Embodiment Construction
[0046] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0047] see figure 1 , is a flow diagram of a real-time precise positioning method for a motor vehicle according to the present invention, including the following steps, S1 motor displacement update, S2 measurement update;
[0048] Wherein the maneuvering displacement update includes the following steps: S101 takes the initial velocity as the initial condition, integrates the inertial acceleration with respect to time to obtain the system inertial rate; S103 takes the initial position coordinates as the initial condition to integrate to obtain the inertial position; repeats the above steps S101, S103 , to obtain a continuous navigation coordinate system; S105 eliminates the deviation between the navigation coordinate system and the vehicl
