METHOD FOR DETERMINING A CURRENT POSITION OF A MOTOR VEHICLE IN A GEODETIC COORDINATE SYSTEM AND MOTOR VEHICLE |
摘要 |
Method for determining a current position (5) of a motor vehicle (6) in a geodetic coordinate system from a time series of first geodetic position data (2) recorded particularly by a position sensor (8) associated with a global navigation satellite system, and proper motion data (3) recorded by at least one proper motion sensor (9), wherein the position is determined by applying a transformation into the geodetic coordinate system to the displacement vector of the motor vehicle (6), which is derived from the most current proper motion data (3) starting from a reference time to which the transformation relates, wherein the transformation is determined in the context of a regression analysis as optimal mapping of a progression of displacement vectors determined over a defined time period onto a progression of the position data (2) determined for the same time period. |

1. Method for determining a current position (5) of a motor vehicle (6) in a geodetic coordinate system from a time series of first geodetic position data (2) recorded particularly by a position sensor (8) associated with a global navigation satellite system, and proper motion data (3) recorded by at least one proper motion sensor (9),
characterized in that the position is determined by applying a transformation into the geodetic coordinate system to the displacement vector (3) of the motor vehicle (6) which is derived from the most current proper motion data starting from a reference time to which the transformation relates, wherein the transformation is determined in the context of a regression analysis as optimal mapping of a progression of displacement vectors determined over a defined time period onto a progression of the position data (2) determined for the same time period. |
