Abstract: PURPOSE: A fail-safe mode driving method for a steering angle sensor is provided to improve the fuel efficiency of a vehicle by reducing the waste of battery in a fail-safe mode. CONSTITUTION: A fail-safe mode driving method for a steering angle sensor comprises the following steps: determining whether the speed of a vehicle is higher than 5km/h by receiving the speed value of the vehicle from a speed sensor by an MCU(Motor Control Unit); calculating the steering angle estimation of a front wheel by using an acceleration sensor and the relative position of the front wheel; calculating a steering angle speed using the estimation and subsequently determining the turning or returning operation of a steering wheel; and controlling a motor pump to control an output signal by stages for inputting to a motor by the size of the steering angle speed. [Reference numerals] (AA) Start; (S14) Output 80% of the maximum value; (S15) Calculate an estimated steering angle using an acceleration sensor; (S16) Determine whether to turn or return; (S17) Output 10% of the maximum value; (S18) Divide steering angle speed into stages; (S19) Generate an output signal according to stages
