Moreover, you may add another step between each process step. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  As a premise, the in-vehicle device 3 stores reservation information received from the server 1 in a predetermined storage area. Further, S102 to S107 in FIG. 4 indicate power control processing at the start of vehicle use, and S108 to S111 indicate power control processing during vehicle use.

  The vehicle state determination unit 34 determines the state of the vehicle 5 by monitoring the vehicle rental signal input from the key storage device 7 (S100). And when there is no input of a vehicle rental signal, it judges that vehicle 5 is returning (S101; YES), and judges whether vehicle 5 shifts from a return state to a rental state (S102).

  Here, when the use start time comes, the user presents an IC card, a portable terminal, or the like with a built-in storage medium storing a member ID unique to the user in a reading device such as an IC card reader installed in the reserved vehicle. For example, the in-vehicle device 3 determines whether or not the member ID included in the reservation information matches the member ID read by the reading device, and the use start date and time and use end date and time included in the reservation information. And if both the determination results are right, it is determined that the authentication is successful. If the user authentication is successful, the door of the reserved vehicle is unlocked and can be used, so the user enters the vehicle and removes the key from the key storage device 7. When the key storage device 7 detects the removal of the key, the key storage device 7 sends a vehicle rental signal to the vehicle state determination unit 34.

  When the vehicle lending signal is input from the key storage device 7, the vehicle state determination unit 34 determines that the vehicle 5 has shifted to the lending state, and reports that fact to the car navigation control unit 33 (S102; YES).

  When a vehicle rental signal is input from the vehicle state determination unit 34, the car navigation control unit 33 sends a power activation signal for switching the power of the navigation device 4 to the on state to the navigation device 4 via the connection unit 37. (S103). When the power management unit 48 of the navigation device 4 receives the power activation signal, the power management unit 48 switches the power to the on state and starts supplying power from the battery 52 to each unit of the navigation device 4.

  When the navigation device 4 is turned on, the car navigation control unit 33 generates a use start information display instruction to display the car sharing use start information on the navigation device 4, and the navigation device via the connection unit 37. 4 (S104). The content of the usage start information can be determined as appropriate according to the design, and can include, for example, the usage start time and usage end time of the user. Further, the use start information may be displayed together on one screen, or may be displayed divided into a plurality of screens. Also, a usage start information voice output instruction for outputting the usage start information by voice may be generated and sent to the navigation device 4.

  When the navigation apparatus 4 receives the use start information display instruction, the navigation apparatus 4 displays a use start screen based on the use start information display instruction on the display (see FIG. 6A). FIG. 6A shows an example of the usage start screen 601. In addition, when the navigation apparatus 4 receives the usage start information voice output instruction, the navigation apparatus 4 outputs a voice based on the start information voice output instruction from the speaker.

  Next, the car navigation control unit 33 determines whether the accessory state of the ignition switch 51 is on or off based on the determination result of the ACC state determination unit 35 (S105). When the car navigation control unit 33 determines that the accessory state is turned on after a predetermined time (hereinafter referred to as “ACC designated time”) has elapsed after the power activation signal is sent (S106; YES), the use starts. The information display control process ends. For example, after the user removes the key from the key storage device 7, the user inserts the key into the ignition switch 51 of the vehicle 5 and operates it to the ACC position or the ON position within the ACC designated time. The ACC designation period can be arbitrarily set according to the specification and design, and is not particularly limited, but is set to 15 minutes in this embodiment.

  On the other hand, if the car navigation control unit 33 determines that the accessory state of the vehicle 5 has not been turned on before the ACC designated time has elapsed (S106; NO), a power stop signal is used to turn off the power of the navigation device 4. (S107). When a power stop signal is input, the power management unit 48 of the navigation device 4 switches the power to the off state.

  Next, returning to S <b> 101, the power supply control process during which the vehicle 5 is lent will be described. When the vehicle state determination unit 34 determines that the vehicle 5 is not being returned (S101; NO), the ACC state determination unit 35 determines the accessory state of the vehicle 5 based on whether or not an accessory signal is input (S108). . When the accessory signal is input, the ACC state determination unit 35 determines that the accessory is in the on state (S109; YES), and notifies the car navigation control unit 33 accordingly.

  Next, the car navigation control unit 33 determines the power state (ON / OFF) of the navigation device 4 (S110). The determination as to whether or not the power of the navigation device 4 is on is performed, for example, by performing a predetermined communication with the navigation device 4 and when there is no reply from the navigation device 4 within a predetermined time, the navigation device 4 can be determined not to be in an on state (that is, in an off state). For example, when the power supply information indicating the power supply state of the navigation device 4 is stored in a predetermined storage area, it may be determined by referring to this.

  When the car navigation control unit 33 determines that the navigation apparatus 4 is not turned on (S110; NO), the car navigation control unit 33 sends a power activation signal for turning on the navigation apparatus 4 to the navigation apparatus 4 (S111). ). When the navigation apparatus 4 receives the power activation signal, the navigation apparatus 4 switches the power to the on state. On the other hand, if it is determined that the power of the navigation device 4 is on (S110; YES), the process ends.

  According to the above, at the timing when the user removes the key of the reserved vehicle 5 from the predetermined key storage device (at the start of use of the vehicle), the power of the navigation device 4 is switched on, and the use start information is displayed in the navigation device 4. Is displayed and output. On the other hand, at a timing such as when the engine is turned off and then turned on again while the vehicle is being used, the navigation device 4 is simply turned on, and the usage start information is not displayed on the navigation device 4. Therefore, it becomes possible to provide the user with the use start information of car sharing at an appropriate timing, and for example, the use start information can be prevented from being redisplayed every time the engine is turned on again. It is possible to avoid giving annoyance.

  If the user removes the key of the reserved vehicle 5 from the key storage device 7 but does not switch on the engine within the accessory designated time, the navigation device 4 displays the usage start information and then outputs the navigation device 4. 4 is automatically turned off. Therefore, the battery 52 of the vehicle 5 can be saved.

In the present embodiment, the use end information display condition is that the vehicle 5 is located at the return place (return place condition) and / or that the vehicle 5 has shifted to the return state within the designated return time (return transition condition). However, the use end information display conditions are not limited to these, and can be set as appropriate according to the specification design.

  The ACC state determination unit 35 determines the accessory state based on whether or not the accessory signal is input from the ignition switch 51 (S201), and determines that the accessory state is switched from the on state to the off state (S201). YES), the fact is notified to the car navigation control unit 33.

  The car navigation control unit 33 measures the current position via the position positioning unit 38 (S202).

  The car navigation control unit 33 reads the coordinate information of the return location of the vehicle 5 from the predetermined storage area of the storage unit 36 (S203). In the present embodiment, the coordinate information of the return point of the vehicle 5 is stored in the storage unit 36 as reservation information. When a different return point can be specified for each reservation, the return place included in the reservation information related to the reservation authenticated by the user when using car sharing is specified.

  The car navigation control unit 33 determines whether or not the vehicle 5 is at the return location based on the current position measured via the position positioning unit 38 and the coordinate information of the return location read from the predetermined storage area ( S204). That is, the car navigation control unit 33 determines that the vehicle 5 is in the return place when the coordinate information of the measured current position and the coordinate information of the return place of the vehicle 5 substantially match. It is determined that the vehicle 5 is not in the return place.

  When the car navigation control unit 33 determines that the vehicle 5 is at the return place (S204; YES), after the accessory state is switched from on to off, a predetermined designated time (hereinafter referred to as “return designated time”). It is determined via the vehicle state determination unit 35 whether or not the vehicle state has shifted from return to lending before elapse of ().

  When the car navigation control unit 33 determines that the vehicle state has shifted from return to lending within the designated return time after the accessory state switches from on to off (S205; YES), the car sharing use end information Is generated and transmitted to the navigation device 4 (S206).

For example, if the car navigation control unit 33 determines in S102 of FIG. 4 that the vehicle 5 has shifted from the return state to the rental state, the car navigation control unit 33 measures the current position via the position positioning unit 38. Further, the car navigation control unit 33 reads out coordinate information of the rental location of the vehicle 5 from a predetermined storage area of the storage unit 36. The car navigation control unit 33 determines whether or not the vehicle 5 is at the rental location based on the measured current position and the coordinate information of the rental location read from the predetermined storage area. That is, the car navigation control unit 33 determines that the vehicle 5 is in the rental location when the coordinate information of the current position and the coordinate information of the rental location of the vehicle 5 substantially match. It is determined that the vehicle 5 is not at the rental location. When the car navigation control unit 33 determines that the vehicle 5 is at the rental location, the car navigation control unit 33 sends a power activation signal for switching the power of the navigation device 4 to the on state.
(3) Further, for example, a condition related to the reservation start time may be set in the use start information display condition, or a condition related to the reservation end time may be set in the use end information display condition. For example, if the car navigation control unit 33 determines in S102 of FIG. 4 that the vehicle 5 has shifted from the return state to the rental state, the current time is within a predetermined elapsed time from the reservation start time included in the reservation information. It is also possible to control so that the usage start information is displayed on the navigation device on the condition. In addition, when the car navigation control unit 33 determines in S201 of FIG. 5 that the accessory state has shifted from on to off, the current time is reserved information together with or instead of the return location condition and the return transition condition described above. The use end information may be controlled to be displayed on the navigation device on the condition that it is a predetermined time before the reservation end time included in.
