This paper presents new comfort and convenience features in the luxury segment and focuses especially on Comfort Access and iDrive. The Comfort Access System offers the customer the possibility of unlocking the vehicle without active use of a key, of starting the engine and at the end of the journey of locking the car again. The aim of the iDrive concept was to enable intuitive operation of the various functions with simultaneously improved ergonomics. Both, a monitor and a controller with its variable haptic are the concept’s innovation. In addition, this paper also discusses future ECU (Electronic Control Unit) networks for body electronics. The focus is on package-driven ECU network architecture, having many functions developed by different suppliers on a single ECU.

This paper presents the challenges in automotive electronics. Considering the deficiencies of the current ECU (electronic control unit) design process, a new design process is outlined. This design process mainly focuses on the independence of the ECU hardware architecture development and the software function development.

This paper presents a methodology for tool-assisted development of software for electronic control units in cars. Because of increasing complexity the developer requires a set of tools that cover the whole development process. In this paper the process is separated into several phases. Ideally after analysis there is a specification phase, where executable but hardware independent models are created. After that in the Design phase the hardware architecture is designed and partitioning of the models onto the network of ECUs is performed. Here the appropriate architecture is chosen. This paper shows the seamless methodology from the Specification phase tool ‘ASCET-SD’ to the Design phase tool ‘Virtual Component Co-Design’ (VCC) with respect to the overall design flow. Several ways of doing the transition considering intellectual property protection, target dependency accordingly independency, and model semantics are considered.
