Abstract
A method for preventing damage to a driving system in vehicles may include determining whether a 4-wheel drive vehicle turns based on a steering angle signal, determining, based on an accelerator opening rate signal of the vehicle, whether a maximum torque causing damage to front wheel driveshafts is produced, checking a bump stroke amount of the vehicle and determining whether the front wheel driveshafts are likely to be damaged by a maximum torque transferred to the front wheel driveshafts when the vehicle turns, and lowering, when the front wheel driveshafts are likely to be damaged, a maximum torque of a 4-wheel drive torque applied to the front wheel driveshafts.
