The invention relates to a networked automobile cooperative sensing
information transmission method, which comprises the following steps of: evaluating the priority of
CAM (
Content Addressable Memory) data packets by adopting an
information value, setting differentiated reference
signal receiving power thresholds for the
CAM data packets with different priorities, and then sending the
CAM data packets to a sending vehicle before the sending vehicle sends the CAM data packets. By re-evaluating the reservation condition of the sub-channel resources in the network, not only can the interference suffered by the high-priority CAM data packets during transmission be reduced, but also the mutual collision among the high-priority CAM data packets can be avoided, the transmission of redundant information is effectively reduced, and when the network of the networked automobile is in a congestion state, the transmission efficiency of the CAM data packets is improved. According to the technical scheme, the
acceptance rate of the CAM data packets with the high priority can be improved to the maximum extent, so that the
utilization rate of the CAM data packets with the high priority is improved, transmission of key information is guaranteed, and cooperative sensing information can be better shared among vehicles.
