Description

System and Method for Remote-Controlled Installation ofSoftware in Motor Vehicles THE BACKGROUND OF THE INVENTION AND PRIOR ART The present invention relates generally to the adjustment of amotor vehic|e”s Characteristics after that the vehicle has beenput into operation. More particularly the invention relates to asystem according to the preamble of claim 1 and a correspon-ding method. The invention also relates to a computer programproduct and a computer readable medium. ln today”s motor vehicles a relatively large amount of functio-nality is implemented based on software. Further, it is reason-able to assume that the proportion of software-implementedfunctionality will increase in the future. For example, it can beexpected that various services will be offered, which will allowadjusting of an existing vehic|e”s behavior, its characteristicsand/or performance depending on the driver”s or the owner”s re-quests at various points in time.

DE 10 2012 001 047 describes a method for updating an info-tainment system in a motor vehicle by a software update packa-ge sent out from a server.

US 2004/0093264 shows an Eco-Driving diagnostic system cap-able of quantitatively comprehending fuel consumption with res-pect to each event and environmental-load emissions owing tothe fuel consumption. Here, sensor information is sent from thevehicle to a center via a radio communication network. Basedthereon, fuel consumption owing to the vehic|e”s driving and en-vironmental-load emissions are calculated; and on the furtherbasis thereon, advices are created to promote Eco-Driving to thedriver via for example a mobile phone or terminal.

US 6,181 ,994 discloses a solution for loading an advanced diag-nostics program into a vehicle on demand with results being sent back to a diagnostic center. Thus, an onboard computercan obtain problem diagnostics information and data while onthe road.

US 2011/0307336 reveals a method for updating software com-ponents of a motor vehicle via a service facility outside the ve-hicle. Before updating a particular software component, the dri-ver receives an offer from the service facility, and the updatingis enabled only if the driver accepts the offer. Identification dataand vehicle configuration information are sent repeatedly to theservice facility without the involvement and/or notification of thedriver.

PROBLEIVIS ASSOCIATED WITH THE PRIOR ART Thus, various solutions are known for informing a driver and ef-fect remote installing of software in a motor vehicle in responseto various events experienced by the vehicle. However, there isyet no solution that provides installation of tailor-made softwarefor improving the driving performance efficiency of a particularmotor vehicle in a specific manner SUMMARY OF THE INVENTION The object of the present invention is therefore to solve the abo-ve problem, and thus offer a solution capable of modifying thedriving performance of a given motor vehicle aiming at renderingfuture operation of this vehicle more efficient in at least one way.

According to one aspect of the invention, the object is achievedby the initially described system, wherein the data message fromthe motor vehicle received in the central service node containsat least one operation parameter describing at least one aspectof how the motor vehicle has been operated during a well-defi-ned period. The specific software component selected in respon-se to the data message is configured to cause adjustment of atleast one parameter of a drive train in the motor vehicle, which, in turn, will influence a driving performance of the motor vehicle.

This system is advantageous because it enables adaption of thevehicle”s driving characteristics in such a manner that it for ex-ample matches a typical route profile for the vehicle, a particulardriver”s way of driving and/or the driver”s wish to improve a cer-tain attribute of the vehicle”s performance.

According to one preferred embodiment of this aspect of the in-vention, the specific software component contains an amount ofprogram code configured to be installed and executed in theprocessing unit in the motor vehicle. ln other words, the specificsoftware component constitutes the actual software that will ac-complish the adjusted driving performance. This is beneficialsince thereby also functionality that has been developed aftermanufacturing a vehicle can be implemented in this vehicle.

According to another preferred embodiment of this aspect of theinvention, the specific software component contains key dataconfigured to unlock an amount of program code already resi-ding in a memory unit of the motor vehicle. After unlocking theprogram code by the key data, the program code is configuredto be installed and executed in the processing unit in the motorvehicle, thus adjusting the driving performance of the vehicle.This is advantageous, since it enables convenient installing ofrelatively large amounts of software also when the vehicle onlyhas access to a data connection with highly limited bandwidth.

According to yet another preferred embodiment of this aspect ofthe invention, the at least one operation parameter describes:temperature values registered in at least one drive-train relatedcomponent in the motor vehicle, pressure levels registered in atleast one drive-train related component in the motor vehicle,fluid levels registered in at least one drive-train related compo-nent in the motor vehicle, accelerometry data reflecting accele-rations and/or decelerations experienced by the motor vehicleand/or parts thereof, route data designating a geographic path along which the motor vehicle has travelled and/or slope datareflecting a respective steepness of any ascends and/or des-cends experienced by the motor vehicle. Consequently, a widerange of attributes can be provided as a basis for selecting howthe driving performance shall be adjusted.

According to still another preferred embodiment of this aspect ofthe invention, the system includes a second database containingvehicle configuration data for the motor vehicle. Moreover, thecentral service node is configured to: retrieve the vehicle confi-guration data in respect of the motor vehicle from the seconddatabase, and select the specific software component on thefurther basis of the retrieved vehicle configuration data. Thisallows an adequate selection of software while only requiring amoderate transfer of data from the vehicle.

According to another preferred embodiment of this aspect of theinvention, the data message, as such, also contains vehicleconfiguration data in respect of the motor vehicle; and the cent-ral service node is configured to select the specific softwarecomponent on the further basis of the vehicle configuration dataincluded in the data message. This is advantageous becausethereby vehicles can be modified/upgraded independently with-out informing the central service node, and still adequate upda-ting software can be selected by the central service node.

According to a further preferred embodiment of this aspect of theinvention, the specific software component is configured to causethe at least one parameter of the motor vehicle”s driving perfor-mance to be adjusted in such a manner that a fuel consumption ofthe motor vehicle is expected to be reduced given that it is opera-ted analogous to what is reflected by the received data message.Hence, the overall fuel usage can be economized. Of course, as afurther consequence, the consumption of any additives to a cata-lytic exhaust cleaning process (e.g. AdBlue) can also be reduced.

According to yet another preferred embodiment of this aspect of the invention, the specific software component is configured tocause the at least one parameter of the motor vehicle”s drivingperformance to be adjusted in such a manner that a torquecharacteristics of an engine in the motor vehicle is adaptedaiming at matching the requirements of an expected future useof the motor vehicle given that it is operated analogous to whatis reflected by the received data message. Consequently, forexample increased torque can be achieved in order to improvethe vehicle”s ability to handle uphill slopes and make overta-kings, or the torque can be decreased to save fuel.

According to another aspect of the invention, the object is achie-ved by the method described initially, wherein the data messagereceived from the motor vehicle contains at least one operationparameter that describes at least one aspect of how the motorvehicle has been operated during a well-defined period. Thespecific software component sent from the central service nodeis configured to cause adjustment of at least one parameter of adrive train in the motor vehicle that influences a driving perfor-mance of the motor vehicle. The advantages of this method, aswell as the preferred embodiments thereof, are apparent fromthe discussion above with reference to the proposed system.

According to a further aspect of the invention the object isachieved by a computer program product, which is loadable intothe memory of a computer, and includes software for performingthe steps of the above proposed method when executed on acomputer.

According to another aspect of the invention the object is achie-ved by a computer readable medium, having a program recordedthereon, where the program is make a computer perform the me-thod proposed above when the program is loaded into thecomputer.

Further advantages, beneficial features and applications of thepresent invention will be apparent from the following description and the dependent claims.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is now to be explained more closely by means ofpreferred embodiments, which are disclosed as examples, andwith reference to the attached drawings.

Figure 1 shows an overview of a system according to oneembodiment of the invention; andFigure 2 illustrates, by means of a flow diagram, the gene- ral method according to the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE IN-VENTION lnitially, we refer to Figure 1 which shows a system for remote-controlled installation of software in a motor vehicle 110. Thesystem includes a central service node 120 and a first database130.

The first database 130, in turn, contains software componentsSWC which are configured to be applied in a processing unit inthe motor vehicle 110, and thus cause at least one parameter ofa drive train in the motor vehicle 110 to be adjusted in such amanner that it influences a driving performance of the motor ve-hicle 110. For example, applying a software component SWCfrom the first database 130 in at least one processing unit in themotor vehicle 110 may result in an increase/decrease of the en-gine torque, reprogramming of its gearbox, enabling and/or mo-dification of a driving assistance function.

The central service node 120 has a primary interface 125 to-wards at least one network 140, which, in turn, has a secondaryinterface 145 configured to communicate wirelessly with a datacommunication unit 113 in the motor vehicle 110.

The central service node 120 is configured to receive a data message DM from the motor vehicle 110 via the secondary in-terface 145, the at least one network 140 and the primary inter-face 125. ln response to a received data message DM, the cent-ral service node 120 is further configured to select a specificsoftware component SWC from the first database 130. The spe-cific software component SWC is selected based on the con-tents of the received data message DM, and the specific softwa-re component SWC is to be applied in a processing unit in themotor vehicle 110. More precisely, the data message DM con-tains at least one operation parameter describing at least oneaspect of how the motor vehicle 110 has been operated during awell-defined period, say a foregoing month, week, hour; or whencompleting a particular route.

The specific software component SWC is configured to causeadjustment of at least one parameter of a drive train in the motorvehicle 110, which at least one parameter influences the motorvehicle”s 110 driving performance.

According to one embodiment of the invention, the specific soft-ware component SWC is configured to cause the at least oneparameter of the driving performance to be adjusted in such amanner that the fuel consumption for the motor vehicle 110 isexpected to be reduced given that it is operated analogous towhat is reflected by the received data message DM.

According to another embodiment of the invention, the specificsoftware component SWC is configured to cause the at leastone parameter of the driving performance to be adjusted in sucha manner that the engine”s torque characteristics is adapted ai-ming at matching the requirements of an expected future use ofthe motor vehicle 110 given that it is operated analogous towhat is reflected by the received data message DM. ln otherwords, the specific software component SWC may cause an in-creased torque if it is estimated that this would be useful forexample to facilitate overtakings; or the specific software com-ponent SWC may cause a reduced torque to economize the fuel consumption (e.g. in the form of diesel, gasoline, or electricity).Moreover, as a further result thereof, the necessary amounts ofany additives to the catalytic exhaust cleaning process (e.g. Ad-Blue) can likewise be reduced. ln any case the specific software component SWC itself maycontain an amount of program code configured to be installedand executed in the processing unit in the motor vehicle 110.Alternatively, the specific software component SWC may includekey data (e.g. in the form of a string of characters) that is confi-gured to unlock an amount of program code residing in a memo-ry unit 115 of the motor vehicle 110 in an encrypted, or by othermeans protected, format. Then, after having been unlocked bythe key data, the program code in the memory unit 115 is confi-gured to be installed and executed in the processing unit in themotor vehicle 110, and thus accomplish the intended adjustmentof the motor vehicle”s 110 driving performance. ln order to constitute a relevant basis for selecting the specificsoftware component SWC, the data message Dl\/l preferablycontains at least one drive-train related parameter of the motorvehicle 110 and/or other information reflecting how the motorvehicle 110 has been operated recently. Thus, the at least oneoperation parameter included in the data message DM may des-cribe: temperature values registered in at least one drive-trainrelated component in the motor vehicle 110; pressure levelsregistered in at least one drive-train related component in themotor vehicle 110; fluid levels registered in at least one drive-train related component in the motor vehicle 110; accelerometrydata reflecting accelerations and/or decelerations experiencedby the motor vehicle 110 and/or parts thereof; route datadesignating a geographic path along which the motor vehicle110 has travelled and/or slope data reflecting a respectivesteepness of any ascends and/or descends experienced by themotor vehicle 110.

According to one preferred embodiment of the invention, the system also includes a second database 150 that containsvehicle configuration data VCD for each vehicle in a fleet of ve-hicles including the motor vehicle 110. Additionally, in connec-tion with receiving a data message DM from a particular motorvehicle 110, the central service node 120 is configured to: ret-rieve the vehicle configuration data VDC in respect of this motorvehicle 110 from the second database 150; and select the speci-fic software component SWC on the further basis of the retrie-ved vehicle configuration data VDC.

Alternatively, or as a complement thereto, the data message DMmay contain vehicle configuration data VCD in respect of themotor vehicle 110. ln such a case, the central service node 120is configured to select the specific software component SWC onthe further basis of the vehicle configuration data VCD in thedata message DM. Naturally, according to the invention, it is al-so possible that one part of the vehicle configuration data VCDis received via the data message DM, and another part of thevehicle configuration data VCD is retrieved from the second da-tabase 150.

Preferably, the central service node 120 includes, or is in com-municative connection with a memory unit storing a computerprogram product, which contains software for making the centralservice node 120 execute the above-described actions when thecomputer program product is run in the central service node120. ln order to sum up, and with reference to the flow diagram in Fi-gure 2, we will now describe the general method according tothe invention. ln a first step 210, it is checked whether or not a data messageDM has been received from a motor vehicle 110 in the centralservice node 120. lf so, a step 220 follows; and otherwise, theprocedure loops back and stays in step 210. lt is presumed thatthe data message DM has been sent to the central service node 120 over at least one network 140 and a wireless interface 145.The data message DM contains at least one operationparameter that describes one or more aspects of how the motorvehicle 110 has been operated during a well-defined period. ln step 220, in response to the data message Dl\/l, the centralservice node 120 selects a specific software component SWC,which is deemed to be suitable for the motor vehicle based onthe contents of the data message Dl\/l. The specific softwarecomponent SWC is retrieved from the database 130.

Then, in a step 230, the central service node 120 sends thespecific software component SWC to a data communication unit113 in the motor vehicle 110. Analogous to the data messageDl\/l, the specific software component SWC is transmitted overthe at least one network and the wireless interface 145. Thespecific software component SWC is configured to cause adjust-ment of at least one parameter of a drive train in the motor ve-hicle 110, which influences a driving performance of the motorvehicle 110. Preferably, upon receipt of the specific softwarecomponent SWC in the motor vehicle 110, a message is causedto be presented (e.g. optically and/or acoustically) to a driver ofthe motor vehicle 110 asking for the driver”s authorization beforeany measures are taken that result in that software is actuallyinstalled in the motor vehicle 110.

Thereafter, the procedure ends with respect to this pair of datamessage and specific software component. ln practice, however,the central service node 120 of course continues to wait for anynew data messages DM from the motor vehicle 110 as well asany other motor vehicle associated with the service provided bythe central service node 120.

All of the process steps, as well as any sub-sequence of steps,described with reference to Figure 2 above may be controlled bymeans of a programmed computer apparatus. l\/loreover, al-though the embodiments of the invention described above with 11 reference to the drawings comprise a computer apparatus andprocesses performed in a computer apparatus, the invention thusalso extends to computer programs, particularly computer pro-grams on or in a carrier, adapted for putting the invention intopractice. The program may be in the form of source code, objectcode, a code intermediate source and object code such as inpartially compiled form, or in any other form suitable for use inthe implementation of the process according to the invention.The program may either be a part of an operating system, or bea separate application. The carrier may be any entity or devicecapable of carrying the program. For example, the carrier maycomprise a storage medium, such as a Flash memory, a ROM(Read Only Memory), for example a DVD (Digital Video/ Versa-tile Disk), a CD (Compact Disc) or a semiconductor ROM, an EP-ROM (Erasable Programmable Read-Only Memory), an EEPROM(Electrically Erasable Programmable Read-Only Memory), or amagnetic recording medium, for example a floppy disc or harddisc. Further, the carrier may be a transmissible carrier such asan electrical or optical signal which may be conveyed via elect-rical or optical cable or by radio or by other means. When theprogram is embodied in a signal which may be conveyed directlyby a cable or other device or means, the carrier may be consti-tuted by such cable or device or means. Alternatively, the carriermay be an integrated circuit in which the program is embedded,the integrated circuit being adapted for performing, or for use inthe performance of, the relevant processes.

The term “comprises/comprising” when used in this specificationis taken to specify the presence of stated features, integers,steps or components. However, the term does not preclude thepresence or addition of one or more additional features, inte-gers, steps or components or groups thereof.

The invention is not restricted to the described embodiments inthe figures, but may be varied freely within the scope of theclaims.
