The invention discloses an abnormal OS independent reset method and system of an intelligent cabin ECU, and the method comprises the steps: detecting state information reported by a Client OS through a periodic thread based on the Host OS after hardware equipment isolation processing of the Host OS and the Client OS is completed, and obtaining a state detection result; when the state detection result is a reset request, reset environment preparation is carried out on the Client OS, and a configuration starting address of a CPU of the Client OS is determined; and performing independent resetting on the Client OS based on the configuration starting address. Hardware equipment of the Host OS and hardware equipment of the Client OS are isolated, the state information reported to the Client OS through the periodic thread is a reset request, and the Host OS is notified to independently reset the current abnormal Client OS, so that the safety of the system is improved.
本发明公开了一种智能座舱ECU的异常OS单独复位方法及系统,所述方法包括:在Host OS和Client OS的硬件设备隔离处理完成后,基于Host OS通过周期线程对Client OS上报的状态信息进行检测,得到状态检测结果;在状态检测结果为复位请求时,对Client OS进行复位环境准备,确定Client OS CPU的配置启动地址;基于配置启动地址对Client OS进行单独复位。而本发明将Host OS和Client OS的硬件设备进行隔离处理,通过周期线程对Client OS上报的状态信息为复位请求,通知Host OS对当前异常Client OS进行单独复位,从而提高了系统的安全性。
