1. An electronic maneuver detection system in real time based on dynamically measured telematics data, wherein driver behaviors and operational parameters are measured and discriminated based on automatically individuated driver maneuvers within various measured vehicle trajectories, and wherein an output signal is generated performed based upon derived risk measure parameters and/or crash attitude measure parameters, the system comprising:

  • circuitry configured tocapture data from mobile telematics devices associated with a plurality of motor vehicles, the telematics devices comprising one or more wireless connections, wherein, for providing the wireless connection, each of the telematics devices acts as a wireless node within a corresponding data transmission network by antenna connections of the telematics device, wherein each of the telematics devices is an integral part of a mobile phone device and connected to a monitoring cellular mobile node application of the mobile phone device, and wherein each of the telematics devices comprises a sensor configured to capture the data as usage-based and/or user-based and/or operation-based telematics data of the motor vehicle and/or users, the telematics sensor, at a minimum, comprising an accelerometer sensor and a global positioning system (GPS) sensor and/or a gyroscope sensor;

    implement a dynamic, functional aggregation-based telematics circuit to which the plurality of mobile telematics devices are connected, wherein a data link is set between the dynamic, functional aggregation-based telematics circuit transmitting at least the captured usage-based and/or user-based and/or operation-based telematics data from the mobile telematics devices to the dynamic, functional aggregation-based telematics circuit;

    for driver maneuver identification, match sequential patterns of the captured usage-based and/or user-based and/or operation-based telematics data with searchable predefined measuring parameter sets of driving maneuvers by the dynamic, functional aggregation-based telematics circuit, wherein the dynamic, functional aggregation-based telematics circuit stores the searchable predefined driving maneuvers, wherein each driving maneuver is composed of a plurality of hierarchically structured operation-measuring parameter sets, wherein a specific operation or driving feature of a vehicle is separately identifiable and triggerable based on a corresponding operation parameter set, wherein each driving maneuver is composed of sequential patterns of operations or driving features by the hierarchical structure which are each extractable and measurable by the measuring telematics parameters exhibiting during the lifespan of a driving maneuver, and wherein sequential patterns of the captured usage-based and/or user-based and/or operation-based telematics data are matched with the searchable predefined measuring parameter sets of driving maneuvers by the dynamic, functional aggregation-based telematics circuit;

    for pattern template identification, store searchable predefined measuring parameter pattern templates of driving maneuvers, wherein each single driving maneuver is composed of a plurality of prototypical parameter patterns, wherein an individuated time interval is measured spanning the duration of a captured maneuver pattern by the telematics circuit, wherein the measured individuated time interval is used as a time index for extracting the portions of features effectively corresponding to a selected maneuver, wherein, for each captured maneuver pattern and each operation or feature, a similarity measurement of the detected operation and/or feature profiles is performed ranging over possible trajectories used as a benchmark and highly correlated operations or features are selected; and

    automatically individuate captured driver maneuvers within the various car trajectories provided by the matched searchable measuring parameter sets of driving maneuvers and the measured pattern templates of driving maneuvers, wherein, for two temporal sequences, within the captured usage-based and/or user-based and/or operation-based telematics data, a temporal-variation independent measuring parameter is measured, each time, by the dynamic, functional aggregation-based telematics circuit, wherein the dynamic, functional aggregation-based telematics circuit provides an optimal match between the two temporal sequences by varying the temporal sequences.
