车载嵌入式系统市场正在朝着嵌入式软件产业化的大幅度提高方向发展。这种演变的技术后果之一是强制性的集成保护机制的嵌入式操作系统内核，以支持多供应商的多关键组件为基础的嵌入式软件的设计。在本文中，我们评估这样的机制：在AUTOSAR OS标准中提出的定时保护机制。该评估表明，目前版本的机制是不完全适应多关键系统，因为它不处理软/非实时应用程序。
The in-vehicle embedded system market is evolving toward a large improvement of the industrialization of the embedded software. One of the technical consequences of this evolution is the mandatory integration of protection mechanisms in the embedded operating system kernels to support the design of multi-suppliers multi-critical component-based embedded software. In this paper, we evaluate such a mechanism: the timing protection mechanism proposed in the AUTOSAR OS standard. This evaluation shows that the present version of the mechanism is not fully adapted to multi-critical systems because it does not handle soft/non real-time applications.
