Because the use of software in automotive industries is growing constantly as vehicles are rapidly getting more complicated to adopt advanced technologies and supplementary functions, the quality of software has been a critical factor for the quality of automotive parts, and the vehicle also. But owing to the nature of software, the software quality assurance system should be different from that of hardware, and usually based on the quality models like ISO-9001, CMMI, or SPICE, which was developed for software. We have developed the CMM Level2 based standard software process, MSDP consists of planning, requirements management, process tracking, quality assurance and so on and implemented it to development, testing, and maintenance of chassis control systems like ESP, CDC, MOPS and others. We could reduce much more defects in the earlier development phase than before by complying the newly made standard process and auditing the software related activities with quality assurance system. Furthermore, we are continuously revising the standard process to be more effective for quality control and to be CMMI Level3 compliant.

Recently automotive company demands supplier to provide goods as a module unit, Automotive company presents some requirements for a modular assembly and supplier delivers modules satisfying those requirements. This trend requires the development of methods to predict the performance of modules in the vehicle environment. The development of assembled analytical models that reflect the interactions between components within a modular assembly is necessary to insure that a module is properly designed. This paper describes the construction of the finite element model to investigate the structural requirements for Damper Spring Module(DSM) as installed in a McPherson strut front suspension. The analytical model is constructed as the 1/4 car. The modeling techniques to construct the components within DSM are presented. Results of the structural analysis under some loading conditions are displayed. Additionally, some aspects to be observed in the assembly model are considered.

In this paper we propose an Active Height Control system which consists of an automatic air leveling and semiactive suspension system for an SUV (sport utility vehicle). Prior to a real car installation to estimate the vehicle performance and tune the control logic, we model the vehicle with flexible body frame and AHC system using ADAMS. We analyzed the vehicle handling performance for various driving conditions by simulation. Then we apply the AHC system to an SUV and tested its performances.
