JP 2009-60728 A

  In the conventional electric vehicle described above, it is necessary for the user to specify the reservation for charging the battery by operating the input unit in the vehicle. However, if a system that allows the user to make a battery charge reservation from the outside (remotely) of the vehicle using a communication terminal device such as a mobile phone, a personal computer, a smartphone, etc. possessed by the user, the convenience for the user is improved. Can be increased.

Therefore, the present inventor provided a communication device for performing wireless communication with the information center in the vehicle,
We considered a vehicle charging reservation system in which communication terminal devices such as mobile phones and personal computers possessed by users can be connected to an information center via the Internet or the like. According to this system, when the user operates the communication terminal device to perform a reservation designation operation for the battery charging execution time and transmits the reservation designation data to the information center, the information center corresponds to the charge reservation data. It transmits to the charge control apparatus of a vehicle. On the vehicle side, when the user prepares for charging (connection of the charging cable) in advance, the charging control device sets a timer based on the charging reservation data and starts charging at the time specified for reservation. Can be made.

  By the way, in such a system, there is a situation where the vehicle is parked (charged) is outdoors. For example, during the charge execution or the charge reservation (timer counting), It is conceivable that abnormalities such as disconnection of the charging cable and power failure due to the inadvertent contact of the three parties may occur. When such an abnormality occurs, data indicating the occurrence of the abnormality is transmitted from the vehicle (charging control device) side to the information center, and a charging abnormality has occurred to the communication terminal device possessed by the user from the information center. For example, it is desirable to have a configuration in which the above is notified by e-mail or the like. However, for example, a power outage occurs in a certain area, so there is a possibility that all (a plurality of) vehicles charged in that area may communicate (access) to the information center all at once. It is expected to cause troubles such as communication abnormalities.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to enable a user to make a charge reservation from the outside of a vehicle when charging a battery serving as a power source of a vehicle driving motor. An object of the present invention is to provide a vehicular charging reservation system capable of preventing problems associated with concentration of communication with an information center when an abnormality occurs.

  To achieve the above object, a vehicle charging reservation system according to the present invention includes a vehicle including a charging control device and a communication device, an information center, and a communication terminal device possessed by a user of the vehicle, Transmits charging reservation data to the charging control device of the vehicle via the communication device based on receiving reservation designation data from the communication terminal device, and the charging control device transmits the charging reservation data. , The vehicle charging reservation system is configured to perform charging for the battery at a time designated for reservation by setting a timer, and the vehicle detects an abnormality in the charging system for the battery. Abnormality detection means and an abnormality reporter for transmitting charging abnormality occurrence data to the information center by the communication device when an abnormality is detected by the abnormality detection means And the information center includes notification means for notifying that a charging abnormality has occurred to a communication terminal device of a user of the vehicle when the charging abnormality occurrence data is received, and the abnormality reporting means. Is characterized in that charging abnormality occurrence data is transmitted to the information center after a delay time set for each vehicle has elapsed (invention of claim 1).

  According to the above configuration, when the user performs a reservation designation operation for the battery charging execution time on the communication terminal device, the reservation designation data is transmitted to the information center via the network, and further the vehicle communication from the information center. Charge reservation data is transmitted to the charge control device via the device. Therefore, the user can make a battery charging reservation by operating the communication terminal device from outside (remotely) the vehicle.

  When the abnormality detecting means detects that an abnormality has occurred in the charging system during the charging of the battery or during the charge reservation, the abnormality reporting means detects charging abnormality occurrence data to the information center via the communication device. Is sent. When the information center receives the charging abnormality occurrence data, the information center notifies the communication terminal device of the user of the vehicle that charging abnormality has occurred by the notification means.

  At this time, since an abnormality such as a power failure occurs in a certain area, if there are a plurality of vehicles that are charged (reserved for charging) in the area, an abnormality reporting means for each of the plurality of vehicles. Thus, the information center is notified of the occurrence of an abnormality. However, since the abnormality reporting means transmits the charging abnormality occurrence data to the information center after the delay time set for each vehicle has elapsed, it is possible to avoid the concentration of transmissions to the information center. It is possible to prevent troubles such as communication abnormality.

  As the communication terminal device, for example, a mobile phone, a personal computer, a smartphone or the like possessed by the user can be adopted. The communication terminal device and the information center can be connected via the Internet or the like. As a communication device provided in the vehicle, an in-vehicle high-speed communication module called DCM (Data Communication Module) that performs communication using telematics can be employed. An e-mail or the like can be used for the notification to the user's communication terminal device by the notification means.

  In the present invention, the abnormality reporting unit includes a retransmission unit that repeats transmission of charging abnormality occurrence data again after a predetermined waiting time has elapsed when communication failure occurs during transmission of charging abnormality occurrence data to the information center. In addition, the predetermined waiting time can be set for each vehicle (invention of claim 2).

  According to this, even if the communication of the charging abnormality occurrence data once by the abnormality reporting means is unsuccessful, the retransmission means repeatedly transmits the charging abnormality occurrence data after a predetermined waiting time has elapsed. The charging abnormality occurrence data can be reliably transmitted to the information center. Also in this case, since the predetermined waiting time is set for each vehicle, concentration of communication with the information center at the time of data transmission again can be avoided.

  In the present invention, the delay time described above is configured to be determined based on the current charge amount (remaining capacity) of the battery of the vehicle (invention of claim 3), or for each vehicle. It may be configured to determine based on the unique number assigned (invention of claim 4). According to these, it is possible to ensure the randomness when setting the delay time for each vehicle.

Time chart for explaining communication delay time when charging abnormality occurs

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 schematically shows the overall configuration of a vehicle charging reservation system 1 according to the present embodiment. This vehicle charging reservation system 1 includes an electric vehicle 2 (hereinafter simply referred to as “vehicle 2”) having at least an electric motor as a power source, such as an electric vehicle or a so-called plug-in hybrid vehicle, an information center 3, And a communication terminal device 4 possessed by a user of the vehicle 2.

  Although not shown or described in detail, the vehicle 2 includes a traveling motor that rotationally drives wheels and a battery 5 that serves as a power source for the traveling motor, as is well known. As this battery 5, a lithium ion secondary battery is employ | adopted, for example. The “battery” in the present invention is a concept including a capacitor that can be repeatedly charged and discharged.

  The vehicle 2 is provided with a charge management ECU 6 as a charge control device. As will be described later, the charge management ECU 6 is configured to control the charging of the battery 5, and an abnormality in the charging system during the execution of charging (or during charging reservation), for example, disconnection of a charging cable described later ( Connection abnormality) or power interruption due to a power failure of the commercial power supply, etc., and functions as an abnormality detection means. The charge management ECU 6 is configured to monitor the output voltage, output current, etc. of the battery 5 to constantly detect the remaining capacity (SOC) and display it in a predetermined column of the meter section, for example.

  At this time, the charging port 7 which has a charging connector is provided in the side wall etc. of the vehicle 2, for example. A charging facility 9 as an external power source is detachably connected to the charging port 7 (charging connector) via a charging cable 8. Examples of the charging facility 9 include a household power outlet, an external charging facility provided at a charging station, a parking lot, and the like. The user of the vehicle 2 can charge the battery 5 at home, The battery 5 can be charged with a charging facility.

  The vehicle 2 is provided with an in-vehicle LAN 10. The in-vehicle LAN 10 employs, for example, a bus type communication network system called CAN (Controller Area Network). Although not shown, a plurality of controls such as an engine ECU, a transmission ECU, a brake ECU, and a navigation ECU are provided. Units are connected to each other. The in-vehicle LAN 10 (CAN bus) is connected to the charge management ECU 6 and an operation input device 11 called an HMI (Human Machine Interface).

  Specifically, as the operation input device 11, for example, a display unit for a navigation device that is configured by incorporating a display, a touch panel, and various mechanical switches and provided in a center console portion is used. Alternatively, as the operation input device 11, an operation device provided on the meter unit or the steering wheel, an operation device provided on the driver's seat side portion, or the like may be employed. By operating the operation input device 11, the user can input various instructions regarding navigation and the like, and can also input instructions regarding charging of the battery 5.

  In this case, the user can operate the operation input device 11 to instruct execution (start) or stop (end) of the battery 5 in real time. When the operation input device 11 receives a charge start or end instruction input from the user, the operation input device 11 transmits a charge start or charge end signal to the charge management ECU 6 via the in-vehicle LAN 10. The charge management ECU 6 starts (ends) charging the battery 5 when receiving the charge start and end signals.

  Further, in this embodiment, when the user operates the operation input device 11, it is possible to perform reservation designation (charge reservation) for the charge execution time of the battery 5. The operation for specifying the reservation of the charging execution time is performed by specifying the charging start time for the current time displayed by the clock function in the vehicle, for example. Of course, it can be configured to specify an elapsed time such as to start charging after how many hours and minutes, or to specify an end time of charging.

  When the operation input device 11 accepts a reservation designation operation by the user, the operation input device 11 transmits charge reservation data to the charge management ECU 6 via the in-vehicle LAN 10. This charge reservation data is data for instructing how many minutes from the current time to start charging. When the charge management ECU 6 receives the charge reservation data, the charge management ECU 6 sets a timer at the time (after several minutes) until the start of charge specified in the data, and starts the timer count. When the counting of the time is completed, charging of the battery 5 is started.

  As shown in FIG. 1, the vehicle 2 is provided with a DCM (Data Communication Module) 12 as a communication device for performing wireless communication using telematics with the outside, connected to the in-vehicle LAN 10. . In this case, the DCM 12 performs communication (telematics communication) with the information center 3 via, for example, a mobile phone carrier (communication network) 13, and the vehicle 2 receives various information and services provided by the telematics service. Be able to. At this time, as will be described later, the charging reservation data transmitted from the information center 3 is received by the DCM 12.

  The communication terminal device 4 includes, for example, a mobile phone, a personal computer, a smart phone, and the like possessed by a user, and is connected to the information center 3 via a network 14 such as the Internet. The user of the vehicle 2 operates the communication terminal device 4 to specify the reservation for the charging execution time of the battery 5 from the outside (remote) of the vehicle 2, and stores the reservation specification data via the network 14. It can be transmitted to the information center 3. At this time, when making a charge reservation, the user operates the operation unit of the communication terminal device 4 to input, for example, a charge execution (start) time (what month, what hour, what minute).

  As will be described later in the description of the operation (flowchart description), when the information center 3 receives the reservation designation data from the communication terminal device 4, the information center 3 sends the charge reservation data (after a few minutes from the start of charging) to the mobile phone. It transmits toward the applicable vehicle 2 (DCM12) via the carrier 13. The charge reservation data received by the DCM 12 is transmitted to the charge management ECU 6 via the in-vehicle LAN 10. Similarly to the above, when the charge management ECU 6 receives the charge reservation data, the charge management ECU 6 sets a timer based on the charge reservation data and starts a timer count. When the count of the set time is completed, the charge management ECU 6 starts charging the battery 5. To do.

  Then, as described above, the charge management ECU 6 mainly monitors whether there is an abnormality in the power source such as a power interruption during the execution of the charge (and during the charge reservation). Abnormality occurrence data is transmitted to the information center 3. Therefore, an abnormality reporting means is constituted by the charge management ECU 6, the DCM 12, and the like. When the information center 3 receives the charging abnormality occurrence data from the vehicle 2 (DCM 12), a method in which the user specifies in advance that a charging abnormality has occurred with respect to the communication terminal device 4 possessed by the user of the corresponding vehicle 2, For example, notification is made by e-mail. Therefore, the information center 3 is configured to include the function of notification means.

  At this time, when the charging management ECU 6 (DCM 12) transmits charging abnormality occurrence data to the information center 3, the charging management ECU 6 (DCM 12) performs transmission after a delay time T1 set randomly for each vehicle 2 has elapsed. Yes. In this embodiment, the delay time T1 is determined based on the current charge amount (remaining capacity SOC) of the battery 5. More specifically, as shown in FIG. 5, the initial delay time T1 is a value obtained by multiplying the charge amount of the battery 5 of the vehicle 2 at the time of abnormality detection by the initial default value (for example, 60 seconds). Set to

  Further, in this embodiment, the charging management ECU 6 (and the DCM 12 or the like), when transmitting the charging abnormality occurrence data to the information center 3, if communication is not successful (cannot be transmitted), waits for a predetermined time. The transmission of the charging abnormality occurrence data is repeated (retryed) again after the elapse of time T2, and a function as a retransmission means is also provided. At this time, also for the predetermined waiting time, a different (random) value is set for each vehicle 2 based on the current charge amount (remaining capacity SOC) of the battery 5. More specifically, the delay time T2 at the time of retransmission is set to a value obtained by multiplying the charge amount of the battery 5 of the vehicle 2 at the time of abnormality detection by a default value for retransmission (for example, 300 seconds).

  Next, the operation of the vehicle charging reservation system 1 configured as described above will be described with reference to FIGS. The flowchart of FIG. 2 shows a procedure of processing related to the charging reservation of the battery 5 from the outside in the vehicle charging system 1 of the present embodiment. The flowchart of FIG. 3 shows a processing procedure for charging control of the reserved battery 5 in the vehicle charging system 1. Further, the flowchart of FIG. 4 shows a detailed processing procedure for transmitting (notifying) charging abnormality occurrence data from the DCM 12 to the information center 3 in step S17 of FIG. Hereinafter, these flowcharts will be described in order.

  First, in the flowchart of FIG. 2, when the user makes a reservation for charging the battery 5 of the vehicle 2 from the outside, the user wants to execute (start) charging by operating the communication terminal device 4 in step S1. The time, for example, what month and what day (or how many hours and minutes after the current time) is input. In the next step S <b> 2, the reservation designation data (what month and what time) is transmitted from the communication terminal device 4 to the information center 3. Then, in step S3, charging reservation data, that is, data instructing how many minutes after the current charging is started is transmitted from the information center 3 to the corresponding vehicle 2 (DCM 12).

  Then, in step S4, the charge reservation data (the charge reservation after several minutes) received by the DCM 12 in the vehicle 2 is transmitted to the charge management ECU 6 via the in-vehicle LAN 10, and the charge management ECU 6 performs a timer based on the charge reservation data. To start timer count. This completes the charge reservation from the outside. In this case, for example, when the user makes a reservation for charging at midnight, the battery 2 can be charged using cheap midnight power without being present at the time of charging. In addition, when making a reservation, it is a matter of course that the user performs preparatory work necessary for charging such as connection of the charging cable 8 in advance.

  Next, in the flowchart of FIG. 3, in step S11, the charge management ECU 6 always determines whether or not the reserved time has come, and when the tie-mount of the set timer time ends (Yes in step S11), step S12. Start charging at. Thus, the charging operation is started at the time when the user makes a reservation by operating the communication terminal device 4. In step S13, the charge management ECU 6 constantly monitors whether the power supply during charging is normal (whether there is an abnormality). If there is no charging abnormality (Yes in step S13), it is determined in next step S14 whether or not the battery 5 is fully charged. If the battery is fully charged without any abnormality (Yes in step S14), the charging is terminated.

  On the other hand, during charging, an abnormality in power interruption may be detected due to, for example, disconnection of the charging cable 8 caused by wind and rain or inadvertent contact by a third party, occurrence of a power failure, etc. (step No at S13). In this case, first in step S15, the charge management ECU 6 stops the charging operation. In the next step S16, the charging management ECU 6 transmits charging abnormality occurrence data to the DCM 12, and in step S17, charging abnormality occurrence data is transmitted from the DCM 12 to the information center 3. Details of the charging abnormality occurrence data transmission processing in step S17 will be described in the description of FIGS.

  When the transmission of the charging abnormality occurrence data from the DCM 12 to the information center 3 is completed, in the next step S18, charging abnormality has occurred from the information center 3 to the communication terminal device 4 possessed by the user of the corresponding vehicle 2 ( The fact that the charging operation has been stopped) is notified by e-mail, for example, and the process ends. By this notification, the user can quickly know (for example, the next morning if sleeping at night) that an abnormality such as a power interruption has occurred, and can take necessary measures.

  Now, the process of transmitting charging abnormality occurrence data from the DCM 12 to the information center 3 in step S17 will be described in detail with reference to FIGS. That is, as shown in FIG. 4, first, in step S21, the communication connection from the DCM 12 to the information center 3 is not performed immediately, but is delayed by the delay time T1. As shown in FIG. 5, the delay time T1 at this time is obtained by multiplying the charge amount (remaining capacity SOC) of the battery 5 of the vehicle 2 at the time of abnormality detection by the initial default value (for example, 60 seconds). Is set. As an example, when the charge amount is 25%, T1 = 0.25 × 60 seconds and the delay time T1 is 15 seconds.

  After the delay time T1 has elapsed, in step S22, communication connection with the information center 3 is performed, and charging abnormality occurrence data is transmitted. In the next step S23, it is determined whether or not communication with the information center 3 has been correctly performed (whether there has been a response from the information center 3). If communication has been correctly performed (Yes in step S23), processing is performed. Ends. On the other hand, for example, when there is simultaneous access to the information center 3 from the DCMs 12 of the plurality of vehicles 2, there may be a case where the communication connection ends abnormally.

  Therefore, when the charging abnormality occurrence data is transmitted from the DCM 12 to the information center 3 and communication is not successful (No in step S23), the charging abnormality occurrence data may be transmitted again (retry). At that time, in step S24, the process waits for the elapse of a predetermined waiting time T2, and then repeats the retry (step S22). As shown in FIG. 5, the waiting time T2 at this time is set to a value obtained by multiplying the above-mentioned charged amount (remaining capacity SOC) of the battery 5 by a default value for retransmission (for example, 300 seconds). For example, in the case where the charge amount is 25%, T2 = 0.25 × 300 seconds and the waiting time T2 is 75 seconds.

  Here, when the above-mentioned charging abnormality is due to a power failure, it occurs in a certain area, so from the DCMs 12 of all (a plurality of) vehicles 2 charged in that area all at once. If charging abnormality occurrence data is transmitted to the information center 3, it is expected that communication concentrates and eventually causes troubles such as communication abnormality. However, in the present embodiment, the charging abnormality occurrence data is transmitted to the information center 3 after a delay time T1 set randomly for each vehicle 2 has elapsed, so that the transmission to the information center 3 is prevented from being concentrated. can do. Even during retransmission (retry), since the predetermined waiting time T2 is set randomly for each vehicle 2, concentration of communication with the information center 3 during retransmission can be avoided.

  As described above, according to the vehicle charging reservation system 1 of the present embodiment, the user operates the communication terminal device 4 such as a mobile phone, a personal computer, or a smartphone to specify the reservation for the charging execution time of the battery 5 from the outside. be able to. At this time, in the vehicle 2, the DCM 12 that can communicate with the information center 3 is added in a state of being connected to the in-vehicle LAN 10, whereby the vehicle charging reservation system 1 can be realized with a simple configuration.

  In this embodiment, when the charging management ECU 6 detects that an abnormality has occurred in the charging system while the battery 5 is being charged (or during charging reservation), the information center 3 is charged from the DCM 12. The abnormality occurrence data is transmitted, and the information center 3 is configured to notify the communication terminal device 4 of the user of the vehicle 2 that a charging abnormality has occurred. Thereby, it is possible to promptly notify the user that an abnormality such as a power shutdown has occurred.

  At this time, for example, an abnormality such as a power failure occurs in a certain region. Therefore, when there are a plurality of vehicles 2 that are charged (reserved for charging) in the region, the DCMs 12 of the plurality of vehicles 2 are used. There is a possibility that communication (access) to the information center 3 from will be concentrated. However, since communication with the information center 3 is performed after the delay time T1 set for each vehicle 2 has elapsed, it is possible to avoid concentration of communication with the information center 3, and as a result, communication abnormalities, etc. Problems can be prevented in advance.

  In particular, in this embodiment, even if communication of one charging abnormality occurrence data from the DCM 12 to the information center 3 is unsuccessful, a retry is performed after a predetermined waiting time T2 has elapsed. It is possible to reliably transmit to the information center 3. Also in this case, since the waiting time T2 is set for each vehicle 2, concentration of communication with the information center 3 at the time of data transmission again can be avoided. In this embodiment, since the delay time T1 and the waiting time T2 are determined based on the current charge amount of the battery 5 of the vehicle 2, the delay time is set for each vehicle 2. An advantage that randomness can be secured can also be obtained.

  In the above-described embodiment, the delay time T1 and the waiting time T2 are determined based on the charge amount of the battery 5 of the vehicle 2, but the unique number (manufacturing number or ID) assigned to each vehicle 2 is used. It can also be configured to make a determination based on this. More specifically, for example, the last digit of the vehicle ID is added to or subtracted from the default value to obtain the delay time, or the last two digits of the ID is used as the delay time (seconds). It can be determined by various methods such as a delay time obtained by adding the last digit of the ID to the value calculated based on the charge amount of the battery 5. Further, when the DCM 12 includes positioning means, the delay time T1 and the waiting time T2 may be determined by adding or subtracting latitude information and longitude information, for example, based on the position information acquired by the positioning means. good. This also ensures the randomness when setting the delay time and the waiting time for each vehicle 2 as in the above embodiment.

  Further, the delay time T1 and the waiting time T2 can be determined by different methods, or a numerical value obtained by adding or multiplying a predetermined value to the delay time T1 can be set as the waiting time T2. Further, when the retry is repeated twice or three times, the waiting time may be changed. In addition, the present invention can also be applied to a vehicle having a configuration in which a solar cell is provided, for example, on a roof portion or the like, and the generated power of the solar cell is used as part of the charging of the battery. Specific numerical values such as the time T1 and the waiting time T2 can also be appropriately changed and implemented within a range that does not depart from the gist, such as only an example.
