Vehicle trailer angle detection system using short range communication devices

A communication system for a vehicle and a trailer, said communication system comprising:

• a first communication device disposed at a trailer;
• a second communication device disposed at a vehicle;
• said first communication device wirelessly transmitting via at least one transmitting antenna a communication to said second communication device, said second communication device receiving via at least one receiving antenna the transmitted communication from said first communication device;
• wherein at least one of (i) said at least one transmitting antenna comprises two spaced apart transmitting antennae and (ii) said at least one receiving antenna comprises two spaced apart receiving antennae;
• and
• wherein, responsive to processing of the transmitted communication received by said second communication device, said communication system determines an angle of the trailer relative to the vehicle.

A communication system for a vehicle and a trailer, said communication system comprising:

• a first communication device disposed at a trailer;
• a second communication device disposed at a vehicle;
• wherein said first and second communication devices comprise first and second dedicated short range communication devices;
• wherein one of said first and second communication devices comprises a pair of spaced apart antennae;
• said first communication device wirelessly transmitting a communication to said second communication device, said second communication device receiving the transmitted communication from said first communication device;
• and
• wherein, responsive to processing of the transmitted communication received by said second communication device, said communication system determines an angle of the trailer relative to the vehicle;
• and
• wherein said communication system is operable to determine the angle of the trailer relative to the vehicle via triangulation based on an antenna of one of said first and second communication devices and spaced apart antennae of the other of said first and second communication devices.
