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

摘要

Three determination elements Jc[1] to Jc[3] are set among three clutches and one brake (S100); predetermined-time assumed currents Iref[1] to Iref[3] are set on the basis of the combination of the set three determination elements Jc[1] to Jc[3] (S110 to S170); and defining respective currents to be applied to solenoids of three linear solenoid valves corresponding to the three determination elements Jc[1] to Jc[3] as determination currents Ij[1] to Ij[3], it is determined whether or not braking torque is generated on an output shaft of an automatic transmission by comparing the determination currents Ij[1] to Ij[3] and the corresponding predetermined-time assumed currents Iref[1] to Iref[3] (S180 to S250).
