Summary:

With the introduction of Connected vehicles, it is possible to extend the limited horizon ofvehicles on the road by collective perceptions, where vehicles periodically share their information with others vehicles / servers using cloud. Nevertheless, by the time the connected vehicle spread expands, it is critical to understand the validation techniques which can be used to ensure a flawless transfer of data and connectivity. Usually the connected vehicle validation is limited to Application layer only in most of the OEMs. However in this work, we focus on validation of all the 4 layers involved namely, Physical hardware layer, Communication layer, Cloud platform and Application layer. For physical and communication layer, we simulated the in-vehicle environment using standalone vehicle electronic control units (ECUs) which communicate with the telematics control unit (TCU) available in the vehicle and a localized load box for replicating the actual load cases. By applying various use cases and simulations using a GPS simulator, along with connection to cloud server, complete stream of data being sent by TCU to the cloud was assessed for correctness. For the Cloud platform and Application layer, varied factors were tested such as response time, compatibility, handshaking, data security et cetera to ensure smooth flow of data and a flawless experience to the customer using the mobile app. On the other hand, there are certain parameters which require actual vehicle level validation where the telematics performance depends upon the real time environmental factors such as different weather scenarios, tunnel / basement related topography and mountainous terrain. It is insufficient to overcome this problem by increasing the antenna sensitivity as that doesn't imply the actual use case scenario for such conditions. Our analysis also shows that connectivity of a connected vehicle hugely depends upon the advanced driver assistance system sensors and other peripheral ECUs in a vehicle such as instrument cluster, infotainment head unit, engine management system and passive entry passive start ECU
