<Operation of First Embodiment>
Next, the operation of the auto light control system 10 of the first embodiment will be described. FIG. 3 is an operation flowchart of the auto light control system 10 of the first embodiment.

  When automatically controlling the headlight 130 or the like of the vehicle 100 using the mobile terminal 200, the user operates the display operation unit 222 and selects auto light control (step S1).

  Next, the user installs the mobile terminal 200 in the terminal installation unit 112 after performing initial settings for autolight control (step S2). In this initial setting, an illuminance threshold for determining whether to turn on or off the headlight 130 of the vehicle 100 is set. The set threshold value is stored in a RAM (not shown) of the control unit 202. If the threshold has already been set, the process of step S2 may be omitted.

  As the threshold values, a threshold value for determining whether the headlight 130 is turned on, a threshold value for determining whether the headlight 130 is turned off, a threshold value for determining whether the small light 132 is turned on, and a threshold value for determining whether the small light 132 is turned off are set. It is preferable that the threshold for determining whether the headlight 130 or the like is turned on is set smaller than the threshold for determining whether the headlight 130 or the like is turned off. By setting the threshold value in this way, the light control signal generation unit 226 can generate a light control signal for lighting the headlight 130 and the like in a brighter situation than when the light is turned off, so that a delay in lighting is prevented. For example, the user can display a plurality of threshold candidates on the display operation unit 222, and the user can select and set a desired threshold from among them.

In this way, the user can easily set a desired threshold using the display operation unit 222 of the mobile terminal 200, and can finely adjust the timing of turning on / off the headlight 130 and the like.

  For example, the portable terminal 200 can be installed in the terminal installation unit 112 in a predetermined posture, or can be installed in the holder when the terminal installation unit 112 is provided with a holder. When performing wired communication between the portable terminal 200 and the vehicle 100, the wired communication unit 206 of the portable terminal 200 and the wired communication unit 122 of the vehicle 100 are connected using a connector, cable, or cradle (not shown). Further, when wireless communication is performed between the mobile terminal 200 and the vehicle 100, the connection is established by performing communication between the wireless communication unit 208 of the mobile terminal 200 and the wireless communication unit 124 of the vehicle 100. In this case, the user can easily install and connect the mobile terminal 200 to the vehicle 100 without having special knowledge about the type of the vehicle 100 to be connected or the autolight control system 10.

  After the initially set mobile terminal 200 is installed in the terminal installation unit 112, the control unit 202 transmits a vehicle state information request signal to the vehicle 100 in order to acquire vehicle state information (step S3).

  The vehicle state information is, for example, the position of the terminal installation unit 112 detected by the GPS receiver 134, the acceleration calculated from the speed detected by the speed sensor 136, the acceleration detected by the acceleration sensor 138, or the gyro sensor 140. The detected angular velocity. The absolute position of the terminal installation unit 112 is obtained, for example, by previously acquiring the relative position of the terminal installation unit 112 with respect to the specific position of the vehicle 100 and the absolute position of the specific position detected by the GPS receiver 134 and the terminal installation. It can be calculated from the relative position of the unit 112.

  When the portable terminal 200 and the vehicle 100 are connected by wire via the wired communication units 206 and 122, the control unit 202 transmits a vehicle state information request signal to the vehicle 100 via a connector or cable (not shown).

  When the mobile terminal 200 and the vehicle 100 are wirelessly connected via the wireless communication units 208 and 124, the control unit 202 transmits the authentication information of the mobile terminal 200 to the wireless communication unit prior to transmission of the vehicle state information request signal. The data is transmitted from 208 to the vehicle 100. The control unit 120 that has received the authentication information from the mobile terminal 200 via the wireless communication unit 124 authenticates that the mobile terminal 200 is appropriate, and then receives a vehicle state information request signal. For example, in wireless communication using WiFi, the control unit 120 performs an authentication process based on the SSID transmitted from the mobile terminal 200. In wireless communication using bluetooth (registered trademark), the control unit 120 performs authentication processing by pairing between the mobile terminal 200 and the vehicle 100. In wireless communication using WiMAX, the control unit 120 performs authentication processing based on the MAC address. Furthermore, in wireless communication using infrared rays, the control unit 120 performs an authentication process based on the authentication code transmitted from the mobile terminal 200.

  When the light switch 116 is not operated by the user (NO in step S4), the control unit 120 is mounted on the vehicle 100 when receiving the vehicle state information request signal transmitted from the mobile terminal 200 (YES in step S5). Vehicle state information is acquired from each sensor. And the control part 120 transmits vehicle state information to the portable terminal 200 via the wired communication part 122 or the wireless communication part 124 (step S6).

  After transmitting vehicle state information to portable terminal 200, control unit 120 waits for a light control signal for performing autolight control when no autolight control release signal is received (step S7 NO). (Step S8 NO).

  When receiving the vehicle state information, the control unit 202 acquires the terminal state information from each sensor and each detection unit mounted on the mobile terminal 200. The installation state determination unit 224 determines whether the mobile terminal 200 is installed in the terminal installation unit 112 in an appropriate installation state based on at least one of the vehicle state information related to the vehicle 100 or the terminal state information related to the mobile terminal 200. Determine (step S9). When the portable terminal 200 is not installed in an appropriate installation state, the illuminance sensor 204 may not be able to detect an appropriate illuminance around the vehicle, and the light control signal generation unit 226 detects the headlight 130 of the vehicle 100 and the like. This is because a write control signal for appropriate control cannot be generated.

  The terminal state information includes, for example, the position of the mobile terminal 200 detected by the GPS receiver 214, the acceleration detected by the acceleration sensor 216, the angular velocity detected by the gyro sensor 218, and the mobile terminal detected by the proximity sensor 220. 200, the connection state between the wired communication unit 206 and the wired communication unit 122 detected by the connection state detection unit 228, and the signal received by the wireless communication unit 208 detected by the signal strength detection unit 230. The signal intensity or the charging state of the battery 212 by the non-contact charging circuit 210 detected by the charging state detection unit 232 is shown.

  The installation state determination unit 224 can determine whether or not the mobile terminal 200 is installed at a position shifted from the terminal installation unit 112. Further, the installation state determination unit 224 can determine whether or not the mobile terminal 200 is installed in an inappropriate posture on the terminal installation unit 112. Furthermore, the installation state determination unit 224 can determine whether or not the mobile terminal 200 is greatly displaced from the terminal installation unit 112, for example, dropped from the terminal installation unit 112. Furthermore, the installation state determination unit 224 can determine whether or not the user has brought a hand or the like close to the illuminance sensor 204 of the mobile terminal 200 to cover the light receiving unit, and the illuminance cannot be appropriately detected.

  Examples of the installation state determination method by the installation state determination unit 224 include the following methods.

  As an example, the installation state determination unit 224 determines the installation state based on the position of the terminal installation unit 112 and the position of the mobile terminal 200 detected by the GPS receiver 214. For example, the installation state determination unit 224 obtains a difference value between these positions. When the difference value is within the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is installed at an appropriate position of the terminal installation unit 112. On the other hand, when the difference value is outside the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is displaced from the terminal installation unit 112. If the difference value is outside the allowable range and the difference value is larger than the predetermined value, the installation state determination unit 224 indicates that the mobile terminal 200 is not installed in the terminal installation unit 112 or the terminal It can also be determined that it is falling from the installation unit 112.

  Further, the installation state determination unit 224 determines the installation state based on the acceleration of the vehicle 100 and the acceleration of the mobile terminal 200 detected by the acceleration sensor 216. For example, the installation state determination unit 224 determines the difference between the acceleration in each axial direction of the orthogonal coordinate system of the acceleration sensor 138 of the vehicle 100 and the acceleration in the corresponding axial direction of the orthogonal coordinate system of the acceleration sensor 216 of the mobile terminal 200. Ask for. When the difference value is within the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is installed in an appropriate posture on the terminal installation unit 112. On the other hand, when the difference value is outside the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in an appropriate posture on the terminal installation unit 112.

  In addition, the installation state determination unit 224 determines the installation state based on the angular velocity of the vehicle 100 and the angular velocity of the mobile terminal 200 detected by the gyro sensor 218. For example, the installation state determination unit 224 determines a difference value between an angular velocity in each axial direction of the orthogonal coordinate system of the gyro sensor 140 of the vehicle 100 and a corresponding angular velocity of the orthogonal coordinate system of the gyro sensor 218 of the mobile terminal 200. Ask for. When the difference value is within the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is installed in an appropriate posture on the terminal installation unit 112. On the other hand, when the difference value is outside the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in an appropriate posture on the terminal installation unit 112.

  Further, the installation state determination unit 224 determines the installation state based on the detection result by the proximity sensor 220 of the mobile terminal 200. For example, when the proximity sensor 220 detects that the mobile terminal 200 has approached the terminal installation unit 112, the installation state determination unit 224 determines that the mobile terminal 200 is installed in the terminal installation unit 112 based on the detection result. judge. For example, when the proximity sensor 220 is a capacitance type sensor, when the object approaches the proximity sensor 220 and the capacitance as a result of detection by the proximity sensor 220 changes by a predetermined threshold or more, the installation state determination The unit 224 determines that the mobile terminal 200 is installed in the terminal installation unit 112. On the other hand, if no change in the capacitance of the proximity sensor 220 is detected, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in the terminal installation unit 112. Even if it is determined that the mobile terminal 200 is installed in the terminal installation unit 112, if the detection result of the proximity sensor 220 is further changed than when the mobile terminal 200 is installed, the installation state determination is performed. The unit 224 can determine that the user's hand is approaching the mobile terminal 200 installed in the terminal installation unit 112. In this case, the installation state determination unit 224 can determine that the user has approached the illuminance sensor 204 of the portable terminal 200 and the user's hand has closed the light receiving unit of the illuminance sensor 204 with his / her hand. Then, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in the terminal installation unit 112 in an appropriate installation state based on the detection result by the proximity sensor 220.

  Further, the installation state determination unit 224 determines the installation state based on the detection result by the connection state detection unit 228. The connection state detection unit 228 detects whether the wired communication unit 206 is connected to the wired communication unit 122 of the vehicle 100 via a connector or a cable. When the connection state of the wired communication units 206 and 122 is detected, the installation state determination unit 224 determines that the mobile terminal 200 is installed in the terminal installation unit 112. On the other hand, when the connection state of the wired communication units 206 and 122 is not detected, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in the terminal installation unit 112.

  The installation state determination unit 224 determines the installation state based on the detection result of the signal strength by the signal strength detection unit 230. The signal strength detection unit 230 detects the signal strength of the signal received by the wireless communication unit 208 from the wireless communication unit 124 of the vehicle 100. When the detected signal strength is within the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is installed in the terminal installation unit 112. On the other hand, when the detected signal strength is outside the allowable range, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in the terminal installation unit 112. In this case, if the communication means between the wireless communication units 208 and 124 is Wi-Fi, bluetooth (registered trademark), or WiMAX, the installation state determination unit 224 can determine based on the electric field strength detected as the signal strength. If the communication means between the wireless communication units 208 and 124 is infrared communication, the installation state determination unit 224 can determine based on the amount of infrared light detected as the signal intensity.

  The installation state determination unit 224 determines the installation state based on the detection result of the charge state by the charge state detection unit 232. The charging state detection unit 232 detects the charging state of the battery 212 by the non-contact charging circuit 210. When it is detected that the non-contact charging circuit 210 is charged by the non-contact charging circuit 126 of the vehicle 100 based on the charging state of the non-contact charging circuit 210, the installation state determination unit 224, based on the detection result, It is determined that the mobile terminal 200 is installed in the terminal installation unit 112. On the other hand, when the connection state of the non-contact charging circuit 210 is not detected, the installation state determination unit 224 determines that the mobile terminal 200 is not installed in the terminal installation unit 112.

  The installation state determination unit 224 can determine the installation state of the mobile terminal 200 relative to the terminal installation unit 112 more accurately by appropriately combining the above determination results.

  For example, when determining based on only the positions detected by the GPS receivers 134 and 214, the installation state determination unit 224 can determine whether or not the mobile terminal 200 is installed in the terminal installation unit 112. However, the installation state determination unit 224 cannot determine whether or not the mobile terminal 200 is installed in the terminal installation unit 112 in an appropriate posture from only the position information. Therefore, the installation state determination unit 224 determines the installation position determination result based on the positions detected by the GPS receivers 134 and 214 and the attitude of the mobile terminal 200 detected by the acceleration sensors 138 and 216 or the gyro sensors 140 and 218. Combined with the judgment result based on. Thereby, even if it is determined that the mobile terminal 200 is installed in the terminal installation unit 112, the installation state determination unit 224 determines that the mobile terminal 200 is suitable for the terminal installation unit 112 based on the acceleration or the angular velocity. It can be determined that it is not installed in a posture.

  In addition, the installation state determination unit 224 combines the position detected by the GPS receivers 134 and 214 and the signal strength of the signal detected by the signal strength detection unit 230, so that the terminal installation unit 112 of the vehicle 100 and the mobile terminal 200 are combined. It is possible to determine the installation state related to the distance between the two. Thereby, the installation state determination part 224 can determine the installation state of the portable terminal 200 effectively. For example, it is assumed that the mobile terminal 200 falls from the terminal installation unit 112 in a state where it is determined that the mobile terminal 200 is installed in the terminal installation unit 112 based on the positions detected by the GPS receivers 134 and 214. To do. Even if the mobile terminal 200 falls due to a problem in detection accuracy of the GPS receivers 134 and 214 and the mobile terminal 200 is separated from the terminal installation unit 112 by a predetermined distance or more, the installation state determination unit 224 There is a risk of misjudging that it is installed at the same latitude and longitude. In this case, even if it is determined that the mobile terminal 200 is installed in the terminal installation unit 112, if the signal strength is equal to or lower than the predetermined value, the installation state determination unit 224 causes the mobile terminal 200 to move from the terminal installation unit 112. It can be determined that it has fallen.

  Similarly, the installation state determination unit 224 includes the position detected by the GPS receivers 134 and 214, the acceleration detected by the acceleration sensors 138 and 216, the angular velocity detected by the gyro sensors 140 and 218, and the object detected by the proximity sensor 220. By appropriately combining the detection result, the connection state of the mobile terminal 200 detected by the connection state detection unit 228, the signal intensity detected by the signal strength detection unit 230, and the charge state detected by the charge state detection unit 232, The installation state with respect to 200 terminal installation units 112 can be determined more accurately.

  Next, when the installation state determination unit 224 determines that the mobile terminal 200 is installed in an appropriate state in the terminal installation unit 112 (step S9 OK), the installation state determination unit 224 instructs the light control signal generation unit 226 to generate a light control signal. To do. The light control signal generation unit 226 acquires illuminance data detected by the illuminance sensor 204 (step S10). In this case, since the mobile terminal 200 is installed in the terminal installation unit 112 in an appropriate state, the illuminance sensor 204 can detect appropriate illuminance data for determining whether the headlight 130 or the like is turned on or off.

  The light control signal generation unit 226 compares the threshold set in step S2 with the acquired illuminance data, and determines whether the headlight 130 or the like is on or off (step S11). Then, the light control signal generation unit 226 generates a light control signal for turning on and off the headlight 130 and the like based on the on / off determination result, and transmits the light control signal to the vehicle 100 (step S12).

  When the light control unit 150 receives the light control signal (YES in step S8), the light control unit 150 controls turning on and off the headlight 130 and the like of the vehicle 100 according to the light control signal. That is, when the light control signal is an ON signal for turning on the headlight 130 or the like (step S13 ON), the light control unit 150 turns on the headlight 130 or the like (step S14). When the light control signal is an off signal for turning off the headlight 130 or the like (step S13 OFF), the light control unit 150 turns off the headlight 130 or the like (step S15).

  Until the automatic light control is released by the user (YES in step S16), the installation state determination unit 224 determines the installation state of the mobile terminal 200 every predetermined time (step S9). When it is determined that the mobile terminal 200 is installed in the terminal installation unit 112 in an appropriate state (step S9 OK), the control unit 202 repeats the lighting / extinguishing control of the headlight 130 and the like of the vehicle 100 (step S3). ~ S16 NO).

  On the other hand, when the mobile terminal 200 is not installed in the terminal installation unit 112 in an appropriate state, the illuminance sensor 204 may not be able to properly detect the illuminance around the vehicle. Such a situation is, for example, when the position or posture of the mobile terminal 200 is shifted due to vibration of the traveling vehicle 100 during the automatic light control by the mobile terminal 200, or when the mobile terminal 200 falls from the terminal installation unit 112. Or, it occurs when the user covers the light receiving unit of the illuminance sensor 204 of the portable terminal 200 with his / her hand.

  If the installation state determination unit 224 determines that the mobile terminal 200 is not installed in the terminal installation unit 112 in an appropriate state (step S9 NG), the installation state determination unit 224 does not instruct the light control signal generation unit 226 to generate a light control signal. The installation state determination unit 224 cancels the auto light control by the mobile terminal 200 (step S17), and transmits a cancel signal to the vehicle 100 (step S18). In addition, when the user cancels the autolight control by the portable terminal 200 (step S16 YES), the control unit 202 transmits a cancel signal to the vehicle 100 (step S18).

  When the control unit 120 receives the release signal from the installation state determination unit 224 (YES in step S7), the control unit 120 stops the process of transmitting the vehicle state information to the portable terminal 200 and enters a state of waiting for the user to operate the light switch 116 ( Step S4). In this case, since the light control signal is not transmitted from the mobile terminal 200 to the vehicle 100, the headlight 130 or the like is erroneously controlled to be turned on / off by the light control signal based on the inappropriate illuminance detected by the illuminance sensor 204. Operation is prevented. For example, even when the mobile terminal 200 falls from the terminal installation unit 112 and moves to a place where the external light does not reach sufficiently, there is no possibility that the headlight 130 or the like is turned on.

  When the user operates the light switch 116 (YES in step S4), the light control unit 150 controls turning on and off of the headlight 130 and the like according to the operation of the light switch 116. That is, when the user performs an operation to turn on the headlight 130 or the like (step S19 ON), the light control unit 150 turns on the headlight 130 or the like (step S14). When the user performs an operation to turn off the headlight 130 or the like (step S19 OFF), the light control unit 150 turns off the headlight 130 or the like (step S15). For the lighting / extinguishing control of the headlight 130 and the like, the user's lighting / extinguishing operation has priority over the auto light control performed by the mobile terminal 200.

  If the installation state determination unit 224 determines that the mobile terminal 200 is not installed in an appropriate state in the terminal installation unit 112 (step S9 NG), the installation state determination unit 224 does not immediately transmit the autolight control release signal, You may make it perform the process for the warning with respect to a user in the state which continued autolight control. For example, when the mobile terminal 200 is only slightly deviated from the terminal installation unit 112, there is no problem even if the autolight control is continued, but there may be a case where the timing of turning on / off the headlight 130 or the like is deviated. In this case, the mobile terminal 200 or the vehicle 100 can warn the user by voice and notify that the position of the mobile terminal 200 has shifted. The vehicle 100 can also warn by displaying that the installation state is inappropriate on a display unit such as a navigation device.

<Configuration of Second Embodiment>
The auto light control system 20 of the second embodiment is a system that determines the installation state with the mobile terminal 200a, generates a light control signal with the vehicle 100a, and controls the headlight 130 and the like of the vehicle 100a to be turned on and off.

  In this case, the vehicle 100a includes a light switch 142 that can select an automatic light control function (FIG. 4). The light switch 142 has a function of turning on and off the headlight 130 and the like based on a user operation. The light switch 142 has a function of selecting auto light control for automatically turning on and off the headlight 130 and the like (see the position of “AUTO” in FIG. 4).

  FIG. 5 is a block diagram of the vehicle 100a and the mobile terminal 200a that constitute the auto light control system 20 of the second embodiment. Components having the same functions as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The vehicle 100a includes a light switch 142 that can select an automatic light control function and an illuminance sensor 144 for automatic light control by the vehicle 100a. The control unit 120a of the vehicle 100a includes a light control unit 150 and a light control signal generation unit 152. The light control signal generation unit 152 is a unit that generates a light control signal for controlling turning on and off of the headlight 130 and the like of the vehicle 100a based on the illuminance around the vehicle detected by the illuminance sensor 204 or 144. Other configurations of the vehicle 100a are the same as the vehicle 100 of the first embodiment.

  The control unit 202a of the mobile terminal 200a includes an installation state determination unit 224, a connection state detection unit 228, a signal strength detection unit 230, and a charge state detection unit 232. Unlike the portable terminal 200 of the first embodiment, the portable terminal 200a does not have the light control signal generation unit 226. Other configurations of the mobile terminal 200a are the same as those of the mobile terminal 200 of the first embodiment.

<Operation of Second Embodiment>
FIG. 6 is an operation flowchart of the auto light control system 20 of the second embodiment.

  Steps S21 and S22 are processed in the same manner as steps S1 and S2 of the first embodiment. That is, the user selects auto light control with the mobile terminal 200a (step S21), performs initial settings for auto light control (step S22), and then installs the mobile terminal 200a in the terminal installation unit 112. In this initial setting, the signal level of the illuminance detected by the illuminance sensor 204, that is, the gain of the illuminance sensor 204 is adjusted. In the vehicle 100a having the auto light control function, a threshold for the light control signal generation unit 152 to determine whether the headlight 130 or the like is turned on / off is set in advance. The gain of the illuminance sensor 204 is adjusted based on this threshold value.

  Steps S23 to S27 are processed in the same manner as steps S3 to S7 of the first embodiment. That is, the control unit 202a transmits a vehicle state information request signal to the vehicle 100a (step S23). When the light switch 142 is not operated by the user (NO in step S24), the control unit 120a receives the vehicle state information request signal transmitted from the mobile terminal 200a (YES in step S25) and is mounted on the vehicle 100a. Vehicle state information is acquired from each sensor and transmitted to the mobile terminal 200a (step S26). If the autolight control release signal has not been received (NO at step S27), the control unit 120a waits for illuminance data for generating a light control signal (NO at step S28).

  When receiving the vehicle state information, the control unit 202a acquires the terminal state information from each sensor and each detection unit mounted on the portable terminal 200a. The installation state determination unit 224 determines the installation state of the mobile terminal 200a with respect to the terminal installation unit 112 based on at least one of the vehicle state information and the terminal state information (step S29). The vehicle state information and the terminal state information are the same as those in the first embodiment. The determination is performed in the same manner as in the first embodiment.

  If the installation state determination unit 224 determines that the mobile terminal 200a is installed in the terminal installation unit 112 in an appropriate state (step S29 OK), the installation state determination unit 224 acquires illuminance data with adjusted gain from the illuminance sensor 204, and the vehicle 100a (Step S30).

  When the illuminance data is received from the mobile terminal 200a (YES in step S28), the light control signal generation unit 152 compares the threshold value preset in the vehicle 100a with the received illuminance data, and determines whether the headlight 130 or the like is on / off. (Step S31). The light control signal generation unit 152 generates a light control signal that controls turning on and off the headlight 130 and the like based on the on / off determination result (step S32).

  Steps S33 to S35 are processed in the same manner as steps S13 to S15 of the first embodiment. That is, the light control unit 150 controls the headlight 130 and the like to be turned on / off according to the generated light control signal (steps S33 to S35).

  The installation state determination unit 224 determines the installation state of the mobile terminal 200a every predetermined time (step S29) until the automatic light control is canceled by the user (YES in step S36). When it is determined that the mobile terminal 200a is installed in the terminal installation unit 112 in an appropriate state (step S29 OK), the control unit 202a repeats lighting / extinguishing control of the headlight 130 and the like of the vehicle 100a (step S30). ~ S36 NO).

  In this case, the signal level of the illuminance data is adjusted according to the gain set by the user in the mobile terminal 200a. Therefore, the light control unit 150 can turn on and off the headlight 130 and the like with a desired illuminance without changing the threshold value of the vehicle 100a. Further, the auto light control system 20 can be configured at low cost by using the light control signal generation unit 152 provided in advance in the vehicle 100a as an auto light control function.

  Steps S29, S37, S38, S27, and S24 are processed in the same manner as S9, S17, S18, S7, and S4 of the first embodiment. That is, if the installation state determination unit 224 determines that the mobile terminal 200a is not installed in an appropriate state in the terminal installation unit 112 (step S29 NG), the installation state determination unit 224 does not transmit the illuminance data to the vehicle 100a. The installation state determination unit 224 cancels the auto light control by the mobile terminal 200a (step S37), and transmits a cancel signal to the vehicle 100a (step S38). When the user cancels the auto light control by the portable terminal 200a (YES in step S36), the control unit 202a transmits a cancel signal to the vehicle 100a (step S38).

  When the control unit 120a receives the release signal from the installation state determination unit 224 (YES in step S27), the control unit 120a stops the process of transmitting the vehicle state information to the portable terminal 200a and enters a state of waiting for the user to operate the light switch 142 ( Step S24). In this case, illuminance data is not transmitted from the mobile terminal 200a to the vehicle 100a. Therefore, the headlight 130 and the like are not controlled to be turned on / off by inappropriate illuminance data.

  When the user operates the light switch 142 (YES in step S24), the light control unit 150 controls the headlight 130 and the like to be turned on / off according to the operation of the light switch 142. For example, it is assumed that the user operates the light switch 142 and selects the automatic light control by the vehicle 100a (YES in step S39). When the automatic light control by the vehicle 100a is selected, the light control signal generation unit 152 acquires illuminance data from the illuminance sensor 144 of the vehicle 100a, compares it with a predetermined threshold value, and generates a light control signal (step S40). . Next, the light control unit 150 controls the headlight 130 and the like to be turned on / off according to the light control signal (steps S33 to S35). In addition, it is assumed that the user operates the light switch 142 (YES in step S24) and selects manual light control (NO in step S39). In this case, the light control unit 150 controls the headlight 130 and the like to be turned on / off according to the operation of the light switch 142 (steps S41, S34, and S35).

  If the installation state determination unit 224 determines that the mobile terminal 200a is not installed in an appropriate state in the terminal installation unit 112 (step S29 NG), the auto light by the mobile terminal 200a is the same as in the first embodiment. You may perform the process for warning with respect to a user in the state which continued control. In this case, the user can switch to automatic light control by the vehicle 100a based on the warning.

  In addition, when the installation state determination unit 224 determines that the mobile terminal 200a is not installed in the terminal installation unit 112 in an appropriate state (step S29 NG), the installation state determination unit 224 performs processing for warning and also performs auto light by the vehicle 100a. It is also possible to automatically switch to the control and continue the auto light control. For example, when the mobile terminal 200a falls from the terminal installation unit 112, the user may not be aware that the automatic light control by the mobile terminal 200a is released. In such a case, the autolight control system 20 automatically continues the autolight control based on the autolight control function provided in the vehicle 100a, for example, so that the illuminance around the vehicle 100a has become a predetermined value or less. In this case, the headlight 130 and the like are turned on by the auto light control function of the vehicle 100a.

<Configuration of Third Embodiment>
The auto light control system 30 according to the third embodiment is a system that determines the installation state with the vehicle 100b, generates a light control signal with the mobile terminal 200b, and controls the lights of the vehicle 100b to be turned on and off.

  FIG. 7 is a block diagram of the vehicle 100b and the portable terminal 200b that constitute the auto light control system 30 of the third embodiment. Components having the same functions as those of the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The control unit 120b of the vehicle 100b includes a light control unit 150, a light control signal generation unit 152, an installation state determination unit 154, a connection state detection unit 156, a signal strength detection unit 158, and a charge state detection unit 160. Other configurations of the vehicle 100b are the same as those of the vehicle 100a of the second embodiment.

  The control unit 202b of the portable terminal 200b includes a light control signal generation unit 226. Unlike the second embodiment, the control unit 202b does not include the installation state determination unit 224, the connection state detection unit 228, the signal strength detection unit 230, and the charge state detection unit 232. Other configurations of the mobile terminal 200b are the same as those of the mobile terminal 200a of the second embodiment.

<Operation of Third Embodiment>
FIG. 8 is an operation flowchart of the auto light control system 30 of the third embodiment.

  Steps S51 and S52 are processed in the same manner as steps S1 and S2 of the first embodiment. That is, the user selects auto light control with the mobile terminal 200b (step S51), performs initial settings for auto light control (step S52), and then installs the mobile terminal 200b in the terminal installation unit 112. In this initial setting, the illuminance threshold is set as in the first embodiment.

  Next, the control part 202b acquires terminal state information, and transmits to the vehicle 100b (step S53).

  The terminal state information transmitted to the vehicle 100b includes, for example, the position of the mobile terminal 200b detected by the GPS receiver 214, the acceleration detected by the acceleration sensor 216, the angular velocity detected by the gyro sensor 218, or the proximity sensor 220. This is a detection result of an object close to the mobile terminal 200b detected by the above.

  When the light switch 142 is not operated by the user (NO in step S54), when the control unit 120b receives the terminal state information (YES in step S55), the vehicle state is detected from each sensor and each detection unit mounted on the vehicle 100b. Get information. The installation state determination unit 154 determines the installation state of the mobile terminal 200b in the terminal installation unit 112 based on at least one of the terminal state information and the vehicle state information, and transmits the determination result to the mobile terminal 200b (step S56). The determination is performed in the same manner as in the first embodiment and the second embodiment.

  The vehicle state information includes, for example, the position of the terminal installation unit 112 detected by the GPS receiver 134, the acceleration calculated from the speed detected by the speed sensor 136, the acceleration detected by the acceleration sensor 138, and the gyro sensor 140. The detected angular velocity, the connection state between the wired communication unit 122 and the wired communication unit 206 detected by the connection state detection unit 156, the signal strength of the signal received by the wireless communication unit 124 detected by the signal strength detection unit 158, or The charging state of the battery 212 on the portable terminal 200b side by the non-contact charging circuit 126 detected by the charging state detection unit 160.

  When the installation state determination unit 154 transmits the determination result to the mobile terminal 200b, the installation state determination unit 154 determines that the mobile terminal 200b is installed in an appropriate state in the terminal installation unit 112 (step S57 OK). ), The controller 120b waits for a write control signal (NO in step S58). In addition, when the installation state determination unit 154 determines that the mobile terminal 200b is not installed in an appropriate state in the terminal installation unit 112 (step S57 NG), the control unit 120b waits for the user to operate the light switch 142. A state is reached (step S54).

  Steps S59 to S62, S58, and S63 to S66 are processed in the same manner as steps S9 to S12, S8, and S13 to S16 of the first embodiment. That is, when the control unit 202b receives a determination result indicating that the mobile terminal 200b is installed in the terminal installation unit 112 in an appropriate state (step S59 OK), the control unit 202b sends the light control signal generation to the light control signal generation unit 226. Instruct. The light control signal generation unit 226 acquires illuminance data detected by the illuminance sensor 204 (step S60). The light control signal generation unit 226 compares the threshold set in step S52 with the acquired illuminance data, and determines whether the headlight 130 or the like is on or off (step S61). The light control signal generation unit 226 generates a light control signal based on the on / off determination result, and transmits the light control signal to the vehicle 100b (step S62).

  When the light control unit 150 receives the light control signal (YES in step S58), the light control unit 150 controls turning on and off the headlight 130 of the vehicle 100b in accordance with the light control signal (steps S63 to S65).

  The installation state determination unit 154 determines the installation state of the portable terminal 200b every predetermined time (step S56) until the automatic light control is canceled by the user (YES in step S66). When the control unit 202b receives a determination result indicating that the mobile terminal 200b is installed in the terminal installation unit 112 in an appropriate state (step S59 OK), the control unit 202b repeats the control of turning on and off the headlight 130 and the like of the vehicle 100b ( Steps S60 to S66 NO).

  On the other hand, when the control unit 202b receives a determination result that the mobile terminal 200b is not installed in the terminal installation unit 112 in an appropriate state (step S59 NG), the control unit 202b generates a light control signal for the light control signal generation unit 226. Do not instruct. The control unit 202b cancels the auto light control by the mobile terminal 200b (step S67). In this case, since the light control signal is not transmitted from the portable terminal 200b to the vehicle 100b, the headlight 130 and the like are not controlled to be turned on / off by an inappropriate light control signal.

  When the user cancels the auto light control by the mobile terminal 200b (YES in step S66), the control unit 202b transmits a cancel signal to the vehicle 100b (step S68). When receiving the release signal, the control unit 120b waits for the user to operate the light switch 142 (step S54).

  Steps S54, S69 to S71, and S63 to S65 are processed in the same manner as steps S24, S39 to S41, and S33 to S35 of the second embodiment. That is, assume that the user operates the light switch 142 and selects the automatic light control by the vehicle 100b (YES in step S69). The light control signal generation unit 152 compares the illuminance data detected by the illuminance sensor 144 of the vehicle 100b with a predetermined threshold value, and generates a light control signal (step S70). Next, the light control unit 150 controls the headlight 130 and the like to be turned on / off according to the light control signal (steps S63 to S65). Further, it is assumed that the user operates the light switch 142 (step S54 YES) and selects manual light control by the vehicle 100b (NO in step S69). In this case, the light control unit 150 controls the headlight 130 and the like to be turned on / off according to the operation of the light switch 142 (steps S71, S64, S65).
