Transmission control system for controlling a main transmission speed changing pattern relative to a subtransmission speed changing ratio
A transmission control device for controlling a transmission system having speed changing ratios and composed of a main transmission and a sub transmission connected to the output shaft of the main transmission is described comprising: (a) electronic control means for receiving outputs from a plurality of sensors for sensing the running state of vehicle; (b) speed changing mechanism driving means controlled by output signals from an electronic controller so as to drive and control the speed changing mechanisms in the main transmission and the sub transmission; (c) speed changing ratio detecting means for detecting the speed changing ratio selected by the speed changing mechanism of the sub transmission; and (d) main transmission speed changing pattern control means for controlling the speed changing pattern of the main transmission in accordance with output signals from the speed changing ratio detecting means.
