  • Publication number: 20140365078
    Abstract: For stabilizing a vehicle, a steering angle of at least one steered front axle and/or additional axle is changed by automatic forced steering. Additional drive stabilization is achievable by initiating an adjustment of a changed steering angle of the steered front axle and/or additional axle in response to a tilting tendency of the vehicle recognized via a tilt-stability control device as above a tilt limit, in addition to initiating a vehicle delay for reducing this tilting tendency. This counteracts an understeering or oversteering influence of the vehicle delay. Additionally or alternatively, additional drive stabilization is achievable by determining the direction of movement in the wheel contact point of an additional axle wheel on the steered additional axle relative to the vehicle's longitudinal axis and adjusting the steering angle of the steered additional axle based thereon to reduce the drift angle of the additional axle wheel relative to its direction of movement.

  • Patent number: 8897985
    Abstract: In a method for controlling the brake-application energy of a vehicle combination having a tractor vehicle equipped with an electronically controlled brake system, at least one front axle and a rear axle, and a trailer vehicle having at least one trailer axle, the functional capability of the electronically controlled brake system is monitored and a status signal is produced as a function thereof. A coupling force control factor is set as a function of the status signal such that, in the event of absent/impaired functional capability of the electronically controlled brake system, a minimal coupling force control factor is set, and the coupling force control factor is set greater than or equal to the minimal control factor, wherein the minimal control factor is not equal to zero and/or is selected such that ascertained separate brake-application energy levels for the tractor vehicle and the trailer vehicle are dependent on a brake-application energy reference value and on axle load distribution.

  • Patent number: 8795136
    Abstract: An actuating device includes a vehicle operating brake and parking brake. A first braking effect is generated by the parking brake independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and a second switched state, wherein the first (full) braking effect of the parking brake is provided. The actuating device further comprises a manually actuatable operating element for actuating the parking brake that comprises travel positions. The actuating device is switched to the second switched state in a first travel position when the parking brake is released, and to the first switched state when the parking brake is applied. Also, the actuating device is switchable to a further switched state. In an actuating method, the actuating device is switched to the further switched state in response to an actuation.

  • Patent number: 8794718
    Abstract: A valve unit for an electro-pneumatic brake control is connected to an input of an air-quantity-boosting valve for the aeration/venting thereof. A double-armature solenoid valve includes primary and secondary armatures each spring-loaded and actuated by a common magnet coil. The primary armature is a switch for a vent valve; the secondary armature is a switch for an intake valve. When the coil is not drawing current, the armatures are in spring-loaded position, the intake valve blocking intake and the vent valve venting. When a first current flows through the coil, the primary armature enters switching position, with the secondary armature in spring-loaded position; the intake valve blocking intake and the vent valve blocking venting. When a second current greater than the first flows through the coil, both primary and secondary armatures are moved into switching positions, so that the intake valve admits air and the vent valve blocks venting.
