Title:
シフトレンジ制御装置
Document Type and Number:
Japanese Patent JP7135757
Kind Code:
B2
Abstract:
A shift range control device includes an encoder count unit, an energization control unit, a learning unit, an energization phase count unit, and an abnormality determination unit. The encoder count unit calculates an encoder count value based on an encoder signal. The energization control unit controls energization to the motor. The learning unit learns a wall position that is the encoder count value when an engaging member abuts on the wall portion. The energization phase count unit calculates an energization phase count value that is counted according to switching of the energization phase. The abnormality determination unit determines an abnormality of the encoder based on the energization phase count value and the encoder count value before and after learning the wall position.
