Abstract
To eliminate any mis-learning of a sensor code in a factory environment due to adjacent vehicles, a vehicle ID is sent to a sensor transmitter by an initiation signal. When the sensor transmitter transmits its sensor identification signal to the vehicle control in a “learn” mode, the vehicle ID received in the initiation signal is carried with a combined signal. The vehicle control receives the combined signal, and if the received vehicle identification code in the signal matches an expected vehicle identification code, then the control learns the sensor identification. If the expected vehicle identification code does not match the received vehicle identification code, then the control may ignore the particular sensor identification code. This invention thus eliminates any tendency to have an adjacent vehicle inadvertently “teach” its sensor IDs to the control associated with the adjacent vehicle.
