<p>PURPOSE:To prevent the acceleration/deceleration characteristic from deteriorating so as to improve an acceleration/deceleration feeling of a vehicle by providing constitution such that a speed change shift of an automatic transmission is raised by one step from the present in the case of deciding an acceleration condition of an engine in acceleration of satisfying a predetermined condition. CONSTITUTION:Speed change control of a gas turbine vehicle which runs under speed control of an automatic transmission A/T is performed by speed changing an output of a two-shaft gas turbine engine provided with a gas generator GG comprising a compressor C and a compressor turbine CT coaxial with this compressor C, combustor CC, variable nozzle VN and a separate shaft output turbine PT. Whether an acceleration condition is acceleration or not of satisfying a predetermined condition is decided by detecting a steady condition and the acceleration condition of the engine, and a speed change shift of the automatic transmission A/T is shifted up by one step from the present in the case of deciding the acceleration of satisfying the predetermined condition. As a result, a rotational speed N3 of an output shaft through a reduction gear R/G of the output turbine PT is decreased, but here generated inertia force of an output turbine shaft system becomes acceleration energy, so that a delay of responsiveness in the initial acceleration of a vehicle is improved.</p> |
