A method for controlling an auto cruise speed of a vehicle includes: determining a feedback torque for correcting a speed error between a target speed set by a driver of the vehicle and a current speed that is a feedback speed detected by a speed sensor of a vehicle; determining a drive resistance according to the target speed by inputting the target speed; determining a first feedforward torque according to the determined drive resistance; determining a second feedforward torque based on a vehicle inertia and a variation of the target speed by inputting the target speed; and outputting a command for generating a wheel required torque that is corrected by adding the first feedforward torque and the second feedforward torque to the feedback torque.
