OBJECT-ORIENTED PROGRAMMING TECHNIQUES IN-VEHICLE DYNAMICS SIMULATION

Described in this paper is a novel approach for the object-oriented co mputer modelling of vehicle dynamics. The key feature of the method is to represent the mechanical system as a collection of concatenated tr ansmission elements carrying out component-related tasks autonomously and in a coordinate-free manner. This is accomplished by applying diff erential geometric concepts to the generation of the dynamical equatio ns. The result is a computer library which can be used as a building-b lock system for generating vehicle dynamics simulation programs.
