Patent number: 9457775Abstract: A control unit of a vehicle brake system has a receive circuit for tapping and processing a digital signal provided by an active speed sensor for speed measurement on a vehicle wheel. The signal includes information concerning the speed of a pole wheel, which is arranged in front of the sensor, spaced therefrom by an air gap, and which rotates along with the wheel. The signal also includes an actual air gap value digitized in stages and comprising several bits. The control unit also has a comparator circuit for comparing the actual air gap value to a reference air gap value and for determining whether the actual air gap value exceeds the reference value by more than a defined tolerance value. An information circuit of the control circuit generates early warning information when the comparator circuit determines that the actual air gap value exceeds the reference value by more than the tolerance value.Type: GrantFiled: October 31, 2013Date of Patent: October 4, 2016Assignee: WABCO GmbHInventors: Andreas Goers, Marco Michel, Otmar Struwe

Patent number: 9459347Abstract: An environment monitoring system for a vehicle includes at least two distance sensors for detecting distance by measuring the propagation time of detection signals. The distance sensors are each designed as a transmitting unit and receiving unit for the detection signals and, in a direct operating mode, emit detection signals, receive reflected components of the detection signals emitted by the distance sensors; and emit active measurement signals according thereto. The system also includes a control device that receives the measurement signals of the distance sensors and determines the object distance of a detected object. At least one distance sensor additionally can be operated in an indirect operating mode to detect a detection signal emitted by another distance sensor and reflected by the object and to generate an indirect measurement signal.Type: GrantFiled: July 30, 2011Date of Patent: October 4, 2016Assignee: WABCO GmbHInventors: Christoph Lucking, Rainer Risse, Udo Ronnenberg, Axel Stender

Patent number: 9352684Abstract: In a method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light on the trailer is actuated with an emergency brake signal during emergency braking and with a normal signal during a different driving state. The emergency brake signal causes a different actuation of the light than does the normal signal. The light can be actuated by a control signal of the towing vehicle, and the actuation state of the light can be influenced by at least one control device on the trailer. The control device detects the control signal generated by the towing vehicle and fed to the trailer to actuate the light, and analyzes the control signal. If it detects that the control signal is an emergency brake signal, it does not carry out a dedicated actuation of the light, or it effects a different actuation of the light than in other cases.Type: GrantFiled: June 9, 2012Date of Patent: May 31, 2016Assignee: WABCO GmbHInventors: Holger Barlsen, Bjorn Bleckmann, Rainer Risse, Axel Stender

Patent number: 9283932Abstract: To prevent the immobilizer for a trailer vehicle of a vehicle train from intervening when the trailer vehicle is moving in traffic, the electronic trailer braking system switches the vehicle service braking system into a “brake closed” or “brake released” state when the parking brake in the towing vehicle is actuated in closing direction or in release direction. The immobilizer is activated such that the electronic trailer braking system is only actuated by remote-control by a control device in order to switch the parking brake of the braking system permanently into the “brake closed” state when the trailer vehicle is decoupled from the vehicle train and is parked. The immobilizer is deactivated when the trailer vehicle is coupled to the vehicle train and the parking brake in the towing vehicle is engaged.Type: GrantFiled: October 31, 2013Date of Patent: March 15, 2016Assignee: WABCO GmbHInventors: Bjorn Bleckmann, Sven Gorczyca, David Kupka, Rainer Risse, Axel Stender
