摘要： To simulate freewheel operation, that is to allow torque transmission in one direction only, the variation with respect to time of the torque transmitted by a friction coupling clutch or brake band) is computed and the coupling is released when the transmitted torque passes through zero. When the coupling is slipping, the time at which the torque passed through zero is taken to be the time at which the input and output speed of the coupling are the same. When a slipping and a fully engaged coupling are connected in parallel, the torque transmitted by the fully engaged coupling is computed from a set of equations utilizing only parameters sensed in any case in a standard drive system. Speed sensors and a torsiometer furnish signals required for the computations. Preferably, the computations are implemented by a microprocessor.

摘要： A method of operating a hydraulic pump of a drive train of a motor vehicle having a transmission with a hydrodynamic torque converter and a engine, with the input speed of the hydraulic pump being adjusted depending on the speed of the engine. The input speed of the hydraulic pump is adjusted depending on the pump speed of the torque converter, which corresponds to the speed of the engine and depends on the turbine speed of the torque converter, such that when the pump speed of the torque converter is higher than the turbine speed of the same, the hydraulic pump is operated at a speed higher than the speed of the engine. When the turbine speed of the torque converter and the pump speed of the same equalize, the excessive increase in the input speed of the hydraulic pump is reduced in relation to the speed of the engine.

摘要： An automatic transmission control unit determines whether or not a constantly open failure, in which a switch valve cannot switch a pressure regulating valve and a second hydraulic chamber to a non-communicative state, has occurred on the basis of a parameter (an inertia phase time, for example) representing a dynamic characteristic during a shift from a first gear position to a second gear position. The determination of the constantly open failure is begun after initial variation in the parameter representing the dynamic characteristic during the shift has been eliminated through learning control in which the dynamic characteristic during the shift is caused to approach a target dynamic characteristic.
