Patent ID: 6878085

Claim:
A power distribution control apparatus of a vehicle for distributing an input torque transmitted through an input shaft into a first output torque and a second output torque through a first output shaft and a second output shaft, respectively by means of a differential mechanism and for controlling a distribution ratio of said first output torque to said second output torque by controlling an engagement force of a clutch mechanism provided between said first output shaft and said second output shaft, comprising: target differential rotation speed establishing means for selectively establishing a target differential rotation speed between said first and second output shafts; actual differential rotation speed detecting means for detecting an actual differential rotation speed between said first and second output shafts; and differential limiting torque establishing means for selectively establishing a differential limiting torque of said clutch at least based on said target differential rotation speed, said actual differential rotation speed and a deviation between said target differential rotation speed and said actual differential rotation speed.
