Abstract
An adaptive cruise control system includes a yaw rate sensor for generating a first radius of curvature calculation representing a first projected vehicle path for the automobile, an optical sensor for generating optical sensory data and for generating a second radius of curvature calculation representing a second projected vehicle path for the automobile. A vehicle path calculation module is coupled to receive the first and second radius of curvature calculations and, responsive thereto, to weigh and combine the first and second radius of curvature calculations, and to thereby generate a third radius of curvature calculation representing a third projected vehicle path, and to produce modified yaw rate sensor data therefrom. A vehicle control module is coupled to receive the modified yaw rate sensor data and to control automobile maneuvering functions in response thereto.

11. An adaptive cruise control method for an automobile, comprising the steps of:
-
generating a first radius of curvature calculation representing a first projected vehicle path for the automobile using data from a yaw rate sensor;
generating a second radius of curvature calculation representing a second projected vehicle path for the automobile using vision sensory data from an automobile-equipped optical sensor;
weighing and combining the first and second radius of curvature calculations, and generating therefrom a third radius of curvature calculation representing a third projected vehicle path;
calculating modified yaw rate sensor data using the third radius of curvature calculation; and
controlling automobile maneuvering functions in response to the modified yaw rate sensor data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 19, 20)
