Abstract

PURPOSE: To perform operation in a state as required from the operator, by applying mutual advantage between automatic control and manual operations of a device and constituting the device selectively changeable through optional switching from manual to automatic operations.
CONSTITUTION: A switch A is selected to an automatic side, then a transmission device 1 is automatically controlled by an automatic controller 6. The switch A is selected to a manual side and a conversion position of the automatic controller 6 is placed to the first position, then the transmission device 1 is manually controlled by a manual controller 12. At this time, though a speed change signal is not outputted from the automatic controller 6 at the first position, a lock up valve 5 in a torque converter and a preventive device 7 of engine overrun are automatically controlled by a detecting value of a speed sensor 4 through the automatic controller 6.
