Patent DE-19754461-A1 (DE)
Title: Automobile automatic transmission control e.g. during garage manoeuvring
Inventor: GASSENFEIT ERIC HANS
IPC: F16H61/04
Filed: 1997-12-08
Abstract: The automatic transmission includes a hydrodynamic torque converter which drives a gearbox. The control system monitors the driven and non driven components of the gear box, the input (turbine) speed of the torque converter, the output torque of the transmission and other parameters. From these the control identifies manoeuvring conditions ie. when the vehicle is being moved by switching direction, moving the transmission from drive to park and vice versa. During manoeuvring the control tries to keep the engine speed near constant and minimises torque shocks. The rate of change of turbine speed is calculated and compared with a target value to generate correction signals for the engine speed. This is achieved by changing the engine timing, by changing the fuel/air mixture etc., and by reference to a programmed table of power train parameters.
Patent DE-19800217-A1 (DE)
Inventor: WIRTH RAINER DR
IPC: G01M99/00
Filed: 1998-01-06
Abstract: The invention relates to a method for automated diagnosis of diagnostic objects, especially drive trains. The method uses a stationary, fully automatic operating data acquisition unit which is arranged on the diagnostic object. The method also uses a monitoring terminal which is spatially separated from said data acquisition unit. The quantitative description of the damaged state and, as a result of which, the activation of data transfer capacity and successive indication of diagnostic statements are initiated on the monitoring terminal by the weighted significance pertaining to a damage characteristic, said significance corresponding to the type of damage, or pertaining to a combination of various damage characteristics. The damage characteristics are specified by the amplitude of the physical quantities belonging to kinematic events. Said quantities are formed for harmonic excitations in the spectrum of the wideband signal which is detected on the machine surface by means of sensors. The quantities are also formed for shock pulse-shaped excitations from the high-pass filtered envelope curve spectrum of the same signal or are formed for the discontinuously occurring determined shock excitations from the maximal value envelope curve spectrum of the same signal. The significance thus describes the relationship of the amplitude pertaining to the damage characteristic for the significance threshold of the damage characteristic, whereby a variable significance threshold is utilized which simply describes the level of significance pertaining to the damage characteristic based on the amplitude of the spectrum lines which surrounds the damage characteristic.

Patent DE-19813957-A1 (DE)
Inventor: BAUER JOACHIM
IPC: B60R21/00
Filed: 1998-03-28
Abstract: The invention relates to an occupant protection system having a central unit, sensors and a plurality of control modules which are connected by means of a bus system so that they can communicate and which are provided for triggering occupant protection devices. In a large number of occupant protection systems, sensors and control modules provided for triggering occupant protection devices considerably increase the amount of wiring required when they are connected to a central unit in a communicative manner. For this reason, bus systems already exist for control modules provided for triggering occupant protection devices. The aim of the invention is to further reduce the amount of wiring required in a simple manner. To this end, the sensors are at least partially integrated in the bus system by means of additional control modules which are assigned to said sensors. In addition, an actual sensor value is sent as a diagnostic response from the control modules of the sensors to the bus system within the scope of a process of the diagnostic inquiry-diagnostic response which triggers a functional test of the control modules provided for triggering occupant protection devices. Said value is processed by the central unit and/or by the other control modules. The invention also relates to the use of these occupant protection systems in motor vehicles.
