The present disclosure is directed to technologies associated with autonomous vehicle operation. In particular, the present disclosure is directed to systems and methods for modifying operation of autonomous vehicles in certain situations.
Technologies associated with operation of autonomous vehicles are improving and becoming more ubiquitous. As a result, use of autonomous vehicles on roadways is expected to increase, with autonomous vehicles expected to at least partially replace conventional (i.e., non-autonomous) vehicles. Similar to conventional vehicles, autonomous vehicles may be of different types and for different uses. For example, some autonomous vehicles may serve to transport individuals to a destination, while other autonomous vehicles may be designated for emergency use (e.g., a fire engine or ambulance).
In the event of an emergency situation, such as a dispatch of a fire engine, a hurricane, or a tornado, conventional vehicles may be operated differently than they are in normal situations. For example, conventional vehicles may pull over to the side of the road to allow a fire engine unobstructed access to the road. As another example, a police car may operate at an increased speed in order to more quickly reach a destination. However, there is no way to inform autonomous vehicles, whether emergency or non-emergency, of emergency situations, and thus autonomous vehicles do not operate at optimal efficiency in emergency situations.
Accordingly, there is an opportunity for techniques to detect emergency situations and accordingly facilitate effective operation of autonomous vehicles.
In an embodiment, a computer-implemented method of facilitating operation of an autonomous vehicle is provided. The method may include: detecting an emergency event having an emergency location; and in response to detecting the emergency event: obtaining (i) a current location of the autonomous vehicle and (ii) a current operation of the autonomous vehicle, determining a vehicle operation regulation associated with the current location of the autonomous vehicle, determining, based at least in part on the current operation of the autonomous vehicle, a vehicle operation modification representing a violation of the vehicle operation regulation, generating, by a computer processor based on the vehicle operation modification, a set of vehicle control instructions for the autonomous vehicle, and providing the set of vehicle control instructions to the autonomous vehicle, wherein the autonomous vehicle executes the set of vehicle control instructions to cause the autonomous vehicle to operate according to the vehicle operation modification.
In another embodiment, a system for facilitating operation of an autonomous vehicle is provided. The system may include a communication module configured to communicate with the autonomous vehicle via at least one network connection; a memory storing a set of computer-executable instructions; and a processor interfacing with the communication module and the memory. The processor may be configured to execute the computer-executable instructions to cause the processor to: detect an emergency event having an emergency location, and in response to detecting the emergency event: obtain (i) a current location of the autonomous vehicle and (ii) a current operation of the autonomous vehicle, determine a vehicle operation regulation associated with the current location of the autonomous vehicle, determine, based at least in part on the current operation of the autonomous vehicle, a vehicle operation modification representing a violation of the vehicle operation regulation, generate, based on the vehicle operation modification, a set of vehicle control instructions for the autonomous vehicle, and provide the set of vehicle control instructions to the autonomous vehicle via the communication module, wherein the autonomous vehicle executes the set of vehicle control instructions to cause the autonomous vehicle to operate according to the vehicle operation modification.
In another embodiment, a computer-implemented method in an autonomous vehicle of facilitating operation of the autonomous vehicle is provided. The method may include: detecting an emergency event having an emergency location; and in response to detecting the emergency event: obtaining (i) a current location of the autonomous vehicle and (ii) a current operation of the autonomous vehicle, determining a vehicle operation regulation associated with the current location of the autonomous vehicle, determining, based at least in part on the current operation of the autonomous vehicle, a vehicle operation modification representing a violation of the vehicle operation regulation, generating, by a computer processor based on the vehicle operation modification, a set of vehicle control instructions for the autonomous vehicle, and executing the set of vehicle control instructions to cause the autonomous vehicle to operate according to the vehicle operation modification.
The present embodiments may relate to, inter alia, situational modification of autonomous vehicle operation. According to certain aspects, systems and methods are configured to detect an emergency situation and assess an operation(s) of an autonomous vehicle(s) that may be associated with the emergency situation. The systems and methods may determine how operation of the autonomous vehicle(s) should be modified, generate control instructions for the autonomous vehicle(s), and cause the autonomous vehicle(s) to implement the control instructions to cause the autonomous vehicle(s) to accordingly modify operation.
The systems and methods therefore offer numerous benefits. In particular, the systems and methods promptly detect emergency situations and notify autonomous vehicles of the emergency situations. The emergency situations are thus able to be more effectively addressed and handled, such as by enabling emergency vehicles efficient and effective access to roadways and clearance to a destination. As a result, vehicular safety is improved and individuals who are affected by the emergency situations may experience more effective handling of and service during the emergency situations. It should be appreciated that additional benefits are envisioned.
The systems and methods discussed herein address a challenge that is particular to autonomous vehicular operation. In particular, the challenge relates to a difficulty in effectively and efficiently controlling operation of autonomous vehicles in emergency situations. Conventionally, autonomous vehicles operate according to a set of established rules and inputs associated with their current surroundings, without taking into account emergency situations where operation modification is beneficial.
The systems and methods offer improved capabilities to solve these problems by detecting the occurrence of an emergency event, assessing a configuration or operation of an autonomous vehicle that may be associated with the emergency event, and causing the autonomous vehicle to modify operation so that the emergency event may be effectively and efficiently addressed. Further, because the systems and methods employ the capture, analysis, and transmission of data between and among multiple devices, the systems and methods are necessarily rooted in computer technology in order to overcome the noted shortcomings that specifically arise in the realm of autonomous vehicle operation.

Thus, the computer 106 may be particularly configured with particular elements to thereby be able to perform functions relating to autonomous vehicle automatic operations. Further, the computer 106 may be installed by the manufacturer of the vehicle 108, or as an aftermarket modification or addition to the vehicle 108. In
The system 100 may further include an electronic device 111 that may be associated with the vehicle 108, where the electronic device 111 may be any type of electronic device such as a mobile device (e.g., a smartphone), notebook computer, tablet, phablet, GPS (Global Positioning System) or GPS-enabled device, smart watch, smart glasses, smart bracelet, wearable electronic, PDA (personal digital assistants), pager, computing device configured for wireless communication, and/or the like.

Generally, the individual may at least partially operate the vehicle 108 (and may thus be an operator of the vehicle), or may be a passenger of the vehicle 108 (e.g., if the vehicle 108 is operating autonomously). According to embodiments, the individual may carry or otherwise have possession of the electronic device 111 during operation of the vehicle 108, regardless of whether the individual is the operator or passenger of the vehicle 108.
In some embodiments, the computer 106 may operate in conjunction with the electronic device 111 to perform any or all of the functions described herein as being performed by the vehicle 108. In other embodiments, the computer 106 may perform all of the on-board vehicle functions described herein, in which case the electronic device 111 may not be present or may not be connected to the computer 106. In still other embodiments, the electronic device 111 may perform all of the onboard autonomous vehicle functions described herein. Still further, in some embodiments, the computer 106 and/or the electronic device 111 may perform any or all of the functions described herein in conjunction with one or more of the back-end components 104. For example, in some embodiments or under certain conditions, the electronic device 111 and/or the computer 106 may function as thin-client devices that outsource some or most of the processing to one or more of the back-end components 104.
The computer 106 and/or the electronic device 111 may communicatively interface with one or more on-board sensors 118 that are disposed on or within the vehicle 108 and that may be utilized to monitor the vehicle 108 and the environment in which the vehicle 108 is operating. In particular, the one or more on-board sensors 118 may sense conditions associated with the vehicle 108 and/or associated with the environment in which the vehicle 108 is operating, and may generate sensor data indicative of the sensed conditions. For example, the sensor data may include a location and/or operation data indicative of operation of the vehicle 108. In some configurations, at least some of the on-board sensors 118 may be fixedly disposed at various locations on the vehicle 108. Additionally or alternatively, at least some of the on-board sensors 118 may be incorporated within or connected to the computer 106. Still additionally or alternatively, in some configurations, at least some of the on-board sensors 118 may be included on or within the electronic device 111.
The on-board sensors 118 may communicate respective sensor data to the computer 106 and/or to the electronic device 111, and the sensor data may be processed using the computer 106 and/or the electronic device 111 to determine when the vehicle 108 is in operation as well as determine information regarding operation of the vehicle 108. In some situations, the on-board sensors 118 may communicate respective sensor data indicative of the environment in which the vehicle 108 is operating.
According to embodiments, the sensors 118 may include one or more of a GPS unit, a radar unit, a LIDAR unit, an ultrasonic sensor, an infrared sensor, some other type of electromagnetic energy sensor, an inductance sensor, a camera, an accelerometer, an odometer, a system clock, a gyroscope, a compass, a geo-location or geo-positioning unit, a location tracking sensor, a proximity sensor, a tachometer, a speedometer, and/or the like. Some of the on-board sensors 118 (e.g., GPS, accelerometer, or tachometer units) may provide sensor data indicative of, for example, the vehicle's 108 location, speed, position acceleration, direction, responsiveness to controls, movement, etc.
Other sensors 118 may be directed to the interior or passenger compartment of the vehicle 108, such as cameras, microphones, pressure sensors, weight sensors, thermometers, or similar sensors to monitor any passengers, operations of instruments included in the vehicle 108, operational behaviors of the vehicle 108, and/or conditions within the vehicle 108. For example, on-board sensors 118 directed to the interior of the vehicle 108 may provide sensor data indicative of, for example, in-cabin temperatures, in-cabin noise levels, data from seat sensors (e.g., indicative of whether or not an individual is using a seat, and thus the number of passengers being transported by the vehicle 108), data from seat belt sensors, data regarding the operations of user controlled devices such as windshield wipers, defrosters, traction control, mirror adjustment, interactions with on-board user interfaces, etc.
Some of the sensors 118 disposed at the vehicle 108 (e.g., radar, LIDAR, camera, or other types of units that operate by using electromagnetic energy) may actively or passively scan the environment external to the vehicle 108 for obstacles (e.g., emergency vehicles, other vehicles, buildings, pedestrians, trees, gates, barriers, animals, etc.) and their movement, weather conditions (e.g., precipitation, wind, visibility, or temperature), roadways, road conditions (e.g., lane markings, potholes, road material, traction, or slope), road topography, traffic conditions (e.g., traffic density, traffic congestion, etc.), signs or signals (e.g., traffic signals, speed limits, other jurisdictional signage, construction signs, building signs or numbers, or control gates), and/or other information indicative of the environment of the vehicle 108. Information or data that is generated or received by the on-board sensors 118 may be communicated to the computer 106 and/or to the electronic device 111.
In some embodiments of the system 100, the front-end components 102 may communicate collected sensor data to the back-end components 104 (e.g., via a network(s) 120). In particular, at least one of the computer 106 and the electronic device 111 may communicate with the back-end components 104 via the network(s) 120 to enable the back-end components 104 to record collected sensor data and information regarding autonomous vehicle usage.
The network(s) 120 may include a proprietary network, a secure public internet, a virtual private network, and/or some other type of network, such as dedicated access lines, plain ordinary telephone lines, satellite links, cellular data networks, combinations of these and/or other types of networks. The network(s) 120 may utilize one or more radio frequency communication links to communicatively connect to the vehicle 108, e.g., utilize wireless communication link(s) to communicatively connect with the electronic device 111 and the computer 106. Where the network(s) 120 comprises the Internet or other data packet network, data communications may take place over the network(s) 120 via an Internet or other suitable data packet communication protocol. In some arrangements, the network(s) 120 additionally or alternatively includes one or more wired communication links or networks.
The back-end components 104 include one or more servers or computing devices, which may be implemented as a server bank or cloud computing system 110, and is interchangeably referred to herein as a “remote computing system 110.” The remote computing system 110 may include one or more computer processors adapted and configured to execute various software applications and components of the system 100, in addition to other software applications.
The remote computing system 110 may further include or be communicatively connected to one or more data storage devices or entities 132, which may be adapted to store data related to the operation of the vehicle 108, the environment and context in which the vehicle 108 is operating, and/or other information. For example, the one or more data storage devices 132 may be implemented as a data bank or a cloud data storage system, at least a portion of which may be locally accessed by the remote computing system 110 using a local access mechanism such as a function call or database access mechanism, and/or at least a portion of which may be remotely accessed by the remote computing system 110 using a remote access mechanism such as a communication protocol. The remote computing system 110 may access data stored in the one or more data storage devices 132 when executing various functions and tasks associated with the present disclosure.
The back-end components 104 may further include a set of third-party sources 112, which may be any system, entity, repository, or the like, capable of obtaining and storing data that may be indicative of situations and circumstances associated with vehicle operation. Although
To communicate with the remote computing system 110 and other portions of the back-end components 104, the front-end components 102 may include a communication component(s) 135, 136 that are configured to transmit information to and receive information from the back-end components 104 and, in some embodiments, transmit information to and receive information from other external sources, such as emergency vehicles, other vehicles and/or infrastructure or environmental components disposed within the environment of the vehicle 108. The communication components 135, 136 may include one or more wireless transmitters or transceivers operating at any desired or suitable frequency or frequencies.
Different wireless transmitters or transceivers may operate at different frequencies and/or by using different protocols, if desired. In an example, the electronic device 111 may include a respective communication component 136 for sending or receiving information to and from the remote computing system 110 via the network(s) 120, such as over one or more radio frequency links or wireless communication channels which support a first communication protocol (e.g., GSM, CDMA, LTE, one or more IEEE 802.11 Standards such as Wi-Fi, WiMAX, BLUETOOTH, etc.). Additionally or alternatively, the computer 106 may operate in conjunction with an on-board transceiver or transmitter 135 that is disposed at the vehicle 108 (which may, for example, be fixedly attached to the vehicle 108) for sending or receiving information to and from the remote computing system 110 via the network(s) 120, such as over one or more radio frequency links or wireless communication channels which support the first communication protocol and/or a second communication protocol.
In some embodiments, the computer 106 may operate in conjunction with the electronic device 111 to utilize the communication component 136 of the electronic device 111 to deliver information to the back-end components 104. In some embodiments, the computer 106 may operate in conjunction with the electronic device 111 to utilize the communication component 135 of the vehicle 108 to deliver information to the back-end components 104. In some embodiments, the communication components 135, 136 and their respective links may be utilized by the computer 106 and/or the electronic device 111 to communicate with the back-end components 104.
Accordingly, either one or both of the electronic device 111 or the computer 106 may communicate with the network(s) 120 over the link(s). Additionally, in some configurations, the electronic device 111 and the computer 106 may communicate with one another directly over a wireless or wired link.
In some embodiments of the system 100, the computer 106 and/or the electronic device 111 of the vehicle 108 may communicate with respective on-board computers and/or electronic devices disposed at the additional vehicle(s) 109 (e.g., emergency vehicles, other autonomous vehicles, or other vehicles), either directly or via the network(s) 120. For example, the computer 106 and/or the electronic device 111 disposed at the vehicle 108 may communicate with respective on-board computers and/or mobile devices of the additional vehicle(s) 109 via the network(s) 120 and the communication component(s) 135, 136 by using one or more suitable wireless communication protocols (e.g., GSM, CDMA, LTE, one or more IEEE 802.11 Standards such as Wi-Fi, WiMAX, BLUETOOTH, etc.). In some configurations, the computer 106 may directly communicate with the additional vehicle(s) 109 in a peer-to-peer (P2P) manner, which may utilize, for example, a Wi-Fi direct protocol, a BLUETOOTH or other short range communication protocol, an ad-hoc cellular communication protocol, or any other suitable wireless communication protocol.
In some embodiments, the system 100 may include one or more environmental communication components or devices, examples of which are depicted in
At least some of the off-board sensors 148 may be disposed on or at the one or more infrastructure components 145 or other types of components that are fixedly disposed within the environment in which the vehicle 108 is traveling. Infrastructure components 145 may include roadways, bridges, traffic signals, gates, switches, crossings, parking lots or garages, toll booths, docks, hangars, or other similar physical portions of a transportation system's infrastructure, for example. Other types of infrastructure components 145 at which off-board sensors 148 may be disposed may include a traffic light, a street sign, a railroad crossing signal, a construction notification sign, a roadside display configured to display messages, a billboard display, a parking garage monitoring device, etc. Off-board sensors 148 that are disposed on or near infrastructure components 145 may generate data relating to the presence and location of obstacles or of the infrastructure component 145 itself, weather conditions, traffic conditions, operating status of the infrastructure component 145, and/or behaviors of various vehicles 108, 109, pedestrians, and/or other moving objects within the vicinity of the infrastructure component 145, for example.
Additionally or alternatively, at least some of the off-board sensors 148 that are communicatively connected to the one or more infrastructure devices 145 may be disposed on or at one or more other vehicle(s) 109 operating in the vicinity of the vehicle 108. As such, a particular sensor that is disposed on-board the additional vehicle 109 may be viewed as an off-board sensor 148 with respect to the vehicle 108.
The one or more environmental communication devices 144, 146 may be communicatively connected (either directly or indirectly) to the one or more off-board sensors 148, and thereby may receive information relating to the condition and/or location of the infrastructure components 145, of the environment surrounding the infrastructure components 145, and/or of the other vehicle(s) 109 or objects within the environment of the vehicle 108. In some embodiments, the one or more environmental communication devices 144, 146 may receive information from the vehicle 108, while, in other embodiments, the environmental communication device(s) 144, 146 may transmit information to the vehicle 108.
As previously discussed, at least some of the environmental communication devices 144, 146 may be locally disposed in the environment in which the vehicle 108 is operating. In some embodiments, at least some of the environmental communication devices 144, 146 may be remotely disposed, e.g., at the back-end 104 of the system 100. In some embodiments, at least a portion of the environmental communication devices 144, 146 may be included in (e.g., integral with) one or more off-board sensors 148. In some configurations, at least some of the environmental communication devices 144, 146 may be included or integrated into the one or more on-board communication components 135, 136, the computer 106, the electronic device 111, and/or the additional vehicle(s) 109 or components thereof.
In addition to receiving information from the on-board sensors 118 and off-board sensors 148 associated with the vehicle 108, the computer 106 may directly or indirectly control the operation of the vehicle 108 according to various fully- or semi-autonomous operation features. The autonomous operation features may include software applications or modules implemented by the computer 106 to generate and implement control commands to control the steering, braking, or motive power of the vehicle 108. To facilitate such control, the computer 106 may be communicatively connected to control components of the vehicle 108 by various electrical or electromechanical control components (not shown).
When a control command is generated by the computer 106, it may thus be communicated to the control components of the vehicle 108 to effect a control action. In embodiments involving fully autonomous vehicles, the vehicle 108 may be operable only through such control components (not shown). In other embodiments, the control components may be disposed within or supplement other vehicle operator control components (not shown), such as steering wheels, accelerator or brake pedals, or ignition switches.
Further, the computer 106 may control one or more operations of the vehicle 108 when the vehicle is operating non-autonomously. For example, the computer 106 may automatically detect respective triggering conditions and automatically activate corresponding features such as traction control, windshield wipers, headlights, braking, etc.
In embodiments, the remote computing system 110 may alternatively or additionally control the operation of the vehicle 108 according to various fully- or semi-autonomous operation features. In particular, the remote computing system 110 may include software applications or modules to generate and implement control commands to control the steering, braking, or motive power of the vehicle 108. In operation, the remote computing system 110 may generate control command(s) and communicate the control command(s) to the computer 106 via the network(s) 120 and the communication component 135, which may communicate the command(s) to the control components of the vehicle 108 to effect a control action.
In one implementation, the computing system 210 may be remote (i.e., back-end) from the autonomous vehicle 208, in which case the computing system 210 may communicate with the autonomous vehicle 208 via one or more networks. In another implementation, the computing system 210 may be included as part of (i.e., on board) the autonomous vehicle 208, in which case the computing system 210 may include a computer and a set of components configured to control operation of the autonomous vehicle 208.
The signal diagram 200 may begin when one of the set of third party sources 212 optionally transmits (220) a notification of an emergency event. According to embodiments, the emergency event may be indicative of an event or situation for which emergency services (e.g., fire prevention or containment, medical services, police attention) may be needed. The emergency event may affect or potentially affect one or more individuals, one or more vehicles, one or more properties, one or more physical areas, and/or the like. The third-party source 212 may be a dispatch center, an emergency services provider (e.g., a police station), or a component or entity that determines, based on collected data or information, that an emergency event has occurred or may occur. For example, the third-party source 212 may be a weather service that determines the existence of a hurricane in a particular area. According to embodiments, the emergency event may have an associated location. For example, if the emergency event is a house on fire, then the location may be the address of the house.
Alternatively or additionally, the computing system 210 itself may detect (222) the emergency event. In an embodiment, the computing system 210 may collect and analyze data to determine that an emergency event has occurred. For example, the computing system 210 may collect sensor data from an infrastructure component that indicates a stalled vehicle in the roadway.
In response to detecting the emergency event (or receiving the indication of the emergency event from the third-party source 212), the computing system 210 may retrieve (224) location and operation data from the autonomous vehicle 208 (or from a component thereof). According to embodiments, the location may be in the form of GPS coordinates, and may indicate a roadway on which the autonomous vehicle 208 is traveling or has traveled. Further, the operation data may indicate one or more of: a speed, a direction of travel, additional telematics data (e.g., turning data, acceleration data, braking data, etc.), an origin location, a destination location, and/or the like.
The computing system 210 may further retrieve (226) an operation regulation(s) from the third party source(s) 212. In retrieving the operation regulation, the computing system 210 may provide, to the third party source(s) 212, the location and/or any of the operation data retrieved from the autonomous vehicle 208. The third-party source(s) 212 may be a component or entity that creates, stores, and/or maintains operation regulations and statuses of and/or updates thereto. In an embodiment, the computing system 210 may locally identify or determine the operation regulation without interfacing with the third-party source(s) 212.
In embodiments, the operation regulation may be a rule or regulation associated with vehicular travel that may be applicable to the autonomous vehicle 208. For example, the operation regulation may indicate a speed limit, temporary or permanent road or traffic markings or signs (e.g., construction zones, yield signs, stop signs, traffic lights and statuses thereof, etc.), road or surface uses (e.g., parking lots, bus-only lanes, bike lanes, no standing or stopping lanes, etc.), and/or similar rules or regulations.
In embodiments, the operation regulation(s) may be specific to emergency vehicle operation and/or to non-emergency vehicle operation. For example, a particular roadway may have a first speed limit for emergency vehicle operation and a second (e.g., lower) speed limit for non-emergency vehicle operation. For further example, an emergency vehicle operation regulation may allow U-turns on a particular roadway and a non-emergency vehicle operation regulation may disallow U-turns on the particular roadway. It should be appreciated that additional differences between emergency and non-emergency vehicle regulations are envisioned.
Generally, the operation regulation may be associated with the location and/or the operation data of the autonomous vehicle 208. For example, the operation regulation(s) may specify a speed limit of a particular roadway on which the autonomous vehicle 208 is traveling as well as a status (e.g., red, yellow, or green) of a traffic signal that the autonomous vehicle 208 is approaching.
The computing system 210 may determine (228) an operation modification. Generally, the operation modification may represent how operation of the autonomous vehicle 208 should be modified to address handling of the emergency event, such as to enable the emergency event to be addressed or handled more efficiently or effectively. The computing system 210 may determine the operation modification based on at least one of: whether the autonomous vehicle 208 is an emergency or non-emergency vehicle, the operation regulation (and whether the operation regulation is specific to emergency vehicle operation or to non-emergency vehicle operation), the location and/or operation data of the autonomous vehicle 208, the location of the emergency event, and/or other parameters. In determining the operation modification, the computing system 210 may determine how the operation modification may enable the emergency event to be more effectively and efficiently addressed.
For example, if the autonomous vehicle 208 is an emergency vehicle, the operation modification may be to increase the velocity or speed of travel of the autonomous vehicle 208 so that the autonomous vehicle 208 may reach its destination (e.g., the location of the emergency event) in a reduced amount of time. For further example, if the autonomous vehicle 208 is a non-emergency vehicle, the operation modification may be to reposition the autonomous vehicle 208 to the shoulder of a roadway to enable an emergency vehicle (autonomous or non-autonomous) to effectively pass the autonomous vehicle 208. As an additional example, the operation modification may be to cause the autonomous vehicle 208 to violate a current signal of a traffic light. In this example, the operation modification may be to proceed through a red/stop signal or to stop at a green/proceed signal. It should be appreciated that additional or alternative situations are envisioned.
Generally, the operation modification may represent a violation of the operation regulation retrieved or identified in (226). In normal (i.e., non-emergency) operation, the autonomous vehicle 208 may operate in accordance with any applicable operation regulation(s). However, in an emergency situation, the operation of the autonomous vehicle 208 may be modified so that the emergency event is more effectively handled or addressed. For example, if the operation regulation is a speed limit of 25 mph for a particular roadway, the operation modification may be a speed increase to 30 mph for the autonomous vehicle 208. For further example, if the operation regulation specifies a one-way street, the operation modification may be to direct the autonomous vehicle 208 to travel the wrong way on the one-way street.
In embodiments, the operation modification may represent one or more parameters that replaces one or more corresponding operation regulations, whether an emergency vehicle operation regulation(s) or a non-emergency vehicle operation regulation(s). For example, the operation modification may be: (1) set max speed to a maximum speed of the vehicle; (2) set traffic light response to proceed when possible; (3) set lane marking response to “ignore”; and/or (4) set regulatory road sign response to ignore.
The computing system 210 may generate (230) a set of instructions based on the operation modification generated in (228). In embodiments, the set of instructions may be configured to be executed by a computer associated with the autonomous vehicle 208 (which, in some cases, may be the computing system 210), to cause the autonomous vehicle 208 to undertake or complete the operation modification.
In situations in which the computing system 210 is remote from the autonomous vehicle 208, the computing system 210 may transmit (232) the set of instructions to the autonomous vehicle 208 via a network connection. After receipt or generation of the set of instructions, a computing device of the autonomous vehicle 208 may execute (234) the set of instructions to effectively cause the autonomous vehicle 208 to operate according to the operation modification determined in (228). In an embodiment, if an individual is present in the autonomous vehicle 208, the autonomous vehicle 208 may present (e.g., via a user interface) an indication of the operation modification, and many optionally enable the individual to approve initiation of the operation modification. Further, in an embodiment, the autonomous vehicle 208 may automatically execute the set of instructions in response to receiving the set of instructions or generating the set of instructions.
After executing the set of instructions, the autonomous vehicle 208 may generate and transmit (236) an acknowledgement that the set of instructions were executed and that the operation modification was implemented. The computing device 210 may record (238) the acknowledgement in memory or similar component. Accordingly, the computing device 210 may subsequently access the acknowledgment and any data relating thereto, such as in determining a subsequent operation modification for the autonomous vehicle 208 and/or any additional autonomous vehicle.
The method 300 may begin when the computing device determines (block 305) whether an emergency event is detected, where the emergency event may have an associated emergency location. In embodiments, the computing device may locally detect the emergency event or may be notified of the emergency event from a third-party source or component. If an emergency event is not detected (“NO”), processing may repeat or proceed to other functionality.
If an emergency event is detected (“YES”), the computing device may obtain (block 310) (i) a current location of the autonomous vehicle and (ii) a current operation of the autonomous vehicle. In embodiments, the current operation of the autonomous vehicle may include various telematics data or other information associated with current or recent operation of the autonomous vehicle.
The computing device may determine (block 315) a vehicle operation regulation associated with the location of the autonomous vehicle. In embodiments, the computing device may locally determine the vehicle operation regulation or may interface with a third-party source or component to retrieve the vehicle operation regulation.
The computing device may determine (block 320), based at least in part on the current operation of the autonomous vehicle, a vehicle operation modification representing a violation of the vehicle operation regulation. In embodiments, the computing device may determine the vehicle operation modification further based on the emergency location of the emergency event.
In the event that the autonomous vehicle is an emergency vehicle, the vehicle operation regulation may be a speed limit associated with the location of the emergency autonomous vehicle, and the vehicle operation modification may correspond to an operation speed of the emergency autonomous vehicle in excess of the speed limit. Alternatively, the vehicle operation regulation may be a traffic light having a current signal associated with the location of the autonomous vehicle, and the vehicle operation modification may correspond to an autonomous vehicle movement of the autonomous vehicle in violation of the current signal of the traffic light. For example, the vehicle operation modification for an emergency autonomous vehicle may be to proceed through a red light, and the vehicle operation modification for a non-emergency autonomous vehicle may be to stop at a green light, thus enabling the emergency autonomous vehicle with better clearance. Alternatively, the vehicle operation regulation may be a direction of travel of a roadway associated with the location of the autonomous vehicle, and the vehicle operation modification may correspond to an intended direction of travel of the autonomous vehicle along the roadway opposite from the direction of travel of the roadway. As an example, the vehicle operation modification may enable a group of autonomous vehicles to travel on all lanes of a highway, such as during an evacuation of a hurricane. It should be appreciated that, in these instances, the autonomous vehicle may be an emergency or non-emergency vehicle.
The computing device may generate (block 325), based on the vehicle operation modification, a set of vehicle control instructions for the autonomous vehicle. As indicated herein, the computing device may be remote from or on board the autonomous vehicle which is resolved in block 330. If the computing device is on board the autonomous vehicle (“ONBOARD”), the computing device may execute (block 335) the set of vehicle control instructions to cause the autonomous vehicle to operate according to the vehicle operation modification. Conversely, if the computing device is remote from the autonomous vehicle (“REMOTE”), the computing device may provide (block 340) the set of vehicle control instructions to the autonomous vehicle such that the autonomous vehicle executes the set of vehicle control instructions to cause the autonomous vehicle to operate according to the vehicle operation modification.

In some embodiments, the computer program product may be part of a cloud network of resources.
Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the invention may be defined by the words of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment, as describing every possible embodiment would be impractical, if not impossible. One could implement numerous alternate embodiments, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.
Throughout this specification, plural instances may implement components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently, and nothing requires that the operations be performed in the order illustrated. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components. These and other variations, modifications, additions, and improvements fall within the scope of the subject matter herein.
Additionally, certain embodiments are described herein as including logic or a number of routines, subroutines, applications, or instructions. These may constitute either software (e.g., code embodied on a non-transitory, machine-readable medium) or hardware. In hardware, the routines, etc., are tangible units capable of performing certain operations and may be configured or arranged in a certain manner. In example embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein.
In various embodiments, a hardware module may be implemented mechanically or electronically. For example, a hardware module may comprise dedicated circuitry or logic that may be permanently configured (e.g., as a special-purpose processor, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) to perform certain operations. A hardware module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that may be temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.
Accordingly, the term “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where the hardware modules comprise a general-purpose processor configured using software, the general-purpose processor may be configured as respective different hardware modules at different times. Software may accordingly configure a processor, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.
Hardware modules may provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple of such hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it may be communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and may operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processor-implemented modules.
Similarly, the methods or routines described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented hardware modules. The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor or processors may be located in a single location (e.g., within a home environment, an office environment, or as a server farm), while in other embodiments the processors may be distributed across a number of locations.
The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the one or more processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the one or more processors or processor-implemented modules may be distributed across a number of geographic locations.
Unless specifically stated otherwise, discussions herein using words such as “processing,” “computing,” “calculating,” “determining,” “presenting,” “displaying,” or the like may refer to actions or processes of a machine (e.g., a computer) that manipulates or transforms data represented as physical (e.g., electronic, magnetic, or optical) quantities within one or more memories (e.g., volatile memory, non-volatile memory, or a combination thereof), registers, or other machine components that receive, store, transmit, or display information.
As used herein any reference to “one embodiment” or “an embodiment” means that a particular element, feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.
As used herein, the terms “comprises,” “comprising,” “may include,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
In addition, use of the “a” or “an” are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the description. This description, and the claims that follow, should be read to include one or at least one and the singular also may include the plural unless it is obvious that it is meant otherwise.
This detailed description is to be construed as examples and does not describe every possible embodiment, as describing every possible embodiment would be impractical, if not impossible. One could implement numerous alternate embodiments, using either current technology or technology developed after the filing date of this application.
The patent claims at the end of this patent application are not intended to be construed under 35 U.S.C. § 112(f) unless traditional means-plus-function language is expressly recited, such as “means for” or “step for” language being explicitly recited in the claim(s). The systems and methods described herein are directed to an improvement to computer functionality, and improve the functioning of conventional computers.
This application is a continuation of U.S. patent application Ser. No. 16/803,661, filed Feb. 27, 2020, which is a continuation of U.S. patent application Ser. No. 15/811,207 (now U.S. Pat. No. 10,593,202), filed Nov. 13, 2017. These disclosures are hereby incorporated by reference in their entireties.
