This disclosure relates generally to the field of vehicular and other security, access, convenience, monitoring, and control products.
A vehicle control system (“VCS”) may be an OEM or an aftermarket electronic system installed in a vehicle for monitoring, security, and users' convenience and entertainment, as well as for other reasons. The functionality provided by such systems may include remote start capability, passive keyless entry, passive locking, and other security, convenience, entertainment, and monitoring features.
A need in the art exists for improved techniques for providing access to VCS-equipped vehicles without transferring a key, key fob, or analogous access device to another user of the vehicle. A need in the art exists for improved techniques for providing temporary and/or limited access to such vehicles, to the various features of such vehicles and their VCS's, and to various compartments of such vehicles. Other needs in the art will occur to a person skilled in the art after careful perusal of this disclosure (including any documents incorporated by reference), claims, figures, and all other matter filed together with this disclosure.
This document describes embodiments, variants, implementations, and examples of novel systems, methods, and articles of manufacture for addressing one or more of the needs identified above, and/or other needs. Selected embodiments described in this document include methods, apparatus, and articles of manufacture that enable improved techniques of sharing vehicles through sending and receiving mobile device messages, such as short message service (SMS) smartphone messages.
In embodiments, an apparatus includes a vehicle control system configured to couple to a computer of a vehicle via a vehicle bus of the vehicle and to control locking and unlocking of the vehicle. The vehicle control system includes one or more VCS processors, memory coupled to the one or more VCS processors and storing VCS software executable by the one or more VCS processors, a first short range radio frequency (RF) VCS transceiver coupled to the one or more VCS processors, and a smartkey power control module (SPCM) configured to provide to a smartkey of the vehicle electrical power selectively under control of the one or more VCS processors, thereby selectively allowing and preventing operation of smartkey-enabled features of the vehicle. The apparatus also includes a cloud-based vehicle control platform (VCP) configured to: send and receive Short Message Service (SMS) messages and control operation of the VCS; receive a first message from a first smartphone of an authorized user of the vehicle, the first message comprising identification of a second smartphone of a second user with whom the first user wishes to share the vehicle; in response to the first message, send a second message to the second smartphone, the second message informing the second user of availability of the vehicle for sharing; receive a third message from the second smartphone, the third message requesting access to the vehicle; validate the third message as coming from the second smartphone; and in response to the third message, send a signal the VCS to grant access to the vehicle.
In embodiments, a method of sharing vehicles includes receiving by a cloud-based system a first message from a first mobile device of an authorized user of a vehicle. The first message includes identification of a second mobile device of a second user. The method also includes sending a second message from the cloud-based system to the second mobile device, in response to the first message. The second message includes a welcome and information regarding availability of the vehicle for sharing. The method additionally includes receiving a third message by the cloud-based system from the second mobile device. The third message includes a request by the second user to access the vehicle. The method further includes validating the third message as coming from the second mobile device and, in response to successful validation of the third message, sending a grant access signal from the cloud-based system to a Vehicle Control System (VCS) installed in the vehicle. The grant access signal causes the VCS to allow access to the vehicle.
In embodiments, an article of manufacture includes a non-volatile machine-readable storage medium with program code stored in the storage medium. When the program code is executed by a cloud-based computing system, it causes the cloud-based computing system to receive a first message from a first mobile device of an authorized user of a vehicle. The first message includes an identification of a second mobile device of a second user. The program code also causes the cloud-based computing system to send a second message to the second mobile device in response to the first message. The second message includes a welcome and information regarding availability of the vehicle for sharing. The program code additionally causes the cloud-based computing system to receive a third message from the second mobile device. The third message requests access to the vehicle. The program code further causes the cloud-based computing system to validate the third message as coming from the second mobile device, and in response to successful validation of the third message, to send a grant access signal to a Vehicle Control System (VCS) installed in the vehicle. The grant access signal causes the VCS to allow access to the vehicle.
In embodiments, an apparatus for enabling sharing of vehicles includes a vehicle control platform (VCP) computing system coupled to a wide area network. The VCP is configured to receive a first message from a first mobile dev ice of an authorized user of a vehicle. The first message includes an identification of a second mobile device of a second user. The VCP is also configured to send a second message to the second mobile device in response to the first message. The second message includes a welcome and information regarding availability of the vehicle for sharing. The VCP is additionally configured to receive a third message from the second mobile device. The third message includes a request to access the vehicle. The VCP is further configured to validate the third message as coming from the second mobile device and send a grant access signal to a Vehicle Control System (VCS) installed in the vehicle in response to successful validation of the third message. The grant access signal causes the VCS to allow access to the vehicle.
Various features and aspects will be better understood with reference to the following description, drawings, and claims.
The words “embodiment,” “variant,” “example,” “implementation,” and similar words and expressions as used in this document refer to a particular apparatus, process, or article of manufacture, and not necessarily to the same apparatus, process, or article of manufacture. Thus, “one embodiment” (or a similar word/expression) used in one place or context may refer to a particular apparatus, process, or article of manufacture; the same or a similar expression in a different place or context may refer to a different apparatus, process, or article of manufacture. The expression “alternative embodiment” and similar words and phrases may be used to indicate one of a number of different possible embodiments, variants, examples, or implementations. The number of possible embodiments, variants, examples, or implementations is not necessarily limited to two or any other quantity. Characterization of an item as “exemplary” means that the item is used as an example. Such characterization does not necessarily mean that the embodiment, variant, example, or implementation is a preferred one; the embodiment, variant, example, or implementation may but need not be a currently-preferred embodiment variant, example, or implementation. All embodiments, variants, examples, and implementations are described for illustration purposes and are not necessarily strictly limiting.
The words “couple,” “connect,” and similar words/expressions/phrases with their inflectional morphemes, do not necessarily import an immediate or direct connection, but in addition to direct connections include within their meaning connections through mediate elements.
The expression “processing logic” should be understood as selected steps/decision blocks and/or hardware/software/firmware for implementing the selected steps/decision blocks. “Decision block” means a step in which a decision is made based on some condition, and subsequent process flow is selected based on whether the condition is met or not met.
A vehicle control system (VCS) may be an aftermarket or an OEM system installed in a vehicle to provide convenience, security, and monitoring features, such as security/alarm system functionality; passive keyless entry (“PKE”) and automatic passive action (“APA”) functionalities, including door unlocking and/or opening in response to a person carrying a key or a key fob of the vehicle touching or moving door/hatch handles, door locking and/or closing in response to the person carrying the key/key fob moving away from the vehicle; remote engine start; short-range radio frequency communications (Bluetooth® and other RF communication systems having similar range) with portable devices such as smartphones, smartwatches, tablets, smart implants, and still other devices; and similar functions. A VCS may be such as (or similar to, or having selected components of) the vehicle control systems described in the above-identified and incorporated by reference patent documents; and also in U.S. Pat. No. 10,249,182 entitled REMOTE VEHICLE SYSTEM CONFIGURATION, CONTROL, AND TELEMATICS, James S. Turner first-named inventor, which is incorporated herein by reference for all purposes, including specification, abstract, figures, claims, and all other matter.
A VCS installed in a vehicle may be connected to the Controller Area Network bus (“CAN bus”) of the vehicle, and interface/communicate with the vehicle's electronics/computer via the CAN bus. The VCS may also sense CAN bus communications between and among the vehicle's electronic components. Another type of bus interconnecting the vehicle's electronics may take place of the CAN bus, and the vehicle's VCS may similarly interface/communicate with the vehicle's electronics/computer via such bus, as well as sense communications of the vehicle's electronic components on such bus.
A “mobile device” (or simply a “mobile”) and “portable device” are used interchangeably, to signify smartphones, smartwatches, tablets, smart implants, portable computers, and similar portable devices. A mobile device typically includes a processing module (such as microprocessor(s), microcontroller(s), other programmable devices, and their memories and other supporting electronic components); a user I/O interface (such as a display/keyboard/touch-sensitive display); one or more transceivers (such as cellular transceivers, WiFi transceivers, Bluetooth® and other relatively short-range radio frequency transceivers); and other components.
A smart key and smart key fob may be referred to as “smartkey.” In typical use, the vehicle (vehicle computer, vehicle electronics) may send a signal (a “challenge”) to a smartkey, to determine whether a smartkey authorized to access/operate the vehicle is present inside the vehicle or in the immediate vicinity of the vehicle; when the smartkey responds (by sending a “challenge response”), the vehicle (vehicle computer/electronics) may allow engine start and/or operation of all or of selected convenience and security features, such as locking/unlocking the vehicle and the vehicle's various compartments (trunk, glove compartment, hood, etc.), and arming/disarming the vehicle's security system. The smartkey's response may be static or, more commonly, a result of a dynamic computation, e.g., to prevent smartkey spoofing. Some VCSs described in this and the incorporated documents may be configured to sense challenges, generate appropriate challenge responses (in the place of the smartkey), and send the challenge responses to the vehicle, thus simulating a smartkey's presence.
Some definitions have been explicitly provided above. Other and further explicit and implicit definitions and clarifications of definitions may be found throughout this document.
In embodiments, the VCS and or the smartkey of the vehicle are configured to make it appear to the vehicle's electronics/computer that the functionality associated with the smartkey's presence should be enabled. For example, the smartkey may be placed in the vehicle, and preferably secured so that it cannot be readily found and/or removed or tampered with. The smartkey may be secured, for example, in the enclosure of the VCS. The vehicle's electronics computer would then be able to sense the presence of the smartkey in the vehicle and allow engine start and/or operation of convenience, security, and/or other features that require an authorized smartkey of the vehicle to be inside or in the immediate vicinity of the vehicle (“smartkey-enabled features”). But the VCS connected to the vehicle's CAN bus (or another analogous type of a bus interconnecting electronics of the vehicle) may be configured selectively to prevent engine start and/or operation of the smartkey-enabled features. In this way, the security of the vehicle may be preserved despite the presence of the smartkey in the vehicle, because the VCS can selectively (under control of the VCS processor, through the bus) enable and prevent engine start and operation of the other smartkey-enabled features.
In embodiments, the VCS is configured to simulate selectively the presence of the smartkey in or near the vehicle, by receiving from the vehicle's electronics the smartkey challenges, and generating the appropriate challenge responses, to make it appear to the vehicle's computer that the smartkey is present in or near the vehicle. For example, the VCS can receive the challenges from the CAN or analogous bus, and return appropriate challenge responses, also through the bus. In another example, the VCS may be connected through a transceiver to the antenna that the vehicle's computer/electronics use to transmit the smartkey challenges and receive challenge responses. The VCS may interpret the challenges actually sent by the vehicle electronics to the smartkey, unlike sensing the challenges through the bus. (The “antenna” here includes the wire connected to the antenna proper.) The VCS may then selectively (under control of the VCS processor) generate appropriate challenge responses to simulate the presence of the smartkey in/near the vehicle, and drive the antenna with these challenge responses. As has already been mentioned, the challenges and/or the responses may be static or dynamic; a dynamic response varies from time-to-time, location-to-location, challenge-to-challenge, and/or otherwise; the VCS and/or the mobile device of a user have (or can obtain) information for determining/computing an appropriate response to a challenge, for example, in the same way as the vehicle's smartkey would.
In embodiments, the VCS includes a smartkey power control module for the smartkey of the vehicle. The smartkey receives the electrical power for its operation when the VCS (under control of the VCS processor) determines that the operation of the smartkey-enabled features is allowed and/or required, and configures the smartkey power control module so that the smart key is energized. The smartkey power control module may be an electrically-operated switch such as an electromechanical or a solid state relay; it may be placed, for example, in series with the battery contacts (power inputs) of the smartkey. When the smartkey power control module, under control of the VCS processor, turns on the power to the smartkey in the vehicle, the vehicle electronics sense the smartkey's presence and allow operation of the smartkey-enabled features. The smartkey may be, for example, secured to the vehicle and/or be placed inside the enclosure of the VCS or one of the modules of the VCS, to make unauthorized removal difficult. The VCS is configured to turn the power to the smartkey on when needed to operate any of the smartkey-enabled features, such as the panic command, engine start, door lock/unlock, security features enable/disable and arm/disarm, and others.
The VCS 100 includes a bus 105, a processing module 107, a memory/storage module 109, an interface or interfaces 110 to vehicle systems (e.g., door locks, power windows, entertainment system, alarm, and others), a remote start module 115, an add-on security module 120, a relatively short range RF communication interface/transceiver(s) 125 to external devices, a smartkey power control module (SPCM) 130 configured to provide selectively electrical power to a smartkey 140, and additional RF transceiver(s) 127 for communicating with cloud-based hardware/software modules 180. The smartkey 140 may be considered port of the VCS 100, or a separate component, and may be placed inside the enclosure of the VCS 100 or outside the enclosure.
The bus 105 may be as a processor-based system bus that provides communication/networking capability between and among the components of the VCS 100. The processing module 107 may include, for example, a microprocessor/microcontroller and supporting electronics. The memory/storage module(s) 109 can store instructions executable by the processing module 107; the memory/storage module(s) 109 may include one or more memories of same or different types, such as ROMs, PROMs, EPROMS, EEPROMS, flash memories, optical disks, magnetic storage devices, and/or other memories-storage. The memory/storage module(s) 109 may also include volatile memory module(s) such as DRAM modules, which may be battery backed.
The interface or interfaces 110 may connect to an engine computer (engine control module or ECM); a transmission computer (transmission control module or TCM); built-in vehicle firmware; built-in security features of the vehicle; a telematics module; and data storage for data that includes the vehicle's usage and performance data, such as OBD II data. The interface 110 may be a CAN bus interface.
The remote start module 115 allows starting of the vehicle by the VCS 100, in response to appropriate commands, for example, remote start commands received from a user mobile device 150. The remote start module 115 may also interact with the vehicle control modules through the interfaces 110 accessible to the remote start module 115 through the bus 105.
The add-on security module 120 may connect to and monitor various sensors (e.g., shock/vibration, proximity, intrusion, door or other entry point touch sensors/controls that indicate when the user is trying to open the entry point for access to the vehicle), and may operate and/or sense state of and/or control various convenience features (e.g., power windows, power locks, power seats, steering wheel telescoping and tilt positions, audio system presets and other audio system controls).
The relatively short range RF communication transceiver(s) 125 may include, for example, a Bluetooth® interface. The transceiver(s) 125 may also be or include other types of RF interfaces. Moreover, multiple relatively short range RF transceivers may be included. Thus, a first transceiver and a second transceiver may be included, the first transceiver 125 having a shorter communication range than the second transceiver. For example, the transmit power of the first transceiver 125 may be less than the transmit power of the second transceiver 125 by a factor of 2-20, with the two transceivers 125 being of the same type (such as Bluetooth®) or of different types. The first transceiver 125 may be, for example, a Bluetooth® Low Energy transceiver, while the second transceiver 125 may be a non-LE Bluetooth® transceiver.
The transceiver(s) 127 may include a cellular transceiver providing to the VCS 100 access to a cellular telephone/data network and other networks, such as the Internet and the cloud-based modules 180.
Although the link 155 is shown as a unidirectional link, in variants it is bidirectional, allowing the cloud-based modules 180 to send messages/information to the first user mobile device 150. The link 105 is shown as a bidirectional link, but in variants it may be a unidirectional link, from the cloud-based modules 180 to the VCS 100, allowing the cloud-based modules 180 to control and send information to the VCS 100. Note, however, that additional links may be present, for example, between the mobile devices 150/160, and between the mobile device 150 and the VCS 100. (The listing of links is not exclusive.)
Here, the cloud-based modules 180 include a Vehicle Control Platform (VCP) 182, which may include a set of cloud services used to relay data and commands to/from vehicles, and manage vehicle accounts, as well as other services functions. In embodiments, the VCP 182 may expose application programming interlaces (“API”s) to grant and revoke sharing privileges; expose the APIs to send commands to vehicles; validate authority of a user invoking the APIs; and invoke an AWS Pinpoint 186 (discussed below) to send an initial welcome message and/or other messages to the first user and other users of the system.
The cloud-based modules 180 may also include AWS Lambda 184, which can execute functions provided by clients as a service (“Function as a Service” or “FaaS”). In embodiments, AWS Lambda 184 may receive an SMS payload, validate command(s), retrieve an asset such as a vehicle shared with a sender's SMS number, validate time period for which the asset is shared; access APIs of the VCP 182 to send command(s) to the vehicle, and reply to a sender with SMS messages indicating, e.g., success, failure, or access denied.
The cloud-based modules 180 may additionally include the AWS Pinpoint 186, which module(s) is/are capable of sending personalized, timely, and relevant communications through multiple channels. In embodiments, AWS Pinpoint 186 may provide dedicated long codes (e.g., SMS numbers), send SMS messages to end users originating from dedicated long codes, receive SMS messages sent from end users to dedicated long codes, and invoke an SNS Topic 188 when an SMS message is received.
The SNS Topic 188 of the cloud-based modules 180 is an AWS simple notification service. In embodiments, the SNS Topic 188 notifies the AWS Lambda 184 of SMS message(s) from the AWS Pinpoint 186.
As is illustrated in
Note that AWS is used for illustration, and other services and proprietary systems may be used. Similarly, the specific architecture of the cloud-based modules in
In operation, the cloud-based modules 180 and the mobile device 150 executing the SmartAssetSharing app may be configured to enable vehicle sharing through the use of SMS or other messages.
At flow point 401, the first user mobile device 150 (with the SmartAssetSharing app installed) and the second user mobile device 160 are powered up and ready for operation, and the cloud-based modules 180 have been properly configured and are also ready for operation. Further, the VCS 100 is installed, properly configured, and powered up at this point.
In step 405, the app on the first user mobile device 150 is activated (e.g., by tapping the SmartAssetSharing app icon) and presents to the first user a menu with a selection of vehicles for sharing. As noted above, the first user mobile device 150 may enable access/sharing of more than one vehicle, though this is not a requirement. From the menu, the first user selects a vehicle for sharing (e.g., by tapping in appropriate places on the screen of the user's mobile, as may be the case with other selections and inputs made by the first and second users). In response to the vehicle selection, the app may present to the first user one or more sharing parameters, and the first user may choose value(s) for the parameter(s) and input the value(s) into the app. For example, the first user may specify sharing start time, sharing end time, sharing duration, and the phone number of the second user mobile device 160. As will be seen, the VCP 182 may use the number of the second user mobile device 160 for messaging and identification/Verification of the permission for the second user to use the selected vehicle.
In step 410, the first user mobile device 150 transmits to the VCP 182 a “sharing indication” message indicating dial the second user at the number of the second user mobile device 160 is authorized to use the vehicle; the message may include any of the parameters for sharing, particularly the number of the second user mobile device. (The messages from/to mobile devices described in this document may be SMS or analogous messages.)
In step 415, the VCP 182 receives the sharing indication, stores the sharing indication, and processes it, e.g., extracting the second mobile number and other parameters for sharing.
In step 420, the VCP 182 sends a welcome message to the second user mobile device, which message may also include other data and instructions relating to sharing of the vehicle. For example, the message may include the following text:
In step 425, the second user at the second user mobile device 160 receives the welcome message and sends a reply to the welcome message, for example, “UNLOCK.”
In step 430, the VCP 182 receives the reply and validates the reply (e.g., verifies the phone number from which the reply was sent). The VCP 182 may do this, for example, by comparing the number of the phone from which the reply was sent to the number in the sharing indication; in embodiments, a password or analogous authentication may also be included in the sharing indication and used for verification of the second user and the second user mobile device 160.
If the validation is successful (e.g., the numbers match, password is correct), in step 435 the VCP 182 sends a message (instruction/command) to the VCS of the selected vehicle, to cause the VCS to unlock the vehicle and grant access to the second user. The VCS may grant access by energizing the smartkey 140 through the SPCM 130.
In step 440, the VCS receives the instruction/command from the VCP 182 and acts upon it, unlocking the vehicle and granting access to the second user at the second user mobile device 160. The VCS may grant access by configuring the SPCM 130 to energize the smart key 140 in the vehicle. The VCS ma also be configured to confirm that the second user mobile device is sufficiently near the selected vehicle, before unlocking the vehicle and granting access.
In step 445, the cloud-based modules 180 may send one or more messages to the first user mobile device 150 and/or the second user mobile device 160, confirming that the requested action (e.g., unlocking, granting access) has been carried out.
The process flow may then terminate at How point 499, to be repeated as needed or desired.
The second user may send to the VCP 182 another reply message, such as FLASH or HONK, and the VCP 182 may then validate the second user mobile device number, signal the VCS to perform an action corresponding to the reply message (e.g., honk the horn/siren, flash headlights). Selected steps of this example are illustrated on the right side of
At flow point 501, the first user mobile device 150 and the second user mobile device 160 are powered up and ready for operation, the cloud-based modules 180 have been properly configured, and sharing of the vehicle has previously been initiated, for example, as described in relation to the process 400.
In step 505, the second user at the second user mobile device 160 sends to the VCP 182 a predetermined message indicating that the second user wishes to terminate sharing, for example, “LOCK.”
In step 510, the VCP 182 validates the second user mobile device number. This may be similar to the step 430 of the process 400. In embodiments where a password or analogous authentication information was included in the sharing indication, the password or information may also or instead be used for verification.
If the validation is successful, in step 515 the VCP 182 sends to the VCS a message to terminate access of the second user (second user mobile device 160) and lock the vehicle (this message may be referred to as a “sharing termination message”).
In step 520, the VCS receives the sharing termination message from the VCP 182, locks the vehicle, and terminates access grant. The access grant may be terminated, for example, by disabling/de-energizing the smartkey in the vehicle, and/or by configuring the VCS not to provide access or perform other functions in response to the VCS sensing proximity of the second user mobile device 160.
In step 525, one or more messages may be sent to the first user mobile device 150 and/or the second user mobile device 160, confirming termination of sharing of the vehicle. The VCP 182 may send these messages.
The process flow may then terminate at flow point 599, to be repeated as needed or desired.
The sharing of the vehicle may also be terminated in response to other events, for example, automatically, when the time/period of sharing (parameters mentioned above) expire, when the first user sends a message to the VCP 182 through the SmartAssetSharing app (making a call to the VCP API, e.g., from the first user mobile device 150 or another authenticated device) to terminate sharing, or in response to some other condition(s) for terminating sharing being met.
The processes and apparatus for sharing described in this document may be used with vehicles such as cars, boats, planes, golf carts, ATVs, RVs, snowmobiles, and others. The processes and apparatus may also be adapted to enable sharing of other assets, whether movable or not movable, including real estate assets such as dwellings, offices, warehouses, and others.
