Claims

[Claims for Utility Model Registration] A power split device that distributes and transmits engine driving force to the front and rear or left and right drive wheels, and a drive system that is installed between the input and output parts of the power split device and that generates transmitted torque by external control force. A vehicle drive system clutch control device comprising a clutch means and a clutch control means for outputting a control signal for increasing/decreasing the clutch engagement force based on an input signal from a detection means, wherein the detection means includes a front and rear wheel or a left and right wheel. The clutch control means includes a rotational speed difference detection means, an accelerator opening detection means, and a high-speed large-radius turning detection means, and the clutch control means adjusts the high-speed large-radius turning degree to a reference clutch engagement force that increases as the rotational speed difference increases. A clutch control device for a drive system for a vehicle, characterized in that it is a means for controlling a clutch engagement force to be added to a corrected clutch engagement force obtained by a characteristic in which the gain of the clutch engagement force with respect to the accelerator opening is decreased as the clutch engagement force increases.
