AUTOMATIC TRANSMISSION DEVICE AND CONTROL METHOD FOR AUTOMATIC TRANSMISSION DEVICE

摘要

Provided is an automatic transmission device comprising an oil temperature detection unit that detects the temperature of hydraulic oil, and a controller that controls the gear ratio on the basis of the oil temperature acquired from the oil temperature detection unit. If the oil temperature cannot be acquired from the oil temperature detection unit, the controller outputs a command to restrict output from a drive power source, and if the oil temperature can once again be acquired from the oil temperature detection unit, the controller gradually cancels the command to restrict output from the drive power source.
