Core Viewpoint - The article discusses the transition of automotive electronics from a "multi-ECU distributed" architecture to a "centralized" one, highlighting the benefits of reduced hardware and concentrated resources, while also addressing the risks of potential interference between functions of different safety levels on the same computing platform [8][9]. Group 1: Background and Objectives - The shift to centralized architecture increases the risk of "safety crosstalk," where one function may inadvertently alter another's data, potentially leading to malfunctions [9]. - The goal of the intelligent vehicle control OS is to establish clear spatial and permission boundaries for integrated functions, ensuring stable coexistence of different safety levels on the same platform [10]. Group 2: Key Features of the Isolation Framework - The intelligent vehicle control OS introduces a lightweight safety isolation framework that emphasizes three main features: hard isolation, low overhead, and fast recovery [10]. - Hard isolation involves a multi-dimensional memory mapping and fine-grained isolation mechanism that utilizes hardware Memory Protection Units (MPU) to protect application tasks and data [12][25]. - Low overhead is achieved through a lightweight synchronous remote call mechanism that decouples memory access domain switching from task scheduling, allowing for efficient inter-application communication with minimal latency [15][18]. - Fast recovery is facilitated by a fault detection and recovery mechanism that allows for independent reset of isolated units without affecting other applications, thus maintaining system stability [19][30]. Group 3: Technical Solutions - The lightweight software decoupling framework supports spatial isolation mechanisms across cores, system software, and application layers, balancing safety and resource efficiency [22][24]. - The multi-dimensional layered memory mapping allows for precise data allocation and classification based on ownership, functionality, and software hierarchy [25][27]. - The high-performance communication mechanism ensures that calls between isolated functional units maintain task context and minimize resource consumption [28][30]. Group 4: Practical Implementation - The article mentions practical demonstrations using TC397 or E3650 development boards, showcasing the collaborative effects of hard isolation, low overhead communication, and fast recovery in real deployment scenarios [37]. - The recovery process involves a series of steps from fault detection to resource cleanup and application restart, ensuring that unaffected applications continue to operate normally [38]. Group 5: Conclusion - The intelligent vehicle control OS effectively addresses the challenges of crosstalk and real-time performance in centralized vehicle control by implementing a lightweight safety isolation framework, achieving a balance between safety and efficiency [40].
