Description

Route Setting Apparatus and Method Based on Driving History for Autonomous Driving The present invention relates to a driving path setting technology for an autonomous vehicle, and more specifically, to a driving history-based path setting device and method for an autonomous vehicle. Since autonomous vehicles can operate on their own without intervention from a driver or passengers, they must perceive their surrounding environment and location to generate a route that enables safe and efficient driving. In order for a driver to drive along a safe and efficient route, autonomous vehicles require technology that sets the driving path by comprehensively considering various factors such as time and cost to the destination. The background technology of the present invention is disclosed in Korean Registered Patent No. 10-2350197. FIGS. 1 and 2 are drawings briefly illustrating a driving history-based path setting device for autonomous driving according to an embodiment of the present invention. FIG. 3 is a drawing relating to a judgment unit according to an embodiment of the present invention. FIG. 4 is a drawing relating to a control unit according to an embodiment of the present invention. FIG. 5 is a diagram relating to a driving history-based path setting method for autonomous driving according to an embodiment of the present invention. FIG. 6 is a diagram for determining the ranking of a driver's route selection criteria using driver driving history data according to an embodiment of the present invention. FIG. 7 is a diagram illustrating the process of selecting a final path by comparing paths from a driver's current location to a destination during autonomous driving according to an embodiment of the present invention. The present invention is susceptible to various modifications and may have various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the invention. Furthermore, singular expressions used in this specification and claims should generally be interpreted as meaning "one or more" unless otherwise stated. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing with reference to the accompanying drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. In the present invention, a "vehicle" is any device used for the movement of a passenger using an engine and/or an electric motor as a power source. For example, various types of vehicles moving on land (e.g., passenger cars, buses, trams, trains, motorcycles, trolleys, etc.), various types of boats moving on rivers, lakes, or seas, and various types of devices moving in the air (e.g., airplanes, helicopters, drones, etc.) may be vehicles of the present invention. FIGS. 1 and FIGS. 2 are drawings briefly illustrating a driving history-based path setting device for autonomous driving according to an embodiment of the present invention. A driving history-based path setting device (10) for autonomous driving according to an embodiment of the present invention may be mounted on a vehicle (20). Referring to FIG. 1, a driving history-based route setting device (10) for autonomous driving receives a GPS (30) signal mounted on a vehicle (20) to determine the location of the driver and the location of the destination entered by the driver. Additionally, a central control server (40) collects external situation information from the driver to the destination using V2X (Vehicle-to-Everything) communication and determines the driving route situation. The driving history-based route setting device (10) for autonomous driving can compare the cost, time required, and convenience of driving routes to the destination and recommend a driving route suitable for the driver's tendencies using the driver's driving history data (50). Referring to FIG. 2, a driving history-based path setting device (10) for autonomous driving includes an input unit (210), an information collection unit (230), a judgment unit (250), and a control unit (270). The input unit (210) can receive driver data directly from the driver using various interfaces. The interfaces may include a HUD (Head-Up Display), a touchscreen, a voice system, a physical button, a smartphone, and a camera, and the driver data received may be at least one of a destination, a preferred route to the destination and an acceptable route cost, an acceptable driving time,
