Abstract: A method for by an asset tracking system is provided. An example method includes receiving a first plurality of data messages from an asset coupled to the asset tracking system and attempting to identify an asset type fingerprint based on the first plurality of messages. In response to failing to identify an asset type fingerprint based on the first plurality of messages, the example method further includes requesting a determined asset type fingerprint for the asset from an asset data analysis system, providing access to the first plurality of data messages to the asset data analysis system, receiving the determined asset type fingerprint for the asset from the asset data analysis system, and obtaining asset information from the asset by decoding a second plurality of data messages received from the asset in accordance with a set of signal definitions linked to the determined asset type fingerprint.

Abstract: Methods for asset type fingerprinting are provided. An example method involves an asset tracking system failing to identify an asset type fingerprint and requesting an asset type fingerprint from an asset data analysis system. The asset data analysis system generates a proposed asset type fingerprint, links the asset type fingerprint to a set of signal definitions that indicate how to decode data messages from the asset. The asset data analysis system transmits the proposed asset type fingerprint to the asset data analysis system, which then decodes at least some data messages from the asset thus obtaining asset information. The method may be used to identify vehicle types and decode proprietary or non-standard data messages via a vehicle's diagnostic port.

Abstract: A method for an asset tracking system is provided. An example method includes receiving data messages from an asset coupled to the asset tracking system and attempting to obtain asset information from data messages with reference to a local set of signal definitions indicating how data messages received from the asset are to be decoded into asset information. Upon failing to obtain the asset information the asset tracking system requests from an asset data analysis system the generation of a generated signal definition indicating how the data message of the outstanding type is to be obtained from the asset. The asset tracking system provides access to at least one undecoded data message of the outstanding data type to the asset data analysis system, receives the generated signal definition from the asset data analysis system, and adds the generated signal definition to the local set of signal definitions.
