Description

  The present invention analyzes an in-vehicle information communication device that communicates in-vehicle information transmitted via a bus of an in-vehicle network to a computer wirelessly or by wire, and in-vehicle information acquired through the in-vehicle information communication device. The present invention relates to an in-vehicle information utilization network system that provides users with information.

  In automobiles, control is performed by a plurality of ECUs (Electric Control Units) for each system such as a powertrain system, a body control system, and a safety system. In each system, a LAN (Local Area Network) connects the ECUs in order to reduce the number of wires connecting the ECUs. Typical in-vehicle LANs include CAN (Control Area Network) and MOST (Media Oriented Systems Transport).

  In recent years, automobiles have been required to be equipped with an on-board diagnosis (OBD system) system. This system detects an abnormality in each part of the vehicle, turns on a warning lamp or the like when the abnormality occurs, and stores and holds the contents of the failure. In this system, each unit is monitored by a sensor, and a failure is determined by an ECU based on information from the sensor.

  On the other hand, a high-accuracy driving test sensor is attached to the car, and during the driving test, each sensor information from the driving test sensor and the sensor that is pre-installed in the car as a standard is transmitted via the CAN bus, It is stored in the storage device of the inspection instrument. Thereafter, the results of the running test are evaluated by analyzing each sensor information in the storage device.

  For this reason, various types of sensors are attached to automobiles that are rapidly becoming electrified, and a large amount of sensor information flows in the in-vehicle network. Expectations for IT services using such a vast amount of sensor information are expected. (For example, Patent Document 1 and Non-Patent Document 1).

  Various types of vehicle travel information are transmitted to a mobile phone via a wireless LAN, for example, from a dedicated module of the second generation on-board computer diagnostic device (OBDII), and the mobile phone's drive eco-support application, for example, Whether or not the vehicle is an eco-drive is diagnosed from information such as the vehicle speed (Non-Patent Document 1).

  In general, communication is roughly divided into wired communication and wireless communication. In wireless communication, since communication failure such as radio wave interference occurs, the system is designed on the assumption that communication is interrupted. Therefore, wired communication is adopted in the field where high reliability is required. In an in-vehicle network, a wired communication standard such as a CAN standard is often adopted, and reliability is ensured.

The in-vehicle information communication device 20 includes a communication unit 23 that includes a plurality of channels and performs near field communication as an output unit.

  The in-vehicle information communication device 20 includes a control unit 24. The control unit 24 adds date and time information to the in-vehicle information input from the first connection unit 21 and the second connection unit 22, and further in the order of input in a normal state. It distributes and distributes in order to each channel of the communication part 23, and outputs. The control unit 24 includes a storage element such as a ROM and a RAM in addition to the CPU.

  The in-vehicle information communication apparatus 20 includes a USB connection unit 25. The USB terminal 17 is connected to the USB connection unit 25, and control information and control programs in the storage element of the control unit 24 are rewritten from the computer 18 via the USB cable 17a. The information in the storage element in the control unit 24 can be taken out to the computer 18. In the in-vehicle information communication apparatus 20, the computer 18 is connected to the USB connection unit 25 as a device including a power supply unit and a USB terminal. The computer 18 as a device is connected to the USB connection unit 25 via the USB terminal 17, and power can be supplied to the control unit 24 via the USB terminal 17 from power supply means (not shown) in the computer 18.

  The control unit 24 monitors whether the in-vehicle network system 11 is connected to the first connection unit 21 and monitors whether the computer 18 is connected to the USB connection unit 23 via the USB cable 17a. And the control part 24 selects alternatively the electric power feeding from the battery in the vehicle-mounted network system 11, and the electric power feeding from the computer 18, for example. The in-vehicle information communication apparatus 20 includes a voltage control unit 26, and the voltage control unit 26 selects power supply from a battery or power supply from the computer 18 in the in-vehicle network system 11 under the control of the control unit 24, and converts the voltage. To supply power to the control unit 24.

  The in-vehicle information communication device 20 further includes a switch 27, and by manually turning on / off the switch 27, either the power supply from the in-vehicle network system 11 or the power supply from the computer 18 is operated. You can also select whether or not to operate. The selection control has priority over the control of the control unit 24. Thus, the energy stored in the battery in the in-vehicle network system 11 is prevented from being supplied to the control unit 24 unnecessarily.

  Here, the power supply from the battery in the in-vehicle network system 11 via the first connection unit 21 may be supplied to the inspection system 12 connected to the second connection unit 22 via the voltage control unit 26. That is, the in-vehicle information communication apparatus 20 not only transfers the in-vehicle information to the mobile computer 13, but also supplies power to the inspection system connected to the second connection unit 22, and in the example shown in FIG. It becomes. Further, what is connected to the second connection unit 22 may be not only the inspection system 12 but also various devices. In such a form, in-vehicle information may not be input to the control unit 24 via the second connection unit 22. In this case, the in-vehicle information is input from the in-vehicle network system 11 via the first connection unit 22. Date and time information is attached to the in-vehicle information.

  The mobile computer 13 corresponds to, for example, a portable information terminal, a notebook computer, a tablet, or the like. The mobile computer 13 includes an input unit (not shown) that receives input from the user and a display unit (not shown) that displays to the user. The mobile computer 13 includes a communication unit 13a that has a plurality of channels and performs short-range wireless communication, a control unit 13b that includes a CPU, and a storage unit 13c that includes various media such as a ROM and a RAM. The control unit 13b processes a data compression program stored in the storage unit 13c and a program for uploading to the network. Moreover, you may make it analyze the vehicle-mounted information transmitted from the vehicle-mounted information communication apparatus 20, for example, sensor information, by reading and executing the analysis processing program in the memory | storage part 13c. In the embodiment shown in FIG. 1, the computer that communicates with the in-vehicle information communication apparatus 20 is the mobile computer 13, but it may be a non-mobile computer.

  The mobile computer 13 includes a transmission / reception unit 13 d and can upload and download various information to the server device 14 via the router 16. The mobile computer 13 may be, for example, a smartphone. In this case, uploading various information such as in-vehicle information to the server device 14 via various networks (not shown) may provide services from the server device 14. You can also receive.

  The server device 14 includes a transmission / reception unit 14a, a control unit 14b, a database 14c, and a transmission / reception unit 14d. The transmission / reception unit 14a receives information uploaded from the mobile computer 13 via the router 16, and outputs the uploaded information to the control unit 14b. The control unit 14b stores the uploaded information in the database 14c. The database 14c is, for example, a SQL (Structured Query Language) database. When the application stored in the client terminal 15 is executed and a search request for the database 14c is made to the control unit 14b via the transmission / reception unit 14d, the control unit 14b receives the request and updates the database 14c. The search is performed, and the search result is returned to the client terminal via the transmission / reception unit 14d. Here, the client terminal 15 corresponds to a portable information terminal, various computers used for vehicle development and vehicle inspection, and the like. The transmission / reception units 14a and 14d of the server device 14 may be shared. The server device 14 is a so-called cloud computer and is connected to the outside via various communication networks.

  In the first embodiment of the present invention, vehicle information including sensor information, for example, CAN information, is sequentially input from the first connection unit 21 and the second connection unit 22 by the control unit 24 in the vehicle-mounted information communication device 20. At the time of input, information related to the input date and time (hereinafter simply referred to as “date and time information”) is attached to each vehicle information. The date and time information is obtained by adding the input date information and the input time information. Instead of attaching date / time information to the in-vehicle information, the control unit 24 may add only the time information to the in-vehicle information. The sensor information includes an ID that is an identifier for identifying which sensor information and sensor data. In addition to sensor information, there are operation information of devices such as switches, headlights, turn signals, etc. in automobiles, for example, vehicle speed / engine speed, air conditioner operation commands, time information from GPS, areas where automobiles exist Time difference information according to the time zone of the vehicle, information on the position of the car, information on the air conditioner status, information on the illumination, information on the brake switch, information on the parking brake switch, information on the turn signal of the turn signal, state of the belt on the driver seat, etc. Can be mentioned. Although stored in the internal storage unit, the control unit 24 distributes the input in-vehicle information to a plurality of channels of the communication unit 23 and outputs it. Therefore, the internal storage unit may basically have a function of temporarily storing. Therefore, the in-vehicle information communication device 20 does not need a nonvolatile storage element such as SD, SDD, or HDD, and the in-vehicle information communication device 20 can be made compact and inexpensive.

  Further, Bluetooth (registered trademark) is used as the communication unit 23, and a plurality of channels, for example, up to 7 channels are used. The in-vehicle information is not semi-permanently stored in the in-vehicle information communication device 20 but is transferred to the notebook computer or tablet as the mobile computer 13 by short-range wireless communication. By performing the transfer using a plurality of channels, the in-vehicle information to be transferred to the control unit 24 does not enter a waiting state, and is sequentially transferred to the mobile computer 13 by the communication unit 23 in the order of input.

  The control unit 24 distributes the in-vehicle information to each channel of the communication unit 23 by the following flow, for example. The control unit 24 temporarily accumulates in-vehicle information sequentially input from the first connection unit 21 and the second connection unit 22. The in-vehicle information temporarily accumulated is transferred to each channel in order from the first channel of the communication unit 23. The first in-vehicle information is transferred to the first channel, and the second in-vehicle information is transferred to the second channel.

  The in-vehicle information distributed processing by the control unit 24 will be specifically described. The control unit 24 monitors the communication state of each communication unit 23 and distributes information while grasping the transmission completion state of each communication unit 23. For example, when the control unit 24 distributes certain information to the communication unit 23b, if the communication unit 23b is not in a transmittable state, the communication unit 23b is in a transmittable state, for example, the communication unit 23c that is the next channel Send information. Thereby, accumulation of data in the control unit 24 is prevented. If the communication unit 23b does not return to the transmittable state for a certain period of time, it is determined that a communication failure has occurred in the communication unit 23b, and the data immediately before being transferred to the communication unit 23b is again in a communication-ready state. To the communication unit 23x.

  Since the control unit 24 performs such control, the information transferred to the communication unit 13a of the mobile computer 13 shown in FIG. 1 is rearranged based on the date / time information regardless of the arrival order, and is lost due to poor communication. To prevent. In the above example, the communication unit 23b in the communication failure state is forcibly restarted by the control unit 24 to enter the connection standby state. In response to this, the communication unit 13a of the mobile computer 13 automatically performs reconnection.

  Here, when in-vehicle information is transmitted from the in-vehicle information communication apparatus 20 to the mobile computer 13, it is preferable to use Bluetooth (registered trademark). Bluetooth (registered trademark) is a wireless communication standard that has been repeatedly improved for mobile and portable devices, and has lower power consumption and smaller packet size than other wireless communication means such as WiFi. Since the in-vehicle information is detection information of sensors provided in each part of the automobile, judgment results in the ECU, operation information, and the like, the information amount of each in-vehicle information is relatively small, and Bluetooth (registered trademark) is one packet. Suitable for information communication with a small amount of information.

  The in-vehicle information communication device 20 can be used not only by automobile users but also by automobiles and parts manufacturers. Conventionally, when designing and testing an automobile before sales, wiring is pulled from OBDII, a large-scale test device is brought into the automobile, data is accumulated, and analysis is performed at another place after the test run. . This interferes with the test run and also deteriorates workability. The in-vehicle information communication apparatus 20 according to the embodiment of the present invention can solve such a problem and perform analysis from the start of the test run. Further, since the CAN information is obtained immediately after the start of the running test, for example, it is possible to prevent the test from being re-executed due to the fact that some connections in the vehicle have not been made.

  The communication unit 23 establishes a connection with the communication unit 13a of the personal computer 13 corresponding to the number of channels. The connection between the communication unit 23 and the communication unit 13a is distributed to a plurality of channels according to the amount of data per unit time communicated from the in-vehicle communication device 20 to the mobile computer 13. That is, when the amount of data per unit transmitted to the in-vehicle communication device 20 is small, only one channel is used and not distributed to a plurality of channels.

Table 1 is a table showing data transmission rates when the transmission rates of the CAN bus connected to the first connection unit 21 and the second connection unit 22 are 1 Mbps and 500 kbps, and when both are 1 Mbps. For example, if the transmission speeds of the CAN buses connected to the first connection unit 21 and the second connection unit 22 are 1 Mbps and 500 Mbps, respectively, the transmission time of 8 bytes of data at each transmission rate is 111 μs. 222 μsec, the data amount per 1 ms is 432 bits on the assumption that the bus occupancy is 50%. If each CAN bus connected to the first connection unit 21 and the second connection unit 22 is 1 Mbits, the data amount per 1 msec is 577 bits.

Table 2 shows the data transmission speed in each channel number when the standard of Bluetooth (registered trademark) 2.0 + EDR is adopted as the communication unit 23 and the effective speed is 100 kbps.

When the standard of Bluetooth (registered trademark) 2.0 + EDR is adopted as the communication unit 23 from the value of the data amount per 1 msec transmitted from the in-vehicle network 11 and the sensor system 12 per msec shown in Table 2, 5 It can be seen that if there are 6 or 6 channels, the data can be transferred to the mobile computer 13 without overflowing.
Note that even though Bluetooth (registered trademark) is not a standard of Bluetooth (registered trademark) 2.0 + EDR, when the amount of in-vehicle data increases in the future, Bluetooth (registered trademark) 3.0 or Bluetooth (registered trademark) 4.0 will be supported. You can also

  Next, a method for communicating CAN information as in-vehicle information by the in-vehicle information communication device 20 according to the first embodiment of the present invention will be described. FIG. 3 schematically shows the communication status of CAN information by the in-vehicle information communication method 20, where (a) schematically shows input data, and (b) schematically shows the transmission distribution status from the control unit 24 to the communication unit 23. Show.

  As illustrated in FIG. 3A, information “CAN0” is sequentially input from the first connection unit 21, and information “CAN1” is sequentially input from the second connection unit 22. Each of “CAN0” and “CAN1” is composed of an identifier ID and Data. The header, footer, etc. necessary for the communication protocol are not shown. For each time series, the time is input from the first connection unit 21 and the second connection unit 22 in unit time (in the figure, the unit time is “1”).

  As shown in FIG. 3B, the control unit 24 temporarily stores the date and time information input via the first connection unit 21 and the second connection unit 22. As illustrated, “Time 1”, “Time 2”, and the like are date and time information, and “CAN 0” and “CAN 1” are indexes indicating whether the first connection unit 21 or the second connection unit 22 is input. “ID1” and “ID2” are sensor identifiers, and “Data1” and “Data2” are sensor data itself.

  The CAN information temporarily stored in the control unit 24 is transmitted to the mobile computer 13 by allocating transmission data for each Bluetooth (registered trademark) channel. Here, BT is a Bluetooth (registered trademark) module.

  Thus, in the in-vehicle information communication device 20, the in-vehicle information from the in-vehicle network system 11 is input from the first connection unit 21, and the in-vehicle information from the inspection system 12 is input from the second connection unit 22. In the control unit 24, date and time information is attached to the in-vehicle information input from the first connection unit 21 and the second connection unit 22, distributed to each channel of the communication unit 23, distributed, and transferred to the mobile computer 13. At that time, date information is attached to each in-vehicle information. As a result, information can be transferred in a distributed manner to the channels, and the transfer order at that time need not be the input order, and only information that could not be transferred due to poor communication or the like can be retransmitted. In addition, since the communication unit 23 distributes the data using a plurality of channels and transfers the data to the mobile computer 13, the in-vehicle information is hardly accumulated in the control unit 24. Therefore, not only can in-vehicle information increase in the future, but also it can be transferred to the mobile computer 13 while ensuring real-time performance.

  In the first embodiment of the present invention, since the communication unit 23 has a plurality of channels, the channel temporarily communicates for some reason, such as when wireless communication is performed using only one channel. No data overflows from the buffer when it becomes bad or impossible. That is, as in the first embodiment of the present invention, data is distributed to a plurality of channels, and the communication state of each channel is ensured. In addition to avoiding spillage, data can be transferred in real time.

  Unlike the first embodiment of the present invention, it is also conceivable to store untransferred data in a memory using only one channel and transmit the untransferred data again after the communication state returns to normal. However, in this case, as in the embodiment of the present invention, it is not possible to enjoy the advantage of communicating in-vehicle information while ensuring real-time performance.

  As described above, according to the first embodiment of the present invention, the in-vehicle information can be transferred in real time, and even if the in-vehicle information increases rapidly, it can be dealt with. Therefore, in-vehicle information can be transmitted to the outside of the vehicle accurately and reliably in response to the increasing demand and necessity of data management outside the vehicle such as the recent cloud. Therefore, all the in-vehicle information including various sensor information and operation information transmitted to the CAN bus can be transmitted to an external computer such as the mobile computer 13 or the server device 14 without being missed.

  In the in-vehicle information utilization network system 10 shown in FIG. 1, not only the in-vehicle information is used by taking out the in-vehicle information from the in-vehicle network system 11 and the inspection system 12 and transferring it to the server device 14, but also using the mobile computer 13. The in-vehicle network system 11 and the inspection system 12 can be controlled by the in-vehicle information communication device 20.

  For example, the in-vehicle information communication apparatus 20 can receive a command from the mobile computer 13 by the communication unit 23 and transmit the command to the in-vehicle network system 11 and the system 12. As an example, devices mounted on the vehicle such as commands to the in-vehicle network system 11, lighting of warning signals, and navigation operations can be operated via the in-vehicle information communication device 20. As another example, a drive device that has a built-in servo motor and can receive CAN information can be connected to the second connection unit 22 to operate the drive device. Examples of driving devices include navigation.

  Next, an example of a method for using in-vehicle information by the in-vehicle information utilization network system 10 according to the first embodiment of the present invention will be described. For example, when a user drives a vehicle, the vehicle information communication network 20 shown in FIG. 1 transmits CAN information transmitted to the CAN bus in the vehicle-mounted network system 11 via the first connection unit 21. To the mobile computer 13. The CAN information transmitted to the mobile computer 13 is uploaded to the server device 14 via the router 16. In the server device 14, the uploaded CAN information is stored in the database 14c by the control unit 14b.

FIG. 4 is a configuration diagram of the in-vehicle information utilization network system 50 including the in-vehicle information communication device 60 according to the second embodiment of the present invention. Since the in-vehicle information communication device 60 transmits and receives in-vehicle information and supplies a battery, the in-vehicle information communication device 60 may be referred to as an “in-vehicle relay device”.

  An in-vehicle information utilization network system (hereinafter abbreviated as “network system”) 50 includes an in-vehicle information communication device 60, an in-vehicle network system 70 mounted on a vehicle body 55 such as an automobile as standard equipment, and an external communication terminal. The apparatus 80 is comprised. The external communication terminal device 80 can be connected to the cloud as the server device 90. Here, as the external communication terminal device 80, for example, various client terminals such as a smartphone and other mobile phones are applicable.

  As shown in FIG. 5, the in-vehicle network system 70 includes a vehicle powertrain system 71a, a body control system 71b that controls doors, mirrors, and the like, a safety system 71c that controls airbags, and a VICS as shown in FIG. (Registered trademark) navigation system, multimedia system 71d for controlling audio, fault diagnosis system 71e in which on-board fault diagnosis device (ODB: On Board Diagnostic) is connected to a bus such as CAN bus, etc. are connected via in-vehicle LAN Configured. As the in-vehicle LAN, a CAN bus or other network is used, and a sensor is attached to each system. Therefore, CAN (Control Area Network) data including sensor data is transmitted to the CAN bus as in-vehicle data.

  The in-vehicle network system 70 includes a port 72, specifically, an OBDII port, and an external connection terminal is connected to the port 72. As described with reference to FIG. Can be taken out. The in-vehicle data is information flowing on the in-vehicle network, and includes information output from various in-vehicle sensors including switches attached to the automobile. Examples of the in-vehicle sensor include various sensors attached to an engine, wheels, an accelerator pedal, a brake pedal, and the like, a drive mode switch and a door open / close switch. As an example of in-vehicle data, there are various data relating to accelerator operation, brake operation, steering operation, etc. in addition to vehicle speed, travel distance, drive mode, and fuel consumption. As described above, the in-vehicle sensor and the in-vehicle data are the same as those in the first embodiment.

  The in-vehicle network system 70 includes an automatic control ECU 73. As shown in FIG. 5, the automatic control ECU 73 causes a powertrain system 71a such as an engine, a steering, and an ABS, an air conditioner, a switch, an air conditioner, a door, and a lamp. System control system 71b, safety system 71c such as sensor and squeeze, multimedia system 71d such as audio and navigation system, failure diagnosis system 71e such as CAN bus and diagnostic tool, etc. To control. Further, the in-vehicle network system 70 includes a battery 74 as a power source. Electric power is supplied from the battery 74 to each part of the vehicle through various wirings not shown in FIG. In addition, electric power generated when the engine, the brake, or the like is operating is stored in the battery 74.

  The in-vehicle information communication device 60 according to the second embodiment of the present invention includes a first connection unit 61, a data processing unit 62, an adjustment unit 63, and a second connection unit 64, as shown in FIG. These will be described in detail below.

  The first connection unit 61 has a connection function to be connected to the bus of the in-vehicle network system 70, and by inputting the in-vehicle data from the in-vehicle network system 70 by connecting the first connection unit 61 to the port 72 of the bus. And DC power supply from the battery 74 can be received.

  The data processing unit 62 includes a CPU and a storage unit such as a flash memory. Various application programs are stored in the storage unit and read and executed by the CPU, whereby the first connection unit 61 is connected from the in-vehicle network system 70. Receives in-vehicle data input via and performs predetermined data processing. By providing the driver 62 a between the first connection unit 61 and the data processing unit 62, in-vehicle data on the bus of the in-vehicle network system 60 can be accepted.

  The adjustment unit 63 adjusts the power supplied from the battery 74 in the in-vehicle network system 60 via the first connection unit 61. Since the power supplied from the battery 74 is not accepted by the external communication terminal device 80 as it is, it is adjusted by the adjustment unit 63 and supplied to the external communication terminal device 80. For example, the direct current voltage is converted into a predetermined voltage, for example, 5V, 3.3V, or the like.

  The second connection part 64 has an insertion receiving part. When the terminal of the cable 81 is inserted into the insertion receiving part, the in-vehicle information communication device 60 and the external communication terminal device 80 are connected via the cable 81. Connected.

  Each of the data processing unit 62 and the second connection unit 64 has a HOST function. When the USB terminal is connected to the second connection unit 64, for example, the data processing unit 62 is connected to the external communication terminal via the cable 81. Recognizing the device 80, the in-vehicle information communication device 60 charges the external communication terminal device 80 via the second connection unit 64 and the cable 81.

  A switch 65 is interposed between the data processing unit 62, the adjustment unit 63, and the second connection unit 64. By turning on the switch 65, vehicle-mounted information is controlled under the control of the data processing unit 62. Power can be supplied to the external communication terminal device 80 along with the power supply to the communication device 60.

  The ON / OFF of the switch 65 will be described. The data processing unit 62 receives input of in-vehicle data via the first connection unit 61, monitors the ON / OFF state of the vehicle engine based on the in-vehicle data related to the input, and the vehicle engine is OFF Then, the power supply from the adjustment unit 63 to the external communication terminal device 80 is stopped. By executing the program stored in the data processing unit 62, the ON / OFF control of the switch 65 is performed.

  FIG. 7 is a flowchart regarding ON / OFF of the switch 65. If the vehicle ignition (ignition device) is in the ON state, the CAN signal flows as in-vehicle data in the in-vehicle network system 70, and if the ignition is in the OFF state, the CAN signal does not flow in the in-vehicle network system. Therefore, when the in-vehicle data is input from the first connection unit 61 and the driver 62a, the data processing unit 62 starts measuring the CAN signal (step 1) and turns the switch 65 from OFF to ON. The CAN signal is continuously measured (step 3) until the input of the in-vehicle data is stopped (not in step 2). On the other hand, when the input of in-vehicle data is stopped, the sleep state is entered (step 4). In this state, the switch 65 is turned from ON to OFF. Thereafter, when a CAN signal is newly input as in-vehicle data (“Yes” in Step 5), the switch 65 is turned from OFF to ON, and the process returns to Step 1.

  In this way, by linking the switch 65 to ON / OFF of the engine, power supply from the in-vehicle battery 74 to the in-vehicle information communication device 60 is started and stopped, and charging to the external communication terminal device 80 is performed. Stop or stop.

  The data processing unit 72 stores application programs in the following procedure. For example, information on the vehicle type, type, and other vehicles is registered from the external communication terminal device 80 or another terminal device (not shown) to the server device 90 shown in FIG. Then, various application programs are downloaded from the cloud as the server device 90 to the data processing unit 62 of the in-vehicle information communication device 60 via the external communication terminal device 80 and further via the cable 81.

  The application program transfers only necessary data out of the CAN information as in-vehicle data that differs depending on the vehicle type, model, etc., from the in-vehicle information communication device 60 to the external communication device 80 or to the cloud as the server device 90. Therefore, it is possible to extract necessary in-vehicle data from the in-vehicle network system 70 when necessary. That is, the data processing device 62 selects necessary data from the CAN information according to the vehicle type or model. Furthermore, since the sampling function can change the sampling frequency for data extraction from the in-vehicle network system 70 to the driver 62a by the filtering function, the data processing unit 62 is not burdened. Therefore, unnecessary data is not transferred to the external communication terminal device 80 that is the transfer destination, and thus no load is applied to the external communication terminal device 80.

  In this way, the in-vehicle data extracted from the in-vehicle network system 70 is transferred to the external communication terminal device 80 via the in-vehicle information communication device 60 and further uploaded to the cloud. In-vehicle data uploaded to the cloud is subjected to data mining and various statistical processes, and is used for driver behavior analysis and various marketing.

  Furthermore, in a preferred embodiment, as shown in FIG. 6, the in-vehicle information communication device 60 includes one or more sensors 66. Examples of the type of sensor 66 include an acceleration sensor and a gyro sensor. It is also possible to detect the posture of the vehicle body statically in two dimensions or three dimensions using an acceleration sensor, detect the posture of the vehicle body dynamically using a gyro sensor, and detect the posture by combining both sensors. A GPS sensor, a direction sensor, and an angular velocity sensor may be used for static vehicle body posture detection. The data processing unit 62 obtains the vehicle behavior by receiving input of data from these sensors 66 and performing analysis and the like.

  Information about the obtained vehicle behavior is processed along the following flow and used to control the vehicle attitude. For example, the control data of the vehicle attitude may be generated based on the obtained result in the data processing unit 62. For example, the data processing unit 62 only obtains the vehicle behavior, transmits the obtained result to the external communication terminal device 80 connected to the second connection unit 64, and performs application program processing in the external communication terminal device 80. Vehicle attitude control data may be obtained. For example, the external communication terminal device 80 transfers the result as information on the vehicle behavior from the in-vehicle information communication device 60 to another device, and generates control data for the vehicle attitude in the other device. Here, as another device, a so-called unit, for example, a control controller 75 or an automatic control ECU 73 described with reference to FIG.

  The control data thus obtained is transmitted from the data processing unit 62 of the in-vehicle information communication device 60 to the in-vehicle network 70 via the first connection unit 61, and the automatic control ECU 73 issues a command to perform desired control. Is made. Alternatively, as will be described with reference to FIGS. 8 and 9, the obtained control data is transmitted to the automatic control ECU 73 via the control controller 75 as necessary, and the automatic control ECU 73 issues a command. Desired control is performed.

  The data processing unit 62 analyzes the data of one or more sensors 66 to detect a driver's habit, or is in a dangerous driving state such as distracting driving or driving with fatigue. By detecting the vehicle behavior, the vehicle behavior can be obtained. By analyzing the data from the sensor 66, for example, when the vehicle wobble is detected, it is determined that the vehicle is dozing. When sudden acceleration, oblique line change, sudden deceleration, or the like is detected, it is determined that the vehicle is overtaking. If sudden acceleration, sudden deceleration, cornering at a high speed, or a steep slope is detected, it is determined that the vehicle is running violently. At that time, for example, using the data from the GPS sensor and the map information stored in the external communication terminal device 80, the vehicle position may be analyzed together with the map information to detect the behavior of the vehicle. . It is also possible to grasp the driving situation of the driver by taking into account the driving situation of the vehicle depending on whether the vehicle position is a road condition such as the type of a road such as an expressway or a general road in light of the map information. Further, by uploading the data of these sensors to the server device 90 via the external communication terminal device 30, it is also possible to use it for analysis of the driving state and the driver's psychological state.

  Further, the data processing unit 62 may process the in-vehicle data acquired via the first connection unit 61 as follows. The processed result is used to generate control data for controlling the vehicle. There are several possible modes of processing. As a first example, the data processing unit 62 transmits the processing result to the in-vehicle network system 70 via the first control unit 61. Thereby, control data is produced | generated based on a process result in automatic control ECU73 of the vehicle-mounted network system 70. FIG. As a second example, the in-vehicle information communication device 60 transmits the processing result to the external communication terminal device 80 connected to the second connection unit 64. Thus, control data for controlling the vehicle is generated in response to the processing result in the external communication terminal device 80, and the control data is transmitted to the automatic control ECU 73 directly or via another device, so-called unit. . As a third example, control data is not generated in the external communication terminal device 80, and the external communication terminal device 80 transfers the control data to, for example, the control controller 75 shown in FIG. It is transmitted to the control ECU 73. As a fourth example, the in-vehicle information communication device 60 transmits the processing result to the automatic control ECU 73 directly or via the external communication terminal device 80 or the like, and the automatic control ECU 73 generates control data based on the processing result. The Specific examples are given below.

In FIG. 8, the automatic control ECU 73 is provided in the in-vehicle network system 70 of FIG. 5, and comprehensively and automatically controls the system 70 to control the systems 71 a to 71 e shown in FIG. 4.

  As described above, the vehicle behavior is obtained by the data processing unit 62, and the obtained result or control data is transmitted to the automatic control ECU 73 shown in FIGS. 5 and 8 via the external communication terminal device 80. Further, control information is transmitted to the control controller 75 by short-range radio such as WiFi or Bluetooth (registered trademark), and a signal is transmitted to the automatic control ECU 73 as CAN information. Then, the automatic control ECU 73 controls the steering, the accelerator, the brake, the shift, the lights, etc., for example, brings the car to the right side of the road and stops it safely.

  FIG. 9 is a system configuration diagram using the in-vehicle information communication device 60 according to the second embodiment of the present invention and is a diagram showing an aspect different from FIG. In FIG. 9, an application program related to the function of the controller 75 shown in FIG. 8 is incorporated in the external communication terminal device 80 by downloading it from the server device 90, and the external communication terminal device 80 sends WiFi to the automatic control ECU 73. Results and control data obtained by the data processing unit 62 are transmitted by short-range wireless communication such as Bluetooth or Bluetooth (registered trademark). In response to this, the automatic control ECU 73 generates control data from the received vehicle behavior result, or processes the received control data as necessary to control the steering, accelerator, brake, shift, and lights. For example, the vehicle is brought to the right side of the road and stopped safely.

  In this way, by monitoring the movement of the vehicle with the sensor 66 or in-vehicle data, for example, even if the driving is disturbed due to sudden illness during driving, the system detects and promptly issues a hazard. You can stop.

  As described above, the in-vehicle data is transferred from the in-vehicle information communication device 60 to the external communication terminal device 80.

Then, the following can be realized. The in-vehicle information communication device 60 transfers the vehicle speed data to the external communication terminal device 80 as the in-vehicle data output from the in-vehicle network system 70. Then, the in-vehicle information communication device 60 can determine that the vehicle has started traveling at a speed higher than the speed specified in the application program, and the external communication terminal device 80 sends the control controller 75 with WiFi or Bluetooth (registered trademark). The determination result is notified and transferred to the automatic control ECU 73 via the CAN bus. Then, the door can be automatically locked. Note that the external communication terminal device 80 may notify the automatic control ECU 73 directly by WiFi or Bluetooth (registered trademark).

  In addition, drivers who are away from the vehicle, using an external communication terminal device that they have separately, can check whether the door is locked or open / close the window, automatically lock the door, open / close the window, etc. Of the application programs that are programmed to control the above, all or a necessary part may be downloaded to each external communication terminal device 80 or another external communication terminal device.

  As an example, the driver who is away from the vehicle may receive the current status of the vehicle from the external communication terminal device that is actually owned separately from the external communication terminal device 80 left in the vehicle to the external communication terminal device 80 in the vehicle. A command is issued to inform you. Then, since the external communication terminal device 80 in the vehicle has the latest in-vehicle data, the data on the current status of the vehicle is read from the stored data, and the data on the latest status is read from another external communication terminal device. Send.

  Through such a series of flows, the external communication terminal device actually possessed by the driver presents the driver with data transmitted from the external communication terminal device 80 in the vehicle, so the driver locks the door, for example. Then, a command for operating the air conditioner or the like is sent from the external communication terminal device currently possessed to the external communication terminal device 80 in the vehicle. Then, various remote controls, such as a door lock of a vehicle and the start of an air-conditioner operation, can be performed. Here, the external communication terminal device 80 in the vehicle and the external communication terminal device actually owned by the driver may pass through a wireless LAN such as WiFi.
