Comprehensive Approach for the Chassis Control Development 2006-01-1280

Handling characteristics, ride comfort and active safety are customer relevant attributes of modern premium vehicles. Electronic control units offer new possibilities to optimize vehicle performance with respect to these goals. The integration of multiple control systems, each with its own focus, leads to a high complexity.
BMW and ITK Engineering have created a tool to tackle this challenge. A simulation environment to cover all development stages has been developed. Various levels of complexity are addressed by a scalable simulation model and functionality, which grows step-by-step with increasing requirements. The simulation environment ensures the coherence of the vehicle data and simulation method for development of the electronic systems.
The article describes both the process of the electronic control unit (ECU) development and positive impact of an integrated tool on the entire vehicle development process. The model structure, model validation, quality assurance, and features of the BMW tool “ISAR” are shown. An ECU system development including the use of a driving simulator and a HiL test bed are given as examples to demonstrate the advantages of this integrated development approach.
