Problems solved by technology
Such a system can be used to input diagnostic and prognostic data for analysis; however, such a centralized system would require significant processing power and be expensive to process
Also, a communication link using cellular communication between the vehicle and the backend server would be costly and have limited bandwidth
As a result, attempting to send diagnostic and prognostic data to such a larger group of vehicles for analysis will result in possible overloading of both the cellular system and backend servers and the overall system will have scalability issues

Embodiment Construction
[0042] exist figure 1 A traffic flow diagram showing a host vehicle 10 and a remote vehicle 12 is shown generally in . The remote vehicle 12 has the capability to communicate with the host vehicle 10, which is referred to as vehicle-to-vehicle (V2V) communication. The host vehicle 10 and the remote vehicle 12 send wireless messages to each other over respective inter-vehicle communication networks (eg, DSRC).
[0043] Vehicle-to-vehicle (V2V) wireless messages passed between vehicles can be sent as standard messages. The wireless messages include data related to the vehicle's operating conditions, environmental awareness conditions, and vehicle dynamics / dynamic parameters. An advantage of embodiments described herein is that a vehicle can communicate diagnostic and prognostic (D&P) data about its own vehicle for comparison purposes. This allows each vehicle to independently process and compare data collected from remote vehicles with its own data to determine if any of its ...

A method is provided for processing and analyzing diagnostic and prognostic data in a vehicle ad-hoc network. Diagnostic and prognostic data is exchanged between a host vehicle and remote vehicles in the vehicle ad-hoc network. The received diagnostic and prognostic data is stored in a memory of the host vehicle. Redundancy is eliminated in the received diagnostic and prognostic data. The diagnostic and prognostic data is assigned to clusters. Anomalies are detected in the stored data utilizing clustering techniques that determine whether a cluster of diagnostic and prognostic data formed from the host vehicle substantially deviates from the clusters of diagnostic and prognostic data formed from the remote vehicles. A driver of a vehicle is notified if the cluster data from a host vehicle deviates significantly from the clusters from the remote vehicles.
Description
technical field [0001] Embodiments generally relate to vehicle-to-vehicle communication ad-hoc networks. Background technique [0002] In vehicle-to-vehicle (V2V) communication, vehicles usually communicate with centralized backend servers through base stations to provide vehicle information for analysis. Backend servers are capable of storing and processing data for a large number of vehicles within a city or other geographic location. Typically, such communications are performed using cellular service. Such a system can be used to input diagnostic and prognostic data for analysis; however, such a centralized system would require a large amount of processing power and be expensive to process. Additionally, a communication link using cellular communication between the vehicle and the backend server would be costly and have limited bandwidth. As a result, attempting to send diagnostic and prognostic data for analysis to such a larger group of vehicles would result in possi...
