โœฆ Synopsis

If an engine with an electric throttle valve control and CVT is "tted to the powertrain, fuel consumption becomes economical while the throttle valve angle and the gear ratio of CVT are controlled simultaneously. If the engine is operated with a lean air-fuel ratio (A/F), it is also e!ective for fuel economy. Therefore, combining A/F control with the simultaneous control of the throttle valve angle and the gear ratio becomes a more important method for controlling the powertrain of a car. Though these input-output relations were complicated, an adequate and convenient control method was required for the synthetic powertrain control. From such a point of view, Engine-CVT-A/F consolidated control using decoupling control theory was investigated.

For the drivetrain control, it has become important for fuel economy or AHS to control the throttle valve of the engine and the gear ratio of CVT simultaneously by DBW when the automobile is equipped with CVT. In this paper, LQI control theory was applied to control the drivertrain as a 2-I/O system
