    摘要： Systems and techniques for simulated vehicle operation modeling with real vehicle profiles are described herein. In an example, a simulated vehicle modeling system is adapted to obtain a vehicle performance fingerprint, such as from a vehicle performance fingerprint that includes vehicle performance data collected from a unique vehicle while experiencing real world driving conditions. The simulated vehicle modeling system may be further adapted to present, in a driving simulator, a simulated driving experience with a simulated vehicle, such as for a simulated vehicle that is constructed based on the vehicle performance fingerprint. The simulated vehicle modeling system may be further adapted to update a set of driving directives for an autonomous vehicle based on the simulated driving experience and upload the set of driving directive to an autonomous vehicle.

    摘要： An example embodiment may involve determining, for a rotorcraft, input parameters including a disk diameter, a rotary velocity, a thrust coefficient, and a plurality of chord lengths across sections of a rotary wing of the rotorcraft; iteratively repeating until a convergence criterion is met: (i) determining an inflow to the rotary wing, (ii) based on the input parameters, defining a system of relationships based on vortex circulation strengths across the sections of the rotary wing, and (iii) solving the system of relationships to determine a distribution of lift across the sections of the rotary wing; and based on the distribution of lift and the plurality of chord lengths, determining local pitch angles for each of the sections of the rotary wing.

    摘要： Systems and methods are provided for simulating operation of an autonomous vehicle control system. Three dimensional multi-sensor data associated with a plurality of real-world drives in a sensor equipped vehicle is accessed. For a particular drive, the three dimensional multi-sensor data is reduced to a time series of two dimensional representations. The time series of two dimensional representations is classified into a sequence of states, where the sequence of states associated with the particular drive and the three dimensional multi-sensor data are stored in a computer-readable medium as a scenario. A query is received that identifies a state criteria, and the scenario is accessed based on the sequence of states matching the state criteria of the query. The three dimensional multi-sensor data of the scenario is provided to an autonomous driving system to simulate behavior of the autonomous driving system when faced with the scenario.

    摘要： A system and method therein for reducing the environmental impact of a vehicle is described. It describes obtaining, from the vehicle, actual operation and performance data of the vehicle; obtaining, from a simulator, simulated operation and performance data for the vehicle, wherein the simulated operation and performance data is at least partly based on actual operation and performance data of multiple vehicles; determining that an environmental impact based on the actual operation and performance data obtained from the vehicle is reduced compared to an environmental impact based on the simulated operation and performance data obtained from the simulator; and providing information indicating a reduction in environmental impact of the actual operation and performance data from the vehicle to a digital crypto-assets generating system such that an amount of digital crypto-assets corresponding to said reduction is able to be generated.
