  • Vehicle drive force distributing apparatus
    Patent number: 8500596
    Abstract: A vehicle drive force distributing apparatus includes an irreversible transmission mechanism, an operating state determining component and a command value resolution switching component. The irreversible transmission mechanism prevents a radially oriented pressing force, generated between first and second rollers based on an inter-roller radial pressing force command value, from decreasing during a period while command value is constant to maintain the radially oriented pressing force at a prescribed value without operating an inter-roller radial pressing force generating source. The operating state determining component determines whether first or second vehicle operating states exists during which a first or a lower second precision level of drive force distribution control, respectively, is to occur between main and subordinate drive wheels.
