Trailer sensor module and associated method of wireless trailer identification and motion estimation

摘要

A method of identifying a trailer with a vehicle includes a step of transmitting a unique identifier with a wireless transmitter attached to the trailer. The wireless transmitter may be housed as part of a sensor module with a sensor that senses a parameter of the trailer for operating a trailer backup assist system. The housing of the sensor module may be adapted to be removably attached to the trailer. The unique identifier emitted by the wireless transmitter is received with a wireless receiver on the vehicle. After the unique identifier is recognized by a controller on the vehicle, a parameter of the trailer may be accessed for autonomously guiding the trailer along a desired backing path.

1. A method of identifying a trailer with a vehicle, comprising:
transmitting a unique identifier with a wireless transmitter attached to the trailer; receiving the unique identifier with a wireless receiver on the vehicle; determining that the trailer associated with the unique identifier is coupled with a hitch of the vehicle based on the wireless receiver consistently receiving signals from the wireless transmitter; and accessing a parameter of the trailer based on the received unique identifier for autonomously guiding the trailer along a desired backing path.
