  • Patent number: 8118708
    Abstract: A method for controlling an automated friction clutch arranged in a drive train of a motor vehicle in the force flow between a drive engine (3) and a drive transmission (4), which is configured to close passively by spring pressure and can be disengaged and engaged by way of a pressure-medium-actuated clutch actuator (14), such that the actuation position x_K of the clutch actuator (14) or of an associated transmission element is determined and used for controlling the friction clutch (2). To improve the accuracy and reliability of the clutch actuation it is provided that in addition, an actuating pressure p_K of the clutch actuator (14) is determined and that a required change of the clutch torque M_K to a new nominal value M_K_soll takes place under pressure control, in that the actuating pressure p_K of the clutch actuator (14) is set to a nominal value p_K_soll which corresponds to the nominal value M_K_soll of the clutch torque M_K.

  • Patent number: 8113964
    Abstract: Identification of the tee-off bay (52;53) from which a golf ball landing on a golf-range target (51) originated, is made by calculating an estimate of flight duration (Edurk) of the descending ball as a function of the measured angle (?) of descent in elevation, and, in respect of each ball launched from the bays (52,53), comparing this estimate for a match with a measured interval between the launch of the respective ball and descent of the descending ball. The originating bay (52;53) of the launched ball for which there is the closest match is identified as the origin of the descending ball, and ambiguity or uncertainty between which bay (52,53) is identified is resolved through comparison of the measured angle (?des) of descent in azimuth of the descending ball with estimates (Edirk) of it calculated for each launched ball, and through similar comparison in respect of a calculated decelaration ratio (Edeck) and flight duration (Durk).

    Abstract: A method for operating a drivetrain of a motor vehicle. The drivetrain includes at least a hybrid drive with an internal combustion engine and an electric motor, a clutch arranged between the internal combustion engine and the electric motor, and a transmission arranged between the hybrid drive and a drive output. When the vehicle is at rest, the clutch arranged between the internal combustion engine and the electric motor is filled at least with filling pressure and then, when the vehicle is started, if the starting torque desired by the driver is above a limit value, the internal combustion engine is immediately turned over and started up by the electric motor, whereas, when starting, if the starting torque desired by the driver is below the limit value, then on starting, the internal combustion engine is not turned over by the electric motor.

  • Patent number: 8109376
    Abstract: A device for operating a shifting element of a drive mechanism, having a piston positioned in a piston space to slide between first and second end positions. The piston is operated hydraulically and depends on the hydraulic pressure in the piston space and a force of a resetting mechanism acting on the piston, which opposes the activating force that is equivalent to the hydraulic pressure in the piston space. The transmission capacity of the shifting element is reduced by a force acting on the piston in the direction of the first end position and is increased by a force acting on the piston in the direction of its second end position. The piston is held by a mechanical holder against a force acting on the piston in the direction of the first end position in at least one preset position which is different from the first end position.

  • Patent number: 8105204
    Abstract: A method and a device for controlling a fluid-actuated control system of an automatic or automated transmission of a motor vehicle, which has at least one pressure medium source, at least two control elements that are actuated by pressurized fluid and a control device for controlling the fluid-actuated control system. A further control module is used to reduce; the number and power consumption of valves that are actuated simultaneously to control the control elements; and the mechanical loading of the control elements (1, 2). The control module reads signals concerning at least one current control action and, in accordance with predetermined patterns, calculation rules and/or models, generates signals that cause non-switched control elements to be manipulated by pressurized working fluid.

  • Patent number: 8102137
    Abstract: A method of detecting a useful signal from a measurement signal that is overlaid by at least one interference signal for use in a control or regulating device, where the interference signal occurs with at least one known interference signal frequency. The method including the steps of detecting the measurement signal, performing a Fourier transformation on the measurement signal with reference to the interference signal frequency to detect the interference signal amplitude and phase, detecting the interference signal on the basis of the interference signal amplitude and phase, and removing the interference signal from the measurement signal to detect the useful signal. The Fourier transformation is performed only with reference to the known interference signal frequency to simplify the computation making it possible to detect the useful signal in real time.

  • Patent number: 8095286
    Abstract: A method for controlling a vehicle's automated transmission, which is arranged in a drive train in the force flow between a engine and a drive axle or a transfer box, depending on certain operating parameters and control actions of an adaptive cruise control system (ACC) that can be operated using engine and brake mechanisms to regulate speed and distance from a car in front. The method controls the transmission when an engine torque demand differs from the torque demand of the ACC. The operating mode of the ACC, which is active at the time, and the load direction of the torque demand of the ACC are determined, and the torque demand, used for controlling the transmission when speed or distance regulation is activated, is determined depending on the ACC operating mode and the load direction of the torque demand.
