  • Patent number: 8116945
    Abstract: A rotational angle correction controller controls generation of an inverse assist torque using the “phase deviation” due to the correction of the rotational angle ?, thereby performing the rotational angle correction control to smooth rotation of the motor during two phase drive. In addition, the rotational angle correction controller includes an oscillation detection part that detects the occurrence of oscillation in the steering system. When the level of the detected oscillation exceeds the predetermined level, the correction amount in the rotational angle correction control is reduced.

  • Patent number: 8116168
    Abstract: A migration method using hybrid one-way and full-way (HOF) wave equation propagation. The HOF method extrapolates seismic wavefields in less complex media with a one-way wave equation propagator and extrapolates seismic wavefields in extremely complex media with a full-way wave equation propagator. For prestack depth migration, the HOF extrapolates source-side and receiver-side wavefields independently. Frequency-space domain and time-space domain imaging conditions are applied to the one-way and the full-way extrapolated wavefields, respectively. A suitable amplitude matching factor is introduced to combine the one-way and full-way images. The HOF method is a cost-effective migration that produces superior image quality with less noises and less computational resources.

  • Patent number: 8098543
    Abstract: Various implementations described herein are directed to estimating stresses and elastic parameters in a formation based on seismic data. In one implementation, wide azimuth seismic data may be used to derive anisotropic elastic parameters. Furthermore, stresses may be calculated using a geomechanical earth model, followed by deriving anisotropic elastic parameters based on the calculated stresses. The anisotropic elastic parameters derived from the wide azimuth seismic data may then be used to modify the geomechanical earth model to improve the prediction of drilling parameters.

  • Patent number: 8086396
    Abstract: A method is provided for automatically controlling a first vehicle (follower vehicle) that is to follow a second vehicle (leader vehicle) in a desired manner with respect to movement of the second vehicle. In the follower vehicle, bearing and acceleration control inputs are generated based on data representing bearing and acceleration control inputs made at the leader vehicle and a position of the follower vehicle relative to the leader vehicle so as to mimic in the follower vehicle the bearing and acceleration control inputs made in the leader vehicle. Adjustments may be made to the control inputs applied in the follower vehicle based on deviation between the velocity of the follower vehicle and velocity of the leader velocity, and on deviation between estimated (actual) follow distance and lateral offset and target follow distance and lateral offset between the follower vehicle and the leader vehicle.

  • Patent number: 8086383
    Abstract: A control input for operating an actual vehicle actuator and a control input for operating a vehicle model are determined by an FB distribution law based on a difference between a reference state amount determined by a vehicle model and an actual state amount of an actual vehicle such that the state amount error is approximated to zero, and then an actuator device of the actual vehicle and the model vehicle are operated based on the control inputs. The FB distribution law determines a control input for operating the model such that a state amount error is approximated to zero while restraining a predetermined restriction object amount from deviating from a permissible range. A vehicle control device capable of enhancing robustness against disturbance factors or their changes while performing operation control of actuators that is as suited to behaviors of an actual vehicle as possible is provided.
