Multi-Connected Cars is Automotive IoT
• The Internet of Things (IoT) extends to the automobile through wireless connections to the ITS infrastructure− Infotainment
Digital Radio, Streaming Video, Connected Games
− Phone service− Internet browser− ADAS (Advanced Driver Assistance
Systems)Lane departure warningCollision avoidanceSign RecognitionRoad geometry trackingParking Assistance
− Vehicle Parameter MonitorsTire PressureBrake wearOil change
• Access to the Cloud helps Integration− But introduces security concerns

The Connected VehicleInfotainment + Communication + Security
• Consumer electronics trends are dictating features in the car
• Always connected, applications driven, advanced graphics
• Infotainment systems becoming battleground for Auto differentiation
• As more connected systems get introduced into the vehicle, theneed for security is critical− Increasing external communication features
(Bluetooth, TPMS, Ethernet, Wi-Fi, etc).
− Future interface for vehicle-to-vehicle and vehicle-to-infrastructure.

Future Trends
• Cross-domain car communicationE.g. increasing safety enabled by data interaction between active safety and advanced driver assistance functions
• Networking of Cars and EnvironmentCar2car communication for efficient organization of traffic flow
• More comfort and safety features in the car− Camera’s, TFT displays, connectivity, functional safety− Example for average car
~40 electric/electronic systems50-100 MCUs>100 sensors
• Memory and performance on the increase− Modern car up to 50Mbyte (excludes infotainment)
TM

Future Trends
• Move to integrate more functions into larger “domain controllers”− Reduce costs, integration complexity and wiring harness weight
• High bandwidth backbone interconnect network needed− Manage the network complexity to reduce the development effort and increase
fault tolerance and robustness of the network− Higher demand on bandwidth and quality of service

The Cloud
• Provides a communication pathway back to the data center
• Enables big data type analytics of data that's broadcast between smart devices and sensors in the vehicle or other road structures
• Opens up the opportunity to inform the driver about local problems and alternatives
• For example sensors installed on a bridge can signal structural or weather related problems such as icing to road side units or directly to the vehicle
• Messaging Protocols− XMPP, MQ/AMQP, MQTT/CoAP− Distributed large scale data traffic
• Data Distribution and Control Protocol− DDS− High Performance – 10uS− Node based publish/subscribe model
