Torque controlling apparatus and method for hybrid vehicle
First Claim
1. A torque controlling apparatus for a hybrid vehicle, comprising:
- a clutch rate adjustable clutch, an output axle of the clutch being connected to driven wheels;
an engine;
a generator, both of the engine and the generator being connected to an input axle of the clutch;
a motor connected to the output axle of the clutch; and
a controller to control a vehicular propelling torque transmitted to the driven wheels under a predetermined torque distribution condition, the controller including;
a power supplying section that makes the motor perform a power running by supplying a generated electric power obtained as a result of a drive of the generator by the engine to the motor; and
a torque distribution section that distributes an engine torque into a clutch transmission torque transmitted to the driven wheels via the clutch and a generation torque transmitted to the generator, the torque distribution section controlling the clutch rate of the clutch and the generation torque of the generator on the basis of at least a vehicular velocity.
