[0046] An embodiment of the exhaust gas analysis system of the present invention will be described below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, the exhaust gas analysis system 100 of this embodiment includes: a test chamber S1, a chassis dynamometer 10, and an exhaust gas analysis device 20, etc., so that a test vehicle V is simulated to run on the chassis dynamometer 10, and the performance related to the fuel consumption, power consumption (power consumption rate of electric vehicles, etc.), and exhaust gas composition, etc. of the test vehicle V can be tested. In addition, the test chamber S1 is a room for carrying the test vehicle V inside and performing a running test, and is configured to be isolated from the outside and set to various environments (temperature, etc.) required for measurement.

[0048] And, if Figure 1 As shown, the exhaust gas analysis system 100 further includes a storage room S2 for storing the test vehicle V and a vehicle management device 30 for managing temperature information of the test vehicle V.

[0049] The storage room S2 is a room for storing one or more test vehicles V at least before testing. When storing a plurality of test vehicles V in the storage room S2, the test vehicles V may be stored in multiple floors or all the test vehicles V may be stored in one floor.

[0050] The exhaust gas analysis system 100 of this embodiment includes a plurality of storage rooms S2 (here, two rooms, a first storage room and a second storage room). Each storage room S2 is provided with an air conditioning mechanism (not shown) for adjusting the indoor temperature to a predetermined temperature and a first temperature sensor T1 for detecting the indoor temperature. In addition, a second temperature sensor T2 is mounted on all or part of the test vehicles V stored in the plurality of storage rooms S2.

[0051] The vehicle management device 30 is a general-purpose or special-purpose computer including a CPU, a memory, a display, an input device (keyboard or mouse, etc.), and a communication interface. The CPU and its peripheral devices cooperate according to the vehicle management program recorded in the memory, such as Figure 2 The vehicle management device 30 functions as an ambient temperature acquisition unit 31, a vehicle temperature acquisition unit 32, a position information acquisition unit 33, and a recording unit 34. The vehicle management device 30 may be a portable mobile terminal such as a smartphone or a tablet terminal.

[0052] Hereinafter, the operation of the vehicle management device 30 will be described and each part will be described.

[0053] The ambient temperature acquisition unit 31 acquires the temperature detected by the first temperature sensor T1 together with the room identifier indicating the storage room S2 in which the first temperature sensor T1 is installed, and acquires the temperature as the ambient temperature of the test vehicle V stored in the storage room S2 (hereinafter referred to as the ambient temperature). In addition, the communication between the ambient temperature acquisition unit 31 and the first temperature sensor T1 can utilize various communication networks such as wireless communication or public lines.

[0054] In this embodiment, if Figure 1 As shown, the first temperature sensor T1 is also provided in the test room S1 for testing the test vehicle V. Furthermore, the ambient temperature acquisition unit 31 acquires the temperature detected by the first temperature sensor T1 provided in the test room S1 together with the room identifier indicating the test room S1, and acquires the temperature as the ambient temperature of the test vehicle V tested in the test room S1.

[0055] The vehicle temperature acquisition unit 32 acquires the temperature detected by the second temperature sensor T2 together with the vehicle identifier indicating the test vehicle V equipped with the second temperature sensor T2, and acquires the temperature as the temperature of the test vehicle V (hereinafter referred to as the vehicle temperature). In addition, the communication between the vehicle temperature acquisition unit 32 and the second temperature sensor T2 can utilize various communication networks such as wireless communication or public lines.

[0056] The position information acquisition unit 33 acquires the position information of the test vehicle V together with the vehicle identifier indicating the vehicle V. The position information includes at least information for specifying the indoor position of the test vehicle V. Here, the room identifier indicating the storage room S2 or the test room S1 is used as the position information. In addition to or instead of the room identifier, the position information of the test vehicle V acquired from the GPS may be used.

[0057] In this embodiment, if Figure 1 As shown, each test vehicle V is equipped with a beacon transmitter B1 for transmitting a beacon signal, and a beacon receiver B2 for receiving the beacon signal is installed in the storage room S2 or the test room S1. The beacon signal contains identification information for identifying the beacon transmitter B1, and the identification information is associated with the vehicle identifier on which the beacon transmitter B1 is installed.

[0058] Furthermore, when the beacon receiver B2 receives the beacon signal, the position information acquisition unit 33 acquires the vehicle identifier associated with the identification information included in the received beacon signal from the beacon receiver B2, and acquires the room identifier indicating the storage room S2 or the test room S1 where the beacon receiver B2 is installed as the position information. In addition, the communication between the position information acquisition unit 33 and the beacon receiver B2 can utilize various wireless communications using, for example, a wireless LAN.

[0059] The recording unit 34 records the ambient temperature of the test vehicle V in a predetermined area of ​​the memory in association with the location information of the test vehicle V. In addition, the recording unit 34 is not limited to recording in the memory provided in the vehicle management device 30, and may be recorded in an external memory such as a cloud, a USB memory, or an SD card.

[0060] Specifically, the recording unit 34 compares the vehicle identifier obtained by the ambient temperature acquisition unit 31 together with the ambient temperature of the test vehicle V and the vehicle identifier obtained by the position information acquisition unit 33 together with the position information of the test vehicle V, and when these vehicle identifiers match, the ambient temperature and the position information are recorded in association. In addition to the ambient temperature of the test vehicle V and the position information of the test vehicle V, the recording unit 34 may also record the vehicle identifier of the test vehicle V in the memory in association.

[0061] More specifically, the recording unit 34 records, for example, the time series data of the ambient temperature and the time series data of the position information in association with each other. In this case, the time series data of the ambient temperature and the time series data of the position information are associated with each other at a time, thereby recording the ambient temperature and the position information acquired by the position information acquisition unit 33 at the time when the ambient temperature acquisition unit 31 acquires the ambient temperature in association with each other. In addition to the ambient temperature of the test vehicle V and the position information of the test vehicle V, the recording unit 34 may also record in the memory the time information when these information are acquired in association with each other.

[0062] The recording unit 34 of the present embodiment stores the vehicle identifier indicating the test vehicle V and the vehicle temperature acquired by the vehicle temperature acquisition unit 32 in association with the ambient temperature of the test vehicle V and the position information of the test vehicle V. In addition, when the first temperature sensor T1 of the test room S1 or the storage room S2 does not function due to a malfunction or the like, the storage unit 32 may record the vehicle temperature of the test vehicle V, the position information of the test vehicle V, and the vehicle identifier of the test vehicle V in association with each other.

[0063] Specifically, the following method can be cited: the recording unit 34 associates the time series data of the ambient temperature, the time series data of the position information, and the time series data of the vehicle temperature. Specifically, as in the above method, each time series data is associated at the time. In this case, the ambient temperature, the position information obtained by the position information obtaining unit 33 at the time when the ambient temperature obtaining unit 31 obtains the ambient temperature, and the vehicle temperature obtained by the vehicle temperature obtaining unit 32 at the same time are recorded in association. That is, the recording unit 34 records these mutually related information in a database form.

[0064] The vehicle management device 30 herein includes an output unit 35, which outputs at least the associated ambient temperature and position information in a comparable manner. Specifically, the output unit 35 outputs the associated ambient temperature and position information in a comparable manner, for example, to a display of the vehicle management device 30 or a display of a portable mobile terminal, such as a smartphone or a tablet terminal, which is separate from the vehicle management device 30, and also outputs the ambient temperature and the vehicle temperature associated with the position information in a comparable manner.

[0065] In addition, the output unit 35 can output the database recorded by the recording unit 34 as a list, or can use the vehicle identifier, location information, time information, etc. as keywords to extract the ambient temperature or vehicle temperature of the test vehicle V associated with them from the database. In addition, the output unit 35 can output the database recorded by the recording unit 34 to other servers, etc. by using a wired or wireless communication device or an external memory.

[0066] According to the vehicle management device 30 configured as described above, since the ambient temperature of the test vehicle V and the position information of the test vehicle V are recorded in a correlated manner, the exhaust gas analysis system 100 capable of obtaining temperature traceability of the test vehicle V can be constructed.

[0067] In addition, the vehicle management device 30 not only obtains the ambient temperature of the test vehicle V but also obtains the vehicle temperature of the test vehicle V, so it is possible to grasp their temperature difference, etc., and not only obtain the temperature traceability of the test vehicle V but also check whether the temperature of the test vehicle V in the storage room S2 is adjusted to the specified temperature, etc.

[0068] In addition, the present invention is not limited to the above-described embodiments.

[0069] For example, in the above-described embodiment, the ambient temperature, position information, and vehicle temperature of the test vehicle V are recorded in association with each other, but the vehicle temperature is not necessarily associated with each other. In this case, it is not necessary to provide the second temperature sensor T2 in the test vehicle V, and the vehicle management device 30 does not need to have the function of the vehicle temperature acquisition unit 32.

[0070] A plurality of first temperature sensors T1 and a plurality of beacon receivers B2 may be installed in the storage room S2.

[0071] In the present embodiment, the position information acquisition unit 33 may be configured to identify the beacon receiver B2 that has received the beacon signal transmitted from the beacon transmitter B1 mounted on the test vehicle V from among the plurality of beacon receivers B2 installed in the storage room S2 .

[0072] Thus, the position information acquisition unit 33 can acquire the installation location of the identified beacon receiver B2 in the storage room S2 as position information indicating the detailed position of the test vehicle V in the storage room S2.

[0073] In the above configuration, the ambient temperature acquisition unit 31 may be configured to acquire the temperature detected by the first temperature sensor T1 closest to the test vehicle V as the ambient temperature of the test vehicle V based on the detailed position of the test vehicle V acquired by the position information acquisition unit 33 .

[0074] According to such a configuration, even when the storage room S2 is assumed to be large and temperature variations exist depending on the location, the accurate ambient temperature of the test vehicle V can be acquired.

[0075] In addition, in the above embodiment, the beacon transmitter B1 is mounted on the test vehicle V and the beacon receiver B2 is set in the storage room S2 or the test room S1, but the beacon transmitter B1 can also be set in the storage room S2 or the test room S1 and the beacon receiver B2 is mounted on the test vehicle V.

[0076] In addition, if Figure 3 As shown, a third temperature sensor T3 may be provided in a parking lot where the test vehicle V is parked, for example, outside a house.

[0077] In this case, the position information acquisition unit 33 may acquire the position information of the test vehicle V from the GPS.

[0078] In the above configuration, the recording unit 34 can obtain the ambient temperature of the test vehicle V parked in the parking lot from the third temperature sensor T3 and record the ambient temperature and the position information obtained from the GPS of the test vehicle V in association with each other.

[0079] According to this configuration, not only the ambient temperature of the test vehicle V indoors but also the ambient temperature of the test vehicle V outdoors can be acquired in a manner that allows the temperature of the test vehicle V to be traced back.

[0080] Furthermore, the vehicle temperature acquisition unit 32 may acquire the vehicle temperature from a test vehicle V parked in a parking lot.

[0081] In this case, the position information acquisition unit 33 may acquire the position information of the test vehicle V from the GPS.

[0082] In the above configuration, the recording unit 34 may record the vehicle temperature of the test vehicle V parked in the parking lot and the position information acquired from the GPS of the test vehicle in association with each other.

[0083] In addition, in this case, there is no need to set up Figure 3 A third temperature sensor T3 is shown.

[0084] In addition, if Figure 4 As shown, the vehicle management device 30 can be configured to include a remaining capacity acquisition unit 36 ​​for acquiring the remaining capacity of a battery mounted on a test vehicle V, and the recording unit 34 records the remaining capacity acquired by the remaining capacity acquisition unit 36 ​​in association with the ambient temperature of the test vehicle V and the location information of the test vehicle V.

[0085] In addition, although not shown in the figure, the vehicle management device 30 can be configured to include an analysis result acquisition unit that obtains the analysis results of the exhaust gas analysis device 20, and the recording unit 34 records the analysis results obtained by the analysis result acquisition unit in association with the ambient temperature of the test vehicle V and the position information of the test vehicle V.

[0086] According to this structure, not only the ambient temperature of the test vehicle V but also a wide range of traceability including the remaining capacity of the battery and the exhaust gas measurement results can be obtained.

[0087] On this basis, the output unit 35 of the embodiment can output the ambient temperature of the test vehicle V detected by the first temperature sensor T1 and the vehicle temperature of the test vehicle V detected by the second temperature sensor T2 in a comparable manner.

[0088] Furthermore, the vehicle management device 30 may also function as a notification unit that compares the ambient temperature of the test vehicle V and the vehicle temperature of the test vehicle V and notifies the situation when the temperature difference between them exceeds a predetermined threshold value.

[0089] According to such a configuration, for example, a problem in the temperature control management of the storage room S2 can be grasped.

[0090] In addition, if Figure 5 As shown, the vehicle management device 30 of the present invention can be configured to record the tire pressure of the test vehicle V.

[0091] Specifically, the following can be cited: Figure 5 As shown, the vehicle identifier of the test vehicle V is obtained by, for example, reading a bar code or QR code assigned to the test vehicle V by a portable or fixed computer C, and the vehicle identifier is correlated with the result of measuring the tire pressure of the test vehicle V and recorded in the memory of the vehicle management device 30.

[0092] For example, when recording tire pressure, the tire pressures of the front, rear, left, and right tires of the test vehicle V are measured using the pressure sensor S1, and the pressure data indicating the measurement results are sent to the computer C via wireless communication.

[0093] At this time, the display of computer C can be made to display, for example, Figure 6 The measurement screen shown. Specifically, measurement start buttons (FL, FR, RL, RR) for measuring the air pressure of the front, rear, left and right tires are displayed in front of, behind, and on the left and right sides of the vehicle icon representing the test vehicle. Furthermore, if the input start button corresponding to the tire to be measured is pressed and the air pressure of the tire is measured by the air pressure sensor S1, the measured value is sent to the computer C, and the measured value is displayed in a curve graph on the display of the computer C. The computer C determines the measured value as air pressure data and displays it in a measurement result display area set, for example, near the measurement start button. The air pressure data of each tire measured in the above manner is associated with the vehicle identifier and output to the vehicle management device 30 for management. Specifically, the air pressure data and the vehicle identifier of the test vehicle V are output to the vehicle management device 30, and the recording unit 34 records them in a prescribed area of ​​the memory in association with each other. In addition, the date and time of the air pressure measurement and the position information of the test vehicle V when the air pressure is measured can be associated with the air pressure data and the vehicle identifier and managed.

[0094] In addition, as a method of managing the above-mentioned air pressure data by the vehicle management device 30, the following method can be cited: by using a reading device provided in the vehicle management device 30 to read, for example, a bar code or a QR code displayed on the display of the portable computer C, and output various data to the vehicle management device 30. However, it is also possible to output various data to the vehicle management device 30 by, for example, a wired or wireless method.

[0095] In addition, the vehicle management device 30 of the present invention can manage the fuel information related to the fuel filled in the test vehicle V in association with the vehicle identifier of the test vehicle V. Specifically, the fuel information indicating the type of fuel and / or the filling amount and the vehicle identifier of the test vehicle V are output to the vehicle management device 30, and the recording unit 34 records them in a predetermined area of ​​the memory in association with each other. In addition, the filling date and time of the fuel and the location information of the test vehicle V can be associated with the fuel information and the vehicle identifier and managed. In addition, the fuel information can be obtained by reading, for example, a barcode or a QR code provided on a fuel filling device or a fuel container.

[0096] Furthermore, when the test vehicle V is an electric vehicle or a hybrid vehicle, the vehicle management device 30 can associate the charging data indicating the remaining battery capacity (SOC: State Of Charge) of the test vehicle V with the vehicle identifier of the test vehicle V and manage them. Specifically, the charging data and the vehicle identifier are output to the vehicle management device 30, and the recording unit 34 associates them with each other and records them in a predetermined area of ​​the memory. In addition, the charging date and time and the location information of the test vehicle V can be associated with the charging data and the vehicle identifier and managed.

[0097] Furthermore, the vehicle management device 30 can associate the vehicle weight data indicating the weight of the test vehicle V with the vehicle identifier of the test vehicle V and manage them. Specifically, the vehicle weight data and the vehicle identifier are output to the vehicle management device 30, and the recording unit 34 records them in a predetermined area of ​​the memory in association with each other. In addition, the date and time of measurement of the vehicle weight and the position information of the test vehicle V at which the vehicle weight is measured can be associated with the vehicle weight data and the vehicle identifier and managed.

[0098] In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
