摘要： In a transmission control device for controlling a transmission, a controller determines failure of a specific section. The controller variably controls line command pressure and secondary command pressure, and in a case where the failure is determined, fixes the line command pressure to a line pressure set value and the secondary command pressure to a secondary pressure set value. In a case where the failure is determined, the controller further starts a change in the secondary command pressure after start of a change in the line command pressure, and controls the secondary command pressure in such a manner that the secondary command pressure takes a first predetermined time to have the secondary pressure set value.

摘要： An automatic transmission includes an oil temperature detecting unit configured to detect an oil temperature of the hydraulic oil, and a controller configured to perform the control of the speed ratio on a basis of the oil temperature obtained from the oil temperature detecting unit. The controller is configured such that if the controller has failed to obtain the oil temperature from the oil temperature detecting unit, the controller outputs a command to restrict an output from the driving force source, and such that if the controller has obtained the oil temperature from the oil temperature detecting unit again, the controller gradually cancels the command to restrict the output from the driving force source.

摘要： There are provided a continuously variable transmission (CVT) in which a belt (7) is wound around a primary pulley (5) and a secondary pulley (6) to transmit power; a primary pulley rotational speed sensor (13) for detecting a rotational speed of the primary pulley (5); a vehicle stopped state determination means for determining whether a vehicle is in a stopped state; a belt slippage detection means for detecting belt slippage on the basis of a signal of the primary pulley rotational speed sensor (13); and a prohibition means for prohibiting detection of the belt slippage by the belt slippage detection means when a parking range or a neutral range is selected by a shift lever operation by a driver. In the vehicle stopped state during selection of the parking range or the neutral range, the rotational speed of the primary pulley (5) is not basically output, and the belt slippage does not occur. Thus, erroneous detection of the belt slippage can be avoided by prohibiting the detection of the belt slippage in this case.
