摘要： This automatic clutch control device selects a normal mode when a road friction coefficient is not less than 0.3 at a disconnecting operation starting point (time t1), selects a little low-speed mode when it is not less than 0.1 but less than 0.3 and selects a low-speed mode when it is less than 0.1. Further, when a vehicle stabilizing control such as a traction control or the like is not executed at the time t1, this device selects the normal mode, while when a vehicle stabilizing control is executed at the time t1, it selects the low-speed mode. Moreover, this device selects a high-speed mode when the vehicle is in a sports running mode at the time t1, while selects the normal mode when the vehicle is not in the sports running mode. A connecting operation of a clutch is performed with a speed corresponding to the selected mode in an automatic clutch connecting/disconnecting control by a clutch connecting/disconnecting actuator upon executing a gear-shift control.

摘要： The automatic clutch control device according to the present invention controls, regardless of the gear-shift operation, the clutch 24 to be brought into a half-clutch state or to a perfect disconnecting state according to a running state of a vehicle from the following five viewpoints: deceleration slip amount of driving wheels RL and RR; a convergence time of a driving wheel speed to the driving wheel in a pressure-down mode during a vehicle stabilizing control (for example, ABS control); a continuation time of a judder vibration; whether the vehicle is in a spinning state or not; and whether there is a possibility that an engine stall occurs during a traction control. As a result, this device can attain at least one or more objects of the improvement in stability of the vehicle, improvement in precision of the vehicle stabilizing control, improvement of comfortableness of the occupant and prevention of the occurrence of the engine stall.
