A method for controlling a hybrid starter and generator (HSG) is applied to an eco-friendly vehicle. The method includes HSG torque-output limiting control, and in particular, the HSG torque-output limiting control is divided into an HSG regeneration mode and an HSG driving mode in which output limitation of the HSG 3 is performed after torque limitation of the HSG 3. Furthermore, the HSG regeneration mode includes: a former regenerative torque output control in which an engine RPM is converted by a controller 10 into regenerative torque output of the HSG 3 for about 1 second when an engine starts idling to charge a battery, and a latter regenerative torque output control in which the engine RPM is converted into the regenerative torque output of the HSG 3 after 1 second to about five seconds to continue to charge the battery 7, and an HSG driving mode.
