PURPOSE: A coasting control method is provided to prevent the loss of driving feeling and durability due to the frequent operation of a clutch. CONSTITUTION: A controlling method of an AMT hybrid vehicle variably controls a regenerative braking amount according to a manipulated variable of an accelerator pedal within a specific control range and reduces the regenerative braking amount as the manipulated variable of an accelerator pedal increases. When the manipulated variable of an accelerator pedal is within the specific range, a conversion index for decelerating with regard to a current manipulated variable of an accelerator pedal is obtained, the conversion index for decelerating is calculated, and a regenerative braking is conducted to satisfy the required torque amount of conversion decelerating. [Reference numerals] (AA) Starting the driving of a driver's vehicle; (BB) Vehicle speed > 0; (CC) Acceleration pedal manipulated value > 10; (DD) Driving demand maximum torque X (acceleration pedal manipulated value(%) /100); (EE) Distributing engine/motor driving torque; (FF) Accelerating the vehicle; (GG) Conversion deceleration demand torque > motor maximum regenerative torque; (HH) Regenerative braking with only motor; (II) Motor regenerative braking + engine friction; (JJ) Decelerating the vehicle; (S20) Deceleration demand conversion index = F(acceleration penal manipulated value); (S30) Conversion deceleration demand torque = deceleration demand torque X(deceleration demand conversion index(%) /100)
