Switching position detecting apparatus for vehicle and shift control device for vehicle

A detection device includes a lever, a magnet is disposed in the selector lever, four or more sensors, which faces to the magnet positions are arranged, and an ECU. The ECU is adapted to determine (i) a switching position based on signals output from the four or more sensors when the magnet with respect to the four or more sensors, in response to an actuation of the selector lever is relatively moved ( ii) to determine the shift position based on signals which are output from three or more of four or more sensors that are determined to be normal when one of the four or more sensors is abnormal, and (iii) to determine the abnormality based thereon, whether or not to output the three or more sensors during the travel of the vehicle a signal to a switching position, which relates to a case of driving in the direction opposite to a direction of travel of the vehicle.
