<P>PROBLEM TO BE SOLVED: To control a drive torque difference in switching EV traveling and HV traveling by compensating the errors of an actual value and a command value of the output torque by aging and machine difference of an engine and an electric motor respectively as the drive power source for traveling. <P>SOLUTION: The errors of the actual value and the command value of the output torque by the aging and the machine difference of the engine 14 and the electric motor MG respectively can be compensated since a clutch K0 for connecting and disconnecting the engine is connected in the state that the transmission in an automatic transmission 18 is intercepted, and the engine 14 is carried out rotation operation, and at that time, the estimation engine torque T<SB POS="POST">E</SB>es is corrected by the learning based on a positive and negative reverse value of the motor torque T<SB POS="POST">MG</SB>. In a word, since the engine torque T<SB POS="POST">E</SB>is detected by using the electric motor MG as the drive power source for traveling, the error of the actual value and the command value of the output torque by aging and machine difference of the engine 14 and the electric motor MG respectively are corrected in the mutual relation of the engine torque T<SB POS="POST">E</SB>and the motor torque T<SB POS="POST">MG</SB>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
