Abstract:
A control apparatus of an automatic transmission including a plurality of planetary gear mechanisms and engaging mechanisms configured to establish a gear range by switching inputs/outputs of the plurality of planetary gear mechanisms, comprises an oil pressure supply device which supplies an oil pressure to operate the 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 gear range 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.

Claim (Index 10):
A control method of an automatic transmission including:\n a plurality of planetary gear mechanisms and engaging mechanisms configured to establish a gear range by switching inputs/outputs of the plurality of planetary gear mechanisms; an oil pressure supply device configured to supplying an oil pressure to operate the engaging mechanisms between an engaging state and a release state in which the engaging state is canceled; and a gear change controller configured to control 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 method comprising: calculating a temperature of each of the engaging mechanisms in the gear range after a gear change; calculating a cooling rate of each of the engaging mechanisms in the gear range after the gear change based on the temperature and the operation state of each of the engaging mechanisms; calculating an allowable temperature of each of the engaging mechanisms in the gear range after the gear change based on the cooling rate of each of the engaging mechanisms; and executing gear change control of controlling the gear change to the gear range 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 the allowable temperature.
