  • Publication number: 20110264341
    Abstract: A method for controlling a drive train with at least one drive unit, in particular for a vehicle is disclosed. A setpoint value for a torque of the at least one drive unit can be predefined. The actual value of this torque is detected and a first signal is generated which ensures reliable operation of the drive train if the deviation of the actual value from the setpoint value is greater than a predefinable absolute value of the deviation value and/or the deviation of the actual value from the setpoint value lasts for longer than a predefinable absolute value of the deviation time period.

  • Publication number: 20110264974
    Abstract: In a method for operating a communication system having a plurality of nodes which have access to a shared channel, a transmission process for transmitting a message via the channel is monitored for bit errors, and when a bit error occurs, a signaling message is transmitted via the channel in order to signal the bit error. In order to allow communications processes between the nodes to be controlled as a function of a bit error rate of the channel, a signaling rate of the signaling messages is measured and a bit error rate of the channel is determined as a function of the signaling rate.

  • Patent number: 8042884
    Abstract: The invention relates to a hydraulic vehicle brake system having a service brake which can be actuated by muscle force and having a device for regulating the wheel slip. It is proposed in such a vehicle brake system to use suction pumps in connection with specially-designed accumulators. The accumulators have separating elements which in each case separate a first accumulator chamber from a second accumulator chamber. An inflow opens out into the first accumulator chamber, and an outflow, which is separate from the inflow, outlets out of the first accumulator chamber. The separating element is arranged so as to be freely movable between two end positions, and in one of its end positions, blocks a pressure medium connection of the inflow to the outflow.

  • Publication number: 20110252958
    Abstract: A machine housing of a piston machine is disclosed. The machine housing is formed in two parts. The machine housing has a main housing which is closed off by a connection plate. Here, the connection plate is screwed to the main housing by means of a plurality of screws, and is positioned with low tolerances with respect to said main housing by means of two centering pins. Here, the centering pins are arranged with twofold rotational symmetry with respect to a shaft axis of a drive shaft of the piston machine. In contrast, screw positions do not have rotational symmetry with respect to said shaft axis. This prevents incorrect mounting of the connection plate.
