A system includes data processing hardware and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to perform operations. The operations include configuring a ping interval protocol for an electronic control unit (ECU), initializing a ping fail counter of the ping interval protocol, and establishing a message queueing telemetry transport (MQTT) session. The operations also include detecting a ping status of the ping interval protocol, determining, automatically, an optimal ping interval of the ping interval protocol based on the detected ping status and the ping fail counter, constructing a ping interval topic for the MQTT session, and publishing the determined optimal ping interval to the ping interval topic.

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.

Presented are intelligent vehicle communications systems for cellular link monitoring and failure detection, methods for making/using such systems, and vehicles equipped with such systems. A method for operating a wireless-enabled vehicle component of a motor vehicle includes a cellular communications device of the vehicle component detecting an uplink (or downlink) network data packet transmitted by (or to) the vehicle. An electronic vehicle controller then establishes an observation period as a function of the time at which the network data packet was transmitted. The opposite downlink (or uplink) of the wireless-enabled vehicle component is monitored to determine if a downlink (or uplink) network data packet is received within the observation period, thereby indicating detection of a cellular link failure. Responsive to a detected cellular link failure, the vehicle controller conducts a supplemental assessment of the opposite link and/or a corrective action to re-establish a data link for the opposite link.
