Abstract: The purpose of the present invention is to provide a technology for updating a recognition model so that even if there were errors in recognition of an unknown scene or the like, the scene can be recognized quickly. The present invention is provided with a data analysis unit 11 that, on the basis of data from an outside recognition unit 32 provided to a vehicle, acquires from among previously stored recognition models a model approximate to a recognition model recognized by the outside recognition unit 32, and that reproduces the acquired model in the form of computer graphics images. The data analysis unit 11 is provided with: a difference extraction unit 114 that compares the reproduced computer graphics images and data from the outside recognition unit 32 and extracts a difference therebetween; an object recognition unit 116 that recognizes an object relating to the difference extracted by the difference extraction unit 114; and a scene reconfiguration unit 117 that creates computer graphics images having the object recognized by the recognition unit 116 reflected therein.

Abstract: A reporting device that is connected to at least one vehicle, which is controlled based on a result of recognition by an outside recognizer, via a network provides the vehicle with information on a possibility of a failure in outside recognition on the basis of a condition under which a failure in outside recognition has occurred previously. Preliminarily, if a failure such as non-detection or erroneous detection occurs due to an outside recognizer of a connected car, the abnormality is stored while being linked with an external traveling environment such as the position of the vehicle or a weather.

Abstract: An object of the present invention is to grasp information regarding the state of a vehicle (for example, an automobile) that cannot be obtained from an OBD, and to monitor the state of the vehicle. An aspect of the present invention includes: a state estimation unit that estimates the state quantities of a monitoring-target vehicle based on sensor data obtained from sensors mounted on a mobile information terminal in the monitoring-target vehicle using a state estimation device that has learned the relationship between sensor data obtained from sensors mounted on a mobile information terminal in an arbitrary vehicle and state quantities of the arbitrary vehicle in advance; a state evaluation unit that executes evaluation regarding a state of the monitoring-target vehicle on the basis of the estimated state quantities of the monitoring-target vehicle; and an evaluation result output unit that outputs a result of the evaluation.

Abstract: To provide an anomality candidate information analysis apparatus capable of early confirming that an unexpected anomality occurs in a monitoring object such as a vehicle. There is provided an anomality candidate information analysis apparatus for analyzing anomality candidate information of a vehicle that is a monitoring object. The anomality candidate information analysis apparatus includes a storage unit and an analysis unit. The storage unit stores monitoring object information regarding the vehicle, environment information regarding an environment around the vehicle, operator information regarding an operator of the vehicle, and anomality candidate information detected in the vehicle in association with each other. The analysis unit extracts the anomality candidate information associated with the monitoring object information, the environment information, and the operator information, and analyzes a dependence degree of the anomality candidate information to the environment information and the operator information.

Abstract: A system for guiding a driver to an ideal driving pattern in order to eliminate dependency on the driver's driving pattern in a fault diagnosis of an automobile part based on automobile running data, even if the driver's driving pattern is far from the ideal driving pattern. The system comprises a fault diagnosis support device equipped with: a diagnosis model selector for outputting a diagnosis model in which, for a feature value used for an examination of an automobile part, an available range available for making a diagnosis and a reference point are stipulated; a driver model generator generating, as a representative point of the feature value that corresponds to a driver's driving pattern; and a recommendation model generator generating, if the representative point is outside the available range, a recommendation model in which a boundary of the available range is set as a recommendation point.
