The invention provides a stable clustering routing method based on link perception in a vehicle-mounted self-organizing network, and belongs to the technical field of vehicle-mounted self-organizing networks. The node similarity S, the intimacy IN between nodes and the connectivity D between the nodes in an Affinity Propagation clustering method are utilized for calculating node priority, and the node with the top priority becomes a cluster head; after clustering, according the node link perception method, information disconnection is carried out in a crossing trigger link; a crossing node calculates re-communication probability according to making and breaking of a road segment in last k periods, the crossing node utilizes the re-communication probability and a greedy method for selecting the optimal candidate cluster, and gateway nodes reaching the optimal candidate cluster are selected according to the greedy method. According to the method, the delivery rate of a data package is obviously improved, time delay required by delivery of the data package is reduced, stability of the cluster head is increased, the number of the cluster head is reduced, the hop count and the average delay of data transmission are reduced, and the routing expenses are greatly reduced.
