This study presents a detailed review of a contemporary, holistic safety concept for a smart cluster, comprising a multipurpose display and a head unit. The focus is on elucidating the fundamental regulatory requirements for smart clusters within the regulatory frameworks of the United States and the European Union, and drawing connections to the safety requirements and concept of the smart cluster. The paper explores a range of safety mechanisms and architectures designed to actualize these proposed safety requirements. For each mechanism, we provide an in-depth analysis of its benefits and drawbacks, as well as a thorough explanation of its operational logic. This comprehensive evaluation offers valuable insights into developing safer and more efficient smart clusters in line with international regulatory standards.
