Lecturer: Renato Mandic, Magna-Steyr Fahrzeugtechnik AG & Co. KG
Magna Steyr has been developing electronically controlled all-wheel drive systems for more than a decade. The requirements imposed on such systems with regard to functionality, size, cost and quality are constantly increasing, and the development cost of such systems is also rising.
Taking as an example an integrated transfer case with automated road and offroad gear shifting and a controlled differential lock (ITC), this paper describes the development of an electronic control for these all-wheel drive components. This is a product development that is already far into the production development phase.
The requirements for the electronic control system and the electrical integration of the transfer case into the vehicle are explained, using the system configuration for the ITC transmission as an example.
The functionality of the transfer case is essentially determined by the control software, so this paper describes software development in greater detail.
The entire application software for the production application is performed according to the V-cycle and with systematic use of the Simulink/software-in-the-loop simulation/MicroAutoBox/TargetLink tool chain. Individual steps in this development and the results achieved so far are presented.
