The disclosure provides'coordinating vehicle controller shutdown '. A vehicle includes a first controller that sends a request to enter a lower power mode; and a plurality of second controllers. The second controllers each periodically send a signal to the first controller indicating that operation is in a normal power mode when powered by a primary power converter and, in response to receiving the request, send a signal to the first controller indicating that operation is in a normal power mode when powered by an auxiliary power converter having a smaller maximum power limit than the primary power converter. The signal is not transmitted during the low power mode. Further, the first controller disconnects the first controller and the second controller from the main power converter in response to not receiving the signal for a predetermined period of time.

    本公开提供了“协调车辆控制器关停”。一种车辆包括:第一控制器,所述第一控制器发送进入较低功率模式的请求;和多个第二控制器。所述第二控制器各自在由主功率转换器供电时向所述第一控制器周期性地发送指示操作处于正常功率模式的信号,并且响应于接收到所述请求,在能够由具有比所述主功率转换器小的最大功率限制的辅助功率转换器供电时,在所述低功率模式期间不发送所述信号。此外,所述第一控制器响应于在预定时间段内未接收到所述信号,将所述第一控制器和所述第二控制器与所述主功率转换器断开。
