Patent DE-4329908-A1 (DE)
Title: Method and device for actuating an automatic gear system of a motor vehicle
Inventor: STREIB MARTIN DR
IPC: F16H59/18
Filed: 1993-09-04
Abstract: The invention is based on an automatic gear system, in which changing-up and changing-down processes are triggered at least as a function of a first signal which represents the output r.p.m. of the gear system and/or the engine r.p.m. and/or the input r.p.m. of the gear system and of a second signal which represents the driver's desires in order to set gear transmission ratios. These changing-up and changing-down processes take place with a hysteresis which is typical for the respective changing-up and changing-down process. According to the invention, this hysteresis has a time-dependent portion. Therefore, in addition to a "basic" hysteresis described above between changing-up and changing-down a time-dependent hysteresis is defined. The time-independent basic hysteresis can then be selected to be very small in order to set the optimum gear for the respective operating conditions. This has the advantage that, for example after changing up, the load threshold for a (centrifugal) change-down into the old gear is increased at short notice and after changing down the load threshold for a (centrifugal) change-up into the old gear is reduced at short notice. <IMAGE>

Patent DE-4412746-A1 (DE)
Inventor: FUNK DIETER DIPL ING
IPC: C03B23/03
Filed: 1994-04-15
Abstract: A method for operating a glass pane bending press, in automatic vehicle glazing mfr., involves: (a) lowering a bent glass pane, held by a vacuum holder below the male mould, by downward motion of the upper press crossbeam onto a shuttle ring held at a constant level above the female mould; (b) controlling the downward motion according to a velocity curve having an initial acceleration portion, a max. velocity section and a subsequent deceleration portion for gently laying the pane on the shuttle ring; and (c) designing the curve such that the first diversion of the curve progresses without singularities. The reduced pressure of the vacuum holder matches the pane wt. and the deceleration of the downward motion is adapted to this reduced pressure so that the vacuum holding force is always greater than the counter-force resulting from deceleration and such that the pane is not released from the male mould during deceleration. After redn. or switch-off of the reduced pressure, the pane is laid on the shuttle ring. <IMAGE>
