TRANSMISSION CONTROL DEVICE, AND METHOD FOR DETERMINING GENERATION OF BRAKING TORQUE IN TRANSMISSION

It is determined whether or not braking torque is generated on an output shaft of an automatic transmission (S180 to S250) by setting three determination elements Jc[1] to Jc[3] among three clutches and one brake (S100), defining respective currents applied to solenoids of three linear solenoid valves corresponding to the set three determination elements Jc[1] to Jc[3] as determination currents Ij[1] to Ij[3], and comparing the determination currents Ij[1] to Ij[3] and corresponding predetermined-time assumed currents Iref[1] to Iref[3].
