Abstract: PURPOSE: A belt slip sensing method of a rack type electric power steering system is provided to improve driving stability by recognizing generation of a belt slip in the rack type electric power steering system. CONSTITUTION: A steering angle signal is transmitted from a steering angle sensor of a rack type electric power steering system. A normal motor rotation angle is calculated by using the transmitted steering angle signal and data of the electric power steering system. A current motor rotation angle signal is transmitted from a motor angle sensor of the rack type electric power steering system. The calculated normal motor rotation angle and the current motor rotation angle are compared(S101). When a difference is in the calculated normal motor rotation angle and the current motor rotation angle, a motor is stopped, and a warning lamp inside a vehicle is turned off(S103). [Reference numerals] (AA) Start a slip sensing logic; (BB) Steering angle; (CC) Motor rotating angle; (S101) Difference between a steering angle based motor rpm and an actual motor rpm
