Patent number: 10703158Abstract: Air spring strut for a motor vehicle including an air spring with a shock absorber for spring-cushioning and damping oscillations of a motor vehicle running gear assembly. The air spring includes an air spring cover and an air spring piston. An air spring bellows made of elastomeric material is clamped air-tightly between the air spring cover and the air spring piston partially delimits a working space filled with compressed air and, while forming a rolling fold, rolls on the air spring cover and/or the air spring piston. The air spring cover is embodied in two parts with a first cover part for receiving an absorber bearing and with a second cover part for fastening the air spring bellows.

Patent number: 9421839Abstract: A suspension system comprises an air supply unit and four air spring corner assemblies. The air supply unit including an ECU is fluidly connected to the air spring corner assemblies and is capable of independently adjusting the air spring corner assemblies from one another. A first pressure sensor is located at a valve block of the air supply unit. The pressure signal from the first pressure sensor is used to determine a vehicle load. A second pressure sensor proximate to at least one air spring to detect air pressure of the system at that air spring and to calibrate an air pressure for at least one of the other air springs.Type: GrantFiled: December 4, 2014Date of Patent: August 23, 2016Assignee: Continental Automotive Systems, Inc.Inventor: Christian Schallmeier

Patent number: 9415658Abstract: A method of orientating a vehicle for a potential impact includes detecting an object proximate a vehicle with at least one sensor mounted to the vehicle, identifying if the object is a pedestrian, determining a potential for a collision between the object and the vehicle with a controller mounted within the vehicle and determining a vehicle orientation for mitigating damage based on the determined potential for collision. The determined vehicle orientation includes at least an independent determination of a ride height for each corner of the vehicle. The method further includes actuating a suspension component to move each corner of the vehicle to the determined ride height for that corner independent of the other corners of the vehicle to place the vehicle in an orientation determined to mitigate damage and injury. A controller provides the independent determination of a ride height for each corner of the vehicle.Type: GrantFiled: September 23, 2015Date of Patent: August 16, 2016Assignee: Continental Automotive Systems, Inc.Inventors: Sunny Makkar, Christian Schallmeier

Patent number: 9370985Abstract: An air spring for air suspension system comprises a piston assembly and a damper assembly. A plurality of crush ribs are spaced apart from one another located within an internal cavity defined by the piston assembly and extending in an axial direction. A striker cap is located proximate to a first end of the damper assembly. There is a first interference fit between the damper assembly and the striker cap and there is a second interference fit between the striker cap and the crush fins, such that the piston assembly and the damper assembly are rotationally fixed relative to one another.Type: GrantFiled: January 22, 2015Date of Patent: June 21, 2016Assignee: Continental Automotive Systems, Inc.Inventors: Kranti Kiran Manga, Garrett Mark Pniewski, David Lee Hockey, Christian Schallmeier

Patent number: 9272596Abstract: A method of adjusting an air suspension system comprises detecting with a positioning system that the vehicle is approaching a park location and reporting the park location is approaching to an electronic control unit for the air suspension system. A vehicle speed is determined and compared to a predetermined speed threshold, with the electronic control unit. The electronic control unit selects a park mode for the suspensions system when the vehicle is approaching the park location and when the vehicle speed is below the predetermined threshold. Air supply for the air suspension system is controlled to adjust the corner assemblies for the air suspension system to lowered positions associated with the park mode.Type: GrantFiled: June 19, 2014Date of Patent: March 1, 2016Assignee: Continental Automotive Systems, Inc.Inventor: Christian Schallmeier
