ABSTRACT:
In a method for automatically controlling a vehicle transmission system having a gear-type transmission and a clutch, in the case where the system is controlled in a control mode wherein the clutch is disengaged so as to prevent idle running of the vehicle when the amount of operation of the acceleration pedal becomes less than a prescribed level, when the clutch is engaged in response to an increase in the running speed of the vehicle, the control mode is changed to another control mode in which the engaged state of the clutch is maintained even if the amount of operation of the accelerator pedal becomes zero. Thus, in case of, for example, a vehicle drive-off mode for snow-covered road condition, it becomes possible to realize smooth vehicle running at low speed without need to depress the accelerator pedal.
