1. A method for associating a trailer sensor with a vehicle comprising:
- transmitting a first synchronizing signal to a processor in response to a synchronization event;
transmitting a first trailer sensor message from a measurement device operably associated with the trailer sensor to the processor in response to the synchronization event;
establishing an association between the trailer sensor and the vehicle by determining whether the first trailer sensor message was received by the processor within a predetermined period of time after the synchronizing signal was received by the processor;
designating the trailer sensor as valid when the first trailer sensor message is received by the processor within the predetermined period of time, and invalid when the first trailer sensor message is received by the processor after the predetermined period of time has expired; and
designating as valid a trailer sensor message transmitted from a measurement device operably associated with a valid trailer sensor and received by the processor after expiration of the predetermined period of time.

Abstract
A system and method for associating a vehicle and vehicle trailer is described. The system comprises one or more sensors that transmit information wirelessly to a tractor display unit. The tractor display unit determines whether the sensor is associated with a trailer to which it is connected and filters out messages from sensors that are not associated with its trailer. To determine which sensors are associated with its trailer, a processor in the tractor display unit synchronizes the reception of sensor messages with the reception of a synchronizing signal, such as a signal generated by operating an auxiliary power system, turn signal, or brake.

21. A method for establishing an association between a trailer measurement device attached to a trailer and a vehicle used to transport the trailer, the method comprising:
-
operating a vehicle control to generate a control signal and a synchronizing signal; transmitting the control signal from the vehicle to the trailer, the control signal configured to cause a trailer measurement device located on the trailer to transmit a synchronizing message to a processor; transmitting the synchronizing signal to the processor; transmitting the synchronizing message from the trailer measurement device to the processor in response to the control signal transmitted from the vehicle control to the trailer; establishing an association between the vehicle and the trailer measurement device by determining whether the trailer synchronizing message was received by the processor within a predetermined period of time after the synchronizing signal was received by the processor; and designating the trailer measurement device as valid when the trailer synchronizing message is received by the processor within the predetermined period of time, and invalid when the trailer synchronizing message is received by the processor after the predetermined period of time has expired. - View Dependent Claims (22, 23, 24, 25)
