<P>PROBLEM TO BE SOLVED: To provide a control device of a hybrid four-wheel drive vehicle capable of enhancing the startability when a temporarily large motor driving force is required such as when the vehicle starts on a frozen road or a much snowy road of steep slope. <P>SOLUTION: The hybrid four-wheel drive vehicle comprises an engine 1 having an engine speed control means 11 capable of controlling the engine speed according to the driving request, a generator 3 to convert a part of the output of the engine into the electric power, a motor 4 to perform the power drive by directly receiving the supply from the generator, first driving wheels 20F in which the driving force of the engine is transmitted via a power transmission mechanism to permit the relative rotation between the input and the output, and second driving wheels 20R to be driven by the motor, and further comprises an engine speed correction means S14 to increase and correct the engine speed so as to reach the target engine speed while permitting the relative rotation between the engine and the first driving wheels if the requested engine speed is lower than the lower limit of the target engine speed corresponding to the requested torque of the motor when the vehicle starts in a four-wheel drive mode to generate the driving force in the first and second driving wheels. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
