Abstract
A shifting mechanism includes a limit switch that sends an open-close signal of the switch contacts SW, SW, SWand SWout to a control mechanism according to a 2H-4H-N-4L shifting sequence. The switch contacts SWand SWdetect the position of a slider 4H which is moved by a thrust actuator, during shifting in the range of 4H engagement to the range of N engagement. Therefore, if one of the switch contacts SWand SWis faulty, the other switch detects shifting between 4H and N. This prevents shifting into N over 4H, thereby preventing malfunction of the thrust actuator resulting from a faulty switch contact SWor SW. This also avoids potential difficulties in vehicle control due to shifting characteristics and permits the maintaining of controlled driving.
