20090255773 | ACTUATOR ARRANGEMENT FOR A MOTOR VEHICLE CLUTCH - An actuator arrangement for a clutch of a drive train for motor vehicles. The clutch is prestressed into an opened position and can be activated electromechanically. An electric motor can be coupled to the clutch in order to activate it. A control unit actuates the electric motor. The actuator arrangement has a safety device which is connected to the electric motor parallel to the control unit. The safety device is configured, in the case of a fault state, to supply electrical power to the electric motor independently of the control unit in order to open the clutch. | 10-15-2009 |
20100152986 | METHOD FOR CONTROLLING A DUAL CLUTCH TRANSMISSION - A method for controlling dual clutch transmission with at least two partial drive trains, each arranged to be coupled with an engine by means of a clutch, in that, a first clutch of an actively operated partial drive train currently transmitting torque is opened, whereas a second clutch of the partial drive train not actively operated is closed in the already engaged gear and determining a reduction of a maximum possible lateral guiding force of at least one drive wheel and determining torque transmitted by the clutches, wherein, in the case of reduction of the maximally possible lateral guiding force below a default value and in the case that torque is transmitted by both clutches, the torque of one of the clutches is reduced. | 06-17-2010 |
20100305802 | FAULT-DETECTION METHODS FOR MOTOR VEHICLE GEARBOXES - A method for detecting a fault state in an automated motor vehicle gearbox having two parallel branches. Each branch has a clutch and is configured to transmit driving torques from a drive unit to at least one driven wheel of the motor vehicle. The method comprises the steps of sensing whether both clutches are at least partially closed; of sensing the rotational speed of the at least one driven wheel and sensing the rotational speed of a non-driven wheel, and of detection of a fault state if both clutches are at least partially closed, and a difference between the rotational speeds of the wheels is greater than a predetermined reference value. | 12-02-2010 |
20110004383 | METHOD FOR MONITORING A DRIVE TRAIN - A method for monitoring an automated drive train of a motor vehicle, in particular of a passenger car. The drive train comprises a drive engine, a friction clutch arrangement and a multi-speed transmission. The friction clutch arrangement connects or disconnects the drive engine to/from the multi-speed transmission. The method comprises the step of determining at least one rotational speed parameter of the drive train; checking whether the rotational speed parameter is greater than a first threshold value for a first predetermined time interval, and initiating a measure in the drive train in order to lower the rotational speed parameter if the rotational speed parameter is greater than the first threshold value for the first predetermined time interval. | 01-06-2011 |
20140052326 | METHOD AND CONTROL DEVICE FOR A DRIVE TRAIN COMPONENT - A method for actuating a component of a drive train of a motor vehicle. The component is mechanically prestressed into a safe state. The method has the steps: sensing a fault state; sensing whether the fault state is a first or second type of fault state; immediate interruption of the actuation of the component so that the component is passively transferred into the safe state by the mechanical prestress if the fault state, is of the first type of fault state, or actuation of the component in such a way that the component is actively transferred into the safe state if the fault state is of the second type of fault state. | 02-20-2014 |

20120325166 | CASTING CORE FOR FORMING A COOLING CHANNEL IN A PISTON - A soluble and substantially ring-shaped casting core may include a cooling channel in a piston having at least one inflow and at least one outflow. The casting core may form a closed ring and the inflow may be arranged directly adjacent to the outflow. The casting core may have a cross-sectional taper for forming a choke in the circumferential direction between the inflow and the outflow. | 12-27-2012 |
20130036997 | PISTON - A piston for an internal combustion engine may include a piston head and a piston shaft. The piston shaft may have two shaft walls, one arranged on a pressure side and the other arranged on a counter-pressure side. Two box walls may have pin bosses and connect the shaft walls. Each of the box walls may have a first partial wall section and a second partial wall section. The first partial wall section may extend between the pin boss and the shaft wall arranged on the pressure side. The second partial wall section may extend between the pin boss and the shaft wall arranged on the counter-pressure side. A first longitudinal centre line of the first partial wall section is may be convergent to a second longitudinal centre line of the second partial wall section, wherein the first and second longitudinal centre lines—intersect each other outside the piston. | 02-14-2013 |
