Abstract: Mechatronics is synergistic integration of mechanical engineering, with electronics and intelligent computer control in the design and manufacturing of industrial products and processes. Automobile (auto car, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor) is a mechatronic system which served as major means of transportation around the world. Virtually all community has a need for automobile. This makes automobile issues as related to diagnostic and repair interesting to all communities. Consequent to the diversification of skill in diagnosing automobile faults and approaches in solving some problems and innovation in automobile industry. It is appropriate to say that repair and diagnostic of automobile will be better enhanced if community has opportunity of sharing knowledge and idea globally. This paper discussed the desirable elements in automobile as mechatronics system and present conceptual framework of virtual community model for knowledge sharing among automobile users. Keywords: automobile, automobile users, knowledge sharing, mechatronics system, virtual community.

INTRODUCTION

An automobile, auto car, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. [1] Mechatronics, the term coined in Japan in the 1970s, has evolved over the past 25 years and has led to a special breed of intelligent products. The word, mechatronics, is composed of ―mecha‖ from mechanism and the ―tronics‖ from electronics [2].

In other words, technologies and developed products will be incorporating electronics more and more into mechanisms, intimately and organically, and making it impossible to tell where one ends and the other begins [3,4]. Harashima, Tomizuka, and Fukada in 1996 defined mechatronics as the synergistic integration of mechanical engineering, with electronics and intelligent computer control in the design and manufacturing of industrial products and processes [4]. Mechatronics is a methodology used for the optimal design of electromechanical products. In recent time mechatronic system is not just a marriage of electrical and mechanical systems and is more than just a control system; it is a complete integration of all of them.

In this paper the authors sees community as a group of people living in the same place or having a particular characteristic in common. A virtual community is an aggregation of individuals who interact around a shared interest, where interaction is supported and/or mediated by technology and guided by some protocols or norms. [6,7] Virtual community can be dedicated to a specific topic, or seek to bring people with similar interest or philosophies together, it supports many to many media communication and there is no geographic boundary or physical contact [8]. This paper is focus on designing of KnowledgeBased Virtual Community System (KBVCS) For Enhancing Knowledge Sharing in Mechatronics System Diagnostic and Repair with particular interest to automobile. A. Statement of Problem Diagnostic and repair of automobile products required a synergistic collaboration among the stakeholders (automobile owners, drivers, automobile apprenticeship and conventional mechanics). This system (KBVCS) will provide virtual platform to enhance such collaboration and hence make information readily available. B. Aims and Objectives This research work is aimed at achieving the following objectives  To provide a conceptual framework for using virtual community for collaborations among stakeholders in automobile diagnostic and repair  To provide evidences to support the fact that automobile is a mechatronic system  To provide information (tutorials) for training of automobile apprentices  To provide avenue for decongestion of conventional automobile workshop

 To provide an interactive network for the exchanges of ideas among stakeholders in diagnosing and repair of automobile system through real-time conversation through text and voice. C. Scope of the study This work will cover the sharing of information and collaboration among stakeholders in automobile millennium cars. 1.

BACKGROUND TO THE STUDY 1.1 Automobiles as a Mechatronic System In the late 1970s, the Japan Society for the Promotion of Machine Industry (JSPMI) classified mechatronics products into four categories [1]: Class I: Primarily mechanical products with electronics incorporated to enhance functionality, Class II: Traditional mechanical systems with significantly updated internal devices incorporating electronics with the external user interfaces are unaltered, Class III: Systems that retain the functionality of the traditional mechanical system, but the internal mechanisms are replaced by electronics, and Class IV: Products designed with mechanical and electronic technologies through synergistic integration. The evolution of modern mechatronics can be illustrated with the example of the automobile. Until the 1960s, the radio was the only significant electronics in an automobile. All other functions were entirely mechanical or electrical, such as the starter motor and the battery charging systems. There were no intelligent safety systems,‖ except augmenting the bumper and structural members to protect occupants in case of accidents. Seat belts, introduced in the early 1960s, were aimed at improving occupant safety and were completely mechanically actuated. ICCM 2014, November 24-26, 2014, Dubai, UAE

The Antilock Brake System (ABS) was also introduced in the late 1970s in automobiles [7]. The ABS works by sensing lockup of any of the wheels and then modulating the hydraulic pressure as needed to minimize or eliminate sliding. The Traction Control System (TCS) was introduced in automobiles in the mid1990s. The TCS works by sensing slippage during acceleration and then modulating the power to the slipping wheel. This process ensures that the vehicle is accelerating at the maximum possible rate under given road and vehicle conditions. The Vehicle Dynamics Control (VDC) system was introduced in automobiles in the late 1990s. The VDC works similar to the TCS with the addition of a yaw rate sensor and a lateral accelerometer [7]. The driver intention is determined by the steering wheel position and then compared with the actual direction of motion. The TCS system is then activated to control the power to the wheels and to control the vehicle velocity and minimize the difference between the steering wheel direction and the direction of the vehicle motion [8].

METHODOLOGY AND FRAMEWORK Analysis of the proposed System

The system shall be a web-based and a database driven with expert system shell and knowledge-based section of artificial intelligence for knowledge extraction that is completely updatable by the various categories of users. The proposed system model is as shown in figure 1 below.

B. Proposed System Users There will be four (4) categories of users which are:    

Conventional expert mechanics Drivers Automobile owners Automobile apprentice

The various operations that the users can perform are; registration, post problems, post repair tips, meet experts, invite experts, post tutorials and view tutorials. Every user must first of all register and their information stored in the data based before sign-in to perform any of the operation mentioned. Conventional expert mechanics can perform operations which includes; posting of tutorials, posting repair tips and solution, and collaboration among other stakeholders. Drivers and automobile owners can performs operation like viewing post (such as repair and ICCM 2014, November 24-26, 2014, Dubai, UAE

PROPOSED DESIGN AND IMPLEMENTATION Choice of Programming Language

The choice of programming language will be PHP (Hypertext pre-processor) for server-side scripting, JavaScript and HTML for media content management and MYSQL as the backend database. In addition, these technologies are open-sourced and are available for download for free of charge or come packaged with most if not all browsers, as they are the rendering interfaces for all web based applications. B.

Input Design

The input design depicts the means and methods through which users or the administrator passes data to the system for processing. It involves the GUI (graphical userinterface) which employs form tools such as textboxes, selection boxes, input fields and a host of other HTML form tools that allow the user or administrator to interact with the system without necessarily following a predefined order. The user interaction with the system starts at the home page where the user enters data for sign-up and later sign-in to perform the operations mentioned. C.

D.

This stage involves the various aspects that would be considered in order to put the new system to proper use and for it to deliver effectively and efficiently. It considers the factors that affect the successful running of the new system which includes: hardware requirement, software requirement, human ware (users), testing, and documentation. E. Hardware requirement The infrastructure needed to run the Knowledge-Based Virtual Community System (KBVCS) shall include high computation capability (i.e. CPU) due to client request and Asynchronous request processing referring to AJAX technology, minimal volume of storage device in gigabyte (GB) range to provide space for the impending large database of information, large bandwidth to compensate for high internet traffic and client connections. The aforementioned facilities are provided by the hosting service at a rent. However, the clients/users (the administrators and users) accessing the solution should have the following minimum requirements.  A multimedia enabled Personal Computer (PC) or Personal Digital Assistant (PDA).  A modem/DSL for internet connection  Prior minimal knowledge in the case of the client on internet use and professional internet and application knowledge on the path of the administrator.

OUTPUT DESIGN

The output defines the way the system responds to users interactions. It shows the various means it uses to present information to the users for decision making. The system presents information to users based on their interaction from the home page’s and other related pages. The user can then view more information and perform more searches from there; they can as well choose the information that is relevant to their search criteria.

Implementation

Consequent to dynamism and nature of complex information required in maintenances, diagnosing and repair of automobiles in modern age of mechatronic, widespread usage and application of automobile across the globe. This proposed Knowledge-Based Virtual Community System (KBVCS) will be of sinqua-non benefits for collaborations and sharing of information among the stakeholders in diagnosing and repair of automobile system. The system if designed and implemented it will reduce congestion in a conventional motor mechanics workshop. However for the successful implementation of the virtual community, we recommended that government must be a partnership in progress by making available infrastructure such as electricity power supply, data communication and transmission devices at subsidy rate, and individual level of ICT literacy should be upgraded. Also the automobile industry and movement should embark on public awareness on the need for knowledge sharing and its associated benefit
