Abstract
In a gas turbine engine vehicle having a two-shaft type gas turbine engine including a gas generator constituted by a compressor and a compressor turbine arranged coaxially with the compressor, a combustion chamber, a variable nozzle, and a power turbine rotatable about a turbine shaft independently of a shaft of the compressor and the compressor turbine, a transmission speed ratio is shifted to a higher stage than the current transmission speed ratio when an engine acceleration requirement is greater than a predetermined value. As a result, a lowering of a vehicular acceleration characteristics due to a response lag in a variation of revolution speed at the compressor turbine can be prevented, and thus an enhanced acceleration and deceleration of the automotive vehicle is provided.
