Abstract:
1. A control apparatus for a shift-position changing mechanism that changes shift positions of a transmission using a rotational force of an actuator based on a signal corresponding to a state of an operation member which is provided with a magnetic member, comprising: a detection unit that is provided on a path along which the operation member is moved, and that detects a change in a magnetic field which is caused due to a change in a position of the operation member; and a determination unit that determines the shift position corresponding to a position, to which the operation member has been operated, based on the detected change in the magnetic field and predetermined multiple modes of changes in the magnetic field, which correspond to the respective shift positions, wherein the predetermined modes of changes in the magnetic field are set such that, when the detected change in the magnetic field is influenced by a change in the magnetic field, which is caused due to a factor that differs from the change in the position of the operation member, a likelihood that the determination unit determines that the running shift position, at which a vehicle is able to run, is selected is reduced.
