1. A map update data processing apparatus, comprising at least one processor and at least one memory, wherein the at least one memory stores program instructions, and the at least one processor is coupled to the at least one memory to execute the instructions to:
obtain, first information from at least one vehicle terminal in a time window;
determine, based on the first information and second information in a map, first change information and precision information and/or confidence information of the first change information, wherein the first change information indicates a difference between the first information and the second information; and
send, the first change information and the precision information and/or the confidence information to a first vehicle terminal; and
wherein the precision information is error information of the first change information, and the error information is a measurement deviation value of the at least one vehicle terminal which is quantized into a plurality of discrete levels.
