Systems and programs for managing personalized settings in a mobile vehicle are also provided.

## Background
FIELD OF THE INVENTION
This invention relates generally to personalized settings in a mobile vehicle communication system. Specifically, the invention relates to a method and system for persisting personalized settings in a mobile vehicle using a mobile vehicle communication system, particularly during a period of vehicle maintenance.
BACKGROUND OF THE INVENTION
Maintenance and repair are necessary during the life of a mobile vehicle in order to keep the vehicle functioning properly. Each operational system of a mobile vehicle is generally controlled by a specific electronic control, referred to as a “module.” Some examples of operational systems include body control system, radio control system, remote function activation (RFA) system and the heating, ventilating and air conditioning (HVAC) system. Maintenance and repair of a given operational system therefore, may also involve working with the electronic control module for that system. In some instances, a module may be determined to be bad. Repair is accomplished by replacing the bad module.
Currently, if the bad module keeps settings that have been personalized, these setting are lost once the bad module is replaced with a new module. In some cases personalization settings are irretrievable when communication cannot be established with a module. It is desirable for customer satisfaction to keep many of these settings as they were before the vehicle repair. For example, some typical personalized settings in the body control module (BCM) include a setting for the length of time that the light on is delayed (i.e., delay light for 30, 60 or 90 seconds) and settings for when doors should be locked or unlocked (i.e. unlock doors when vehicle is in park or lock doors when vehicle is at a certain speed or lock doors according to child proof lock settings). Other settings include preferred radio stations, current local time, equalization, fade, treble level and bass level in the radio control module. Other personalized settings include preferred settings for the RFA such as door lock personalization settings (e.g. unlock one door or all doors) and automatic positioning settings for the driver's seat. Clock settings and compass calibrations for the customer's region are other examples of personalized settings that may be lost with replacement of a bad module.
The repair service and/or dealer must then manually reset whatever settings can be reset. In some cases, the customer loses all personalized settings. Furthermore, in some cases, the personalized settings are irretrievable when communication cannot be established with a particular module.
Certain settings, such as vehicle safety settings, theft protection settings and driving operation control settings, are stored in secured memory. These settings persist whatever module is replaced. However, secured memory is limited and expensive and is used for the vital settings detailed above. Little or no secured memory is left to store personalized vehicle settings.
Accordingly, it would be desirable to have a system and method for managing and persisting personalized settings in a mobile vehicle using a mobile vehicle communication system. It would be desirable to implement this system and method at the time of vehicle maintenance
It is an object of this invention, therefore, to provide a method for persisting personalized vehicle settings at the time of vehicle maintenance, and to overcome the obstacles described above.
SUMMARY OF THE INVENTION
One aspect of the invention is a method of managing personalized settings in a mobile vehicle, particularly during service replacement of a vehicle module. The personalized settings currently stored in the vehicle module are determined. The settings are first stored at a vehicle settings storage unit and later transferred to a replacement module. A telematics module may communicate with the vehicle module to determine the personalized settings. A predesignated memory location for the personalized settings in the vehicle module may also be determined and the settings may later be transferred to a matching predesignated memory location in the replacement module. Alternatively a new value of the personalized settings may be entered and transferred to the matching predesignated memory location. Identifying parameters of the vehicle module to be re-set may be determined for proper matching.
Another aspect of the invention is a system for managing personalized settings in a mobile vehicle, particularly during service replacement of a vehicle module. The system includes means for determining personalized settings stored in the vehicle module, means for storing the personalized settings at a vehicle settings storage unit and means for transferring the personalized settings to a replacement module. The system may also include means for communicating with the vehicle module via a telematics unit to determine the personalized settings. The system may also include means for determining a predesignated memory location for the personalized settings in the vehicle module and means for transferring the personalized settings to a matching predesignated memory location in the replacement module. The system may further include means for entering a new value of the personalized settings as well as means for transferring the new value of the personalized settings to the replacement module. The system may further include means for determining identifying parameters of the vehicle module.
Yet another aspect of the invention is a computer usable medium including a program to manage personalized settings in a mobile vehicle particularly during service replacement of a vehicle module. The program includes computer program code that determines personalized settings stored in the vehicle module, computer program code that stores the personalized settings at a vehicle settings storage unit and computer program code that transfers the personalized settings to a replacement module. The program may also include computer program code that communicates with the vehicle module via a telematics unit to determine the personalized settings. The program may also include computer program code that determines a predesignated memory location for the personalized settings in the vehicle module and computer program code that transfers the personalized settings to a matching predesignated memory location in the replacement module. The program may further include computer program code that enters a new value of the personalized settings as well as computer program code that transfers the new value of the personalized settings to the replacement module. The program may further include computer program code that determines identifying parameters of the vehicle module.
The aforementioned and other features and advantages of the invention will become further apparent from the following detailed description of the presently preferred embodiments, read in conjunction with the accompanying drawings.

FIGS. 2a through 2c illustrate a vehicle settings management (VSM) system 200 in accordance with another embodiment of the current invention. The components shown in FIGS. 2a through 2c may also be used in conjunction with one or more of the components of mobile vehicle communication system 100, above.
VSM system 200 includes a vehicle network 112 and telematics unit 120 as well as one or more of their separate components, as described above. VSM 200 further comprises a vehicle settings control unit (VSCU) as well as a vehicle settings storage unit (VSSU).
As seen in FIG. 2a, both VSCU 224 and VSSU 234 may be resident in telematics unit 120. As seen in FIG. 2b, VSCU 224 and VSSU 234 may also be in wireless or wired communication with telematics unit 120, while remaining physically separate from telematics unit 120. For example, VSCU 224 and VSSU 234 may reside at call center 170. As seen in FIG. 2c, VSCU 224 and VSSU 234 may be resident in MVCU 110 as their own separate module. Such a module could be in communication with telematics unit 120 via vehicle network 112. VSCU 224 may be connected as one unit with VSSU 234 as seen in FIGS. 2b and 2c or may be separated from, but in communication with, VSCU 234.
VSCU 224 is any suitable processor for receiving and managing data from VSSU 234 and telematics unit 120 and/or various components of telematics unit 120. VSCU 224 executes various computer programs that may read, process and store information such as the programming and operational modes and settings of electronic and mechanical systems within a given vehicle module.
In one embodiment of the invention, repair personnel uses telematics unit 120 to communicate with VSCU 224 and indicate that a vehicle module will be replaced. VSCU 224 through telematics unit 120 receives additional information about the specific vehicle module, such as parameters that describe the specific vehicle module. These parameters include the mobile vehicle's make, model, year and a name of the module. VSCU 224 processes these parameters to determine the memory locations for personalized vehicle settings in the specific vehicle module. VSCU 224 then controls scanning and downloading of the settings data at these locations. VSCU 224 also controls scanning uploading of settings data at memory locations in the replacement module.
VSSU 234 is any suitable location for storing information processed by VSCU 224. Such information includes, but is not limited to, programming and operational modes and settings of electronic and mechanical systems within one or more vehicle modules, parameters describing vehicle modules (such as the examples listed above), specific memory locations within one or more vehicle modules and information necessary for VSCU 224 to function appropriately.
FIG. 3 illustrates a method 300 of persisting personalized vehicle settings in a mobile vehicle communication system in accordance with one embodiment of the current invention. Although the steps described in method 300 are shown in a given order, the steps are not limited to the order illustrated. The method 300 may be performed, for example, when a vehicle is brought in for repair, before a bad module is removed from the vehicle.
As seen at block 310, VSCU 224 receives a signal that the offloading of personalized settings data from a given vehicle module is desired. This signal may be sent to VSCU 224 via telematics unit 120. In one embodiment, repair personnel press a button on telematics unit 120 to initiate communication with VSCU 224.
As seen at block 315, VSCU 224 sends parameters describing the vehicle via telematics unit 120. Such parameters include the mobile vehicle's make, model, year, a number identifying the vehicle (Vehicle Identification Number or VIN) and a name of the module to be replaced. These parameters may be sent, for example, to call center 170 to help identify the vehicle and module. These parameters may be used, as detailed below, in order to process and persist the personalized settings properly.
As seen at block 320, VSCU 224 determines predesignated memory locations for the given vehicle module. These predesignated memory locations may be determined using parameters such as the mobile vehicle's make, model, year and a name of the module to be replaced. The predesignated locations may have been designated for storage of personalized settings at the time of the vehicle's creation. In one embodiment, repair personnel send such parameters to VSCU 224 via telematics unit 120. VSCU 224 may also communicate with call center 170 to help determine the proper predesignated memory locations for a given module and/or vehicle. These parameters may be determined, for example, by reviewing written information regarding the module in question. Such written information may be sent to VSCU 224 for determination from call center 170 or from other appropriate locations within mobile vehicle communication system 100.
As seen at block 330, VSCU 224 then scans these predesignated locations for personalized data. VSCU 224 may accomplish this, for example, by reading the locations that have been identified at step 320.
As seen at block 340, VSCU 224 then determines if there is data at a predesignated location.
As seen at block 350, if VSCU 224 finds data at a pre-designated location, VSCU 224 proceeds to process the personalized settings data, for example by downloading the data for storage to VSSU 234.
As seen at block 345, if VSCU 224 does not find data at a pre-designated location, VSCU 224 moves on to the next pre-designated location. Steps 330, 340, 345 and 350 may be repeated until all pre-designated locations determined at block 310 have been examined for personalized settings and all personalized settings have been downloaded to VSSU 234.
FIG. 4 illustrates a method 400 of persisting personalized vehicle settings in a mobile vehicle communication system in accordance with another embodiment of the current invention. Although the steps described in method 400 are shown in a given order, the steps are not limited to the order illustrated. The method 400 may be performed, for example, after a vehicle has been repaired, when a replacement module has already been placed in the vehicle. Repair personnel may initiate the method 400 while the vehicle is still at the repair facilities. Alternatively, the owner of the vehicle may also initiate the method 400 at any time after the module has been replaced, for example, after having driven the vehicle home.
As seen at block 410, VSCU 224 receives a signal indicating that a process of re-setting personalized vehicle settings should be initiated for a particular vehicle module that has now been replaced. This signal may be sent to VSCU 224 via telematics unit 120. In one embodiment, repair personnel press a button on telematics unit 120 to initiate communication with VSCU 224. Alternatively, the client may initiate communication with VSCU 224.
As seen at block 415, VSCU 224 matches the vehicle module to be re-set with the settings from the previous/replaced module. VSCU 224 may accomplish this for example by communicating with call center 170 via telematics unit 120. For example, call center 170 may provide VSCU 224 with a list of recently replaced vehicle modules and their associated saved settings. Thus, the user may choose the module for which personalized settings should be re-loaded/re-set. Alternatively, VSCU 224 may send vehicle parameters describing the vehicle module to be re-set via telematics unit 120. Such parameters include the mobile vehicle's make, model, year, a number identifying the vehicle (Vehicle Identification Number or VIN) and a name of the module to be replaced. These parameters may be sent, for example, to call center 170 to help identify the vehicle and module. These parameters may be used, as detailed below, in order to re-set the desired personalized settings.
As seen at block 420, VSCU 224 determines pre-designated memory locations for the replacement module. These pre-designated memory locations may be determined using parameters such as the mobile vehicle's make, model, year and a name of the module to be replaced. The pre-designated locations may have been designated for storage of personalized settings at the time of the vehicle's creation or may be based on the pre-designated locations of the previous vehicle module that was removed (determined, for example at step 320 of method 300 above.) In one embodiment, repair personnel send such parameters to VSCU 224 via telematics unit 120.
As seen at block 430, VSCU 224 then receives the first personalized settings data packet. This data may be, for example, specific personalized data stored in VSSU 434. Such data may have been stored at step 350 of method 300 above.
As seen at block 440, VSCU 224 then matches the first personalized settings data packet to a first pre-designated memory location. That is, VSCU 224 determines a memory location in the replacement module and checks if the data may be matched to that location. For example, VSCU 224 may find the memory location for radio station preferences at a first location and the memory location for lights off settings at a second location at block 410. VSCU 224 may then receive a data packet at block 430 that comprises the previous radio station preferences. At block 440, VSCU 224 matches the data packet to the found radio station preferences at the first memory location.
If the data packet does not match the found memory location, the process may then abort or re-start. For example, if VSCU 224 finds the memory location for radio station preferences at block 410 and then receives a data packet at block 430 that comprises the previous lights off settings, the technician may have installed an incorrect component. Saving the wrong data packet to the wrong predesignated location may cause undesirable results.
As seen at block 450, once the data packet is matched to its proper pre-designated memory location, VSCU 224 sends a signal requesting confirmation of the personalized data settings stored in the packet. VSCU 224 may send this signal, for example, to telematics unit 120. The user may use telematics unit 120 to confirm that the data is correct and should be kept.
As seen at block 460, if the user confirms the data, VSCU 224 writes the personalized settings data packet to the first pre-designated location.
As seen at block 455, if the user wishes to change the value of the settings, the user may enter new personalized data settings (e.g. change the lights off time setting to 30 seconds instead of 60). The user may enter the new settings via telematics unit 120. The method 400 may then proceed to block 460 where VSCU 224 writes the changed settings to the first pre-designated memory location.
Steps 440, 450, 355 and 460 may be repeated until all data packets have been matched to appropriate predesignated memory locations in the replacement module.
While the embodiments of the invention disclosed herein are presently considered to be preferred, various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is indicated in the appended claims, and all changes that come within the meaning and range of equivalents are intended to be embraced therein.
