Description

  The present invention relates to a vehicle charge reservation system that allows a user to specify a charge execution time reservation for a battery serving as a power source for a traveling motor.

  In recent years, as countermeasures for environmental and energy problems, electric vehicles equipped with a traveling motor driven by a battery (secondary battery) as a power source and so-called plug-in type hybrid vehicles (collectively referred to as electric vehicles) have been widely used. ing. These electric vehicles are capable of charging batteries at home using a household power source as well as charging batteries at charging stations equipped with charging facilities, parking lots, and the like. In addition, when a battery is charged at home using a home power supply, it is also possible to make a charge reservation by the user so that the user can charge using midnight power with a low power charge (for example, Patent Documents). 1 and 2).

  In this case, when the user operates the operation switch of the input unit provided in the vehicle and reserves and designates the charge start time, the time is set in the timer control unit. The timer control unit is configured to give an instruction to perform charging to the power control unit when the current time reaches the charge start time designated by the user. At this time, the charging start time that can be reserved by the user is limited to, for example, 24 hours after the current time because of the relationship between the data format and the memory capacity in the vehicle.

  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 the system is such that the battery can be reserved 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, it will be more convenient for the user. Can be increased. In constructing such a charge reservation system, it is desirable to minimize or minimize the change in the charge control device mounted in the vehicle, the in-vehicle LAN, and the like.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle charge reservation system that enables a user to make a charge reservation from the outside of the vehicle when charging a battery serving as a power source for a vehicle driving motor. In offer.

  In order to achieve the above object, a vehicle charge reservation system according to the present invention includes a charge control device that controls charging of a battery based on a reservation designation operation of a charge execution time of a battery serving as a power source for a driving motor by a user. A charging reservation system for a vehicle comprising: a communication device that is connected to an in-vehicle LAN and communicates with the outside by wireless communication; an information center that can communicate with the communication device; and the information center connected via a network And a communication terminal device configured to allow a user to perform a reservation designation operation of the charging execution time of the battery and to transmit the reservation designation data to the information center, and the charge control device includes a charge reservation for the battery It is configured to enable only the latest charge reservation data when receiving another charge reservation data during The information center includes an external reservation means for transmitting charge reservation data to the charge control device via the communication device based on receiving reservation designation data from the communication terminal device, and the communication terminal device. If the charge execution time specified for reservation exceeds the timer settable time of the charge control device, the charge reservation data that can be set for the timer is set so that the charge reservation is finally made at the time specified for reservation. And a reserved data division transmission means for transmitting a plurality of times in a form in which the designated time is sequentially extended (invention of claim 1).

  According to the above configuration, in addition to the user making a charge reservation by operating an operation input device in the vehicle such as a meter or a vehicle-mounted display, the user performs a reservation designation operation for the battery charge execution time on the communication terminal device. Thus, reservation designation data is transmitted to the information center via the network, and charge reservation data is further transmitted to the vehicle communication device by the external reservation means of the information center, and the charge reservation data is controlled to be charged via the in-vehicle LAN. Sent to the device. Therefore, the user can make a battery charging reservation by operating the communication terminal device from outside (remotely).

  When another charge reservation data is received during the charge reservation for the battery, only the latest charge reservation data is validated, so that the charge reservation is made by operating the operation input device in the vehicle. There is no conflict between the received data and the received charge reservation data.

  At this time, in the vehicle, a communication device capable of communicating with the information center is added while being connected to the in-vehicle LAN, so that the in-vehicle LAN and the charging control device are not changed or the change is minimized. However, a charge reservation system can be realized. The communication terminal device and the information center can be connected via the Internet or the like. In addition, as the communication device described above, an in-vehicle high-speed communication module called DCM (Data Communication Module) that performs communication using telematics can be employed.

  By the way, due to the relationship between the data format and the memory capacity in the vehicle, in general, the charging start time that can be reserved by the user, that is, the timer setting time of the charging control device, is limited, for example, within 24 hours. In the above configuration, since the reservation data division transmission means is provided in the information center, when the user performs a reservation designation operation for the battery charging execution time in the communication terminal device, the setting time of the charging control device is exceeded. Even if the reserved time is reserved, the reservation data division transmission means allows the timer-settable charge reservation data to be transmitted multiple times in the form of sequentially extending the specified time, and finally the user's reservation Charging can be performed at a specified time. That is, in the case of reservation designation using a communication terminal device, it is possible to substantially eliminate the restriction on the time that can be designated for reservation.

  In the charging reservation system for a vehicle according to the present invention, the charging control device performs another charging reservation data from the operation input device during the charging reservation in which a timer is set based on the charging reservation data from the information center. May be configured to transmit a signal indicating that the charge reservation has been canceled via the communication device to the information center (invention of claim 2).

  According to this, when the user performs another charge reservation operation using the operation input device in the vehicle during the charge reservation in which the reservation execution operation of the battery charge execution time is performed in the communication terminal device In the charge control device, only the latest charge reservation data is validated, and at the same time, a charge reservation cancel signal is transmitted to the information center. Therefore, in the information center, when charging reservation data is transmitted by the reservation data division transmission means, transmission of further charging reservation data can be stopped, and after the other charging reservation, from the information center. It is possible to prevent the occurrence of a problem that the transmission of the charge reservation data is continued.

  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. The vehicle charging reservation system 1 is possessed by a vehicle 2 such as an electric vehicle or a so-called plug-in hybrid vehicle (hereinafter referred to as “electric vehicle 2” for convenience), an information center 3, and a user of the electric vehicle 2, for example. The communication terminal device 4 is included.

  Here, although detailed illustration and description are omitted, the electric 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 electric vehicle 2 is provided with a charge monitoring ECU 6 as a charge control device. As will be described later, the charge monitoring ECU 6 is configured to control the charging of the battery 5, and always detects the remaining capacity (SOC) by monitoring the output voltage and output current of the battery 5, For example, it is configured to display in a predetermined column of the meter unit.

  At this time, the charging port 7 which has a charging connector is provided in the side wall etc. of the body of the electric 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 electric vehicle 2 can charge the battery 5 at home, The battery 5 can be charged by an external charging facility.

  The electric 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 monitoring 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 by the user, the operation input device 11 transmits a charge start or charge end signal to the charge monitoring ECU 6 via the in-vehicle LAN 10. The charge monitoring ECU 6 starts (ends) charging the battery 5 when receiving the charge start and end signals.

  In this embodiment, when the user operates the operation input device 11, reservation designation (charge reservation) of the charge execution time of the battery 5 can be performed. The operation for specifying the charge execution time reservation is performed, for example, by specifying the charge start time with respect to the current time displayed by the clock function in the vehicle. 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 monitoring ECU 6 via the in-vehicle LAN 10. This charge reservation data is data for giving an instruction to start charging, for example, how many minutes after the current time.

  When the charge monitoring ECU 6 receives the charge reservation data, the charge monitoring ECU 6 sets a timer for the time (in minutes) until the charge start specified in the data, and starts the timer count. When the counting of the time is completed, charging of the battery 5 is started. At this time, the time for which the charge monitoring ECU 6 can set the timer is limited to, for example, within 24 hours from the current time, that is, a maximum of 1440 minutes. Further, when the charge monitoring ECU 6 receives a plurality of charge reservation data, that is, when another charge reservation data is received during charge reservation (during timer counting), only the latest data is validated, that is, the previous data The data is invalidated and a new timer count is started.

  As shown in FIG. 1, the electric 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. Yes. In this case, the DCM 12 communicates (telematics communication) with the information center 3 through, for example, a mobile phone carrier (communication network) 13, and the electric vehicle 2 receives various information and services provided by the telematics service. It can be received. 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 electric 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 electric vehicle 2, and the reservation specification data via the network 14. 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 (month, date, hour, and minute). In the example, there is no restriction on the charging execution time that the user can specify for reservation, and reservation can be freely specified even at a time after 24 hours from the current time.

  Then, as will be described in the following description of the operation, 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 now) to the mobile phone carrier 13 To the corresponding electric vehicle 2 (DCM 12). The charge reservation data received by the DCM 12 is transmitted to the charge monitoring ECU 6 via the in-vehicle LAN 10. Similarly to the above, when the charge monitoring ECU 6 receives the charge reservation data, the charge monitoring ECU 6 sets a timer based on the charge reservation data and starts the timer count. When the time count is completed, the charge monitoring ECU 6 starts charging the battery 5. .

  At this time, if the charge execution time designated by the communication terminal device 4 exceeds the timer settable time (within 24 hours) of the charge monitoring ECU 6, the information center 3 is finally designated as reserved. In order to make a charge reservation at a time, charge reservation data that can be set by a timer is transmitted a plurality of times in the form of sequentially extending the designated time. Therefore, the information center 3 functions as an external reservation unit and includes a function of a reservation data division transmission unit.

  Specifically, as will be described in the following description of the operation, when the charge execution time designated for reservation exceeds 24 hours later (for example, after T minutes), first, 24 hours later (1440 minutes). After) charge reservation data is transmitted. The remaining time obtained by subtracting 1200 minutes from the reservation-designated time (for example, at the time after 1200 minutes (20 hours) has elapsed since the first reservation time) until the timer count in the charge monitoring ECU 6 ends (for example, T-1200 minutes), the next charging reservation data is transmitted. In this case, if T-1200 minutes still exceeds 24 hours, the division is repeated so that charging reservation data after 1440 minutes is transmitted again at that time.

  In the present embodiment, the charge monitoring ECU 6 receives another charge reservation data from the operation input device 11 during the charge reservation in which the timer is set based on the charge reservation data from the information center 3. Transmits a cancel signal indicating that the charge reservation has been canceled to the information center 3 via the DCM 12. When the information center 3 receives the cancel signal from the electric vehicle 2, the information center 3 cancels the designation of the charge reservation that has been received, and cancels the transmission of the charge reservation data scheduled thereafter.

  Next, the operation of the vehicle charging reservation system 1 configured as described above will be described with reference to FIGS. The sequence diagrams of FIGS. 2 to 5 show data related to the charge reservation of the battery 5 among the communication terminal device 4, the information center 3, the DCM 12 of the electric vehicle 2, the operation input device (HMI) 11, and the charge monitoring ECU 6. A specific example of the flow of transmission / reception is shown, and four different patterns (cases) are illustrated. Hereinafter, these sequence diagrams will be described in order.

  First, the sequence diagram of FIG. 2 shows that the user operates the communication terminal device 4 at, for example, 1:00 on January 1st, and the battery is set to charge execution (start) time on, for example, January 1st The case where 5 reservation designation | designated operation was performed is illustrated. When the reservation designation data (11:00 on January 1) is transmitted from the communication terminal device 4 to the information center 3, the information center 3 starts charging after 660 minutes from the charging reservation data, that is, the present time. Is transmitted to the corresponding electric vehicle 2 (DCM 12).

  In the electric vehicle 2, the charge reservation data (charge reservation after 660 minutes) received by the DCM 12 is transmitted to the charge monitoring ECU 6 via the in-vehicle LAN 10. When the charge monitoring ECU 6 receives the charge reservation data, the timer 660 is set. Set after minutes and start timer counting. Then, the charge monitoring ECU 6 starts charging the battery 5 when the tie mount for 660 is completed. Thus, the charging operation is started at the time when the user operates the communication terminal device 4 to make a reservation.

  Next, the sequence diagram of FIG. 3 shows that the user operates the communication terminal device 4 at, for example, 1:00 on January 1 and temporarily executes charging (starts at 11:00 on January 1, for example). ) Although the reservation designation operation for the battery 5 was performed as the time, the mind changed after that, for example, at 10:00 on January 1st, for example, 13:00 on January 1st by the operation input device 11 in the vehicle. The case where the reservation designation | designated operation of the battery 5 is performed as charging execution (start) time is illustrated.

  Also in this case, the reservation designation data (11:00 on January 1) is transmitted from the communication terminal device 4 to the information center 3, and the information center 3 instructs charging to start charging after 660 minutes from now. The reservation data is transmitted to the electric vehicle 2 (DCM 12). In the electric vehicle 2, the charge reservation data (charge reservation after 660 minutes) received by the DCM 12 is transmitted to the charge monitoring ECU 6 via the in-vehicle LAN 10, and the charge monitoring ECU 6 sets a timer after 660 minutes and sets the timer count. Start.

  The user operates the operation input device 11 at 10:00 on January 1 while the timer is being counted (charge reservation is in progress), and 13:00 on January 1 is set as the charge execution (start) time. When the reservation designation operation for the battery 5 is performed, charge reservation data for instructing to start charging 180 minutes after the present is transmitted from the operation input device 11 to the charge monitoring ECU 6. At this time, the charge monitoring ECU 6 validates the latest charge reservation data (the previous charge reservation data is invalidated), sets a timer 180 minutes after that time, and starts counting for 180 minutes.

  At this time, when charge reservation data is transmitted from the operation input device 11 to the in-vehicle LAN 10 at 10:00 on January 1, the DCM 12 receives the charge reservation data and sets another charge reservation data. A cancel signal to the effect is transmitted to the information center 3. The charge monitoring ECU 6 starts charging the battery 5 when the 180-minute timer count ends. Thus, the charging operation is started at the time (13:00 on January 1) when the user last specified the reservation based on the latest charging reservation data.

  In the sequence diagram of FIG. 4, for example, the user operates the communication terminal device 4 at 0:00 on January 1, and the battery 5 is set to have the charging execution (start) time of 3:00 on January 2, for example. The case where reservation designation | designated operation is performed is illustrated. In this example, it takes 27 hours from when the reservation designation operation is performed to when charging is started, which means that the time that can be set by the charge monitoring ECU 6 (24 hours) is exceeded.

  In this case, since the charge monitoring ECU 6 cannot set the timer (charge reservation) after 27 hours, the reservation designation data (3:00 on January 2) is transmitted from the communication terminal device 4 to the information center 3. In the information center 3, first, for example, charge reservation data instructing to start charging 1440 minutes after the current time (24 hours after the maximum time that can be set by the timer) is sent to the DCM 12 of the corresponding electric vehicle 2 Send to. In the electric vehicle 2, the charge reservation data (charge reservation after 1440 minutes) received by the DCM 12 is transmitted to the charge monitoring ECU 6 via the in-vehicle LAN 10, and the charge monitoring ECU 6 sets the timer after 1440 minutes and sets the timer count. To start.

  Then, in the information center 3, until the timer count in the charge monitoring ECU 6 ends, for example, at the time after 1200 minutes (20 hours) from the first reservation time, the remaining time after subtracting 1200 minutes from the reservation specified time , That is, 420 minutes (7 hours), the next charging reservation data instructing to start charging 420 minutes after the present is transmitted to the DCM 12. Then, the charge reservation data (charge reservation after 420 minutes) received by the DCM 12 is transmitted to the charge monitoring ECU 6 via the in-vehicle LAN 10.

  At this time, the charge monitoring ECU 6 also validates the latest charge reservation data, sets a timer 420 minutes after that time (1200 minutes after the first reservation time), and starts counting for 420 minutes. The charge monitoring ECU 6 starts charging the battery 5 when the 420-minute timer count ends. Thus, the charging operation is started 1620 minutes after the first reservation time (27 hours later), that is, at the time designated by the user (3:00 on January 2).

  In the sequence diagram of FIG. 5, for example, the user operates the communication terminal device 4 at 0:00 on January 1, for example, and the charge execution (start) time is set to 3:00 on January 2 for example. Although the reservation designation operation of the battery 5 was performed, the mind changed after that, for example, at 10:00 on January 1st, the operation input device 11 in the vehicle performed charging at 13:00 on January 1st (for example) The case where the reservation designation operation of the battery 5 is performed as the start time is illustrated.

  Also in this case, reservation designation data (3:00 on January 2) is transmitted from the communication terminal device 4 to the information center 3, and the information center 3 instructs charging to start charging after 1440 minutes from now. The reservation data is transmitted to the electric vehicle 2 (DCM 12). In the electric vehicle 2, the charge reservation data (charge reservation after 1440 minutes) received by the DCM 12 is transmitted to the charge monitoring ECU 6 via the in-vehicle LAN 10, and the charge monitoring ECU 6 sets the timer after 144 minutes and sets the timer count. To start.

  The user operates the operation input device 11 at 10:00 on January 1 (600 minutes after the start of the timer count), which is during the timer count (reservation of charge), and at 13: When a reservation designation operation for the battery 5 is performed with 00 as the charge execution (start) time, charge reservation data for instructing charging to start 180 minutes after the present is transmitted from the operation input device 11 to the charge monitoring ECU 6. . At this time, the charge monitoring ECU 6 validates the latest charge reservation data (the previous charge reservation data (1440 minute count) is invalidated), sets a timer 180 minutes after that point, and counts the 180 minutes. Start.

  Further, when charge reservation data is transmitted from the operation input device 11 to the in-vehicle LAN 10 at 10:00 on January 1, the DCM 12 receives the charge reservation data, and another charge reservation data is set. A cancel signal to that effect is transmitted to the information center 3.

  Here, in the information center 3 (if there is no other charge reservation data), the time after 1200 minutes (20 hours) from the first reservation time (12:00 on January 1) ), The next charge reservation data for the remaining 420 minutes (7 hours) was scheduled to be transmitted to the DCM 12. However, in response to the cancel signal, transmission of subsequent charging reservation data is canceled. The charge monitoring ECU 6 starts charging the battery 5 when the 180-minute timer count ends. Thus, the charging operation is started at the time when the user last specified the reservation (13:00 on January 1).

  As described above, according to the vehicle charging reservation system 1 of the present embodiment, in addition to the user making a reservation for charging by operating the operation input device 11 in the electric vehicle 2, the user can connect a mobile phone, By operating the communication terminal device 4 such as a personal computer or a smartphone, it is possible to make a reservation designation for the charging execution time of the battery 5. At this time, in the electric 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, so that the in-vehicle LAN 10 and the charge monitoring ECU 6 are not changed (the change is minimized). However, a charge reservation system can be realized.

  Here, due to the relationship between the data format of the in-vehicle LAN 10 and the memory capacity of the charge monitoring ECU 6, there is a circumstance that the charge start time that can be reserved by the user, that is, the timer setting time of the charge monitoring ECU 6 is limited within 24 hours. . However, in the present embodiment, when the user performs a reservation specifying operation for the charge execution time of the battery 5 in the communication terminal device 4, even if the user has reserved a time that exceeds the time that can be set by the timer of the charge monitoring ECU 6, The information center 3 is configured to transmit charging reservation data that can be set by a timer over a plurality of times in the form of sequentially extending the designated time (reservation data division transmission means). Accordingly, the battery 5 can be finally charged at the time designated by the user for reservation, and as a result, in the case of reservation designation using the communication terminal device 4, the restriction on the time at which reservation can be designated can be substantially eliminated. did it.

  Furthermore, in the present embodiment, when the user performs another charge reservation operation using the operation input device 11 in the vehicle during the charge reservation of the battery 5 for which the reservation designation operation is performed in the communication terminal device 4. In the charge monitoring ECU 6, only the latest charge reservation data is validated and a charge reservation cancel signal is transmitted to the information center 3. Therefore, after the other charge reservation, the charge from the information center 3 is charged. It is possible to prevent the occurrence of a problem that the transmission of the reservation data is continued.

  In the above-described embodiment, the case where transmission of the charge reservation data from the information center 3 to the electric vehicle 2 (DCM 12) is divided into two times, but may be divided into three or more times. Of course. 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. The specific numerical values such as the time and time described in the above can also be appropriately changed and implemented within a range not departing from the gist, such as only an example.
