Description

[Technical Field]

[0001] FIELD An embodiment of the present invention relates to a simulated test environment system and a simulated test method. [Background technology]

[0002] Electronic Toll Collection Systems (ETC systems), which use wireless communication, are becoming popular as a toll collection method for toll roads. The lane servers used in ETC systems process tolls based on predetermined toll tables and other information, based on vehicle data transmitted from the vehicle's onboard unit, when a vehicle passes through a toll lane at a toll gate.

[0003] Functionality testing of such lane server software is conducted in a real environment or on-site with actual vehicles running. Tests are conducted assuming various vehicle data (vehicle type, on-board device information, NP number, entrance, traffic history, and vehicle detection data).

[0004] When various cases are checked by driving an actual vehicle, test preparation and implementation takes time and effort, and lane closures occur for extended periods. Furthermore, preparing a real-world environment for each test is a burden for operators. To solve these problems, ETC simulation test systems have been proposed.

DETAILED DESCRIPTION OF THE INVENTION

[0010] An example of a simulated test environment system for conducting a simulated test on a lane server in an ETC system will be described below with reference to the drawings. In this embodiment, the simulated test environment system uses actual driving data acquired from a normally operating lane server 5 to create test data.

[0011] [System Configuration] FIG. 1 is a block diagram showing a schematic configuration of an operating lane server 5 in normal operation according to the first to third embodiments. As shown in Fig. 1, the simulated test environment system 1 is connected to an operating lane server 5 that is operating normally and a test lane server 6 that is the test target. Although Fig. 1 shows a case in which the simulated test environment system 1 is connected to one operating lane server 5, it is also possible to connect multiple operating lane servers 5 and multiple test lane servers 6, and to perform tests on the multiple test lane servers 6 in parallel.

[0012] The simulated test environment system 1 creates test data based on actual driving data acquired from the operational lane server 5 by processing the data, transmits the test data to the test lane server 6, and tests the test lane server 6 by evaluating the operation results of the test lane server 6 returned from the test lane server 6.

[0013] Here, the operating lane server 5 is installed at an operating toll booth, and is therefore connected via a network to the simulated testing environment system 1. On the other hand, the test lane server 6 to be tested may be brought near the simulated testing environment system 1 and connected to the simulated testing environment system 1 for testing, or may be installed in a remote location and connected via a network for testing. The simulated test environment system 1 includes an ETC test control device 2, a test management IF device 3, and an IF conversion device 4.

[0014] As another system definition, a test lane server system SY is defined separately from the simulated test environment system 1. For example, the test lane server system SY may be a test system for each lane server manufacturer. In this case, the test lane server system SY includes a test management IF device 3, an IF conversion device 4, and a test lane server 6.

[0015] The test lane server system SY may be installed at a location different from that of the ETC test control device 2. In this case, the test lane server system SY may be installed at a location away from the operational lane server 5, for example, at each base where it is easy for each manufacturer (each road operator) to conduct testing. Also, since the ETC test control device 2 is a server device common to all manufacturers, one ETC test control device may be connected to the test lane server system SY at each base. The installation locations of the devices are not limited to those described above.

[0016] First, the configuration of the operating lane server 5 for extracting the implementation data will be described. The active lane server 5 is a server in normal operation, and is connected to roadside devices (not shown) installed for each lane of the toll gate, and to a higher-level toll gate server (not shown). The active lane server 5 uses a toll table distributed from a higher-level device (not shown) of the toll system via the toll gate server to perform toll calculations and the like based on the results of communication with vehicles passing through the toll gate lanes, and transmits the results to the toll gate server. Here, the toll table used for toll calculations may be stored in the higher-level device, etc., and the higher-level device may be queried each time a toll calculation is performed.

[0017] 1, the operating lane server 5 includes a communication unit 51, a data processing unit 52, etc. For example, the operating lane server 5 can be configured with one or more computers, and each unit of the operating lane server 5 is configured with hardware such as one or more processors, memories, and communication interfaces. Only the configuration related to the simulated test environment system 1 is shown here, and illustrations and descriptions of other configurations are omitted.

[0018] The communication unit 51 is a communication unit that transmits and receives data necessary for conducting a test to and from the test management IF device 3 of the simulation test environment system 1. For example, the communication unit 51 transmits a log of running data to the test management IF device 3. The data processing unit 52 generates a log of running data.

[0019] Next, the configuration of the test lane server 6 will be described. The test lane server 6 is a lane server to be tested, and after the test is completed, it will actually operate in the same manner as the operational lane server 5. The test lane server 6 has substantially the same hardware configuration as the operational lane server 5, and like the operational lane server 5 in normal operation, it uses a toll table distributed from a host device (not shown) of the toll system via the toll gate server to perform toll calculations and the like based on the results of communication with vehicles passing through the toll gate lanes, and transmits the results to the toll gate server. Here, the toll table used for toll calculations may be stored in the host device, etc., and the host device may be queried each time a toll calculation is performed.

[0020] 1, the test lane server 6 includes a communication unit 61, a data processing unit 62, and an input / output interface (hereinafter referred to as input / output IF) 63. For example, the test lane server 6 can be configured with one or more computers, and each unit of the test lane server 6 is configured with hardware such as one or more processors, memories, and communication interfaces. Only the configuration related to the simulated test environment system 1 is shown here, and illustrations and descriptions of other configurations are omitted.

[0021] The communication unit 61 is a communication unit that transmits and receives data necessary for testing between the test management IF device 3 of the simulated test environment system 1 or the ETC test control device 2 of the simulated test environment system 1. For example, the communication unit 61 transmits vehicle processing data, etc. to the test management IF device 3. The data processing unit 62 generates vehicle processing data, etc. The input / output IF 63 is composed of an input unit such as a keyboard and an output unit such as a monitor, and inputs and outputs various information in response to input operations by an attendant.

[0022] The simulated test environment system 1 includes an ETC test control device 2, a test management IF device 3, and an IF conversion device 4.

[0023] First, the configuration of the test management IF device 3 will be described. The test management IF conversion device 3 is an IF device that is connected to the active lane server 5 that is actually operating at the toll gate, and receives logs from the active lane server 5 in order to create test data. The test management IF conversion device 3 can be configured by one or more computers, and includes hardware such as one or more processors, memories, and communication interfaces.

[0024] The test management IF device 3 includes a communication unit 31 and an acquisition unit 32. The communication unit 31 is a communication unit that receives the traveling data transmitted from the operating lane server 5. The acquisition unit 32 extracts vehicle data including data written to an IC card loaded in an on-board device of a moving vehicle and vehicle detection data of a moving vehicle detected by a vehicle detector (sensor). Here, the acquisition unit 32 further extracts at least one piece of information of work type, processing type, and failure type from the received driving data. The acquisition unit 32 then transmits the data to the ETC test control device 2. The simulation test environment system 1 holds the extracted vehicle data as correct data, and simulates vehicle travel using various simulator functions and the test lane server 6 via the IF conversion device 4 based on the extracted vehicle data.

[0025] Next, the configuration of the ETC test control device 2 will be described. The ETC test control device 2 is a device that creates test data by processing the actual driving data obtained from the operating lane server 5 via the test management IF device 3. The ETC test control device 2 further transmits the test data to the test lane server 6 to operate the test lane server 6, receives vehicle driving processing results transmitted from the test lane server 6, and evaluates the results. For example, the ETC test control device 2 compares the correct answer data with the vehicle driving processing results to confirm whether the test lane server 6 is operating correctly under the assumed conditions.

[0026] The ETC test control device 2 includes a communication unit 21, a data processing unit 22, a confirmation unit 23, and an input / output interface (hereinafter, input / output IF) 24. For example, the ETC test control device 2 can be configured with one or more computers, and each unit of the ETC test control device 2 is configured with hardware such as one or more processors, memories, and communication interfaces. The ETC test control device 2 may also include a user interface that receives various inputs from an attendant and displays various information to the attendant.

[0027] The communication unit 21 communicates with the test management IF device 3, the IF conversion device 4, and the test lane server 6 to send and receive information.

[0028] The data processing unit 22 generates setting data, work patterns, and vehicle data as test data, and transmits them to the IF conversion device 4.

[0029] The setting data is data relating to the toll gates that the vehicle has passed through, and includes toll gate identification information for identifying the toll gates.

[0030] The work style includes information indicating either dedicated operation, mixed operation, or general operation. Dedicated operation is operation specialized in handling ETC processing, which collects tolls via wireless communication with the vehicle's onboard unit. Mixed operation is operation that handles both payments using handed ETC cards and payments using methods other than ETC cards. General operation is operation specialized in handling payments using methods other than ETC cards. Payment using a handed ETC card is payment made by reading the handed ETC card with a card reader and based on the ETC card information read. Payment using methods other than ETC cards is payment by cash. Note that payments using methods other than ETC cards may also include payment by credit card.

[0031] The vehicle data includes data corresponding to signals transmitted from on-board devices of vehicles traveling along the traffic lanes of the toll gate, and vehicle detection data, which corresponds to signals output from multiple vehicle detectors installed along the traffic lanes of the toll gate.

[0032] The confirmation unit 23 confirms various data transmitted from the IF conversion device 4 or the test lane server 6, and evaluates the vehicle travel processing results based on the various data.

[0033] The input / output IF 24 is composed of an input unit such as a keyboard and an output unit such as a monitor, and inputs and outputs various information in response to input operations by the staff. For example, the input / output IF 24 inputs the work type, processing type, device name, and failure type in response to input operations.

[0034] Next, the configuration of the IF conversion device 4 will be described. The IF conversion device 4 is connected to the test lane server 6 and is an IF device for transmitting various test data to the test lane server 6. The IF conversion device 4 receives vehicle processing data transmitted from the test lane server 6 and transmits the vehicle processing data to the ETC test control device. The IF conversion device 4 includes an existing lane equipment simulator (hereinafter referred to as "existing lane equipment SIM") 41, a roadside radio device simulator (hereinafter referred to as "roadside radio device SIM") 42, and a contact point simulator (hereinafter referred to as "contact point SIM") 43. The IF conversion device 4 can be configured with one or more computers, and each simulator of the IF conversion device 4 is configured with hardware such as one or more processors, memories, and communication interfaces. The operation of each simulator will be explained in detail later. The IF conversion device 4 may include simulators other than those described above.

[0035] [Explanation of operation in mock test] In the simulated test environment system 1, the test management IF device 3 receives driving data from the operating lane server 5, acquires at least one piece of information from the driving data, including the work pattern, processing type, and fault type, and transmits the acquired information to the ETC test control device 2. The ETC test control device 2 transmits test data based on the transmitted information. The IF conversion device 4 transmits the test data to the test lane server 6, receives a response from the test lane server 6 according to the test data, and transmits the response to the ETC test control device. The ETC test control device receives the response transmitted from the IF conversion device 4, verifies whether the response corresponds to the test data, and determines that the test lane server 6 is operating correctly if the response corresponds to the test data, or that the test lane server 6 is not operating correctly if the response does not correspond to the test data. The flow of data, signals, notifications, and instructions in a simulation test performed by the simulation test environment system 1 according to the first to third embodiments will be explained below for each of the three embodiments.

[0036] First Embodiment First, the first embodiment will be described. The first embodiment is an embodiment in which a mock test is performed according to the work mode (mixed operation, general operation, or dedicated operation). The test management IF device 3 receives driving data from the operating lane server 5, processes the driving data to obtain information on the work mode, and transmits the obtained information to the ETC test control device 2. The ETC test control device 2 transmits test data based on the transmitted information to the IF conversion device 4, and performs a mock test according to the work mode.

[0037] FIG. 2A is a diagram showing the configuration of the simulated test environment system according to the first embodiment, and also showing the flow of data in a simulated test of mixed operation or general operation.

[0038] When checking whether the test lane server 6 operates correctly in a mixed operation shift mode, the staff member inputs "mixed operation" as the shift mode via the input / output IF 24. When checking whether the test lane server 6 operates correctly in a general operation shift mode, the staff member inputs "general operation" as the shift mode via the input / output IF 24. When checking whether the test lane server 6 operates correctly in a dedicated operation shift mode, the staff member inputs "dedicated operation" as the shift mode via the input / output IF 24.

[0039] The ETC test control device 2 transmits to the IF conversion device 4 an instruction to start (or end) duty in mixed operation (mixed operation instruction) or an instruction to start (or end) duty in general operation (general operation instruction). The IF conversion device 4 transmits an instruction to start (or end) duty in mixed operation or general operation to the test lane server 6. In response, the test lane server 6 transmits vehicle processing data for each vehicle process. Details will be explained in Figures 2B and 2C.

[0040] 2B and 2C are sequence diagrams showing the flow of data in a simulation test of mixed operation or general operation by the simulation test environment system according to the first embodiment. In ST101 of FIG. 2B, the data processing unit 22 of the ETC test control device 2 selects the mixed operation or general operation work style in response to an input of the mixed operation or general operation work style.

[0041] In ST102, the communication unit 21 of the ETC test control device 2 sends to the IF conversion device 4 an instruction to start (or end) work in mixed operation (mixed operation instruction), or an instruction to start (or end) work in general operation (general operation instruction).

[0042] The existing lane equipment SIM 41 of the IF conversion device 4 receives an instruction to start (or end) duty in mixed operation or general operation.

[0043] In ST103, the existing lane equipment SIM41 of the IF conversion device 4 transmits to the test lane server 6 an instruction to start (or end) duty in mixed operation or general operation.

[0044] The communication unit 61 of the test lane server 6 receives an instruction to start work in mixed operation or normal operation. The data processing unit 62 generates a request to start (or end) work in the specified work mode based on the instruction to start work in mixed operation or normal operation.

[0045] In ST104, the communication unit 61 of the test lane server 6 requests the ETC test control device 2 to start (or end) work in the specified work mode. Alternatively, the communication unit 61 of the test lane server 6 may request the ETC test control device 2 to start (or end) work in the specified work mode via the IF conversion device 4.

[0046] The communication unit 21 of the ETC test control device 2 receives the request from the test lane server 6. Alternatively, the communication unit 21 may receive the request from the test lane server 6 via the IF conversion device 4. The data processing unit 22 of the ETC test control device 2 generates an instruction to start (or end) work in the specified work mode.

[0047] In ST105, the communication unit 21 of the ETC test control device 2 transmits to the test lane server 6 an instruction to start (or end) work in the specified work mode.

[0048] The communication unit 61 of the test lane server 6 receives instructions from the ETC test control device 2.

[0049] In ST106, work begins (or ends) in the designated work format.

[0050] 2C, the data processing unit 62 of the test lane server 6 generates a vehicle processing result corresponding to the vehicle travel and ETC processing. The vehicle processing result generated here is a mixed operation processing result corresponding to the mixed operation instruction, or a general operation processing result corresponding to the general operation instruction.

[0051] For example, the mixed operation processing result or the general operation processing result includes input information received by an attendant terminal connected to the test lane server 6. The attendant terminal has an input interface and an ETC card reader that reads an ETC card. The input information includes reader read information read by the ETC card reader, or cash payment information received by the input interface. For example, the mixed operation processing result includes information indicating ETC card payment or cash payment using a card reader. The general operation processing result includes information indicating cash payment.

[0052] In ST108, the communication unit 61 of the test lane server 6 transmits the vehicle processing result to the IF conversion device 4. The existing lane equipment SIM 41 of the IF conversion device 4 receives the vehicle processing result from the test lane server 6.

[0053] In ST109, the existing lane equipment SIM 41 of the IF conversion device 4 transmits the vehicle processing result to the ETC test control device 2. The communication unit 21 of the ETC test control device 2 receives the vehicle processing result from the IF conversion device 4.

[0054] In ST110, the confirmation unit 23 of the ETC test control device 2 confirms whether the received vehicle processing result is a vehicle processing result corresponding to the shift type selected in ST101. When the confirmation unit 23 receives a mixed operation processing result, it confirms whether the mixed operation processing result is a result corresponding to mixed operation.

[0055] For example, when the mixed operation processing result indicates ETC card payment using a card reader or cash payment, the confirmation unit 23 confirms that the result is correct for mixed operation. Also, when the confirmation unit 23 receives a general operation processing result, it confirms whether the general operation processing result is a result that corresponds to general operation. For example, when the general operation processing result indicates cash payment, the confirmation unit 23 confirms that the result is correct for general operation.

[0056] FIG. 3A is a diagram showing the configuration of the simulation test environment system according to the first embodiment, and also showing the flow of data in a simulation test of dedicated operation by the system. When checking whether the test lane server 6 operates correctly in the dedicated operation shift mode, the staff member inputs dedicated operation as the shift mode via the input / output IF 24.

[0057] The ETC test control device 2 transmits an instruction (dedicated operation instruction) to the IF conversion device 4 to start (or end) duty in dedicated operation, but the IF conversion device 4 does not perform duty start (or duty end) processing even when it receives the instruction to start (or end) duty in dedicated operation. Details will be explained in FIG. 3B.

[0058] FIG. 3B is a sequence diagram showing the flow of data in a simulation test of dedicated operation by the simulation test environment system according to the first embodiment. In ST101 of FIG. 3B, the data processing unit 22 of the ETC test control device 2 selects the dedicated operation duty mode in response to the input of the dedicated operation duty mode.

[0059] In ST202, the communication unit 21 of the ETC test control device 2 transmits to the IF conversion device 4 an instruction (dedicated operation instruction) to start (or end) work in dedicated operation.

[0060] In ST203, even if the existing lane device SIM41 of the IF conversion device 4 receives a duty start (or duty end) instruction for the dedicated operation, the existing lane device SIM41 does not perform duty start (or duty end) processing. Therefore, the test lane server 6 does not perform any special operation.

[0061] In ST204, the communication unit 21 of the ETC test control device 2 transmits to the test lane server 6 an instruction to start (or end) work in the dedicated operation.

[0062] In ST205, work begins (or ends) in a dedicated operation mode.

[0063] After this, the data processing unit 62 of the test lane server 6 generates a vehicle processing result corresponding to the vehicle travel and ETC processing. The vehicle processing result generated here is a dedicated operation processing result corresponding to the dedicated operation instruction. For example, the dedicated operation processing result includes the results of communication with the vehicle's onboard device, etc.

[0064] The communication unit 61 of the test lane server 6 transmits the vehicle processing result to the IF conversion device 4. The existing lane equipment SIM 41 of the IF conversion device 4 receives the vehicle processing result from the test lane server 6.

[0065] The existing lane equipment SIM 41 of the IF conversion device 4 transmits the vehicle processing result to the ETC test control device 2. The communication unit 21 of the ETC test control device 2 receives the vehicle processing result from the IF conversion device 4.

[0066] The confirmation unit 23 of the ETC test control device 2 confirms whether the received vehicle processing result is a vehicle processing result corresponding to the duty mode selected in ST201. When the confirmation unit 23 receives a dedicated operation processing result, it confirms whether the dedicated operation processing result is a result corresponding to dedicated operation. For example, when the dedicated operation processing result indicates the result of communication with the vehicle's onboard unit, the confirmation unit 23 confirms that the result is a correct result corresponding to dedicated operation.

[0067] As explained above, the ETC test control device 2 instructs the IF conversion device 4 on the duty mode when starting a test. As a result, the existing lane equipment SIM 41 of the IF conversion device 4 performs duty start processing specifying the duty mode (operation mode) for the test lane server 6, and the ETC test control device 2 can execute a mock test according to the duty mode. The ETC test control device 2 compares the instructed duty mode with the received test results to confirm whether the test lane server 6 is operating correctly according to the duty mode.

[0068] <Second embodiment> Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that it uses processing types (normal ETC, non-ETC, IC card not inserted, communication abnormality, etc.). In the second embodiment, a simulation test of a normal vehicle and a simulation test of an abnormal vehicle according to the failure type are performed. The test management IF device 3 receives driving data from the operating lane server 5, processes the driving data to obtain information on the processing type, and transmits the obtained information to the ETC test control device 2. The ETC test control device 2 transmits test data based on the transmitted information to the IF conversion device 4 and performs a simulation test according to the processing type.

[0069] [Mock test for normal vehicle] FIG. 4 is a diagram showing the configuration of a simulation test environment system according to the second embodiment, and also showing the flow of data in a simulation test of a normal vehicle. 4, the ETC test control device 2 transmits vehicle data (attribute data) to the IF conversion device 4. The roadside wireless device SIM 42 of the IF conversion device 4 generates vehicle data of a normal ETC for simulating wireless communication processing between a road and a vehicle, and transmits the vehicle data of a normal ETC to the test lane server 6. For example, the vehicle data of a normal ETC includes ETC card information.

[0070] The ETC test control device 2 may transmit vehicle data including attribute data and a processing type to the IF conversion device 4. In this case, the processing type indicates normal.

[0071] The test lane server 6 receives the vehicle data of the normal ETC and transmits a normal processing result corresponding to the vehicle data of the normal ETC. The confirmation unit 23 of the ETC test control device 2 receives the normal processing result corresponding to the vehicle data of the normal ETC transmitted from the test lane server 6 and confirms that the normal processing result is a correct result corresponding to the vehicle data of the normal ETC.

[0072] [Mock test of abnormal vehicle] Next, we will explain how the simulated testing environment system simulates abnormalities in road-to-vehicle processing. For example, the simulated testing environment system simulates the following three cases: (1) Non-ETC (2) Communication error (specify action sequence) (3) IC card not inserted FIG. 5A is a diagram showing the configuration of a simulation test environment system according to the second embodiment, and also showing the flow of data in a simulation test of an abnormal vehicle. 5A, the data processing unit 22 of the ETC test control device 2 generates vehicle data including attribute data and a processing type, and the communication unit 21 transmits the vehicle data to the IF conversion device 4. The processing type indicates an abnormality, and further indicates non-ETC, a communication abnormality, or no IC card inserted.

[0073] When the roadside radio device SIM42 of the IF conversion device 4 receives vehicle data including attribute data and processing type, it generates abnormal vehicle data according to the processing type indicating an abnormality and transmits the abnormal vehicle data to the test lane server 6.

[0074] For example, the roadside radio device SIM42 generates abnormal vehicle data indicating a non-ETC vehicle according to the non-ETC processing type, and transmits the data to the test lane server 6. The roadside radio device SIM42 also generates abnormal vehicle data indicating a communication abnormality according to the processing type of the communication abnormality, and transmits the data to the test lane server 6. The roadside radio device SIM42 also generates abnormal vehicle data indicating an IC card not being inserted according to the processing type of an IC card not being inserted, and transmits the data to the test lane server 6.

[0075] FIG. 5B is a sequence diagram showing an example of signal processing between the roadside device SIM and the test lane server in a simulation test of an abnormal vehicle performed by the simulation test environment system according to the second embodiment. As shown in ST301, the roadside radio device SIM 42 of the IF conversion device 4 transmits a response according to the processing type.

[0076] Alternatively, as shown in ST302, the roadside radio device SIM42 of the IF conversion device 4 does not transmit a response according to the processing type.

[0077] If the processing type indicates "normal", the roadside radio unit SIM 42 of the IF conversion device 4 performs normal road-to-vehicle communication processing.

[0078] If the processing type indicates "non-ETC", the roadside wireless device SIM 42 of the IF conversion device 4 does not respond to the test lane server 6, thereby simulating the result of a "non-ETC" vehicle travel.

[0079] If the processing type indicates "communication abnormality," the roadside wireless device SIM42 of the IF conversion device 4 simulates the vehicle driving result of "communication abnormality" by generating a communication abnormality (no response or abnormal signal) between the road and the vehicle during the specified Action sequence.

[0080] If the processing type is "IC card not inserted," the roadside wireless device SIM42 of the IF conversion device 4 sets the result "IC card not inserted" in the Notify Application RSU command in road-to-vehicle communication and sends the command to the test lane server 6, thereby simulating the vehicle driving result of "IC card not inserted."

[0081] If the IF conversion device 4 does not respond, the test lane server 6 transmits an abnormality processing result corresponding to the no-response. If the IF conversion device 4 causes a communication abnormality, the test lane server 6 transmits an abnormality processing result corresponding to the communication abnormality. If the IF conversion device 4 transmits "IC card not inserted," the test lane server 6 transmits an abnormality processing result corresponding to "IC card not inserted."

[0082] The confirmation unit 23 of the ETC test control device 2 checks whether the abnormality processing result sent from the test lane server 6 is a result corresponding to the processing type. If the processing type is a type indicating non-ETC, the confirmation unit 23 checks whether the abnormality processing result is a result corresponding to non-ETC. Furthermore, if the processing type is a type indicating a communication abnormality, the confirmation unit 23 checks whether the abnormality processing result is a result corresponding to a communication abnormality. Furthermore, if the processing type is a type indicating no IC card inserted, the confirmation unit 23 checks whether the abnormality processing result is a result corresponding to no IC card inserted.

[0083] As described above, the ETC test control device 2 adds the processing type to the vehicle data (attribute data) and transmits it to the IF conversion device 4, which allows the roadside radio unit SIM42 of the IF conversion device 4 to simulate a processing sequence according to the processing type specified for each vehicle between the test lane server 6. The ETC test control device 2 compares the specified processing type with the received test results to confirm whether the test lane server 6 is operating correctly according to the processing type.

[0084] <Third embodiment> Next, a third embodiment will be described. The third embodiment differs from the first and second embodiments in that it uses a fault type (line abnormality or contact system fault) acquired from the driving data of the operating lane server 5. The third embodiment performs a simulation test according to the fault type. The test management IF device 3 receives the driving data from the operating lane server 5, processes the driving data to acquire information on the fault type, and transmits the acquired information to the ETC test control device 2. The ETC test control device 2 transmits test data based on the transmitted information to the IF conversion device 4 and performs a simulation test according to the fault type.

[0085] FIG. 6A is a diagram showing the configuration of a simulation test environment system according to the third embodiment, and also showing the flow of data in a simulation test according to a fault type. 6A, the data processing unit 22 of the ETC test control device 2 generates vehicle data including vehicle detection data, the name of the faulty device, and the fault type, and the communication unit 21 transmits the vehicle data to the IF conversion device 4. The IF conversion device 4 receives the vehicle data.

[0086] The existing lane device SIM41, roadside radio device SIM42, and contact SIM43 of the IF conversion device 4 generate a failure notification according to the failure type included in the vehicle data, and transmit the failure notification to the test lane server 6.

[0087] FIG. 6B is a sequence diagram showing an example of signal processing between the IF conversion device and the test lane server in a simulation test according to a fault type performed by the simulation test environment system according to the third embodiment. When the ETC test control device 2 transmits a fault (abnormality notification, line disconnection) in the socket communication system equipment as the fault type included in the vehicle data, the existing lane equipment SIM41 or the roadside wireless device SIM42 of the IF conversion device 4 transmits a fault notification according to the fault type.

[0088] For example, the existing lane equipment SIM 41 or the roadside wireless device SIM 42 of the IF conversion device 4 receives the fault type and notifies the test lane server 6 of the abnormality via socket communication or disconnects the line. The test lane server 6 simulates operation in a state where a fault has occurred in a peripheral device and transmits the resulting fault processing result to the ETC test control device 2.

[0089] Furthermore, when the ETC test control device 2 transmits a fault type indicating a fault in a contact system device, the contact SIM 43 of the IF conversion device 4 receives the fault type and notifies the test lane server 6 of the fault contact signal. The test lane server 6 simulates operation in a state in which a fault in a contact system device has occurred, and transmits the resulting fault processing result to the ETC test control device 2.

[0090] The communication unit 21 of the ETC test control device 2 receives the failure processing result from the test lane server 6. The confirmation unit 23 confirms whether the failure processing result corresponds to the failure type.

[0091] If the fault type indicates a line abnormality, the confirmation unit 23 confirms whether the fault processing result corresponds to the line abnormality. Also, if the fault type indicates a contact-system equipment failure, the confirmation unit 23 confirms whether the fault processing result corresponds to the contact-system equipment failure.

[0092] As explained above, the ETC test control device 2 adds the name of the faulty device and the fault type to the vehicle data (vehicle detection data) and sends it to the IF conversion device 4, and the IF conversion device 4 notifies the test lane server 6 of the fault according to the fault type, thereby simulating vehicle travel under conditions in which a fault has occurred. The ETC test control device 2 collates the instructed fault type with the received test results to confirm whether the test lane server 6 is operating correctly according to the processing type.

[0093] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
