    摘要： Electrically variable transmissions embodying the concepts of the present invention utilize two planetary gear subsets, two motor/generators and two clutches in the nature of torque transfer devices to effect input split, compound split, neutral and reverse modes of operation. Both planetary gear subsets may be simple, or one may be individually compounded. An electrical control member regulates power flow among an energy storage device and the two motor/generators. In either of two preferred embodiments the neutral mode of operation may be effected by releasing the two torque transfer devices, and the reverse mode of operation may be effected by reversing the magnetic polarity of one motor/generator. In addition, the two preferred embodiments allow a geared neutral as well as reverse to be effected by means of the differential gearing arrangement of the planetary gear subsets and other members of the transmissiom.
