摘要： A vehicle engine throttle valve control apparatus whereby the actuation position of an accelerator pedal, the degree of opening of the throttle valve, and the position of the vehicle gear shift are detected. One of a plurality of different throttle valve target opening degree characteristics is then selected which corresponds to the current gear shift position, and the selected characteristic is used to set a target degree of opening for the throttle valve in accordance with the accelerator pedal position. The throttle valve is driven so as to make the actual degree of throttle opening become equal to the target value. Appropriate throttle control is thereby automatically performed each time a gear shift operation is executed, without intervention by the vehicle driver.

摘要： A hydraulic continuously variable speed transmission with a direct clutch valve comprises a hydraulic pump, a hydraulic motor, a hydraulic closed circuit for hydraulically connecting the both, a direct clutch valve placed in the closed circuit, a speed reduction ratio control actuator, and a direct clutch valve controlling device for controlling operations of said direct clutch valve to block the closed circuit when the speed reduction ratio becomes substantially "1". The direct clutch valve controlling device maintains a direct connecting state when an actual engine speed is higher than a direct clutch disconnecting reference engine speed at the speed reduction ratio of approximately "1". Then, the direct clutch valve control device releases the blocking of the closed circuit by the direct valve when a drop of the actual engine speed from the direct clutch disconnecting reference engine speed exceeds a predetermined amount corresponding to the vehicle speed.

摘要： A throttle valve control apparatus for a vehicle engine, whereby a reference degree of opening of the throttle valve is derived based on the accelerator pedal actuation position and is then corrected in accordance with vehicle operating conditions to obtain a target degree of opening of the throttle valve. An upper limit opening degree and a lower limit opening degree of the throttle valve are also derived, and if the target opening degree, which is obtained on the basis of the vehicle operating conditions, is found to be greater than the upper limit opening degree, then the upper limit opening degree is used as the target opening degree. Similarly, if the target opening degree, which is determined from the vehicle operating conditions, is less than the lower limit opening degree, then the lower limit opening degree is used as the target opening degree. The throttle valve is driven at a controlled drive speed so as to reduce any deviation between the actual degree of opening and the target degree of opening of the throttle valve.

摘要： A continuously variable transmission on a motor vehicle is controlled by establishing a target terminal acceleration GO to be reached according to an indication of the driver's intention for acceleration or deceleration, such as the amount of depression of the accelerator pedal, and also to an indication of the speed of the motor vehicle. A present calculative acceleration G.sub.CAL is calculated on the basis of a marginal power Pa of the engine which drives the continuously variable transmission. A target present acceleration Gon required at the present time to vary the present acceleration up to the target terminal acceleration Go to be reached along a desired characteristic curve is established according to the difference .DELTA.G (=Go-G.sub.CAL) between the target terminal acceleration Go to be reached and the calculative acceleration G.sub.CAL. Then, the throttle valve of the engine on the motor vehicle and the continuously variable transmission are controlled so that the target terminal acceleration Gon will be reached.

摘要： A time-dependent engine output power characteristic curve for an engine output power to vary therealong to a target value which corresponds to an indication of intention of the driver for acceleration or deceleration (e.g., the amount of depression of the accelerator pedal) is established based on the difference between a target engine output power and an actual engine output power. Then, a target rate of change of the rotational speed of the engine and a target rate of change of an indication of an engine load are established so that the actual engine output power varies along the engine output power characteristic curve, and the throttle valve and the continuously variable transmission are controlled using the target rates thus established.
