<P>PROBLEM TO BE SOLVED: To suppress a torque shock acting on a drive shaft by an accelerator operation to request acceleration when torque from the rotary shaft of a motor is not output to the drive shaft in the case of performing the down-shift of a shift means. <P>SOLUTION: When it is determined that the down-shift of a transmission 61 is operated, the rotary shaft of a motor 42 is set so as to be rotatable independently of a drive shaft for performing the down-shift of the transmission 61, and synchronous rotation processing to synchronize the number of rotation of the motor 42 with the necessary number of rotation after shift-down is performed (time t2 to t3). When an accelerating operation to request acceleration is performed during the synchronous rotation processing, an allowable changing amount as the allowable value of the changing amount of the power of an engine 32 is set to a second changing amount ΔP2 which is smaller than a value (first changing amount ΔP1) during no synchronous rotation processing so that the rapid change of the power of the engine 32 can be suppressed, Thus, even when the torque can not be output to the drive shaft by the motor 42, the torque shock which is generated in the drive shaft can be suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
