Abstract: A method is disclosed for efficiently protecting dynamic compressors from surge under changing inlet conditions and in response to flow disturbances of varying size and speed. An antisurge control system based on this disclosed method will compute the relative proximity of the compressor operating point to its surge limit as a multi-variable parameter which is self-compensated for changes in gas composition, inlet temperature and pressure, compressor efficiency, guide-vane position, and rotational speed. A combination of adaptive closed- and open-loop control responses is used to maintain a margin of safety between the operating point and the surge limit. Both the safety margin and the magnitude of the open-loop response are proportional to the rate at which the operating point approaches the surge limit, thus maximizing process efficiency.

Abstract: A method of input power on/off discrimination for an automatic vehicular transmission system having an input shaft to which an output torque of an engine is transmitted, the method being adapted, for example, for the selection of the transmission control logic of the transmission system. The output torque of the engine transmitted to the input shaft is detected. If the detected output torque takes a value such that the rotating speed changing rate of the input shaft during transmission control is higher than a predetermined target value, it is concluded that the engine is in the power-on state. Preferably, the output torque of the engine is transmitted to the input shaft of the transmission system through a driving force transmission apparatus capable of detecting transmission torque.

Abstract: A microprocessor is employed to control a test program which operates to cause a component under test to be filled (or evacuated) to a predetermined pressure P.sub.2 at which a leak test is to be carried out. The test program is arranged firstly to perform a rapid test at atmospheric pressure P.sub.1 to determine the pressure change dpl'/dt in the component due to the temperature fluctuation. The component is then filled (or evacuated) automatically to the test pressure P.sub.T, at which the leak check is carried out. Temperature compensation is achieved by subtracting the value of C dpl'/dt from the pressure change dp.sub.t /dt actually measured, i.e. the actual leak rate dPL/dt is given by ##EQU1## where the constant, C, is generated from an identical proram run, the calibration run, on a known non-leaker with a high temperature fluctuation.

Abstract: In a continuously variable transmission, a target vehicle driving torque is obtained according to engine load, and a target rotational value of the continuously variable transmission possible to output the target vehicle driving torque is determined from a vehicle speed and an engine torque at that time. The target rotational value may be a target rotational speed of an input shaft of the continuously variable transmission, or, a target speed ratio between a rotational speed of an output shaft and a rotational speed of the input shaft. As a result, the target rotational value to which a driver's intention is properly reflected can be set irrespective of condition, i.e., a normal running condition or a speed change transitional condition. Further, it is unnecessary to provide a device such as a throttle actuator for controlling an engine output independently of an accelerator pedal.
