CONTROL APPARATUS AND METHOD OF AUTOMATIC TRANSMISSION

The invention provides a control apparatus and a method of an automatic transmission. The automatic transmission includes a plurality of planetary gear mechanisms and engaging mechanisms configured toestablish a gear range by switching inputs/outputs of the plurality of planetary gear mechanisms. The control device comprises an oil pressure supply device which supplies an oil pressure to operatethe engaging mechanisms between an engaging state and a release state in which the engaging state is canceled; and a gear change controller which controls an operation state of each of the engaging mechanisms of the planetary gear mechanisms to establish one gear range of a plurality of gear ranges. The gear change controller executes gear change control of restricting the gear change to the gearrange in a case in which the temperature of each of the engaging mechanisms in the gear range after the gear change is predicted to be not less than an allowable temperature. 本发明提供种自动变速器的控制装置以及控制方法。自动变速器具备多个行星齿轮机构以及对多个行星齿轮机构的输入
