Abstract
A drive shaft protection apparatus may include a Revolutions Per Minute RPM) detection device configured to detect an RPM of an engine and of a turbine, a gear-shifting detection device configured to detect a lever position of a transmission, a steering-angle detection device configured to detect a steering angle, an accelerator pedal position detection device configured to detect a displacement of an accelerator pedal, an engine-torque detection device configured to detect an engine torque of a vehicle, a loss-torque detection device configured to detect loss torque of the vehicle, and a controller configured to change a limit torque based on a bending angle of a drive shaft upon receiving the steering angle, and variably perform engine torque reduction control in a manner that torque applied to the drive shaft does not exceed the limit torque in response to output signals of the respective detection device.
