Definitions

  • the present invention relates to the technical field of finding consumption data, in particular of motor vehicles.
  • Web 2.0 refers in addition to specific technologies or innovations such as cloud computing primarily to a changed use and perception of the Internet. Users create, edit and distribute content quantitatively and qualitatively, supported by interactive applications.
  • Web 2.0 applications can be demonstrated by their membership, popularity and frequency of use.
  • Facebook is the largest social network with about five hundred million registered users in February 2010.
  • Alexa included Blogger.com, Facebook, Wikipedia and YouTube four applications of Web 2.0, which are particularly often used by young visitors aged fourteen to 29 years.
  • Error messages can then be queried later by a specialist workshop via standardized interfaces.
  • Access for vehicle diagnostics via OBD-2 is the vehicle's 16-pin OBD-2 diagnostic socket, which is often used not only for the multi-vendor, exhaust-related OBD-2 diagnostic protocol, but also for the manufacturer's specific diagnostics protocols.
  • the results of the on-board diagnostics can also be read out by special software applications on commercially available notebooks. Via the diagnostic interface, the connected workshop or notebook computer sends (via additional required protocol interpretation and signal level conversion hardware) commands to one of the ECUs, which is activated via its address, and then receives results back.
  • commands are available for reading the ID (precise model name and version) of the ECU, for reading and resetting the above-mentioned error entries, for reading so-called measured value blocks (also called standard displays), for reading, testing and setting various setting parameters (so-called adaption channels) and (especially for development) for direct reading and writing of memory cells in the control unit.
  • Bluetooth Well known in the art for transmitting data between devices over a short distance is the Bluetooth standard, cf. for example http://de.wikipedia.org/wiki/Bluetooth
  • App generally refers to any form of application program. In linguistic usage, however, these meanwhile mostly mean applications for modern smartphones and tablet computers, which can be procured via an online shop integrated in the operating system and thus installed directly on the smartphone.
  • Carbon dioxide is produced especially when burning fossil materials such as oil, gas or coal. This combustion takes place mainly in power generation in power plants and in petrol or diesel-powered motor vehicles (motor vehicles).
  • Pollutant reductions of the air can be achieved for motor vehicles with internal combustion engines on the one hand by the development of more efficient and thus more economical engines, on the other hand also by a more conscious, energy-saving driving.
  • the object of the present invention is to provide a system and a method by means of which real fuel consumption values for all motor vehicles on all routes with the permanent goal of finding Consumption and thus minimum carbon dioxide can be displayed and replaced.
  • the present invention is based on the determination of the real fuel consumption values of a motor vehicle on a certain route and on the corresponding visualization of these values, in particular in a, for example global, Internet portal, by means of which the combined vehicle diagnostic and geoposition data are visualized via the O [n-] B [oard-] D [iagnose] port of the vehicle on the one hand and a Geopositionsempftuler on the other hand can be read and transmitted via a mobile phone connection to a server.
  • the diagnostic data can be queried initiated by a smartphone app and then transferred to the portal.
  • the transmission of the determined data for reducing the amount of data in bundled and / or compressed form can take place.
  • the transmission may be triggered by geolocalized triggers and, for this purpose, ranges / positions may be defined that include such Trigger transmission (Location Based Transmission).
  • n m assignment (n to m") between terminals and system user accounts can be used - a terminal can have multiple users, each user can use multiple terminals.
  • a telematics or mobile radio module already installed in the motor vehicle can be used, and it is precisely this module which can interrogate the diagnostic data via OBD or directly from the controller A [rea] N [etwork] bus.
  • the geoposition of the corresponding receiver can be used in the smartphone.
  • the geoposition can be used by a receiver installed in the vehicle, which can be queried, for example, directly by a telematics module via controller A [rea] N [etwork].
  • the data transmission between the OBD connection and the smartphone can take place via an OBD Bluetooth adapter.
  • the Internet portal may display distance-based leaderboards (for example, in the form of "top ten") of fuel consumption values.
  • the comparability on the basis of the traffic flow and the weather conditions can be made by the inclusion of information provided by third parties.
  • the consumption comparison values can be calculated per overlapping route sections.
  • the sections may have a minimum length, for example at least one kilometer or at least ten kilometers.
  • the consumption comparison values and leaderboards can be specified per route section per vehicle class (compact car, middle class, upper middle class, upper class, sports car, commercial vehicle class).
  • the consumption best lists per vehicle can be specified.
  • the fuel consumption lists per vehicle and per engine can be specified.
  • total route lists per country, per manufacturer, per vehicle class, per vehicle, per vehicle and per engine can be created independently of the route.
  • the most fuel-efficient vehicles can be chosen.
  • the Internet portal can send registered users the current best consumption for the current route section while driving.
  • other driving recommendations can be sent, for example, the previously determined best engine speed and speed.
  • the consumption values could be determined manually, that is to say by the user or driver, either by using the on-board computer (if present) or by explicitly refueling after completion of the traveled route and subsequent calculation.
  • This problem avoids the present invention in that reliable data are read out of the vehicle via the standardized O [n] B [oard-] D [iagnosis] interface. These are at least the vehicle type (make, model, year of manufacture, engine, etc.) and the fuel-air mixture, which is the basis for the fuel consumption calculation.
  • the data is read out via a standard OBD adapter, which uses Bluetooth or USB to transfer the data to a paired smartphone or to a permanently installed one Telematics box or alternatively to a notebook or a P [ersonal] C [computer] transmits.
  • a standard OBD adapter which uses Bluetooth or USB to transfer the data to a paired smartphone or to a permanently installed one Telematics box or alternatively to a notebook or a P [ersonal] C [computer] transmits.
  • the smartphone has a receiver for determining the geographical position, for example based on G [lobal] P [ositioning] S [ystem], Galileo, Glonass.
  • a particular application program or app within the scope of the present invention periodically collects OBD data, geoposition, and time at the same time, for example, every ten seconds, and merges them into a data packet.
  • These periodically collected data packets can be uploaded from the smartphone or the app directly to the Internet portal or collected in the smartphone and put at a later date by the user in the portal.
  • a key application of the Internet portal is the comparison of their own, route-specific consumption values with those of other users. Since most car drivers are interested in a constant optimization of their fuel costs, the portal allows the user on the one hand to consider the purchase of a more fuel-efficient vehicle, on the other hand to minimize his driving behavior in terms of fuel consumption compared to identical vehicles.
  • the present invention relates to the use of at least one system according to the type and / or a method set forth above for determining and displaying fuel consumption values of the motor vehicle determined by the diagnostic data on at least one route of the motor vehicle determined by the geoposition data.
  • These combined vehicle diagnostic and geoposition data can be visualized by means of at least one, in particular global, Internet portal.
  • Fig. 1 illustrates the basic operation of the present invention by means of a system 10 according to the present invention, which operates according to the method according to the present invention.
  • MIL Malfunction Indicator Light
  • exhaust gas-relevant faults can be recorded in a memory and read out via a standardized plug and a serial interface.
  • this interface not only outputs stored (error) values but also a large number of current vehicle, engine and exhaust gas-relevant data records.
  • an OBD-B [lue] T [ooth] adapter 2 (cf. FIG. 2) is attached to the OBD socket 1 of the vehicle 20, which is generally located in the interior of the vehicle 20 below the dashboard on the driver's side , Fig. 2A ) or an OBD-U [universal] S [erial] B [us] adapter 2 (cf. Fig. 2B ) connected.
  • OBD-U [universal] S [erial] B [us] adapter 2 cf. Fig. 2B
  • alternative or further adapters for example of the type OBD-Sub D, are also conceivable.
  • the OBD-B [lue] T [ooth] adapter (cf. Fig. 2A ) is very advantageous because it allows particularly easy access to the desired data.
  • other approaches to the vehicle-specific data sets are conceivable, for example, by other adapters directly to the bus of the vehicle 20, for example, on the C [ontroller] A [rea] N [etwork] -Bus or Flexray accessed.
  • the adapter 2 is now coupled with a smartphone 4, in which also Bluetooth 3 is switched on (so-called “pairing”).
  • An application according to the invention on the smartphone (so-called App 5) is started by the user or driver.
  • vehicle-specific data such as manufacturer, model, year of manufacture, engine are read out via the OBD-B [lue] T [ooth] adapter 2, preferably via the V [ehicle] I [dentification] N [umber] Part of the OBD parameter set.
  • the user or driver actuates the corresponding button of the app.
  • At least the fuel-air mixture is read out at periodic intervals, for example every ten seconds, via the OBD interface.
  • Further data may be the engine speed and the outside temperature.
  • the interval for reading out the data is assumed to be exemplary with ten seconds within the scope of the further explanations, but shorter intervals may also be expedient.
  • the geoposition and the time are read out directly via the smartphone 4 at the same time. This results in the simplest case, a data packet from time, geographical longitude, latitude, fuel-air mixture.
  • the fuel-air mixture is read out via the OBD record M [ass] A [ir] F [low rate].
  • This record has two bytes (A and B). This results in the calculation of the average fuel consumption per one hundred kilometers according to the known formula to [(A * 256) + B] / 100.
  • the stated calculation of the consumption can be done both in the smartphone 4 directly and on the server 8.
  • the unique V [ehicle] I [dentification] N [umber] is transmitted for unambiguous assignment within the server application.
  • the data packets created every ten seconds in the exemplary embodiment can be used for a direct (so-called online mode) via a cellular connection 6, for example via GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunications System), and / or over the Internet 7 to the server 8 and on the Internet portal 9 are uploaded or initially stored in the smartphone 4 and uploaded at a later date by the user (so-called offline mode). This can then also be done via the smartphone 4 or after transferring the data from the smartphone 4 to a PC over just the latter.
  • GSM Global System for Mobile Communications
  • UMTS Universal Mobile Telecommunications System
  • a time-delayed live transmission of the data in bursted and / or compressed form is optionally provided. This involves a device-internal collection of the periodically acquired data. These data packets are bundled when certain events occur and / or compressed to the server 8 or to the backend.
  • the uploaded data are displayed "live" in the portal 9, thus allowing a tracking of the journeys of the users by visitors of the portal 9, which increases the attractiveness of the portal 9.
  • this live tracking may be delayed.
  • the overall system 10 is suitably protected against data manipulation. This applies both in terms of data integrity as well as with regard to the protection of the system 10 against accidental interference (reliability, caused for example by a technical defect) or against deliberate interference (attack security) in the functionality.
  • a message authentication code using a symmetric method can be used in an advantageous manner. Without knowledge of the secret key, this does not make it possible to manipulate a generated data record or to generate new - valid - data records.
  • the display of the uploaded data records in the portal 9 takes place on a geographical map and / or road map (for example, Google Maps, Open Street Map).
  • the corresponding "mapping" is possible through the geopositions read in the form of distance-dependent statistics, which are visualized on the portal 9.
  • a route-dependent consumption value comparison (“benchmark”) can be carried out.
  • the Internet portal 9 operates on a user account basis, that is, the user has access to a specific user assigned to this specific user after registration and registration.
  • the term "user” is defined here by the system-wide unique eMail address that has to be entered during the account registration.
  • An unambiguous assignment of acquired data to a specific terminal / vehicle 20 can take place via this.
  • User accounts can be linked to one or more devices. This allows a user-based statistical evaluation. Especially about the possibility assigning individual terminals multiple user accounts (shared vehicle 20, for example, in the context of car sharing), the overall system 10 offers the opportunity to contrast the influence of individual driving styles.
  • Such multi-user operation of the vehicle 20 requires a terminal-side configuration option. This can take place on the one hand via a suitable surface (M [ensch] M [aschine] I [nterface]), on the other hand, however, by further identification methods commonly used in the automotive sector, such as, for example, driver recognition by the key used.
  • a suitable surface M [ensch] M [aschine] I [nterface]
  • the Internet portal 9 requires a user registration in a known manner (username, password). There is a distinction between a free (“Basic Member”) and a paid (“Premium Member”) membership, the latter having extended features.
  • the premium member it is possible for the premium member to manage several vehicles 20 under his account and to obtain extended information and statistics on the placements, users, vehicles 20 and / or routes.
  • Another advantage is the possibility of using a return channel from the portal 9 to the smartphone 4, which already during driving reports driving recommendations based on the previous best values on the corresponding route.
  • the routes can be assigned to a road and a corresponding road section.
  • the Internet portal 9 can access a navigation database or road map data.
  • the consumption values valid for the respective route section which are available every ten seconds depending on the selected sampling rate, are used to determine the average consumption per hundred kilometers, and the calculated average value in the form of a ranking list, for example a top ten List, displayed in portal 9 directly on the route section (cf. Fig. 4 the example of two drivers).
  • This consumption list is only valid for one direction of travel.
  • the Heading is required, which - can be determined with the Smartphone 4 - within certain limits reliably.
  • the direction can also be determined on the server side from the string of pearls of the position reports.
  • the opposite direction requires separate statistics; For example, there are very different consumptions on inclines or slopes in the opposite direction.
  • the data collected on the server 8 and the associated statistics can be used to send vehicle-specific and route-specific consumption values, if appropriate, including further driving recommendations, for example ideal engine speed and speed, to the user or driver. When taken into account by the driver, an environmentally and cost-conscious driving is promoted even further.
