Disclosed are a power assisted towing mode control method and system for ecofriendly vehicles. The power assisted towing mode control method is executed to control a power assisted towing mode between a first vehicle as a towing vehicle and a second vehicle as a towed vehicle, and includes determining, by the first vehicle, whether or not an accelerator pedal amount exceeds a threshold value, calculating, by the first vehicle, driver request torque based on the accelerator pedal amount, calculating, by the first vehicle, motor allowable torque based on the driver request torque, receiving, by the second vehicle, the motor allowable torque and calculating motor dischargeable torque based on the motor allowable torque, and performing, by the second vehicle, motor torque output based on the motor dischargeable torque. 1. A method of towing an ecofriendly vehicle , wherein a first vehicle as a towing vehicle tows a second vehicle as a towed vehicle which is an ecofriendly vehicle and capable of communicating with the first vehicle , the method comprising:determining, by the first vehicle, whether or not an accelerator pedal amount exceeds a threshold amount value;calculating, by the first vehicle, driver request torque based on the accelerator pedal amount;calculating, by the first vehicle, motor allowable torque based on the driver request torque;receiving, by the second vehicle, the motor allowable torque and calculating motor dischargeable torque based on the motor allowable torque; andperforming, by the second vehicle, motor torque output based on the motor dischargeable torque.2. The method according to claim 1 , further comprising:determining, by the second vehicle, if discharge limit power of an energy storage system exceeds a threshold power value, when determined that the accelerator pedal amount exceeds the threshold amount value.3. The method according to claim 2 , wherein the calculating the motor dischargeable torque comprises:setting the motor ...
