Details of the first embodiment will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating an example of a parking lot at a charging station. The charging station (charging place) includes a charging station facility and a parking lot for charging. The charging station facility includes a parking guidance device 1 and a vehicle detection device 4.

  FIG. 2 is a diagram illustrating an embodiment of the parking guide device 1, the vehicle 2, and the vehicle charging device 3. The parking guidance device 1 includes a receiving unit 5, a processing unit 6, a recording unit 7, and a communication unit 8. The parking guidance device 1 may be a personal computer (PC) or a server. In addition, the parking guidance device 1 is connected to the vehicle detection device 4 by wire or wireless. Furthermore, the parking guidance apparatus 1 may communicate with a server provided outside via the Internet or a dedicated line.

  The vehicle detection device 4 detects the vehicle 2 that has entered the parking lot and notifies the parking guidance device 1 of it. The vehicle detection device 4 is, for example, a camera or a video camera, acquires an image related to the vehicle 2 that has entered, and determines whether or not the vehicle has entered. Thereafter, the vehicle detection device 4 transmits information indicating that the vehicle 2 has entered the parking guidance device 1. The vehicle detection device 4 may be integrated with the vehicle charging device 3, and in this example, the vehicle charging device provided in the parking spaces No3, No5, and No6 in FIG. 1 that can monitor the entrance of the charging station. It is preferable to provide in 3a, 3b. Here, the vehicle charging device 3a is a vehicle charging device for rapid charging, and the vehicle charging device 3b is a vehicle charging device for normal charging. Further, the vehicle detection device 4 may not be a camera or a video camera. For example, the vehicle detection device 4 receives a signal output from the magnetic sensor 4a embedded in the ground as shown in FIG. It may be detected that the vehicle 2 has entered.

The receiving unit 5 acquires vehicle information indicating that the vehicle 2 transmitted from the vehicle detection device 4 has entered, and outputs the vehicle information to the processing unit 6.
When the processing unit 6 acquires the vehicle information indicating that the vehicle 2 has entered, the processing unit 6 communicates with the vehicle charging devices 3a and 3b in the parking lot and acquires the current vehicle charging device acquired from each of the vehicle charging devices 3a and 3b. Charging information described later is acquired from each of 3a and 3b. Next, the processing unit 6 detects a chargeable parking space using the charging information. The charging information includes, for example, information such as “parking position” and “usage status” as indicated by charging information 31 shown in FIG. FIG. 3 is a diagram illustrating an example of a data structure of charging information and charging facility information. “Parking position” is an identifier for identifying a parking space. In this example, “1” is recorded as an example of the parking space No1 shown in FIG. In the case of parking spaces No2 to No9, "2", "3", "9", etc. are recorded. “Usage status” indicates the current usage status of the vehicle charging device 3 and is an identifier indicating whether or not charging is in progress. For example, “use” is displayed when charging or parking, and “empty” is displayed when the vehicle 2 is not in the parking space. In the example of FIG. 1, parking spaces No 2 and No 7 are indicated as “use”, and parking spaces other than parking spaces No 2 and No 7 are indicated as “empty”. Further, “charge remaining time” indicating the current remaining charge time of each vehicle 2 may be included in the charge information. For example, when the parking space is not available, the remaining charge time may be used to indicate the current remaining charge time of each vehicle 2 to the waiting driver. In addition, it is conceivable to record “0 minutes” in the “remaining charge time” of a vacant parking space.

  Next, the processing unit 6 generates charging facility information, which will be described later, for guiding the vehicle 2 that has entered the parking space detected using the charging information to the parking space, and transmits the information to the vehicle 2 that has entered. . The charging facility information includes “map information”, “parking position”, “coordinates”, “type”, and “usage status”, and “map information” is information related to the charging station map recorded in the recording unit 7. is there.

In this example, “1” is recorded as an example of the parking space No1 shown in FIG. In the case of parking spaces No2 to No9, "2", "3", "9", etc. are recorded. In “coordinates”, the position coordinates of each parking space are recorded. For example, latitude and longitude may be used as the position coordinates. In this example, “X1, Y1”, “X2, Y2”, “X3, Y3”... “X9, Y9” are recorded. “Type” is an identifier for identifying whether the vehicle charging device 3 provided in each parking space is for quick charging or normal charging. For example, it is possible to indicate “rapid” when it is for quick charging, and “normal” when it is for normal charging. Further, when there is a parking space that does not include the vehicle charging device 3, for example, in the case of a parking space No. 4 as shown in FIG. 1, it is conceivable that “rapid” and “normal” are not indicated. “Usage status” indicates the current usage status of the vehicle charging device 3 and is an identifier indicating whether or not charging is in progress. “Usage status” is an aggregation of “usage status” of charging information acquired from each vehicle 2. For example, “use” is displayed when the vehicle is being charged or not charged, and “empty” is displayed when the vehicle 2 is not in the parking space. In the example of FIG. 1, parking spaces No 2 and No 7 are indicated as “use”, and parking spaces other than parking spaces No 2 and No 7 are indicated as “empty”.

  Further, “charge remaining time” indicating the current remaining charge time of each vehicle 2 may be included in the charge information. The “remaining charge time” is an aggregation of the “remaining charge time” of the charge information acquired from each vehicle 2. For example, when the parking space is not vacant, the remaining charge time may be used to indicate the current remaining charge time of each vehicle 2 to the waiting driver. In addition, it is conceivable to record “0 minutes” in the “remaining charge time” of a vacant parking space. The processing unit 6 may be a central processing unit (CPU) or a programmable device (such as a field programmable gate array (FPGA) or a programmable logic device (PLD)).

  The recording unit 7 records programs and data executed by the processing unit 6. The recording unit 7 may be, for example, a memory such as a read only memory (ROM) or a random access memory (RAM), a hard disk, or the like. The recording unit 7 may record data such as parameter values and variable values, or may be used as a work area at the time of execution.

  The communication unit 8 communicates with each of the entering vehicle 2 and the vehicle charging device 3. The communication unit 8 transmits a signal requesting charging information to the vehicle charging device 3 and receives a transmission signal including charging information transmitted from the vehicle charging device 3. In addition, the communication unit 8 transmits charging facility information used for presenting the driver to the input / output unit 18 of the vehicle 2 to the vehicle 2. As the communication method, for example, wireless communication, infrared communication, and the like can be considered.

The charging parking lot includes one or more vehicle charging devices 3.
In the example of FIG. 1, the vehicle charging device 3 is a vehicle charging device for normal charging, and the vehicle charging device 3 b is a vehicle charging device for quick charging. The vehicle charging device 3 in FIG. 2 includes a communication unit 9, a control unit 10, a recording unit 11, an input / output unit 12, and a charging unit 13, which will be described later.

The vehicle charging device 3 may be integrated with the vehicle detection device 4 or an input / output terminal for acquiring information from the vehicle detection device 4 in the vehicle charging device 3 so that the vehicle detection device 4 can be retrofitted. A power supply terminal may be provided.

When the communication unit 9 receives the charging request information from the parking guidance device 1, the communication unit 9 transmits the charging information to the parking guidance device 1. As the communication method, for example, wireless communication, infrared communication, or the like can be considered.
The control unit 10 performs control for supplying power to the vehicle 2. The control unit 10 of each vehicle charging device 3 receives the charging request information and acquires charging information from the recording unit 11 of each vehicle charging device 3. Next, the control unit 10 transmits the charging information to the parking guidance device 1 in the order determined in advance from the communication unit 9 of the vehicle charging device 3. For example, the time for transmitting the charging information after receiving the charging request information is set in advance in each vehicle charging device 3, the time is measured by a timer or the like, and the charging information is displayed when the set time is reached. It is possible to send. The control unit 10 may use a central processing unit (CPU) or a programmable device (such as a field programmable gate array (FPGA) or a programmable logic device (PLD)).

The recording unit 11 may record data such as parameter values and variable values, and can also be used as a work area.

  The input / output unit 12 may be a keyboard, a switch, or the like as an input unit. When a display is provided as the output unit, a touch panel provided on the display is considered as the input unit. Moreover, a display, a speaker, etc. can be considered as an output part.

  The charging unit 13 converts the power supplied from the primary power source through the power line into a voltage that can be supplied to the vehicle 2, and then supplies the vehicle with power. The charging unit 13 is, for example, a charging device for quick charging or a charging device for normal charging. In the case of the vehicle charging device 3b for quick charging, a quick charging cable and a plug are provided. In the case of the vehicle charging device 3a for normal charging, a normal charging cable and a plug are provided. The vehicle charging device 3 only needs to have one of the functions for quick charging and normal charging.

The vehicle 2 will be described.
The vehicle 2 in FIG. 1 includes a communication unit 15, a control unit 16, a recording unit 17, and an input / output unit 18, which will be described later. The communication unit 15 of the vehicle 2 receives a transmission signal including charging facility information transmitted from the parking guidance device 1. As the communication method, for example, wireless communication, infrared communication, and the like can be considered.

  The control unit 16 controls each unit of the vehicle 2 and generates image and audio data (output data) for efficiently guiding the vehicle 2 to be presented to the driver to an appropriate parking position using the charging facility information. That is, the control unit 16 detects a chargeable parking space with reference to the charging usage status included in each charging information, and selects the detected parking space with a preset priority. And the output data displayed on the input-output part showing the selected parking space on the map of a charging place is produced | generated using the parking position and map information corresponding to the selected parking space. Next, the control unit 16 outputs to the input / output unit 18 image and audio data that is efficiently guided to the parking position. The control unit 16 may use a central processing unit (CPU) or a programmable device (such as a field programmable gate array (FPGA) or a programmable logic device (PLD)). Note that the control unit 16 may generate the image or sound data to be output by the vehicle charging device 3 and output the image or sound data directly to the input / output unit 18 without newly generating image or sound data to be output.

  In addition, the process which produces | generates the output data which the control part 16 performs may be performed by the process part 6 of the parking guidance apparatus 1. FIG. In this case, the generated output data is transmitted from the parking guidance device 1 to the vehicle 2, and image and audio data that efficiently guides the parking position using the transmitted output data is output to the input / output unit 18.

  The recording unit 17 records programs, tables, data, and the like. The recording unit 17 is a memory such as a read only memory (ROM) or a random access memory (RAM). The recording unit 17 may record data such as parameter values and variable values, and can also be used as a work area.

  The input / output unit 18 outputs image or audio data that efficiently guides the vehicle 2 generated by the control unit 16 to an appropriate parking position. As the input unit, a keyboard, a switch, or the like can be considered. When a display is provided as the output unit, a touch panel provided on the display is considered as the input unit. Moreover, a display, a speaker, etc. can be considered as an output part. Note that the functions of the control unit 16 and the recording unit 17 may be realized using hardware of the car navigation system.

Operation | movement of the process part 6 of the parking guidance apparatus 1 is demonstrated.
FIG. 4 is a diagram illustrating an example of the operation of the processing unit 6. In step S1, the processing unit 6 acquires vehicle information indicating whether or not the vehicle 2 has entered the charging station from the vehicle detection device 4. In step S2, the processing unit 6 determines whether there is a vehicle 2 that has entered the charging station using the vehicle information. When it is entering, the process proceeds to step S3 (Yes), and when it is not entering, the process proceeds to step S1 (No).

In step S <b> 3, the processing unit 6 transmits charging request information to the vehicle charging device 3. When the vehicle charging device 3 receives the charging request information, the vehicle charging device 3 transmits the charging information to the processing unit 6.
In step S4, the processing unit 6 receives the charging information, and in step S5, the processing unit 6 collects the charging information. Thereafter, in step S6, the processing unit 6 transmits the charging facility information to the vehicle.

The operations of the parking guide device 1, the vehicle 2, and the vehicle charging device 3 will be described.
FIG. 5 is a diagram illustrating an example of operations of the parking guide device 1, the vehicle 2, and the vehicle charging device 3. In step S1, the parking guide device 1 acquires vehicle information indicating whether or not the vehicle 2 has entered the charging station from the vehicle detection device 4. In step S2, the parking guidance device 1 determines whether there is a vehicle 2 that has entered the charging station using vehicle information. In step S <b> 3, the parking guidance device 1 transmits charging request information to the vehicle charging device 3 when the vehicle 2 is entering. In this example, only one vehicle charging device 3 is shown for simplicity of explanation, but actually, charging request information is transmitted to a plurality of vehicle charging devices 3 simultaneously or sequentially.

  In step T1, each vehicle charging device 3 receives charging request information. In step T2, when each vehicle charging device 3 receives the charging request information, the charging information is acquired from the recording unit 11 of each vehicle charging device 3. In step T3, each vehicle charging device 3 transmits charging information of each vehicle charging device 3 to the parking guidance device 1 in a predetermined order.

  In step S4, the parking guidance device 1 receives charging information from each of the vehicle charging devices 3, and in step S5, the parking guidance device 1 collects the charging information. For example, charging facility information 32 as shown in FIG. 3 is generated. Thereafter, in step S6, the processing unit 6 transmits the charging facility information to the vehicle.

  In step r1, the vehicle 2 receives the charging facility information, and in step r2, the image or audio data (output data) for efficiently guiding the vehicle 2 to be presented to the driver to the driver using the charging facility information is output. Generate.

The data generation process will be described. FIG. 6 is a diagram illustrating an example of the operation of the control unit of the vehicle. In step S <b> 61, the control unit 16 receives charging facility information from the communication unit 15.
In step S62, the control unit 16 searches for charging facility information, and in step S63, a parking position is extracted. For example, “usage status” is searched in order from the top of the acquired charging facility information 32 to detect an empty “parking position”. In this example, “empty” parking spaces No1, No3, No6, No8, and No9 are detected. Next, the types of the vehicle charging devices 3a and 3b corresponding to the parking space detected by the control unit 16 are extracted. However, when only the parking space is presented to the driver, the types of the vehicle charging devices 3a and 3b may not be extracted.

  In step S64, the control unit 16 generates output data. For example, the control unit 16 selects a small parking space from the identifiers recorded in the “parking position”, and records the selected parking space and the parking space recorded in the map information in the recording unit 17 in association with each other. . Further, the vehicle charging devices 3a and 3b extracted in the parking space are associated and recorded in the recording unit 17. By using the data recorded in the recording unit 17 by the generation process, image or audio data that efficiently guides the entering vehicle 2 to the parking space that is an appropriate parking position is generated. That is, image data in which the selected parking space is displayed on the parking lot map is generated. Further, voice data for guiding to the selected parking space is acquired from the recording unit 17 and data for performing voice guidance is generated.

  In step r <b> 3, the control unit 16 outputs to the input / output unit 18 image and audio data that is efficiently guided to the parking position. For example, it is conceivable to display as indicated by a dotted line 71 in FIG. FIG. 7 is a diagram illustrating an example of an image displayed for efficiently guiding the vehicle to the parking position. However, the display of the parking position is not limited to the display as indicated by the dotted line 71 in FIG. 7, and may be any display as long as the driver can guide the vehicle to the parking position. Further, the parking space and the vehicle charging device 3 may be guided by voice without displaying the types of the parking space and the vehicle charging device 3. For example, it is conceivable to provide voice guidance such as “Please move to the vehicle charging device for normal charging in the parking space No. 1”.

  In step r2, a parking space having a small “parking position” is selected, but instead of selecting a parking space having a small “parking position”, the type of the parking space close to the entrance and the vehicle charging device 3 is input / output unit. 18 may be output. The selection of the parking space close to the entrance can be considered by arranging the “parking positions” of the charging facility information 32 in the order closest to the entrance. For example, it can be considered that the parking spaces are No. 5, No. 6, No. 1,. And the control part 16 may detect the parking space near an entrance by searching in order from the top of charging equipment information as demonstrated in the said production | generation process.

Further, when there are two types of the vehicle charging device 3, the parking space for quick charging and the parking space for normal charging may be displayed in order from the smallest “parking position” or from the closest to the entrance.
If all the vehicle charging devices 3 are of the same type, only the parking space may be displayed or voiced.

  In the above steps r2 and r3, the parking spaces are selected in ascending order of the “parking position” or in the order of closest to the entrance. When there are many, it is not necessary to guide. In the case of a wide parking station, the vehicle may be guided after it is almost full. For example, detection may be performed with reference to the identifier of “usage status”, and the vehicle may be guided when a predetermined number of vehicles are parked.

  Furthermore, when the vehicle 2 receives the charging facility information via the communication unit 15, the vehicle 2 may determine an optimal parking method using the normal inlet of the host vehicle and the inlet position information indicating the position of the rapid inlet. The optimal parking method is, for example, parking with the front or rear part of the vehicle 2 in front, or when the vehicle charging device 3b for normal charging or the vehicle charging device 3a for quick charging is viewed from the driver's seat of the vehicle 2. Information indicating whether to park on the right side or on the left side.

Next, a recommended parking method for the vehicle 2 in the parking lot is created using the map information of the parking station where the vehicle charging device 3 is installed and the above-described optimal parking method.
The creation of the recommended parking method means that, for example, when the parking lot has a structure in which the front part or the rear part of the vehicle 2 is parked on the outer periphery of the parking lot, the front part of the vehicle 2 is put in and parked first. Or it is to create information that can display on the map whether the vehicle 2 is parked first.

  If the recommended parking method is obtained, the recommended parking method is output to the input / output unit 18. For example, as shown in FIG. 7, the vehicle charging device 3b for normal charging or the vehicle charging device 3a for quick charging is displayed on the map, and the vehicle 2 suitable for charging the corresponding vehicle 2 at these charging stations. The parking position and the front-rear direction of the vehicle 2 may be displayed on a map. By viewing the above information displayed on the input / output unit 18, the driver is suitable for charging when charging using the vehicle charging device 3b for normal charging or the vehicle charging device 3a for quick charging. It is possible to know the parking position and the front-rear direction of the vehicle.
