摘要： A system and method for providing autonomous and remote vehicle maintenance and repair. The system employs an on-board diagnosis and prognosis module that monitors one or more vehicle buses to identify trouble codes and other information indicating a vehicle problem. The on-board module causes a telematic device on the vehicle to broadcast a message including a problem code that identifies the problem the vehicle is having. A remote repair center may receive the message and may identify a software upgrade patch associated with the problem that can be transmitted to the vehicle to upgrade its software to correct the problem. Also, the message may be received by another vehicle that is part of a broadcast network that has previously received the software upgrade patch to fix a problem on that vehicle, where the receiving vehicle may transmit the software upgrade patch to the vehicle having the problem.

摘要： A system and method for determining the root cause of a fault in a vehicle system, sub-system or component using models and observations. In one embodiment, a hierarchical tree is employed to combine trouble or diagnostic codes from multiple sub-systems and components to get a confidence estimate of whether a certain diagnostic code is accurately giving an indication of problem with a particular sub-system or component. In another embodiment, a hierarchical diagnosis network is employed that relies on the theory of hierarchical information whereby at any level of the network only the required abstracted information is being used for decision making. In another embodiment, a graph-based diagnosis and prognosis system is employed that includes a plurality of nodes interconnected by information pathways. The nodes are fault diagnosis and fault prognosis nodes for components or sub-systems, and contain fault and state-of-health diagnosis and reasoning modules.

摘要： A system and method for providing proactive vehicle system management and maintenance using diagnostic and prognostic information. Vehicle information is collected from vehicle sensors and/or sub-systems by an on-board module on the vehicle and/or at a remote facility where the information is wirelessly transmitted to the remote facility. The collected information is analyzed to determine the health of various systems, sub-systems and components so that the remaining useful life of the systems, sub-systems and components can be predicted. By utilizing the diagnostic and prognostic information, a vehicle control strategy can be reconfigured to minimize customer impact. Further, if a software problem is detected, temporary or permanent software fixes can be provided automatically and remotely through a remote service garage.

摘要： A system and method for providing real-time traffic information using a wireless vehicle-to-vehicle communications network. A vehicle includes a plurality of sensors that detect other vehicles around the vehicle. The wireless communications system on the vehicle uses the sensor signals to calculate a traffic condition index that identifies traffic information around the vehicle. The vehicle broadcasts the traffic condition index to other vehicles and/or road side infrastructure units that can present the information to the vehicle driver, such as in a navigation system, and/or rebroadcast the traffic information to other vehicles. The traffic condition index can be calculated using the speed of the surrounding vehicles, posted speed limits, the distance between the surrounding vehicles and the traffic density of the surrounding vehicles.

摘要： A method for estimating the maximum tire/road surface coefficient of friction for a vehicle that includes actively inducing a small amount of acceleration or deceleration to the front wheels or the rear wheels of the vehicle and inducing a corresponding and opposite amount of acceleration or deceleration to the other of the front wheels or the rear wheels of the vehicle so that the acceleration and deceleration cancel each other and the perceived speed of the vehicle does not change. The tire/road surface coefficient of friction and a wheel-slip ratio can be used to determine a road surface condition.
