PPROBLEM TO BE SOLVED: To suppress shift shock and increase in energy loss in shifting a transmission. PSOLUTION: When a shifting request of a transmission 60 is given while a braking force is being outputted from a motor MG2, an output of the motor MG2 is limited irrespective of a charging request of a battery 50, so that the driving torque is kept not to be transmitted to a driving axis from an engine 22. After a braking torque from the motor MG2 is replaced with brakes 89a, 89b, the transmission 60 is shifted and the braking torque by the brakes 89a, 89b is replaced with the braking torque from the motor MG2, so that the output limitation of the engine 22 is canceled. Thus, the shift shock can be suppressed by which the transmission 60 is shifted with the braking torque from the motor MG2 kept not to be outputted by the brakes 89a, 89b, and the increase in the energy loss can be restrained by which the power from the engine 22 is not wasted by the brakes 89a, 89b when replacing the braking torque of the motor MG 2 with the brakes 89a, 89b.
