The present invention relates generally to telematics methods and systems and more particularly, to the configuration of telematics systems and devices.
Telematics systems typically combine telecommunications and information processing, and frequently involve automobile systems that combine global positioning system (GPS) satellite tracking and wireless communications for automatic roadside assistance and remote diagnostics. Some vehicle telematics systems monitor for vehicle diagnostic trouble codes that are formed from sensory inputs from various electronic modules in the vehicle.
Telematics systems promise to combine vehicle safety, entertainment and convenience features through wireless access to distributed networks, such as the Internet. Such systems are distinguishable from hardware-centric audio and vehicle control systems that are built into devices custom designed for each vehicle. By contrast, vehicle telematics systems may include infotainment delivered by plug-and-play hardware whose functionality can be upgraded through software loads or simple module replacement. It is anticipated that significant new revenue streams will be opened up to automobile manufacturers and service providers through the products and services made available through telematics systems.
In the field of vehicle telematics, technologies have been devised that contribute to expanding the use of commercial and personal vehicles from merely a form of transportation to acting as communication hubs. According to these technologies, a vehicle is able to communicate wirelessly with remote systems in order to serve or facilitate a number of objectives including objectives related to safety, navigation, information gathering, entertainment and education. Communications with the vehicle typically involve a cellular phone or other communication device that is able to send and receive communications from outside the vehicle.
Beginning with model year 1996, the Environmental Protection Agency (EPA) required vehicle manufacturers to install on-board diagnostics (OBD-II) for monitoring light-duty automobiles and trucks. OBD-II systems include microcontrollers and sensors that monitor the vehicle's electrical and mechanical systems and generate data that are processed by a vehicle's engine control unit (ECU) to detect any malfunction or deterioration in the vehicle's performance. Most ECUs transmit status and diagnostic information over a shared, standardized electronic bus in the vehicle, which effectively functions as an on-board computer network with many processors that transmit and receive data. The primary computers in this network are the vehicle's electronic-control module (ECM) for monitoring engine functions and power-control module (PCM) for monitoring the vehicle's power train. Data available from the ECM and PCM include vehicle speed, fuel level, engine temperature, and intake manifold pressure.
Data from the above-mentioned systems are made available through a standardized, serial 16-pin OBD-II connector, which usually is disposed underneath the vehicle's dashboard. When the vehicle is serviced, data from the vehicle's ECM and/or PCM is typically queried using an external power train-diagnostic tool that plugs into the OBD-II connector. The vehicle's engine is turned on and data is transferred from the engine computer, through the OBD-II connector, and to the external engine-diagnostic tool. The data, in the form of diagnostic trouble codes, is then displayed and analyzed to service the vehicle. Some vehicle manufacturers also include complex electronic systems in their vehicles to access and analyze some of the above-described data. Such systems collect and transmit data through a wireless network. These systems are not connected through the OBD-II connector, but instead are wired directly to the vehicle's electronic system when the vehicle is manufactured.

Before describing the invention in detail, it is useful to describe an example environment with which the invention can be implemented. In a telematics service architecture a telematics service provider may operate one or more telematics server suits. The telematics server suites may provide automotive telematics services to a plurality of authorized service users via a global network. The architecture may further comprise a plurality of vehicles. These vehicles may include electronic networks, such as control area networks, UART based networks, discrete analog/digital input/output ports, etc. Additionally, these vehicles might include a plurality of vehicle interface modules, generally one per vehicle, and connected to the vehicle's electronic networks.
The configurable embedded telematics architecture may further comprise one or more wireless communications networks connected to the global network for bidirectional data transport between the VIMs and the one or more telematics server suits. The server suites may encompass all the system control and data management utilities, user and vehicle access interfaces, and service applications needed to support the automotive telematics services supported by the plurality of vehicle interface modules. Authorized service users might be, for example, individuals that own vehicles or personnel in organizations that own vehicles or own fleets of vehicles. Authorized service users might also be, for example, groups of individuals that work with vehicles or vehicle data in various roles. In some embodiments, to qualify as an authorized service user the user needs to be registered with the telematics service provider.
In some embodiments, telematics service users may have a need for communication with remote vehicles via a communications network. Actual service interests, interactions between users, servers and vehicles, however, may vary widely between users and user groups. Services might comprise upstream vehicle initiated data transport, downstream vehicle initiated data transport, user initiated data transport, server initiated data transport, or some combination of these.
In various embodiments, data collection from vehicles might include data collection while moving or parked. For example, while a vehicle is in operation, a large amount of vehicle data may be available on one or more of the vehicle electronic networks. A specific telematics service may be characterized by the specific portion of available vehicle data that is selected, monitored, processed, stored, forwarded, or some combination of these. A telematics service might be forwarded to the user or server suite for immediate or later use. In some embodiments, the use of VIM resources, such as processing power and memory, might be designed to improve economical service operation.
In various embodiments, upstream services may include, for example, critical event detection, e.g., theft, accident, etc.; driver performance monitoring, speed, rpm, idle time, max speed, etc.; instant vehicle diagnostics, e.g., detection of diagnostic trouble codes, break action, etc. In some embodiments, upstream services may include, for example, long-term vehicle wear and tear monitoring, e.g., power-train, transmission, break system, tire pressure, oil and other fluid quality and quantity, etc.; location finding, e.g., tracking, navigation, etc. In some embodiments, only data that is time critical may be sent upstream in real time, while other service related data may be stored for possible later retrieval.
Some embodiments of the systems and methods described herein might include user-vehicle interactions. For example, these services might comprise commands to vehicle subsystems and components or data queries to the vehicle. For example, in various embodiments, users may send downstream commands to the VIM to query vehicle location, diagnostic trouble code and/or vehicle drive status, or to remotely operate door locks, windows, heating/cooling systems, horns and lights, or even enable/disable the engine.
Generally, not all users and user groups of a telematics system might desire or need the same services. In some embodiments, services may differ in the type and amount of data collected from vehicles either in real time or in a store and forward operation and in the way access to this data is provided. A telematics service architecture that includes all user services requires a commensurate large range of VIM processing and memory resources. In contrast a telematics service architecture that is limited to services requested by users or user groups might require much lesser VIM processing and memory resources.
In some embodiments, user services might also differ in the amount of data transport resources consumed. For example a tracking service may require periodic location updates at a rate of a few seconds, while a trip metering service only requires a data transfer at the beginning and at the end of an ignition cycle. In some cases, the wireless part of the data transport may be metered by the wireless service provider. Limiting the data transport to those services that a user or user group consumes, preserves wireless data transport resources and might lower cost to the user, for example, when cost of wireless services are set based on usage rather than a fixed fee.
In some embodiments, manufacturers might equip vehicles with a variety of standard electronic networks such as single-wire and dual-wire control area networks (CANs), high-speed CANs, Fault Tolerant CANS, Class 2, UART based networks such as ISO and K-line, and others. The physical layers of these networks may be standardized. However, actual networks implemented in a vehicle as well as the actual message libraries used to communicate on these networks might vary from manufacturer to manufacturer. Additionally, these networks might vary from model to model or model year to model year, even within the same manufacturer. To be independent of a specific vehicle manufacturer, model or year, a telematics service architecture may need to provide a model specific VIM configuration capability.
The server suite 200 includes one or more servers, which may be co-located or distributed geographically and may comprise a user management utility 210. The user management utility 210 may control and manage user access, store user profiles, monitor user service consumption and billing. Additionally, the user management utility 210 may include application server 220 with a plurality of service applications. VIM server 230 may establish and maintain data connections between the plurality of vehicles and service applications. In some applications, web server 240 might provide interactive user access to telematics services. In various embodiments, operation and maintenance entity 250 may provide service infrastructure monitoring and maintenance. Additionally, telematics database 260 may store and retrieve user, service and vehicle data records.
In the illustrated embodiment, the global network 300 may comprise one or more wireless network portions 310, one or more wired network portions 320, or a combination thereof. In some embodiments, network portions 310 and 320 might be integrated in such a way that VIM's can bi-directionally communicate with fixed devices on the wired portions while moving. The wired network portion may include an internet connection, telephone connection, other wired communication systems, or some combination of systems. The wireless portion may be a cellular or PCS network, a WiFi or Imax network, a satellite network or any other wireless network or combination of wireless networks.
In some embodiments, the plurality of VIM's 400 may provide the embedded component of the configurable telematics service architecture. In various embodiments, the VIM may be an integrated hardware module. As illustrated in
In some embodiments, the introduction of these components in combination with over-the-air access from the wired portion of the global network, might allow authorized users and user groups to customize telematics services so as to meet these user's specific requirements. In some embodiments, the user configuration utility and user configuration module may be designed in such a way as to minimize the need for on-board resources and data transport resources for a wide range of telematics services.
In various embodiments, the vehicle adaptation utility 271 might store vehicle specific electronic networking information for a plurality of vehicle makes and models in a data-base. In some embodiments, it may further provide a web accessible graphical user interface for users to select a particular vehicle and configure the service for this vehicle. When selected, vehicle adaptation utility 271 may send the selected vehicle specific electronic networking information over the air to the VIM.
In the VIM, vehicle configuration utility 460 may receive electronic networking information. Additionally, it may reconfigure the vehicle network drivers 453 based on the information received. In some embodiments, these two components may allow authorized users to remotely configure the telematics service for specific vehicle makes and models after installation of VIM's in vehicles at the time of service activation. Some embodiments might also provide a capability to remotely reconfigure a VIM that has been transferred from a different vehicle.
In some embodiments, after a user completes a selection, the service adaptation utility 272 may store the selected services along with the defined service parameters for service execution by the user management utility 210. In various embodiments, when users make changes to the selection of service parameters, the user management utility 210 might send the new user selected service parameters over the air to the service configuration module 462.
Various embodiments may include functionality to allow for downloadable firmware and software upgrades. For example, a service provider may activate a utility 251 that performs such upgrades. These upgrades might be part of a scheduled diagnostic routine for specific VIM's or in response to an exception mode report from a specific VIM via diagnostic module 430. In some embodiments, the utility might then interact with the diagnostic module 430 to trouble shoot the on-board resources 440. The user might be notified of the results of the trouble shooting. For example, the user might be told that a problem has been found, that no problem has been found, etc. In some embodiments, user notification may allow users to select their notification preferences. For example, in various embodiments, email, phone, SMS, Web based, or other methods of communication might be used to transmit a notification. Additionally, in various embodiments, a user might only be notified when a problem is found. In some embodiments, no VIM interaction is required.
