ABSTRACT:
In a vehicle, it is determined whether a driver has requested increased driving force based on an accelerator opening degree. If the driver has requested increased driving force, a vehicle speed at the time of the request for increased driving force is derived. Three-dimensional map which corresponds to different vehicle speed and which shows a predetermined relationship of the accelerator opening degree (Acc), the vehicle speed and a required torque are then used to set the required torque. The maps are set such that the required torque increases with respect to the accelerator opening degree when the vehicle speed is low. Further, the maps are set such that when the vehicle speed is high, (i) even if the accelerator opening degree changes a little, the required driving force does not change a large amount, and (ii) the required driving force remains substantially constant when the vehicle speed is in a high speed region. By adopting this configuration, the driver's request is closely correlated with the vehicle speed at the time of the request for increased driving force, and thus the vehicle can be driven with a driving force that accords with the driver's request.
