| 20100245124 | E85 GAS STATION LOCATOR APPLICATIONS USING V2X PEER-TO-PEER SOCIAL NETWORKING - A system and method for wirelessly exchanging information concerning the location of E85 gas stations between E85 vehicles. The method includes transmitting messages from an E85 gas station that identifies the location of the E85 gas station, the time of the transmission and the price of the E85 gas, and receiving the messages by E85 vehicles that pass within a certain distance of the E85 gas station. The method also includes identifying that two E85 vehicles pass close to each other, where the vehicles periodically broadcast an E85 beacon identifying them as E85 vehicles. When two E85 vehicles are identified, the vehicles exchange information concerning a list of the E85 gas stations that they have stored from messages received from E85 gas stations and/or other E85 vehicles. The two vehicles update their lists to include those E85 gas stations that one vehicle may have that the other does not. | 09-30-2010 |
| 20100248618 | USING V2X IN-NETWORK SESSION MAINTENANCE PROTOCOLS TO ENABLE INSTANT CHATTING APPLICATIONS - A system and method for allowing vehicle occupants to wirelessly chat with each other over a DSRC channel. A vehicle occupant may initiate a chatting session by wirelessly transmitting a request to speak with an occupant of another vehicle in its vicinity on a certain topic in a multi-hop manner. If the request is accepted by the occupant of another vehicle to enter into a chatting session on that topic, a wireless communications link is established between the two vehicles, where messages may be transmitted through other intermediate vehicles. The chatting session is maintained by monitoring the signal strength of the links between the vehicles in the chain of vehicles and new links are re-established if any of the existing links fail. | 09-30-2010 |
| 20100250106 | USING V2X-BASED IN-NETWORK MESSAGE GENERATION, AGGREGATION, DISTRIBUTION AND PROCESSING PROTOCOLS TO ENABLE ROAD HAZARD CONDITION WARNING APPLICATIONS - A method for providing messages indicating potential hazardous road conditions using a wireless communications network. Vehicles using the network include sensors that are able to detect various potentially hazardous road conditions, such as rain, fog, icy road conditions, traffic congestion, etc. A plurality of vehicles that detect a specific road condition provide a confidence value that the condition exists. The confidence value is then aggregated by the vehicles with the confidence value of the detected condition from the other vehicles to provide an aggregated result that identifies the probability that the detected road condition is occurring. The aggregated result is then transmitted to other vehicles approaching the road condition, possibly in a multi-hop manner. Alternately, the confidence value from all of the vehicles that detect the condition can be transmitted to approaching vehicles who will provide the aggregated result identifying the potential that the condition exists. | 09-30-2010 |
| 20100250346 | USING V2X IN-NETWORK MESSAGE DISTRIBUTION AND PROCESSING PROTOCOLS TO ENABLE GEO-SERVICE ADVERTISEMENT APPLICATIONS - A system and method for providing geo-service advertising messages using a wireless vehicle-to-infrastructure (V2X) communications network. Messages are transmitted from a business that identify the type of business, the name of the business and the location of the business, which are received by vehicles traveling within a certain distance of the business. The messages can be rebroadcast by the vehicles receiving the messages from the business to other vehicles either in a multi-hop information routing manner or in a delay-tolerant network information dissemination fashion so that the messages are sent to a wider area, but within a predetermined geographic area and with a predetermined time. If a particular user of the system wishes to learn about a particular business or type of business, he can activate the system so that the messages being sent between the vehicles and from the businesses can be displayed to the user for his use. | 09-30-2010 |
| 20110140968 | A LEAN V2X SECURITY PROCESSING STRATEGY USING KINEMATICS INFORMATION OF VEHICLES - A vehicle-to-vehicle communication filtering system is provided to selectively process broadcast messages between a host vehicle and a remote vehicle. A processing unit evaluates a time-to-collision status between the host vehicle and the remote vehicle sending the message. The time-to-collision status is a function of a relative distance and a relative velocity between the host vehicle and the remote vehicle which are determined from data provided within a first portion of the message received from the remote vehicle. An attentive factor is assigned to each of the remote vehicles based on the time-to-collision with respect to each remote vehicle. The attentive factor identifies a proportion of messages broadcast from the remote vehicle to be targeted for security processing. Security processing of the message is performed based on a second portion of the message unless the attentive factor indicates the message should be ignored. | 06-16-2011 |
| 20110205943 | OPPORTUNISTIC DATA TRANSFER BETWEEN VEHICLES - A system and method for optimizing wireless vehicle to vehicle communications is configured to maximize the amount of data that can be transferred from one vehicle to another during a transient encounter by adaptively adjusting the message packet size and data modulation rate during an inter-vehicle communication session. | 08-25-2011 |
| 20110221901 | Adaptive Scene Rendering and V2X Video/Image Sharing - A method is provided for video sharing in a vehicle-to-entity communication system. Video data is captured by an image capture device of an event remote from a source entity. A spatial relationship is determined between a location corresponding to the captured event and a location of a remote vehicle. A temporal relationship is determined between a time-stamp of the captured scene data and a current time. A utility value is determined as a function of the spatial relationship and the temporal relationship. A network utilization parameter of a communication network is determined for broadcasting and receiving the scene data. A selected level of compression is applied to the captured scene data as a function of the utility value and available bandwidth. The compressed scene data is transmitted from the source entity to the remote vehicle. | 09-15-2011 |
| 20110238259 | V2X-Connected Cooperative Diagnostic & Prognostic Applications in Vehicular AD HOC Networks - 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. | 09-29-2011 |
