DETAILED DESCRIPTION OF EMBODIMENTS

FIG. 1 is illustrates wireless communication system 100 for a truck 102 and a trailer 104. In this example, a high-speed wireless connector assembly 106 is connected between the truck 102 and the trailer 104 to enable high-speed communication between components of the truck 102 and trailer 104. It should be understood, however, that any vehicles or combination of vehicles may employ features of the embodiments described herein. As used herein, a “vehicle” refers to a thing used for transporting goods and/or people, and may include motorized vehicles, such as trucks, automobiles, and/or motorized construction equipment, and non-motorized vehicles, such as trailers, carts, and/or dollies, for example.

Referring now to FIGS. 2A and 2B, schematic diagram views of the connector assembly 106 of FIG. 1 are illustrated, according to some embodiments. FIG. 2A illustrates the connector assembly 106, including components thereof, in a connected state, and FIG. 2B illustrates the connector assembly 106 in a disconnected state. As noted above, the connector assembly 106 is connected between the truck 102 and the trailer 104. The connector assembly 106 includes a connector assembly housing 108 that houses a first wireless communication module 112 and a second wireless communication module 120. In this example, the first wireless communication module 112 is coupled to electronic circuitry 114 in the truck 102 via a first wired connection 116, and the second wireless communication module 120 is coupled to electronic circuitry 122 in the trailer 104 via a second wired connection 124. The electronic circuitry 114, 122 may be coupled to various components, such as computing devices, sensors, and/or cameras for example.

Forming a direct wired connection between the electronic circuitry 114, 122 in the different vehicles may have a number of disadvantages. One disadvantage is that it may be difficult to disconnect the wired connection to permit the vehicles to be separated from each other or connected to different vehicles. Many high-speed wired connection mechanisms are only capable of a limited number of connection/disconnection cycles without a decrease in the reliability of the high speed wired connection. In this example, instead of forming a direct wired connection, the connector assembly 106 positions the first wireless communication module 112 and a second wireless communication module 120 in close proximity to each other within the connector assembly housing 108. This permits the first wireless communication module 112 and the second wireless communication module 120 to establish a high speed wireless communication link 134 therebetween without the performance degradation that may be exhibited by removable high speed wired connections.

In this embodiment, the first wireless communication module 112 includes a first transceiver 128 connected to a first antenna 126, and the second wireless communication module 120 includes a second transceiver 132 connected to a second antenna 130, but it should be understood that different components may be used, such as dedicated transmitters, receivers, and/or multiple antennas, for example.

In this embodiment, the first antenna 126 of the first wireless communication module 112 and the second antenna 130 of the second wireless communication module 120 are separated within the connector assembly 106 by a distance of less than 5 centimeters, but it should be understood that larger or smaller separation distances may be used, as desired. An advantage of positioning the first wireless communication module 112 and a second wireless communication module 120 in close proximity is that a high speed wireless communication link 134 can be established between the first wireless communication module 112 and the second wireless communication module 120 with a relatively small amount of power. For example, in this example, the first wireless communication module 112 and/or second wireless communication module 120 convert digital data to radio-frequency (RF) waves (e.g., 60 GHz or higher) and vice versa. The RF waves may further include modulation (e.g., quadrature amplitude modulation (QAM), to further increase a bit rate for the wireless communication link 134. For example, in this embodiment, the wireless communication link 134 has a data transfer bandwidth of at least 5 Gigabits per second (Gb/s). In some embodiments, the wireless communication link 134 is 10 Gb/s or more, but it should be understood that the connector assembly 106 may be configured to provide wireless communication links with higher or lower bandwidths, as desired. In some examples, the circuitry 114 in the truck 102 and/or the circuitry 122 in the trailer 104 may include a multiplexer/demultiplexer that combines and/or separates a plurality of individual data signal, from different sensors for example, into a combined high-bandwidth data signal for transmission between the truck 102 and the trailer 104.

Another advantage of this arrangement is that the transmission power for the first wireless communication module 112 and/or the second wireless communication module 120 can be kept relatively low. In addition to reducing power consumption, this also reduces the transmission range of the first wireless communication module 112 and/or the second wireless communication module 120, which in turn makes it more difficult for an unauthorized third party to access the wireless communication link 134.

In this embodiment the connector assembly housing 108 is further configured to fully enclose the first wireless communication module 112 and the second wireless communication module 120 to isolate the first wireless communication module 112 and the second wireless communication module 120 from an environment 138 outside the connector assembly housing 108, such as moisture and other physical hazards. In addition, the connector assembly housing 108 may further include electromagnetic shielding 140 to electromagnetically isolate the first wireless communication module 112 and the second wireless communication module 120 from the environment 138. The electromagnetic shielding 140 provides several benefits. For example, the shielding 140 prevents outside electromagnetic interference with the first wireless communication module 112 and the second wireless communication module 120, which allows the wireless communication link 134 to operate at higher connection speeds more reliably. In addition, the shielding 140 increases security for the wireless communication link 134 by reducing the transmission of electromagnetic signals between the connector assembly housing 108 and the environment 138 in both directions, and avoids regulatory issues that may apply to higher power wireless communication.

In this example, the connection assembly includes a first connector 110 that includes the first wireless communication module 112 and a second connector 118 that includes the second wireless communication module 120. As shown by FIG. 2B, the first connector 110 and the second connector 118 are configured to be selectively mechanically coupled to each other to form the connector assembly 106, and may also be selectively mechanically decoupled from each other, as desired. Because the first wireless communication module 112 and the second wireless communication module 120 do not form a direct wired connection, the number of connection/disconnection cycles for the first connector 110 and the second connector 118 are significantly increased. In this example, the first connector 110 forms a male connection interface 142 and the second connector 118 forms a female connection interface 144, but it should be understood that any number of different connection arrangements and mechanisms may be used, as desired.

In this embodiment, the truck 102 and the trailer 104 are able to move with respect to each other while coupled to each other without disconnecting the connector assembly 106. For example, in the example of FIG. 1, the connector assembly 106 forms a dedicated mechanical tether between the truck 102 and the trailer 104, with a suitable locking mechanism to maintain the connector assembly 106 and wireless communication link 134.

In another example, a mechanical coupling operation of the truck 102 and the trailer 104 may form a suitable connector assembly as part of the coupling operation. In this regard, FIGS. 3A and 3B are views of an alternative mechanical connector assembly 306 in a connected and disconnected state, according to some alternate embodiments. In this example, the truck 102 includes a fifth wheel 346 that couples to a kingpin 348 of the trailer 104 as part of a mechanical coupling operation. In this example, a first connector 310 coupled to the truck 102 near the fifth wheel 346 includes a male connection interface 342 positioned to be received by a female connection interface 344 of a second connector 318 coupled to the trailer 104 near the kingpin 348. In this manner, the mechanical coupling operation between the truck 102 and the trailer 104 forms a connector assembly housing 308, which houses some or all of the components of the connector assembly 106 of FIGS. 1-2B above, or similar components, to provide a wireless communication link between the truck 102 and the trailer 104.

FIG. 4 is a flowchart of operations 400 for a method of wireless communication between a truck and a trailer using a connection assembly, such as the connector assemblies 106, 306 of FIGS. 1-3B for example, according to some embodiments. The operations 400 include connecting a first connector (110) of the truck to a second connector (118) of the trailer (Block 402) to position a first wireless communication module (within a suitable wireless communication distance ( ) of a second wireless communication module. The operations 400 further include establishing a wireless communication link between the first wireless communication module and the second wireless communication module. The operations 400 further include transferring data between the first wireless communication module and the second wireless communication module (Block 406).

In this example, connecting the first connector to the second connector further includes forming a connector assembly housing that fully encloses the first wireless communication module and the second wireless communication module (Block 408). As discussed above, fully enclosing the wireless communication modules may isolate the wireless communication modules from an environment outside the connector assembly housing.
