Title:
AUTOMATIC DRIVING ASSISTANCE METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/109516
Kind Code:
A1
Abstract:
The present invention makes it possible for automatic driving to continue while an increase in communication load is minimized under conditions in which a host vehicle approaches a first branch line, which is a non-guided route, and another divergence point is present at a position close to a divergence point of a main line and the first branch line. When there are a main line (101), a first branch line (102), a first divergence point (105), a second divergence point (106), a second branch line (103), and a third branch line (104) set in a first guided route (IC1), and the travel time of a host vehicle (V) from the first divergence point (105) to the second divergence point (106) is less than a required time from the initiation of a process of searching for a second guided route (IC2) by a navigation system to the execution of automatic driving of the host vehicle (V) along the second guided route (IC2) by an automatic driving control device (10), before the host vehicle (V) reaches a prescribed location (107) ahead of the first divergence point (105) along a travel direction, the navigation system executes the process of searching for the second guided route (IC2) and executes a process of outputting the second guided route (IC2) to the automatic driving control device (10).
