it seems that there is something wrong with the Coordinate,but Latitude 2764980.037140 is the same with the general info from the command v.info map=‘’‘’‘’.
I wonder it is my problem or the grass?

If I'm not mistaken, kml files need to be in Lat/Lon. WGS84 datum, *not* UTM

On the KML page of OGR it says: "Note that KML by specification uses only a single projection, EPSG:4326" [1]
It also says "As such OGR will create layers in the correct coordinate system and transform any geometries."
Not sure how to interpret this, but from your error message, I would guess that you have to reproject your vector to a epsg:4326 location first, before exporting with v.out.ogr.

Sorry, just reread your message, and my answer is probably not really helpful. In fact v.out.ogr does transform your data to EPSG 4326, as the following message shows:
>> Warning 1: Longitude 638073.992861 has been modified to fit into range
>> [-180,180]. This warning will not be issued any more
No, idea what the ERROR means. What does the resulting KML file look like ?
You still might want to try to reproject (v.proj) to EPSG 4326, just to see what happens.
