In the calculating section 21, a required driving force (the torque value) Td is map searched from an accelerator opening APO and a vehicle speed VSP. In the multiplier 22, a required driving power Pd is calculated by multiplying the vehicle speed VSP by the required driving force Td. In the calculating section 23, based on a map related to the relationship between a combination of the required driving power Pd and the vehicle speed VSP, as well as a target motor rotational speed tNm that can achieve this combination with the optimal power consumption rate, a target motor rotational speed tNm that can achieve the combination with the optimal power consumption rate is detected from the Pd and the VSP. In the divider 24, the target motor torque tTm is calculated by dividing tNm by Pd and is used for the drive force control of the electric motor; in the divider 25, a target gear ratio i necessary to realize the target motor rotational speed tNm is calculated by dividing tNm by VSP and is used for the shift control of the automatic transmission (the rotational speed control of the electric motor). |
