Initial learning processing is performed to learn a phase deviation correction value for the power supply phase relative to a count value of a pulse signal of an encoder. As a restraint caused by a shape of a detent mechanism, the motor need be rotationally driven so that a detent lever does not move in a negative direction beyond a bottom position of a P-range in the initial driving operation. In a case of performing the initial learning processing in the P-range in consideration of this restraint, the initial learning processing is performed by setting a rotation direction of the motor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Range switchover apparatus","description":"When electric power supply is started, an initial driving operation is performed to switch over a power supply phase of a motor in open-loop control.
