[0004] For example, when estimating energy consumption, such as the electricity consumption of electric vehicles or the fuel economy of engine vehicles, it is necessary to estimate the amount of energy consumed by individual components, such as the bodywork, at a lower cost in addition to estimating the amount of energy consumed by the vehicle itself while it is running.

[Figure 6] FIG. 10 is a schematic diagram showing a garbage truck including a garbage truck garbage consumption energy amount output device according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] In this embodiment, what is called dust is referred to as "garbage" or "trash," but these have the same meaning.

[0010] (First embodiment) A system for outputting the amount of consumed energy (hereinafter mainly referred to as the system) 1 for mounting a refuse compactor 2 according to a first embodiment will be described with reference to FIGS. 1 to 5. FIG.

[0011] Fig. 1 is a schematic diagram of a system 1 according to a first embodiment of the present invention. The graph in Fig. 1 shows the relationship between the operating time of the garbage collection unit 26 mounted on the garbage truck 2 when collecting garbage and the amount of energy consumed when collecting garbage, and the relationship between the operating time of the garbage collection unit 26 mounted on the garbage truck 2 when discharging garbage and the amount of energy consumed when discharging garbage. Fig. 2 is a schematic diagram of a garbage truck (compactor truck) 2. Fig. 3 is a diagram showing the processing flow of the system 1.

[0012] As shown in FIG. 1, the system 1 includes n (n is an integer greater than or equal to 1) garbage trucks 2a to 2n and an information processing server 3 (an energy consumption output device for the garbage truck 2) that can communicate with the garbage trucks 2a to 2n via a network N.

[0013] In the following description, when the n refuse trucks 2a to 2n are described without distinction, some of the reference numerals will be omitted and they will simply be referred to as "refuse truck 2." It is preferable that the refuse trucks 2a to 2n are refuse trucks of the same model and have the same body, but they may also be refuse trucks of different models but have the same body. Furthermore, even if the refuse trucks 2a to 2n are refuse trucks of different models and have different bodywork, they may be refuse trucks to which the relationship shown in the graph of the amount of energy consumed by the collection body and the amount of energy consumed by the discharge body shown in Figure 1 can be applied.

[0014] As shown in Figures 1 and 2, the garbage truck 2 has, in addition to a cab 12 and a chassis 14, an ECU (Electronic Control Unit) 16, a communication unit 18, a battery 20, a motor 22, a garbage storage unit 24, and a garbage collection unit 26.

[0015] The refuse truck 2 according to this embodiment may be, for example, an engine vehicle such as a diesel engine vehicle, HEV vehicle, PHEV vehicle, or FCEV vehicle, or an EV vehicle. Here, the refuse truck 2 is described as an EV vehicle, with an ECU 16, a communication unit 18, a battery 20, a motor 22, a refuse storage unit 24, and a refuse collection unit 26 mounted on a chassis 14. Of these, the refuse storage unit 24 and the refuse collection unit 26 are mounted as bodywork on the truck.

[0016] The ECU 16 is a computer for the garbage truck 2 that has a control unit that controls each part of the garbage truck 2. For example, the ECU 16 is made up of electronic circuits such as one or more processors, such as a CPU. The ECU (processor) 16 controls the overall operation of the garbage truck 2 in accordance with programs stored in a memory unit possessed by the ECU 16. The ECU (processor) 16 executes various programs stored in the memory unit of the ECU 16 to realize appropriate functions and perform various operations.

[0017] There may be one ECU 16 per refuse truck 2, or there may be multiple ECUs 16, one for controlling the various parts of the refuse truck 2 related to vehicle travel and one for controlling the equipment such as the refuse collection unit 26. For simplicity of explanation, the following will explain an example in which there is one ECU 16 per refuse truck 2. Note that even if there are separate ECUs 16, one for controlling the various parts of the refuse truck 2 related to vehicle travel and one for controlling the equipment such as the refuse collection unit 26, they will still control the refuse truck 2 in the same way as when there is one ECU.

[0018] The communication unit 18 transmits and receives various information signals relating to the refuse compactor 2 to and from the server (computer) 3 of the system 1 via the network N.

[0019] The battery 20 supplies appropriate power controlled by the ECU 16 to the ECU 16, the communication unit 18, the motor 22, the garbage collection unit 26, and other mounted components.

[0020] The motor 22 is used as a drive source for moving the wheels 14 a of the garbage compactor 2 using power from the battery 20 .

[0021] The dust storage section 24 is provided, for example, between the cab 12 and the dust collection section 26, and is formed as a container for storing dust.

[0022] The garbage collection unit 26 operates its hydraulic device using power from the battery 20 to store garbage in the garbage storage unit 24. Depending on the type of garbage collection unit 26 of the garbage truck 2, the garbage collection unit 26 can also operate its hydraulic device using power from the battery 20 to discharge garbage from the garbage storage unit 24 to the outside of the garbage truck 2.

[0023] For simplicity of explanation, it is assumed here that the garbage collection unit 26 mounted on the garbage truck 2 can be switched between a collection mode in which garbage is stored in the garbage storage unit 24, and a discharge mode in which the garbage stored in the garbage storage unit 24 is discharged to the outside. The garbage truck 2 is equipped with a switch for operating the hydraulic device of the garbage collection unit 26 in the collection mode, and a switch for operating the hydraulic device of the garbage collection unit 26 in the discharge mode. The ECU 16 controls the switches so that even if the collection mode switch and the discharge mode switch are pressed simultaneously, these operations are not performed simultaneously.

[0024] In the collection mode, the refuse truck 2's body (the hydraulic device of the refuse collection section 26) is operated to collect refuse at one or more locations.

[0025] In the collection mode, the mechanism of the dust collection unit 26 when storing dust in the dust storage unit 24 may be, for example, a winding type (rotating plate type), a press type (compression plate type), or a rotary type using a drum, and any of these may be used. If the relationship of the graph of the amount of energy consumed when collecting dust shown in Figure 1 differs depending on these methods, a graph corresponding to each method may be prepared. Note that in this embodiment, the mechanism of the dust collection unit 26 in the collection mode is a rotary type.

[0026] In this embodiment, in the discharge mode, for example at a garbage incineration plant, the garbage truck 2's body (for example, the hydraulic device of the garbage collection section 26) is moved to sequentially discharge the garbage stored in the garbage storage section 24 to the outside of the garbage truck 2.

[0027] In the discharge mode, the mechanism for discharging the garbage from the garbage storage unit 24 may be any of the following: a rotary type that reverses the rotation of the drum described above, a push type that moves a discharge plate (not shown), or a dump type that lifts the garbage storage unit 24 using a hoist mechanism (not shown). In this embodiment, the mechanism in the discharge mode is a rotary type that moves the hydraulic device of the garbage collection unit 26.

[0028] The operating time of the garbage collection unit 26 in the collection mode and discharge mode is the time when the garbage collection worker presses the switch of the garbage collection unit 26 and the hydraulic device of the garbage collection unit 26 operates using power from the battery 20.

[0029] The garbage truck 2 consumes energy (electricity) from the battery 20, for example, when it moves to one or more locations to collect garbage, when it moves to a garbage incineration plant or the like to discharge the garbage after collecting the garbage, and when the garbage collection unit 26, which is mounted on it, is operating (when collecting and discharging).

[0030] FIG. 1 is a block diagram showing a schematic configuration example of an information processing server 3 according to this embodiment.

[0031] The server 3 is a computer including a control unit 31, a storage unit 32, and a communication unit 33. The control unit 31, the storage unit 32, and the communication unit 33 are connected to each other via a bus line.

[0032] The control unit 31 controls the overall operation of the information processing server 3 in accordance with the programs stored in the storage unit 32. For example, the control unit 31 is configured with electronic circuits such as one or more processors. The control unit 31 is assumed to be, for example, a CPU. The control unit 31 executes various programs stored in the storage unit 32 to realize appropriate functions and perform various operations.

[0033] The memory unit 32 is composed of a main memory and an auxiliary memory. For example, the main memory is composed of a volatile memory that provides a working area for the processor. For example, the main memory is composed of a RAM (Random Access Memory) or the like. For example, the auxiliary memory is composed of a non-volatile memory that stores various information and programs for the operation of the information processing server 3. For example, the auxiliary memory is composed of an HDD (Hard Disk Drive) or an SSD (Solid State Drive) or the like. The memory unit 32 stores programs that cause the control unit 31 to realize various functions. The memory unit 32 stores, for example, information shown in the graph in FIG. 1 that is provided via the network N. In this embodiment, the memory unit 32 stores, for example, a processing program for outputting the amount of energy consumed by the garbage truck 2, which is executed by the control unit 31. It is preferable that the memory unit 32 also stores an output of the estimated energy consumption amount, which will be described later, for each garbage truck 2.

[0034] FIG. 1 shows a graph with the operating time of the hydraulic device of the garbage collection unit 26 as a mounted unit on the horizontal axis and the energy consumption of the mounted unit during garbage collection on the vertical axis, and a graph with the operating time of the garbage collection unit 26 as a mounted unit on the horizontal axis and the energy consumption of the mounted unit during garbage discharge on the vertical axis. The data on the energy consumption of the collection unit shown in FIG. 1 is an example of the relationship between the operating time of the mounted unit and the energy consumption when household garbage is collected from multiple locations along a certain route using the hydraulic device of the garbage collection unit 26 mounted on one or more garbage trucks 2. The data on the energy consumption of the discharge unit shown in FIG. 1 is an example of the relationship between the operating time of the mounted unit and the energy consumption when household garbage is collected from multiple locations along a certain route using the hydraulic device of the garbage collection unit 26 mounted on one or more garbage trucks 2 and then discharged. Here, for example, linear approximation lines are set for the data on the amount of energy consumed by the collection body and the data on the amount of energy consumed by the discharge body. The server (the refuse compactor 2 body energy consumption amount output device) 3 outputs the estimated amount of energy consumed for the actual operating time based on these approximation lines.

[0035] The relationship shown in the two graphs in Figure 1 is an example and may change depending on the type of garbage, etc. For example, the types of household garbage differ depending on the local government, and can be divided into, for example, plastics, PET bottles, metals, paper, and others. Therefore, the operating time of the equipment when collected by the garbage compactor 2 varies depending on the type of garbage separated.

[0036] 1, the data on the collected equipment energy consumption amount and the data on the discharged equipment energy consumption amount are preferably acquired in advance by the server 3 via the network N and stored in the storage unit 32. Alternatively, the data may be stored in a server other than the server 3 so that the server 3 acquires the data via the network N when outputting the energy consumption amount. For example, after being acquired by the server 3, the data may be stored in the storage unit 32 of the server 3, for example.

[0037] The communication unit 33 is configured with one or more communication interfaces capable of performing communication conforming to any wireless communication standard. The communication unit 33 includes one or more communication interfaces capable of performing communication between the information processing server 3 and the garbage truck 2 via the network N as described above.

[0038] The hardware configuration of the information processing server 3 is not limited to the above configuration. The information processing server 3 allows the omission or modification of the above components and the addition of new components as appropriate.

[0039] The system 1 is a so-called client-server system. The system 1 is realized by mutual communication between the ECUs 16 of n refuse trucks 2, which are clients, and the server 3 via a network N and communication units 18 and 33. The network N may be realized by, for example, the Internet, a network such as a mobile phone network, a LAN (Local Area Network), or a network that combines these.

[0040] The process of outputting the amount of energy consumed by the garbage compactor 2, which is implemented by the control unit 31 of the information processing server 3, will be described with reference to Fig. 3. Note that each process implemented by the control unit 31 here can also be said to be implemented by a computer including a processor.

[0041] For example, at a certain first garbage collection location, an operator of the garbage truck 2 places an appropriate amount of garbage in the garbage collection unit 26 and presses the collection mode switch to operate the hydraulic device of the garbage collection unit 26. When the garbage collection unit 26 operates to store the garbage in the garbage storage unit 24, the operator switches the collection mode switch to OFF, stopping the operation of the hydraulic device of the garbage collection unit 26. The ECU 16 transmits, via the communication unit 18, to the information processing server 3, information on the start time (start time) and stop time (stop time) of the operation of the hydraulic device of the garbage collection unit 26 in the collection mode of the garbage truck 2, or information on the actual operating time of the hydraulic device of the garbage collection unit 26 based on the difference between the start time (start time) and stop time (stop time). In other words, the server 3 obtains the operating time of the garbage truck 2's equipment when the garbage truck 2 processes garbage. Here, it is assumed that the EUC 16 transmits information on the actual operating time of the hydraulic device of the latter garbage collection unit 26. The server 3 determines whether the information from the garbage truck 2 indicates operation in collection mode (step S1).

[0042] If the server 3 determines that the collection mode has been selected (executed) in the garbage truck 2 (step S1-Yes), the server (the device for outputting the amount of energy consumed by the equipment of the garbage truck 2) 3 reads the relationship shown in the graph from the storage unit 32 in response to the input of the actual operating time of the equipment when collecting garbage in the garbage truck 2, or obtains the relationship shown in the graph via the network N, and outputs the estimated amount of energy consumed corresponding to the actual operating time of the equipment when collecting garbage in the garbage truck 2. Therefore, the server 3 outputs the amount of energy consumed when the garbage truck 2 processes garbage based on the information showing the relationship between the operating time of the equipment and the amount of energy consumed by the equipment for processing garbage and the obtained operating time. That is, the server 3 outputs the estimated amount of energy consumed corresponding to the actual operating time of the hydraulic device of the garbage collection unit 26, which is the equipment, based on the input of information about the actual operating time of the hydraulic device of the garbage collection unit 26, which is the equipment, from the ECU 16 of the garbage truck 2 (step S2). This output is stored in the storage unit 32 of the server 3, for example.

[0043] Furthermore, when the ECU 16 transmits to the server 3 information on the start time (start time) and stop time (stop time) of the operation of the hydraulic device of the garbage collection unit 26 in the collection mode of the garbage truck 2, it can be said that the actual operation time of the hydraulic device of the garbage collection unit 26 is input to the control unit 31 of the server 3.

[0044] Furthermore, at a second garbage collection site, the operator of the garbage truck 2 places an appropriate amount of garbage in the garbage collection unit 26 and presses the collection mode switch to operate the hydraulic device of the garbage collection unit 26. The server 3 determines whether the next mode executed by the garbage truck 2 is the discharge mode (step S3). If it is determined in step S3 that the discharge mode has not been selected (step S3-No), the process returns to step S1. Therefore, the server 3 outputs the estimated energy consumption amount of the hydraulic device of the garbage collection unit 26 in the collection mode at each garbage collection site until the discharge mode switch is switched ON.

[0045] Therefore, the device for outputting the amount of energy consumed by the body of the garbage truck 2 is, for example, the server 3, and the server 3 acquires the operating time of the body of the garbage truck 2 taken when the garbage truck 2 processes (e.g., collects) garbage, and outputs the amount of energy consumed when the garbage truck 2 processes the garbage based on the acquired operating time and information showing the relationship between the operating time of the body and the amount of energy consumed by the body when processing the garbage. Also, the method for outputting the amount of energy consumed by the body of the garbage truck 2 includes acquiring the operating time of the body of the garbage truck 2 taken when the garbage truck 2 processes (e.g., collects) garbage, and outputting the amount of energy consumed when the garbage truck 2 processes the garbage based on the acquired operating time and information showing the relationship between the operating time of the body and the amount of energy consumed by the body when processing the garbage. At this time, the server (a device for outputting the amount of energy consumed by the attachment of the garbage truck 2) 3 reads out the above-mentioned relationship from the memory unit 32 in response to an input of the actual operating time of the attachment for processing (e.g., during collection) garbage in the garbage truck 2, or acquires the above-mentioned relationship via the network N, and outputs an estimated amount of energy consumed corresponding to the actual operating time of the attachment for processing (e.g., during collection) garbage in the garbage truck 2. More specifically, the above-mentioned relationship is read out from the memory unit 32 of the server 3, or acquired by the server 3 via the network N, and an estimated amount of energy consumed by the attachment of the garbage truck 2 corresponding to the actual operating time of the attachment for processing (e.g., during collection) garbage is output in response to an input of the actual operating time of the attachment for processing (e.g., during collection), and the program for estimating the amount of energy consumed by the attachment of the garbage truck 2 causes the control unit (computer) 31 of the server 3 to execute such processing.

[0046] Each time step S2 is executed, the server 3 outputs not only the amount of energy consumed by the body of the garbage truck 2 at each garbage collection point, but also the cumulative amount of energy consumed. These outputs are stored, for example, in the memory unit 32 of the server 3. The outputs relating to the individual amounts of energy consumed and the cumulative amount of energy consumed can be read by users of the server 3.

[0047] For example, after collecting garbage at all scheduled garbage collection locations, the operator of the garbage truck 2 presses the discharge mode switch at a location where garbage is to be discharged, such as a garbage incineration plant, to operate the hydraulic device of the garbage collection unit 26. When the operator determines that all of the garbage contained in the garbage collection unit 24 has been discharged outside the garbage truck 2 through the garbage collection unit 26, he or she switches the discharge mode switch to OFF, thereby stopping the operation of the hydraulic device of the garbage collection unit 26. The ECU 16 transmits, via the communication unit 18, to the information processing server 3, information on the start time (start time) and stop time (stop time) of the operation of the hydraulic device of the garbage collection unit 26 in the discharge mode of the garbage truck 2, or information on the actual operating time of the hydraulic device of the garbage collection unit 26 based on the difference between these start time (start time) and stop time (stop time). That is, the server 3 acquires the operating time of the equipment of the garbage truck 2 when the garbage truck 2 processes garbage. Here, the ECU 16 transmits information on the actual operating time of the hydraulic device of the latter garbage collection unit 26. The server 3 determines whether the information from the garbage truck 2 indicates operation in discharge mode (step S3).

[0048] If the server 3 determines that the discharge mode has been selected (executed) in the garbage truck 2 (step S3-Yes), the server (the device for outputting the amount of energy consumed by the equipment of the garbage truck 2) 3 reads the relationship shown in the graph from the memory unit 32 in response to the input of the actual operating time of the equipment when discharging garbage from the garbage truck 2, or obtains the relationship shown in the graph via the network N, and outputs the estimated amount of energy consumed corresponding to the actual operating time of the equipment when discharging garbage from the garbage truck 2. Therefore, the server 3 outputs the amount of energy consumed when the garbage truck 2 processes garbage based on the information showing the relationship between the operating time of the equipment and the amount of energy consumed by the equipment for garbage processing and the obtained operating time. That is, the server 3 outputs the estimated amount of energy consumed corresponding to the actual operating time of the hydraulic device of the garbage collection unit 26, which is the equipment, based on the input of information about the actual operating time of the hydraulic device of the garbage collection unit 26, which is the equipment, from the ECU 16 of the garbage truck 2 (step S4). This output is stored, for example, in the storage unit 32 of the server 3. The output relating to the amount of energy consumed when disposing of the garbage and the output relating to the cumulative amount of energy consumed in the series of garbage collection and disposal can be read by users of the server 3.

[0049] Furthermore, when the ECU 16 transmits to the server 3 information on the start time (start time) and stop time (stop time) of the operation of the hydraulic device of the garbage collection unit 26 in the discharge mode of the garbage truck 2, it can be said that the actual operation time of the hydraulic device of the garbage collection unit 26 is input to the control unit 31 of the server 3.

[0050] Therefore, the server (energy consumption output device) 3 of the garbage truck 2's mounting acquires the operating time of the garbage truck 2's mounting when the garbage truck 2 processes (e.g., discharges) garbage, and outputs the amount of energy consumed when the garbage truck 2 processes garbage based on the acquired operating time and information indicating the relationship between the mounting's operating time and the amount of energy consumed by the mounting when processing garbage. Also, a method for outputting the amount of energy consumed by the garbage truck 2's mounting includes acquiring the operating time of the garbage truck 2's mounting when the garbage truck 2 processes (e.g., discharges) garbage, and outputting the amount of energy consumed when the garbage truck 2 processes garbage based on the acquired operating time and information indicating the relationship between the mounting's operating time and the amount of energy consumed by the mounting when processing garbage. At this time, the server (a device for outputting the amount of energy consumed by the attachment of the garbage truck 2) 3 reads out the above-mentioned relationship from the memory unit 32 in response to an input of the actual operating time of the attachment for processing (e.g., discharging) the garbage from the garbage truck 2, or acquires the above-mentioned relationship via the network N, and outputs an estimated amount of energy consumed corresponding to the actual operating time of the attachment for processing (e.g., discharging) the garbage from the garbage truck 2. More specifically, the program for outputting the amount of energy consumed by the attachment of the garbage truck 2 reads out the above-mentioned relationship from the memory unit 32 of the server 3, or acquires it via the network N, and outputs an estimated amount of energy consumed by the attachment corresponding to the actual operating time of the attachment in response to an input of the actual operating time of the attachment for discharging the garbage, and causes the control unit (computer) 31 of the server 3 to execute such processing.

[0051] After estimating the amount of energy consumed when discharging garbage, if the server 3 determines in step S1 that the collection mode of the garbage truck 2 was not selected (step S1-No), it determines whether the discharge mode was selected (step S5).If the server 3 determines that the discharge mode was selected (step S5-Yes), it performs the process of step S4.

[0052] If the server 3 determines in step S5 that the discharge mode has not been selected (step S5-No), the server 3 ends the process of outputting the energy consumption of the hydraulic device of the garbage collection unit 26 of the garbage truck 2.

[0053] 3 is an example of the processing flow by the control unit 31 of the server 3, and other processing flows are also permissible. For example, the control unit 31 of the server 3 may obtain the ON / OFF signals of the collection mode and discharge mode switches of each garbage truck 2 via the communication unit 18 controlled by the ECU 16 of each garbage truck 2, determine the actual operating time of the hydraulic device of the garbage collection unit 26 in the collection mode / discharge mode of that garbage truck 2, and output the estimated amount of energy corresponding to each operating time based on the relationship shown in the graph in FIG.

[0054] Therefore, the server 3 can estimate the amount of energy consumed in garbage disposal (when collecting and / or discharging) using the garbage truck 2 from the actual operating time of the equipment of the garbage truck 2. In other words, the server 3 can output the amount of energy consumed by the equipment of the garbage truck 2 when disposing of garbage.

[0055] The server 3 can collect operating time information about the refuse truck 2's mounting and output the amount of energy consumed by the mounting. By outputting the amount of energy consumed when the refuse truck 2 is running, it is possible to predict the total energy consumption of the refuse truck 2, including the mounting of the refuse truck 2, and the electricity cost. Furthermore, when providing support for the introduction of the refuse truck 2, a user of the server 3, such as a manufacturer of the refuse truck 2, can provide the user of the refuse truck 2 with the total energy consumption of the refuse truck 2 based on the information from the server 3 and make highly accurate suggestions such as the number of battery packs required for the refuse truck 2. Furthermore, when providing support for the operation of the refuse truck 2 to the user, the manufacturer of the refuse truck 2 can make suggestions such as highly accurate and efficient charging management and optimization of garbage collection routes.

[0056] According to this embodiment, it is possible to provide a garbage truck 2 mounting energy consumption output device (server) 3, a garbage truck 2 mounting energy consumption output method, and a garbage truck 2 mounting energy consumption output program, which can output the amount of energy consumed by the garbage truck mounting at a lower cost.

[0057] In this embodiment, an example has been described in which the server 3 acquires the actual operating time of the body from the ECU 16 online via the communication unit 18. The server 3 may also acquire the data offline by installing a data measuring device in the garbage compactor 2.

[0058] The horizontal axis of Figures 4 and 5 represents the actual measured amount of energy consumed by the body, and the vertical axis represents the amount of energy consumed by the body calculated using the server 3 based on the relationship of the graph of collected body energy consumption amount shown in Figure 1. The actual range of values ​​on the horizontal axis of Figures 4 and 5 is not shown, but is the same as each other. Also, the actual range of values ​​on the vertical axis of Figures 4 and 5 is not shown, but is the same as each other.

[0059] The oil temperature of the hydraulic system of the garbage collection unit 26 has an optimum temperature range. As shown in Figure 4, if the oil temperature of the hydraulic system of the garbage collection unit 26 is not taken into consideration, the error in the calculated energy consumption amount of the body relative to the actually measured energy consumption amount of the body will be larger than if the oil temperature of the hydraulic system of the garbage collection unit 26 is taken into consideration, as shown in Figure 5. By using data that takes oil temperature into consideration for the energy consumption amount of the body during garbage collection and the energy consumption amount of the body during garbage discharge shown in Figure 1, the energy consumption of the body can be output more accurately from the operation time of the body.

[0060] In addition, the amount of energy consumed by the equipment output by the server 3 may take into account increases or decreases in friction in the hydraulic system due to changes in oil temperature in the hydraulic device of the garbage collection section 26, and the effects of inching, which is the compression operation when the garbage storage section 24 is full of garbage.

[0061] In this embodiment, an example has been described in which a rotary-type attachment using a hydraulic device for the garbage collection unit 26 is used as the attachment for garbage discharge. When a push-out type attachment is used, the garbage collection unit 26 is rotated relative to the garbage storage unit 24, as shown by the two-dot chain line in FIG. 2, to open the garbage storage unit 24 and discharge the garbage with the discharge plate. When a dump-type attachment is used, the garbage storage unit 24 is tilted using a hoist mechanism, and the garbage collection unit 26 is rotated relative to the garbage storage unit 24 to open the garbage storage unit 24 and discharge the garbage. If the relationship shown in the graph of the amount of energy consumed when discharging garbage shown in FIG. 1 differs depending on these types, a graph of the relationship corresponding to each type can be prepared.

[0062] For example, when a dump type garbage truck 2 is used, the garbage storage section 24 and the garbage collection section 26 of the garbage truck 2 move between the positions indicated by the solid lines and the dashed lines in FIG. 2. The amount of energy consumed by the equipment when discharging garbage from the garbage truck 2 does not fluctuate as much as the amount of energy consumed when collecting garbage into the garbage truck 2. The amount of energy consumed at this time can be approximately constant. For this reason, the amount of energy consumed when discharging garbage shown in FIG. 1 may be set to a predetermined amount each time the garbage truck 2 is moved, regardless of the time. Therefore, the server 3 may provide a constant value for the amount of energy consumed by the equipment when discharging garbage from the garbage truck 2, without using the relationship shown in the graph in FIG. 1.

[0063] In this embodiment, an example has been described in which the refuse truck 2 is an electric vehicle and the energy is electric power from the battery 20. If the refuse truck 2 is not an electric vehicle but an engine vehicle such as a diesel vehicle, HEV vehicle, PHEV vehicle, or FCEV vehicle, a system called PTO (Power Take Off) that uses the engine's output to obtain electric power to operate the hydraulic device of the refuse collection unit 26 of the refuse truck 2, mainly when the refuse truck 2 is stopped. In such a case, if the refuse truck is an engine vehicle, diesel fuel, for example, is used as an energy source. Then, if the server 3 obtains a graph showing the relationship between the operating time of the PTO system and the amount of diesel fuel used as the energy source, it can output the amount of energy consumed (amount of fuel used) corresponding to the actual operating time of the PTO system. Therefore, in this case too, it is possible to provide a garbage truck 2 mounting energy consumption output device (server) 3, a garbage truck 2 mounting energy consumption output method, and a garbage truck 2 mounting energy consumption output program, which can output the amount of energy consumed by the garbage truck 2 mounting at a lower cost.

[0064] (Second embodiment) FIG. 6 is a schematic diagram showing a garbage truck 2 including an energy consumption amount output device (ECU) 16 mounted on the garbage truck 2 according to the second embodiment.

[0065] In the first embodiment, an example has been described in which the server 3 serves as a refuse truck 2 body-mounted energy consumption amount output device, and outputs the amount of energy consumed by each refuse truck 2 body from a series of refuse collection to refuse discharge.

[0066] The ECU 16 of the garbage truck 2 shown in Fig. 6 is used as an energy consumption amount output device for the garbage truck 2. For this reason, the ECU 16 of the garbage truck 2 shown in Fig. 6 may execute a program according to the flow shown in Fig. 3. In this case, when calculating the amount of energy consumed by the body, the ECU 16 may store the relationship between the operating time of the garbage collection unit 26 as the body and the amount of energy consumed, as shown in the graph in Fig. 1, in a memory unit of the ECU 16, read and output this from the memory unit, or obtain it via the communication unit 18 and output the estimated amount of energy consumed by the body. In this case, the energy consumption amount output device 16 of the garbage truck 2 and / or an energy consumption amount output program for the garbage truck 2 is stored in a memory unit of, for example, the ECU 16 of the garbage truck 2, and the program is executed by a control unit of the ECU 16.

[0067] According to this embodiment, it is possible to provide a garbage truck 2 mounting energy consumption output device (ECU) 16, a garbage truck 2, a garbage truck 2 mounting energy consumption output method, and a garbage truck mounting energy consumption output program, which can output the amount of energy consumed by the garbage truck 2 mounting at a lower cost.

Furthermore, the embodiments may be implemented in appropriate combinations, in which case the combined effects can be obtained. Furthermore, the above-described embodiments include various inventions, and various inventions can be extracted by combining selected elements from the disclosed elements. For example, if the problem can be solved and the desired effect can be obtained even if some elements are deleted from all elements shown in the embodiments, the configuration from which these elements are deleted can be extracted as an invention.
