  By the way, in the electric vehicle telephone control system disclosed in Patent Document 1 and the vehicle remote control system disclosed in Patent Document 2, it is important to grasp the state of the vehicle to be controlled. For this reason, in the above conventional system, the user confirms information displayed on the mobile phone or the mobile terminal by providing various types of vehicle data representing the state of the vehicle to the mobile phone or mobile terminal owned by the user. In addition, the state of the vehicle is grasped.

  However, for a user who confirms information displayed using a mobile phone or a mobile terminal, the origin of the vehicle data is not clearly identified (distinguishable). For example, as described above, the mobile phone or the mobile terminal The vehicle data provided to the vehicle is vehicle data output directly from the vehicle, ie, real-time raw data, or vehicle data output indirectly from the center that is stored as backup data in an updatable manner, ie, past data It becomes extremely difficult to recognize what is. As a result, it becomes difficult for the user to determine the reliability that changes depending on the newness of the information displayed based on the provided vehicle data, and the vehicle state may not be properly grasped.

  The present invention has been made to address the above-described problems, and one of its purposes is a vehicle display device that can easily grasp the origin of vehicle data related to the vehicle information displayed on the information terminal owned by the present invention. Is to provide.

  In order to achieve the above object, a vehicle information display device according to the present invention displays various vehicle information relating to a vehicle using an information terminal owned by a user independently of the vehicle. The vehicle information display device according to the present invention is characterized in that the information terminal displays vehicle information in the first display mode or the second display mode according to the origin (origin) of various vehicle data representing the state of the vehicle. It is to be displayed.

  That is, the first display mode is a display mode when the information terminal displays vehicle information based on various vehicle data representing the state of the vehicle acquired directly from the vehicle. Further, unlike the first display mode, the second display mode is a display mode when displaying vehicle information based on the various vehicle data obtained indirectly from the outside of the vehicle. Here, the display mode includes setting a display color and a background color when displaying vehicle information, and interlocking various functions of the information terminal when displaying vehicle information. The first display mode and the second display mode can be identified (differentiated) by changing the setting and the function to be linked.

  In this case, more specifically, if the information terminal is configured to be able to directly acquire the various types of vehicle data by performing short-range communication with short-range communication means mounted on the vehicle, the short-range When the vehicle is in a state where short-distance communication is possible with the communication unit, the vehicle information based on the various vehicle data directly acquired from the vehicle is displayed by the first display mode, and the short-distance communication unit The vehicle information based on the various vehicle data obtained indirectly from the outside of the vehicle can be displayed by the second display mode when the vehicle is not in a state in which short-range communication is possible.

  In these cases, the various vehicle data indirectly acquired by the information terminal is provided outside the vehicle, for example, and is stored so that the various vehicle data from the vehicle can be updated as backup data. In this case, the information terminal indirectly communicates the various vehicle data stored as backup data in the center by communicating with communication means provided in the center. Can be obtained. Here, in this case, for example, the information terminal receives the various vehicle data acquired when the short-range communication with the short-range communication means mounted on the vehicle is possible. Can be output to the center by communicating with the communication means.

  And in these cases, if the vehicle is configured to be able to travel using the power of a battery that can be charged from outside the vehicle, the information terminal may acquire the direct or indirect, for example, Based on data representing the state of charge of the battery included in various vehicle data, the vehicle information including at least the amount of charge of the battery, the necessity of charging of the battery, and the travelable distance using the power of the battery. The display can be performed in the first display mode or the second display mode.

  According to these, when the vehicle and the information terminal are capable of short-range communication, for example, the information terminal acquires various types of vehicle data (data indicating the state of charge of the battery) directly from the vehicle, and The vehicle information can be displayed by one display mode. That is, the vehicle information displayed by the first display mode is new vehicle information based on new vehicle data acquired directly (in real time) from the vehicle. On the other hand, when the short distance communication between the vehicle and the information terminal is impossible, the information terminal displays various vehicle data (battery of the battery) stored as backup data outside the vehicle (specifically, a center provided outside). Data representing the state of charge) can be acquired, and the vehicle information can be displayed in the second display mode. That is, the vehicle information displayed by the second display mode is old vehicle information based on past old vehicle data acquired indirectly via the outside (center) of the vehicle.

  Thereby, the user recognizes (distinguishes) whether the vehicle information displayed on the information terminal is in the first display mode or the second display mode, so that the origin (origin of the vehicle data) ), It is possible to easily determine whether the vehicle information is new vehicle information based on real-time vehicle data (raw data) or old vehicle information based on vehicle data backed up in the past. Therefore, the user can accurately determine the reliability of the vehicle information displayed (presented) by the information terminal, and can appropriately respond according to the determined reliability. For example, in a situation where vehicle information including a battery charge amount, whether or not a battery needs to be charged, and a travelable distance using battery power is presented, the user can display the vehicle information in the first display mode. It can be determined that the vehicle information is highly reliable and the battery can be charged, or if it is displayed by the second display mode, it can be determined that the vehicle information is inferior in reliability and can be handled as reference information. .

It is the schematic of the information display system of the vehicle provided with the vehicle information display apparatus which concerns on embodiment of this invention. It is a flowchart for the vehicle information display program executed by the main control unit of the portable information terminal of FIG. It is the schematic for demonstrating the 1st display mode which displays the vehicle information (charging information) based on the vehicle data (SOC data) which the portable information terminal of FIG. 1 acquired directly from the vehicle.

  The CAN communication line 120 is connected to a short-range communication control device 130 as a short-range communication means for realizing short-range communication with the portable information terminal 300. In this embodiment, Bluetooth (registered trademark) is adopted as a communication method of the short-range communication control device 130 as will be described later. However, as another communication method, for example, Wi-Fi ( It goes without saying that other short-distance communication methods such as registered trademark) and wired communication using a cradle can be adopted. In the present embodiment, the information transfer ECU 110a and the short-range communication control device 130 are implemented separately, but the information transfer ECU 110a and the short-range communication control device 130 can be configured integrally. Needless to say.

  The vehicle information center 200 acquires various types of vehicle data from the vehicle 100 via the portable information terminal 300 and provides various types of vehicle data stored as backup data to the user of the vehicle 100 via the portable information terminal 300 It is. The vehicle information center 200 is provided with a server 210 whose main component is a microcomputer. The server 210 is connected to the external communication network 400 to control communication, a vehicle data server 212 that manages vehicle data as backup data, a user information server 213 that manages vehicle user information, A vehicle data storage unit 214 that stores a database of vehicle data and a user information storage unit 215 that stores a database of user information are provided. The server 210 associates an ID for identifying the vehicle 100 (information corresponding to a registration number or a chassis number) and an ID for identifying the user (user name, mobile phone number of the mobile information terminal 300, mail address, etc.) with each other. Is stored, and by specifying one of the IDs, the information specified by the other ID can be extracted.

  A portable information terminal 300 as a vehicle information display device owned by a user includes an external communication control unit 301 that is a communication interface for connecting to an external communication network 400, and short-range communication (more from Bluetooth®). Specifically, a short-range communication control unit 302 that is a communication interface for realizing short-range wireless communication), a GPS unit 303 that detects the current position coordinates of the portable information terminal 300 based on radio waves from GPS satellites, and a display Touch panel type liquid crystal display 304 that also serves as a controller and an operating device, main controller 305 that executes communication control, display control, and various applications using a microcomputer as a main component, and stores various data such as application programs And a non-volatile memory 306. Here, specifically, a mobile phone such as a smartphone, a tablet-type information terminal, or the like can be employed as the mobile information terminal 300.

  Next, a vehicle information display device applied to the vehicle information display system configured as described above will be described. In the vehicle information display device according to the present embodiment, the vehicle 100 and the portable information terminal 300 perform short-distance wireless communication, and the portable information terminal 300 and the vehicle information center 200 perform long-distance communication via the external communication line network 400. It is realized. Specifically, the information transfer ECU 100a on the vehicle 100 side acquires various types of vehicle data (for example, SOC data representing the SOC of the battery) output from the plurality of vehicle ECUs 110 provided in the vehicle 100. The acquired various vehicle data are stored in a predetermined storage position of the nonvolatile memory so as to be sequentially searchable. And information transfer ECU110a transfers the various vehicle data memorize | stored with respect to the portable information terminal 300 registered previously using the near field communication control apparatus 130. FIG.

  Here, registration of the portable information terminal 300 in the present embodiment will be described. In the present embodiment, as described above, the short-range communication control device 130 provided in the vehicle 100 and the portable information terminal 300 are connected so as to be capable of short-range wireless communication using Bluetooth (registered trademark). Thus, when communicating using Bluetooth (registered trademark), by performing pairing processing between the short-range communication control device 130 and the portable information terminal 300, the short-range communication control device 130 can The portable information terminal 300 can be registered as a connection partner. Note that the pairing process itself for communication using Bluetooth (registered trademark) is not directly related to the present invention, and will be briefly described below.

  When using Bluetooth (registered trademark), a pairing process for specifying (registering) a connection partner is required. For example, when the short-range communication control device 130 and the portable information terminal 300 are paired according to a general procedure, in other words, the portable information terminal 300 is registered as a connection destination of the short-range communication control device 130. Assuming the case, when the user (driver) of the vehicle 100 performs a predetermined registration request operation, the information transfer ECU 110a controls the short-range communication so that it can be searched from the portable information terminal 300 present in the surroundings. The device 130 is set in a searchable state. On the other hand, after the predetermined registration request operation, the user of the vehicle 100 puts the short-range communication control unit 302 in the search state so that the portable information terminal 300 searches for the short-range communication control device 130 via the main control unit 305. Set. By doing in this way, the portable information terminal 300 searches for nearby short-range communication devices including the short-range communication control device 130 and displays a list of search results on the touch panel display 304. A unique device address is assigned to each near field communication device, and the device address of the searched device or an arbitrarily determined device name is displayed in the search result list.

  Next, when the user selects a desired connection partner, that is, the short-range communication control device 130 from the list of search results, a link key is generated between the portable information terminal 300 and the short-range communication control device 130. The pairing process is completed by storing the link key and the device address of the other party (specifically, the vehicle 100 and the portable information terminal 300). On the other hand, depending on the specifications of the short-range communication device, it may be necessary to input a passkey (PIN code) when selected by the user, and the link key is generated by inputting the correct passkey.

  As described above, the Bluetooth (registered trademark) communication is used by sharing the device address and the link key between the vehicle 100 (more specifically, the short-range communication control device 130) and the portable information terminal 300. When the pairing process is completed, the user (driver) gets on the vehicle 100 with the portable information terminal 300, or is positioned near the periphery of the vehicle 100 and an ignition switch (not shown) is omitted. Operation automatically establishes a connection. Alternatively, when the user (driver) gets on the vehicle 100 with the portable information terminal 300 and performs a predetermined connection operation, the connection is established. When connection (pairing) is established between the short-range communication control device 130 and the portable information terminal 300 in this way, for example, an indicator provided in a meter cluster (not shown) is lit, and the user ( The driver can be informed that the connection has been established.

  As long as it is registered as a connection destination in the short-range communication control device 130 on the vehicle 100 side as described above, in the portable information terminal 300, the main control unit 305 is transferred from the information transfer ECU 110a on the vehicle 100 side. Vehicle data (eg, SOC data) is acquired and temporarily stored in the nonvolatile memory 306. The main control unit 305 uses the short-range communication control unit 302 to store various vehicle data temporarily stored when the short-range communication control device 130 on the vehicle 100 side has been established. The vehicle information based on the vehicle is displayed on the touch panel display 304 in a display mode to be described later and presented to the user (driver). On the other hand, the main control unit 305 stores various vehicle data (for example, SOC data) temporarily stored in the nonvolatile memory 306 via the external communication control unit 301 and the external communication line network 400. 200. The vehicle information center 200 stores backup data when the portable information terminal 300 has not established near field communication control with the near field communication control device 130 on the vehicle 100 side using the near field communication control unit 302. The various types of vehicle data (for example, SOC data) are transmitted to the portable information terminal 300 via the communication control unit 211 and the external communication line network 400.

  In order to realize such a vehicle information display device, the main control unit 305 of the portable information terminal 300 owned by the user (driver) of the vehicle 100 repeatedly executes the vehicle information display program shown in FIG. Hereinafter, this vehicle information display program will be described in detail.

  The main control unit 305 (more specifically, the CPU) starts execution of the vehicle information display program shown in FIG. 2 in step S10, and proceeds to step S11. In step S <b> 11, the main control unit 305 determines whether or not near field communication control device 130 on the vehicle 100 side is currently established with near field communication using the near field communication control unit 302. More specifically, the main control unit 305 is a user (driver) riding on the vehicle 100 or located around the vehicle 100, and the short-range communication control unit 302 is located near the vehicle 100. When various vehicle data (for example, SOC data, etc.) can be acquired directly from the information transfer ECU 110a through the connection established with the distance communication control device 130, the determination is “Yes” and the process proceeds to step S12. On the other hand, the user (driver) is away from the vehicle 100, and the short-range communication control unit 302 cannot directly establish a connection with the short-range communication device 130 on the vehicle 100 side, and directly from the information transfer ECU 110a. When various vehicle data (for example, SOC data, etc.) cannot be acquired, it is determined as “No” and the process proceeds to step S13.

  In step S <b> 12, the main control unit 305 uses the short-range communication unit 302 to store SOC data as various types of vehicle data directly acquired from the information transfer ECU 110 a of the vehicle 100 in a predetermined storage position of the nonvolatile memory 306. To remember. Subsequently, the main control unit 305, based on the acquired SOC data, the charge amount of the battery mounted on the vehicle 100 as vehicle information, the necessity of charging according to the charge amount, the travelable distance using the battery power, and the like Is calculated. Then, the main control unit 305 obtains the vehicle information to be displayed directly (in other words, in real time) from the vehicle 100 when displaying the calculated charge amount, the necessity of charging, and the travelable distance on the touch panel display 304. It is displayed in the first display mode that allows the user (driver) to easily grasp that the data is based on the SOC data.

  Specifically, in the first display mode, for example, as shown in FIG. 3, the vehicle data update information indicates that the displayed vehicle information (charge information) is updated based on the current SOC data. Can be specified by In this case, the vehicle data update information is based on the SOC data directly acquired from the vehicle 100 by short-range wireless communication, in other words, a display color set in advance to indicate the first display mode. Can be shown.

  Further, as shown in FIG. 3, in the first display mode, the background color on the touch panel display 304 is changed to a preset background color, or is shown to the user (driver). The display color of the information figure (the amount of charge shown by the schematic battery diagram in FIG. 3) is changed to a preset display color, or the vehicle information is necessary for charging and can be driven The display color such as distance can be changed to a preset color.

  That is, in these cases, the amount of charge, the necessity of charging, and the travelable distance displayed as vehicle information on the Dutch panel display 304 are based on SOC data directly acquired from the vehicle 100 by short-range wireless communication. The display color is changed to a preset display color corresponding to the first display mode indicating that the image is displayed.

  In addition, when displaying vehicle information (charging information) in the first display mode, the flashing pattern and flashing color of various lights provided on the portable information terminal 300 are changed to, for example, fast flashing. Can do. That is, the amount of charge, the necessity of charging, and the travelable distance displayed as vehicle information on the Dutch panel display 304 include various blinking lights and blinking colors and blinking colors that are preset in correspondence with the first display mode. , Displayed in the state changed to the blinking cycle.

  Furthermore, when displaying vehicle information (charging information) in the first display mode, the vibration period, rhythm, and strength of vibration (vibration) of the portable information terminal 300 are changed to, for example, a fast period, rhythm, and strong vibration. Can show. Or when displaying vehicle information (charge information) by the 1st display mode, the state which changed the sound emitted from personal digital assistant 300 into the preset sound can be shown. That is, the charge amount, the necessity of charging, and the travelable distance displayed as vehicle information on the Dutch panel display 304 are in a state in which the sound emitted is changed to a sound set in advance corresponding to the first display mode. Is displayed.

  Then, when the main control unit 305 displays vehicle information (charging information) on the touch panel display 304 in the first display mode and presents it to the user (driver), the main control unit 305 proceeds to step S14 and executes the vehicle information display program. Exit once. Then, the main control unit 305 starts executing the program again in step S10 after a predetermined short time has elapsed.

  In step S13, the main control unit 305 cannot acquire various vehicle data from the information transfer ECU 110a of the vehicle 100 by short-range wireless communication, and therefore uses the external communication control unit 301 and the external communication line network 400. Then, the SOC data represented by the backup data stored and managed by the vehicle data server 212 in the vehicle data storage unit 214 is acquired from the vehicle information center 200, and the acquired SOC data is stored in the nonvolatile memory 306. Store in memory location. Subsequently, based on the acquired SOC data, the main control unit 305 charges the battery mounted on the vehicle 100 at the time of being stored (registered) in the vehicle information center 200 as backup data, and charging according to the charged amount. The necessity distance and the travelable distance using the power of the battery are calculated. Then, the main control unit 305 displays back-up SOC data (in other words, indirectly obtained from the vehicle information management center 200 when displaying the calculated charge amount, the necessity of charging, and the travelable distance on the touch panel display 304. The second display mode allows the user (driver) to easily grasp that the data is based on past SOC data.

  Specifically, for example, as shown in FIG. 4, it can be clearly indicated by the vehicle data update information that the displayed vehicle information is updated based on the SOC data at the time of backup. In this case, the vehicle data update information is based on the SOC data obtained indirectly from the vehicle information center 200 by long-distance communication, in other words, a display set in advance to indicate the second display mode. Can be indicated by color. Further, as shown in FIG. 4, regarding the display color and background color according to the second display mode of the charge amount, the necessity of charging, and the travelable distance displayed as vehicle information on the Dutch panel display 304, the vehicle information center 200 In order to indicate that it is based on SOC data acquired indirectly by long-distance communication, the color is changed to a preset color so as to be different from the first display mode.

  In addition, regarding the blinking pattern, the blinking color, and the blinking cycle of various lights when the charge amount, the necessity of charging, and the travelable distance are displayed as vehicle information on the Dutch panel display 304 in the second display mode, Different from the display mode, it is changed to a preset blinking pattern, blinking color, or blinking cycle. Further, regarding the vibration and sound when displaying the charge amount, the necessity of charging and the travelable distance as vehicle information on the Dutch panel type display 304 in the second display mode, they are preset so as to be different from the first display mode. It can be changed and displayed on the screen.

  Then, when the main control unit 305 displays vehicle information (charging information) on the touch panel display 304 in the second display mode and presents it to the user (driver), the main control unit 305 proceeds to step S14 and executes the vehicle information display program. Exit once. Then, the main control unit 305 starts executing the program again in step S10 after a predetermined short time has elapsed.

  As can be understood from the above description, according to the above embodiment, the vehicle 100 (more specifically, the near field communication control device 130) and the portable information terminal 300 (more specifically, the near field communication control unit 302) are provided. When the near field communication is possible, the main control unit 305 acquires vehicle data (SOC data) directly from the information transfer ECU 110a on the vehicle 100 side, and displays the vehicle information (charging information) in the first display mode. can do. That is, the vehicle information (charging information) displayed in the first display mode is new vehicle information based on new vehicle data (SOC data) acquired directly (in real time). On the other hand, when the vehicle 100 (more specifically, the near field communication control device 130) and the portable information terminal 300 (more specifically, the near field communication control unit 302) are incapable of near field communication, the main control unit 305 Vehicle data (SOC data) stored as backup data in the information center 200 can be acquired, and vehicle information (charging information) can be displayed in the second display mode. That is, the vehicle information (charging information) displayed in the second display mode is old vehicle information based on past old vehicle data (SOC data) acquired indirectly via the vehicle information center 200.

  Thereby, the user (driver) recognizes (discriminates) whether the vehicle information (charge information) displayed on the touch panel display 304 is the first display mode or the second display mode. This makes it easy to determine whether the vehicle information is new vehicle information (charging information) based on real-time vehicle data (raw data) or old vehicle information (charging information) based on vehicle data (backup data) backed up in the past. Can be determined. Therefore, the user (driver) can accurately determine the reliability of the vehicle information displayed (presented) by the portable information terminal 300, and can appropriately respond according to the determined reliability. For example, a user (driver) charges a battery according to highly reliable vehicle information (charge information) displayed in the first display mode, or is inferior in reliability displayed in the second display mode. Information (charging information) can be treated as reference information.

  In the above embodiment, vehicle data (SOC data) at the present time or backed up time, in other words, vehicle data (SOC data) acquired directly from the vehicle 100 side or a vehicle acquired indirectly from the vehicle information center 200. The vehicle information (charging information) is displayed and presented to the user (driver) by the first display mode or the second display mode indicating that the data is updated based on the data (SOC data). Carried out. In this case, as shown in FIG. 5, for example, when the user (driver) performs a touch operation (tap operation) on the information display portion displayed on the touch panel display 304, specifically, the vehicle data update information portion. Information indicating the origin (origin) of the vehicle data, such as whether the vehicle data (SOC data) is obtained directly from the vehicle 100 side or indirectly from the vehicle information center 200 is displayed. It is also possible to implement.

  Thus, by displaying and presenting information representing the origin (origin) of the vehicle data, the user (driver) can easily improve the reliability of the vehicle information (charging information) displayed on the touch panel display 304. Judgment can be made. Therefore, also in this modified example, as in the above embodiment, the user (driver) can confirm the origin (origin) of various types of vehicle data when necessary and trust the displayed vehicle information. Therefore, it is preferable that the user (driver) does not need to always remember the display color changed according to the first display mode and the second display mode.

  In carrying out the present invention, the present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the object of the present invention.

  For example, in the embodiment and the modified example, the displayed vehicle information (charging information) is updated based on the vehicle data (SOC data) at the current time or the vehicle data (SOC data) at the time of backup. In order to make it clear, as shown in FIG. 3 to FIG. 5, the display color of the vehicle data update information by characters is changed. In this case, in order to make the visibility by the user (driver) more favorable, for example, a pattern (figure) representing the vehicle 100 or the vehicle information center 200 is displayed instead of or in addition to the vehicle data update information. It is also possible to do. Even in this case, the same effects as those of the above embodiment and the modification can be obtained.

  In the embodiment and the modification described above, the main control unit 305 of the portable information terminal 300 performs the near field communication control device 130 on the vehicle 100 side and the proximity on the portable information terminal 300 side in step S11 in the vehicle information display program. It was implemented so as to determine whether or not near field communication was established with the distance communication control unit 302. In this case, for example, the main control unit 305 determines the distance between the vehicle 100 and the portable information terminal 300 based on the current position of the terminal 300 and the current position of the vehicle 100 detected by the GPS unit 303 of the portable information terminal 300. It is also possible to carry out so as to determine whether or not the calculated distance is a short-distance communication distance. In this case, the main control unit 305 displays vehicle information (charging information) in the first display mode in step S12 if the calculated distance is a short-distance communication distance, and the calculated distance is a short distance. If the communication is impossible, vehicle information (charging information) can be displayed in the second display mode in step S13. Therefore, also in this case, the same effects as those of the above-described embodiment and modification can be obtained.

  In this case, the main control unit 305 of the portable information terminal 300 establishes near field communication between the near field communication control device 130 on the vehicle 100 side and the near field communication control unit 302 on the portable information terminal 300 side. Instead of determining whether or not it is possible, calculating the distance between the vehicle 100 and the portable information terminal 300, and determining whether or not the calculated distance is a short-distance communicable distance. Thus, for example, the information transfer ECU 110a on the vehicle 100 side can execute the determination process, or the server 210 of the vehicle information center 200 can execute the determination process. Even in this case, the same effects as those of the embodiment and the modification can be obtained.

  Furthermore, in the said embodiment and modification, it implemented so that the vehicle information center 200 provided outside the vehicle memorize | stores vehicle data as backup data. In this case, for example, the portable information terminal 300 stores vehicle data as backup data in the nonvolatile memory 306, and stores the vehicle data in the nonvolatile memory 306 when short-range communication with the vehicle 100 is impossible. It is also possible to display and present vehicle information (charging information) in the second display mode based on vehicle data. Even in this case, the same effects as those of the embodiment and the modification can be expected. In this case, vehicle data acquired directly from the vehicle 100, backed up vehicle data acquired indirectly from the vehicle information center 200, and vehicle data stored as backup data in the nonvolatile memory 306 are distinguished from each other. You may do it.
