Abstract: A pointer stability control method of automobile LCD instrument is designed to solve the problems of irregular jitter of virtual instrument panel pointer, large single rotation angle and poor visual effect caused by jitter and mutation of collected data signal. By setting the pointer target position value cyclically and applying different interpolation algorithms to the data change trend, the influence of data jitter mutation is weakened, and the damping effect is simulated to improve the overall visual effect of the instrument.
