Next Generation Scalable Architecture 3

What do you expect from a smart vehicle?

?• Additional features

• Support cross domain functions

• Increased application diversity for different vehicle configuration and different models

• Individualization – different features and setups on vehicles with the same hardware

• Personalization – available features and setups are linked to an individual driver account

• Upgradability – new functionality can be installed over time

CAN, CAN-FD and Lin Networks are not shown in this picture

• Centralization of vehicle functionality in a few powerful ECUs called ICAS (In Car Application Server)

• Connecting sensors and actuators using powerful network technology such asEthernet and CAN-FD to the central ECU

• Consolidation of many different functionalities in powerful ECUs using virtualization

Benefits:

• Complexity of centralized implementation is lower compared to distributed functionalities

• No functional dependencies between sensor/actuator ECUs

• Separation of sensor/actuator and advanced vehicle functionalities increases flexibility for adding new features (feature update)

New requirements:

• High performance microprocessors

• Powerful OS Linux + Adaptive AUTOSAR

• High speed networking

Impact on Network Bandwidth

• The new E/E architecture is an enabler for a large number of new functionalities

• Most of the new functions are implemented in the ICAS ECUs

• Features like WiFi and LTE connectivity increases the bandwidth as well as Ethernet-based camera systems and other ADAS Sensors

On some links there is a bandwidth >> 100Mbit/s needed

Solution: Investigate 1000BASE-T1 for these links

~800Mbit/s


Qualifying 1000BASE-T1 for use at VW
