摘要： The throttle valve position is sensed and the effective cross sectional area of the induction passage determined via table look up. The value thus derived is divided by the engine speed. A basic air induction quantity is then determined via table look up and subsequently modified using a correction coefficient to allow for the effect of engine speed on the amount of air inducted into each cylinder. The effect of injector position (viz., MPI/SPI) is taken into consideration and values suited for both generated in given embodiments. In the event that the maximum induction vacuum is limited by a BCD valve or the like, an embodiment anticipates the change in induction characteristics based on the engine speed.

摘要： The throttle valve position of an engine is sensed and the effective cross sectional area of the induction passage is determined via table look-up. The table is recorded in terms of three parameters. The value thus derived is divided by the engine speed of alternatively a product of the engine speed and the engine displacement. A basic air induction quantity is then determined via table look-up and is subsequently modified using a correction coefficient to allow for the effect of engine speed on the same. The effect of injector position (viz., multi-point injection/single point injection) and/or the provision of a swirl control valve can be additionally taken into consideration via the use of suitable algorithms or additional two and three parameter system tables. If an idle control by-pass passage is provided, the effect of the opening degree is considered when determining the effective cross-section of the induction passage.

摘要： The transmission controller changes the gear position of the subtransmission mechanism and varies the speed ratio of the variator in an opposite direction to a speed ratio variation direction of the subtransmission mechanism when the actual through speed ratio passes a predetermined mode switch line. When the improvement in the shift response of the continuously variable transmission is determined to be required and the actual through speed ratio passes the mode switch line from a Low side to the High side, the transmission controller increases a shift speed of the subtransmission mechanism compared with a normal coordinated shift.
