Publication number: 20140365078Abstract: 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.Type: ApplicationFiled: September 7, 2012Publication date: December 11, 2014Applicant: WABCO GmbHInventors: Marc Gerecke, Heiko Kopper, Arne Michaelsen

Patent number: 8794718Abstract: 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.Type: GrantFiled: July 4, 2007Date of Patent: August 5, 2014Assignee: WABCO GmbHInventors: Uwe Bensch, Jörg Helmer, Reiner Hölscher, Bernd-Joachim Kiel, Wilfried Menze, Juan Rovira-Rifaterra
