Abstract
Drive systems or powertrains including transmissions for electric and hybrid electric vehicles are provided. In some embodiments, dynamic, 2-position linear motor, one-way clutches are provided. In other embodiments, 3-position linear motor, 2-way clutches are provided. In a fixed speed ratio operating mode of an electric vehicle powertrain, torque values for two electric motors are determined by control logic to optimize overall efficiency of the motors. In a fixed torque ratio operating mode of the powertrain, speed values for the two motors are determined to optimize overall efficiency. A hybrid electric powertrain of at least one embodiment uses the optimized electric vehicle powertrain, an engine and the one-way and 2-way clutches to obtain a highly optimized hybrid powertrain.
