<p>PROBLEM TO BE SOLVED: To realize an optimum speed gear changeover in an early stage by controlling measure to exert influence on a gearbox input moment for shift operation, namely, a device varying the geometrical characteristics of an exhaust duct of an internal combustion engine, a solenoid brake, a fuel injection quantity, throttle valve opening, ignition timing or the like. SOLUTION: When a gearbox controller 130 delivers a positive moment request to an engine controller 120, an injection valve 1014 is opened longer than in usual operation to raise the engine speed, and a lot of fuel is sprayed to a combustion chamber, while the valve opening of a throttle valve 1011 is opened. In addition, at need, a subassembly, for example, an air-conditioning compressor 107a and a current generator 107b are interrupted from a power transmission system. On the other hand, in an up-shift process having a negative moment request, the engine speed is lowered, and when the gearbox controller 130 has requested the aid of this up-shift, the ignition timing is adjusted in an earlier direction. A reduction in the engine speed is realized by reducing the fuel quantity and closing the throttle valve 1011.</p> |
