Abstract: PURPOSE: To attain an automatic frequency control system for compensating error synchronism and correctly demodulating a received signal even when a large angular frequency deviation is included in the received signal. CONSTITUTION: In a detection means 1 consisting of an orthogonal detector 11, an A/D converter 12, a complex/angle converter 13, and a delay detector 14, a band limit PSK signal 401 is converted into in-phase and orthogonal component complex base band signals 402, 403 by the detector 11, the signals 402, 403 are digitized to complex digital signals 404, 405 by the converter 12 and then the signals 404, 405 are converted into phase (angular) data 406 by the converter 13. A phase difference deviation of phase difference data 407 having a phase difference from one symbol ago is corrected by the feedback of hard judging data 409 generated by an automatic frequency controller 21 and a judging device 22 in a phase deviation correcting means 2 to obtain demodulated data 408.  In an error synchronism compensating means consisting of a known data pattern correlator 31 and a data converter 32, data are converted in accordance with a known data detection signal 410 generated by finding out correlation between the data 409 and a previously set reference pattern to select required output data 411.

A shift control part 26 of the control unit 25 scans the shift pattern for acceleration and emits a shift signal to generate shifting-down to No.3 or No.2 speed in accordance with the drop condition of the car speed V as the throttle opening increase side shift position is dislocated to the low speed side, and acceleration is made by increasing the drive force with this gear ratio. Shifting-up is obtained soon after rising of the car speed, and the signal is turned off at V Vs.
