  • Patent number: 7818107
    Abstract: A method for controlling the driving dynamics of a vehicle provides that a steering movement is carried out on the basis of a set value, which is calculated as a function of a deviation between a desired value and an acquired actual value of a vehicle state variable. In this method, at least one membership degree of an acquired value of a steering angle, which is set by a driver, and/or of a steering angle gradient, which is set by the driver, in a predetermined fuzzy set, are/is determined, and a value of the set value is changed as a function of the membership degree.

  • Patent number: 7792620
    Abstract: A device for controlling the driving dynamics of a vehicle senses at least one driving condition variable being representative of a driving condition and has a driving dynamics controller for determining an additional steering angle, according to which a steering motion can be carried out in addition to the steering motion commanded by an operator. The driving dynamics controller (100, 110) has at least two control units (340, 350), which are respectively associated with one driving condition range. It includes a determinator for determining a prevailing driving condition, in which the prevailing driving condition can be established based on the driving condition variable ({dot over (?)}, {dot over (?)}, ay), and in that it includes an activation logic (360) being in connection with the determination means and being adapted to enable a control unit (340, 350), which is associated with the established driving condition range.

  • Publication number: 20080294355
    Abstract: A method for calculation of the lateral force in a motor vehicle with an electromechanical or electrohydraulic steering system is disclosed. The method comprises the following steps: firstly a steering column force is recorded, from which a total restoring torque is calculated. The total restoring torque comprises restoring torques generated by differing forces acting on the wheels. Said restoring torques include a restoring torque generated by lateral force and other restoring torques. The other restoring torques are quantitatively determined on the basis of measured values and subtracted from the total restoring torque, in order to determine the restoring torque generated by lateral force. Finally the lateral force is determined from the restoring torque generated by the lateral force.

  • Publication number: 20060100766
    Abstract: In a method for increasing the driving stability of a vehicle during braking, compensation steering angles for a regulated and/or controlled steering system are calculated from several input parameters, so that the driving stability of the vehicle is increased by steering interventions. During the steering interventions at least two interference compensation portions for the compensation steering angles are taken into consideration in order to obtain a more comfortable control, from which an interference compensation portion is calculated on the basis of the vehicle course.

  • Patent number: 5794298
    Abstract: The invention relates to a device for handling a brush head for cleaning the surfaces of large objects like aircraft, ships or buildings. The handling device has a multi-joint assembly carrying a brush head (18) on the end extension (14) of an angled mast (13) having, extending from the end extension (14), three motor-driven rotary units (60, 62, 64) arranged one behind the other and having alternately perpendicular axes (60', 62', 64') and a motor-driven telescopic linear unit (66') secured to the last rotary unit (64) and aligned with its axis of rotation (64'). In order to ensure that the brush roller is always perpendicular to the surface to be cleaned along its entire travel, even at points which are difficult of access, the invention proposes that axes (60', 66') of the rotary unit (60) on the end extension side and of the linear unit (66) be arranged in laterally staggered, mutually parallel planes.

  • Patent number: 5720069
    Abstract: The invention relates to an arrangement for cleaning the surfaces of aircraft with a large manipulator having a rotating brush head consisting of several extensions (12, 12', 12", 14) pivotable on articulations (20, 22, 24, 28) by means of hydraulic drive systems (30) and fitted on a rotary bracket (11) of a motor-driven chassis (10) with its base extension (12) fitted on an angled mast to rotate about a main axis (11) and a multiple articulation (16) on the end extension (14) at the free end. To provide starting auxiliary for the chassis (10), the adaptation of the large manipulator to the aircraft and/or monitoring facilities for the cleaning process, there is an opto-electronic distance camera (40) and a computer-supported electronic evaluation system to which the output signals of the distance camera (40) are applied.

  • Patent number: 4375161
    Abstract: Disclosed is a device for opening a flanged joint of the type wherein one or more flange extensions on one flange part of the joint are bent around into engagement with the other flange part of the joint. A first leg member including a first generally tapered end portion is adapted to enter behind the bent-around flange extension of the flanged joint and engage the end of the bent-around flange extension. A second leg member includes a first end portion cooperating with the first end of the first leg member and having a generally flat contact surface on its side facing the first end portion of the first leg member, with the flat contact surface being adapted to engage and support the outer circumferential surface of the flanged joint. Preferably, the device includes a fluid cylinder attached to the second ends of the first and second leg members for selectively producing relative rotation of the leg members with respect to each other about a hinge connection.
