[Technical Field]

[0001] The present invention relates to a management device for managing temperature information of a test vehicle. [Background technology]

[0002] Conventionally, test vehicles to be tested for performance tests, etc., are stored in advance in a room called a soak chamber, which is temperature-controlled to a predetermined temperature, as shown in Patent Document 1, and are then transported from there to a dynamometer or the like during testing.

[0003] The temperature of this soak chamber is a factor that can affect test results, such as exhaust gas measurements, etc. Similar to the temperature of the soak chamber, the temperature of the test room in which the test vehicle is tested and various measurements of the test vehicle in the soak chamber (e.g., temperature measurements of the test vehicle) are also factors that can affect test results.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-53023 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, in order to obtain precise test results, it is now necessary to obtain traceability of the temperature of the soak chamber and various measurement values of the test vehicle in the soak chamber (for example, temperature measurement values related to the test vehicle).The main objective of this invention is to build a system that can collect the temperature of the soak chamber and various measurement values of the test vehicle in the soak chamber and obtain that traceability. [Means for solving the problem]

[0006] That is, the vehicle management device according to the present invention is a vehicle management device that manages the temperature information of a test vehicle, and is provided in a soak chamber where the test vehicle is stored or a test chamber where the test vehicle is tested. It is characterized by comprising a surrounding temperature acquisition unit that acquires the surrounding temperature of the test vehicle from a first temperature sensor, a position information acquisition unit that acquires the position information of the test vehicle, and a recording unit that records the surrounding temperature of the test vehicle and the position information of the test vehicle in association with each other.

[0007] According to the vehicle management device configured as described above, since the surrounding temperature of the test vehicle and the position information of the test vehicle are recorded in association with each other, a system capable of acquiring the temperature traceability of the test vehicle can be constructed.

[0008] The vehicle management device further comprises a vehicle temperature acquisition unit that acquires the vehicle temperature, which is the temperature of the test vehicle, from a second temperature sensor mounted on the test vehicle, and it is preferable that the recording unit further records the vehicle temperature of the test vehicle in association with the surrounding temperature of the test vehicle and the position information of the test vehicle. With such a configuration, since the vehicle management device acquires not only the surrounding temperature of the test vehicle but also the vehicle temperature of the test vehicle, it is possible to grasp the temperature difference and the like, and not only to acquire the temperature traceability of the test vehicle but also to check whether the test vehicle is temperature-controlled to a predetermined temperature in the soak chamber.

[0009] One of a beacon transmitter and a beacon receiver that transmit and receive beacon signals is provided in the soak chamber or the test chamber, and the other is mounted on the test vehicle, and it is preferable that the position information acquisition unit acquires the position information of the test vehicle based on the identification information included in the beacon signal received by the beacon receiver.

[0010] It is preferable that a plurality of first temperature sensors are provided in the soak chamber, and the ambient temperature acquisition unit acquires the ambient temperature of the test vehicle from the first temperature sensor closest to the test vehicle based on the location information of the test vehicle acquired by the location information acquisition unit. With this configuration, even if the soak chamber is large and the temperature varies depending on the location, it is possible to obtain an accurate ambient temperature of the test vehicle.

[0011] It is preferable that the vehicle temperature acquisition unit acquires the vehicle temperature from the test vehicle parked in a parking lot, the location information acquisition unit acquires the location information of the test vehicle from a GPS, and the recording unit associates and records the vehicle temperature of the test vehicle parked in the parking lot with the location information acquired from the GPS of the test vehicle. With this configuration, not only the ambient temperature of the test vehicle indoors but also the vehicle temperature of the test vehicle outdoors can be acquired as the temperature traceability of the test vehicle.

[0012] It is preferable that the recording unit further associates and records the remaining capacity of a battery mounted on the test vehicle in addition to the ambient temperature of the test vehicle and the location information of the test vehicle. With this configuration, it is possible to obtain a wide range of traceability, including not only the ambient temperature of the test vehicle but also the remaining battery capacity.

[0013] The exhaust gas analysis system of the present invention is characterized by comprising the above-mentioned vehicle management device, a chassis dynamometer on which the test vehicle is placed, and an exhaust gas analysis device that analyzes the exhaust gas from the test vehicle.

[0014] The vehicle management program according to the present invention is a program used for vehicle management that manages the temperature information of a test vehicle, and causes a computer to function as a surrounding temperature acquisition unit that acquires the surrounding temperature of the test vehicle from a first temperature sensor provided in a soak chamber where the test vehicle is stored or a test chamber where the test vehicle is tested, a position information acquisition unit that acquires the position information of the test vehicle, and a recording unit that records the surrounding temperature of the test vehicle and the position information of the test vehicle in association with each other.

[0019] An embodiment of an exhaust gas analysis system according to the present invention will be described below with reference to the drawings.

[0020] 1, the exhaust gas analysis system 100 of this embodiment includes a test chamber S1, a chassis dynamometer 10, an exhaust gas analyzer 20, etc., and allows a test vehicle V to be simulated on the chassis dynamometer 10 to test the performance of the test vehicle V in terms of fuel economy, electricity consumption (the power consumption rate of an electric vehicle, etc.), exhaust gas components, etc. The test chamber S1 is a room into which the test vehicle V is brought and used for running tests, and is configured to be isolated from the outside and to be able to set various environments (temperature, etc.) required for measurement.

[0021] As shown in FIG. 1, the exhaust gas analysis system 100 further includes a soak chamber S2 in which the test vehicle V is stored, and a vehicle management device 30 that manages the temperature information of the test vehicle V.

[0022] The soak chamber S2 is a room for storing one or more test vehicles V at least prior to testing. When storing multiple test vehicles V in the soak chamber S2, these test vehicles V may be stored across multiple floors, or all test vehicles V may be stored on a single floor.

[0023] The exhaust gas analysis system 100 of this embodiment is equipped with a plurality of soak chambers S2 (here, two chambers: a first soak chamber and a second soak chamber). Each soak chamber S2 is equipped with an air conditioning mechanism (not shown) for adjusting the temperature of the interior of the chamber to a predetermined temperature, and a first temperature sensor T1 for detecting the temperature inside the chamber. In addition, a second temperature sensor T2 is installed in all or some of the test vehicles V stored in the plurality of soak chambers S2.

[0024] The vehicle management device 30 is a general-purpose or dedicated computer equipped with a CPU, a memory, a display, input means (such as a keyboard and a mouse), a communication interface, etc. Then, by causing the CPU and its peripheral devices to cooperate according to the vehicle management program stored in the memory, as shown in FIG. 2, it functions as a surrounding temperature acquisition unit 31, a vehicle temperature acquisition unit 32, a position information acquisition unit 33, a recording unit 34, etc. Note that the vehicle management device 30 may be a portable mobile terminal such as a smartphone or a tablet terminal. Hereinafter, each part will be described while also explaining the operation of the vehicle management device 30.

[0025] The surrounding temperature acquisition unit 31 acquires the temperature detected by the first temperature sensor T1 together with the room identifier indicating the soak chamber S2 in which the first temperature sensor T1 is provided, and acquires the temperature as the temperature around the test vehicle V stored in the soak chamber S2 (hereinafter referred to as the surrounding temperature). Note that the communication between the surrounding temperature acquisition unit 31 and the first temperature sensor T1 can utilize various communication networks such as wireless communication and public lines.

[0026] In the present embodiment, as shown in FIG. 1, the first temperature sensor T1 is also provided in the test chamber S1 for testing the test vehicle V. Then, the surrounding temperature acquisition unit 31 acquires the temperature detected by the first temperature sensor T1 provided in the test chamber S1 together with the room identifier indicating the test chamber S1, and acquires the temperature as the surrounding temperature of the test vehicle V being tested in the test chamber S1.

[0027] 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 on which the second temperature is mounted, and acquires the temperature as the temperature of the test vehicle V (hereinafter referred to as the vehicle temperature). Note that the communication between the vehicle temperature acquisition unit 32 and the second temperature sensor T2 can utilize various communication networks such as wireless communication and public lines.

[0028] 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 position of the test vehicle V indoors. Here, as the position information, room identifiers indicating the soak chamber S2 and the test chamber S1 are used. In addition to, or instead of, the room identifier, the position information of the test vehicle V acquired from GPS may be used.

[0029] In the present embodiment, as shown in FIG. 1, each test vehicle V is equipped with a beacon transmitter B1 that transmits a beacon signal, and a beacon receiver B2 that receives this beacon signal is provided in the soak chamber S2 and the test chamber S1. The beacon signal includes identification information for identifying the beacon transmitter B1, and this identification information is associated with the vehicle identifier on which the beacon transmitter B1 is mounted.

[0030] 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 also acquires, as position information, the room identifier indicating the soak chamber S2 or the test chamber S1 in which the beacon receiver B2 is provided. Note that communication between the position information acquisition unit 33 and the beacon receiver B2 can utilize various wireless communications such as wireless LAN.

[0031] The recording unit 34 records the ambient temperature of the test vehicle V and the position information of the test vehicle V in association with each other in a predetermined area of the memory. Note that the recording unit 34 is not limited to recording in the memory provided in the vehicle management device 30, and may record in an external memory such as a cloud, a USB memory, or an SD card, for example.

[0032] Specifically, the recording unit 34 compares the vehicle identifier acquired by the ambient temperature acquisition unit 31 along with the ambient temperature of the test vehicle V with the vehicle identifier acquired by the location information acquisition unit 33 along with the location information of the test vehicle V, and if these vehicle identifiers match, associates the ambient temperature with the location information and records them. Note that the recording unit 34 may also associate the vehicle identifier of the test vehicle V with the ambient temperature of the test vehicle V and the location information of the test vehicle V and record them in memory.

[0033] More specifically, the recording unit 34 associates and records, for example, time-series data of the ambient temperature and time-series data of the location information. In this case, the time-series data of the ambient temperature and the time-series data of the location information may be linked by time, whereby the ambient temperature and the location information acquired by the location information acquisition unit 33 at the time the ambient temperature acquisition unit 31 acquired the ambient temperature are linked and recorded. Note that the recording unit 34 may also associate and record in memory the time information when the ambient temperature of the test vehicle V and the location information of the test vehicle V were acquired.

[0034] In this embodiment, the recording unit 34 is configured to record the ambient temperature of the test vehicle V and the location information of the test vehicle V, as well as the vehicle temperature acquired by the vehicle temperature acquisition unit 32 in association with a vehicle identifier indicating the test vehicle V. Note that if the first temperature sensor T1 in the test chamber S1 or the soak chamber S2 does not function due to a malfunction or the like, the memory unit 32 may record the vehicle temperature of the test vehicle V, the location information of the test vehicle V, and the vehicle identifier of the test vehicle V in association with each other. Specifically, the recording unit 34 associates the time series data of the ambient temperature, the time series data of the location information, and the time series data of the vehicle temperature, and specifically, as in the above-mentioned embodiment, the time series data may be linked by time. In this case, the ambient temperature, the location information acquired by the location information acquisition unit 33 at the time the ambient temperature acquisition unit 31 acquired the ambient temperature, and the vehicle temperature acquired by the vehicle temperature acquisition unit 32 at the same time are linked and recorded. In other words, the recording unit 34 stores this mutually related information in a database.

[0035] The vehicle management device 30 here is provided with an output unit 35 that 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 to, for example, the display of the vehicle management device 30 or the display of a portable mobile terminal such as a smartphone or tablet terminal separate from the vehicle management device 30. Here, the vehicle temperature associated with the ambient temperature and position information is further output in a comparable manner. Note that the output unit 35 may output the database recorded by the recording unit 34 as a list, or may be able to extract the ambient temperature or vehicle temperature of the test vehicle V associated with these using the vehicle identifier, position information, time information, etc. as keys from the database. Also, the output unit 35 can take out the database recorded in the recording unit 34 to other servers etc. via communication means using wire or wireless or an external memory.

[0036] According to the vehicle management device 30 configured in this way, since the ambient temperature of the test vehicle V and the position information of the test vehicle V are recorded in association, an exhaust gas analysis system 100 capable of acquiring the temperature traceability of the test vehicle V can be constructed.

[0037] Also, since the vehicle management device 30 acquires not only the ambient temperature of the test vehicle V but also the vehicle temperature of the test vehicle V, it is possible to grasp the temperature difference etc. and not only acquire the temperature traceability of the test vehicle V but also check whether the test vehicle V is temperature-controlled to a predetermined temperature in the soak chamber S2.

[0038] Note that the present invention is not limited to the above-described embodiment.

[0039] For example, in the above embodiment, the ambient temperature, location information, and vehicle temperature of the test vehicle V are recorded in association with each other, but it is not necessary to associate the vehicle temperature. In this case, it is not necessary to provide the second temperature sensor T2 on the test vehicle V, and the vehicle management device 30 is not required to have the function of the vehicle temperature acquisition unit 32.

[0040] The soak chamber S2 may be provided with a plurality of first temperature sensors T1 and a plurality of beacon receivers B2. In this embodiment, the location information acquisition unit 33 may be configured to identify the beacon receiver B2 that received the beacon signal transmitted from the beacon transmitter B1 mounted on the test vehicle V from among multiple beacon receivers B2 installed in the soak chamber S2. As a result, the location information acquisition unit 33 can acquire the installation location of the identified beacon receiver B2 in the soak chamber S2 as location information indicating the detailed location of the test vehicle V in the soak chamber S2. In such a 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 location of the test vehicle V acquired by the location information acquisition unit 33. With this configuration, even if the soak chamber S2 is large and the temperature varies depending on the location, it is possible to obtain an accurate ambient temperature of the test vehicle V.

[0041] In addition, in the above embodiment, a case was described in which the beacon transmitter B1 was mounted on the test vehicle V and the beacon receiver B2 was provided in the soak chamber S2 or the test chamber S1, but the beacon transmitter B1 may be provided in the soak chamber S2 or the test chamber S1 and the beacon receiver B2 may be mounted on the test vehicle V.

[0042] Furthermore, as shown in FIG. 3, a third temperature sensor T3 may also be provided in, for example, an outdoor parking lot where the test vehicle V is parked. In this case, the location information acquisition unit 33 may acquire the location information of the test vehicle V from a GPS. In such a configuration, as the recording unit 34, the ambient temperature of the test vehicle V parked in the parking lot may be acquired from the third temperature sensor T3, and the ambient temperature and the position information acquired from the GPS of the test vehicle V may be recorded in association with each other. With such a 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 as the temperature traceability of the test vehicle V.

[0043] Moreover, the vehicle temperature acquisition unit 32 may acquire the vehicle temperature from the test vehicle V parked in the parking lot. In this case, the position information acquisition unit 33 may acquire the position information of the test vehicle V from the GPS. In such a 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. Note that in this case, it is not necessary to provide the third temperature sensor T3 shown in FIG. 3 in the parking lot.

[0044] In addition, as shown in FIG. 4, the vehicle management device 30 includes a remaining capacity acquisition unit 36 that acquires the remaining capacity of the battery mounted on the test vehicle V, and the recording unit 34 may be configured to further record the remaining capacity acquired by the remaining capacity acquisition unit 36 in association with the ambient temperature of the test vehicle V and the position information of the test vehicle V. Although not shown, the vehicle management device 30 may include an analysis result acquisition unit that acquires the analysis result of the exhaust gas analyzer 20, and the recording unit 34 may be configured to record the analysis result acquired 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. With such a configuration, not only the ambient temperature of the test vehicle V but also a wide range of traceability including the remaining capacity of the battery, the exhaust gas measurement result, etc. can be acquired.

[0045] Furthermore, the output section 35 of the above embodiment may 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 manner that allows them to be compared. In addition, the vehicle management device 30 may further have the function of an alarm unit that compares the ambient temperature of the test vehicle V with the vehicle temperature of the test vehicle V and notifies the user if the temperature difference between these exceeds a predetermined threshold. With this configuration, it is possible to know, for example, any problems with the temperature control of the soak chamber S2.

[0046] Furthermore, the vehicle management device 30 according to the present invention may be configured to record the air pressure of the tires of the test vehicle V, as shown in FIG. Specifically, as shown in Figure 5, a configuration is possible in which, for example, a portable or stationary computer C reads a barcode or QR code attached to a test vehicle V to obtain the vehicle identifier of the test vehicle V, and the vehicle identifier and the results of measuring the tire air pressure of the test vehicle V are associated with each other and recorded in the memory of the vehicle management device 30.

[0047] For example, when recording tire air pressure, one embodiment is to measure the air pressure of the front, rear, left and right tires of the test vehicle V using an air pressure sensor S1 or the like, and transmit the air pressure data indicating the measurement results to the computer C via wireless communication or the like. At this time, for example, a measurement screen shown in FIG. 6 may be displayed on the display of the computer C. Specifically, measurement start buttons (F-L, F-R, R-L, R-R) for measuring the air pressure of each of the front, rear, left, and right tires are displayed before, after, to the left, and to the right of the vehicle symbol indicating the test vehicle. Then, when the input start button corresponding to the tire to be measured is pressed and the air pressure of that tire is measured by the air pressure sensor S1, the measured value is transmitted to the computer C and graphically displayed on the display of the computer C. The computer C determines the measured value as air pressure data and displays it, for example, in a measurement result display area set near the measurement start button. The air pressure data of each tire measured in this way is associated with a 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 predetermined area of the memory in association with each other. Note that the measurement date and time of the air pressure and the position information of the test vehicle V when the air pressure is measured may be associated with and managed together with the air pressure data and the vehicle identifier.

[0048] As a method of managing the above-described air pressure data by the vehicle management device 30, for example, a method may be employed in which barcodes, QR codes, etc. displayed on the display of the portable computer C are read by a reading device provided in the vehicle management device 30 so that various data is output to the vehicle management device 30. However, a method of outputting various data to the vehicle management device 30 by wire, wireless, etc. may also be acceptable.

[0049] Furthermore, the vehicle management device 30 according to the present invention may manage fuel information regarding the fuel filled in the test vehicle V in association with the vehicle identifier of the test vehicle V. Specifically, fuel information indicating the type and / or filling amount of fuel 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. Note that the filling date and time of the fuel and the position information of the test vehicle V may be managed in association with the fuel information and the vehicle identifier. Note that the fuel information may be obtained, for example, by reading a barcode, a QR code, or the like provided on a fuel filling facility, a fuel container, or the like.

[0050] In addition, when the test vehicle V is an electric vehicle or a hybrid vehicle, the vehicle management device 30 may manage charge data indicating the remaining capacity (SOC: State Of Charge) of the battery of the test vehicle V in association with the vehicle identifier of the test vehicle V. Specifically, the charge 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. Note that the charge date and time and the position information of the test vehicle V may be managed in association with the charge data and the vehicle identifier.

[0051] Furthermore, the vehicle management device 30 may manage vehicle weight data indicating the weight of the test vehicle V in association with the vehicle identifier of the test vehicle V. 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. Note that the measurement date and time of the vehicle weight and the position information of the test vehicle V where the vehicle weight is measured may be managed in association with the vehicle weight data and the vehicle identifier.

[0052] Needless to say, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit thereof.
