Tractor trailer vehicle area network with trailer sub-network

A tractor-trailer vehicle comprising:

• a tractor having at least four tires, at least two of the at least four tires configured to be turned to steer a direction of travel of the tractor;
• a first wireless hub that is integrated with the tractor;
• a trailer that is removably connected to the tractor, the trailer having a front portion that is adapted to connect to the tractor, and a rear portion with at least two tires;
• a second wireless hub that is integrated with the trailer;
• at least one first sensor that is integrated with the tractor;
• at least one second sensor that is integrated with the trailer;
• and
• a telematics module integrated with the trailer;
• wherein:
• the first wireless hub communicates with the second wireless hub by way of WiFi with a first network protocol, thereby establishing a first level of a vehicle area network (VAN) comprising the first wireless hub and the second wireless hub;
• the first wireless hub establishes a first subnetwork in and around the tractor with a network protocol different than the first network protocol, and communicates with the at least one first sensor and the telematics module via the first subnetwork, the first subnetwork being within a second level of the VAN;
• the second wireless hub establishes a second subnetwork in and around the trailer with the network protocol different than the first network protocol, that is separate and distinct from the first subnetwork, and communicates with the at least one second sensor via the second subnetwork, the second subnetwork being within the second level of the VAN;
• and
• processing data from a plurality of sensors of the one or more first sensors to determine proper action for the vehicle, wherein the proper action is selected from the group consisting of:
• displaying a warning on a dashboard in the tractor;
• changing a tire;
• modifying an autonomous control of the vehicle;
• and scheduling a maintenance appointment.
