摘要： A steady state transmission ratio Base i is computed from a vehicle speed VPS and a throttle opening TVO (S1). An output shaft revolution speed No of the transmission and a current transmission ratio i are detected (S2, S3). A coefficient TTINR is computed from a difference or a ratio or the like between the steady state transmission ratio Base i and the current transmission ratio i (S4). Then, from the current transmission ratio i, the output shaft revolution speed No and the coefficient TTINR, a shift speed SV=TTINR/(IE.times.i.times.No) is computed (S5). Then a shift control is performed in accordance with the shift speed SV so as to approach to the steady state transmission ratio Base i (S6.about.S9). Thus, the shift speed during shifting in a continuously variable transmission is controlled in consideration of inertia torque.

摘要： In order to optimize the speed change control of a continuously variable transmission, a necessary minimum primary pressure (Ppmin) for achieving speed change ratio control, a necessary minimum line pressure (Plmin) for the non occurrence of slippage between a secondary pulley 3 and a belt 4, and a required speed change ratio line pressure (Plratio) which can realize a target speed change ratio without slippage on the primary pulley 2 side are computed. The highest of these is then selected, and a final output line pressure (Plprs) then obtained based on the selected line pressure. By using this line pressure (Plprs) to control a secondary pulley actuator 3a, slipping of the belt 4 can be prevented and a target speed change ratio achieved, with an extremely simple construction compared to that of conventional arrangements.

摘要： The up-shift is discriminated to be in any one of a first up-shift mode in which the throttle opening degree remains nearly constant, a second up-shift mode accompanying the operation for nearly fully closing the throttle or a third up-shift mode accompanying the operation for closing the throttle to a half opened state. On the other hand, the down-shift is discriminated to be either in a first down-shift mode which accompanies the operation for opening the throttle or in a second down-shift mode accompanying the decrease in the vehicle speed. The rate of changing the speed is set for each of the speed change modes, and the speed change ratio of the continuously variable transmission is so controlled that the actual speed change ratio is gradually brought to the basic speed change ratio based upon said rate of changing the speed.

摘要： A basic speed change ratio is set on the basis of vehicle speed and throttle valve opening, and a control target speed change ratio is made to gradually approach the basic speed change ratio in accordance with a speed change speed. Feedback control is then carried out so that the actual speed change ratio coincides with the control target speed change ratio. When there is an up-shift requirement with a rate of change in throttle valve opening equal to or less than a predetermined value, and a rate of change in the basic speed change ratio, which is set on the basis of operating conditions, equal to or less than a predetermined value, the speed change speed is faster than at the time of an up-shift requirement with throttle valve closure.

摘要： The speed change ratio of a continuously variable transmission is controlled so that the actual speed change ratio approaches the basic speed change ratio at a predetermined rate of changing the speed by setting the basic speed change ratio based upon the opening degree of the accelerator and the vehicle speed. Here, when a change in the basic speed change ratio accompanying the accelerator operation is against the direction in which the actual speed change ratio approaches the basic speed change ratio, the speed is forcibly and temporarily changed to follow the change in the basic speed change ratio.

摘要： An air/fuel ratio control system derives a air/fuel ratio dependent correction value for correcting a basic fuel delivery amount as a proportional-integral control value composed of a proportional component and an integral component. The proportional component is derived on the basis of an air/fuel ratio indicative signal which varies the signal level when the air/fuel ratio varies across a predetermined stoichiometric value. The integral component is derived on the basis of a basic fuel delivery amount which is derived on the basis of engine speed and an engine load.
