Abstract
Presented are intelligent vehicle communications (comm) systems provisioning enhanced vehicle-to-everything (V2X) wireless mesh network (WMN) hop propagation, methods for making/using such systems, and vehicles equipped with such systems. A method of controlling operation of a host vehicle includes a vehicle controller determining the host vehicle is incapacitated and then detecting the host vehicle's wireless comm device is unable to connect to a cellular or satellite communications system. Responsive to such insufficient connectivity, the controller broadcasts a V2X WMN distress message containing data specific to the host vehicle and data specific to the host vehicle's incapacitating event. Upon receipt of the distress message, a recipient vehicle's controller determines if a prior distress message for the incapacitating vehicle event was previously received and if the distress message exceeds any preset multi-hop restrictions. If yes to either, the resident controller disables retransmission of the distress message to other recipient nodes over the WMN.
