<P>PROBLEM TO BE SOLVED: To suppress shift shock when a shift stage is shifted when braking force is outputted to a driving shaft by an electric motor through a transmission and to suppress heat generation on a clutch and a brake required for shifting of the shift stage. <P>SOLUTION: When requirement for shifting of the transmission 60 is performed when the braking force is outputted from a motor MG2, braking torque from the motor MG2 is replaced by brakes 89a, 89b of driving wheels 39a, 39b, thereby, it is made to the state that torque is not outputted from the motor MG2. Thereafter, the transmission 60 is shifted and after shifting, braking torque replaced by the brakes 89a, 89b is replaced by the braking torque from the motor MG2. Thereby, shock generated at shifting can be suppressed and heat generation of the clutch and the brake required for shifting can be suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
