The manual transmission of this apparatus includes an input shaft Ai to which power is input from an internal combustion engine E/G through a clutch C/T and an output shaft Ao from which power is output to drive wheels. This transmission has a plurality of EV travel gear stages (EV, EV-R) (different from the neutral) in which no power transmission system is established between the input shaft Ai and the output shaft Ao, and a plurality of HV travel gear stages (2-nd to 5-th) in which a power transmission system is established between the input shaft Ai and the output shaft Ao. This transmission has a connection changeover mechanism M2 which establishes and breaks connection between the output shaft Am of the electric motor M/G and the output shaft Ao. When an EV travel gear stage is selected, a "connected state" is always realized. When an HV travel gear stage is selected, a "disconnected state" is realized in some cases. Thus, in a manual transmission for an HV-MT vehicle which has "HV travel gear stages" and "EV travel gear stages," occurrence of a situation in which the temperature of the electric motor becomes excessively high can be restrained. |
