关于轿厢意外移动保护系统检测电路的探讨

摘要

首先简要介绍轿厢意外移动保护装置（UCMP）的定义以及相关标准的技术要求，接着通过分析一种常见的UCMP检测电路，指出该电路存在的缺陷，最后提出观点，即：UCMP检测电路为含电子元件的安全电路时，传感器（感应开关）应是安全电路的一部分，并应满足安全电路风险评价要求。%The definition and relative standards requirement for Unintended Car Movement Protection (UCMP)are introduced in this paper, an typical detection circuit for UCMP is analyzed, the design flaws for this circuit are pointed out, some design criterions are proposed : the sensor shall be designed as one part of the safety circuit for UCMP detection circuit and shall be met the risk evaluation requirement of safety circuit when UCMP detection circuit is electrical component safety circuit.
