The present invention relates generally to the communication of vehicle data, diagnostics and related information with a network remote from the vehicle, and more particularly to communications and storage of vehicle data in the cloud.
On Board Diagnostic (OBD) systems provide a method for vehicles to self-diagnose and report on the diagnosis through readers that are compatible with the OBD protocol. Early OBD systems often illuminated a light or switch to visual report an incident requiring attention or correction. In 1996, the OBD-II standard (an improvement over the original OBD) was mandated as being a required approach and capability for all automobiles sold within the United States.
The OBD-II standard provides for a specific diagnostic connector with pins of a particular orientation (i.e., a standard hardware interface), specific availability of certain electrical signaling protocols (i.e., communication protocols), and a particular messaging format (i.e., report out).
Some of the information about the vehicle that is available for display includes vehicle parameters and data from the engine control unit (ECU) and offers an information inside a vehicle, typically in an encoded format. Vehicle parameters that provide information about emissions, oxygen sensor status and conditions, cylinder operations, etc., are some examples. Many vehicle manufacturers have enabled the OBD-II Data Link Connector to be the primary connector in the vehicle through which many systems are diagnosed and programmed. Information concerning such systems is provided for as OBD-II Diagnostic Trouble Codes (DTCs) and are typically 4-digits with an alphabetic prefix of: P for engine and transmission (powertrain), B for body, C for chassis, and U for network. When properly connected and powered, the reader is able to decode the encoded vehicle data for the specific vehicle being evaluated and a diagnosis of vehicle systems and functions can be determined based on received codes.
OBD-II can interface with multiple communication protocols deployed inside a vehicle. There are five protocols used in the OBD-II vehicle diagnostics standard: (1) Society of Automotive Engineers (SAE) J1850 pulse-width modulation (PWM)—a standard of the Ford Motor Company; (2) SAE J1850 variable pulse width (VPW)—a standard of General Motors; (3) International Organization for Standardization (ISO) 9141-2, which is primarily used in Chrysler, European, and Asia vehicles; (4) ISO 14230 Keyword Protocol 2000 (KWP2000); and (5) ISO 15765 Controller Area Network (CAN) bus, where vehicles sold in the US are required to implement CAN as one of their signaling protocols as of 2008.
OBD II has proven to be a standard having widespread utilization in the automobile industry and more recently in adjacent industrial and medical-related markets. However, the application of utilization of OBD II remains limited to localized methods of display and communications. For instance, the tethered communication arrangement of
However, what is desired is the ability to extract vehicle diagnostics and related information from vehicles and equipment using one or more existing OBD II communications protocols while being able to link and store the acquired diagnostic and information in the cloud, via cloud computing, for further utilization.

The present invention relates generally to the communication of vehicle data, diagnostics and related information with a network remote from the vehicle, and more particularly to communications and storage of vehicle data in the cloud.
The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein.
From
In one or more preferred embodiments, the device controller also provides support for controlling vehicle diagnostics and reporting from the SBS. Preferably, the controller communicates using a unique protocol to communicate with the SBS Broker component 260 (discussed later and also as a communication server) although the unique protocol is not essential to the present invention. Communication between the DPS and the SBS, across a network 249, is typically handled through the communication linkage between DPS' device controller 230, the device communication module 240, and the SBS' Broker 260, where the communication linkage can be over a variety of communication architectures, methods, and networks, including but not limited to: Code division multiple access (CDMA), Global System for Mobile Communications (GSM) (“GSM” is a trademark of the GSM Association), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), 4G LTE, wireless local area network (WIFI), and one or more wired networks. Messages containing information related to commands, vehicle data, service data and proprietary data are passed between the DPS and the SBS across networks 249.
The DPS' device controller, in one or more preferred embodiments may be a circuit board, a control device, software, firmware, or an Arduino board that interfaces with the DPS communication module.
In one or more preferred embodiments, the device communication module 240 provides for transmitting vehicle data over a remote network 251 to the SBS 250. Preferably, the module has a unique identifier (ID) associated with it whereby it may provide an endpoint or network ID that uniquely identifies the communication endpoint in the remote network. An example of an endpoint ID is that of a Mobile Identification Network (MIN), Internet Protocol (IP) v4/IPv6 address and similar.
Vehicle data that is available from the vehicle across the VCS may include any of diagnostic, operational, performance, proprietary, service, and parameter data. The VCS is preferably electronic and in communication arrangement with the engine control unit (ECU) or engine control module (ECM), used interchangeably herein, as well as the DPS to provide current and historical information to the present invention. Preferably, the vehicle data may be communicated across the device protocol system using one or more defined protocols, and which are further preferably compliant with OBD II. Preferential protocols include those that are OBD II compatible including: (1) SAE J1850 PWM; (2) SAE J1850 VPW; (3) ISO 9141-2; (4) ISO 14230 KWP2000; and (5) ISO 15765 CAN bus (referenced herein as “defined protocols”).
Further from
In one or more preferred embodiments, the broker 260 is situated as network middleware that is responsible for receiving and sending messages to the device controller 230. The broker 260 is also responsible for managing triggers or “conditions” that would trigger vehicle data to be sent to an App or Apps 290. For example, an Application 290 may have commands indicating it is to receive vehicle data only when a vehicle speed approaches eighty miles per hour. The broker 260 also maintains a mapping between the Device ID and the Network ID (or endpoint ID).
By the broker maintaining the mapping, an Application may address the device by Device ID only thereby enabling device mobility across different networks that may require different Network IDs. It will be appreciated by those skilled in the art that a Network ID can change for various reasons, where, for example, a MIN may change if the device owner switches to a new network service provider. Similarly, the IP address may change if the device is moved to a different local network. However, by further example, a device ID such as VIN is typically bound to the life time of the device. Therefore, as in the present invention, by decoupling Device ID from Network ID, service portability and mobility to Applications is also provided for.
In one or more further preferred embodiments, the broker 260 will query the device profile 265 upon the receipt of a message from the App service module 285 that is addressed to a device 210. The query will be an attempt to find a communications module network ID for the device that is being addressed.
Similarly, in one or more further preferred embodiments, when the broker 260 receives a message from the device, it will decode the message and store it in the vehicle data store 270. The broker 260 will also then check to determine if there is a pending request from an Application 290 waiting for the message. If there is a pending request, the communication server aspect of the broker 260 will send the data to the Application 290 through the App service module 285.
In one or more further preferred embodiments, the device profile 265 may further contain other information about the device such as vendor, manufacturing date and etc.; and, the vehicle data store 270 may, to improve data retrieval times, partition vehicle data by reporting time intervals and Vehicle Identification Number (VIN) and by indexing each measurement by the values in a data collection.
In further preferred embodiments, the access control module 280 provides for enabling vehicle owners (or vehicle assignees such as a repair shop or authorized other under control of the vehicle) to control how their vehicle data will be shared. Preferably, an owner can set up a data sharing profile (i.e., user profile) with identifiable attributes, such as: VIN, User ID (the entity that will receive and use the data), Authentication and Authorization rules (whether authentication and authorization from the user is required and the type of authentication and authorization), duration (sharing start time and duration), etc. The profile is then stored in the access control module 280.
In further preferred embodiments, the App service module 290, in providing for processing requests from applications to access vehicle data, may encounter that many applications may request the same vehicle data. In response, the App service module may implement data caching to speed up processing times. Operationally, when the App service module receives a request from an app 290 to access data from a vehicle, it communicates with the access control module 280 to determine if this request has been authorized by the vehicle owner. If the owner has not authorized the data access, the module will reject the request from the app.
Typically, in the present invention, the App service module 290 provides two types of data service to Applications. One type of service is to retrieve historical data records from a vehicle. The other service is to retrieve the current vehicle data, where the current vehicle data may be further divided into: (a) One time single request and (b) Tracking request (based on time or geographical area). Historical data can be serviced from the vehicle data store 270. If the request is for “current” data, the App service module will communicate with the broker 260 to send the “current” request to the device 210.
In the present invention, a typical message that may be passed between the DPS and the SBS includes three primary portions: a header, service data and proprietary data.
The header preferably includes the length of message or any message structure information to aid in the decoding of the message. The header includes a Network ID that uniquely identifies the communication module 240 of the device 210 that is sending/receiving the message. The header can also include an identifier to uniquely identify the device sending or receiving the message. The device ID can be a VIN, for example. The header can include a session identifier if the message is sent as part of a communication session between the DPS and SBS and multiple messages may be provided during a single session.
The service data portion preferably includes vehicle data and commands. The proprietary data portion preferably includes proprietary data that may require third party codec(s).
Operationally, the present invention, in one endeavor, has been prototyped using a CAN controller to extract vehicle diagnostics from a test vehicle via an OBD II connector. It will be appreciated that a microcontroller that interfaces with the CAN bus to decode/encode CAN parameters can be implemented while also interfacing with the Controller using RS-232 over a serial port. The CAN bus is a message-based vehicle bus standard protocol designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. It will also be recognized that the CAN bus though originally designed for automotive applications, is also suitable and used in various other industries including industrial automation and medical equipment applications. The table below shows a single example of various information that the present invention can collect and export through the OBDII connector, though it should be understood that the present invention is not limited to that represented in the table below:
Data and message traffic is passed bilaterally, depending on the push or pull of the system, across the network 330. Messages that are passed from the client or device side 310 across the network 330 to the SBS at 340, are received by the SBS (or service side) for processing. In one or more preferred embodiments, the SBS is a service-based activity which based on at least one and preferably a cluster of servers at a location remote from the device. The SBS is able to accommodate the receipt, decoding, encoding, storage, and connectivity for communications with other interfaces in accordance with the requisite commands of the message content and/or associate data owner (i.e., client, owner of device, or owner of vehicle).
Preferably vehicle data received and processed at the SBS is then available for access and utilization via a web-based application or server site in the cloud at 350. Communication of the post-SBS processed vehicle data is passed to the cloud via a web or http protocol/standard at 345 and is preferably encrypted. Similarly, data post-SBS processed is also available via communication device 360 via the appropriate application protocol across a web or http protocol/standard at 355.
Data and message traffic that is provided from a smartphone application 360 or via a web browser 350 is passed to the SBS 340 for processing over a common standard at 345 or 355. The SBS then refers the commands and formats, as instructed or in accordance with a rule-based instruction in relation to a client's user profile (e.g., security, access, encryption, etc.), across the network 330 to the DPS 310. The appropriate DPS 310 is identified by its device ID or instruction, discussed previously.
It will be appreciated by those skilled in the art that there are a variety of implementations of the present invention and the inclusion of technologies, such as protocols and communication standards, which also will enable the present invention to perform as designed.
The SBS receives the transmitted message at 440 and processes in accordance with the instructions, user profile, or other command information at 450. The SBS may communicate with applications, external interfaces, vehicle manufacturers, vehicle owners, diagnostic systems, mobile applications, mobile devices, and device protocol systems, etc. depending on the instructions or needs for processing. The SBS will also store the received and decoded vehicle data at a data store in accordance with the rule set of the client profile or other instruction at 460.
Preferably, the data store is located at an address on the remote network associated with an endpoint ID and a network ID. In one or more preferred embodiments, the SBS further includes: a device profile module for storing the mapping of the device ID and the endpoint ID to one or more addresses on the remote network, whereby a device ID includes at least one endpoint ID; a data store being at least one of the one or more remote devices for storing received vehicle data; and, an applications service module for processing requests from software applications to access vehicle data.
It will be appreciated by those skilled in the art that the term ECU may also be used interchangeably with the term or equivalent of powertrain control module (PCM) which is typically referenced to be a electronic control unit capable of controlling a series of actuators on an internal combustion engine to ensure the optimum operation.
As used herein, the term vehicle in one or more embodiments may include automobile, mobile transport equipment, industrial equipment, medical device, or device having a communication system, ECU, or similar, to provide data across a communication protocol.
Although the present invention has been described in accordance with the embodiments shown, one of ordinary skill in the art will readily recognize that there could be variations to the embodiments and those variations would be within the spirit and scope of the present invention. Accordingly, many modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims. Many other embodiments of the present invention are also envisioned.
Any theory, mechanism of operation, proof, or finding stated herein is meant to further enhance understanding of the present invention and is not intended to make the present invention in any way dependent upon such theory, mechanism of operation, proof, or finding. It should be understood that while the use of the word preferable, preferably or preferred in the description above indicates that the feature so described may be more desirable, it nonetheless may not be necessary and embodiments lacking the same may be contemplated as within the scope of the invention, that scope being defined by the claims that follow.
