Mode switch control apparatus and method for hybrid transmission

In mode switch control apparatus and method for a hybrid transmission, both of a torque transmission capacity of one of a predetermined clutch (Chi,Cin) and a predetermined brake (BLO,BLH) which is engaged when a mode switch is carried out and a torque change of one of motor/generators (MG1,MG2) along with a polarity reversal in the one of the motor/generators (MG1,MG2) when the polarity reversal is involved in the motor/generator (MG1,MG2) before and after the mode switch is carried out are mutually interlocked.
