1. , for determining a method for the health status of the subsystem in Vehicular system, described method comprises:

  • Collect fault signature test findings;

    Operational failure token test result determines the current health state value of subsystem;

    Operational failure token test result determines the current health state value of the multiple parts in subsystem;

    Using Fisrt fault model and the current health state value of subsystem determined by fault signature test findings and the current health state value of parts to determine can not the current health state value of system unit of operational failure token test result;

    Part aging model is used to determine the prediction future health status value of the parts in subsystem;

    Use the future health status value of the second fault model and parts to determine the prediction future health status value of subsystem;

    Determine whether the prediction health status value of subsystem is greater than threshold value;

    AndIf the prediction health status value of subsystem is less than threshold value, so determine the residue useful life longevity of subsystem.
