Development of System Characteristic Optimization Method to Achieve Vehicle Target Performance
Hyundai Motor Company
ABSTRACT
The application of ‘Target Cascading’ in the product development process is well known to be eff ective in various industry
fi elds, and it is a methodology that is already actively applied in various forms in the fi eld of vehicle Ride & Handling
(R&H) performance development. This paper proposes a model-based vehicle performance benchmarking methodology
and a technology for setting system characteristics to achieve handling performance objectives as a means of utilization for
this. Rather than introducing already well-known target deployment techniques, a process is proposed for practical use in
the vehicle development phase through the development of interfaces between low degrees of freedom vehicle model and
optimization software. The methodology presented in this study is expected to be available in a timely manner as a practical
vehicle performance development tool.
