Abstract
This application discloses an adaptive control method, apparatus, and Hall device for a Hall effect device. The method includes: acquiring a sinusoidal signal and determining a maximum and minimum value in the sinusoidal signal; when the difference between the maximum and minimum values exceeds a first threshold, determining a first signal value and a second signal value based on the maximum and minimum values; wherein the first signal value is the signal value corresponding to the center position of the sinusoidal signal, and the second signal value is the signal value when the pulse signal corresponding to the sinusoidal signal changes; and performing signal conversion on the sinusoidal signal using the first signal value and the second signal value to obtain a target pulse signal. Applying the technical solution provided in this application achieves simpler and more convenient adaptive control of the Hall effect device, effectively reducing the R&D cost of the Hall effect device while ensuring the accuracy of the output results.
