Simulation of vehicle braking stability a model integration case study

摘要

TOOLSYS is a joint effort of automotive industry and simulation software suppliers to investigate the capabilities of VHDL-AMS (IEEE 1076.1) as a unified format of multidomain system models. The main goal of TOOLSYS is to facilitate reuse and exchange of models, for example, between a car manufacturer and a component supplier, thus improving the efficiency of product development. An environment for model exchange and simulation, based on three domain specific tools, is proposed and the concepts are evaluated based on several applications. One of the applications consists of a car with an ABS braking system. Preliminary results based on the applications show that VHDL-AMS is useful as a unified model representation but more effort must be spent on modelling methodology and the numerical solvers.
