Abstract: This paper presents the results of a joint venture between the BMW Group (subsequently referred to as BMW) and Robert Bosch GmbH (subsequently referred to as Bosch). The aim of this project was to optimise the development environment of the Dynamic Stability Control (DSC). The basic idea was to shift development activities to the early design phase and to use simulation tools to realise this idea. In the initial stage, the simulation tools from BMW and Bosch had to be merged into a DSC development platform. Bosch contributed the DSC model, the corresponding interface routines and the model of the hydraulic unit for the dynamic brake model. Both models were delivered to BMW to be integrated into, or coupled with, the BMW vehicle model. Modelling knowledge was not revealed since the models from Bosch are non-readable objects or executable codes. The hydraulic unit was integrated into the vehicle model, while the controller (client) and the vehicle model (server) were loosely coupled with the co-simulation method. The subsequent simulation experiments proved the reliability, stability and good performance of this concept. With some modifications, this tool can be easily integrated into the regular development process. In addition, this method can be adapted to other products, if simulation is required in the early development phase, and if the project involves a car manufacturer and a system supplier.

Keywords: simulation tools; co-simulation interface; modelling stability control systems; modelling hydraulic units; devleopment methodology for car manufacturer and supplier.
