When the driver requests to start the vehicle with the brake OFF and depressing on the accelerator pedal APO, and thereby a target drive torque exceeds a gradient load, prior to exceeding, in order to avoid excess current being supplied to the motor, the upper limit of motor speed tNm, which is the input speed of a second clutch is set to a value less than a slip detectable limit value ωLLIM at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed tNm) is set to a value equal to or greater than ωLLIM so that the required driving force can be achieved by the gradient load corresponding driving force control. |
