Patent EP-0354550-A2 (EP)
Inventor: ZIEGLTRUM WERNER
IPC: G01N27/90
Filed: 1989-08-08
Abstract: A method is indicated for the non-destructive testing of semi-products or of components made of a material which comprises fibre-reinforced plastics, the fibres of which consist of carbon or similar electrically conducting substances. The testing is to be aimed, in particular, at production faults or operating damage, such as delaminations, cracks, fractures, separations or the like. In this case, electrical and magnetic properties of an eddy current measuring probe and a testing frequency for operating the eddy current measuring probe are to be matched to the material. The eddy current measuring probe is moved over the semi-product or component along its surface or placed on different points of the surface. Output signals of a signal evaluation device of the eddy current measuring probe are monitored during this process. A production fault or operating damage is then indicated when the output signals have a value deviating from a mean value or from an expected value. <IMAGE>

Abstract: In an automatic transmission, clutch-to-clutch powered downshifting is controlled by filling the on-coming clutch (C1-C5) at a low pressure while ramping down the off-going clutch pressure until turbine (T) speed is pulled up due to off-going clutch slippage, and then increasing the off-going pressure stepwise to compensate for the change from static to dynamic coefficients of friction. Then the on-coming pressure (Pion) is gradually ramped up and a closed-loop profile control period starts wherein the slip speed of the on-coming clutch is measured and controlled to a slip speed profile by controlling the off-going clutch pressure. When synchronization of the on-coming clutch (C1-C5) is first detected, a closed-loop sync control period starts wherein the off-going pressure (Pioff) is controlled to minimize the slip and the on-coming pressure (Pion) is ramped up at a steeper rate to begin clutch engagement during the sync control period. Adaptive control is accomplished for the initial on-coming pressure by an iterative process which decreases that pressure stepwise until flare occurs and then increases the pressure to stop the flare and repeating the changes in smaller steps to approach the flare condition. Initial off-going pressure is modified when early slip or late slip of the off-going pressure is detected. A modification of off-going pressure step value is effected when the final pressure in the closed-loop period is greater or smaller than the initial pressure. The modifications are targeted to correct fully the respective conditions.
