Abstract
An active suspension system for a vehicle including elements for developing and executing a trajectory plan responsive to the path on which the vehicle is traveling. The system may include a location system for locating the vehicle, and a system for retrieving a road profile corresponding to the vehicle location.
Claims8
A method for improving accuracy of vehicle position determination, comprising:
- determining an initial vehicle position estimate based on GPS data,
- recording a sequence of sensor data from a sensor located with the vehicle, and
- refining the initial vehicle position estimate by performing pattern matching with a pattern matching system that looks for the presence of a known sequence of data in the recorded sequence of sensor data
- wherein the pattern matching system multiplies a sequence consisting of n numbers obtained from the known sequence of data by a corresponding sequence of n numbers obtained from the recorded sequence of sensor data, sums the results of the n multiplications, and determines when the sequences match by identifying when the sum of the n multiplications has a peak.
