However, Apple states that providing interfaces for such guidance that is intuitive and easy to use, especially in environments such as parking lots where detailed and / or accurate map data may not be available, may present a non-trivial challenge. But the company thinks it's up to the job.
Here is the summary of the invention: "Signals that can be used to determine a vehicle's trajectory toward a particular stop near a destination are discovered by a person authorized to provide guidance with respect to the vehicle's movements. at least in part on the signals and a data set relating to the vehicle's external environment, one or more vehicle movements to be implemented to continue along the track are identified. A directive is transferred to a motion control subsystem of the vehicle to initiate one of the vehicle movements. "
