9. An apparatus for determining positioning information of a vehicle, comprising:
at least one processor, and a memory communicatively connected to the at least one processor;
wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to:
receive positioning results and error ranges of the positioning results from at least two positioning subsystems in a vehicle;
determine reliability detection results of the positioning results of the positioning subsystems according to the error ranges of the positioning results; and
determine positioning information of the vehicle according to a first positioning result of a positioning subsystem whose reliability detection result is “reliable”, and determine an error range of the positioning information, wherein the error range of the positioning information represents a confidence level of the positioning information;
wherein the at least one processor is further enabled to:
in a case that an error range of positioning information obtained last time is within a preset range, compare the error ranges of the positioning results with a first range, wherein the first range is obtained by updating the error range of the positioning information obtained last time; and
if there is an intersection between an error range of a positioning result and the first range, determine that a reliability detection result of the positioning result is “reliable”.
