Ride comfort performance of commercial vehicle is one of the key factors for increasing its attractiveness, however because of increasingly complex systems, components and units, also the increasing vehicle weight due to vehicle electrification and intelligent driving systems, development becomes an increasing challenge and one that needs to be addressed up-front in the development cycle. In order to improve the comfort performance, it is important to consider not only general Ride Comfort (Primary/Secondary: up to 25z) but also Harshness(25-150Hz). To reduce the development costs which are caused by tougher requirements and enlarged performance scope, Model Based Design (MBD) techniques are increasing applied at an early development phase of the design. Application of their method in vehicle manufacturers has been conducted on ride comfort performance [1]. However, the scope in almost of all cases is only Primary/ Secondary ride.

    In this research, a hybrid system simulation model which can consider the full performance scope in early vehicle development phase, has been built and applied for vehicle evaluation. It is possible to consider high frequency phenomena that be contributed to Harshness by including a detailed suspension model, body transfer function (from Test or 3D-CAE result) as its characteristics. This model’s effectiveness has been validated for performance study on early development phase. This paper shows the hybrid system simulation model building methodology and the result of a comparison between vehicle test and this model.
