Patent ID: 7103462

Claim:
A control device of an automatic transmission, including an input shaft to which a rotational force is transmitted from a driving source, a transmission mechanism that varies rotation of the input shaft and transmits the rotation to an output shaft, and a plurality of friction engaging components mounted in a plurality of shift steps of the transmission mechanism, and selectively switching between engagement and disengagement of the friction engaging components to switch the shift step of the transmission mechanism by setting a target shift step according to a request to switch the shift step and by individually controlling hydraulic pressures applied to the plurality of friction engaging components, the control device comprising: multiple shift controlling means that switches a state of control of the hydraulic pressures applied to the respective friction engaging components when a request to switch a shift to a new third shift step is made during performing a shift from a first shift step to a second shift step to thereby perform a multiple shift, wherein the multiple shift controlling means changes a method of performing the shift to the third shift step according to an engagement pattern which represents a combination pattern of engagement and disengagement of the respective friction engaging components in a steady state of the third shift step.
