  • Publication number: 20080258412
    Abstract: A roll regulation actuator for installation between two axially aligned rods, in particular between two rods of a stabilizer, includes a cylindrical housing and a device arranged in the housing for providing a torque acting on at least one of the rods. The device includes a first piston displaceable in the housing with a first piston rod having a first thread. The device further includes a first ball nut rotatably mounted in the housing. The first ball nut engages the first piston rod via a first counter-thread matching the first thread, and is able to be coupled to one end of a first rod. The device further includes a first pressure chamber acting on a first side of the first piston.

  • Patent number: 7392116
    Abstract: A method for operating a chassis regulating system of a vehicle, in which a control quantity is generated for an actuator, includes providing a first signal, which is representative of the transverse acceleration of the vehicle, providing a second signal, which is representative of the steering lock angle, providing a third signal, which is representative of the speed of the vehicle, allocating a weighting factor for the amplitude of the first signal, generating an estimated transverse acceleration signal from the second signal and the third signal, generating a weighted estimation signal by multiplying the estimated transverse acceleration signal with the weighting factor, and generating the control quantity by additive superimposing of the weighted estimation signal with the first signal.

  • Publication number: 20010049577
    Abstract: A method and apparatus for detecting and compensating for wheel brake irregularities includes a unit for detecting a control signal that controls a brake actuator, a unit for detecting changes of the control signal generated by the actuator, and a unit for evaluating control signal changes. The invention provides a cost-effective solution for early identification of brake rubbing, particularly in cases where such rubbing evolves into a problem that impairs driving comfort. Furthermore, the invention has the advantage that an identified irregularity can automatically be used to eliminate the irregularity.
