 113 based on the position of the portable terminal 114 (position of the charging pad 125). Can be done. And the position detection part 213 notifies the result of the position detection of the portable device 113 to each part of the vehicle-mounted system 111 or each part of the vehicle 102 as needed.

  Thereafter, the wireless communication switching process 1 ends.

  Returning to FIG. 5, in step S <b> 4, the device detection unit 253 of the charging pad 125 determines whether or not the mobile terminal 114 is detached from the charging pad 125. This process is periodically repeated until it is determined that the mobile terminal 114 has been detached from the charging pad 125. When the portable terminal 113 does not exist within the chargeable range of the charging pad 122, that is, when the portable terminal 113 goes out of the chargeable range of the charging pad 122, the device detection unit 253 It is determined that 114 is detached from the charging pad 125, and the process proceeds to step S5.

  In step S5, the ECU 121 executes the wireless communication switching process 2, and the communication control process ends. Here, the details of the wireless communication switching process 2 will be described with reference to the flowchart of FIG.

  In step S <b> 61, the ECU 121 starts wireless communication between the portable device 113 and the ECU 121. Specifically, the communication control unit 211 of the ECU 121 starts the operation of the wireless communication unit 202. In addition, the wireless communication unit 202 transmits a signal indicating an instruction to start wireless communication to the portable device 113 via the antenna 122 or the antenna 124 under the control of the communication control unit 211.

  The communication control unit 311 of the portable device 113 receives a signal from the ECU 121 via the wireless communication unit 305. Then, when transmitting a signal from the portable device 113, the communication control unit 311 controls to transmit from the wireless communication unit 305 instead of from the BLE communication unit 306.

  Thereby, the wireless communication between the portable device 113 and the ECU 121 is resumed.

  In step S <b> 62, the communication control unit 211 of the ECU 121 stops communication between the portable device 113 and the ECU 121 via the charging pad 125 and the portable terminal 114.

  In step S <b> 63, the ECU 121 changes the position detection method of the portable device 113 to a method based on the state of wireless communication with the portable device 113. That is, when detecting the position of the portable device 113, the position detection unit 213 of the ECU 121 detects the position of the portable device 113, for example, by detecting which antenna 122 the portable device 113 has received a signal from. . And the position detection part 213 notifies the result of the position detection of the portable device 113 to each part of the vehicle-mounted system 111 or each part of the vehicle 102 as needed.

  Thereafter, the wireless communication switching process 2 ends.

  Returning to FIG. 5, if it is determined in step S <b> 2 that communication between the portable terminal 114 and the charging pad 125 is impossible, the communication method between the portable device 113 and the ECU 121 is not changed. Then, the communication control process ends.

  As described above, the communication method between the portable device 113 and the ECU 121 can be switched simply by installing the portable terminal 114 on the charging pad 125 or removing it from the charging pad 125.

  Further, wireless communication between the ECU 121 and the portable device 113 via the plurality of antennas 122 consumes more power than NFC communication between the charging pad 125 and the portable terminal 114. Therefore, the power consumption of the in-vehicle system 111 can be reduced while the portable terminal 114 is installed on the charging pad 125.

  Further, wireless communication between the ECU 121 and the portable device 113 via the plurality of antennas 122 consumes more power than BLE communication between the portable device 113 and the portable terminal 114. For example, in the former case, when the position of the portable device 113 is detected, the portable device 113 needs to respond to signals from the plurality of antennas 122, and the number of communications increases. On the other hand, in the latter case, when the position of the portable device 113 is detected, the portable device 113 needs to perform BLE communication with the portable terminal 114 only once. Accordingly, the power consumption of the portable device 113 can be reduced while the portable terminal 114 is installed on the charging pad 125.

  Next, processing for detecting theft of the portable terminal 114 in the vehicle 102 will be described with reference to FIGS.

(First embodiment of theft detection processing by the portable terminal 114)
First, a first embodiment of processing when the portable terminal 114 detects theft of the portable terminal 114 will be described with reference to a flowchart of FIG. This process is started, for example, when the mobile terminal 114 is installed on the charging pad 125, in other words, when the mobile terminal 114 is placed within a chargeable range of the charging pad 125.

  In step S <b> 101, the state detection unit 363 determines whether or not the mobile terminal 114 is detached from the charging pad 125. This determination process is periodically repeated until, for example, it is determined that the mobile terminal 114 is detached from the charging pad 125. When the mobile terminal 113 is not within the chargeable range of the charging pad 122, that is, when the mobile terminal 113 goes out of the chargeable range of the charging pad 122, the state detection unit 363 It is determined that 114 is disconnected from the charging pad 125, and the process proceeds to step S102.

  In step S <b> 102, the mobile terminal 114 detects the position of the mobile device 113. Specifically, the BLE communication unit 355 attempts BLE communication with the portable device 113 under the control of the communication control unit 361. When the communication with the portable device 113 is successful, the BLE communication unit 355 measures the reception intensity of the signal from the portable device 113 and supplies the measurement result to the position detection unit 364 via the communication control unit 361. The position detection unit 364 calculates the distance to the portable device 113 based on the reception intensity of the signal from the portable device 113. Thereby, a range where the portable device 113 exists is detected with reference to the current position of the portable terminal 114, that is, the vicinity of the charging pad 125.

  In step S103, the communication control unit 361 determines whether communication with the portable device 113 is possible based on the result of the process in step S102. If it is determined that communication with the portable device 113 is possible, the process proceeds to step S104.

  In step S104, the position detection unit 364 determines whether or not the portable device 113 is within a predetermined range based on the result of the process in step S102. If it is determined that the portable device 113 does not exist within the predetermined range, the process proceeds to step S105.

  In step S105, the portable terminal 114 notifies the portable device 113, and the theft detection process ends.

  For example, when the predetermined range used for the determination process in step S104 is set to be approximately the same as the interior of the vehicle 102, the current situation is that the portable device 113 is outside the vehicle and the portable terminal 114 is connected to the charging pad 125. The situation is out of place. This is because, for example, a user (for example, the owner of the vehicle 102) who has the portable device 113 leaves the portable terminal 114 in the vehicle while charging the portable terminal 114 and goes out of the vehicle. Is assumed to be detached from the charging pad 125. Therefore, a third party who does not have the portable device 113 may enter the vehicle and the portable terminal 114 may be stolen.

  Therefore, the mobile terminal 114 notifies the mobile device 113 that the mobile terminal 114 may be stolen. Specifically, under the control of the communication control unit 361, the BLE communication unit 355 provides a predetermined signal (hereinafter referred to as a theft notification signal A) for notifying that the portable terminal 114 may be stolen. , Transmitted to the portable device 113 by BLE communication.

  The communication control unit 311 of the portable device 113 receives the theft notification signal A from the portable terminal 114 via the BLE communication unit 306. For example, the display unit 304 displays a screen for notifying that the mobile terminal 114 in the vehicle 102 may be stolen under the control of the display control unit 313.

  Thereby, the user who possesses the portable device 113 can quickly detect the possibility of the theft of the portable terminal 114 in the vehicle, and can respond quickly. As a result, the portable terminal 114 can be prevented from being stolen. Moreover, when there is a possibility of theft of the portable terminal 114 in the vehicle, there is a high possibility that a third party has entered the vehicle. Therefore, the user who possesses the portable device 113 can quickly detect that there is a possibility that a third party indirectly enters the vehicle and the vehicle 102 is stolen by this notification, and responds promptly. be able to.

  In addition, you may make it notify the possibility of theft of the portable terminal 114 by methods other than a display. For example, the notification may be performed by a method such as sound by a buzzer, lighting or blinking of light by an LED, vibration of the portable device 113 by vibration, or the like. Further, notification may be performed by combining a plurality of methods.

  On the other hand, if it is determined in step S104 that the portable device 113 is within the predetermined range, the process of step S105 is skipped, and the theft detection process ends. That is, the portable device 113 exists in the predetermined range when, for example, the user who owns the portable device 113 is in the vehicle, and there is no fear of the theft of the portable terminal 114 being notified to the portable device 113. Is not done.

  If it is determined in step S103 that communication with the portable device 113 cannot be performed, the notification to the portable device 113 cannot be performed, and thus the processing in steps S104 and S105 is skipped, and the theft detection processing ends.

  Note that the determination process in step S103 may be omitted, and notification to the portable device 113 may be attempted in step S105 regardless of whether communication with the portable device 113 is possible.

  Further, the predetermined range used for the determination in step S104 does not necessarily need to coincide with the room of the vehicle 102 as long as it includes the room of the vehicle 102. That is, the predetermined range may be the same as the room of the vehicle 102 or a range wider than the room of the vehicle 102 around the vehicle 102. Further, it is not necessary to completely include the interior of the vehicle 102, and even in the interior of the vehicle 102, a place where the possibility that the portable device 113 is present may be excluded.

  For example, when the user who has the portable device 113 is on the immediate side of the vehicle 102, it is considered easy to detect the theft of the portable terminal 114 in the vehicle. Therefore, it is conceivable to set the predetermined range to a range slightly larger than the interior of the vehicle 102. Thereby, for example, when a passenger gets off after the user who owns the portable device 113, when the passenger removes the portable terminal 114 from the charging pad 125, the portable terminal 114 may be stolen. It is possible to prevent erroneous notification.

(Second embodiment of theft detection processing by the portable terminal 114)
Next, a second embodiment of the process when the portable terminal 114 detects theft of the portable terminal 114 will be described with reference to the flowchart of FIG. This process is started, for example, when the mobile terminal 114 is installed on the charging pad 125, in other words, when the mobile terminal 114 is placed within a chargeable range of the charging pad 125.

  In the second embodiment, as compared with the first embodiment, the portable terminal 114 does not detect the position of the portable device 113 but uses the result of the position detection of the portable device 113 by the ECU 121. The point to do is different.

  Specifically, in step S151, the communication control unit 361 determines whether or not the result of position detection of the portable device 113 has been notified.

  Specifically, the position detection unit 213 of the ECU 121 detects the position of the portable device 113 by the above-described method at a predetermined timing. Here, for example, when the door of the vehicle 102 is locked or unlocked, when the door of the vehicle 102 is opened and closed, or when the window of the vehicle 102 is opened and closed, the user who owns the portable device 113 ( It is conceivable that the position of the portable device 113 is detected at the timing when the condition that there is a possibility of going out of the vehicle or entering the vehicle is detected. Alternatively, the position of the portable device 113 may be periodically detected.

  When the position detection is performed by the position detection unit 213, the communication control unit 211 of the ECU 121 carries a signal indicating the detection result (hereinafter referred to as a position detection signal) via the NFC communication unit 251 of the charging pad 125. Transmit to terminal 114. When the communication control unit 352 of the portable terminal 114 receives the position detection signal from the charging pad 125 via the NFC communication unit 356, the communication control unit 352 determines that the result of the position detection of the portable device 113 has been notified, and the processing is step. The process proceeds to S152.

  In step S152, the communication control unit 361 updates the result of position detection of the portable device 113. That is, the communication control unit 361 updates the position detection result of the portable device 113 stored in the storage unit 353 to the latest detection result notified in the process of step S151.

  Thereafter, the process proceeds to step S153.

  On the other hand, if it is determined in step S151 that the position detection result of the portable device 113 has not been notified, the process of step S152 is skipped, and the process proceeds to step S153.

  In step S153, it is determined whether or not the portable terminal 114 is detached from the charging pad 125, as in the process of step S101 of FIG. If it is determined that the mobile terminal 114 is not detached from the charging pad 125, the process returns to step S151.

  Thereafter, the processes in steps S151 to S153 are repeatedly executed until it is determined in step S153 that the mobile terminal 114 has been detached from the charging pad 125.

  On the other hand, if it is determined in step S153 that the mobile terminal 114 has been detached from the charging pad 125, the process proceeds to step S154.

  In step S154, the position detection unit 364 determines whether the portable device 113 is within a predetermined range based on the latest position detection result of the portable device 113 stored in the storage unit 353. If it is determined that the portable device 113 does not exist within the predetermined range, the process proceeds to step S155.

  Here, for example, the ECU 121 detects whether or not the portable device 113 is within a predetermined range, and the position detection unit 364 performs the determination based on the detection result. Also good. Alternatively, for example, the position detection unit 364 may perform the determination based on the result of the position detection of the ECU 121 (for example, the distance to the mobile terminal 114 or the area where the mobile terminal 114 exists).

  In step S155, similar to the process in step S105 of FIG. 8, notification to the portable device 113 is performed, and the theft detection process ends.

  On the other hand, if it is determined in step S154 that the portable device 113 is within the predetermined range, the process in step S155 is skipped, and the theft detection process ends.

  Thereby, for example, even when the portable terminal 114 does not have the position detection function of the portable device 113, it is possible to detect the possibility of the theft of the portable terminal 114 and notify the portable device 113 of it.

(First embodiment of theft detection processing by the in-vehicle system 111)
Next, a first embodiment of processing when the in-vehicle system 111 detects the theft of the portable terminal 114 will be described with reference to the flowchart of FIG. This process is started, for example, when the mobile terminal 114 is installed on the charging pad 125, in other words, when the mobile terminal 114 is placed within a chargeable range of the charging pad 125.

  In step S201, it is determined whether or not the mobile terminal 114 has been detached from the charging pad 125, as in the process of step S4 of FIG. This determination process is periodically repeated until, for example, it is determined that the mobile terminal 114 is detached from the charging pad 125. And when it determines with the portable terminal 114 having removed from the charging pad 125, a process progresses to step S152.

  In step S202, the ECU 121 detects the position of the portable device 113. Specifically, the device detection unit 253 of the charging pad 125 notifies the ECU 121 that the mobile terminal 114 has been detached from the charging pad 125. The position detection unit 213 of the ECU 121 detects the position of the portable device 113 by the method described above.

  In step S203, the position detection unit 213 of the ECU 121 determines whether or not the portable device 113 is within a predetermined range. If it is determined that the portable device 113 does not exist within the predetermined range, the process proceeds to step S204.

  The predetermined range is set to a range similar to the range in step S104 of FIG.

  In step S204, the ECU 121 notifies the portable device 113, and the theft detection process ends. Specifically, the wireless communication unit 202 of the ECU 121 controls a predetermined signal (hereinafter referred to as a theft notification signal B) for notifying that the portable terminal 114 may be stolen under the control of the communication control unit 211. ) To the portable device 113.

  At this time, the theft notification signal B can be transmitted farther by using 900 MHz band wireless communication via the antenna 124.

  The communication control unit 311 of the portable device 113 receives the theft notification signal B from the ECU 121 via the wireless communication unit 305. And as above-mentioned, the portable device 113 notifies that there exists a possibility of theft of the portable terminal 114 in the vehicle 102 by a predetermined method.

  On the other hand, if it is determined in step S203 that the portable device 113 is within the predetermined range, the process of step S204 is skipped, and the theft detection process by the in-vehicle system 111 ends.

  In this way, by notifying the portable device 113 using the ECU 121, the range in which the possibility of theft of the portable terminal 114 can be notified is expanded compared to the case of notifying using the portable terminal 114. it can.

(Second embodiment of theft detection processing by the in-vehicle system 111)
Next, a second embodiment of the theft detection process executed by the in-vehicle system 111 will be described with reference to the flowchart of FIG. This process is started, for example, when the mobile terminal 114 is installed on the charging pad 125, in other words, when the mobile terminal 114 is placed within a chargeable range of the charging pad 125.

  In the second embodiment, the timing for detecting the position of the portable device 113 is different from that in the first embodiment.

  Specifically, in step S251, the position detection unit 213 of the ECU 121 determines whether it is time to detect the position of the portable device 113. If it is determined that it is time to detect the position of the portable device 113, the process proceeds to step S252.

  An example of timing for detecting the position of the portable device 113 is as described above in the process of step S151 in FIG.

  In step S252, the position of the portable device 113 is detected in the same manner as in step S202 of FIG.

  In step S253, the position detection unit 213 of the ECU 121 updates the result of position detection of the portable device 113. That is, the position detection unit 213 updates the position detection result of the portable device 113 stored in the storage unit 203 to the latest detection result detected in the process of step S252.

  Thereafter, the process proceeds to step S254.

  On the other hand, if it is determined in step S251 that it is not time to detect the position of the portable device 113, the processes in steps S252 and S253 are skipped, and the process proceeds to step S254.

  In step S254, it is determined whether or not the mobile terminal 114 is detached from the charging pad 125, as in the process of step S4 of FIG. If it is determined that the mobile terminal 114 is not detached from the charging pad 125, the process returns to step S251.

  Thereafter, the processes in steps S251 to S254 are repeatedly executed until it is determined in step S254 that the mobile terminal 114 is disconnected from the charging pad 125.

  On the other hand, if it is determined in step S254 that the mobile terminal 114 has been detached from the charging pad 125, the process proceeds to step S255.

  In step S <b> 255, the position detection unit 213 determines whether the portable device 113 is within a predetermined range based on the latest position detection result of the portable device 113 stored in the storage unit 203. If it is determined that the portable device 113 does not exist within the predetermined range, the process proceeds to step S256.

  In step S256, similar to the process in step S204 of FIG. 10, notification to the portable device 113 is performed, and the theft detection process ends.

  On the other hand, if it is determined in step S255 that the portable device 113 is within the predetermined range, the process in step S256 is skipped, and the theft detection process by the portable terminal 114 ends.

<2. Modification>
Hereinafter, modifications of the above-described embodiment of the present invention will be described.

[Modification 1: Modification regarding theft detection processing]
For example, the theft detection process by the mobile terminal 114 in FIG. 8 or FIG. 9 and the theft detection process by the in-vehicle system 111 in FIG. 10 or 11 may be executed in parallel. That is, the mobile terminal 114 and the in-vehicle system 111 (ECU 121) may detect the possibility of the theft of the mobile terminal 114 and notify the mobile device 113 of it.

  Further, for example, assuming that the theft detection and notification of the mobile terminal 114 is not necessary, the user operates the mobile terminal 114, so that the theft detection function of the mobile terminal 114 (for example, the transmission function of the theft notification signal A, etc.) ) On (start) or off (stop) may be set.

  Similarly, the user may be able to set on (start) or off (stop) the theft detection function of the ECU 121 (for example, the transmission function of the theft notification signal B). In this case, for example, the user may be able to perform the setting by remote operation by transmitting a command from the portable device 113 to the ECU 121 using the portable device 113. For example, the user may be able to perform the setting by remote operation by transmitting a command from the mobile terminal 114 to the ECU 121 using the mobile terminal 114 while the mobile terminal 114 is being charged. Further, the user may be able to perform the setting by operating the operation unit 112 of the vehicle 102.

  For example, the mobile terminal 114 may be charged only while the engine of the vehicle 102 (in the case of an engine car or a hybrid car) or the motor (in the case of an electric car or the like) is being activated. Further, for example, the charging / disabling of charging of the mobile terminal 114 may be controlled based on the power state of the vehicle 102 (for example, an accessory power source or an ignition power source is on or off). Furthermore, you may make it charge the portable terminal 114, only when the remaining amount of the battery (not shown) of the vehicle 102 is more than a predetermined threshold value.

[Variation 3: Variation regarding charging pad 125]

You may make it control supply of these.

  Further, for example, a processor such as a CPU may be provided on the charging pad 125 so that the charging pad 125 operates autonomously without being controlled by the ECU 121. In this case, for example, in-vehicle network communication such as CAN (Controller Area Network) can be adopted for communication between the charging pad 125 and the ECU 121.

  Further, for example, the ECU 121 may be provided with the same function as the device detection unit 253 of the charging pad 125. In this case, the device detection unit 253 of the charging pad 125 may be omitted.

  In addition, for example, a contact charger can be used instead of the non-contact charge pad 125. In this case, for example, a wired communication method may be employed instead of the proximity wireless communication as the charger communication method.

[Modification 4: Modification regarding communication method]
The example of the communication method between the devices shown in the above description is an example, and the type and number of communication methods are not limited to the above-described example.

  For example, as a communication method between the portable device 113 and the portable terminal 114, other short-range wireless communication such as Bluetooth (registered trademark) is adopted, or a communication method having a longer communication distance than short-range wireless communication is adopted. It is possible to

  In addition, for example, proximity wireless communication of a method other than NFC can be adopted as a communication method between the mobile terminal 114 and the charging pad 125. Furthermore, for example, the communication function between the portable terminal 114 and the charging pad 125 can be omitted as necessary.

[Modification 5: Other Modifications]
The method of detecting the position of the portable device 113 based on the communication state between the portable device 113 and the ECU 121 by the ECU 121 is not limited to the method described above, and other methods can be adopted. Also, the method of detecting the position of the portable device 113 based on the communication state between the portable device 113 and the portable terminal 114 by the ECU 121 is not limited to the above-described method, and other methods can be adopted.

  Furthermore, the type of vehicle to which the present invention is applied is not particularly limited as long as a charging device capable of charging the mobile terminal 114 can be installed.
