  • Abstract:
    The check-out process is a critical component for ensuring AHS safety. It concerns the process of assuring safe transfer of control from the automated driving system to manual driving. Because the driver has been out of the driving loop during AHS operation, there is concern that the driver will not be ready or capable of assuming driving control and responsibility. Check-out is the procedure for transferring vehicle control to manual operation in a way that ensures driver readiness and capability, and tests the integrity of mechanical vehicle components needed for manual driving. The objective of this task is to identify and analyze issues associated with the design and implementation of a check-out process, within the context and structure of the AHS representative system configurations. In order to complete this task, we have applied engineering analyses and small group brainstorming as the primary technical approaches. In addition, we have conducted a literature review, and have obtained inputs from other PSA tasks, as necessary. Our analysis has identified two distinct forms of the check-out process. The first, normal check-out, occurs at the end of an AHS trip. It is a routine process used to evaluate the driver’s ability to retake manual control, when he/she has indicated a desire to exit the AHS. The second, emergency check-out, occurs during an automated trip, when a malfunction in the system is detected, requiring driver intervention. This type of check-out usually occurs with little forewarning.
