Patent number: 11858482Abstract: A commercial vehicle includes at least one driven axle, a service brake, at least one propulsion engine, and wheels. A parking brake function of the vehicle is achieved by a bistable locking means that acts on both wheels. A first and second multi-speed gearbox having respective first and second gear stages are each activated by an actuator and coupled to the wheels. The parking brake function is achieved at least in-part by concurrently activating the first and second gear stages. A computing device is configured to activate the bistable locking means when the commercial vehicle is at a standstill and configured to send a brake request via an electronic signal to an electronic brake control unit to activate the service brake.Type: GrantFiled: October 28, 2022Date of Patent: January 2, 2024Assignee: Bendix Commercial Vehicle Systems, LLCInventors: William Plow, Zsombor Gyoerke, Janos Toth, Sven Krueger, Levente Hos, Michael Blessing, Huba Nemeth, Peter Kovacsik, Andreas Buch

Publication number: 20230192057Abstract: A parking brake apparatus is provided for a vehicle including a vehicle drive train that extends between a vehicle propulsion engine and a vehicle wheel. The parking brake apparatus comprises a wheel drum located away from the vehicle wheel and fixedly attached to a drivetrain shaft that extends along a portion of the vehicle drive train between the vehicle propulsion engine and the vehicle wheel. The parking brake apparatus also comprises activatable drum brake components disposed in an interior chamber of the wheel drum. When activated, the drum brake components apply a clamping force to the wheel drum to prevent the wheel drum and the drivetrain shaft fixedly attached thereto from rotating and thereby preventing the vehicle wheel from rotating to provide the vehicle with a parking brake functionality.Type: ApplicationFiled: December 21, 2021Publication date: June 22, 2023Applicant: KNORR BREMSE SYSTEME FÜR NUTZFAHRZEUGE GMBHInventors: William Plow, Hans Baumgartner, Zsombor Gyorke, János Tóth, Sven Krueger, Levente Hos, Michael Blessing, Andreas Buch

Publication number: 20110054756Abstract: A driving assistance system for motor vehicles, having a hazard sensor, is described that uses the brake system of the motor vehicle for the haptic warning of a driver, in that selected brake actuators of the vehicle are activated and deactivated according to a predetermined pattern. In this manner, depending on the pattern, a vibration of a steering wheel of the vehicle may be generated, as well as a response of the vehicle which simulates driving on an uneven roadway or a “washboard” roadway, or driving over an obstacle. In addition, a haptically perceivable warning signal may also be provided for a given deflection direction of the steering wheel via the difference in braking force between left and the right front wheels.Type: ApplicationFiled: April 8, 2009Publication date: March 3, 2011Inventors: Falk Hecker, Ulrich Guecker, Andreas Buch
