摘要： In executing a clutch-to-clutch gearshift based on the release and engagement of two clutches by the control of the hydraulic pressures of the clutches, the fluctuating magnitude of the output shaft r.p.m. (No in FIG. 2) of the automatic transmission is calculated, and the degree of the drag (tie-up) state of the clutches is detected on the basis of the calculated fluctuating magnitude. As a result, the pressure increasing/decreasing timings of the hydraulic pressures of the clutches can be optimized to realize a feedback control or learning control of higher precision.

摘要： In a gearshift control apparatus for an automatic transmission which performs a downshift under power ON state, after a command for a clutch-to-clutch downshift has been issued, the hydraulic pressure of a higher-speed-stage side clutch is first lowered to raise the input r.p.m. of the transmission. When the beginning of rise in the input r.p.m. of the transmission has been detected, the hydraulic pressure of the higher-speed-stage side clutch is subjected to a feedback control so that the change rate of the input r.p.m. of the transmission may become a specific value. Upon the detection that the input r.p.m. of the transmission have come near to the synchronous r.p.m. of a lower speed stage, the hydraulic pressure of the lower-speed-stage side clutch is gradually raised, and simultaneously, the hydraulic pressure of the higher-speed-stage side clutch is subjected to a feedback control on the basis of the input r.p.m. of the transmission.

摘要： A control apparatus for an automatic transmission of twin clutch type, in which a skip downshift is executed with a light gearshift shock and in a short gearshifting time period. As illustrated in FIG. 1, after the release of a clutch C2, a command for switching over a synchro mechanism is issued at a time t3. When the r.p.m. NT of a turbine has reached the synchronous r.p.m. NT3 of the intermediate stage of the skip downshift, the oil pressure of a clutch C1 is raised in order that the rising rate of the turbine r.p.m. (speed) NT may become a predetermined value d/dt(NT1) or d/dt(NT2). Thereafter, the oil pressure of the clutch C1 is controlled in order that the turbine r.p.m. NT may maintain a value NT2 (synchronous r.p.m. of the lower speed stage of the skip downshift)+.DELTA.NT4. After the completion of the switchover of the synchro mechanism, the oil pressure of the clutch C2 is gradually raised, and that of the clutch C1 is gradually lowered. Thus, the skip downshift in a power-ON state is executed.

摘要： The slip control system of a lockup clutch including a lockup relay valve and a duty solenoid (50). The lockup relay valve switches the engagement state of the lockup clutch in response to the actuation of a switching solenoid. In the state in which the lockup relay valve is switched to a position for exhausting working oil out of a release side oil chamber in a torque converter, the duty solenoid receives a duty factor correspondent to the desired value of a slip magnitude as delivered from a controller (58) and then controls the quantity of exhaust of the working oil. Thus, the slip control system can attain a reduced cost and a smaller size as well as a lighter weight while being enhanced in reliability and controllability.

摘要： A fuel injection control device in which the amount of fuel injected by the fuel injector is increased at the time of acceleration. Namely, at the time of acceleration, the lean time and the rich time of the air-fuel mixture are calculated during the lean-rich discriminating time, which is basically equal to a time of an occurence of the lean time and the rich time when the air-fuel ratio is maintained at the stoichiometric air-fuel ratio at the time of acceleration. When the lean time becomes considerably longer than the rich time, the amount of fuel injected by the fuel injector is further increased.

摘要： A method for controlling fuel injection rate in internal combustion engine in accordance with the intake pressure and the engine speed. The method has the steps of determining the intake pressure using, as a variable, the period of time after a change in the throttle opening, and computing a basic fuel injection period on the basis of the thus computed intake pressure and the engine speed. The fuel injection is conducted by a system in accordance with this method. The system determines the intake pressure in the steady state of engine operation in accordance with the throttle opening and the fuel injection rate, effects a correction on the thus determined intake pressure so as to take into account a delay in response of the intake pressure to the transient period, and determines the basic fuel injection period on the basis of the corrected intake pressure and the engine speed. With this method and system, the fuel injection rate can be controlled in a high degree of conformity with the injection rate demanded by the engine, because the injection rate is determined on the basis of the engine speed and the actual intake pressure which can be predicted with a high degree of precision.
