IoT-based Software Update Proposal for Next Generation Automotive Middleware Stacks

Automotive software in modern vehicles is becoming very complex and various new features and opportunities are offered. Main problem for manufacturers is to ensure that new features, bug fixes and improvements are quickly applied to vehicles, as today's methods of software updates in repair shops are unpractical. Over-the-Air (OTA) updates as a faster way of suppling new software without driver interruption are considered instead. This requires the development of a platform with possibility of dynamic deployment and update of applications which is Adaptive AUTOSAR. These procedures shall not violate proper work of safety critical ECUs, and shall keep the system safe from external intrusions. In this paper, we present a solution for vehicle update that includes integration of IoT technologies with Adaptive AUTOSAR platform, usage of access policies, and installation flow.
