Patent number: 5813940Abstract: An arrangement for the controlled engagement and disengagement of a clutch in the transmission of a motor vehicle drive system includes an engine and an automatic transmission which can be activated electro-hydraulically. In order to avoid "stationary-state shaking", a preselected value for the clutch slip torque is determined as a function of a prehistory of limited duration in the form of an evaluation of the speed profile of the motor vehicle in the immediate past.Type: GrantFiled: April 29, 1997Date of Patent: September 29, 1998Assignee: Volkswagen AGInventors: Norbert Ramm, Frank Zimmermann

Patent number: 5439425Abstract: A motor vehicle includes a drive system consisting of an engine and an electrohydraulically actuatable automatic transmission connected to the vehicle body by resilient mounts. To reduce stationary vibration of the vehicle and engagement and disengagement shock, the engagement pressure of a clutch in the transmission is controlled so that the clutch begins to slip when the strain between the drive system and the vehicle body reaches a selected value. The strain is determined by detecting the displacement of the drive system with respect to the body or the torque in the drive system or the stress in the resilient mounts.Type: GrantFiled: August 23, 1993Date of Patent: August 8, 1995Assignee: Volkswagen A.G.Inventors: Norbert Ramm, Frank Zimmermann

Patent number: 5142133Abstract: The lowering and raising of slats of a venetian blind are controlled by control signals from a photodetector circuit which is mounted adjacent to the venetian blind and which acts responsive to predetermined limit values of the background brightness being exceeded. Following lowering of the venetian blind, control of the closing or screening angle of the slats is provided by a sun-tracking photodetector affixed to a slat and operating in dependence upon the angular alignment of the slat. In order to fix the closing angle of the slats at a selected value, subsequent adjustment of the slats is controlled by the sun-tracking photodetector which can, in turn, be controlled externally by a manually operated keying mechanism. The photodetector used in measurement of background brightness comprises three aligned photodiodes which are directed skyward in three different directions and which together detect the incident light over the full range of 180.degree. in front of the venetian blind.Type: GrantFiled: April 23, 1991Date of Patent: August 25, 1992Inventors: Michael Kern, Gunter Ruckstetter, Ekkehard Schull, Frank Zimmermann

Patent number: 4543855Abstract: A method for operating a vehicle having an automatic, continuously variable speed transmission comprising at least three control phases. During a first control phase, the engine speed is maintained at a substantially constant value while the transmission gear ratio is increased to the maximum transmission gear ratio. During a second control phase, the transmission gear ratio is maintained at the maximum transmission gear ratio while the engine speed is increased to the maximum engine speed possible at the maximum gear ratio and selected throttle valve angle. During a third control phase, the transmission gear ratio is decreased from the maximum transmission gear ratio, so that higher vehicle traveling speeds may be obtained. During the third control phase the transmission gear ratio may be rapidly changed to a ratio corresponding to maximum engine power when the accelerator pedal is placed in a kickdown position.Type: GrantFiled: March 31, 1983Date of Patent: October 1, 1985Assignee: Volkswagenwerk AktiengesellschaftInventors: Hermann Oetting, Paulus Heidemeyer, Frank Zimmermann

Patent number: 4331226Abstract: Apparatus for automatic actuation of a clutch of an automobile with a manual shift transmission. A pneumatic servo motor controls clutch engagement. A control mechanism, for example a microprocessor, controls the servo motor as a function of accelerator pedal position and/or input and output clutch speeds during starts from stop (initial transmission input speed .perspectiveto.O). The rotation speed of the engine attains a prescribed value preassigned as a function of the accelerator pedal position. For each pedal position, signals to control valves cause the servo motor to vary clutch engagement based on the difference between prescribed and detected engine speeds. The signals can be pulse signals variable in frequency and/or duration by the control mechanism. During starting from stop, for pedal depressions above idle, the rotational speed of the engine remains below maximum tractive power for that pedal position.Type: GrantFiled: July 3, 1980Date of Patent: May 25, 1982Assignee: Volkswagenwerk AktiengesellschaftInventors: Paulus Heidemeyer, Frank Zimmermann, Romanus Scholz

Patent number: 4295551Abstract: An automatic clutch system is provided for use in a motor vehicle and has a control mechanism which responds to the position of the accelerator pedal and which also responds to first and second rotation speed sensing means connected to the engine shaft and the transmission shaft. In a preferred embodiment, the automatic clutch system is provided with a control mechanism which operates in a first mode when the vehicle is starting from a standing position to engage the clutch in a manner which keeps the engine in a specified speed range, which depends on accelerator lever position. The control mechanism operates in a second mode when the vehicle is shifted between gears in order to engage the clutch in a manner which provides a constant time gradient for the shaft speed difference selected in accordance with accelerator pedal position.Type: GrantFiled: July 26, 1979Date of Patent: October 20, 1981Assignee: Volkswagenwerk AktiengesellschaftInventors: Frank Zimmermann, Paulus Heidemeyer, Erhard Bigalke
