METHOD FOR MEASURING STEERING ANGLE BY USING YAW RATE GYROSCOPE SENSOR

摘要

PURPOSE: A steering angle measuring method is provided to precisely measure a steering angle of a steering wheel by installing a yaw rate gyroscope sensor on the steering wheel or a steering shaft. CONSTITUTION: A yaw rate gyroscope sensor(40) is used for measure a steering angle of a steering wheel(10). The yaw rate gyroscope sensor(40) has a compact size and superior endurance against external impact. The yaw means a movement in left and right directions. The yaw rate gyroscope sensor(40) is installed on the steering wheel(10) or on a steering shaft(30). When a driver operates the steering wheel(10) in left and right directions, the yaw rate gyroscope sensor(40) detects the movement of the steering wheel(10), thereby calculating an angular velocity. When a vehicle straightly runs, a value of the yaw rate gyroscope sensor(40) is zero.
