Abstract: An ECU executes a program that includes the steps of performing neutral shift control, clutch release control, and engine torque control when a shift is required, the ste of moving a shift selector shaft in a selecting direction when a gear is disengaged and a shift position is neutral even if a drive torque TQ is greater than ? and a clutch stroke C is less than ?, the step of performing synchro control, the step of performing clutch engagement control, and the step of performing gear engagement control.

Abstract: An automatic speed-change control and an method speed-change control apparatus of an actuator which automatically drives a speed-change mechanism in a manual gear transmission of an automobile, includes an operating mechanism for controlling the operation of the actuators, a detecting mechanism for judging a speed-change timing and detecting the degree of accelerator depression, a calculating mechanism for calculating an operating factor corresponding to the degree of accelerator depression detected by the detecting mechanism to set a drive amount to the actuator so that the actuator operates by the calculated operate factor, and a command mechanism for supplying the drive amount to the actuator calculated by the calculating means and giving an operating command to the actuator.
