Method and system for associating a vehicle trailer to a vehicle

摘要

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.

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.
