Lumbar support and control device of a lumbar support and method for controlling a lumbar support of a motor vehicle. An electric control device is provided for a lumbar support which has a drive coupled mechanically to an adjusting mechanism for setting the seat contour of the lumbar support. The control device has at least one computer unit which controls a massaging movement of the lumbar support whereby the massaging movement is characterized through several predefinable ideal speeds. Several ideal speeds for one or more adjusting directions of the lumbar support are controllable through the computer unit. For control by the ideal speeds a drive moment of the drive is adapted to an actual load of the drive so that the massaging movement can be controlled substantially independent of the actual time-changeable or locally variable load. The drive moment is consequently changeable through the control device.

A motor vehicle seat system, control arrangement, actuating arrangement, and process are used to control a lumbar support device of a motor vehicle seat. The lumbar adjustment device has a first drive for adjustment in a first adjustment direction and a second drive for adjustment in a second adjustment direction. The adjustment directions differ from each other. A first adjustment position is ascertained in the first adjustment direction and the drive movement of the second drive is controlled as a function of at least one of the first adjustment position and the temporal change in the first adjustment position.

A motor seat device includes a drive device for displacing a part of the seat in a particular direction. Data for operating the drive device in reaction to a presetting process is stored in a pre-setting memory. A memory drive device controls the drive device according to this operating data. The drive device is further controlled by having a control mechanism process the operating data issued from the drive device during its inertia rotation. The drive device is elastically coupled to the displaceable part so that an at least temporarily asynchronous movement can occur between the drive device and the displaceable part. The position of the displaceable part is determined by evaluating a signal generated by a drive movement of the drive device. The torque of the drive device or a parameter correlating thereto is evaluated to correct a position error caused by the asynchronous movement.

A method for controlling a vehicle seat adjuster in an adjusting path having a first mechanical stop and a second mechanical stop. A user sets an adjustment position of the adjuster inside the adjusting path. A protective stop is also automatically set in the adjusting path in the vicinity of the mechanical stops or another mechanical block blocking the adjusting path. The protective stop causes the adjusting motion to be reduced or stopped upon reaching of the protective stop. This helps produce a smooth braking of the vehicle seat and reduces the mechanical strain on the mechanical stops. The protective stop may be corrected with an updated protective stop. The updated protective stop is maintained despite any user action if a condition dependent on the adjusting motion of the adjuster is fulfilled. Learning regions within the adjusting path are provided to allow the setting of updated protective stops within the learning regions.

A method for driving a drive assembly in a drive system having an automatic transmission and an automatic clutch optionally coupling the drive assembly to the automatic transmission in order to transmit torque includes the following steps. Sensing whether a procedure, in particular a gearshift operation, is to be conducted. After the procedure has been sensed, predefining, for at least one time segment of the procedure which is to be carried out a prediction profile for an operational variable that characterizes the operating state of the drive assembly. And, driving the drive assembly based on the predefined prediction profile of the operational variable to minimize a deviation between the operational variable and the prediction profile.

To be able to verify the function of the actuator system of an automatic clutch or of an automatic transmission of a motor vehicle as a function of the current conditions, including while the motor vehicle is in motion is necessary, the invention teaches that a test circuit actuates the actuator system, starting from a first specified operating position of the clutch or of the transmission to a second specified operating position of the clutch or of the transmission, into an actuator test position in which the clutch or the transmission is still essentially in its first operating position. The test circuit, in the actuator test position, tests the functional capability as a function of data stored in a data memory, which stored data are compared to data measured in the actuator test position of a changing operating parameter.
