发明名称 CONTROL DEVICE FOR AUTOMATIC TRANSMISSION
摘要 A control device for an automatic transmission configured with a command output portion that outputs a command that causes an electric pump to be driven so that oil pressure generated by the mechanical pump and the electric pump becomes greater than or equal to a needed oil pressure for a speed change mechanism when the oil pressure generated by the mechanical pump is smaller than the needed oil pressure. A determination portion determines whether or not a predetermined heat generation condition is met when the command is output by the command output portion. A shift control portion that, in a case where the determination portion has determined that the heat generation condition is met, performs a shift control of causing the speed ratio of the speed change mechanism to become higher than the speed ratio occurring when the determination portion determines that the heat generation condition is met.
