Description

[Technical Field]

[0001] The present invention relates to a specially equipped vehicle that is equipped with an attached object that operates by receiving power from a power source. [Background technology]

[0002] Conventionally, there has been known a specially equipped vehicle that is equipped with a mounted object that operates by receiving power from a power source such as an engine, and an operating unit that operates the mounted object (see Patent Document 1). This specially equipped vehicle further includes a power take-off device that can connect or disconnect the engine and the mounted object, and the operating unit includes a variable resistance volume (input unit) that adjusts the rotation speed of the engine (power source) that drives the mounted object when the engine and the mounted object are connected by the power take-off device, and a control unit that controls the operation of the engine so that the engine rotation speed corresponds to the operating position when the volume is rotated.

[0003] In this specially equipped vehicle, when the mounted equipment is in operation, the volume is rotated to adjust the engine speed, thereby adjusting the amount of power transmitted from the engine (power source) to the mounted equipment. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-229857 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned specially equipped vehicles, there is only one control for the operation of the mounted equipment (control of the engine speed), but in specially equipped vehicles that have multiple controls for the operation of the mounted equipment (operation modes), for example, the same number of input units as the number of operation modes are arranged to adjust the power transmitted to the mounted equipment for each operation mode, which results in a large number of parts in the operating unit.

[0006] Therefore, an object of the present invention is to provide a specially equipped vehicle with a reduced number of parts. [Means for solving the problem]

[0007] The specially equipped vehicle of the present invention is A control unit that controls an attached object that operates using power from a power source, and has a plurality of operation modes that differ in control related to the operation; an input unit that inputs a value related to the operation mode into the control unit, The input unit is capable of inputting the value in each of the plurality of operation modes.

[0008] In this way, by making the input section for inputting the values ​​common to each operation mode (i.e., by making it one), the number of parts can be reduced.

[0009] In the specially equipped vehicle, the input unit has a rotary knob and a rotary encoder that detects a rotation angle of the rotary knob, The value may be at least one of an increase value and a decrease value according to the rotation angle of the mounted object relative to a predetermined set value.

[0010] By using a rotary encoder as the input unit in this way, at least one of an increase value and a decrease value can be input without returning the input unit to its initial position after each operation.

[0011] In these cases, for example, The mounted object has a tank for storing water, a water-discharging nozzle, and a pump for supplying water from the tank to the water-discharging nozzle, the pump is driven by the power source; The value may be at least one of the amount of water sprayed per unit area on the road surface from the water-discharge nozzle in one of the plurality of operating modes and an increase or decrease in the rotation speed of the pump in another of the plurality of operating modes.

[0012] Also, The mounted object has a hydraulic actuator and a hydraulic pump that operates the hydraulic actuator, the hydraulic pump is driven by the power source; The value may be at least one of an increase and a decrease in at least one of the magnitude of the power output from the power source and the discharge volume of the hydraulic pump. [Effects of the Invention]

[0013] As described above, according to the present invention, a specially equipped vehicle with a reduced number of parts can be provided. [Brief explanation of the drawings]

[0015] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0016] The specially equipped vehicle according to this embodiment is a sprinkler truck capable of sprinkling water on road surfaces while traveling on expressways and the like. As shown in Fig. 1, this sprinkler truck includes a chassis (not shown), a cab 2 disposed at the front of the chassis and equipped with an engine E / G as a driving source for traveling, and a sprinkler device (mounted) 3 mounted (mounted) on the chassis behind the cab 2. The sprinkler truck 1 also includes a vehicle speed sensor S1 that detects vehicle speed, and an ECU (engine control unit) 9 disposed between the engine E / G and an accelerator pedal 8 that controls the engine E / G based on accelerator pedal 8 opening information and speed information from the vehicle speed sensor S1. Note that in Fig. 1, reference numeral 10 denotes front wheels, and reference numeral 11 denotes rear wheels.

[0017] The sprinkler device 3 operates using power from a power source M. The sprinkler device 3 has a control unit 60 that has multiple operating modes that control the operation of the sprinkler device 3 differently, and a rotary operation unit (input unit) 64 that inputs values ​​related to the operating mode into the control unit 60 (see FIG. 2(a)).

[0018] Specifically, the sprinkler device 3 comprises a tank 4 mounted on the rear of the chassis for storing water to be sprayed, a sprinkler pump (pump) P for sucking in and pressurizing the water stored in the tank 4, water being pumped through piping (not shown) by driving the sprinkler pump P to spray water into water-discharging nozzles (not shown) that spray water in front of the sprinkler truck 1 and water-discharging nozzles (sprinkler nozzles) 5 that spray water behind the sprinkler truck 1, and an electric motor (power source) M that drives the sprinkler pump P. The sprinkler device 3 also comprises an operation panel 6 (see Figures 2(a) and 2(b)) and a controller 7 that controls the sprinkler device 3 based on inputs from the operation panel 6.

[0019] The watering pump P has a pump rotation speed sensor S2 that detects the rotation speed of the watering pump P, and outputs the rotation speed of the watering pump P detected by the pump rotation speed sensor S2 (rotation speed information) to the controller 7.

[0020] The controller 7 controls the electric motor M based on operation information from the operation panel 6 and information from the ECU 9. The controller 7 also constantly monitors the entire system of the sprinkler device 3, and if any abnormality is detected, takes measures such as issuing an alarm or stopping the system.

[0021] 2(a) and 2(b), the operation panel 6 has a control unit 60 having a memory unit 601, a box body 6B that houses the control unit 60 and has an opening at the front, and an operation panel 6A that covers the opening of the box body 6B. The operation panel 6 is disposed near the meter panel 12 (see FIG. 3) inside the driver's cab 2. The sprinkler device 3 can be operated using the operation panel 6 not only when the sprinkler truck 1 is stopped, but also when it is traveling.

[0022] The operation panel 6A has a selection operation unit 61 for selecting from multiple (three in this embodiment) operation modes that differ in control of the operation of the sprinkler device 3 (more specifically, the electric motor M), a lane width setting operation unit 62 for selecting the road width for sprinkling water on the road, a screen display switching operation unit 63 for switching the screen display of the meter panel 12, and a rotation operation unit (input unit) 64 for adjusting or inputting the amount of water sprinkled from the water-discharge nozzles 5. The operation panel 6A also has a Back switch 65 for use when a warning or error occurs, and an Enter switch 66 for confirming the selection made using the various operation units. This Enter switch 66 is also used when a warning or error occurs. In this embodiment, the selection operation unit 61 also serves as a start operation unit for starting the electric motor M. In other words, operating the selection operation unit 61 starts the electric motor M of the sprinkler device 3.

[0023] The selection operation unit 61 is a component for selecting one of a plurality of operation modes (vehicle speed synchronization mode, constant pump rotation mode, and manual operation mode). The selection operation unit 61 of this embodiment has a plurality of push-button switches 611, 612, and 613 (specifically, a number corresponding to the number of operation modes), and the operation mode to be executed by the sprinkler device 3 is selected (determined) by pressing the switch (vehicle speed synchronization switch 611, constant pump rotation switch 612, or manual switch 613) corresponding to the desired operation mode from the plurality of operation modes (vehicle speed synchronization mode, constant pump rotation mode, or manual operation mode). The selection operation unit 61 is located on the upper left side of the operation panel 6A, and the switches 611, 612, and 613 are arranged side by side on the selection operation unit 61.

[0024] The vehicle speed synchronization mode is a mode in which the amount of water sprayed per unit area on the road surface is constant in synchronization with the vehicle speed, and is selected by pressing the vehicle speed synchronization switch 611 of the selection operation unit 61. The constant pump rotation mode is a mode in which the rotation of the sprinkler pump P is maintained at a set rotation speed regardless of the engine rotation speed (vehicle speed), and is selected by pressing the constant pump rotation switch 612 of the selection operation unit 61. The manual operation mode is a mode used in emergencies such as when an abnormality occurs in the pump rotation speed sensor S2, and is selected by pressing the manual switch 613 of the selection operation unit 61. In this manual selection mode, the electric motor M is driven to rotate the sprinkler pump P at the output value set by the rotation operation unit 64, and therefore the controller 7 does not perform feedback control to maintain the rotation speed of the sprinkler pump P at the set target rotation speed. Information for executing the vehicle speed synchronization mode, the constant pump rotation mode, and the manual operation mode is stored in the control unit 60 (more specifically, the memory unit 601).

[0025] As described above, the control unit 60 has a plurality of operation modes (more specifically, information for executing the vehicle speed synchronization mode, the constant pump rotation mode, and the manual operation mode). When one of the three switches 611, 612, 613 of the selection operation unit 61 is pressed, the control unit 60 retrieves from the memory unit 601 the starting output value corresponding to the pressed switch 611, 612, 613 (operation mode), and starts the electric motor M with the retrieved starting output value. Therefore, regardless of the magnitude of the output value of the electric motor M at the end of the previous work, when starting the electric motor M during the next work, the control unit 60 starts the electric motor M with the starting output value stored in the memory unit 601.

[0026] The lane width setting operation unit 62 has three push-button switches (one-lane switch 621, two-lane switch 622, and three-lane switch 623) for selecting the lane width of the road. This lane width setting operation unit 62 is located in the vertical middle of the operation panel 6A, and the switches 621, 622, and 623 are arranged side by side in the lane width setting operation unit 62. In this lane width setting operation unit 62, the one-lane switch 621 is a switch that is pressed when sprinkling water on one lane of the road, the two-lane switch 622 is a switch that is pressed when sprinkling water on two lanes of the road, and the three-lane switch 623 is a switch that is pressed when sprinkling water on three lanes of the road. The sprinkler device 3 of this embodiment is configured to set the width of the sprinkler or change the amount of water to be sprayed (discharge volume of the sprinkler pump P) by selecting the number of lanes, but is not limited to this configuration and may be configured to be able to set the width of the sprinkler to any width or change the amount of water to be sprayed (discharge volume of the sprinkler pump P) to any amount.

[0027] The screen display switching operation unit 63 is a push-button switch located at the left end of the lower part of the operation panel 6A. This screen display switching operation unit 63 switches between the operation mode and the setting mode. In the sprinkler device 3 of this embodiment, after the screen display switching operation unit 63 is pressed to switch to the setting mode, the screens displayed on the display screen 12A of the meter panel 12 corresponding to each operation mode are switched sequentially each time the screen display switching operation unit 63 is pressed.

[0028] Specifically, after the screen display switching operation unit 63 is switched to the setting mode, it is pressed a predetermined number of times so that the display on the display screen 12A switches to the screen for the operation mode in which the user wishes to change the starting output value of the electric motor M. Then, the rotation operation unit 64 is operated to change the amount of water sprayed from the water-discharging nozzle 5 (amount of water discharged). After this change, the Enter switch 66 is pressed, and the starting output value of the electric motor M corresponding to the changed amount of water sprayed (amount of water discharged) is stored in the memory unit 601 in the operation panel 6.

[0029] Here, the values ​​set for each of the three operation modes in the setting mode are as follows: In the vehicle speed synchronization mode, the water spray amount per unit area (L / m 2 ) is the starting output value of the electric motor M relative to the rotation speed (rpm) of the watering pump P, and in the constant pump rotation mode, it is the starting output value of the electric motor M relative to the rotation speed (rpm) of the watering pump P, and in the manual operation mode, it is the starting output value of the electric motor M relative to the rotation speed (rpm) of the watering pump P.

[0030] By setting the starting output value of the electric motor M for each of these three operating modes, when either switch 612 or 613 of the selection operation unit 61 is pressed during the next or subsequent watering operation, the starting output value of the electric motor M set in the selected operating mode is retrieved from the memory unit 601, and the electric motor M is started at this retrieved starting output value.

[0031] Furthermore, when switch 611 is pressed, by pressing any one of switches 621, 622, 623 in lane width setting operation unit 62 after pressing switch 611, the starting output value of electric motor M set in the selected operation mode is retrieved from memory unit 601, and electric motor M is started at this retrieved starting output value. On the other hand, if switches 621, 622, 623 in lane width setting operation unit 62 are not pressed after pressing switch 611, by pressing switch 611, the starting output value of electric motor M set in the selected operation mode is retrieved from memory unit 601, and electric motor M is started at this retrieved starting output value.

[0032] The rotary operation unit 64 inputs values ​​(more specifically, values ​​related to the operation mode) for each of a plurality of operation modes. The rotary operation unit 64 of this embodiment can increase or decrease the starting output value (predetermined set value) and target (desired) output value of the electric motor M. That is, the rotary operation unit 64 can input the starting output value of the electric motor M, as well as the increase and decrease values ​​from the starting output value.

[0033] Specifically, the rotary operation unit 64 has a rotary knob 64A that can be rotated clockwise (to the right) or counterclockwise (to the left), and a rotary encoder (not shown) that detects the rotation angle of the rotary knob 64A (i.e., the direction and amount of rotation). By rotating the rotary knob 64A, the rotary operation unit 64 can input an increase or decrease value corresponding to the rotation angle of the rotary knob 64A (the direction and amount of rotation relative to the position before rotation). Specifically, when the rotary knob 64A is rotated clockwise, the rotary operation unit 64 of this embodiment increases the output value of the electric motor M from the starting output value according to the amount of rotation of the rotary knob 64A (i.e., inputs an increase value from the starting output value), thereby increasing the amount of water discharged from the water-discharging nozzle 5. Furthermore, when the rotary knob 64A is rotated counterclockwise, the rotary operation unit 64 reduces the output value of the electric motor M from the starting output value in accordance with the amount of rotation of the rotary knob 64A (i.e., inputs the amount of reduction from the starting output value), thereby reducing the amount of water discharged from the water-discharging nozzle 5.

[0034] When the Back switch 65 is pressed, the display confirmation window 13 displayed on the display screen 12A of the meter panel 12 is closed. This is described in detail below.

[0035] When a malfunction or error occurs in the sprinkler system 3, the controller 7 displays a display confirmation window 13 for a warning / error occurrence information screen on the display screen 12A of the meter panel 12 (see FIG. 4). When this display confirmation window 13 is displayed on the display screen 12A and the Enter switch 66 on the operation panel 6A is pressed, a warning / error occurrence information screen (not shown) is displayed. On the other hand, when the Back switch 65 on the operation panel 6A is pressed, the display confirmation window 13 closes.

[0036] Furthermore, even if a malfunction or error occurs in the sprinkler device 3, it may be possible to sprinkle water in constant pump rotation mode or manual mode depending on the location of the malfunction and the nature of the error. In such a case, in the control panel 6 of this embodiment, the diodes (e.g., 612A, 613A) of the switches 611, 612, 613 of the selection operation unit 61 that correspond to the operating mode in which water can be sprinkled will flash to notify the operator of the operating mode in which water can be sprinkled.

[0037] Next, sprinkling of water in each operation mode in the sprinkler device 3 configured as above will be described.

[0038] First, the case of sprinkling water in the vehicle speed synchronization mode will be described. When the power is turned on, the display screen 12A of the meter panel 12 displays a predetermined display. Next, when the vehicle speed synchronization switch 611 is pressed, the currently set water sprinkling amount (for example, 0.080 L / m 2 ) is displayed in the water sprinkler amount setting display section 12a of the display screen 12A, and the currently set lane width (e.g., 1 lane) is displayed in the lane width setting display section 12b of the display screen 12A (see FIG. 3). The display screen 12A of this embodiment has a vehicle speed synchronization display section 12c and a vehicle speed display section 12d. The display screen 12A of this embodiment also displays the water level in the tank 4 and the date.

[0039] When the vehicle speed synchronization switch 611 is pressed, the control unit 60 sets the starting output value of the electric motor M stored in the memory unit 601 (for example, the water spray rate of 0.080 L / m 2 The value corresponding to the value of the parameter (value corresponding to the parameter) is retrieved (read) from the storage unit 601.

[0040] Subsequently, when any one of the three switches 621, 622, 623 of the lane width setting operation unit 62 is pressed, the electric motor M is driven at a starting output value to rotate the watering pump P. At this time, the rotary knob 64A of the rotation operation unit 64 is rotated clockwise or counterclockwise to set the target (desired) watering amount, and the electric motor M is driven at an output value corresponding to the set watering amount.

[0041] To stop the water sprinkler system 3, pressing the vehicle speed synchronization switch 611 again after completing the setting will put the water sprinkler system 3 into standby mode and stop the water sprinkler pump P. Furthermore, if the water sprinkler vehicle 1 is performing water sprinkler work while traveling after completing the setting, the controller 7 controls the drive of the electric motor M to adjust the rotation speed of the water sprinkler pump P so that the amount of water sprinkled corresponding to the vehicle speed detected by the vehicle speed sensor S1, i.e., the volume of water sprinkled per unit area of ​​the road surface, is constant. The output value of the electric motor M corresponding to the set amount of water sprinkled is stored in the memory unit 601. Therefore, for subsequent water sprinkler work, simply pressing the vehicle speed synchronization switch 611 will drive the electric motor M at the target output value to rotate the water sprinkler pump P, thereby enabling the water sprinkler system to perform the same amount of water sprinkled as the first time.

[0042] When the watering operation is completed, the power to the operation panel 6A is turned off. In this way, when the power to the operation panel 6A is turned off, the power to the operation panel 6A is turned on for the next watering operation, and when the vehicle speed synchronization switch 611 is pressed (i.e., the vehicle speed synchronization mode is selected), the electric motor M is driven at the starting output value stored in the memory unit 601 to rotate the watering pump P. The starting output value of the electric motor M may be set to 0. In this case, the amount of water sprayed when the electric motor M starts will also be 0.

[0043] Next, a case where watering is performed in constant pump rotation mode will be described. When the power is turned on, the display screen 12A of the meter panel 12 displays a predetermined message. Next, when the constant pump rotation switch 612 is pressed, the control unit 60 retrieves (reads) the starting output value of the electric motor M stored in the memory unit 601 from the memory unit 601, and drives the electric motor M at the starting output value to rotate the watering pump P. Next, the rotary knob 64A of the rotary operation unit 64 is rotated to set the electric motor M to the target (desired) rotation speed (i.e., the target (desired) amount of water to be sprayed), and the electric motor M is driven at the output value corresponding to this set rotation speed.

[0044] Furthermore, when the starting output value of the electric motor M is set to 0, the watering pump P does not rotate immediately, but begins to rotate when the starting output value of the electric motor M is set from 0 to the target rotation speed (output value) using the rotary knob 64A.

[0045] After setting the rotation speed (output value) of the electric motor M, the sprinkler truck 1 performs watering work while traveling. While the sprinkler truck 1 is traveling, the electric motor M is driven at the target rotation speed (output value) to rotate the sprinkler pump P. If the pump constant rotation switch 612 is pressed again after setting the target rotation speed (output value) of the electric motor M, the sprinkler device 3 enters standby mode and the sprinkler pump P stops.

[0046] Next, a description will be given of the case where water is sprinkled in the manual operation mode. When the power is turned on, the display screen 12A of the meter panel 12 displays a predetermined message. Next, when the manual switch 613 is pressed, the control unit 60 retrieves (reads) the starting output value of the electric motor M stored in the memory unit 601, and drives the electric motor M at the starting output value to rotate the watering pump P. Next, the rotary knob 64A of the rotary operation unit 64 is rotated to set the electric motor M to a target (desired) rotation speed, and the electric motor M is driven at an output value corresponding to this set rotation speed.

[0047] Furthermore, when the starting output value of the electric motor M is set to 0, the watering pump P does not rotate immediately, but begins to rotate when the starting output value of the electric motor M is set from 0 to the target rotation speed (output value) using the rotary knob 64A.

[0048] After setting the rotation speed (output value) of the electric motor M, the sprinkler truck 1 performs watering work while traveling. While the sprinkler truck 1 is traveling, the electric motor M is driven at the target rotation speed (output value) to rotate the sprinkler pump P. If the manual switch 613 is pressed again after setting the target rotation speed (output value) of the electric motor M, the sprinkler device 3 enters standby mode and the sprinkler pump P stops.

[0049] According to the above-described sprinkler vehicle 1, the rotary operation unit (input unit) 64 can adjust (input) values ​​related to the operation mode (rotation speed, output value, etc.) in each of the multiple operation modes. In this way, by using a common rotary operation unit (input unit) 64 (i.e., one) that adjusts (inputs) the values ​​in each operation mode, the number of parts can be reduced compared to a configuration in which a rotary operation unit (input unit) 64 is provided for each operation mode, i.e., a configuration having multiple rotary operation units (input units) 64.

[0050] Furthermore, in the water truck 1 of this embodiment, the rotary operation unit 64 has a rotary knob 64A and a rotary encoder that detects the rotation angle of the rotary knob 64A, and the value related to the operation mode input to the control unit 60 is at least one of an increase value and a decrease value according to the rotation angle of the rotary knob 64A. By using a rotary encoder for the rotary operation unit 64 in this way, at least one of an increase value and a decrease value can be input simply by rotating the rotary knob 64A clockwise or counterclockwise, without having to return the rotary knob 64A of the rotary operation unit 64 to its initial position after each operation.

[0051] The specially equipped vehicle of 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. For example, the configuration of one embodiment can be added to the configuration of another embodiment, or part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, part of the configuration of one embodiment can be deleted.

[0052] The specially equipped vehicle in the above embodiment is a sprinkler truck, but is not limited to this configuration. The specially equipped vehicle may be a tank truck capable of carrying liquids such as gasoline, diesel, or kerosene, a dump truck, a garbage truck, a concrete pump truck, aerial work vehicle, a vehicle transporter, a powder transporter, a tailgate lifter, or the like. In other words, the specially equipped vehicle may be any vehicle having a chassis on which mounted equipment that operates using power from a power source is mounted.

[0053] Furthermore, in the specially equipped vehicle 1 of the above embodiment, the power source that drives (operates) the mounted equipment is the power source for driving the mounted equipment (in the above embodiment, the electric motor M), but this configuration is not limited to this. The specially equipped vehicle (water truck) 1 may be configured so that the drive source for traveling (engine E / G) is also used to drive the mounted equipment (water pump P, etc.). In this case, for example, the idling speed of the engine E / G in the water truck 1 is set to the starting speed of the water pump P in each operating mode.

[0054] Furthermore, in the specially equipped vehicle 1 of the above embodiment, the switches 611, 612, 613 of the selection operation unit 61 also serve as a start operation unit for starting the electric motor M, but this configuration is not limited to this. In the specially equipped vehicle (water truck) 1, the start operation unit for starting the power source (for example, the electric motor M) of the mounted object and the selection operation unit 61 (switches 611, 612, 613) for selecting (switching) the operating mode of the mounted object may be arranged independently.

[0055] Furthermore, although the control unit 60 of the specially equipped vehicle 1 in the above embodiment has three operation modes, the configuration is not limited to this. The control unit 60 may be configured to have two or four or more operation modes.

[0056] Furthermore, the specific configuration (setting) of the operation mode is not limited. For example, the parameters may be different for each operation mode, or the parameters may be the same for each operation mode but the mounted object may perform different operations.

[0057] Furthermore, although the specially equipped vehicle 1 in the above embodiment is configured to select three operation modes using the corresponding three switches 611, 612, 613, the configuration is not limited to this. The specially equipped vehicle 1 may be configured to allow selection of three operation modes using one operation unit (switch, input unit, etc.). Furthermore, the specially equipped vehicle 1 may be configured such that the selection operation unit 61 is made up of two switches, such as a + switch and a - switch, and that pressing the switch switches from a predetermined operation mode to the operation mode adjacent to the + side or the - side of the predetermined operation mode among a plurality of operation modes arranged in sequence.

[0058] In the specially equipped vehicle 1 of the above embodiment, the switches 611, 612, 613 of the selection operation unit 61 and the screen display switching operation unit 63 are configured as push buttons, but are not limited to this configuration. The selection operation unit 61 and the screen display switching operation unit 63 may be configured to input by a rotation operation, a slide operation, a lever operation, or the like.

[0059] Furthermore, in the rotary operation unit 64 of the specially equipped vehicle 1 in the above embodiment, a value (increase value or decrease value) corresponding to the rotation angle of the rotary knob 64A is input, but this configuration is not limited to this. The rotary operation unit 64 may be configured to input a value (increase value or decrease value) corresponding to the speed or acceleration in the rotation direction of the rotary knob 64A. For example, the greater the speed or acceleration in the rotation direction of the rotary knob 64A, the greater the input value (increase value or decrease value).

[0060] In the specially equipped vehicle 1 of the above embodiment, the rotary operation unit (input unit for inputting values ​​related to the operation mode) 64 is configured to rotate the rotary knob 64A, but is not limited to this configuration. The input unit may be configured to input values ​​related to the operation mode (for example, at least one of an increase value and a decrease value) by operating a push button, a slide operation, a lever operation, or the like.

[0061] In the specially equipped vehicle 1 of the above embodiment, the rotary operation unit 64 may be configured with a variable resistance volume. In this case, a value based on a change in resistance value according to the rotation angle of the rotary knob 54A is input to the rotary operation unit 64.

[0062] In the specially equipped vehicle 1 of the above embodiment, the parameter for which at least one of an increase value and a decrease value is input by the rotary operation unit (input unit) 64 is the rotation speed of the electric motor M, but this is not limited to this configuration. The parameter may be the amount of water sprayed per unit area on the road surface (l / m 2 ) or the rotation speed (rpm) of the watering pump P. In other words, the parameters may be any parameters that correspond to the operation of the equipment mounted on the specially equipped vehicle 1 or the type of power source for operating the equipment, such as speed (m / s), rotation speed (rpm), discharge flow rate (l / min), discharge amount per unit rotation (cc / rev), pressure (MPa), etc.

[0063] Furthermore, in the specially equipped vehicle 1 of the above embodiment, the amount of water sprayed is adjusted by controlling the rotation speed of the electric motor M, but this is not a limitation. The amount of water sprayed may also be adjusted by a proportional valve (a valve that can change the amount of fluid passing through in response to a signal).

[0064] Furthermore, in the specially equipped vehicle 1 of the above embodiment, the orientation of the water-discharging nozzle 5 is fixed. However, for example, the sprinkler system 3 may be configured to include, as mounted components, a hydraulic actuator for changing the spray direction of the water-discharging nozzle 5 and a hydraulic pump for operating the hydraulic actuator, thereby enabling the orientation of the water-discharging nozzle 5 to be changed during water spraying or while the vehicle is stopped. The power source for driving the hydraulic pump may be the electric motor M that drives the water-sprinkler pump P, or an electric motor provided for the hydraulic pump. In a configuration including such a hydraulic actuator and hydraulic pump, the value input by the rotary operation unit (input unit) 64 may be at least one of an increase and decrease in the magnitude of the power output from the power source (such as an electric motor) and the discharge rate of the hydraulic pump. This allows the orientation of the water-discharging nozzle 5 to be changed during water spraying in a predetermined operating mode. The hydraulic actuator and hydraulic pump are not limited to those of the sprinkler system 3, and may be components of other mounted components.

[0065] Furthermore, in the specially equipped vehicle 1, the values ​​input by the rotation operation unit 64 may be values ​​relating to the operating angle, length, direction, speed, etc. of the mounted object (for example, a water-discharge nozzle).

[0066] In addition, in the specially equipped vehicle 1 of the above embodiment, the control unit 60 and the input unit (in the example of the above embodiment, the rotary operation unit) 64 are included in the configuration of the mounted object (sprinkler device) 3, but this configuration is not limiting. In the specially equipped vehicle 1, the control unit 60 and the input unit 64 do not have to be included in the configuration of the mounted object 3.

[0067] Furthermore, in the specially equipped vehicle 1 of the above embodiment, the input unit 64 inputs a value for the initial value of one parameter in each operation mode (in the example of the above embodiment, an increase or decrease value for the initial value of the electric motor M), but this configuration is not limited to this. The input unit 64 may also be configured to input values ​​(increase or decrease values) for each initial value of multiple parameters in one operation mode. [Explanation of symbols]
