Abstract
In control apparatus and method for taking failure countermeasure for a hybrid vehicular drive system, on a lever diagram of a planetary gear mechanism, a revolution speed order is a first motor/generator, an engine, the output member, and a second motor/generator, high-brake and low-brake are arranged at one and the other ends of the lever diagram, respectively, with the output member as an intermediate position on the lever diagram, an output abnormality of each of the engine, the first motor/generator, and the second motor/generator which are drive sources is detected, and, with one of the first and second clutching sections clutched, a vehicular run using at least one of the drive sources whose output is detected to be normal is enabled when the drive source output abnormality detecting section detects that the output abnormalities in any one or two of the drive sources occur.
