The present invention relates to a control circuit for controlling the driving stability of a vehicle where the input quantities determining the course of track are input in a vehicle model circuit which determines at least on nominal value for a control quantity subject to parameters memorised in the vehicle reference model on the basis of a vehicle reference model reproducing the characteristics of the vehicle.

In a filtration system, in particular for cleaning the intake air of a gas turbine, including a flow channel surrounded by walls with an inflow opening and an outflow opening, a partition wall with at least two openings between a dirty side and a clean side which is positioned between the inflow opening and the outflow opening and limited by the walls of the flow channel, and at least two filters for purifying a flowing fluid. At least one filter is installed at a first opening on the dirty side of the partition wall and at least one filter at a second opening on the clean side of the partition wall.

A method for a Sensitive Electronic Stability Program (SESP) presents a general approach for the correction of maneuvers of turning into a bend at low speed. It integrates existing methods as well as subsequent extensions. SESP supplements the standard active yaw control (AYC) function. This allows the SESP to use variables and mechanisms of AYC, on the one hand. On the other hand, AYC continues operating unimpeded in the background and will intervene as usual when SESP cannot stabilize the vehicle appropriately. When the standard AYC intervenes, SESP control operations are forbidden, or running SESP control operations are stopped. This stop can take place either abruptly or (which is more comfortable) by way of a moderate decrease of the correcting variables.

The invention relates to a method for controlling the driving stability of a vehicle, wherein it is determined when a stable or unstable driving behavior prevails whether a tendency to a subsequent unstable driving behavior exists as a result of a highly dynamic inward swerve. In order to provide a method for controlling driving stability, which allows a reaction to predicted unstable driving situations by means of an intervention diminishing or avoiding critical driving situations, the steering force and/or the steering angle of a steering handle is corrected in this case in such a manner that when the steering handle is operated, the driver is assisted in the direction of an understeering vehicle course.

In the process and an extrusion device for producing a foamed polymer, a polymer is melted and a foaming agent is added to the polymer melt. After the polymer melt and the foaming agent have been mixed, a throttle generates a pressure drop for nucleation for gas bubbles or cells. The mixture is then shaped, foamed and cooled. In order to produce high-grade foamed polymer with a microcellular or sub-microcellular structure continuously without any shaping limitations, the throttle controlling the flow rate has a passage control so that the flow rate can be adjusted independently of the pressure drop.

A filter cassette (1) for removing particles from an air stream, in particular from a gas stream entering a gas turbine, has an upstream end (14) and a downstream end (16) and comprises a mounting frame to which a filter media (4) is fitted and which has a mounting face (5) adapted for mounting the filter cassette to an opening (15) of a partition (6). The mounting face is positioned between the filter cassette's upstream and downstream ends at a first distance (Dup) from said upstream end (14) and a second distance (Ddown) from said downstream end (16). The first and second distances each amount to more than 10% of an overall length of the filter cassette. Preferably, the mounting face (5) is positioned centrally between the upstream and down-stream ends (14, 16), approximately in a barycenter line of the filter cassette (1). The filter cassette thus extends to both sides of the partition opening (15). Filter surface area is increased and torque induced by the filter cassette (1) into the partition (6) is reduced.
摘要:
The present invention relates to a method for modifying a driving stability control of a vehicle wherein the input variables essentially composed of the predetermined steering angle (δ) and the driving speed (v) are converted into a nominal value of the yaw velocity ({dot over (Ψ)}nominal) on the basis of a vehicle model defined by running characteristics. The nominal value is compared with a measured actual value of the yaw velocity ({dot over (Ψ)}measured), and an additional yaw torque (MG) is calculated in an ESP controller according to the result of the comparison and used to define an ESP intervention which produces an additional yaw torque by way of pressure quantities applied to the wheel brakes of the vehicle.
