Automotive Software Self Reprogramming OTA

The automotive industry will have smarter and more advanced technologies than before. Electronic Control Units (ECUs) in vehicles will be more complex due to more interfaces, connections, displays, user demand features, and suppliers. This means there is a great need to supply system updates to improve functionality and fix software bugs.Over-the-Air (OTA) software updates will be highly important for future connected vehicles. The OTA update will enable upgrading the vehicle functionalities or bug fixations in the embedded software installed on its remotely.This paper presents the OTA system architecture that allows vehicles to receive new software versions of their ECUs from the cloud server through GSM and Wi-Fi directly. This architecture depends on the telematics control unit inserted in the vehicle network. It is implemented to prove the concept, tested, and evaluated through this paper.
