  • Systems and methods for implementing dynamic operating modes and control policies for hybrid electric vehicles
    Patent number: 9849869
    Abstract: Systems and/or methods for controlling dual motor-dual clutch powertrains for HEV and PHEV vehicles are disclosed. In one embodiment, a method is disclosed comprising: determining the state of charge (SOC) of said batteries; determining the speed of the vehicle; if the SOC is greater than a given first threshold, selecting a charge-depleting operational mode of said vehicle; during operation of said vehicle, if the SOC is less than a given second threshold, selecting a charge-sustaining operating mode of said vehicle. In another embodiment, a system having a controller that operates the powertrain according to various embodiments is disclosed.

  • Wind Turbine Systems Using Continuously Variable Transmissions and Controls
    Publication number: 20100308586
    Abstract: A wind turbine system is disclosed comprising: a plurality of turbine blades; a continuously variable transmission coupled to said plurality of turbine blades; a generator coupled to said continuously variable transmission; wherein said generator generates electricity and outputs said electricity to a load/grid; and a controller providing control signals as a filtered function of power to said continuously variable transmission. The controller of said wind turbine system may also continuously maintain the parameter dP/dR substantially zero where P is power and R is the ratio of the transmission.
