Thus, cubiX is an example of a decisive trend on the path towards a software-based vehicle: moving away from the many individual control units of different hardware components, towards cross-functional domain and zone architectures. This development takes account of the increasing complexity of automotive control software. Until now, dampers, brakes or rear axle steering systems each have their own control unit or logic which has to be elaborately integrated into the overall vehicle architecture. The new E/E architectures bundle all software for a specific functional area (the so-called domain) of the car on a central, actuator-independent control unit. "This comprehensive control unit saves manufacturers time and effort as well as compromises in fine tuning and driving dynamics in terms of performance, comfort and efficiency of the vehicle. At the same time, it gives them the opportunity to combine complex assistance systems without any problems," explains cubiX project manager Dr. Caspar Lovell. "With cubiX, we have software that can be perfectly integrated into the new E/E architectures of future vehicles – whether signal-based or service-oriented."
