    • A vehicle communication system including a master ECU and multiple slave ECUs is disclosed. Each slave ECU initializes its storage medium if an abnormality occurs in the storage medium, and transmits a stored vehicle common information element. Some of the multiple slave ECUs are volatile memory slave ECUs in which the storage medium is a volatile memory. If the master ECU receives the common information elements from all of the volatile memory slave ECUs, and if at least one but not all of the received common information elements has an initialized initial value, the master ECU determines that a memory abnormality has occurred in the storage medium of the volatile memory slave ECU in which the common information element has the initialized initial value.
    • 公开了一种包括主ECU和多个从ECU的车辆通信系统。 如果在存储介质中发生异常,则每个从ECU初始化其存储介质,并发送存储的车辆公共信息元素。 多个从ECU中的一些是易失性存储器从属ECU,其中存储介质是易失性存储器。 如果主ECU从所有易失性存储器从ECU接收到公共信息元素,并且如果所接收到的公共信息元素中的至少一个但不是全部具有初始化的初始值,则主ECU确定在 其中公共信息元素具有初始化初始值的易失性存储器从ECU的存储介质。
