Patent attributes
The present invention relates to a method and device for navigating an autonomous vehicle. The autonomous vehicle generates a first trajectory based on a path of navigation and determines a current velocity and present load of the autonomous vehicle. Further, the autonomous vehicle measures a curvature of a curved segment in the first trajectory and matches the measured curvature of the curved segment with a plurality of curvatures of a second trajectory from a trajectory performance profile of the autonomous vehicle. The second trajectory is obtained by applying a plurality of linear and angular velocities to the autonomous vehicle on a test track. Further, the autonomous vehicle selects an optimal trajectory from the trajectory performance profile based on the matching and the current velocity and the present load of the autonomous vehicle. Further, the autonomous vehicle navigates along the optimal trajectory.
