Vehicular GPS/DR Navigation with Environmental-Adaptive Kalman Filter Gain |
| 摘要 |
A method is provided for estimating position using an integrated Global Navigation Satellite System (GNSS)/dead reckoning (DR) (GNSS/DR) navigation system in a vehicle. The method includes: determining a current environment of the vehicle from a plurality of environments based on at least one parameter; calculating a Kalman filter-related parameter based on the determined current environment, wherein the Kalman filter-related parameter corresponds to a representation of weight given to GNSS navigation and DR navigation relative to one another; and estimating a position of the vehicle based on the calculated Kalman filter-related parameter utilizing a Kalman filter. |
