Product System Case Study Analysis

Introduction

To fasten product development and reduce costs, the current mainstream of automotive structure development is moving toward the combination mode (e.g. common chassis). In addition, from the gradually increasing number of automobiles worldwide each year, it can be seen that the automobile has become an indispensable transportation tool for humans. All the know-how and techniques related to automobile maintenance/repair have become important topics in the industry. Generally speaking, the chassis is used to carry all the modules of the vehicle, support the vehicle weight, transmit the power generated by the engine to the driving wheel, and create a comfortable and safe driving environment.

The technology for equipment fault diagnosis (e.g. machine, vehicle, etc.) has been developed in response to the demands of modern industry that has been concerned with such aspects as human safety, economic productivity, and effectiveness. Auto repair manuals are still main reference to technicians in automotive diagnosis and repairing at present. As for the repair tutorial module, it is developed by automobile companies or software consultants for the properties and functions of special cars. It is not only expensive but integration of platform (operating system) and information sharing are impossible (About.com, 2006; AUTOTECH, 2006; Inner Auto Parts, 2006). Equipment fault diagnosis refers to the process of identifying equipment's operating condition and investigating its possible source of fault (Tse et al., 1996).

Therefore, the troubleshooting task system developed in this study is centered on automotive chassis. This study adopts the currently widely used technologies of Internet, virtual interaction and knowledge-based approach to develop a troubleshooting task platform of automobile chassis. This platform can provide important references about chassis troubleshooting for students, new employees and repairing technicians in the automobile industry through virtual interactive interface before their hand-on operations with real automobiles. This platform can also be significantly helpful for drivers in enhancing their knowledge about automobile maintenance/repair and consequently ensuring better driving safety.

Commercial Method

There are two types of TPMS on the market, direct-reading and indirect. Indirect systems use only software and readouts from the individual wheel-speed sensors used by the antilock brake system. If all four tires are properly inflated, they will all rotate the same number of revolutions in a stretch of road. If one tire rotates more than the other three, it has a shorter rolling radius because the pressure in it is low.

The indirect type of system is inexpensive, because the only real part that must be added to a car is the display on the dash and some extra code in the vehicle's operating system. Properly inferring tire pressures this way can be a problem when the tires are unevenly worn, or if you replace only two worn tires instead of all four. You can reset the system to allow for wear when all the tire pressures are correct. The procedure varies from vehicle to vehicle, and this one won't necessarily work on yours. Persistent TPMS warnings can often be cured by setting ...
