Abstract
In a vehicle with an automatically controlled clutch in which ON-OFF of the friction clutch is automatically controlled by a controller, clutch control during coasting (with the accelerator depression amount being 0%) is conducted according to a clutch ON-OFF map for coasting provided in the controller. Two different clutch ON-OFF maps for coasting are provided; one having a smaller hysteresis width, and the other having a larger hysteresis width. Clutch control during coasting is conducted by applying the map with a smaller hysteresis width when the brake pedal is stepped on or applying the map with a larger hysteresis width when the brake pedal is not stepped on. Thus, clutch ON-OFF hunting can be avoided, and smooth stopping can be conducted.
