Claims

[Scope of utility model registration request]

A clutch disengagement means for disengaging and disengaging a mechanical clutch, a gear shift means for shifting gears of a transmission, an engine rotation control means for controlling engine rotation, and a shift determination means for discriminating that a shift range has been entered from an engine operating state. and means for detecting a shift position of a transmission in an automatic transmission system for a vehicle, comprising: a shift operation control means for lowering and increasing the engine rotation based on the determination signal, engaging and disengaging the clutch, and shifting the gear to a predetermined gear position. a failure determining means for determining a failure of the shift position detecting means according to a preset determination table based on this output signal; and a failure determining means for determining a failure of the shift position detecting means in accordance with a preset determination table based on the output signal, and a failure determination means for determining a failure of the shift position detecting means based on a preset time chart for driving the gear shift means when a failure occurs in the shift position detecting means. What is claimed is: 1. An automatic transmission device for a vehicle, characterized in that it is provided with backup means for controlling the transmission.
