Telematics Smart Testing and Validation Tool 2022-28-0092

Connected vehicles has lot of applications coming up which involves Vehicle to Vehicle(V2V), to Infrastructure(V2I) communication techniques and many are getting deployed through frugal connectivity and security solutions. However, executing multiple customer centric, OEM centric and productivity services and applications needs lot of rigorous validation and bulk deployments. This needs lot of time, man efforts, and cost. Also quality of data collected from thousands of vehicles at every few seconds /minutes is matter of concern. There is a desperate need of telematics validation tools which can be customized as per OEM ad-hoc architecture. The suggested telematics smart testing and validation tool involves easy, configurable, and seamless options to test software updates in multiple variable nodes in connected onboard system architecture like telematics ECUs, multiple ECUs (EMS, ACM, IC, and Gateway ECU). The accuracy of the validation is more than 98% considering high sampling frequency of CAN messages on J1939 CAN bus. The system covers overall aspects and gives option to print direct reports to get the insights of the validation software which is under test. This tool does not need any human intervention once installed inside the vehicle and thereby reducing time and man efforts. The data from the telematics device and parallel CAN trans-receiver and connected module is compared and acceptable deviation is configured for quick checks and reports. FTP server is required for data ingress from telematics and ECUs. Tool uses low cost hardware and server to manage data. This tool has potential to have good data quality from vehicles.
