摘要：

A hierarchical controller for dealing with faults and adverse environmental conditions on an automated highway system (AHS) is proposed. The controller extends a previous control hierarchy designed to work under normal conditions of operation. The faults are classified according to the capabilities remaining on the vehicle or roadside after the fault has occurred. Information about these capabilities is used by supervisors in each of the layers of the hierarchy to select appropriate fault handling strategies. We outline the strategies needed by the supervisors and give examples of their detailed operation. In a companion paper details of communication protocols implementing some of these strategies are presented.
