UNKNOWN ON-BOARD DIAGNOSTICS (OBD) PROTOCOL INTERPRETER AND CONVERSION SYSTEM

摘要

A novel on-board diagnostics (OBD) protocol interpreter and conversion system is capable of dynamically decoding commonly-known standard OBD formats as well as esoterically-customized and/or non-standard OBD formats that are initially unrecognized by a generic OBD data reader unit. The novel OBD protocol interpreter and conversion system includes an OBD protocol converter (OPC) unit that can be plugged to a vehicle OBD unit for seamlessly converting any types of standard and non-standard OBD formats to an OBD format compatible for real-time remote vehicle monitoring. For the esoterically-customized and/or non-standard OBD formats that cannot be decoded within the OPC alone, an unknown OBD protocol analysis module and a new OBD protocol interpreter development unit that are located remotely outside the vehicle can create installable new OBD interpreter codes, and update the OPC's OBD library and decoding units accordingly to enable seamless decoding of the esoterically-customized and/or non-standard OBD formats.

主权项

1. An unknown on-board diagnostics (OBD) protocol interpreter and conversion system for remote vehicle OBD monitoring, the unknown OBD protocol interpreter and conversion system comprising:
a vehicle on-board diagnostics (OBD) unit connected to an engine control unit or a vehicular control chipset of a vehicle to record, diagnose, and generate vehicle speed data, acceleration and deceleration data, ambient air temperature data, and other vehicle diagnostics data as a raw OBD data stream; an on-board diagnostics (OBD) protocol converter unit connected to the vehicle on-board diagnostics unit, wherein the on-board diagnostics protocol converter unit is configured to decode an unknown OBD protocol to an OBD protocol library as well as a known OBD protocol to the OBD protocol library, wherein the unknown OBD protocol is correctly decoded by saving the raw OBD data stream, transmitting the raw OBD data stream and a request for analysis of the unknown OBD protocol to a remote monitoring station located remotely outside of the vehicle, receiving installable new OBD interpreter codes from a new OBD interpreter development unit, which is a machine-learning module with artificial intelligence in the remote monitoring station, and interpreting the unknown OBD protocol with the installable new OBD interpreter codes updated in the on-board diagnostics protocol converter unit; an on-board data transceiver unit connected to the on-board diagnostics protocol converter unit, wherein the on-board data transceiver unit is configured to transmit information to or receive the information from the new OBD interpreter development unit via a data communication network; and the data communication network configured to provide a wireless data information transfer between the OBD data transceiver unit and the on-board diagnostics protocol converter unit.
