Vehicle Operation Support System and Navigation Apparatus
First Claim
1. A vehicle operation support system for a vehicle, comprising:
- a navigation device; and
a drive control device configured to control with an actuator a driving state of the vehicle,wherein;
the navigation device includes;
a map data storage part configured to store road information, wherein the road information includes branch point information; and
a road information acquiring part configured to;
acquire road curvature information with reference to the road information, wherein the road curvature information includes at least;
information about curvature of a first road section extending forward from a branch point; and
information about curvature of a second road section extending forward from the branch point; and
provide the drive control device with the road curvature information, before the vehicle reaches the branch point;
the drive control device includes a road selection estimation part configured to estimate entrance of the vehicle into one of the first and second road sections as a selected road section; and
the drive control device is further configured to control the driving state of the vehicle by operating the actuator with reference to the information about curvature of the selected road section, in response to estimation of entrance of the vehicle into the selected road section.

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.
