駆動力配分装置
Document Type and Number:
Japanese Patent JP5533344
Kind Code:
B2
Abstract:
A vehicle drive force distributing apparatus (1) includes an irreversible transmission mechanism (61), an operating state determining component and a command value resolution switching component. The irreversible transmission mechanism (61) prevents a radially oriented pressing force, generated between first and second rollers (31,32) 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 (58). 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. The command value resolution switching component provides the inter-roller radial pressing force command value at a constant value for a longer period during the second vehicle operating state.
