Abstract

A system with one or more transceiver antenna assemblies for installation in vehicle side-view mirrors to enable communication with nearby vehicles. Each transceiver antenna assembly may have one or two antenna arrays implemented on a single printed circuit board, protected by an antenna housing used to mount the transceiver antenna inside the mirror assembly. Each antenna array in a dual-channel transceiver antenna may transmit and receive data over one of two DSRC channels. One channel may be used to transmit and receive vehicle data only and the other channel may be used to transmit and receive both vehicle data and audio/video (A/V) data. Each antenna array is connected to a radio in the vehicle that processes received signals and prepares signals for transmission. Such a transceiver antenna system may be especially useful for communication in truck platooning.

Claims

1. A system for communicating between a plurality of trucks, each truck having a cab which, when connected with a trailer in a tractor-trailer configuration, articulates as the truck turns, each cab having two side mirrors, one side mirror being mounted on each side of the cab, the system comprising:

for each cab;

two antennas, each mounted in a respective side mirror of the cab,

and

two antenna housings to mount each of the antennas in the respective side mirror; and

the system further comprising, at each cab;

a radio, connected to the antennas for that cab,

to manage transmission and reception of information transmitted and received via the antennas,

the antennas being mounted within the side mirrors, and the side mirrors being mounted on each cab, so as to maintain, when any of the trucks having the tractor-trailer combination articulates, and when the plurality of trucks are arranged to include a lead truck and a following truck, line-of-sight communication between at least one antenna of the two antennas on the lead truck and at least one antenna of the two antennas on the following truck;

wherein

the antennas are dual-channel antennas, the dual-channel antennas configured to transmit and receive data over both a first channel and a second, different channel; and

each dual-channel antenna comprises a first antenna and a second antenna,

wherein the first antenna and the second antenna are aligned in a collinear direction along a common axis of orientation.

2. The system of claim 1, wherein

the antennas are dual-channel antennas, the dual-channel antennas configured to transmit and receive data over both a first channel and a second, different channel;

and

both channels of each dual-channel antenna carry vehicle data.

3. The system of claim 1, wherein

the antennas are dual-channel antennas, the dual-channel antennas configured to transmit and receive data over both a first channel and a second, different channel;

and

a single channel of each dual-channel antenna carries audio/video data.

4. The system of claim 1, wherein

the antennas are dual-channel antennas, the dual-channel antennas configured to transmit and receive data over both a first channel and a second, different channel;

and

each dual-channel antenna is implemented on a single printed circuit board.

5. The system of claim 1, wherein

the radio operates in a Dedicated Short Range Communications (DSRC) band.

6. A two-way communication method among two or more trucks, each truck having a cab which, when connected with a trailer in a tractor-trailer configuration, articulates as the truck turns, each of the trucks having two side mirrors, one side mirror being mounted on each side of the cab, the method comprising:

communicating information between a pair of said two or more trucks using a dual-channel transceiver antenna mounted in each side mirror of each truck in the pair, the dual-channel transceiver antennas configured to transmit and receive data over both a first channel and a second, different channel while the pair of trucks, in a configuration with a lead truck and a following truck maintain line-of-sight communication between at least one of the dual-channel transceiver antennas on the lead truck and at least one of the dual-channel transceiver antennas of the following truck; and

managing communicated information with a radio in each truck,

the radio connected to the dual-channel transceiver antennas mounted in respective side mirrors of the respective truck to manage transmission and reception of the communicated information transmitted and received via the dual-channel transceiver antennas;

wherein the antennas are dual-channel antennas, the dual-channel antennas configured to transmit and receive data over both a first channel and a second, different channel; and

each dual-channel antenna comprises a first antenna and a second antenna,

wherein the first antenna and the second antenna are aligned in a collinear direction along a common axis of orientation.

7. The method of claim 6, wherein

the radio operates in a Dedicated Short Range Communications (DSRC) band.

8. The method of claim 6, further comprising

communicating vehicle data over both channels of each dual-channel transceiver antenna.

9. The method of claim 6, further comprising

communicating audio/video data over a single channel of each dual-channel transceiver antenna.

10. A rear view assembly for a cab which, when connected with a trailer to form a truck in a tractor-trailer configuration, articulates as the truck turns, each cab having two rear view assemblies, one rear view assembly being mounted on each side of the cab, the rear view assembly comprising:

a casing mounted on a side of the cab;

a viewing device in an adjustable mount attached to the casing and positioned to provide a rear-looking view along the side of the tractor-trailer configuration; and

at least one antenna assembly comprising a dual-channel antenna to transmit and receive radio frequencies, the dual-channel antenna configured to transmit and receive data over a first channel and a second, different channel,

said at least one antenna assembly contained within the casing, and the casing being mounted on the cab, so as to maintain, when the truck having the tractor-trailer configuration articulates, line-of-sight communication between the truck and either a leading truck in a leading tractor-trailer configuration, or a following truck in a following tractor-trailer configuration;

wherein

each dual-channel antenna comprises a first antenna and a second antenna, and

wherein the first antenna and the second antenna are aligned in a collinear direction along a common axis of orientation.

11. The rear view assembly of claim 10, wherein

the casing is fabricated from a material

with an electrical conductivity less than 10 μ

S/m.

12. The rear view assembly of claim 10, wherein

the antenna assembly is not visible from the outside of the rear view assembly.

13. The rear view assembly of claim 10, wherein

the viewing device is a mirror.

14. The rear view assembly of claim 10, wherein

the viewing device is a camera.
