CONTROL DEVICE OF POWER TRANSMISSION MECHANISM FOR VEHICLE

Title:

CONTROL DEVICE OF POWER TRANSMISSION MECHANISM FOR VEHICLE

Document Type and Number:

Japanese Patent JP2004176729

Kind Code:

A

Abstract:

To suppress an increase in power loss in a power transmission route when wheels are connected to a power transmission mechanism.

In this control device of the power transmission for a vehicle, the power transmission mechanism is connected to the wheels, and when a variation in the rotation of the wheels occurs according to a road state, the torque capacity of the power transmission mechanism is controlled. The control device comprises a road state determination means (step S1 to step S5, step S7 to step S10, step S12) determining the continuity of a specified road state and a torque capacity control means (step S6, step S11, step S13) controlling the torque capacity of the power transmission mechanism based on the results of the determination of the road state determination means (step S1 to step S5, step S7 to step S10, step S12).
