� AUTOSAR based SW� decoupled SW modules
Conclusion & Outlook
�Within an EC funded research project a central ECU for a BEV wasdeveloped.
� The VHU is at the heart of a novel function architecture based on the use ofdecision units.
� The ECU serves as host for
� drive train control
� vehicle level energy management
� exterioceptive sensors
� HMI
� The demonstrator vehicle is currently being tested!
�We gratefully acknowledge support from the EC under grant no. 258133within the Green Cars Initiative.
