。[Claims for Utility Model Registration] 1. An automatic transmission interposed in a drive system between an engine and wheels, a 2-4 switching mechanism for switching between two-wheel drive and four-wheel drive, and an automatic transmission within the automatic transmission. an oil temperature detection means for detecting the lubricating oil temperature; a determination means for outputting a signal when the lubricating oil temperature detected by the oil temperature detection means exceeds a set value; and an output signal from the determination means. 1. A control device for a four-wheel drive vehicle equipped with an automatic transmission, comprising: control means for forcibly switching the 2-4 switching mechanism to the two-wheel drive side based on the transmission. 2. An automatic transmission interposed in the drive system between the engine and the wheels, a locking means for locking a center differential interposed between the front wheels and the rear wheels, and lubricating oil in the automatic transmission. an oil temperature detection means for detecting temperature; a determination means for outputting a signal when the lubricating oil temperature detected by the oil temperature detection means exceeds a set value; 1. A control device for a four-wheel drive vehicle equipped with an automatic transmission, comprising: control means that acts to release the lock by the locking means.
