  "textContent": "A method for estimating positioning precision error and apparatus, a device and a storage medium, applied in the fields of maps, navigation, automatic driving, Internet of Vehicles, intelligent transportation, cloud computing, etc. The method for estimating positioning precision error comprises: acquiring first driving information of a vehicle collected by a sensor(510); according to the first driving information, obtaining first position information of the vehicle, and a first intermediate variable used in the process of determining the first position information(520); according to the first driving information and the first intermediate variable, determining a target precision estimation model among pre-trained precision estimation models (530); inputting the first position information and the first intermediate variable into the target precision estimation model to obtain second position information of the vehicle, and a precision error of the first position information relative to the second position information(540). The precision error of high-precision positioning can be effectively evaluated.",
