Date Sep. 25, 1986.A control system for the automatic shifting of variable change speed transmission by an electronic control unit through which drive ratio change is determined in accordance with vehicle speed, instantaneous load demand and acceleration calculated from the speed of the driven shaft of the transmission. Drive ratio change command programs based on the behavior of a very good driver manually controlling a comparable transmission, are stored in the control unit to assign varying numbers of the available gear ratios to different combinations of sensed conditions under which automatic drive ratio change is effected. |
