The present disclosure provides a data sharing method, an on-vehicle device, a cloud server, an internet-of-vehicle system, an electronic apparatus, and a computer-readable medium. The data sharing method is applied to the on-vehicle device. The method includes: determining whether there is a sensing blind region around the on-vehicle device based on road condition information acquired by the on-vehicle device in response to a distance between the on-vehicle device and a key road node smaller than a predetermined distance; if there is the sensing blind region around the on-vehicle device, acquiring road condition information of the sensing blind region acquired by an auxiliary equipment; and performing a driving guidance based on the road condition information acquired by the on-vehicle device and the road condition information of the sensing blind region.
