[0001] The present disclosure relates to a technique for collecting vehicle data and transmitting it to a server. [Background technology]

[0003] [Patent Document 1] JP 2018-060520 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, after detailed consideration by the inventors, a problem was found in that when collecting vehicle data from a single vehicle equipped with multiple different communication interfaces, it is necessary to create a device that collects vehicle data according to the communication interfaces installed in the vehicle.
[0005] Furthermore, when collecting vehicle data from different vehicles using different communication interfaces, a problem has been found in that it is necessary to use different devices for collecting vehicle data in accordance with the vehicles having different communication interfaces.
[0006] One aspect of the present disclosure is to provide a technique for standardizing and collecting vehicle data having different communication interfaces. [Means for solving the problem]
[0007] One aspect of the present disclosure is a data collection device (100) that collects vehicle data and transmits it to a server (4), and includes an arrangement conversion unit (110, 120, 130), a data conversion unit (160, S402 to S406, S410 to S414, S418 to S422), and a communication unit (190).
[0008] The layout conversion unit converts the vehicle data supplied from the data supply device (30) in a signal layout corresponding to the communication interface into a common signal layout. The data conversion unit converts the vehicle data of the communication protocol corresponding to the communication interface converted into the common signal layout by the layout conversion unit into data in a common format. The communication unit transmits the vehicle data converted into data in the common format by the data conversion unit to a server.
[0009] Another aspect of the present disclosure is a data collection system (20) that collects vehicle data and transmits it to a server (4), comprising a data supply device (30) and a data collection device (100).
[0010] The data supplying device includes a gateway (50) that supplies vehicle data from a vehicle network, and connectors (70-74) that supply the vehicle data from the gateway in a signal arrangement according to the communication interface.
[0011] The data collection device includes a layout conversion unit (110, 120, 130), a data conversion unit (160, S402 to S406, S410 to S414, S418 to S422), a connector (152), and a communication unit (190).
[0012] The layout conversion unit converts the signal layout of the vehicle data supplied by the data supply device into a common signal layout. The data conversion unit converts the vehicle data of the communication protocol corresponding to the communication interface converted into the common signal layout by the layout conversion unit into data in the common format.
[0013] The data conversion unit obtains, from the connector, the vehicle data that has been converted into a common signal arrangement by the arrangement conversion unit. The communication unit transmits the vehicle data, which has been converted into data in the common format by the data conversion unit, to the server.
[0014] Furthermore, the layout conversion unit includes a common connector (152) that connects to the connector from which the data conversion unit acquires vehicle data, a supply side connector (112, 122, 132) that connects to the connector of the data supply device, and a cable (114, 124, 134) that connects the common connector and the supply side connector and converts the signal layout of the supply side connector into a common signal layout of the common connector.
[0015] With this configuration, even if vehicle data with different communication interfaces is supplied from a data supply device of one vehicle or from data supply devices of multiple vehicles, the vehicle data is converted into data in a common format by the common data collection device, so there is no need to prepare a different data collection device for each communication interface.
[0016] In the data collection system, the layout conversion unit connects the connector of the data supply device to the connector through which the data conversion unit of the data collection device obtains vehicle data, making it possible to easily convert vehicle data supplied via different communication interfaces into data in a common format.
[0017] If the communication interface of the vehicle data supplied from the data supply device is different and the signal arrangement of the connector of the data supply device is different, a layout conversion unit that matches the communication interface may be prepared. Also, if the communication protocol is different, a data conversion unit that matches the communication interface may be prepared.
[0018] Since the vehicle data supplied via the different communication interfaces is converted into vehicle data in a common format, the server can easily process the vehicle data converted into the common format. [Brief description of the drawings]

[0020] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. [1. Configuration] As shown in FIG. 1, a data management system 2 of this embodiment includes a server 4, a wireless communication network 6, and a plurality of data collection systems 20.
[0021] The server 4 communicates data with a plurality of data collection systems 20 via the wireless communication network 6, and manages the traveling of the vehicle 10 based on the vehicle data collected from the data collection systems 20.
[0022] The data collection system 20 is mounted on a vehicle 10 and includes a data supplying device 30 and a data collecting device 100 . 2, the data supplying device 30 includes a plurality of ECUs 40 mounted on the vehicle 10, a gateway 50, an FMS control unit 60, an OBD2 connector 70, an FMS connector 72, and a CAN connector 74. OBD is an abbreviation for On Board Diagnostics, FMS is an abbreviation for Fleet Management System, and CAN is an abbreviation for Controller Area Network. CAN is a registered trademark.
[0023] The ECUs 40 communicate with each other for each control group using the CAN protocol, for example, and control the running of the vehicle 10. The gateway 50 acquires vehicle data, such as control values for controlling the vehicle 10 and detection values of various sensors installed in the vehicle 10, from the ECU 40. The gateway 50 transmits the vehicle data acquired from the ECU 40 to the OBD2 connector 70 and the FMS connector 72 via their respective communication interfaces.
[0024] In this embodiment, the communication interface means at least one of the standards for hardware and software in communication, and the communication protocol means at least one of the procedures and data format in communication. The FMS control unit 60 provides some of the vehicle data collected from the CAN as data in the FMS standard format.
[0025] The OBD2 connector 70 and the FMS connector 72 are connectors that are installed on the vehicle 10 as standard. Typically, the CAN connector 74 is not mounted on the vehicle 10. The CAN connector 74 is installed to connect to a vehicle network on the ECU 40 side rather than the gateway 50 and acquire desired vehicle data, for example, when vehicle data that cannot be acquired through the communication interface between the OBD2 connector 70 and the FMS connector 72 is required.
[0026] As shown in FIG. 3, the data collection device 100 includes conversion adapters 110, 120, and 130 and a data processing device 150. The conversion adapter 110 includes an OBD2 connector 112, a cable 114, and a common connector 140. The conversion adapter 120 includes an FMS connector 122, a cable 124, and a common connector 140. The conversion adapter 130 includes a CAN connector 132, a cable 134, and a common connector 140. The common connectors 140 of the conversion adapters 110, 120, and 130 each have the same signal arrangement.
[0027] The OBD2 connector 112 is connected to the OBD2 connector 70 of the data providing device 30. The FMS connector 122 is connected to the FMS connector 72 of the data providing device 30. The CAN connector 132 is connected to the CAN connector 74 of the data providing device 30.
[0028] The common connectors 140 of the conversion adapters 110 , 120 , 130 are each connected to a common connector 152 of the data processing device 150 . Cable 114 connects OBD2 connector 112 and common connector 140 , cable 124 connects FMS connector 122 and common connector 140 , and cable 134 connects CAN connector 132 and common connector 140 .
[0029] As shown in FIG. 4, the OBD2 conversion adapter 110 converts a signal arrangement corresponding to the OBD2 interface indicated by the pin numbers of the OBD2 connector 112 into a common signal arrangement of a common connector 140 using a cable 114.
[0030] As shown in FIG. 5, the conversion adapter 120 for the FMS converts, via a cable 124 , a signal arrangement corresponding to the interface of the FMS indicated by the pin numbers of the FMS connector 122 into a common signal arrangement of the common connector 140 .
[0031] As shown in FIG. 6, a conversion adapter 130 for CAN converts a signal arrangement corresponding to the CAN interface indicated by the pin numbers of a CAN connector 132 into a common signal arrangement of a common connector 140 by a cable 134 .
[0032] Furthermore, the power supply (+) or 12V, GND or 12VGND, CAN1_H or CAN_H, and CAN1_L or CAN_L are all common and the same signals in the OBD2 connector 112, the FMS connector 122, and the CAN connector 132. These signals are converted into a single signal by cables 114, 124, and 134, and their signal arrangement is converted to power supply (+) at pin number 5, GND at pin number 6, CAN1_H at pin number 7, and CAN1_L at pin number 8 of the common connector 140. The data processing device 150 of the data collection device 100 is supplied with power from the data supply device 30 via a power pin of the common connector 152 .
[0033] 3, when multiple common connectors 152 are installed for multiple communication interfaces, wiring is performed so that power is supplied from the power pin of only one of the common connectors 152. This is to prevent power from being supplied to the data processing device 150 from the power pins of multiple common connectors 152 in a duplicated manner.
[0034] Therefore, in order to supply power from the data supply device 30 to the data processing device 150, it is necessary to connect any one of the conversion adapters 110, 120, 130 to the common connector 152 at the position where the power is supplied.
[0035] 7, the signal values of pin numbers 1 to 4 of common connector 140, which represent the interface ID, are set to the signal values of the corresponding communication interfaces for each of conversion adapters 110, 120, and 130. ID represents an identifier. For example, if the signal value of the interface ID is 0b0001, it means a CAN signal, and if the signal value is 0b0010, it means an OBD2 signal.
[0036] The data processing device 150 includes a common connector 152 , a data conversion unit 160 , a data storage unit 170 , a data access unit 180 , and a communication unit 190 . The data processing device 150 is equipped with a microcomputer having, for example, a CPU, a ROM, a RAM, a flash memory, etc. (not shown). The CPU of the data processing device 150 executes a program stored in the ROM or the flash memory, thereby performing a data collection process (described later).
[0037] The common connector 152 is connected to the common connector 140 of the conversion adapters 110, 120, and 130. The signal arrangement of the common connector 152 corresponds to the signal arrangement of the common connector 140 of the conversion adapters 110, 120, and 130.
[0038] The data conversion unit 160 includes an interface identification unit 162 and a format conversion unit 164. The data conversion units 160 are configured independently for each communication interface, the number of which corresponds to the communication interfaces supported by the data processing device 150. Each data conversion unit 160 acquires a signal from one of the common connectors 152.
[0039] The interface identification unit 162 identifies the communication interface of the vehicle data acquired from the common connector 152 based on the signal value of the interface ID of the common connector 152 . The format conversion unit 164 converts the vehicle data acquired from the common connector 152 into data in the common format shown in FIG. 8 in accordance with the communication interface identified by the interface identification unit 162.
[0040] The data ID in the common format indicates what the data represents, for example, engine speed, vehicle speed, position, remaining fuel, remaining battery charge, diagnostic code, etc.
[0041] The data value of the common format is, for example, a numerical value expressed in binary, or if it is a character, it is expressed in binary in UTF-8 format. If the data value is a numerical value, the unit is preset according to the data ID. For example, if the data ID represents the vehicle speed, the unit is km / h.
[0042] Below, the process in which the format conversion unit 164 converts the vehicle data acquired from each of the common connectors 152 based on the communication protocol corresponding to the communication interface into data in the common format shown in Figure 8 will be described using OBD2 and CAN as examples.
[0043] (1)OBD2 The OBD2 format conversion unit 164 of the data collection device 100 transmits a message requesting vehicle data to the data supplying device 30 via the OBD2 conversion adapter 110. The OBD2 vehicle data request message is transmitted periodically, or is transmitted via the communication unit 190 when requested from outside the vehicle 10.
[0044] For example, when collecting vehicle speed data as the vehicle data, the format conversion unit 164 transmits a request message for vehicle speed data to the data supplying device 30 from the common connector 152 via the conversion adapter 110 for OBD2. The signal arrangement of the request message for vehicle speed data is converted by the conversion adapter 110 from the common signal arrangement of the common connector 152 to the signal arrangement of the OBD2 connector 112 corresponding to the OBD2 interface.
[0045] 9, a vehicle data request message with CAN ID=0x7E0, SID=0x01, and Data ID=0x0D is transmitted to the data supply device 30 via CAN1_H and CAN1_L of the conversion adapter 110. CAN ID=0x7E0 specifies the engine ECU as the ECU to which the vehicle data is requested, SID=0x01 indicates the current data request as a diagnostic service, and Data ID=0x0D indicates that the requested data is vehicle speed.
[0046] In response to a request for vehicle speed data via OBD2, the data supplying device 30 transmits a response message with CAN ID=0x7E8, SID=0x41, and Data ID=0x0D to the data collecting device 100 via CAN1_H and CAN1_L of the conversion adapter 110. CAN ID=0x7E8 indicates a response from the engine ECU, SID=0x41 indicates that it is a response to the current data request, and Data ID=0x0D indicates that the response data is vehicle speed.
[0047] The signal arrangement of the response message of the vehicle speed data is converted by the conversion adapter 110 from the signal arrangement of the OBD2 connector 112 corresponding to the OBD2 interface to the common signal arrangement of the common connector 152 .
[0048] The format conversion unit 164 acquires the response message of the OBD2 communication protocol that has been converted into a common signal arrangement in the common connector 152. Then, the format conversion unit 164 refers to the conversion table based on the CAN ID=0x7E8, SID=0x41, and Data ID=0x0D of the response message, and acquires resolution=1 and offset=0.
[0049] Then, the format conversion unit 164 extracts the Data portion from the response message, multiplies it by a resolution of 1, and adds an offset of 0 to generate vehicle speed data. For example, when the generated vehicle speed data is 30km / h, the format conversion unit 164 converts it into vehicle data in a common format as shown in Fig. 9, with a data ID of 0x01 and a data value of 30. The data ID of 0x01 indicates that the vehicle data is a vehicle speed.
[0050] (2)CAN For example, the data collecting device 100 acquires a message with CAN ID=0x123 from the data supplying device 30 via CAN1_H and CAN1_L of the conversion adapter 130. CAN ID=0x123 indicates that the message is from an ECU that transmits vehicle speed.
[0051] The signal arrangement of the vehicle speed data is converted by the conversion adapter 130 from the signal arrangement of the CAN connector 132 corresponding to the CAN interface to the common signal arrangement of the common connector 152 .
[0052] The format conversion unit 164 acquires the message of the CAN communication protocol that has been converted into a common signal arrangement in the common connector 152. Then, the format conversion unit 164 refers to the conversion table based on the CAN ID=0x123 of the acquired message, and acquires position=1.0, DLC=16 bit, resolution=0.01, and offset=0.
[0053] The format conversion unit 164 extracts DLC=16 bit data from position=1.0 in the Data portion of the message, multiplies it by resolution=0.01, and adds offset=0 to generate vehicle speed data.
[0054] For example, if the generated vehicle speed data is 30 km / h, the format conversion unit 164 converts it into vehicle data in a common format as shown in Fig. 10, with a data ID of 0x01 and a data value of 30. The data ID of 0x01 indicates that the vehicle data is a vehicle speed.
[0055] The vehicle data converted into the common format by the data conversion unit 160 is stored in a data storage unit 170 configured with a memory such as a RAM or a flash memory. The data stored in the data storage unit 170 is rewritten each time it is stored, or is rewritten in sequence starting from the oldest data in a ring buffer format.
[0056] Since the vehicle data stored in the data storage unit 170 is in a common format, it is accessed by the data access unit 180 in a common access method, rather than for each communication interface when the data is supplied from the data supply device 30 .
[0057] The communication unit 190 transmits to the server 4 the vehicle data accessed by the data access unit 180 in the common access method. [2. Processing] The data collection process executed by the data collection device 100 will be described with reference to the flowchart shown in Fig. 11. The program for executing the flowchart in Fig. 11 is stored in each data conversion unit 160 configured independently for each communication interface.
[0058] The flowchart shown in Fig. 11 is executed when the data processing device 150 is connected to the data supplying device 30 via at least one of the conversion adapters 110, 120, and 130 and is supplied with power from the data supplying device 30. Thereafter, the flowchart shown in Fig. 11 is executed by the data processing device 150 at predetermined time intervals.
[0059] In S400, the interface identifying unit 162 identifies the communication interface of the vehicle data acquired from the common connector 152 based on the interface ID indicated by the signal values of the pin numbers 1 to 4 of the common connector 152.
[0060] If the determination in S402 is No, that is, if the communication interface is not OBD2, the process proceeds to S410. If the determination in S402 is Yes, that is, if the communication interface is OBD2, in S402, the format conversion unit 164 acquires a data signal representing vehicle data from the common connector 152 based on the communication protocol corresponding to the identified communication interface.
[0061] In S406, the format conversion unit 164 converts the vehicle data acquired from the common connector 152 into data in a common format. In S408, the format conversion unit 408 updates the old vehicle data with the current vehicle data and stores the latest data.
[0062] If the determination in S410 is No, that is, if the communication interface is not an FMS, the process proceeds to S418. If the determination in S410 is Yes, that is, if the communication interface is FMS2, in S412 to S416, the format conversion unit 164 executes the processes in S404 to S408 described above, substituting FMS for OBD2.
[0063] If the determination in S418 is No, that is, if the communication interface is none of OBD2, FMS, and CAN, the process proceeds to S426. If the determination in S418 is Yes, that is, if the communication interface is CAN, in S420 to S414, the format conversion unit 164 executes the processes in S404 to S408 described above, substituting CAN for OBD2.
[0064] In S426, the format conversion unit 164 executes an appropriate process according to the interface ID indicated by the signal values of the pin numbers 1 to 4 of the common connector 152. For example, if the interface ID indicates a value indicating that none of the common connectors 142 of the conversion adapters 110, 120, and 130 is connected to the common connector 152, this process ends without doing anything.
[0065] Alternatively, if the interface ID indicated by the signal values of pin numbers 1 to 4 of the common connector 152 is different from a value expected in a normal case, the format conversion unit 164 notifies the vehicle 10 of the abnormality.
[0066] [3. Effects] According to the embodiment described above, the following effects can be obtained. (1) Vehicle data having different communication interfaces supplied from the data supply device 30 is converted by the conversion adapters 110, 120, 130 and the data conversion unit 160 into data in a common format as shown in (a) and (b) below.
[0067] (a) The conversion adapters 110, 120, and 130 convert the signal arrangement for each communication interface on the data supply device 30 side into a common signal arrangement based on the communication interface. (b) The data conversion unit 160 converts the vehicle data converted into the common signal arrangement into data in a common format based on a communication protocol corresponding to the communication interface.
[0068] As a result, by simply connecting the conversion adapters 110, 120, 130 to the data supply device 30 and the data processing device 150 having the data conversion unit 160, vehicle data having different communication interfaces can be easily converted into data in a common format.
[0069] Furthermore, even if vehicle data having different communication interfaces is supplied from the data supplying device 30 of one vehicle 10 or from the data supplying devices 30 of multiple vehicles 10, the vehicle data is converted into data in a common format by the common data collecting device 100. Therefore, it is not necessary to prepare a different data collecting device for each communication interface.
[0070] Since the vehicle data supplied via different communication interfaces is converted into vehicle data in a common format, the server 4 can easily process the vehicle data converted into the common format.
[0071] (2) When the data supply device 30 converts the signal arrangement of the vehicle data supplied according to the communication interface into a common signal arrangement, the signals common to each communication interface are arranged as one signal in the common signal arrangement. This makes it possible to minimize the number of signals in the common signal arrangement. As a result, the number of pins in the common connectors 140 and 152 can be reduced, and the common connectors 140 and 152 can be made smaller.
[0072] (3) Since power is supplied from the data supplying device 30 to the data processing device 150 of the data collecting device 100 via any one of the conversion adapters 110, 120, 130, there is no need to install a power supply in the data collecting device 100.
[0073] (4) It is not predetermined which of the conversion adapters 110, 120, and 130 of the communication interface will be connected to the common connector 152 of the data processing device 150. Therefore, an interface ID indicating the communication interface is set in the signals converted by the conversion adapters 110, 120, and 130 into a common signal arrangement in the common connector 152.
[0074] As a result, no matter which of the communication interfaces of conversion adapters 110, 120, and 130 is connected to common connector 152, data conversion unit 160 of data processing device 150 can identify the communication interface of the connected conversion adapter by the interface ID.
[0075] (5) The OBD2 connector 70 and the FMS connector 72 are normally installed in the vehicle 10. Therefore, when the data supplying device 30 uses OBD2 and FMS as communication interfaces for supplying vehicle data, it is not necessary to newly install the OBD2 connector 70 and the FMS connector 72 in the vehicle 10.
[0076] (6) By using CAN as a communication interface, the data collection device 100 acquires vehicle data directly from the network of the vehicle 10 rather than from the gateway 50, so that vehicle data that could not be acquired by OBD2 or FMS can be acquired.
[0077] In the embodiment described above, the conversion adapters 110, 120, and 130 correspond to the layout conversion units, and the OBD2 connector 112, the FMS connector 122, and the CAN connector 132 correspond to the supply side connectors.
[0078] Moreover, the processes of S402 to S406, S410 to S414, and S418 to S422 correspond to the processes of the data conversion unit. 5.
