Patent DE-19734912-A1 (DE)
Title: Method for torque dependent decoupling of positioning drive
Inventor: FENGLER FRANK DIPL ING
IPC: H02H7/085
Filed: 1997-08-12
Abstract: The method involves measuring the rotational velocity of the motor axle and the drive motor current supply. The current value and rotational velocity are combined to determine the drive torque, which can then be used to change the current supply to the motor and control the rotational velocity. The drive is switched off as soon as the torque exceeds a threshold. The device may be improved by incorporating gear path and parameters so that the drive may be switched off as soon as a torque that is gear path dependent exceeds a threshold.

Patent DE-19737416-A1 (DE)
Title: Hydraulic control system for automatic gear with friction elements for each gear stage
Inventor: YU PYUNG HWAN
IPC: F16H61/14
Filed: 1997-08-27
Abstract: The system has a control which adjusts the hydraulic pressure produced by the hydraulic pressure source to a constant line pressure. A control produces reduced pressure by reducing the hydraulic pressure from the source. A damping clutch control supplies hydraulic pressure to a torque converter (1) by controlling the reduced pressure produced by the reducing pressure control. A shift control converts the hydraulic pressure produced by the line pressure control into a drive pressure for each gear stage.  A hydraulic control controls the drive pressure. A pressure distributor supplies the hydraulic pressure from the hydraulic control to each friction element (59,61,63,65, 79) for each gear stage. A regulating valve (7) adjusts the line pressure. A high and low control valve (9) is controlled by the reducing pressure, damping clutch and third-gear driving pressure.
