A method of controlling a hybrid vehicle in case of slip of a Mild Hybrid Starter Generator (MHSG) drive belt is disclosed. The method may include determining an amount of torque assistance or an amount of regenerative braking according to the MHSG while the vehicle travels; instructing the MHSG to output a desired amount of torque, based on the amount of torque assistance or the amount of regenerative braking; detecting an output torque from the MHSG to compare the output torque with the desired amount of torque; and determining that slip occurs in the MHSG drive belt when a difference between the actual torque and the desired amount of torque exceeds a preference value, and performing control for slip prevention.
