Patent number: 10137867Abstract: A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arm. The braking plate is movable from a rest position to a braking position where contact is made with the ground, and includes a sealing rim arranged to at least partially contact the ground such that an at least partly enclosed volume is formed. The vehicle braking arrangement includes an expandable chamber formed between a lower plate, at least one connecting side wall and an upper plate, which chamber is connectable to the volume. Upon activation, the chamber's volume is expanded by movement of the lower plate away from the upper plate. Then the pressure is lowered in the volume which results in that the braking plate is pressed against the ground. In this way, a retaining force is obtained.Type: GrantFiled: April 21, 2015Date of Patent: November 27, 2018Assignee: AUTOLIV DEVELOPMENT ABInventors: Christian Svensson, Dan Bråse, Erik Rydsmo, Jan-Erik Källhammer

Patent number: 10065612Abstract: A vehicle braking arrangement includes a braking plate and a link arm arranged to connect the braking plate to a vehicle. The braking plate is movable from a rest position to a braking position where contact is made with the ground. The braking plate is arranged for a first mode of operation, corresponding to the rest position, and a second mode of operation, corresponding to the braking position. In the first mode of operation, the braking plate has a first contact area arranged to face the ground, and in the second mode of operation, the braking plate has a second contact area arranged to face the ground. The second area exceeds the first area.Type: GrantFiled: March 10, 2015Date of Patent: September 4, 2018Assignee: AUTOLIV DEVELOPMENT ABInventors: Christian Svensson, Dan Bråse, Erik Rydsmo, Jan-Erik Källhammer

Patent number: 8471911Abstract: In a night vision arrangement for a motor vehicle a camera is provided which captures an image which is subsequently displayed on a display arrangement which may be a head-up display arrangement. The camera directs light on to a beam deflector which may be constituted by a mirror which deflects the beam so that it passes along a neck on to a sensor. The camera may relatively easily be mounted in position in a motor vehicle.Type: GrantFiled: August 20, 2007Date of Patent: June 25, 2013Assignees: Autoliv Development AB, Flir Systems, Inc.Inventors: Jan-Erik Kallhammer, Dick Eriksson, Lars Karlsson, Staffan Straat

Patent number: 8346463Abstract: In at least one embodiment of the present invention a driving aid system for mounting in a road vehicle is provided. The driving aid system comprises a detection system for detecting and storing profiles of characteristics of objects around the vehicle along a road on which the vehicle is being driven. A positioning system is for providing a current position of the vehicle. Profiles of characteristics of objects are stored in relation to the detected position of the vehicle. A processing arrangement compares currently detected profiles with earlier stored profiles and, if a match between a currently detected profile and an earlier stored profile is found, then the current position of the vehicle is determined relative to an object corresponding to the earlier stored profile, and the same or other earlier stored profiles is used to predict the future surroundings of the vehicle.Type: GrantFiled: March 9, 2007Date of Patent: January 1, 2013Assignee: Autoliv Development ABInventors: Jonas Bärgman, Jan-Erik Källhammer

Patent number: 8228379Abstract: In a night vision arrangement for a motor vehicle in which a camera captures an infra-red image of the roadway in front of the vehicle, a video signal generated by the camera is processed by a signal processor so that the field of view of the image displayed by a display unit is selected in accordance with a control signal. The control signal is generated by a signal generator which is responsive to one or more parameters of the movement of the vehicle. The width of the field of view may be decreased with increasing speed. The axial direction of the field of view may be adjusted depending upon the nature of a turning movement of the vehicle.Type: GrantFiled: February 5, 2008Date of Patent: July 24, 2012Assignees: Autoliv Development AB, Flir Systems, Inc.Inventors: Jan-Erik Kallhammer, Dick Eriksson, Lars Karlsson, Staffan Straat

Patent number: 8077995Abstract: Systems and methods provide infrared camera techniques that may improve image quality or infrared camera performance over a range of varying conditions. For example, in accordance with an embodiment of the present invention, a system is disclosed that transforms data provided by an infrared camera based upon environmental conditions at the time the data was obtained. As an example, the image quality provided by the infrared camera may be improved over a range of environmental conditions by the proper transformation of the data based upon the data and/or sensor information.Type: GrantFiled: February 22, 2008Date of Patent: December 13, 2011Assignees: FLIR Systems, Inc., Autoliv Development ABInventors: Bill Terre, Joseph Kostrzewa, Jan-Erik Källhammer, Tobias Höglund

Patent number: 7025375Abstract: An air-bag arrangement provides protection for the occupant of a motor vehicle. The air-bag arrangement incorporates an airbag (50) formed by two layers (51, 52) interconnected to form a first set of chambers (53, 54, 55, 56, 57, 58), having a plurality of elongated substantially parallel chambers. A further fabric layer (61) is connected to one of the two layers (52) forming the main part of the inflatable element to define a second chamber set including two chambers (62, 63). The chambers are off-set from the adjacent chambers (54, 55, 56) defined by the first two layers (51, 52). Apertures (59, 60) provided in the layer (52) allow for the inflation of the second set of chambers (62, 63).Type: GrantFiled: December 15, 2000Date of Patent: April 11, 2006Assignee: Autoliv Development ABInventors: Norbert Drössler, Jan-Erik Kållhammer
