Automotive connectivity has come a long way since its humble beginnings of simple interconnects between control modules to multi-node high-speed interfaces such as CANBUS, FlexRay and even common Ethernet. On the horizon we see completely autonomous vehicles and increased IoT services. The main driving force behind this rapid development is the addition of numerous interconnected telematics and internet connected services, such as Spotify, accessing the content via WiFi, 4G, and soon 5G cellular networks.
Not even the once mystical OBDII (On Board Diagnostics 2) interface is safe, with Bluetooth and Wi-Fi dongles allowing the general public to identify faults on their vehicle, reset error codes and even log operational parameters such as engine RPM and speed. In addition, back-end systems within the OEMs organisations, such as Tesla, can remotely communicate with vehicles pushing out firmware updates as and when required.
