Abstract

A repair search system proposing a repair method corresponding to a trouble code, the repair search system includes a microprocessor and a memory coupled to the microprocessor. The memory has a database storing the trouble code and the repair method performed in a past in association with each other. The microprocessor is configured to perform: by using a plurality of different search conditions created with the trouble code of a troubled vehicle as a reference, searching the database for a plurality of repair methods corresponding to the trouble code by every search condition; scoring each of repair method groups included in a search result acquired by every search condition; and outputting information indicating a repair method group with a highest score among the repair method groups.

3 . The repair search system according to claim 1 , wherein the list is a first list, and the display signal includes a signal for displaying a second list obtained by arranging a component part of a repair object corresponding to each of the repair methods included in the first list.
4 . The repair search system according to claim 1 , wherein the microprocessor is configured to perform the scoring including scoring each of the repair method groups included in the search result acquired for each search condition such that a repair method with a higher ratio of a number of repair success cases occupied in a number of repair cases is scored to be higher.
5 . The repair search system according to claim 1 , wherein the microprocessor is configured to perform the scoring including scoring each of the repair method groups included in the search result acquired for each search condition such that a repair method with a larger number of repair success cases is scored to be higher.
6 . The repair search system according to claim 1 , wherein the microprocessor is configured to perform the scoring including, in a case where each of the repair method groups included in the search result acquired for each search condition is scored, arranging repair methods included in each of the repair method groups in descending order based on a number of repair success cases, selecting, from the repair methods arranged in descending order, high-ranking repair methods corresponding to a predetermined ratio of a number of repair success cases with respect to a total number of repair success cases of the repair methods, and scoring each of the repair method groups to be higher, as a number of repair methods selected in the selecting is smaller.
7 . The repair search system according to claim 1 , wherein a plurality of pairs associated with the trouble code and the repair method with each other on a one-to-one basis are stored in the database.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2023-050890 filed on Mar. 28, 2023, the content of which is incorporated herein by reference. BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a repair search system for searching an appropriate repair method. Description of the Related Art As a technique for searching, there is a known technique for searching the entire text of article data simultaneously in parallel with use of a plurality of different search conditional expressions and providing a result that matches a search conditional expression (for example, see JP 2002-157270 A). In such a conventional technique, in a case where a large number of articles match a search condition, it is necessary for a user to narrow down the number of articles by, for example, changing the search conditional expression. In addition, the conventional technique is not related to a technique for searching for a repair method. SUMMARY OF THE INVENTION An aspect of the present invention is a repair search system proposing a repair method corresponding to a trouble code, the repair search system including a microprocessor and a memory coupled to the microprocessor. The memory has a database storing the trouble code and the repair method performed in a past in association with each other, and the microprocessor is configured to perform: by using a plurality of different search conditions created with the trouble code of a troubled vehicle as a reference, searching the database for a plurality of repair methods corresponding to the trouble code by every search condition; scoring each of repair method groups included in a search result acquired by every search condition; and outputting information indicating a repair method group with a highest score among the repair method groups. BRIEF DESCRIPTION OF THE DRAWINGS The objects, features, and advantages of the present invention will become clearer from the following description of embodiments in relation to the attached drawings, in which: FIG. 1 is a diagram illustrating an example of a repair method list acquired by a repair search system; FIG. 2 is a schematic diagram illustrating a configuration of the repair search system; FIG. 3 is a flowchart for describing an example of processing of creating the repair method list in FIG. 1 to be performed in the repair search system in FIG. 2; FIG. 4 is a diagram illustrating search conditions; FIG. 5 is a diagram illustrating relaxing of the search conditions; and FIG. 6 is a flowchart for describing an example of processing of creating another repair method list. DETAILED DESCRIPTION OF THE INVENTION Hereinafter, embodiments of the invention will be described with reference to the drawings. <Outline of Repair Search System> A repair search system according to an embodiment of the present invention proposes an appropriate repair method so that a vehicle of a repair object can be repaired at one time. For example, with use of a database in which repair records about vehicles in the past are stored, a plurality of repair methods that have been searched for, based on a diagnostic trouble code (DTC) obtained from the vehicle of the repair object are output to a terminal of a user (a mechanic who performs maintenance work of the vehicle in a maintenance factory or the like). In order to propose a more appropriate repair method to the user, the repair search system adopts a search condition of a database, based on a score result obtained by scoring a search result. With such a configuration, from an enormous number of repair records stored in the database, a repair method that matches the DTC of the vehicle of the repair object is searched for, and in addition, a plurality of repair methods each having a high-repair success rate are narrowed down, and are proposed to the user. FIG. 1 is a diagram illustrating an example of a repair method list proposed by the repair search system. The repair method list is listed, for example, as component part information of a component part that should be replaced or adjusted (hereinafter, referred to as an object component part), and is displayed on a display unit of the terminal used by the user. The repair method list includes at least a component part number (Parts number) column, a component part name (Parts Name) column, a treatment (Treatment) column, and a repair success rate (Repair Success) column for an object component part. On the display unit, information of a vehicle (Vehicle Information) and a search condition (Search Condition) are displayed together with the repair method list. As an example of the information of the vehicle, a vehicle identification number (Vehicle Identification Number: referred to as VIN), a model name (Model), a model year (Model Year), and a factory of manufacture (Factory) are displayed. Note that in general, the VIN includes information
