The present invention relates in general to home and vehicle security and safety, and, more specifically, to a home automation/smart assistant interfacing with a transport vehicle when monitored events occur.
As the Internet of Things (IoT) continues to expand, more and more devices are connected to the internet including smart smoke alarms, house security alarms, CO detectors, doorbells, sump pump/flood alarms, and others. This usually requires older alarm units in the home to be exchanged for a smart version of the device that has some communication capability either directly to the internet or to another device that is connected to the internet, in order to alert the homeowner or authorities that the alarm device has triggered. These smart alarm devices are normally increased in cost compared to the unconnected or non-smart version they are replacing. The investment by a homeowner or business owner for these new devices can be a significant cost. Many dwellings, offices, and other fixed locations may now have a smart listening device (SLD) installed which functions as a “virtual assistant” in the form of a voice-controlled wireless speaker with an electronic interface to a cloud service and local peripherals. Example devices include the Amazon Echo and the Sonos One (both of which use Amazon's Alexa Voice Service) and Google Home (which uses Google Assistant). These devices are being used to connect to a proliferation of smart home devices including Wi-Fi enabled smart alarm devices. While the smart alarm devices may usually communicate remotely with a user or an emergency services provider when a monitored event (e.g., smoke, carbon monoxide, or an intruder) is detected, an interface with the SLD can centralize and coordinate responses while increasing the detection and response capabilities.
The listening capabilities of an SLD can also enable a centralized/coordinated response to alarm devices which lack Wi-Fi or other remote capabilities. For example, an SLD can be trained to recognize the alarm sounds produced by non-networked alarm devices such as smoke alarms and to perform a desired notification or other response when the alarm sounds are detected. For training, a user can initiate an SLD programming mode via a button press or a voice command. With the SLD listening, the user manually triggers an alarm device (e.g., a doorbell or a smoke/carbon monoxide alarm) to emit its normal alerting sound. The SLD stores acoustical signatures in memory according to “tags” or label names as provided by the user. Any events with a sufficiently distinct acoustic signature could be recorded, labeled, and assigned to a responsive action. Example event triggers include security alarms, smoke detector, doorbell, CO alarm, knocking on an exterior door, a baby crying, sump pump shutoff or flood/high water audible alarms, unauthorized entry or attempted entry, garage door or entrance door opening, window glass breaking, dog barking, floor squeaks, unrecognized voice (based on prior voice training), sound of running water (e.g., broken pipe), or running appliances (e.g., microwave, dishwasher, clothes washer, or dryer). Multiple SLDs in the home may be used in coordination to identify the location of the sound within the home through various triangulation techniques.
During a monitoring mode, the SLD can continuously listen for sounds and compare collected audio samples against the signatures stored in memory. The monitoring mode may be initiated by the user through voice commands, by setting a schedule, or by conditions (such as lack of sound for a period of time) that indicate that the user is not home, for example. Once a particular match is detected with a stored signature, a corresponding alerting action or other response can be taken automatically. These can include a notification sent to the user or other contacts as identified in advance using a contact method also configured in advance (e.g., a network push notification). Other actions can include using the SLD to generate a sound (e.g., a barking dog) or activating Wi-Fi-enabled lights to frighten away a possible intruder.
The invention extends the alert/response capabilities of an SLD in novel ways which are cost efficient and provide significant improvements in safety and convenience.
In one aspect of the invention, a smart listening device comprises an audio detector responsive to speech and ambient sounds to provide digital audio signals. A distributed controller is coupled to the audio detector to execute responsive actions in response to the digital audio signals. A communications circuit establishes a first communication link with a backend. A vehicle database identifies at least one user transport vehicle and at least one responsive action corresponding to the user vehicle. The distributed controller has a monitoring mode for detecting preconfigured alerting events and has an alert/response mode for executing responsive actions associated with the detected alerting events. The communications circuit establishes a second communication link with the user vehicle when an executed responsive action is associated with a detected alerting event corresponding to the user vehicle in order to initiate the responsive action.
Voice-controlled smart assistant systems which communicate with a backend system in order to deliver relevant information via synthesized voice signals or prerecorded media content and to initiate other actions such as controlling peripheral electronic devices are becoming increasingly popular. In some embodiments, a wakeword or activation sound is detected by the smart listening device, which then interprets/analyzes the incoming audio. In regard to speech control, a device constantly listens for a wakeword but is otherwise inactive. For alarm detection, a recognized audio signature may be acted upon without recognition of the wakeword.
In
In the present invention, SLD 10 achieves expanded functionality and capabilities by interacting with a transport vehicle 30. Vehicle 30 may be a car, SUV, or truck of the same individuals who are residing in dwelling 25, for example. Vehicle 30 has an electrical system wherein various modules interact via a communication bus 31. By accessing devices on bus 31, the invention can obtain access to a wide variety of features and functions of vehicle 30 that may be useful in implementing actions and responses under control of SLD 10 in response to various preprogrammed events or alerts. Vehicle 30 may preferably include a Wi-Fi module 32 connected with bus 31 via a gateway (not shown) in order to establish a second communication link via Wi-Fi between SLD 10 and vehicle 30 (e.g., through Wi-Fi router 26). Vehicle 30 may also include a Bluetooth node 33 and a cellular transceiver 34 which could also support a communication link with SLD 10, depending upon the distance between vehicle 30 and SLD 10. Via the established communication link, many useful actions or responses become available in connection with various triggering events detected at SLD 10 as described below.
Vehicle 30 may typically include a remote keyless entry/security system (RKE) module 35 which receives RF signals from a remote key fob to control vehicle access and which can generate panic alarms and intrusion alarms by flashing vehicle lights and honking a vehicle horn, for example. When a monitored event is detected within dwelling 25 (whether directly detected by SLD 10 or by another smart device in communication with SLD 10) the affected area over which an alarm might be heard or noticed can be significantly increased by utilizing RKE system 35 of vehicle 30 to generate additional warning signs and sounds. As a result of conducting the necessary set-up within vehicle 30 and SLD 10 to allow a communication link and proper authentication between them (e.g., via Wi-Fi router 26 or Bluetooth node 33), SLD 10 can execute a responsive action comprising the triggering of audible and visible vehicle alarms when SLD 10 detects a preconfigured alerting event that has been set-up to include that action.
SLD 10 may be interconnected with various accessories 36 which may include various smart sensors or smart alarm systems for detecting various conditions such as smoke or carbon monoxide and which may generate their own warnings or may interact with SLD 10 to generate alerts and other responses. Accessories 36 may also include additional wireless interfaces configured to interact with RF controlled systems in the vehicle such as RKE system 35. In other words, a transmitter of the type used in a vehicle key fob can be incorporated into an accessory unit 36 or built into SLD 10 which sends the normal RF command signals used by vehicle 30 (e.g., by issuing a panic alarm command to RKE module 35). In addition accessories 36 may be used to recognize and relay an alarm condition occurring in the vehicle to the SLD to further extend the usefulness of the SLD to respond to vehicle conditions in situations where the audible recognition of the vehicle alarm is impaired.
Responsive actions executed by vehicle 30 can take many other forms by interacting with other vehicle systems such as a body control module (BCM) 37, an audio system 38 and loudspeaker 39, or a graphical display 40. For example, BCM 37 (or another module) can trigger an automatic cellular telephone call via cellular transceiver 34 to a remote assistance center or an emergency response provider. An automatic telephone call by the vehicle can be initiated in conjunction either with an audible alarm (generated by SLD 10 and/or vehicle 30) or without an audible alarm (e.g., a silent alarm that may have been generated by SLD 10 upon recognition of a “not safe” word spoken by a person facing an emergency in the dwelling, such as a home invasion). In another embodiment, the responsive action is comprised of notifying a user that an alerting event has been detected (e.g., by displaying a message on display 40 and/or synthesizing a voice message via audio system 38). As part of a notification, a two-way communication channel (e.g., an audio intercom) can be initiated between vehicle 30 and SLD 10 utilizing the communication link, thereby allowing the user in vehicle 30 to monitor an ongoing situation being detected by SLD 10 within dwelling 25.
In another embodiment, the vehicle 30 can be used as a device for collecting evidence when it is parked nearby dwelling 35 where a monitored event has been detected. For example, vehicle 30 includes forward and rearward cameras 41 and 42 which can be triggered to collect video signals to be recorded in a memory 43 which might capture events transpiring near dwelling 25 during a time of potential emergency. The recorded video could be later accessed in event reconstruction. The recording function may interact with a navigational GPS system 44 in order to tag recorded data with a geographic location and a time of day.
Vehicle 30 can also fulfill the role of a remote sensor (e.g., environmental sensor) to assist SLD 10 in evaluating various conditions being monitored. For example, a powertrain control module (PCM) 45 could be accessed in order to provide temperature data or humidity data used by SLD 10 to recognize alert conditions or select the best response to detected events. Other vehicle modules could also provide access to other important conditions, such as a body control module providing a vehicle security alarm trigger.
In connection with the ability of the invention to execute responsive actions associated with a transport vehicle, SLD 50 includes a set-up mode or block 60 used to configure a vehicle database 61 for storing identifying information and event parameters that are used in executing vehicle responsive actions. A user accesses set-up mode 60 to configure database 61 with link data for establishing communication links to one or more vehicles and to configure database 61 with feature data for each vehicle which enables various vehicle interactions supporting the responsive actions desired by the user. For example, protocols would be established for accessing and authenticating various system functions within the vehicle such as turning on or off a panic alarm, activating camera recording for a particular length of time, or activating the streaming one-way or two-way communication signals. The vehicle feature data may include identification of available features and selectable parameter settings that may be available such as camera views to be recorded, etc.
SLD 50 includes a monitoring block 62 which continuously listens for preconfigured acoustic signatures and waits for alarm notifications from associated smart sensors. When a monitored event is detected, then an alert response mode 63 is accessed by controller 54 for generating the preconfigured responsive actions.
In step 67, one or more vehicle links and vehicle feature data are set-up by the user. The communication links may be specified according to the available communication channels (e.g., Wi-Fi network, RF transmitter frequency, Bluetooth pairing, etc.), address information, and authentication credentials, for example. In step 68, responsive actions and alerts are configured for each potential alerting event associated with an identified vehicle so that they can be stored in the vehicle database within the SLD.
The registration of individual vehicles within database 61 can also be used in connection with activating and deactivating the monitoring mode. This feature can also benefit from an expansion of the database to include registration of the identities (and communication links) of persons who are authorized occupants of the home. As shown in
A person 75 occupies vehicle 70, and persons 76, 77, and 78 occupy vehicle 72. Vehicles 70 and 72 and people 75-78 and associated communication links are previously registered within a database in SLD 30. When all of people 75-78 are outside of zone 74, then SLD 30 can infer that dwelling 25 is unoccupied, and the absence of vehicles 70 and 72 from dwelling 25 can be helpful in determining the absence of the persons occupying them. For example, vehicles 70 and/or 72 can report their geographic coordinates to SLD 30 which then detects that vehicles 70 and/or 72 are outside zone 74. Each vehicle may identify its occupants (e.g., through various means of in-vehicle identification, such as phone pairing, voice-matching, facial recognition, or other biometric identification) and report this information to SLD 30. If all people who were previously registered to SLD 30 (e.g., all authorized occupants of a home) are found to be occupying a vehicle outside zone 74, then SLD 30 detects that dwelling 25 is now empty and it initiates the monitoring mode automatically. Similarly, SLD 30 automatically turns off the monitoring mode upon the return of a registered person and/or registered vehicle.
Knowledge of the locations of the registered vehicles and authorized residents of the dwelling is also useful for responsive actions during the alert/response mode. For example, when an alarm is triggered then the SLD can select the closest vehicle for sending a notification to a user.
A transaction 82 is comprised of SLD 50 requesting that vehicle 30 activate a cellular phone-based emergency response system. Many vehicles are equipped with systems which automatically dial an emergency responder in the event of a vehicle crash. By triggering this feature in response to emergencies detected within the dwelling, valuable time can be saved in the arrival of emergency services.
A transaction 83 is comprised of a request from SLD 50 to vehicle 30 to initiate data recording for evidentiary purposes and event reconstruction. Data can include recorded video streams from vehicle-mounted cameras as well as audio recordings or the recording of vehicle environmental data.
In a transaction 84, SLD 50 may request various kinds of data from vehicle 30. During the monitoring mode, SLD 50 may request environmental data (e.g., captured video, audio, temperature, humidity, or other vehicle sensor data) useful in detecting and classifying monitored events. During the alerting/response mode, SLD 50 may request confirmation of the triggering of responses, for example. In a transaction 85, vehicle 30 provides replies to SLD 50 containing the requested data.
In a transaction 86, SLD 50 sends an alerting message to an occupant of vehicle 30 by way of a displayed text or synthesized speech. In addition, SLD 50 may live-stream audio and/or video signals to vehicle 30 to permit the occupant to more closely monitor activity in the dwelling. In a transaction 87, a responsive action may further include opening a two-way communication channel so that the vehicle occupant can communicate with a person in the dwelling.
In a transaction 88, SLD 50 may request vehicle configuration data from vehicle 30. In particular, such a request may occur during set-up mode so that a user can determine what response actions may be available. Thus, with little or no added expense, the functionality of an SLD-based monitoring/alerting system can be significantly enriched using capabilities of a user's transport vehicle which may or may not be located near the dwelling.
