  • Patent number: 6481981
    Abstract: The present invention relates to a motor-driven assembly with a motor unit and a working machine, wherein the motor unit includes a rotatable rotor with a motor shaft to drive at least one working element. The nub of the present invention is the provision of a holding element which extends through the motor shaft and pivotably mounts the rotor. These measures ensure a space-saving mounting support of the rotor, on the one hand, and a drive of the working machine with practically no vibrations and with little noise in operation, on the other hand. The holding element may be arranged, for example, as a tie rod, between the electric motor and the cover for an electronic unit and may serve for the attachment of the construction units on a pump housing.

  • Patent number: 6478051
    Abstract: The present invention discloses a pressure fluid accumulator with a housing having its interior subdivided into two chambers by a media-separating element, the first chamber being filled with a gas and the second chamber being filled with a liquid, and wherein in a hydraulic port a bottom valve is provided whose closure member is operable by the media-separating element and which permits filling the second chamber with liquid and prevents complete evacuation of the second chamber. In order to prevent a damage of the bottom valve and an inadvertent escape of fluid and, thus, ensure a considerable increase in the reliability in operation, according to the present invention, the closure member can be moved by the media-separating element to adopt a position in which it fulfils the function of a hydraulic piston.

  • Patent number: 6474753
    Abstract: For externally actuating a brake system, both the surroundings of the brake pedal and, if necessary, additional parameters (d,d ,Vref) are monitored a sensor unit (6,10,11). Then the brake pressure (pnom) will be set automatically in an expedient manner in dependence of the individual parameters that were evaluated. Advantageous further embodiments include proposals for precharging the brake or braking slightly or automatically applying a higher brake pressure in dependence of the measuring results, in so far as this is reasonable with respect to road conditions and the driver's wishes as they were assumed by the system.

  • Patent number: 6474149
    Abstract: The invention provides a method of detecting a defective condition on a pressure switch arrangement which at least assumes a defective condition on the said pressure switch assembly whenever a signal arrives at an input of an electronic computing unit which cannot be associated either to the opened or to the closed condition of the pressure switch. Moreover, a defective condition on the pressure switch arrangement mounted in the brake system of a vehicle is assumed, once the pressure switch signal refers to an actuated brake although the vehicle is significantly accelerated. Conversely, a defective condition is also assumed if the vehicle significantly decelerates although the pressure switch signal refers to a lack of brake pressure. Also, an appropriate pressure switch arrangement is provided which, with the pressure switch closed, generates a rectangular signal and, with the pressure switch opened, generates a high level on the input II of an electronic computing unit.

  • Patent number: 6473681
    Abstract: The invention concerns a process for shortening the braking distance of a vehicle equipped with a brake servo unit which during a standard braking action is only triggered by the brake pedal pressure caused by the driver and in case of a critical driving situation is so triggered by a control device that in comparison to the standard braking action an increased amplification factor is set at the brake servo unit. The invention distinguishes itself by the fact that a danger potential is determined, stating the probability that the vehicle to be braked will be involved in an accident and that the increase of the amplification factor is controlled in accordance with the danger potential.

  • Patent number: 6470731
    Abstract: The present invention relates to a method and a device for determining a characteristic quantity for an instantaneously maximum coefficient of friction between the tires of a vehicle and a roadway, which is calculated from the ratio between the frictional force and the wheel contact force, especially for defining a following time of the vehicle in relation to another vehicle which is directly in front thereof in the direction of travel, for collision avoidance purposes. In this arrangement, the characteristic quantity of the coefficient of friction is assigned to one of at least two classes and is then presented to a driver of the vehicle and/or sent to the collision avoidance system of the vehicle, by logically linking data output values of sensor means provided in the vehicle, on the one hand.
