摘要： A stimulus-based steering sensor device and a method for the same are disclosed. The sensor device comprises at least one driving wheel, a processor, two driven wheels, and two resolvers. The processor generates a stimulus signal and has a signal-angle lookup table. The driving wheel contacts two driven wheels. When following the rotation of a steering column, the driving wheel drives two driven wheels to rotate at different speeds. Two resolvers connect with the processor, respectively engage with two driven wheels, receive the stimulus signal, and respectively output two first sinusoidal signals to the processor according to the rotational speeds of two driven wheels. The processor analyzes two first sinusoidal signals to obtain two second sinusoidal signals having different periods, and uses the second sinusoidal signals and the signal-angle lookup table to obtain a first absolute angle value of the rotation of the steering wheel.
