なわせることができないなどの問題点があった。As described above, the conventional engine test control device lt performs control for deviations using constant control constants, regardless of the operating state of the engine. However, do actual engines have nonlinear characteristics? For example, as shown in the characteristic diagram of FIG. 2, it has a throttle opening-engine output torque characteristic with the engine speed as a parameter. As shown in this figure, the engine output torque varies depending on the throttle opening degree and engine speed, so conventional control devices that perform control using a fixed control constant cannot perform full follow-up control with a good tN degree. There was a problem.

In other words, in the case of the engine characteristics shown in Figure 2, the correction value of the control constant is set to a constant value in a region where the rate of change of engine output torque is constant relative to the rate of change of throttle opening; In a region where the rate of change is small, the correction value of the control constant is increased. FIG. 2 shows an example of the characteristics of the control correction coefficient 7 when the throttle opening is used as a parameter. The control constant corrector 8 changes the manipulated variable of the throttle opening according to the value of the control correction coefficient 7, and controls the engine.
