摘要： The present disclosure provides a method and an apparatus for determining positioning information of a vehicle, an electronic device, a storage medium and a computer program product, relating to the field of artificial intelligence, in particular to the field of intelligent driving. The method includes: receiving positioning results and error ranges of the positioning results from at least two positioning subsystems in a vehicle; determining reliability detection results of the positioning results of the positioning subsystems according to the error ranges of the positioning results; and determining positioning information of the vehicle according to a first positioning result of a positioning subsystem whose reliability detection result is “reliable”, and determining an error range of the positioning information, where the error range of the positioning information represents a confidence level of the positioning information.
