1. A shift control apparatus comprising:

  • a shift intention detecting device that electrically detects a shift intention of a driver;

    a shift driving device that is electrically controlled based on the shift intention of the driver;

    a shift mechanism that is mechanically displaced into any one of a plurality of shift positions by the shift driving device;

    a first position information detecting device that detects, without contact, position information of the mechanical displacement of the shift mechanism;

    a shift position determining device that determines the shift position based on the position information;

    a second position information detecting device that detects the position information of the mechanical displacement of the shift mechanism in a different way than the first position information detecting device does;

    a malfunction determining device that determines whether the position information detected by the first position information detecting device is erroneous; and

    a switching device that switches from control based on the first position information detecting device to control based on the second position information detecting device when it has been determined that the position information detected by the first position information detecting device is erroneous.
