Japanese Patent JP4196962
Kind Code:
B2
Abstract:

To suppress the generation of shock in a vehicle when changing a distribution ratio of torque to be outputted to front wheels.

Engine 22 and motors MG1, MG2 and MG3 are controlled so that a requested distribution ratio requested as the ratio of torque to be shared on rear wheels 64a and 64b sides in relation to requested torque may be gently changed by performing a moderating control for the requested distribution ratio. When a state for outputting each negative torque to the front wheels 62a and 62b sides and rear wheels 64a and 64b sides is changed to a state for outputting positive torque to only front wheels 62a and 62b sides by regenerative controls of the motors MG2 and MG3 according to a change from negative to positive of a code of the requested torque, the engine 22 and the motors MG1, MG2 and MG3 are controlled so that torque to be outputted to the rear wheels 64a and 64b sides may be made a value 0 and torque to be outputted to the front wheels 62a and 62b sides may be gradually increased toward the requested torque.
