ABSTRACT:
The embodiments of the control system for automatic transmissions for electric automobiles disclosed includes an electric motor drive control, a changeover device, a speed change control, a torque setting device, a transmitting force detector, and a motor output torque detector. The present control system enables the fluctuation of the transmission output shaft torque to be counteracted by the DC electric motor output torque for realizing extremely smooth transmission of motive power.
