The subject matter described herein relates, in general, to systems and methods for adjusting one or more properties of an existing vehicular micro cloud.
Some connected vehicles can form groups of interconnected vehicles so as to share resources as the interconnected vehicles navigate through an environment. Vehicle members of the group, which is known as a “vehicular micro cloud” can be located within a similar geographic location.
Properties of a vehicular micro cloud are set when the vehicular micro cloud is formed, and can remain static. As such, a change in the environment can leave vehicle members unable to share resources to navigate the change in the environment as the vehicular micro cloud with its static properties becomes obsolete
In one embodiment, a method for dynamically updating an existing vehicular micro cloud is disclosed. The method includes determining one or more parameters of an environment around a plurality of vehicles, and identifying an impact of the one or more parameters of the environment on one or more of the plurality of vehicles associated with the existing vehicular micro cloud. The method also includes identifying one or more properties of the existing vehicular micro cloud. The method includes determining which adjustment to the one or more properties of the existing vehicular micro cloud can address the impact, and updating the one or more properties based on the determination.
In another embodiment, a system for dynamically updating an existing vehicular micro cloud is disclosed. The system includes one or more processors, and a memory in communication with the one or more processors. The memory stores an environment parameter determination module including instructions that when executed by the one or more processors cause the one or more processors to determine one or more parameters of an environment around a plurality of vehicles. The memory stores an impact detection module including instructions that when executed by the one or more processors cause the one or more processors to identify an impact of the one or more parameters of the environment on one or more of the plurality of vehicles associated with the existing vehicular micro cloud. The memory stores a vehicular micro cloud update module including instructions that when executed by the one or more processors cause the one or more processors to identify one or more properties of the existing vehicular micro cloud, determine which adjustment to the one or more properties of the existing vehicular micro cloud can address the impact, and update the one or more properties based on the determination.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various systems, methods, and other embodiments of the disclosure. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one embodiment of the boundaries. In some embodiments, one element may be designed as multiple elements or multiple elements may be designed as one element. In some embodiments, an element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.
Systems, methods, and other embodiments associated with dynamically updating an existing vehicular micro cloud are disclosed. A plurality of connected vehicles can form a vehicular micro cloud so that the connected vehicles (being vehicular micro cloud members) can share information and resources to assist the connected vehicles collaborating in an environment. Properties of the vehicular micro cloud can be selected based on the characteristics or parameters of the environment. As such, the properties of the vehicular micro cloud are set when the vehicular micro cloud is formed.
The parameters can be influencing parameters for detecting and/or measuring an impact on the connected vehicles. The influencing parameters can be intrinsic and related to the vehicular micro cloud. Additionally and/or alternatively, the influencing parameters can be extrinsic and related to the environment. The parameters such as a priority, a task, and/or a purpose of the vehicular micro cloud can change over time, and with that, the type of resources the connected vehicles may use to collaborate in the environment can change. As an example, the connected vehicles can do one or more of assisting each other, sharing computational resources, communicating with each other, and any other suitable form of collaboration. A vehicular micro cloud set up for connected vehicles in one environment may be unsuitable for the connected vehicles in another environment.
Accordingly, in one embodiment, the disclosed approach is a system that dynamically updates an existing vehicular micro cloud. In other words, the system can dynamically update the properties of the existing vehicular micro cloud.
The system can determine the parameters of the environment by receiving information about the environment from sensors such as vehicle sensors or roadside sensors. The information can include information about traffic flow or traffic density, vehicle collisions, parked vehicles, road conditions, weather conditions, and/or visibility issues. The information can be static and/or dynamic. Further, the information can be based on actual and/or predicted values.
The system can determine what the properties of a vehicular micro cloud that would be suitable in assisting vehicular micro cloud members as the vehicular micro cloud members navigate the environment. The system can determine whether the properties of the existing vehicular micro cloud are suitable for assisting the vehicular micro cloud members navigating through the environment.
In the case that the system determines that the properties of the existing vehicular micro cloud are unsuitable, the system can update the properties of the existing vehicular micro cloud. As an example, the system can instruct a vehicular micro cloud member with access to the property settings of the vehicular micro cloud to change the properties.

In some implementation, the vehicle can be a watercraft, an aircraft, or any other form of motorized transport. The connected vehicle 102 can be a vehicle that is communicatively linked to one or more elements of the DVMCA system 100.
The DVMCA system 100 can include the one or more vehicular micro cloud(s) 120. A vehicular micro cloud 120 is a wireless network system in which a plurality of the connected vehicles 102, and optionally, devices such as non-vehicle node, form a group of interconnected member vehicles 102. The interconnected member vehicles 102, also known as vehicular micro cloud members, can communicate and share resources with each other using, as an example, V2V communication. The vehicular micro cloud members 102 can include one or more cloud leaders 104. The cloud leader(s) 104 can be the vehicular micro cloud member 102 that forms, maintains and/or updates the vehicular micro cloud 120. The cloud leader 104 can determine and/or manage how the computing resources of the vehicular micro cloud 120 are utilized by the vehicular micro cloud members 102.
The vehicular micro cloud 120 can have one or more properties disclosed herein. As an example, the properties of the vehicular micro cloud 120 can be stored, maintained, and updated by the cloud leader 104. The one or more properties of the vehicular micro cloud 120 can include a priority. The priority can be a goal for the vehicular micro cloud 120. As an example, the priority of the vehicular micro cloud 120 can be safety, comfort, and time management. In some arrangements, one of safety, comfort, and time management can be of higher importance than the other two. In a case where the priority of the vehicular micro cloud 120 is safety, the vehicular micro cloud 120 can be formed and maintained to advance the safety of passenger(s) and/or pedestrian(s). As an example, the vehicular micro cloud members 102 can exchange information such as weather conditions, road conditions, and traffic conditions, and share resources to determine safe routes. As another example, if the vehicular micro cloud member 102 has information that indicates that a driver can be easily distracted, the vehicular micro cloud member 102 can share resources to identify and travel on routes with less or no distractions. In a case where the priority of the vehicular micro cloud 120 is comfort, the vehicular micro cloud 120 can be formed and maintained to advance the comfort of the passengers. As an example, the vehicular micro cloud members 102 can share resources to identify the routes that provide the smoothest rides. The vehicular micro cloud members 102 can share resources so as to, as an example, drive at a comforting speed and change lanes in a smooth manner. In a case where the priority of the vehicular micro cloud 120 is time management, the vehicular micro cloud 120 can be formed and maintained to manage the travel time of the passenger(s). The vehicular micro cloud members 102 can share resources to determine traffic conditions and the fastest route(s) so as to minimize travel time. In some other arrangements, two of safety, comfort, and time management can be of higher importance than the remaining third. In some other arrangements, safety, comfort, and time management can be of equal importance.
The one or more properties of the vehicular micro cloud 120 can include a mobility type. The mobility type can refer to whether the vehicular micro cloud 120 is movable or immovable. In such a case, the vehicular micro cloud 120 can be a stationary vehicular micro cloud 120 or a mobile vehicular micro cloud 120. A stationary vehicular micro cloud 120 can be tied to a fixed geographic location, e.g., an intersection. In such a case, a connected vehicle can join the stationary vehicular micro cloud 120 when the connected vehicle is within the fixed geographic location of the stationary vehicular micro cloud 120. The connected vehicle can leave the stationary vehicular micro cloud 120 when the connected vehicle exits the fixed geographic location of the stationary vehicular micro cloud 120. A mobile vehicular micro cloud 120 can be tied to vehicular micro cloud members that are travelling in the same direction. The mobile vehicular micro cloud 120 can travel with the vehicular micro cloud members, and as such, the geographic location of the mobile vehicular micro cloud 120 moves with the vehicular micro cloud members. A connected vehicle can join the mobile vehicular micro cloud 120 when the connected vehicle is in an area covered by the mobile vehicular micro cloud 120. The connected vehicle can leave the mobile vehicular micro cloud 120 when the connected vehicle exits the area covered by the mobile vehicular micro cloud 120.
The one or more properties of the vehicular micro cloud 120 can include an origin type. The origin type can refer to the circumstances under which the vehicular micro cloud 120 is formed. As an example, a vehicular micro cloud 120 can be a pre-assigned vehicular micro cloud 120 or an on-demand vehicular micro cloud 120.

In such a case, the vehicular micro cloud 120 can remain small scale as the vehicular micro cloud 120 and can limit communication with other vehicular micro clouds 120. The scale type can be large scale such as a vehicular macro cloud. The vehicular macro cloud can include a plurality of connected vehicles spanning a large geographical region such as a city. The member vehicles of the vehicular macro cloud can communicate across a city, as an example, using any suitable network such as V2V or V2I communication networks. The member vehicles of the vehicular macro cloud can belong to one or more vehicular micro clouds 120. The one or more vehicular micro clouds 120 can communicate with each other to form the vehicular macro cloud. The vehicular micro cloud 120 can include a plurality of connected vehicles within a limited geographical region. The member vehicles of the vehicular micro cloud 120 can communicate and share resources with each other using, as an example, V2V communication. The vehicular micro cloud members 102 can include one or more cloud leader vehicles 104 of the vehicular micro cloud 120.

In one embodiment, the vehicular micro cloud adjustment system 270 can include a memory 310 that stores an environment parameter determination module 320, an impact identification module 330, and a vehicular micro cloud update module 340. The memory 310 is a random-access memory (RAM), read-only memory (ROM), a hard-disk drive, a flash memory, or other suitable memory for storing the modules 320, 330, and 340. The environment parameter determination module 320, the impact identification module 330, and the vehicular micro cloud update module 340 are, for example, computer-readable instructions within the physical memory 310 that when executed by the processor 210 cause the processor 210 to perform the various functions disclosed herein.
In one embodiment, the vehicular micro cloud adjustment system 270 can include a data store 350. The data store 350 is, in one embodiment, an electronic data structure (e.g., a database) stored in the memory 310 or another data store and that is configured with routines that can be executed by the processor 210 for analyzing stored data, providing stored data, organizing stored data, and so on. Thus, in one embodiment, the data store 350 can store data used by the modules 320, 330 and 340 in executing various functions. In one embodiment, the data store 350 can include traffic records data 360, vehicular micro cloud properties data 370, impact and matching properties data 380 and or other information that is used by the modules 320, 330, and 340.
The traffic records data 360 can contain statistical records of past traffic information such as traffic patterns based on geographic location and time of day. The traffic records data 360 can include previously recorded traffic information for the geographic location. The vehicular micro cloud properties data 370 can include information about the properties of the existing vehicular micro cloud 120. The properties are described in detail above. The impact and matching properties data 380 can include a database populated with the various types of impacts matched with the adjustments to the properties of the existing vehicular micro cloud 120 that can address each of the various impacts. In other words, the database can include mapping an impact to vehicular micro cloud properties that can address the impact. As an example, an entry in the database can include the impact being a portion of a road along the route of travel is inaccessible due to flooding, and the adjustments to address the impact can include adjusting priority to safety, mobility type to stationary, dependency type to interdependent, communication category to V2C communication, and/or optimization method to maximize safety while traversing the flooded road. The mapping can be determined using any suitable method such as based on a statistical analysis and/or machine learning algorithms.
In one embodiment, the environment parameter determination module 320 can include instructions that function to control the processor 210 to determine one or more parameters of an environment around a plurality of vehicles. As such, the environment can be around one or more vehicles. As an example, the vehicle(s) can be member vehicle(s) of the vehicular micro cloud 120. Alternatively, the vehicle(s) may not be member vehicle(s) of the vehicular micro cloud 120. In such a case and as an example, the vehicle(s) can be located ahead of the vehicular micro cloud 120 along a travel route. As another example, the vehicle(s) can be located behind the vehicular micro cloud 120 along the route.
The parameter(s) of the environment can be a characteristic of the environment that can affect a vehicle travelling in or towards the environment. As an example, a parameter can be a vehicle accident that has occurred in the environment. As another example, a parameter can be a parked or stalled vehicle in the environment. As another example, a parameter can be traffic congestion in the environment. Similar to the vehicle accident and stalled vehicle, the traffic congestion can cause the vehicle to change its travel route and/or recalculate its travel time. As another example, a parameter can be a road condition in the environment. The road condition can be, as an example, road damage such as a pothole, or road flooding. As another example, a parameter can be a weather condition in the environment. The aforementioned examples of parameters can cause the vehicle to change its travel route and/or recalculate its travel time.
The environment parameter determination module 320 can further include instructions that function to control the processor to monitor the environment. The environment parameter determination module 320 can receive information about the environment from vehicle sensors. Alternatively and/or additionally, the environment parameter determination module 320 can receive information about the environment from external sources. The external sources may include any entities capable of wireless communication such as other vehicles, roadside units, servers, and/or databases.
The information about the environment can include a weather condition, a road condition, location of the road segment(s), and/or timestamp. The weather condition may include, as an example, presence of precipitation such as snow, rain, and/or hail. The weather condition may further include impacts of weather such as fog levels, fallen snow levels (i.e. the amount of snow on the ground), and/or flooding. The weather condition may be updated periodically and/or on-demand. The road condition may include information about the physical condition of the road segment(s). The road condition may include the presence of potholes, road debris, overgrown vegetation, the slope of the road segment(s), the curvature of the road segment(s), and/or the friction level of the road segment(s).
The environment parameter determination module 320 can determine the parameters of the environment based on predicting events that can occur in the environment. As an example, the environment parameter determination module 320 can access a database such as the data store(s) 350 to determine the amount of traffic that can be expected on a certain road at a certain time and day. As an example, the environment parameter determination module 320 can access and process information in the traffic records data 360 to predict parameters of the environment.
The impact identification module 330 can include instructions that function to control the processor 210 to identify an impact of the one or more parameters of the environment on one or more of the plurality of vehicles associated with the existing vehicular micro cloud 120. The vehicles associated with the existing vehicular micro cloud 120 can be member vehicles of the existing vehicular micro cloud 120. Alternatively, the vehicles associated with the existing vehicular micro cloud 120 can be vehicles that are not member vehicles of the existing vehicular micro cloud 120 but are proximate to the geographical location of the existing vehicular micro cloud 120.
The impact identification module 330 can use any suitable algorithm such as a machine learning algorithm or an artificial intelligence process to identify the impact of the one or more parameters of the environment on the vehicles associated with the existing vehicular micro cloud 120. As an example, the impact identification module 330 can determine that the impact of a vehicle accident on a vehicle can be road closure such that the impacted vehicle is unable to traverse along an intended route. As another example, the impact identification module 330 can determine that the impact of a vehicle accident can be traffic congestion such that the impacted vehicle encounters a time delay. As another example, the impact identification module 330 can determine that the impact of a vehicle accident can result in a safety risk as drivers get distracted as they drive by and observe the vehicle accident.
The impact identification module 330 can determine the impact of the parameters of the environment on a vehicle based on the parameters of the environment and other factors such as time of day and vehicle location. As an example, the impact identification module 330 can determine that the impact on a vehicle is a time delay when there is a vehicle accident, and the vehicle is on a high traffic road such as a highway at a peak time such as an evening rush hour. As another example, the impact identification module 330 can determine that the impact on the vehicle can be that the intended route of travel is blocked or unavailable when there is flooding or a fallen tree on a road along the intended route.
The vehicular micro cloud update module 340 can include instructions that function to control the processor 210 to identify one or more properties of the existing vehicular micro cloud 120, determine which adjustment to the one or more properties of the existing vehicular micro cloud 120 can address the impact, and update the one or more properties based on the determination.
The vehicular micro cloud update module 340 can identify the properties of the existing vehicular micro cloud 120 by, as an example, requesting the properties of the existing vehicular micro cloud 120 from the cloud leader. In such a case, the vehicular micro cloud update module 340 can request the information from the cloud leader using a suitable means of communication. As another example, the vehicular micro cloud update module 340 can access the properties of the existing vehicular micro cloud 120 from the data store(s) 350. In such an example and as previously explained, the data store(s) 350 can include vehicular micro cloud properties data 370 that contain the properties of the existing vehicular micro cloud 120. The vehicular micro cloud update module 340 can receive the information which can include the mobility type, the priority, the origin type, the size type, communication category, the dependency type, and/or the collaboration criteria of the vehicular micro cloud 120. As another example, the vehicular micro cloud update module 340 can identify the properties of the existing vehicular micro cloud 120 by monitoring or observing the existing vehicular micro cloud 120.
The vehicular micro cloud update module 340 can determine which adjustment to the one or more properties of the existing vehicular micro cloud 120 can address the impact to the vehicles. The vehicular micro cloud update module 340 can use any suitable algorithm to determine which adjustments to the properties of the existing vehicular micro cloud 120 can address the impact. As an example, the vehicular micro cloud update module 340 can access a database populated with the various types of impacts matched with the adjustments to the properties of the existing vehicular micro cloud 120 that can address each of the various impacts such as the impact and matching properties data 380 in the data store(s).
The vehicular micro cloud update module 340 can include instructions that function to control the processor 210 to update the one or more properties based on the determination. The vehicular micro cloud update module 340 can identify an original reason for the existing vehicular micro cloud 120. The original reason refers to a reason that led to the existing vehicular micro cloud 120 being formed and/or continuing to exist. The original reason can be based on one or more of traffic flow, traffic density, a vehicle accident, a road closure, an unusual event, and a risk. In other words, the existing vehicular micro cloud 120 can be formed or can continue to exist to assist vehicles as the vehicles travel amidst one or more of the traffic flow, the traffic density, the vehicle accident, the road closure, an unusual event, and any other risk. The vehicular micro cloud update module 340 can identify the original reason for the existing vehicular micro cloud 120 by requesting information about the original reason from a cloud member 102 or a cloud leader 104.
The vehicular micro cloud update module 340 can identify a new reason for the existing vehicular micro cloud 120 based on the one or more parameters of the environment. In other words, the vehicular micro cloud update module 340 can identify the new reason for the existing vehicular micro cloud 120 as a reason that a vehicular micro cloud 120 can be formed or can exist such that the vehicular micro cloud 120 can assist vehicles as the vehicles address the impact of the parameters of the environment. The vehicular micro cloud update module 340 can determine the new reason using any suitable algorithm. As an example, the vehicular micro cloud update module 340 can access a database populated with the various parameters matched with the reason for a vehicular micro cloud 120. The vehicular micro cloud update module 340 can determine the new reason for the vehicular micro cloud 120 by identifying the parameters of the environment in the database and retrieving a reason matched to identified parameters.
The vehicular micro cloud update module 340 can determine that the original reason and the new reason are different. In other words, the vehicular micro cloud update module 340 can compare the original reason and the new reason to determine whether the original reason and the new reason are the same or different.
The vehicular micro cloud update module 340 can, in response to determining that the original reason and the new reason are different, determine which adjustment to the one or more properties of the existing vehicular micro cloud 120 can address the impact based on the new reason. The vehicular micro cloud update module 340 can update the properties of the existing vehicular micro cloud 120 based on the determined adjustment(s) in response to the original reason and the new reason for the existing vehicular micro cloud 120 being different.
The vehicular micro cloud update module 340 can update the properties by transmitting the determined properties to the cloud leader 104 using any suitable communication means. As an example, the vehicular micro cloud update module 340 can transmit a message to the cloud leader 104 indicating that the properties of the vehicular micro cloud 120 be updated from stationary to mobile, from independent to interdependent, from time management priority to safety priority, and/or from ad-hoc communication to hybrid communication. As another example, the vehicular micro cloud update module 340 can determine that another vehicle 102 other than the current cloud leader 104 become the cloud leader 104. In such an example, the vehicular micro cloud update module 340 can transmit a message to the other vehicle 102 requesting the other vehicle 102 become the cloud leader 104 and indicating the updated properties of the vehicular micro cloud 120.
The vehicular micro cloud adjustment system 270 may be further implemented as a cloud-based system that functions within a cloud-computing environment 400 as illustrated in relation to
Along with the communications, the connected vehicles 410-430 may provide sensor data 219. As such, the cloud-based aspects of the vehicular micro cloud adjustment system 270 may then process the sensor data 219 separately for the vehicles 410-430 to determine the one or more parameters of the environment. In further aspects, the vehicle-based systems may perform part of the processing while the cloud-computing environment 400 may handle a remaining portion or function to validate results of the vehicle-based systems. It should be appreciated that apportionment of the processing between the vehicle and the cloud may vary according to different implementations. Additional aspects of the cloud computing environment 400 are discussed above in relation to components of the vehicular micro cloud adjustment system 270 and
At step 510, the environment parameter determination module 320 can cause the processor(s) 210 to determine one or more parameters of an environment around a plurality of vehicles. As previously mentioned, the environment parameter determination module 320 can determine the parameters by receiving sensor data from vehicle sensors or by receiving information from external sources such as other vehicles or database servers.
At step 520, the impact identification module 330 can cause the processor(s) 210 to identify an impact of the one or more parameters of the environment on one or more of the plurality of vehicles associated with the existing vehicular micro cloud 120. As an example, the impact identification module 330 can identify the impact based on a statistical analysis and/or machine learning methods. An example of an impact can include a portion of a road along the travel route of the vehicle(s) being inaccessible.
At step 530, the vehicular micro cloud update module 340 can cause the processor(s) 210 to identify one or more properties of the existing vehicular micro cloud 120, as discussed above.

The vehicular micro cloud adjustment system 270, or more specifically, the impact identification module 330 can identify an impact of the parameters of the environment on the vehicle(s) associated with the existing vehicular micro cloud 120. The impact identification module 330 can determine that the impact of the collision can be traffic congestion based on the information that includes a vehicle collision at the intersection, the number of vehicles in the intersection and the number of vehicles approaching the intersection. The impact identification module 330 can further determine that traffic congestion can increase the risk of additional collisions. As previously mentioned, the impact identification module 330 can use any suitable algorithm to determine the impact of the collision on the vehicles in the environment.
The vehicular micro cloud adjustment system 270, or more specifically the vehicular micro cloud update module 340 can identify one or more properties of the existing vehicular micro cloud 120. The vehicular micro cloud update module 340 can identify the properties by requesting the information from, as an example, the cloud leader 604 or the server 130. Alternatively and/or in addition, the vehicular micro cloud update module 340 can observe the environment to determine the properties of the vehicular micro cloud 120. In this example, the vehicular micro cloud update module 340 can request the information from the cloud leader 604 and the cloud leader 604 can provide the properties of the vehicular micro cloud 120 as listed above.
The vehicular micro cloud adjustment system 270, or more specifically the vehicular micro cloud update module 340 can determine which adjustment to the one or more properties of the existing vehicular micro cloud 120 can address the impact. In this case, the impact is traffic congestion which can lead to safety risks such as a risk of additional collisions. The vehicular micro cloud update module 340 can determine the properties that a vehicular micro cloud 120 can have to assist vehicles travelling through the environment. As an example, the vehicular micro cloud update module 340 can access a database that matches the impacts to the related properties of a vehicular micro cloud 120. As another example and as previously mentioned, the vehicular micro cloud update module 340 can apply any suitable algorithm to determine the properties of the vehicular micro cloud 120. In this example, the vehicular micro cloud update module 340 can determine the following properties—safety as the priority type, stationary as the mobility type, interdependent as the dependency type, on-demand as the origin type, hybrid as the communication type, vehicle collision as the reason, mitigate traffic congestion as the collaboration objective, and minimize safety risk as the optimization method.
The vehicular micro cloud adjustment system 270, or more specifically the vehicular micro cloud update module 340 can compare the original reason and the new reason. In this case, the vehicular micro cloud update module 340 can compare the original reason, which is traffic flow with the new reason, which is a vehicle collision, and can determine that the original reason and the new reason are different. In response to determining that the original reason and the new reason are different, the vehicular micro cloud update module 340 can update the properties of the existing cloud by transmitting a message to the cloud leader 604 to adjust the properties of the vehicular micro cloud 120. In this case, in response to receiving the message, the cloud leader 604 can adjust the dependency type from independent to interdependent. In this example and as shown in
A second non-limiting example of the operation of the vehicular micro cloud adjustment system 270 and/or one or more of the methods will now be described in relation to
In
The vehicular micro cloud adjustment system 270, or more specifically, the environment parameter determination module 320 can determine one or more parameters of the environment around the commuter vehicle 704 and the vehicles 702 proximate to the commuter vehicle 704. As shown in
The vehicular micro cloud adjustment system 270, or more specifically, the impact identification module 330 can identify an impact of the parameters of the environment on the vehicle(s) 702 associated with the existing vehicular micro cloud 120. In other words, the impact identification module 330 can identify the impact of the parameters of the environment on the vehicles 702 approaching the stopped commuter vehicle 704. The impact identification module 330 can determine that the impact can be traffic congestion based on the commuter vehicle 704 being stopped and blocking traffic, and the number of vehicles 702 travelling on the road towards the commuter vehicle 704. The impact identification module 330 can further determine that traffic congestion can increase the risk of a collision. As previously mentioned, the impact identification module 330 can use any suitable algorithm to determine the impact of the stopped commuter vehicle 704 on the vehicles 702 in the environment.
The vehicular micro cloud adjustment system 270, or more specifically the vehicular micro cloud update module 340 can identify one or more properties of the existing vehicular micro cloud 120. The vehicular micro cloud update module 340 can identify the properties by requesting the information from, as an example, the cloud leader. The vehicular micro cloud adjustment system 270, or more specifically the vehicular micro cloud update module 340 can determine which adjustment to the one or more properties of the existing vehicular micro cloud 120 can address the impact. In this case, the impact is traffic congestion which can lead to safety risks such as a risk of a collision between vehicles or a collision between a vehicle and a passenger boarding or deboarding the commuter vehicle. As previously mentioned, the vehicular micro cloud update module 340 can determine the properties that a vehicular micro cloud 120 can have to assist vehicles travelling through the environment. In this example, the vehicular micro cloud update module 340 can determine the following properties—safety as the priority type, stationary as the mobility type, interdependent as the dependency type, on-demand as the origin type, ad-hoc as the communication type, stopped commuter vehicle as the reason, improve environment awareness as the collaboration objective, and minimize safety risk as the optimization method.
The vehicular micro cloud adjustment system 270, or more specifically the vehicular micro cloud update module 340 can compare the original reason and the new reason. In this case, the vehicular micro cloud update module 340 can compare the original reason, which is safety and comfort for a mobile commuter vehicle with the new reason, which is safety around a stopped commuter vehicle 704, and can determine that the original reason and the new reason are different. In response to determining that the original reason and the new reason are different, the vehicular micro cloud update module 340 can update the properties of the existing cloud by transmitting a message to the cloud leader, which is the commuter vehicle 704 in this case, to adjust the properties of the vehicular micro cloud 120. In response to receiving the message, the commuter vehicle 704 can adjust the mobility type of the vehicular micro cloud 120 from mobile to stationary. In this example, an approaching vehicle 702 near the commuter vehicle 704 can detect that there is a stopped commuter vehicle 704 using vehicle sensors 221. The approaching vehicle 702 can instruct other approaching vehicles to form vehicular micro clouds 720 that are interdependent. When the approaching vehicles form interdependent vehicular micro clouds 720 and the existing vehicular micro cloud 120 adjusts from an independent dependency type to an interdependent dependency type, the existing vehicular micro cloud 120 and the newly formed vehicular micro clouds 720, as well as the vehicle members 702 are able to collaborate and exchange information. As such the commuter vehicle 704 of the existing vehicular micro cloud 120 can send updates about the location of the commuter vehicle 704 and how long the commuter vehicle 704 intends to be stopped to the newly formed vehicular micro clouds 720.
It will be appreciated that arrangements described herein can provide numerous benefits, including one or more of the benefits mentioned herein.

In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
The terms “a” and “an,” as used herein, are defined as one or more than one. The term “plurality,” as used herein, is defined as two or more than two. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and/or “having,” as used herein, are defined as comprising (i.e., open language). The phrase “at least one of . . . and . . . ” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. As an example, the phrase “at least one of A, B, and C” includes A only, B only, C only, or any combination thereof (e.g., AB, AC, BC or ABC).
Aspects herein can be embodied in other forms without departing from the spirit or essential attributes thereof. Accordingly, reference should be made to the following claims, rather than to the foregoing specification, as indicating the scope hereof.
