Curve approaching mode controller |
摘要 |
<p>A curve approaching mode controller is capable of continuing vehicle control operations for the longest possible time even if curve information is not available from a navigation system. The navigation system provides curve information about a curve on a road stretching ahead of a vehicle. A control unit estimates a curve approaching mode in which the vehicle will approach the curve on the basis of the curve information and, when necessary, gives a warning and executes a decelerating control operation. If only insufficient curve information is available from the navigation system, a road attribute calculating and storing unit stores the normal node information received immediately before receiving the insufficient node information (curve information) without updating the same, and informs a warning speed calculating and storing unit of a fact that the node information is insufficient. A warning speed calculating and storing unit calculates a warning speed that serves as a reference for warning on the basis of the normal node information received immediately before receiving the insufficient node information, taking a distance traveled by the vehicle after the insufficient node information has been received. <IMAGE></p> |
