It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

As described above, the damage rate of the vehicles remains high. The damaged vehicle can cause a variety of problems. For example, the damaged vehicle can significantly reduce the user experiences and the safety in using the vehicle. Additionally, it is hard for the sharing vehicle service providers to locate the damaged vehicle, and to repair the damaged vehicle in an appropriate time, thus increasing the maintenance costs.
To detect the damaged vehicle, one traditional approach is to install various sensors on the vehicle, but the costs and power consumption of these sensors are rather high. Another traditional approach is that the user who uses or attempts to use the vehicle can report the damage of the vehicle to the sharing vehicle service providers. However, the sharing vehicle service providers cannot control the behavior of the user, for example, the user may report a false damage, or may not report the damage.
In order to at least partially solve one or more of the above problems and other potential problems, example embodiments of the present disclosure propose a solution for managing a shared vehicle. In the solution, first information about a user is obtained. The first information indicates a speed of at least one vehicle used by the user. Additionally, or alternatively, the first information may indicate other proper factors, such as a health condition, remaining life or the like of at least one vehicle used by the user.
A target vehicle is determined from the at least one vehicle based on the first information. Second information about the target vehicle is determined. The second information indicates respective speeds of the target vehicle moving at a plurality of time intervals. An abnormal state of the target vehicle is detected based on the second information. The abnormal state indicates that a malfunction occurs in the target vehicle.
As such, a potentially problematic vehicle can be automatically identified. In this way, the costs for detecting the problematic vehicle is reduced, and the accuracy and efficiency detecting the problematic vehicle is improved, thus improving the user experience of the shared vehicle service.
Reference is now made to
The vehicle 410 can collect information associated with use of the vehicle 410 by the user at a time interval and provide the collected information to the computer system/server 12. The information may include, but not limited to, a moving distance 420, a length of the time interval 430, a road condition 440 and a weather condition 450. For example, the information may also include a speed of the vehicle 410 used by the user. The moving distance 420 indicates the distance that the vehicle 410 used by the user moves.
The length of the time interval 430 indicates the length of the time interval when the vehicle 410 is used by the user. In some embodiments, the time interval may be the entire time when the vehicle 410 is used by the user. Additionally, or alternatively, the time interval may exclude the invalid time. The invalid time indicates the time that the vehicle 410 is not moving, for example, the time when the user using the vehicle 410 waits for the traffic light, the time when the user using the vehicle 410 stops and engages in other activities, such as making a call.
The road condition indicates the condition of the road on which the vehicle 410 used by the user moves. In some embodiments, the road condition may indicate a degree of congestion of the road, for example, a road having a serious traffic jam may have a high degree of congestion. Additionally, or alternatively, the road condition may indicate a type of road, for example, a mountain road, a waterlogged road, a muddy road, a flat road in the city or the like.
The weather condition indicates the condition of the weather when the vehicle 410 is used by the user. In some embodiments, the weather condition may indicate a type of weather, such as sunny, rainy, snowy or the like. Additionally, or alternatively, the weather condition may indicate the season, for example, the spring, summer, autumn or winter. Furthermore, the weather condition may indicate the temperature.
In some embodiments, the route that the vehicle 410 used by the user moves can be divided into a plurality of segments. For example, the route may be divided into a plurality of segments based on the time, the distance or any other appropriate manner. As a specific example, the route between two traffic lights may be defined as a segment. In this case, the moving distance 420, the length of the time interval 430, the road condition 440 and the weather condition 450 may relate to a certain segment.
The computer system/server 12 may determine first information about the user based on the information obtained from the vehicle 410. The first information indicates a speed of at least one vehicle used by the user. In some embodiments, the speed of the vehicle 410 may be determined simply based on the moving distance 420 and the length of the time interval 430. For example, the speed of the vehicle 410 may be calculated by dividing the moving distance 420 by the length of the time interval 430. Alternatively, when the vehicle 410 provides its speed to the computer system/server 12 directly, the computer system/server 12 may determine the speed of the vehicle 410 directly.
In some embodiments, the speed of the vehicle 410 may also be determined based on the other factors, such as the road condition 440 and the weather condition 450. For example, the computer system/server 12 may assign different weight to different road conditions and weather conditions and multiply the actual speed by the weight so as to determine an adjusted speed which accounts for the road condition 440 and the weather condition 450.
For example, assume that the weight for the road condition indicating a flat road in the city is 1, and the actual speed is 15 km/h, in this case, the adjusted speed is 1*15=15 km/h. In contrast, assume that the weight for the road condition indicating a mountain road is set to 1.3, and the actual speed is 11 km/h, the adjusted speed is 1.3*11=14.3 km/h. As such, the effects caused by the other factors can be eliminated in detecting the abnormal state of the vehicle 410.
Movement of the vehicle can be monitored using one or more methods. For example, the user's cellular phone can be employed, the vehicle can have a sensor(s), transmitters, GPS signaling or other mechanisms to monitor the speed, position, etc.
For example, at the time interval i1, the user A may use a first vehicle, in this case, the point indicates the speed of the first vehicle used by the user A at the time interval i1. At the time interval i2, the user A may use a second vehicle, in this case, the point indicates the speed of the second vehicle used by the user A at the time interval i2.
Similarly,
Additionally,
The computer system/server 12 may determine a target vehicle from the at least one vehicle based on the first information 510. Normally, a user has a rather fixed speed in using a vehicle 410. In this case, in some embodiments, the computer system/server 12 may determine a user reference speed range. When a speed of a vehicle 410 exceeds or otherwise falls out of the user reference speed range, such vehicle 410 may be determined as the target vehicle.
For example, the computer system/server 12 may determine a user reference speed based on historical speeds of vehicles used by the user. The user reference speed may be the average value of the historical speeds of vehicles. Then, the computer system/server 12 may determine the user reference speed range based on the user reference speed and a predetermined value. For example, the predetermined value may be a variance of the historical speeds of vehicles. In this case, the upper limit of the user reference speed range may be calculated by adding the user reference speed and the variance, while the lower limit of the user reference speed range may be calculated by subtracting the variance from the user reference speed. Alternatively, the user reference speed and the variance can be set to be any appropriate value or predetermined by the service provider or the user.
Then, the computer system/server 12 may determine the target vehicle based on the user reference speed range. For example, if a speed of a vehicle 410 exceeds or falls out of the user reference speed range, in other words, if the difference between the user reference speed and a speed of a vehicle 410 exceeds a predetermined threshold difference, which can be for example the variance, the vehicle 410 may be determined as the target vehicle.

Returning to
In some embodiments, the speed of the vehicle 410 may be determined simply based on the moving distance 420 and the length of the time interval 430. For example, the speed of the vehicle 410 may be calculated by dividing the moving distance 420 by the length of the time interval 430. Alternatively, when the vehicle 410 provides its speed to the computer system/server 12 directly, the computer system/server 12 may determine the speed of the vehicle 410 directly.
In some embodiments, the speed of the vehicle 410 may also be determined based on the other factors, such as the road condition 440 and the weather condition 450. For example, the computer system/server 12 may assign different weight to different road conditions and weather conditions, and multiply the actual speed by the weight so as to determine an adjusted speed which accounts for the road condition 440 and the weather condition 450.
For example, at the time interval i2, the target vehicle may be used by the user A as shown in
Then, the computer system/server 12 may detect an abnormal state of the target vehicle based on the second information 610. The abnormal state indicates that a malfunction occurs in the target vehicle. Normally, a vehicle 410 has a rather fixed speed. In this case, in some embodiments, the computer system/server 12 may determine a normal speed range. If the speeds of the target vehicle continuously exceed the normal speed range, it may be determined that a malfunction occurs in the target vehicle.
As such, it is possible to reduce the probability that a vehicle 410 is determined to be malfunctioning because of a speed of the vehicle 410 used by a user accidentally exceeds the user reference speed, and thus improving the accuracy of the vehicle malfunction detection.
For example, the computer system/server 12 may determine a vehicle reference speed based on historical speeds of the target vehicle. The vehicle reference speed may be the average value of the historical speeds of the target vehicle moving at a plurality of time intervals. Additionally, the computer system/server 12 may determine a variance of the historical speeds of the target vehicle. In this case, the normal speed range may be determined based on the vehicle reference speed and the variance. For example, the upper limit of the normal speed range may be calculated by adding the vehicle reference speed and the variance, while the lower limit of the vehicle speed range may be calculated by subtracting the variance from the vehicle reference speed.
Alternatively, the vehicle reference speed can be set to be any appropriate value or predetermined by the service provider. For example, since it can be assumed that a new vehicle does not have any malfunction, the vehicle reference speed may be set to be the speed of the new vehicle. In addition, the variance can also be set to be any appropriate value or predetermined by the service provider, for example, the variance of the speeds of a predetermined number of new vehicles. As shown in
In some embodiments, the computer system/server 12 may determine a pattern of the respective speeds of the target vehicle moving at the plurality of time intervals exceed the normal speed range, and detect the abnormal state based on the pattern. For example, as shown in
For example, since the speeds of the target vehicle at a plurality of time intervals after the time interval indicated by the point 640 exceed the normal speed range, the target vehicle corresponding to the point 540 is determined to be the target vehicle. It is to be understood that, the point 540 as shown in
Alternatively or additionally, since the speeds of the vehicles 410 on the same route at the same time are more or less the same, the computer system/server 12 may also compare the speed of the target vehicle to the speeds of the other vehicles moving on the same route at the same time interval.
For example, the target vehicle may always be used at the peak hour with a heavily traffic congestion, and the speed of the target vehicle may continuously exceed the normal speed range. The computer system/server 12 may determine a route reference speed which may be, for example, the average value of the speeds of all the vehicles moving on the same route at the same time interval. Then, the computer system/server 12 may determine whether a difference between the speed of the target vehicle and the route reference speed exceeds a predetermined threshold. If the difference exceeds the predetermined threshold, the target vehicle may be determined to be malfunctioning. In this way, the accuracy of detecting a malfunctioning vehicle can be further increased.
As such, an abnormal state of a vehicle can be automatically detected. In this way, it is possible to reduce the costs for detecting whether a malfunction occurs in the vehicle, and improve the accuracy and efficiency in determining the problematic vehicle.
At 710, the computer system/server 12 obtains first information 510 about a user. The first information 510 indicates a speed of at least one vehicle used by the user. In some embodiments, the computer system/server 12 may obtain information associated with use of the at least one vehicle by the user at a time interval. The information includes, for example, but not limited to, a moving distance 420 indicating the distance moved in the time interval, a length 430 of the time interval, a road condition 440 in the time interval, a weather condition 450 in the time interval, and/or the like. Then, the computer system/server 12 may determine the first information 510 based on the obtained information.
At 720, the computer system/server 12 determines a target vehicle from the at least one vehicle based on the first information 510. In some embodiments, the computer system/server 12 may determine a user reference speed based on historical speeds of vehicles 410 used by the user. For example, the user reference speed may be determined based on an average of the respective speeds of the vehicles used by the user at the plurality of time intervals.
Then, the computer system/server 12 may determine a difference between the user reference speed and a speed of a candidate vehicle. The candidate vehicle is selected from the at least one vehicle used by the user. When the difference exceeds a threshold difference, the computer system/server 12 may determine the candidate vehicle as the target vehicle.
At 730, the computer system/server 12 determines second information 610 about the target vehicle. The second information 610 indicates respective speeds of the target vehicle moving at a plurality of time intervals. In some embodiments, the computer system/server 12 may obtain information associated with moving of the target vehicle at the plurality of time intervals. The information includes, for example, but not limited to, a moving distance of each of the plurality of time intervals 420, a length of each of the plurality of time intervals 430, a road condition of each of the plurality of time intervals 440 and a weather condition of each of the plurality of time intervals 450. Then, the computer system/server 12 may determine the second information 610 based on the obtained information.
At 740, the computer system/server 12 detects an abnormal state of the target vehicle based on the second information 610. The abnormal state indicates that a malfunction occurs in the target vehicle. In some embodiments, the computer system/server 12 may determine a pattern of differences between the respective speeds of the target vehicle moving at the plurality of time intervals and a vehicle reference speed. For example, the computer system/server 12 may determine the vehicle reference speed based on an average of the respective speeds of the target vehicle moving at the plurality of time intervals. Alternatively, the computer system/server 12 may determine the vehicle reference speed based on the speed of the new vehicle. Then, the computer system/server 12 may detect the abnormal state based on the pattern.
For example, the computer system/server 12 may determine, based on the pattern, whether a speed of the target vehicle during a predetermined time period is out of a normal speed range. In some embodiments, the predetermined time period may include the time interval at which the difference between the user reference speed and the speed of the target vehicle exceeds the threshold difference. For example, the predetermined time period may surround that time interval.
Then, when the speed of the target vehicle is determined to be out of the normal speed range, the computer system/server 12 may determine that that a malfunction occurs in the target vehicle.
As such, a potentially problematic vehicle can be automatically identified. In this way, the costs for detecting the problematic vehicle are reduced, and the accuracy and efficiency detecting the problematic vehicle is improved, thus improving the user experience of the sharing vehicle.
At 810, the computer system/server 12 obtains information about a target vehicle identified with an abnormal state.
At 820, the computer system/server 12 activates a method to locate the vehicle, e.g., employs global positioning, a homing signal, video or other methods from the vehicle or other sources to identify a current location of the vehicle.
At 830, the abnormal state indicates that a malfunction occurs in the target vehicle so once the vehicle is located, the target vehicle is repaired or removed from service. As such, a potentially problematic vehicle can be identified and fixed. In this way, the user experience of the sharing vehicle is enhanced.

The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. 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). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
