DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example of the present invention, and is not intended to limit the technical scope of the present invention.

[0010] (Embodiment 1) [1] Overview First, an overview of a work machine 10 according to this embodiment will be described with reference to Figs. 1 to 4.

[0011] The work machine 10 includes a machine body 11. The machine body 11 is configured to be able to mount a work implement 12. The machine body 11 has an automatic steering function.

[0012] In this embodiment, the work machine 10 is equipped with a control device 2 (see FIG. 2). The control device 2, together with a terminal device 3 (see FIG. 2), constitutes a control system 1 that controls the work machine 10. The work machine 10 and the terminal device 3 are capable of communicating with each other. In this disclosure, "capable of communication" means that information can be exchanged directly or indirectly via a communication network or a repeater, etc., by an appropriate communication method such as wired communication or wireless communication (communication using radio waves or light as a medium). Examples of communication networks include the Internet, a local area network (LAN), a wide area network (WAN), a public telephone line, a mobile phone line network, a packet line network, or a wireless LAN. It is not an essential component of the control system 1 that the work machine 10 and the terminal device 3 are capable of communicating with each other.

[0013] In this embodiment, as an example, the terminal device 3 is configured as a general-purpose terminal such as a tablet terminal, a smartphone, a laptop computer, etc. Dedicated application software (program) is installed in the terminal device 3 configured as a general-purpose terminal, and the terminal device 3 functions as the terminal device 3 of the control system 1 by starting up the application software.

[0014] The work machine 10 moves through a target area F1 (see FIG. 1 ) and performs some work within the target area F1 using the work implement 12. In this disclosure, "work" refers to a job performed by the work implement 12 in the target area F1, and includes various types of work, such as plowing, leveling, sowing, fertilizing, spraying pesticides, planting (rice planting) or harvesting, and construction work. In this embodiment, as an example, the work performed by the work machine 10 is plowing.

[0015] The work implement 12 performs work within the target area F1 when the body 11 of the work machine 10 moves through the target area F1. In this embodiment, as an example, the work implement 12 is a tiller such as a rotary tiller or a plow that performs tilling work.

[0016] This type of working implement 12 includes a directly mounted working implement that is directly attached to a three-point link, and a towed working implement that is towed by the body 11. In this embodiment, as an example, the working implement 12 is a directly mounted rotary tiller that is removably attached to the body 11 of the work machine 10. Here, the working implement 12 is attached to the rear side of the body 11 (the side opposite to the forward movement direction of the body 11). In other words, the (directly mounted) working implement 12 is connected to the rear side of the body 11, and performs work while moving forward together with the body 11 when the body 11 moves forward. In this embodiment, the working implement 12 is included as a component of the work machine 10, but since the working implement 12 is detachable from the body 11, it does not have to be included as a component of the work machine 10.

[0017] The term "working machine" in this disclosure means a vehicle that performs various tasks in a target area F1 such as a farm field, and examples of such tasks include agricultural machines (farm machinery) such as tractors, seeding machines, rice transplanters, spreaders, sprayers, transplanters, and harvesters. The working machine 10 may be, for example, a construction machine (construction machinery). In this embodiment, unless otherwise specified, a case will be described in which the working machine 10 is a tractor equipped with a rotary tiller as the working machine 12. That is, the working machine 10 is configured by connecting a (direct-mounted) rotary tiller as the working machine 12 to a tractor as the machine body 11. In this working machine 10, the machine body 11 travels through the target area F1 such as a farm field, thereby enabling tilling work in the target area F1.

[0018] Thus, in this embodiment, the machine body 11 is a type of vehicle that moves by traveling in the target area F1. Here, as shown in Fig. 1 and Fig. 4, the machine body 11 has steering wheels 111 consisting of a pair of left and right front wheels, and driving wheels 112 consisting of a pair of left and right rear wheels, and travels in the target area F1 with these four wheels (the pair of steering wheels 111 and the pair of driving wheels 112). In Fig. 4 to Fig. 6, illustration of axles and the like is omitted.

[0019] Also, in this embodiment, as an example, the work machine 10 is an automatic machine that can operate by automatic traveling (autonomous traveling, etc.) while allowing a driver (operator) to ride on it. However, the work machine 10 is not limited to this, and may be an unmanned machine that operates automatically, or may be operated by operation (including remote operation) of a driver (operator).

[0020] The "target area" in the present disclosure is an area in which the work machine 10 moves and performs various tasks such as plowing, leveling, sowing, fertilizing, spraying pesticides, planting (rice planting), or harvesting, and includes paddy fields, fields, orchards, pastures, and the like. For example, if a paddy field or field in which crops (agricultural products) such as rice, wheat, soybeans, or buckwheat are grown is the target area F1, the crops grown in the target area F1 are agricultural products. Furthermore, if plants are grown in a plantation field, the plantation field is the target area F1, and if trees that become lumber are grown in a forest as in forestry, the forest is the target area F1. In this case, the crops grown in the target area F1 are plants or trees, etc. In this embodiment, unless otherwise specified, the work machine 10 is used for plowing a field (target area F1), and a case will be described in which the target area F1 is a paddy field for growing rice. Furthermore, the target area F1 is not limited to a farm field. For example, if the work machine 10 is a construction machine, the site where the construction machine performs work becomes the target area F1.

[0021] Furthermore, the work machine 10 can move by automatic travel not only in the target area F1 (field in this case), but also on roads such as out-of-field routes outside the target area F1. The work machine 10 is configured to be able to automatically travel (move) along target routes (including out-of-field routes) set in advance within and outside the target area F1, based on position information of the current position of the work machine 10 measured by the positioning device 15. The out-of-field routes are, for example, inter-field connecting roads that connect a plurality of target areas F1 (fields). The inter-field connecting roads are farm roads, forest roads, public roads, private roads, motorways, etc., and may be roads dedicated to the work machine 10, or may be roads on which general vehicles (passenger cars, etc.) can pass.

[0022] Furthermore, "automatic driving" in this disclosure includes "autonomous driving" in which the work machine 10 drives autonomously without the operation of an operator, and "semi-automatic driving" in which only steering is automated, such as straight-line assist.

[0023] "Autonomous driving" is a driving mode in which, for example, in addition to automatic steering of the steering wheel 111, control of the vehicle speed and the like is also performed automatically so that the work machine 10 travels along a target route. "Straight-line assist" is a driving mode in which only automatic steering of the steering wheel 111 is performed so that the work machine 10 travels along a straight route parallel to a reference straight line (reference line), and the vehicle speed and the like are controlled by the operation of the operator. In other words, in "semi-automatic driving", although the work machine 10 cannot travel without the operation of the operator, the burden of steering is reduced for the operator and the work machine can travel along a target route such as a straight route, leading to improved work efficiency. In both autonomous driving and semi-automatic driving, the steering wheel 111 is automatically steered, so it can be said to be one mode of "automatic steering mode".

[0024] In the automatic steering mode, the steering wheels 111 are automatically steered by an automatic steering mechanism including a steering motor. That is, instead of an operator operating the steering operation unit 41 (see FIG. 1), automatic steering is realized by changing the direction of the steering wheels 111 by the output of the steering motor. In short, the machine body 11 of the work machine 10 according to this embodiment has an automatic steering function that automatically steers the steering wheels 111.

[0025] [2] Work machine configuration Next, the configuration of the work machine 10 according to this embodiment will be described in detail with reference to Figs.

[0026] In this embodiment, for ease of explanation, the vertical direction when the work machine 10 is in a usable state is defined as the up-down direction D1 (see FIG. 1). The front-rear direction D2 and the left-right direction D3 (see FIG. 4) are defined based on the direction as seen by the driver (operator) riding on the body 11 (of the driving section 5) of the work machine 10. The left side of the left-right direction D3 refers to the left side when the body 11 is traveling forward (advancing), and the right side of the left-right direction D3 refers to the right side when the body 11 is traveling forward (advancing). However, these directions are not intended to limit the direction of use of the work machine 10 (direction during use).

[0027] 2, in addition to a machine body 11 and a work implement 12, a control device 2, a traveling device 13, a steering device 14, a positioning device 15, a detection device 16, a communication device 17, a power source 18, and a display operation device 6. The control device 2, the traveling device 13, the steering device 14, the positioning device 15, the detection device 16, the communication device 17, the power source 18, and the display operation device 6 are all mounted on the machine body 11.

[0028] The machine body 11 has a driving section 5 (see FIG. 1) on which a driver (operator) can ride. A steering operation section 41, an operation lever 42, a pedal 43, etc., which are included in the steering device 14, are arranged in the driving section 5. The steering operation section 41, the operation lever 42, the pedal 43, etc. are operation sections that are operated by the operator. Therefore, the work machine 10 is configured to be capable of not only automatic driving, but also manual driving by manual operation by the operator.

[0029] A work machine coupling section 46 formed of a three-point linkage mechanism or the like is provided at the rear of the machine body 11. A work machine 12 can be attached to the work machine coupling section 46. Power generated by the power source 18 can be transmitted to the towed work machine 12 via a transmission 44 and a power take-off shaft (PTO shaft) disposed at the rear of the machine body 11. Here, since the work machine 12 is detachably coupled to the work machine coupling section 46, it is also possible to couple a device other than the work machine 12 to the machine body 11.

[0030] In this embodiment, the work implement 12 is a directly mounted rotary tiller, and thus can perform tilling work on a field as the target area F1 when the machine body 11 moves forward. The work implement 12 is variable in its position (relative height) in the up-down direction D1 relative to the machine body 11. This makes it possible to vary the height of the work implement 12 when the field scene, which is the ground surface of the target area F1, is used as a reference, and for example, by raising the work implement 12 to a height that is away from the ground surface of the target area F1, the work machine 10 can travel in a non-working state where the work implement 12 is not performing work.

[0031] As shown in Fig. 1, the traveling device 13 is a device that drives drive wheels 112 consisting of (a pair of left and right) rear wheels to make the work machine 10 travel. The traveling device 13 includes a transmission 44, and transmits power generated by the power source 18 to the drive wheels 112 via the transmission 44 to make the machine body 11 travel forward or backward. Furthermore, the traveling device 13 includes a brake device, and is also capable of decelerating or stopping the machine body 11. In this embodiment, the drive wheels 112 are normal wheels, but are not limited thereto, and for example, the machine body 11 may be a half-crawler type machine body 11 that employs crawlers (tracks) for the drive wheels 112.

[0032] As shown in Fig. 1, the steering device 14 is a device that steers the steering wheels 111 consisting of (a pair of left and right) front wheels. The steering device 14 includes a steering operation unit 41, and steers the steering wheels 111 in response to an operator's operation of the steering operation unit 41. As shown in Fig. 4, the pair of steering wheels 111 have a reference position in which they face the front-rear direction D2 in a plan view, that is, a position in which the rotation axis is along the left-right direction D3, and are steered by the steering device 14 so as to tilt leftward or rightward from the reference position. In other words, the steering device 14 steers the pair of steering wheels 111 by changing the orientation of the pair of steering wheels 111.

[0033] When the steering operation unit 41 is operated clockwise from a state in which the pair of steering wheels 111 are in a reference posture, the steering device 14 steers the pair of steering wheels 111 (front ends) to tilt to the right, and turns the vehicle 11 to the right when the vehicle 11 moves forward. On the other hand, when the steering operation unit 41 is operated counterclockwise from a state in which the pair of steering wheels 111 are in a reference posture, the steering device 14 steers the pair of steering wheels 111 (front ends) to tilt to the left, and turns the vehicle 11 to the left when the vehicle 11 moves forward. In this embodiment, it is the steering operation unit 41 that the operator operates during manual steering, but this is not limited thereto, and manual steering may be performed by the operator operating an operation lever or the like, for example.

[0034] The traveling device 13 and the steering device 14 enable the vehicle 11 to travel within the target area F1 in the forward / backward direction D2 and the left / right direction D3. For example, when the driving wheels 112 are driven by the traveling device 13 to move the vehicle 11 forward, if the angle of the steering wheels 111 is changed by the steering device 14, the vehicle 11 turns in the left / right direction D3, changing the traveling direction of the vehicle 11.

[0035] The positioning device 15 determines the current position (latitude, longitude, altitude, etc.) of the aircraft 11. Specifically, the positioning device 15 is disposed on, for example, the ROPS frame 114, and calculates the current position (latitude and longitude) of the aircraft 11 using a satellite positioning system such as the Global Navigation Satellite System (GNSS). That is, the positioning device 15 has a positioning antenna that receives positioning signals from multiple satellites 202 (see FIG. 3), and calculates the current position based on the positioning signals. Furthermore, the positioning device 15 includes an inertial sensor, and can also detect the attitude, such as the current heading, of the aircraft 11.

[0036] Furthermore, the positioning device 15 employs a relatively high-precision positioning method such as RTK (Real Time Kinematic) positioning, which calculates the current position of the work machine 10 by utilizing correction information corresponding to a base station 201 (reference station) close to the work machine 10. The current position of the machine body 11 may be the same position as the positioning position (position of the positioning antenna), or may be a position displaced from the positioning position, such as the center position of the machine body 11 in a planar view. The positioning device 15 may be substituted with, for example, a mobile phone terminal, a smartphone, a tablet terminal, or a quantum compass.

[0037] The detection device 16 detects obstacles in the detection area. The detection device 16 includes an obstacle sensor and a detection processing unit. The obstacle sensor may include various sensors such as a camera (image sensor), a sonar sensor, a human sensor, a radar, or a LiDAR (Light Detection and Ranging). The obstacle sensor may be a three-dimensional sensor that measures the distance to an object (obstacle) by a Time Of Flight (TOF) method that measures the distance to a ranging point based on the round-trip time it takes for light or sound to reach the ranging point and return. The detection processing unit detects an obstacle based on measurement information acquired from the obstacle sensor. Here, the detection processing unit may detect only the presence or absence of an obstacle, or may detect the position, shape, number, or attributes (including type, etc.) of the obstacle.

[0038] The detection results of the detection device 16 are output to the control device 2. When the detection device 16 detects an obstacle at least during the automatic traveling of the work machine 10, the control device 2 outputs an alarm (including an alarm by sound and / or light) and executes obstacle avoidance processing (including detouring, decelerating, stopping, etc.) by controlling the traveling device 13 and the steering device 14. Furthermore, the control device 2 may output obstacle position information and the execution history of the avoidance processing to the terminal device 3 and cause the terminal device 3 to display, etc.

[0039] The communication device 17 is a communication interface for connecting the work machine 10 (the control device 2 and the positioning device 15, etc.) to an external device via a wired or wireless connection and for executing data communication with the external device in accordance with a predetermined communication protocol. In this embodiment, the communication device 17 is capable of mutual communication with at least the terminal device 3, which is an external device. For example, a mobile phone terminal, a smartphone, a tablet terminal, etc. may be used as the communication device 17.

[0040] The power source 18 is a drive source that supplies power to at least the traveling device 13. The power source 18 is disposed at the front of the machine body 11 and is covered by a bonnet 45. The power source 18 is a drive source for the work machine 10, and is a diesel engine, for example. However, the power source 18 of the work machine 10 is not limited to a diesel engine, and may be an engine such as a gasoline engine, an electric motor, a hybrid system of an engine and an electric motor, or the like.

[0041] Furthermore, the power source 18 drives a hydraulic pump to supply hydraulic oil from the hydraulic pump to a hydraulic cylinder or the like of a power steering mechanism of the steering device 14. In other words, the power source 18 is configured to be able to supply power to the power steering mechanism as well.

[0042] The transmission 44 is disposed behind the power source 18 and below the driving section 5. The transmission 44 includes a power transmission device. The rotational power of the power source 18 is transmitted to at least one of the steering wheels 111 and the driving wheels 112 (the driving wheels 112 in this embodiment) via the power transmission device in the transmission 44.

[0043] The driver's section 5 is disposed behind the power source 18 in the vehicle body 11. The driver's section 5 has a driver's seat 51 (see FIG. 4) and a dashboard 52. The driver's seat 51 is where the driver sits. The dashboard 52 also serves as a steering column, and is disposed in front of the driver's seat 51. The driver's seat 51 is not shown in any figures other than FIG. 4.

[0044] As an example, the steering operation unit 41 is a steering wheel operated by a driver sitting in the driver's seat 51. The steering operation unit 41 is rotatably supported by a steering shaft arranged in the dashboard 52. The steering operation unit 41 is arranged in front of the driver's seat 51 and above the dashboard 52. The vehicle 11 can change the direction (steering angle) of the steering wheels 111 by rotating the steering operation unit 41.

[0045] Additionally, the driving section 5 is provided with, for example, an operating lever 42 and pedals 43 operated by the driver, a meter indicating the speed of the work machine 10, and the like. The operating levers 42 may include multiple types of levers, for example, a main speed change lever, a sub speed change lever, or a working lever. The pedals 43 may include multiple types of pedals, for example, an accelerator pedal, a brake pedal, and the like.

[0046] In this embodiment, the work machine 10 is equipped with a ROPS frame 114 behind the driver's seat 51. The ROPS frame 114 protects the driver in the event of a rollover of the work machine 10. The work machine 10 is not limited to a ROPS specification equipped with the ROPS frame 114, and may also be a cabin type in which the driver's seat 51 is covered with a cabin.

[0047] 5 and 6, the driver's section 5 is provided with mudguards 53. Specifically, a pair of left and right mudguards 53 are disposed at the front end of the driver's section 5. The mudguards 53 are plate-shaped members having a thickness in the front-rear direction D2. The mudguards 53 are mudguards, and are made of, for example, a light-transmitting acrylic plate or other member so as not to obstruct forward visibility.

[0048] Furthermore, the driver's section 5 is provided with a mudguard frame 54 that supports the mudguard 53. Specifically, a pair of left and right mudguard frames 54 are disposed at the front end of the driver's section 5 corresponding to the pair of left and right mudguards 53. The pair of mudguard frames 54 are disposed symmetrically with respect to the dashboard 52. Each mudguard frame 54 extends upward from its lower end, and its upper end has a curved shape that curves inward (toward the dashboard 52) in the left-right direction D3. One end on the lower end side of each mudguard frame 54 is fixed to the floor 55 of the driver's section 5, and the other end is fixed to the dashboard 52, more precisely, to a dashboard frame 57 (see FIG. 7).

[0049] The display operation device 6 is a device that displays various information to the driver and accepts operations by the driver. For example, the display operation device 6 can accept a switching operation between an automatic steering mode in which the steering wheel 111 is automatically steered and a manual steering mode in which the steering wheel 111 is manually steered. The display operation device 6 outputs a signal corresponding to the accepted operation to the control device 2.

[0050] The control device 2 mainly comprises a computer system having one or more processors such as a CPU (Central Processing Unit) and one or more memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and executes various processes (information processing). In this embodiment, the control device 2 mainly comprises a computer system having one or more processors, and the control device 2 is realized by the one or more processors executing a work machine control program. In this embodiment, the control device 2 is an integrated controller that controls the entire work machine 10, and is composed of, for example, an electronic control unit (ECU). However, the control device 2 may be provided separately from the integrated controller.

[0051] The control device 2 is configured to be able to communicate with devices provided in each part of the machine body 11. That is, the control device 2 is electrically connected to the working machine 12, the traveling device 13, the steering device 14, the positioning device 15, the detection device 16, the communication device 17, the power source 18, the display operation device 6, and the like. This allows the control device 2 to control the working machine 12, the traveling device 13, the steering device 14, the display operation device 6, and the like, and to obtain the outputs of the positioning device 15, the detection device 16, the display operation device 6, and the like. Here, the control device 2 may directly exchange various types of information (data) with each device, or indirectly via a repeater or the like.

[0052] In this embodiment, the control device 2 includes a traveling control unit 21, a steering control unit 22, an operation control unit 23, and a storage unit 24, as shown in FIG.

[0053] The traveling control unit 21 controls the traveling device 13 and the power source 18. At least during autonomous traveling, the traveling control unit 21 controls the traveling device 13 and the power source 18 in place of the operator so as to bring the vehicle speed, engine speed, and the like closer to target values. The traveling control unit 21 can also control the brake device of the traveling device 13 to decelerate or stop the vehicle 11.

[0054] The steering control unit 22 controls the steering device 14. The steering control unit 22 has an automatic steering mode and a manual steering mode as operation modes, and is configured to be able to switch between the automatic steering mode and the manual steering mode. The manual steering mode is a mode in which the operator performs steering by operating the steering operation unit 41. The steering control unit 22 operates in the automatic steering mode at least during autonomous driving or semi-automatic driving, and controls the steering device 14, instead of the operator, so as to bring the steering angle of the steered wheels 111 closer to the target steering angle.

[0055] In particular, during autonomous driving, the steering control unit 22, together with the driving control unit 21, controls the work machine 10 based on the current position of the machine body 11 so that the machine body 11 drives along the target route. The target route for autonomously driving the work machine 10 is generated, for example, in the terminal device 3. That is, the work machine 10 acquires route data corresponding to the target route from the terminal device 3, and drives autonomously according to the target route.

[0056] The work control unit 23 controls the work implement 12. At least during autonomous driving, the driving control unit 21 executes control of the work implement 12 based on the current position of the machine body 11 on the target route. Specifically, if the work machine 10 is traveling on a work route among the target routes where work is to be performed by the work implement 12, the work control unit 23 sets the work implement 12 to a work position and performs work by the work implement 12. On the other hand, if the work machine 10 is traveling on a non-work route among the target routes where work is not to be performed by the work implement 12, the work control unit 23 raises the work implement 12 to a non-work position and stops work by the work implement 12.

[0057] The storage unit 24 is a non-volatile memory or the like that stores various data such as a work machine control program and target route information related to the target route. In other words, the traveling control unit 21 and the steering control unit 22 can, for example, cause the vehicle to autonomously travel along the target route based on the target route information stored in the storage unit 24.

[0058] In addition to the configuration described above, the work machine 10 is further equipped with a battery, a fuel tank, various sensors, etc. The battery supplies power for operation to each part of the work machine 10, such as the control device 2. In particular, electronic devices such as the control device 2, steering device 14, positioning device 15, detection device 16, and communication device 17 operate using power supplied from the battery, and can therefore operate even when the power source 18 is stopped.

[0059] Here, an overview of the automatic traveling (automatic steering traveling) executed by the work machine 10 according to this embodiment will be described. When performing automatic traveling, first, a reference line is set.

[0060] When setting the reference line, first, the work machine 10 is moved to an appropriate position (point A) within the target area F1, and point A is registered. Point A is registered in response to a registration command from the driver. The position of the machine body 11 obtained by the positioning device 15 at the time the command to register point A is issued is registered as the position of point A.

[0061] Once point A has been registered, the driver manually drives the work machine 10 (straight ahead) to move it to a predetermined position (point B). Then, when the work machine 10 reaches the predetermined position, point B is registered. Point B is registered in response to a registration command from the driver. The position of the machine body 11 obtained by the positioning device 15 at the time the command to register point B is issued is registered as the position of point B.

[0062] Once points A and B are registered, a straight line passing through points A and B is set as a reference line.

[0063] When the reference line is set, lines parallel to the reference line are generated at a predetermined interval as a target route (straight route). During automatic driving (automatic driving), steering control of the work machine 10 is performed so that the position of the machine body 11 acquired by the positioning device 15 coincides with the target route.

[0064] The method of setting the reference line is not limited to the above method. For example, instead of registering point B, the reference line may be automatically registered according to the orientation of the aircraft 11 at the time point A is registered. Also, instead of registering point B, when point A is registered, the reference line may be automatically registered according to the azimuth angle set (for example, by the driver).

[0065] [3] Configuration of display and operation device The work machine 10 is equipped with a display operation device 6, as shown in FIGS.

[0066] The display operation device 6 is disposed on one side as viewed from the center of the left-right direction D3 of the driving unit 5. In this embodiment, as an example, the display operation device 6 is disposed on the right side as viewed from the center of the driving unit 5 in the left-right direction D3.

[0067] Specifically, the display operation device 6 is disposed to the right of the steering operation unit 41. Furthermore, at least a part of the display operation device 6 is disposed alongside the steering operation unit 41 in the left-right direction D3. In other words, at least a part of the display operation device 6 is disposed at the same height as the steering operation unit 41, that is, at the same position as the steering operation unit 41 in the up-down direction D1.

[0068] Such an arrangement makes it easy to prevent the steering operation unit 41 from blocking the driver's view of the display operation device 6 or from interfering with the operation of the display operation device 6. This makes it easy to improve the visibility and operability of the display operation device 6. In addition, it is easy to ensure the field of view in front of the driver's seat 51.

[0069] Furthermore, since at least a portion of the display operation device 6 is at the same height as the steering operation unit 41, it is easy for the driver operating the steering operation unit 41 to operate the display operation device 6 and also easy for the driver to see the display operation device 6.

[0070] In addition, at least a part of the display operation device 6 is located forward of the rear end of the steering operation unit 41. This makes it difficult for the display operation device 6 to interfere with the driver sitting in the driver's seat 51 in driving the work machine 10, such as operating the steering operation unit 41. Particularly in this embodiment, the entire display operation device 6 (display unit 61 and operation unit 62) is located forward of the rear end of the steering operation unit 41.

[0071] Furthermore, in this embodiment, an operation lever 42 is disposed to the side of the driver's seat 51. As an example, the operation lever 42 is a main shift lever that adjusts the speed (vehicle speed) of the work machine 10. The display operation device 6 is located in front of the operation lever 42. At least a part of the display operation device 6 is disposed at the same height as the operation lever 42, that is, at the same position as the operation lever 42 in the up-down direction D1. This makes it easier for the driver to access the display operation device 6 while gripping the operation lever 42, making it easier to improve the operability of the display operation device 6.

[0072] 7 to 10, the display operation device 6 includes a display unit 61 and an operation unit 62. In Fig. 7 to Fig. 10, only the display operation device 6 and its peripheral members are shown, and other members are omitted from the illustration.

[0073] The display unit 61 displays at least information related to the automatic steering function of the work machine 10. The display unit 61 is a user interface for presenting information to a driver (operator), such as, for example, a liquid crystal display or an organic EL display that displays various information. In this embodiment, as an example, the display unit 61 has a substantially rectangular parallelepiped shape and a horizontally long rectangular display screen. However, the shape of the display unit 61 (and its display screen) is not limited to this example, and may be, for example, a vertically long display screen, etc.

[0074] The operation unit 62 includes a first operation member 621 and a second operation member 622 as operation members for performing operations related to at least the automatic steering function of the work machine 10. The first operation member 621 is, for example, a push button switch, and enables the automatic driving function to be switched on and off. The second operation member 622 is, for example, a seesaw switch, and enables correction of the automatic driving route (offset correction). The surface (back surface) of the operation unit 62 facing the driver sitting in the driver's seat 51 has a substantially rectangular shape having a length in the left-right direction D3.

[0075] As an example, when the second operating member 622 is operated to the right, the position of the target route displayed on the display unit 61 can be shifted to the right, and when the second operating member 622 is operated to the left, the position of the target route displayed on the display unit 61 can be shifted to the left. This allows the driver to intuitively operate the second operating member 622 to correct the route.

[0076] Here, the first operation member 621 is preferably disposed closer to the steering operation unit 41 than the second operation member 622. In particular, since the display operation device 6 is disposed to the right of the steering operation unit 41, the first operation member 621 is preferably disposed to the left of the second operation member 622.

[0077] Since the first operating member 621, which switches the automatic driving function on and off, is located closer to the driver (compared to the second operating member 622), it is easy for the driver to switch the automatic driving function on and off.

[0078] Furthermore, the driver is less likely to confuse the switching operation with another operation. Also, the second operating member 622 disposed to the right of the first operating member 621 can be operated by the driver in a position gripping the right side surface of the operating unit 62 (with the right hand). In this embodiment, the second operating member 622 is a seesaw switch, and in a position gripping the right side surface of the operating unit 62, the second operating member 622 can be easily and stably operated with, for example, the thumb. As a result, the operability of the operating unit 62 is improved.

[0079] Incidentally, in the display / operation device 6 according to this embodiment, the display unit 61 and the operation unit 62 are separate. That is, in this embodiment, the display unit 61 and the operation unit 62 are not integrated into one integral structure. In other words, the display unit 61 and the operation unit 62 are fixed separately to the machine body 11 in a mutually separated state. However, the display unit 61 and the operation unit 62 are electrically connected.

[0080] The support structure for the display unit 61 and the operation unit 62 will be described in detail below.

[0081] The working machine 10 according to this embodiment includes a body 11 having an automatic steering function, a display unit 61, and a support member 7. The display unit 61 displays at least information related to the automatic steering function. The support member 7 supports the display unit 61. The support member 7 has a first mounting portion 701 and a second mounting portion 702. The first mounting portion 701 is fixed to a first fixed portion 101 of the body 11. The second mounting portion 702 is fixed to a second fixed portion 102 separate from the first fixed portion 101 of the body 11. The first fixed portion 101 and the second fixed portion 102 are arranged on one side in the left-right direction D3 when viewed from the center of the body 11 in the left-right direction D3.

[0082] In short, in this embodiment, the display unit 61 of the display operation device 6 is supported by the body 11 via the support member 7. Here, the support member 7 is fixed to the body 11 at least at two locations, the first fixing portion 101 and the second fixing portion 102. Therefore, the fixing strength of the support member 7 to the body 11 can be increased compared to a case where the support member 7 is fixed to the body 11 at one location. Moreover, the first fixing portion 101 and the second fixing portion 102 are concentrated on one side of the left-right direction D3 as viewed from the center of the left-right direction D3 of the body 11. Therefore, compared to a case where the first fixing portion 101 and the second fixing portion 102 are distributed on both sides of the left-right direction D3 as viewed from the center of the left-right direction D3 of the body 11, the display unit 61 can be firmly supported while keeping the rigidity of the support member 7 itself low.

[0083] And, since the display unit 61 is supported on the aircraft body 11 using such a support member 7, the position of the display unit 61 is not limited to, for example, in front of the steering operation unit 41 (steering handle), and the display unit 61 can be relatively freely positioned. As a result, for example, it is possible to position the display unit 61 while avoiding a position where the display screen of the display unit 61 is difficult for the driver to see due to the angle of the steering operation unit 41, the driver's posture, the driver's physique, etc., and there is an advantage that the visibility of the display unit 61 can be easily improved.

[0084] In this embodiment, as described above, the display operation device 6 is disposed to the right of the steering operation unit 41. Since the steering operation unit 41 is disposed at the center of the left-right direction D3 of the aircraft 11, the support member 7 that supports the display unit 61 of the display operation device 6 is also disposed to the right as viewed from the center of the left-right direction D3 of the aircraft 11. Therefore, the first fixing portion 101 and the second fixing portion 102 for fixing the support member 7 are disposed on the right side in the left-right direction D3 as viewed from the center of the left-right direction D3 of the aircraft 11.

[0085] In this embodiment, the support member 7 that supports the display unit 61 also supports the operation unit 62 of the display operation device 6. That is, the work machine 10 according to this embodiment further includes an operation unit 62 that is supported by the support member 7. As described above, the operation unit 62 is a portion for performing operations related to at least the automatic steering function of the work machine 10.

[0086] As a result, the operation unit 62 is also supported on the aircraft body 11 by the support member 7, similar to the display unit 61, so that, for example, the arrangement of the operation unit 62 is not limited to the front of the steering operation unit 41 (steering handle), and the operation unit 62 can be arranged relatively freely. As a result, for example, it is possible to arrange the operation unit 62 while avoiding a position where the operation unit 62 is difficult for the driver to operate due to the angle of the steering operation unit 41, the driver's posture, the driver's physique, etc., and there is an advantage that the operability of the operation unit 62 can be easily improved.

[0087] Moreover, in this embodiment, the operation unit 62 and the display unit 61 are disposed apart from each other. That is, the display unit 61 and the operation unit 62 are supported by the common support member 7, but are disposed separately. Therefore, by making each of the display unit 61 and the operation unit 62 small, it is easy to dispose the display unit 61 and the operation unit 62 by utilizing dead space or the like.

[0088] Here, the operation unit 62 is disposed behind the display unit 61 in the front-rear direction D2. That is, from the perspective of a driver sitting behind the display operation device 6 (the display unit 61 and the operation unit 62), the operation unit 62 is located in front (closer) than the display unit 61, making it easier for the driver to operate the operation unit 62. That is, the driver can easily operate the operation unit 62 without having to change his / her posture, such as by leaning forward.

[0089] Hereinafter, a specific configuration of the support member 7 in this embodiment will be described with reference to FIGS.

[0090] In this embodiment, the support member 7 has a first support frame 71, a second support frame 72, a connecting member 73, a first stay 74, and a second stay 75, in addition to a first mounting portion 701 and a second mounting portion 702. Here, since the work machine 10 is used outdoors, all of the components of the support member 7 (the first support frame 71, etc.) are made of metal members that have been treated to be rust-proof.

[0091] The first support frame 71 is, for example, configured of a circular tubular member (round pipe) having a circular cross section. The first support frame 71 has a length at least along the up-down direction D1, and the first attachment portion 701 is joined to one end portion (lower end portion) thereof by joining means such as welding and / or adhesive.

[0092] The second support frame 72 is, for example, configured of a circular tubular member (round pipe) having a circular cross section. The second support frame 72 has a length at least along the up-down direction D1, and the second attachment portion 702 is joined to one end (lower end) thereof by joining means such as welding and / or adhesive.

[0093] 7 and 8, the connecting member 73 is a member that connects the first support frame 71 and the second support frame 72. Here, the connecting member 73 connects the upper end of the first support frame 71 and the upper end of the second support frame 72.

[0094] 8, the connecting member 73 has a first connecting portion 731 and a second connecting portion 732 that are fastened with fasteners such as bolts and nuts. The first connecting portion 731 is joined to an upper end portion of the first support frame 71 by a joining means such as welding and / or adhesive. The second connecting portion 732 is joined to an upper end portion of the second support frame 72 by a joining means such as welding and / or adhesive.

[0095] The first stay 74 is a member for attaching the display unit 61 to the support member 7. In this embodiment, the first stay 74 is disposed above the second support frame 72. Here, the first stay 74 supports the display unit 61 rotatably about a rotation axis Ax1 (see FIG. 8) along the left-right direction D3. This makes it possible for the display unit 61 to adjust the tilt angle of the display screen.

[0096] The second stay 75 is a member for attaching the operating unit 62 to the support member 7. In this embodiment, the second stay 75 is fixed to the upper end of the first support frame 71. The first stay 74 is fixed to the second stay 75, and thus the first stay 74 is indirectly fixed to the upper end of the first support frame 71. Here, the second stay 75 supports the operating unit 62 rotatably about a rotation axis Ax2 (see FIG. 7) along the up-down direction D1. This makes it possible to adjust the position of the operating unit 62 to a position that is easy to operate according to the driver.

[0097] The first mounting portion 701 joined to the lower end of the first support frame 71 is fixed to the first fixed portion 101 of the airframe 11, and the second mounting portion 702 joined to the lower end of the second support frame 72 is fixed to the second fixed portion 102 of the airframe 11, thereby fixing the support member 7 to the airframe 11. In other words, both ends of the first support frame 71 and the second support frame 72 connected by the connecting member 73 are fixed to the first fixed portion 101 and the second fixed portion 102 of the airframe 11 by the first mounting portion 701 and the second mounting portion 702, respectively.

[0098] In this embodiment, the first fixing portion 101 is a part of the right mudguard frame 54 of the pair of left and right mudguard frames 54. In other words, the first attachment portion 701 joined to the lower end portion of the first support frame 71 is fixed to the first fixing portion 101 provided on the right mudguard frame 54. As described above, the mudguard frame 54 has its lower end fixed to the floor 55 of the driver's section 5 and its other end fixed to the dashboard frame 57.

[0099] On the other hand, the second fixing portion 102 is the right end portion of the dashboard frame 57 (see FIG. 7) to which the dashboard 52 is attached. In other words, the second mounting portion 702 joined to the lower end portion of the second support frame 72 is fixed to the second fixing portion 102 provided on the dashboard frame 57. The dashboard frame 57 has a lower end portion fixed to the floor 55 of the driver's section 5 and protrudes upward from the floor 55.

[0100] In this manner, at least one of the first fixed portion 101 and the second fixed portion 102 is disposed on an auxiliary member that protrudes upward from the floor 55 of the driver's section 5 in the vehicle body 11. In this embodiment, the mudguard frame 54 is an example of an auxiliary member on which the first fixed portion 101 is provided, and the dashboard frame 57 is an example of an auxiliary member on which the second fixed portion 102 is provided. That is, in this embodiment, both the first fixed portion 101 and the second fixed portion 102 are disposed on auxiliary members (the mudguard frame 54 and the dashboard frame 57) that protrude upward from the floor 55.

[0101] As a result, while the display unit 61 (and the operating unit 62) is supported at a position higher than the floor 55, an auxiliary member that protrudes upward from the floor 55 is used to secure the support member 7, so no additional structure is required to secure the support member 7.

[0102] In this embodiment, the first attachment portion 701 is fastened to the first fixed portion 101 by fasteners such as bolts and nuts. Similarly, the second attachment portion 702 is fastened to the second fixed portion 102 by fasteners such as bolts and nuts. Therefore, the support member 7 can be attached to the airframe 11 at a later date, and can also be removed from the airframe 11.

[0103] In this embodiment, the first fixing portion 101 and the second fixing portion 102 are disposed at different positions in the up-down direction D1. That is, the first mounting portion 701 and the second mounting portion 702 of the support member 7 are fixed to the first fixing portion 101 and the second fixing portion 102 that are set at different heights on the machine body 11.

[0104] Specifically, the first fixing portion 101 provided on the mudguard frame 54 is disposed at a lower position (below) than the second fixing portion 102 provided on the dashboard frame 57. This makes it easier to improve the mounting strength of the support member 7 compared to a case in which the first mounting portion 701 and the second mounting portion 702 of the support member 7 are fixed at the same height.

[0105] Moreover, the first fixing portion 101 and the second fixing portion 102 are disposed at different positions from each other in a plan view. That is, the first attachment portion 701 and the second attachment portion 702 of the support member 7 are fixed to the first fixing portion 101 and the second fixing portion 102 that are set at different positions in the horizontal plane.

[0106] Specifically, the first fixing portion 101 provided on the mudguard frame 54 is disposed to the right (see FIG. 9) and forward (see FIG. 10) of the second fixing portion 102 provided on the dashboard frame 57. This makes it easier to improve the mounting strength of the support member 7 compared to a case in which the first mounting portion 701 and the second mounting portion 702 of the support member 7 are fixed at the same position in a plan view.

[0107] In this embodiment, the support member 7 has a shape that bulges out to one side in the left-right direction D3 (to the right in this embodiment) when viewed from the center of the left-right direction D3 of the aircraft body 11. That is, as shown in Fig. 9, a middle portion of the first support frame 71 in the up-down direction D1 has a curved shape that bulges outward in the left-right direction D3 (to the opposite side from the center) compared to its lower end and upper end.

[0108] As a result, a space is secured between the support member 7 (first support frame 71) and the dashboard 52 due to the shape that bulges out to one side in the left-right direction D3. Therefore, the driver sitting in the driver's seat 51 can view the steering wheel 111 on the right side through the space that is formed between the support member 7 (first support frame 71) and the dashboard 52 due to the shape that bulges out to one side in the left-right direction D3. In other words, the support member 7 is unlikely to get in the way when the driver views the steering wheel 111.

[0109] Moreover, the support member 7 includes a support frame (first support frame 71 and second support frame 72). The first mounting portion 701 is provided integrally with a closure plate 703 that closes one end face of the support frame (first support frame 71). That is, as shown in a balloon in FIG. 8, an opening on one end face on the lower end side of the first support frame 71 is closed by the closure plate 703 that is integrated with the first mounting portion 701. The closure plate 703 is joined by a joining means such as welding and / or adhesive.

[0110] This allows a sufficient welding margin (and / or adhesive margin) to be secured when the first mounting portion 701 is joined to the support frame (first support frame 71) by welding and / or adhesive, thereby improving the mounting strength of the first mounting portion 701 to the support frame (first support frame 71).

[0111] Moreover, the work machine 10 according to this embodiment further includes a mirror 8 supported by the support member 7. The mirror 8 is a side mirror (rear-view mirror) used by the driver sitting in the driver's seat 51 to check behind, and is disposed at the right end of the machine body 11. Specifically, the mirror 8 is fixed to the tip of a mirror arm 81 extending upward from the upper surface of the first connecting portion 731 (see FIG. 8) of the connecting member 73, and is supported by the support member 7 via the mirror arm 81.

[0112] As a result, the support member 7 for supporting the display unit 61 (and the operation unit 62) also serves to support the mirror 8, so that there is no need to provide a separate member for supporting the mirror 8.

[0113] Here, the mirror 8 is disposed on one side (the right side) in the left-right direction D3 as viewed from the display unit 61. That is, the mirror arm 81 extends rightward from the support member 7 (the connecting member 73 thereof).

[0114] In this way, by positioning the mirror 8 on the outer side (right side) of the display unit 61 in the left-right direction D3, the display unit 61 is unlikely to be reflected in the mirror 8 when the driver sitting in the driver's seat 51 looks at the mirror 8.

[0115] Furthermore, at least a part of the mirror 8 is disposed at the same position as the display unit 61 in the up-down direction D1. That is, at least a part of the mirror 8 is disposed at the same height as the display unit 61.

[0116] This allows the driver sitting in the driver's seat 51 to view both the mirror 8 and the display unit 61 with a relatively small amount of eye movement.

[0117] [4] Variations Below, we will list some modified examples of the embodiment 1. The modified examples explained below can be applied in appropriate combinations.

[0118] The control system 1 in the present disclosure includes a computer system. The computer system is mainly composed of one or more processors and one or more memories as hardware. The functions of the control system 1 in the present disclosure are realized by the processor executing a program (a control program for a work machine) recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, or may be recorded and provided on a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that is readable by the computer system. In addition, some or all of the functional units included in the control system 1 may be configured with electronic circuits.

[0119] Furthermore, it is not essential for the control system 1 that at least some of the functions of the control system 1 are concentrated in one housing, and the components of the control system 1 may be distributed across multiple devices (e.g., the control device 2 and the terminal device 3). Conversely, the functions distributed across multiple devices in the first embodiment may be concentrated in one housing. Furthermore, at least some of the functions of the control system 1 may be realized by the cloud (cloud computing) or the like.

[0120] Furthermore, it is not essential that the display operation device 6 is disposed to the right of the steering operation unit 41, and for example, the display operation device 6 may be disposed to the left of the steering operation unit 41. In this case, the first fixing part 101 and the second fixing part 102 are disposed on the left side as viewed from the center of the fuselage 11 in the left-right direction D3.

[0121] Furthermore, it is not essential that the support member 7 has the first support frame 71 and the second support frame 72. For example, the support member 7 may be configured with one continuous support frame. Conversely, the support member 7 may have three or more support frames.

[0122] Furthermore, it is not essential that the second mounting portion 702 of the support member 7 is fixed to the dashboard frame 57. For example, when the dashboard 52 itself has sufficient strength, the second mounting portion 702 may be fixed to the dashboard 52. In this case, the second fixing portion 102 to which the second mounting portion 702 is fixed is provided on the dashboard 52, and the dashboard 52 becomes an example of an auxiliary member that protrudes upward from the floor 55.

[0123] Furthermore, the arrangement of the first operating member 621 and the second operating member 622 in the operating unit 62 is not limited to the arrangement described in embodiment 1. For example, the first operating member 621 may be arranged farther from the steering operating unit 41 than the second operating member 622.

[0124] Furthermore, the first operating member 621 is not limited to a push button switch, and may be, for example, a lever switch, a slide switch, a rotary switch, a touch switch, etc. Similarly, the second operating member 622 is not limited to a seesaw switch, and may be, for example, a lever switch, a slide switch, a rotary switch, a touch switch, etc.

[0125] Furthermore, the terminal device 3 is not limited to a general-purpose terminal such as a tablet terminal, smartphone, or laptop computer, but may be configured as a dedicated terminal. Furthermore, multiple terminal devices 3 may be associated with one work machine 10, in which case one work machine 10 can be controlled by multiple terminal devices 3. Conversely, one terminal device 3 may be associated with multiple work machines 10, in which case multiple work machines 10 can be controlled by one terminal device 3.
