In this way, locking or unlocking of a vehicle door using the smartphone 1 is performed.

  The vehicle in this embodiment includes a center console. As shown in FIG. 2, the center console is provided with a mounting device 23 called a dock for mounting the smartphone 1. A vehicle interior NFC reader 21c is incorporated in a region A indicated by a dotted line in FIG.

  When the user starts the engine of the vehicle, after getting on the vehicle, the user attaches the smartphone 1 to the mounting device 23 provided on the vehicle, and presses the start switch 20 while stepping on the brake.

  When the start switch 20 is pressed in this way, a transmission request for authentication data (key information) is transmitted from the vehicle interior NFC reader 21c to the smartphone 1 by radio wave transmission. Data (key information) for authentication is transmitted to 2. The control unit 22 authenticates the smartphone 1 based on the data transmitted from the smartphone 1, and transmits a start permission for starting the engine of the vehicle to the engine ECU 4 when the authentication result is good. Upon receiving this start permission, the engine ECU 4 drives the cell motor to start the vehicle engine.

  When the smartphone 1 in the present embodiment is mounted on the mounting device 23, it is then determined whether or not a removal operation from the mounting device 23 has been performed, and when it is determined that a removal operation from the mounting device 23 has been performed, A removal information notification process for notifying the vehicle-mounted device 2 of removal information indicating that a removal operation from the mounting device 23 has been performed is performed.

  A flowchart of the removal information notification process is shown in FIG. When the control unit 19 of the smartphone 1 determines that it is mounted on the mounting device 23 based on information transmitted from the control unit 22 of the in-vehicle device 2 via the vehicle interior NFC reader 21c provided in the mounting device 23, The process shown in FIG. 3 is periodically performed.

  First, based on whether or not the acceleration sensor 13 detects an acceleration equal to or higher than a reference value, it is determined whether or not a removal operation from the mounting device 23 has been performed (S100).

  Here, for example, when the user removes the smartphone 1 from the wearer 23 and the acceleration sensor 13 detects an acceleration equal to or higher than the reference value, the determination in S100 is YES, and then the removal operation from the wearer 23 is performed. Removal information indicating that this has been done is notified to the in-vehicle device 2 (S102). In this embodiment, removal information is notified to the vehicle-mounted apparatus 2 via NFC communication, and this process is complete | finished.

  If the acceleration sensor 13 does not detect acceleration equal to or higher than the reference value, the determination in S100 is NO, and then, based on whether the proximity sensor 14 detects the proximity of the detection target, it is determined from the mounting device 23. It is determined whether or not a removal operation has been performed (S104).

  Here, for example, when the proximity sensor 14 detects the proximity of the user's hand when the user removes the smartphone 1 from the wearer 23, the determination in S104 is YES and the removal information is notified to the in-vehicle device 2. (S102).

  If the proximity sensor 14 does not detect the proximity of the detection target, the determination in S104 is NO, and then, based on whether the touch sensor 15 detects a touch operation on the display surface, the wearer It is determined whether or not the removal operation from 23 has been performed (S106).

  Here, for example, when the user removes the smartphone 1 from the wearer 23, if a touch operation by the user's hand on the display surface is detected by the touch sensor 15, the determination in S106 is YES, and the removal information is in-vehicle. The device 2 is notified (S102).

  When the touch operation by the user's hand on the display surface is not detected by the touch sensor 15, the determination in S106 is NO, and this process is terminated without the removal information being notified to the in-vehicle device 2.

  As described above, when acceleration equal to or higher than the reference value is detected by the acceleration sensor 13, when proximity of the user's hand is detected by the proximity sensor 14, and touch by the user's hand to the display surface by the touch sensor 15. When it corresponds to any of the cases where the operation is detected, it is determined that the removal operation from the mounting device 23 has been performed, and the removal information is notified from the smartphone 1 to the in-vehicle device 2.

  The in-vehicle device 2 in this embodiment mobile phone reduces the power consumption of the battery of the mobile terminal and avoids a situation in which the vehicle cannot run due to the mobile terminal being taken out of the vehicle. It is determined whether or not there is a possibility of being taken out, and if it is determined that the smartphone 1 may be taken out of the vehicle from the inside of the vehicle, the presence / absence of the smartphone 1 is confirmed via the vehicle interior NFC reader 21c. When this access is abnormally terminated, a notification process for performing notification for prompting the occupant to confirm the smartphone 1 is performed.

  In FIG. 4, the flowchart of the alerting | reporting process by the control part 22 of the vehicle-mounted apparatus 2 is shown. As described above, the in-vehicle device 2 permits the start of the engine of the vehicle using the smartphone 1, and periodically executes the processing shown in FIG. 4 when the engine of the vehicle is started by the engine ECU.

  First, it is determined whether or not the smartphone 1 is likely to be taken out of the vehicle based on whether or not at least one door of the vehicle is open (S200). Since the passenger may get off with the smartphone when the door of the vehicle is open, such a determination is performed. Whether the vehicle door is open or closed can be determined based on a signal output from a courtesy switch (not shown) that outputs a signal corresponding to the open / closed state of the vehicle door. .

  Here, if the vehicle door is closed, the determination in S200 is NO, and then whether or not at least one of the vehicle windows is open and the vehicle is stopped. Based on the above, it is determined whether or not the smartphone 1 may be taken out of the vehicle from inside the vehicle (S202).

  In a stopped vehicle, the smartphone 1 may be taken out of the passenger compartment through the window of the vehicle, so such a determination is performed. As to whether the vehicle window is open or closed, a signal indicating whether the vehicle window is open or closed is sent from an ECU (not shown) that controls opening and closing of the vehicle window. It can be acquired and determined based on the acquired signal. Further, whether the vehicle is stopped or traveling can be determined based on a vehicle speed signal output from a vehicle speed sensor (not shown) for detecting the vehicle speed of the vehicle.

  Here, when all the windows of the vehicle are closed and the vehicle is running, it is determined that the smartphone 1 is not likely to be taken out of the vehicle, that is, the determination in S204. NO is determined, and then it is determined whether or not the smartphone 1 may be taken out of the vehicle based on whether or not the removal information is received from the smartphone 1 (S204). Here, when removal operation from the mounting device 23 is not performed and removal information is not received from the smart phone 1, determination of S204 becomes NO and this process is complete | finished.

  However, when at least one door of the vehicle is open, it is determined that the smartphone 1 may be taken out of the vehicle from the inside of the vehicle, that is, the determination in S200 is YES, and the process proceeds to S206.

  Further, when at least one of the windows of the vehicle is open and the vehicle is stopped, it is determined that the smartphone 1 may be taken out of the vehicle from the inside of the vehicle, that is, S202. The determination is YES, and the process proceeds to S206.

  Also, when removal information is received from the smartphone 1, it is determined that the smartphone 1 may be taken out of the vehicle from the inside of the vehicle, that is, the determination in S204 is YES, and the process proceeds to S206.

  In S206, battery remaining amount specifying information and charging state specifying information are acquired from the smartphone 1 (S206). The battery remaining amount specifying information indicates the remaining amount of the battery of the smartphone 1 in four stages of “FULL”, “MID”, “LOW”, and “VERY LOW”. Moreover, charge state specific information is the information for specifying whether the battery of the smart phone 1 is charging.

  Next, the remaining battery level of the smartphone 1 is specified based on the remaining battery level specifying information, and it is determined whether or not the remaining battery level of the smartphone 1 is equal to or less than a reference value (S208). In this embodiment, the determination threshold of “FULL” and “MID” is used as a reference value to determine whether the remaining battery level is equal to or less than the reference value.

  Here, when the remaining battery level of the smartphone 1 is “FULL”, the determination in S208 is NO, and the smartphone has a predetermined time interval T1 (for example, T1 = 1 minute) for a predetermined period. NFC access for confirming the presence or absence of 1 is performed (S210). Specifically, a transmission request for data (key information) for authentication is transmitted from the in-vehicle NFC reader 21c to the smartphone 1 at a first time interval T1 for a predetermined period, and the reception of this radio wave is performed. In response, the vehicle interior NFC reader 21c reads data for authentication (key information) transmitted from the smartphone 1 to the in-vehicle device 2. In addition, the control part 22 memorize | stores the data read by the vehicle interior NFC reader 21c in RAM.

  Note that the period during which the NFC access is periodically performed is shorter than the execution cycle of the flowchart of FIG. In addition, when the vehicle door is in the open state, a period during which the NFC access is periodically performed is a period until the vehicle door is in the closed state.

  Next, it is determined whether or not the NFC access is abnormal (S220). Specifically, in S210, it is determined whether or not NFC access is abnormal based on whether or not authentication data (key information) to be transmitted from the smartphone 1 is normally stored in the RAM. To do.

  Here, when the smartphone 1 is not taken out of the passenger compartment and the authentication data (key information) transmitted from the smartphone 1 is normally stored in the RAM, the determination in S220 is NO, and the passenger is informed. This processing is terminated without carrying out notification for prompting confirmation of the smartphone 1.

  When the smartphone 1 is taken out of the passenger compartment and the data for authentication (key information) to be transmitted from the smartphone 1 is not normally stored in the RAM, the determination in S220 is YES, and the smartphone 1 Notification for prompting confirmation is performed (S222).

  Specifically, a message that prompts confirmation of the smartphone 1 is displayed on the display unit of the navigation device 5, and a message prompting confirmation of the smartphone 1 is output from a speaker connected to the navigation device 5, and this processing ends. .

  In addition, when the remaining battery level of the smartphone 1 is “MID”, “LOW”, or “VERY LOW”, that is, when the remaining battery level of the smartphone 1 is below the reference value, The determination in S206 is YES, and then it is determined whether the battery of the smartphone 1 is being charged (S212). Whether or not the battery of the smartphone 1 is being charged can be determined based on the charging state specifying information.

  Here, when the battery of the smartphone 1 is not being charged, the determination in S212 is NO, and next, travel route information is acquired from the navigation device (S214). The travel route information includes a guide route from the destination and departure point (current position) to the destination, and a route length of the guide route.

  Next, it is determined whether or not the vehicle is traveling from near home to home (S216). Specifically, when the home is set as the destination based on the travel route information and the distance between the current position of the vehicle and the home is determined to be less than or equal to the reference value, the vehicle moves from near the home to the home. To determine whether the vehicle is running.

  Here, even when the home is not set as the destination, or even when the home is set as the destination, if the distance between the current position of the vehicle and the home is longer than the reference value, the determination in S216 is NO. Next, access for confirming the presence / absence of the smartphone 1 is performed at a time interval longer than the time interval T1 for a predetermined period (S218).

  Specifically, a transmission request for authentication data (key information) is transmitted from the vehicle interior NFC reader 21c to the smartphone 1 at a time interval longer than the time interval T1 for a predetermined period. Data (key information) for authentication transmitted from the smartphone 1 to the in-vehicle device 2 in response to reception is read by the vehicle interior NFC reader 21c. In addition, the interval of access for confirming the presence or absence of the smart phone 1 is lengthened, so that the remaining amount of the battery of the smart phone 1 decreases.

  In this embodiment, when the remaining amount of the battery of the smartphone 1 is “MID”, access for confirming the presence / absence of the smartphone 1 is performed at a second time interval T2 longer than the first time interval T1. When the remaining battery level of the smartphone 1 is “LOW”, the access for confirming the presence / absence of the smartphone 1 is performed at the third time interval T3 longer than the second time interval T2. It has become.

  In addition, the control unit 22 stores the data read by the vehicle interior NFC reader 21c in the RAM. Thus, if the access for confirming the presence or absence of the smart phone 1 is implemented, it will progress to S220.

  In addition, even if the remaining battery level of the smartphone 1 is “MID”, “LOW”, or “VERY LOW” and it is determined YES in S208, the battery of the smartphone 1 is being charged. If it is determined YES in S212, the process proceeds to S210, and NFC access for confirming the presence / absence of the smartphone 1 at a first time interval T1 (for example, T1 = 1 minute) for a predetermined period. To implement. When the battery of the smartphone 1 is being charged, since it is unlikely that the remaining battery level of the mobile terminal is reduced and the mobile terminal cannot be used, the presence / absence of the smartphone 1 at a relatively short first time interval T1 NFC access is performed to confirm this.

  In addition, even if the remaining battery level of the smartphone 1 is “MID”, “LOW”, or “VERY LOW” and it is determined YES in S208, the home is set as the destination, and When it is determined that the distance between the current position of the vehicle and the home is equal to or less than the reference value and it is determined YES in S216, the process proceeds to S210, and the first time interval T1 (first time interval T1 ( For example, NFC access for confirming the presence or absence of the smartphone 1 is performed at T1 = 1 minute). As described above, even when the home is set as the destination and the distance between the current position of the vehicle and the home is equal to or less than the reference value, the battery of the smartphone 1 can be charged by returning to the home. The NFC access for confirming the presence or absence of the smartphone 1 is performed at a relatively short first time interval T1.

  According to the configuration described above, the in-vehicle device 2 determines whether or not the smartphone 1 may be taken out of the vehicle from the inside of the vehicle, and the smartphone 1 may be taken out of the vehicle from the inside of the vehicle. If it is determined, access for confirming the presence or absence of the smartphone 1 is performed via the vehicle interior NFC reader 21c, and when the access is abnormally terminated, a notification is made to prompt the occupant to confirm the smartphone 1; While reducing power consumption, it is possible to avoid a situation in which the vehicle cannot travel due to the portable terminal being taken out of the vehicle.

  When the door open determining means determines that at least one door of the vehicle is open, it is determined that at least one of the vehicle windows is open and the vehicle is stopped. If the removal information indicating that the removal operation from the mounting device 23 has been performed is received from the smartphone 1, the smartphone 1 may be taken out of the vehicle from the vehicle when at least one condition is satisfied. It can be determined that there is.

  Further, in the smartphone 1, when the acceleration sensor 13 detects an acceleration equal to or higher than the reference value, when the proximity sensor 14 detects the proximity of the detection target, the touch sensor 15 detects the touch operation on the display surface. When at least one of the conditions is satisfied, the in-vehicle device 2 can be notified of the removal information indicating that the removal operation from the mounting device 23 has been performed.

  Moreover, the vehicle-mounted apparatus 2 can implement the access for confirming the presence or absence of the smart phone 1 at a predetermined first time interval for a predetermined period.

  Further, the in-vehicle device 2 specifies the remaining battery level of the smartphone 1, and when the remaining battery level of the smartphone 1 is equal to or lower than the reference value, access for confirming the presence or absence of the smartphone 1 is performed at the first time interval. Therefore, it is possible to prevent the remaining amount of the battery of the smartphone 1 from being quickly reduced.

  Moreover, since the vehicle-mounted apparatus 2 lengthens the access interval for confirming the presence / absence of the smartphone 1 as the remaining amount of the battery of the smartphone 1 decreases, the remaining amount of the battery of the smartphone 1 is prevented from rapidly decreasing. However, it is possible to avoid a situation in which the vehicle cannot travel due to the portable terminal being taken out of the vehicle.

  In addition, even when the remaining amount of the battery of the smartphone 1 is equal to or less than the reference value, the in-vehicle device 2 performs access for checking the presence or absence of the smartphone 1 when it is determined that the battery of the smartphone 1 is being charged. The first time interval can be implemented.

  Moreover, even when the remaining battery level of the smartphone 1 is equal to or less than the reference value, the in-vehicle device 2 sets the home as the destination based on the travel route information, and the distance between the current position of the vehicle and the home is the reference value. If it is determined that it is below, access for confirming the presence or absence of the smartphone 1 can be performed at the first time interval.

  In addition, this invention is not limited to the said embodiment, Based on the meaning of this invention, it can implement with a various form.

  For example, in the above embodiment, a vehicle using an engine as a driving power source is shown as an example. However, a hybrid vehicle using an engine and a motor as a driving power source, and a motor as a driving power source. It can also be applied to electric vehicles and the like.

  Moreover, although the said embodiment demonstrated the structure using the smart phone 1 as a portable terminal which has the near field communication function 3, as a portable terminal, it is not limited to a smart phone, For example, it has a near field communication function. A mobile phone, a tablet terminal, a PDA terminal, or the like can also be used.

  In the above embodiment, the acceleration sensor 13 detects an acceleration that is equal to or higher than the reference value, the proximity sensor 14 detects the proximity of the user's hand, and the touch sensor 15 detects the user's hand on the display surface. In the case where any of the contact operations is detected, it is determined that the removal operation from the mounting device 23 has been performed, and the configuration in which the removal information is notified from the smartphone 1 to the in-vehicle device 2 is shown. For example, when the smartphone 1 receives an incoming call, the removal information may be notified from the smartphone 1 to the in-vehicle device 2.

  In addition, a vibration detection sensor (for example, a vibration sensor) that detects vibration is provided in the smartphone 1, and it is determined by this vibration detection sensor that a specific vibration that occurs when the smartphone 1 is removed from the wearer 23 is detected. In such a case, the removal information may be notified from the smartphone 1 to the in-vehicle device 2.

  Moreover, in the said embodiment, although authentication with respect to the smart phone 1 was implemented by near field communication according to NFC standard, it is not necessarily limited to near field communication according to NFC standard.

  In the above embodiment, when the removal information is notified from the smartphone 1 to the in-vehicle device 2, the in-vehicle device 2 is notified via the NFC communication. However, the communication other than the NFC communication installed in the mobile terminal is used. You may comprise so that the vehicle-mounted apparatus 2 may be notified via means, for example, Bluetooth, WiFi, infrared communication, etc.
