Abstract

PURPOSE: To restrain sudden change of speed of engine rotation and alleviate an impact at speed change by controlling acceleration or deceleration of engine rotation at change of speed change stage of a speed change gear so that controlled speed may correspond with estimated speed of rotation after its change.
CONSTITUTION: A speed change gear controlling device 20 determines shift up or shift down of a speed change stage by each output signal Pn, es of a throttle opening sensor 18 supported by output shaft rotation speed sensor 17, accelerator pedal 7 of a torque converter 2, and sends out speed stage controlling signals SaWSd, engine accelerating signal eu and decelerating signal ed. In this case, the controlling device 20 are provided with a counter 21, separators 22, 23, up down counter 24 and timers 26, 27 and the like and establishes time required for bringing the controlled speed into approximate correspondence with an estimated speed of rotation of the torque converter 2 output shaft after speed change. Further, the controlling device 20 is made so as to drive a thrttle actuator 10 during the time for the abovementioned establishment at speed change.
