Abstract
A vehicle operation support system includes a navigation device, and a drive control device. The navigation device includes: part for storing road information including branch point information; and part for acquiring road curvature information with reference to the road information, and providing the drive control device with the road curvature information, before a vehicle reaches the branch point. The road curvature information includes information about curvature of first and second road sections extending forward from a branch point. The drive control device estimates entrance of the vehicle into one of the first and second road sections as a selected road section, and controls a driving state of the vehicle by operating an actuator with reference to information about curvature of the selected road section, in response to estimation of entrance of the vehicle into the selected road section.
