Abstract

In order to improve the accuracy of magnetic parking location detection, the microcontroller needs to use transcendental function to exclude the parking interference of adjacent parking process. Because the microcontroller does not contain hardware multipliers, the function approximation algorithm is introduced. In this paper, the CORDIC algorithm and digit-by-digit algorithm are used to estimate the square root and arccosine function in the process of magnetic data processing. Experiments show that after adding the algorithm, the running time of the microcontroller is much less than the sampling interval of the sensor. The experimental results prove that the algorithm can exclude the interference of adjacent parking process in real time.
