Towards runtime testing in automotive embedded systems

Exploring the Integration of USART in Automotive Control Systems: Addressing Unexplored Challenges

“…Microcontroller-based architectures, as a cornerstone in automotive control systems, present a cost-effective solution characterized by a single integrated circuit housing a processor core, memory, and dedicated peripherals [11]. While these architectures provide dedicated communication peripherals, streamlining data exchange efficiently, their limitations in processing power may pose challenges, particularly when dealing with complex USART protocols or managing multiple communication channels simultaneously.…”

“…The integration of USART within RTOS-driven automotive systems contributes to efficient and deterministic communication, ensuring that tasks are executed with precision and adherence to strict timing requirements. RTOS, designed explicitly for real-time applications, introduces a layer of predictability and determinism to the execution of tasks in automotive embedded systems [11]. This is particularly essential in safety-critical applications where timely and accurate data transfer is imperative for the overall functionality and reliability of the automotive system.…”

“…This can provide an alternative means of interacting with USART-enabled features, allowing users to command and receive information without taking their eyes off the road. Ensuring the accuracy and responsiveness of these control mechanisms is vital for their successful integration into the overall HMI [11].…”

“…Safety is paramount in automotive design, and the HMI should reflect this priority [11]. USART integration may involve functionalities related to vehicleto-vehicle communication or connectivity with external devices.…”

Finding faults: A scoping study of fault diagnostics for Industrial Cyber–Physical Systems

“…The fault symptoms presented, or Fault Evidence, often include secondary system misbehaviors that are the result of the primary fault but which are not the root cause. Bradatsch et al (2011) defines fault latency as the time between the occurrence of the fault and its recognition by the device's fault management system.…”
