Title: Semiconductor device, angle value correction circuit and method therefor
Inventor: SHIBUYA YOSHITAKA
IPC: B60L15/20
Filed: 2018-11-06
Abstract: According to the present invention, it is possible to perform correction of a rotation angle value without an increase in a circuit size. A rotation period measurement unit (151) measures a rotation period of a rotary shaft of which a rotation angle is detected, by using a resolver that outputs a signal corresponding to a rotation angle of the rotary shaft. A rotation speed calculation unit (152) calculates a rotation speed of the rotary shaft based on the rotation period. An acceleration calculation unit (153) calculates the rate of change in the rotation speed per interval when a predetermined rotation angle of the rotary shaft is divided into 2^(n+1) intervals, wherein n is an integer greater than or equal to one. An estimated angle calculation unit (154) calculates a rotation angle estimation value, assuming that the rotary shaft performs a uniform acceleration motion, based on the rotation speed and the rate of change in the rotation speed. A correction value calculation unit (155) calculates a correction value of the rotation angle value converted from an output signal of the resolver. A correction value application unit (156) generates a corrected angle value by applying the correction value to the rotation angle value.
