摘要： A plurality of characteristic variables concerning the rotational speed are detected so as to be used for inference, and the plurality of characteristic variables are divided into a plurality of sets. Groups of rules each indicating the relationship between the characteristic variable corresponding to each set and an amount of gain adjustment, as well as the relationship between the magnitude of the characteristic variable corresponding to each set and the degree of adoption of the amount of gain adjustment, are stored. When it is determined that each of the characteristic variables cannot be controlled within a permissible range, the relationship between each of the characteristic variables of the groups of rules and the amount of gain adjustment is corrected in such a manner that the permissible range is broadened. The amount of gain adjustment for each set is inferred on the basis of the characteristic variable detected and each group of rules, and the degree of adoption of the amount of gain adjustment is determined for each of the sets in correspondence of the manipulated variable of the respective characteristic variables. On the basis of the result of inference of the amount of gain adjustment and the degree of adoption, an amount of gain to be adjusted is determined by calculating a weighted average value of the result of inference of the amount of gain adjustment with the degree of adoption set as weight. This amount of gain to be adjusted is set in a PID controller.

摘要： A controller for a hydraulic fluid flow control apparatus determines a quantity necessary for loading/unloading operations according to a signal from a lever operating degree detector, and controls a variable displacement type hydraulic pump to obtain the quantity. Accordingly, unnecessary hydraulic fluid flow in the hydraulic apparatus is reduced. The controller determines when a vehicle is stopped according to a signal from a clutch ON-OFF detector or a neutral sensor, and can raise the rpm of an engine. Therefore, when the loading/unloading operations are being executed while the vehicle is stopped, there is no need to operate the accelerator pedal.

摘要： An engine speed controlling apparatus for an internal combustion engine for controlling the engine speed of an internal combustion engine which has a mechanism for governing the engine speed and in which a manipulated variable of the governing mechanism and torque are in non-linear relationships. Although a real manipulated variable and the torque are in non-linear relationships, a virtual manipulated variable in which an actual engine speed becomes a targeted engine speed is calculated assuming those relationships as being linear. The virtual manipulated variable is converted to the real manipulated variable by using the actual non-linear relationships between the real manipulated variable and the torque, and the governor is controlled on the basis of the converted real manipulated variable.

摘要： A hydraulic control apparatus includes two oil flow control valves (30, 32) each provided with a supply control portion (36, 38, 52, 54) for controlling an oil supply from a pressurized oil source, and a discharge control portion (40, 42, 56, 58) for controlling connection with a discharge passage. One of those oil flow control valves supplies/discharges oil to/from one of hydraulic chambers (22, 24) that are oppositely formed in a hydraulic servo mechanism. An operation direction of the hydraulic servo mechanism is performed by operating one of the oil flow control valves. The other operation direction of the hydraulic servo mechanism is performed by operating the other oil flow control valve.

摘要： To calculate a vehicle mass based on a driving force caused by an engine, running resistance, and vehicle acceleration, influence of gradient resistance is removed. A gross driving force calculating section calculates a gross driving force F of a vehicle by deducting running resistance from a driving force of a vehicle caused by an engine. An acceleration sensor calculates a longitudinal acceleration &agr; of the vehicle. Relationship among a gross driving force F, a longitudinal acceleration &agr;, a vehicle mass M, and road gradient &THgr; can be expressed as (&agr;=F/M−g sin &THgr;). Because the change of gradient contains only a low frequency component, by processing a gross driving force F and an acceleration &agr;, using a high-pass filter with a predetermined cut-off frequency, the influence of the gradient &THgr; can be removed. Based on the resultant processed gross driving force F and the processed acceleration &agr;, a vehicle mass can be obtained from the above expression without being affected by the influence of the gradient
