  • Patent number: 10583377
    Abstract: A rain water filter is disclosed. The rain water filter includes a horizontal inlet and a horizontally arranged residual water outlet which are slightly offset in relation to each other. A pipe with a longitudinal slot connects to the inlet and the pipe leads into the residual water outlet. An adhesive filter which is in the form of a tunnel-shaped half-shell is arranged below the longitudinal slot, where the lateral walls are the filter surfaces of the filter. Due to the adhesion effect, the water which flows past is suctioned inwards where it passes through the longitudinal opening into a tank and from there, for example, into a cistern via a filter water outlet. The water running off from the side walls is collected on the base of the hollow cylinder and from there is guided to the residual water outlet.

  • Patent number: 8463516
    Abstract: A process and device for controlling a motor vehicle with an initialization device (43) for startup and a clutch actuated by means of a clutch actuator set (45) between a drive unit and a gear with a control device (41) by means of which at least one control of the clutch actuator set (45) and an acquisition of measurement data of a sensor (47) takes place for the purpose of determining the position of the clutch, characterized in that to verify the state “clutch open” upon startup, a positioning of the clutch actuator set (45) that has been set and stored before or during shutdown is compared to a positioning that was acquired during a predetermined movement course of the clutch actuator set (45) after startup by means of a distance measurement, which takes place at least in a segment of that movement course, whereby the state “clutch open” is recognized, in particular, when the magnitude of the comparison is within a predetermined tolerance range.

  • Patent number: 8150592
    Abstract: A method for preventing spinning of at least one drive wheel in a motor vehicle that has a dual clutch transmission, including the process steps of: a vehicle placed in a first gear unit of the dual clutch transmission; placement of a higher gear for the vehicle in a second gear unit of the dual clutch transmission; detecting whether the at least one drive wheel is spinning; disengaging the clutch that is assigned to the first gear unit, depending on whether spinning was detected; and engaging the clutch that is assigned to the second gear unit, depending on whether spinning was detected.

  • Patent number: 7689340
    Abstract: A method for controlling operation of a parallel transmission comprising two partial transmissions that act upon a common drive shaft and can be coupled to a drive shaft via one respective clutch. The gear ratio of the parallel transmission can be changed from the gear that is engaged in one partial transmission to the gear that is engaged in the other partial transmission without interrupting traction when the parallel transmission functions correctly by opening the clutch of one partial transmission and simultaneously closing the clutch of the other partial transmission. When a malfunction is detected in the actuator of at least one of the clutches, the open clutch can be closed only if at least one of the following conditions is met: the previously closed clutch is open; or, no gear is engaged in the partial transmission allocated to the previously closed clutch.

  • Patent number: 7574296
    Abstract: A process and device for the currentless referencing of a clutch position in non self-locking clutch actuating systems which are switched without current for a first predetermined, passive period of time or until an actuator standstill occurs, in order to verify a clutch reference position, then the clutch position achieved is determined by first measurement and current is supplied to the clutch actuating system for a predetermined, active period of time, the clutch actuating system being then switched again without current for another predetermined, passive period of time or until an actuator standstill occurs, the clutch position being determined by another measurement; finally the measured clutch position is checked to determine whether it can be verified as a new clutch reference position.

  • Patent number: 7448291
    Abstract: To improve the safety of automated gearboxes, it is proposed that terminal positions of internal gearshift members and external actuation members be so defined separately from each other that one can recognize whether the engagement of a speed is accompanied by the attainment of a terminal position of an internal gearshift member or an external actuation member. Error analysis is possible in this way. For dual clutch gears, it is additionally proposed that one can, at least in gearshift operations that are critical in terms of safety, disengage on speed of a subgear in a separate procedure, before a new speed of this subgear can be engaged.

  • Patent number: 7424356
    Abstract: A method for referencing an incremental travel sensor in an electronically controlled actuation device of a clutch in the drive train of a traveling vehicle, the actuation device containing a memory in which a characteristic curve is stored that indicates the clutch torque as a function of the position of an actuation element, the method comprising the following steps: determining whether the clutch is slipping beyond a given threshold; if so, determining the current clutch torque; and determining the current position of the actuation element based on the current clutch torque and the characteristic curve. Additional methods are specified that facilitate a referencing according to requirements.
