  • Patent number: 6439675
    Abstract: Proposed are a method and a device for controlling a braking system of a vehicle, braking force being maintained in at least one operating state at least one wheel of the vehicle while the braking pedal is actuated, independently of the degree of the pedal actuation. In this context, different conditions are provided jointly or alternatively for activating or deactivating the function.

  • Patent number: 6056373
    Abstract: The invention is based on a system for controlling the braking action in a motor vehicle by means for adjusting the braking action independently of the driver's actuation. Upon recognition of a preselectable operating mode, for which at least the longitudinal velocity of the vehicle is found to be zero, a certain braking action is exerted. An operating mode of the type in question can be present when, for example, the above-mentioned creep suppression or the above-mentioned hillholding is desired. The core of the invention consists in that, upon determination of a preselectable longitudinal vehicle velocity during this operating mode, the braking action is increased independently of the driver. As a result of the monitoring of the longitudinal vehicle velocity according to the invention during the operating mode (creep suppression mode or hillholder mode), any motion of the vehicle unwanted by the driver is reliably prevented.

  • Patent number: 6019442
    Abstract: In a method of controlling a braking system in a vehicle, the action of the brakes is distributed between at least one front and one rear wheel by adjusting at least the braking pressure in the brakes on one of the rear wheels in order to establish a difference between the braking pressure on the front wheel and that on the rear wheel. The difference established between the braking pressure on the front wheel and that on the rear wheel is decreased in the presence of a prescribable condition. The presence of the prescribable condition depends at least on a detected parameter that represents the longitudinal velocity of the vehicle, and the established difference is continuously decreased.

  • Patent number: 6009984
    Abstract: A hill-holder function is initiated when the brake pedal is actuated while the vehicle is in at least one operating state. The braking force is thus locked into at least one wheel brake independently of the extent to which the pedal is actuated. This braking force is decreased again when the brake pedal is released.

  • Patent number: 5791628
    Abstract: An electromagnetically actuatable valve that reduces the locking force of the valve has a seat valve, which can be transferred to a closing position counter to the force of a prestressed restoring spring. A valve seat communicates with an inflow side, and a closing member disposed on a tappet communicates on the outflow side of the valve. A magnet armature cooperates with the tappet in a valve dome which communicates with the outflow side. The magnet armature and the tappet are two separate components which positively support one another. On the inflow side, a longitudinal bore of the tappet originates at the closing member, and a first longitudinally movable pin is receive therein largely in a pressure-tight fashion. The cross section of the first pin is at least approximately equivalent to the sealing cross section of the valve seat. The longitudinal bore of the tappet is continued in the magnet armature. A second pin is received in that longitudinal bore.
