The U.S. NHTSA has established the FMVSS 126 standard that requires all vehicles sold in the U.S. to include an ESC system as standard equipment after September 1 st , 2011. There is growing concern among aftermarket suppliers specialized in development and installation of vehicle performance parts that chassis modifications may cause the ESC systems to be inoperative or can create unforeseen issues with stability and safety systems. This industry is in need of a process to support the development and validation of chassis modification. The authors propose the implementation of SIL and HIL simulations as a solution to the problem statement. Based on the results of a sensitivity analysis, guidelines for safe aftermarket modifications will be presented.

Traditionally new technologies are delivered into the automotive industry through the aftermarket. The shorter development cycle of an aftermarket product, which can be less than half of an equivalent OEM part, is the primary enabler of earlier introduction.Aftermarket development lead-times can be less than one year. However, an OEM electronic device will typically be subjected to rigid bench and in-vehicle testing that contribute to a development time of over two years.This article will explore some of these development cycle differences and the challenges in delivering new technologies to the OEM market.

TOkaido Shinkansen track MAintenance system (TOSMA) has been developed so as to realize the system which makes the plan for track maintenance not only fully using the data held in new "Permanent Way Management System" but also changing the track management from that controlling the size of irregularity to that controlling the irregularity growth. The TOSMA gives the final converged size of irregularity in each lot of 20 m long, that in the section of several hundreds meters and that in the district of several kilometers. The amelioration of the lot with extreme growth makes the exclusion of manual maintenance possible.

Aftermarket Service Information: Problems and Solutions in the 1990s

The worldwide automotive service industry is facing a number of challenges in the 1990s. This paper is concerned specifically with the cost of providing adequate service information on modern vehicles, and some suggested ways for automakers, publishers and repair shops to cope with those costs. The examples in this paper deal specifically with the repair information industry that exists in North America, although similar developments have occurred or may occur in other countries.

Hailed as a revolutionary advance that will drastically reduce truck fleet maintenance costs while increasing efficiency and productivity is the new ATA-developed maintenance reporting system. Designed for use by both fleet users and vehicle and component manufacturers, the system has great flexibility and for the first time provides uniform definitions and methods of reporting as well as a common nomenclature language. Practical, comprehensive and capable of extension to meet foreseeable needs of the trucking industry, the system may well be the catalyst to bring about development of the truck of tomorrow~the true 500,000-mile, minimum-maintenance chassis. When widely adopted, it is sure to result in safer vehicles whose lifetime maintenance expenses will be minimal while their productivity and resale values exceed anything now known.
