[Background technology]

[0002] Many autonomous vehicles generate wide-area routes according to the destination selected by the passenger or driver, and generate local routes for obstacle avoidance and overtaking to perform route tracking. All of these processes are performed inside the vehicle.

[0003] However, autonomous operation systems must apply technology that is differentiated from existing autonomous vehicle methods. Autonomous operation is defined as a system that automatically drives a specified route defined for performing a task, either performing the task itself or with the assistance of a human operator.

[0004] To achieve this, the control system is used to generate the work route for each autonomous work vehicle, which is then transmitted to the platform via wireless communication, and the autonomous work is carried out through route tracking. In addition, multiple autonomous work vehicles must work simultaneously or in cooperation with each other.

[0005] In particular, for vehicles that perform autonomous driving and work for special purposes, such as shuttle buses, special-purpose vehicles, construction and agricultural machinery, and golf carts, real-time route regeneration technology must be applied to hand over work to other platforms according to the work status of each autonomous work system, such as battery discharge or a cleaning vehicle's collection bin being full.

[0006] However, conventional technology only controlled operations to maintain a certain distance between each platform based on their positions, and there was no control system that could control specific events occurring on multiple platforms in real time.

BEST MODE FOR CARRYING OUT THEINVENTION

[0029] Various preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art, and the following embodiments may be modified into various other forms, and the scope of the present invention is not limited to the following embodiments. Rather, these embodiments are provided to make the present disclosure more complete and complete, and to fully convey the concept of the present invention to those skilled in the art. Hereinafter, the embodiments of the present invention will be described with reference to the drawings that show an ideal embodiment of the present invention.

[0031] Hereinafter, a special-purpose multi-platform may be defined as a vehicle that receives route and operation information sent from a control system, performs autonomous driving and operation based on the route and operation information, and transmits the operation result to the control system. For example, the special-purpose multi-platform may include a golf cart, an unmanned vacuum cleaner, a shuttle bus, a special-purpose vehicle, a construction / agricultural machine, etc.

[0032] In the following, the special purpose multiple platform can be defined as vehicles that receive route and operation information transmitted from one control system being regarded as one crowd and differentiated from vehicles other than the crowd.

[0033] FIG. 1 is a diagram illustrating the structure of a control system for controlling autonomous work of multiple unmanned work objects in one embodiment of the present invention, and FIG. 2 is a diagram for explaining a method of generating a work area and a work path by a work information generation unit in one embodiment of the present invention.

[0034] Referring to Fig. 1, a control system 100 for controlling autonomous operations of a plurality of unmanned work objects according to an embodiment of the present invention includes a work information generating unit 10, a work instruction control unit 20, and a data processing unit 30. Here, the plurality of unmanned work objects refer to vehicles or platforms capable of autonomous driving and autonomous operations having special purposes, such as shuttle buses, special-purpose vehicles, construction and agricultural machinery, and golf carts. All data processed by the control system 100 and status information data of the plurality of unmanned work objects are transmitted and received with each component using a wireless communication method.

[0035] The work information generating unit 10 selects and divides a work area as shown in (a) of Fig. 2. Then, the work information generating unit 10 determines the number of unmanned work objects that will actually perform autonomous work simultaneously among the plurality of unmanned work objects. According to the determined number of unmanned work objects, the work information generating unit 10 divides the area in which each unmanned work object performs work, and generates a work path so that each unmanned work object can efficiently perform autonomous work.

[0036] In addition, the work information generating unit 10 performs a function of correcting the work area and the work path when an event occurs in any one of the unmanned work objects performing autonomous work. The work instruction control unit 20 and the data processing unit 30 will be described below, and the work information generating unit 10 will be described in detail later.

[0037] The working area may use an image stored using a web server. The image may include a satellite image or an aerial image via a satellite. The image may include location information consisting of outermost coordinate points. An autonomous work start point may be selected according to the location information, and a work path may be generated based on the start point. The work path may be generated so as to proceed sequentially for each unmanned work object. Alternatively, after setting a plurality of autonomous work start points, a plurality of work paths for the unmanned work object may be generated based on each start point, so that autonomous work can be performed simultaneously.

[0038] The work instruction control unit 20 can control the entirety of the multiple unmanned work objects, and can also control any part of the multiple unmanned work objects so that they perform autonomous work along the work path generated by the work information generation unit 10. At this time, the work instruction control unit 20 collects position information of the unmanned work objects during work in real time. The collected position information of the unmanned work objects is transmitted to the data processing unit 30 in real time.

[0039] Specifically, the work instruction control unit 20 transmits autonomous work command information to at least one of the plurality of unmanned work objects so that the autonomous work can be performed along a work path generated based on the work area determined by the work information generation unit 10.

[0040] The unmanned work object receives the autonomous work command information and performs autonomous work along the determined work path. The unmanned work object performing autonomous work transmits status information data of the unmanned work object in real time to the data processing unit 30 along with information on the currently working work area and work path. Here, the status information data includes the position, work speed, work amount, operation and function information of the unmanned work object, and the function information includes functional information of the platform itself such as the remaining battery level of the platform, malfunctions, etc. All status information data of not only the unmanned work object in operation but all unmanned work objects on standby for autonomous work managed by the control system 100 is transmitted to the data processing unit 30.

[0041] In addition, in the work instruction control unit 20, when an unmanned work object performing the autonomous work is accompanied by a worker, the unmanned work object can be controlled to perform a function of assisting the worker's work by recognizing the worker using the worker recognition device provided on the unmanned work object.

[0042] The data processing unit 30 includes an event information generating unit 32 and an event information processing unit 34, and collects status information data of the plurality of unmanned operation objects in real time and processes the collected status information data.

[0043] The event information generating unit 32 judges the status information data collected in real time, and when an abnormality occurs in any of the unmanned work objects performing autonomous work, generates this as event information.

[0044] The event information processing unit 34 performs a function of transmitting an autonomous work confirmation signal to the work information generating unit so that the work path in the work area can be confirmed and corrected according to the event information generated by the event information generating unit 32, or transmitting an alternative work command signal to the work instruction control unit so that the interrupted work can be continuously performed by controlling another unmanned work object adjacent to any one of the unmanned work objects.

[0045] Specifically, the event information generation unit 32 performs the function of determining whether the status information data provided in real time from the unmanned work object performing autonomous work is a temporary sensor error or an inoperable state of the unmanned work object.

[0046] For example, if a temporary sensor error is determined based on the status information data, the event information generation unit 32 can instruct the work instruction control unit 20 to continue the work, or can instruct maintenance of the unmanned work object to replace the sensor of the unmanned work object.

[0047] If it is determined that the unmanned work object is in an inoperable state based on the status information data, the event information generation unit 32 generates event information including the status information data of the unmanned work object, and information on the work area and work route in which the unmanned work object was operating, and transmits this to the event information processing unit 34.

[0048] The data processing unit 30 can compare the initial work information of the unmanned work object with the status information data of the unmanned work object performing the autonomous work in real time, and determine the work error of the unmanned work object.

[0049] If the work error occurs, the data processing unit 30 can transmit work error occurrence information to the work instruction control unit 20, and the work instruction control unit 20 can control the unmanned work object to re-perform the work so that the unmanned work object completes the work. Alternatively, if the work error occurs, the data processing unit 30 can transmit work error occurrence information to the work information generation unit 10, and the work information generation unit 10 can complement the initial work information and regenerate the complemented work area and work path based on the point where the work error by the unmanned work object occurred. Thereafter, the regenerated work area and work path information can be transmitted to the work instruction control unit 20, and the work instruction control unit 20 can control the unmanned work object to perform autonomous work along the complemented work area and work path.

[0050] The functions performed by the control system 100 will be described in detail below with reference to FIGS.

[0051] 3 and 4 are diagrams illustrating a control system for controlling the autonomous work of a plurality of unmanned work objects according to an embodiment of the present invention, and a structure for controlling a plurality of unmanned work objects.

[0052] For example, the control system 100 may collect status information data of a first unmanned work object 210 performing an autonomous operation and a second unmanned work object 220 not performing an autonomous operation in real time, as shown in Fig. 3, and process the collected status information data. Alternatively, the control system 100 may collect status information data of a first unmanned work object 210 performing an autonomous operation and a second unmanned work object 220 performing an autonomous operation at a certain distance from the first unmanned work object 210 in real time, and process the collected status information data.

[0053] When a specific event occurs in the first unmanned work object 210, the data processing unit 30 can analyze the state information data of the first unmanned work object 210 collected by the event information generating unit 32 and generate event information through a discrimination process thereon. Based on the generated event information, the event information processing unit 34 transmits an autonomous work confirmation signal to the work information generating unit 10 to confirm and correct the work path in the work area. In response to the transmitted autonomous work confirmation signal, the work information generating unit 10 complements and corrects the work area and the work path, and transmits the signal to the work instruction control unit 20. The work instruction control unit 20 can control the second unmanned work object 220 adjacent to the first unmanned work object 210 along the transmitted work area and work path to continuously perform the interrupted work.

[0054] Alternatively, based on the generated event information, the event information processing unit 34 can directly transmit an alternative work command signal to the work instruction control unit 20, and the work instruction control unit 20 can control the second unmanned work object 220 adjacent to the first unmanned work object 210 to continuously perform the interrupted work.

[0055] 4, the control system 100 can control not only a platform for one specific purpose, but also a platform for a mixture of various specific purposes. For example, the control system 100 can simultaneously control a cleaning vehicle, a special vehicle, a construction / agricultural machinery vehicle, a golf cart, etc., and generate different work areas and autonomous work paths according to the type of autonomous work performed by each vehicle, and efficiently control the vehicles based on the different work areas and autonomous work paths.

[0056] Since the status information data of each platform is transmitted and received wirelessly, the location of the control system 100 can be configured anywhere. The control system 100 according to an embodiment of the present invention is a host system of small-scale control systems divided according to special purposes, and can be configured to monitor and control the small-scale control systems in real time by constructing a central control system.

[0057] FIG. 5 is a process flow chart that is generally illustrated to explain a method for controlling autonomous operations of a plurality of unmanned work objects according to one embodiment of the present invention.

[0058] Referring to FIG. 5, a method for controlling autonomous work of a plurality of unmanned work objects according to one embodiment of the present invention (S100) may include a step of generating and modifying a work path (S110), a step of transmitting autonomous work command information (S120), and a step of processing status information data (S130).

[0059] Specifically, the method is a method for controlling the autonomous work of multiple unmanned work objects using a control system, and first, a step (S110) of receiving information about a work area and generating and modifying work paths for the multiple unmanned work objects in the work area is performed.

[0060] Then, a step (S120) can be performed of transmitting autonomous work command information to at least one of the plurality of unmanned work objects so that the autonomous work can be performed along the work path generated based on the work area.

[0061] A step (S130) of collecting status information data of the plurality of unmanned operation targets in real time and processing the collected status information data may be performed.

[0062] The data processing step (S130) may include an event information generating step of determining the collected status information data and generating the collected status information as event information when an abnormality occurs in any of the unmanned work objects performing autonomous work, and an event information processing step of transmitting an autonomous work confirmation signal to a work information generating unit so that the work path in the work area can be confirmed and corrected according to the generated event information, or transmitting an alternative work command signal to a work instruction control unit so that another unmanned work object adjacent to any of the unmanned work objects can be controlled to continuously perform the interrupted work.

[0063] In the event information generation step, if a temporary sensor error is determined based on the status information data, the unmanned work object can be controlled to continue performing work or to perform maintenance on the unmanned work object.

[0064] In the event information generation step, if it is determined that the unmanned work object is in an inoperable state based on the status information data, event information can be generated according to the generated event information, including status information data of the unmanned work object, and information on the work area and work route that the unmanned work object was performing.

[0065] Here, the status information data includes information on the positions, work speeds, work amounts, operations, and functions of the plurality of unmanned work objects, and is transmitted using a wireless communication method.

[0066] In the work instruction control unit, when the unmanned work object performing the autonomous work is accompanied by a worker, the unmanned work object can be controlled to perform a function of assisting the worker's work by recognizing the worker using the worker recognition device provided on the unmanned work object.

[0067] In the data processing step, the initial work information of the unmanned work object can be compared in real time with status information data of the unmanned work object performing the autonomous work, thereby determining the work error of the unmanned work object.

[0068] If the work error occurs, the work instruction control unit can be controlled to instruct the unmanned work object to retry the work so that the unmanned work object completes the work. Alternatively, if the work error occurs, the work information generation unit can complement the initial work information, regenerate the complemented work area and work path based on the point where the work error occurred by the unmanned work object, and control the unmanned work object to perform autonomous work along the regenerated work area and work path.

[0069] As described above, the control system 100 according to an embodiment of the present invention can select a work area according to the number of work platforms and generate a work route. Each platform transmits the platform status (battery, malfunction, etc.) and work status to the control system 100 via wireless communication. In addition, the position information of other platforms can be shared via the control system 100.

[0070] Furthermore, the platform performing the autonomous operation receives an autonomous operation route from the control system 100, performs the autonomous operation through path tracking, and transmits the platform status and operation status to the control system 100. The control system 100 monitors the traveling status of the autonomous operation platform, recognizes a situation where charging is required or the operation cannot be performed any more, and regenerates and transmits the route in real time so that the operation can be assigned to another platform.

[0071] A number of autonomous work platforms can recognize each other's positions through the control system 100, and can control the distance and speed of each other based on this to prevent collisions. In the case of autonomous work with a specific purpose such as cleaning roads and collecting garbage, the autonomous work platform assists the worker by following the worker through a device that recognizes the worker. The driving route for the autonomous work can also be manually configured so that the autonomous work can be performed based on the trajectory and speed information through the driver's driving.

[0072] Through the control system 100 having such functions, it is possible to maximize the efficiency of work and driving in fields where control-based autonomous work can be applied, such as unmanned road sweeping, unmanned garbage collection, autonomous shuttles and golf carts. In addition, the driving and working status of all autonomous work platforms can be monitored in real time by the control system 100, which can increase the convenience of operation through maintenance and charging management using the same.

[0073] The present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of protection of the present invention should be determined by the technical ideas of the appended claims. [Explanation of symbols]
