ABSTRACT:
A transmission control device in accordance with the present invention for controlling a transmission system which is composed of a main transmission and a sub transmission, has a first rotational speed detector which is disposed on the input side of the sub transmission and a second rotational speed detector which is disposed on the output side of the sub transmission, and is characterized in that one rotational speed detector is employed while the sub transmission is in a speed changing state and the other rotational speed detector is employed while the sub transmission is not in a speed changing state, thereby performing system control.
The transmission control device which has the above described construction is equipped with the first rotational speed detector for detecting the rotational speed output of the main transmission (the rotational speed input of the sub transmission) and the second rotational speed detector for detecting the rotational speed of the output shaft of the sub transmission, whereby the speed range of one transmission is capable of being positively controlled even while the other transmission is in a speed changing state.
