  • Patent number: 11614163
    Abstract: A motor control method for a shift-by-wire system recognizes a current position of a switched reluctance (SR) motor at a point in time when a shifting request is input as a start position and determines whether the current position of the SR motor is the same as a target position, applies a current for rotating the SR motor toward the target position when the current position and the target position are not the same, counts time until a point in time when an actual motion of the SR motor is sensed, performs advanced-angle control of increasing a rotation speed of the SR motor when the counted time exceeds the time reference value, and measures a current applied to the SR motor and increases the advanced-angle control or performs retarded-angle control of decreasing the rotation speed of the SR motor, depending on the measured current value.
