Patent number: 10927950Abstract: A shift-by-wire shift unit for shifting a transmission of a vehicle between R, N, D and P states includes a mono-stable selector element that can be moved in opposite directions. The transmission states R and D can be reached by moving the selector element horizontally from the mono-stable position in a first and a second, opposite direction, respectively. The shift unit also includes a separate input element for changing to transmission state N. The transmission state is changeable from D to R directly by moving the selector element in the first direction, and from R to D directly by moving the selector element in the second direction. The selector element also includes a button element, and the shift unit is arranged such that, when the vehicle is at rest and the transmission is in D or R, actuating the button element effects a change to the transmission state P.Type: GrantFiled: July 1, 2015Date of Patent: February 23, 2021Assignee: Kongsberg Automotive ABInventors: Nicolas Preisig, Andreas Persson

Patent number: 9969445Abstract: A trailer (10) and a side skirt (19), each comprising an integrated arrangement (60, 70, 80) for reducing air drag, are provided. Each arrangement (60, 70, 80) comprises means for receiving air (60) comprising at least one air inlet (6), means for ejecting air (70) comprising at least one air outlet (7) facing downwards. The means for ejecting air (70) are arranged along a lower edge (11) of the trailer cargo housing (16) and side skirt (19) respectively. The arrangement also comprises means for conveying air (80) comprising at least one air duct (8). The means for conveying air (80) extend between the air receiving means (60) and the air ejecting means (70). The arrangement (60, 70, 80) is configured to produce a screen of air from the lower edge (11) and downwards during travel. The air screen prevents air, especially side wind, from entering the undercarriage.Type: GrantFiled: February 3, 2015Date of Patent: May 15, 2018Assignee: Creo Dynamics ABInventor: Andreas Persson

Patent number: 9384669Abstract: A method for estimating, from a platform, at least one parameter of an intruder. Consecutive frames of image data at different times of the intruder utilizing at least one passive sensor are generated. A direction from the platform to the intruder is determined based on the generated consecutive frames of image data. A time period remaining until a potential collision between the platform and the intruder is estimated. An angular extent of the intruder, as viewed by the passive sensor, is estimated based on the image data. At least one of a first relative location vector to a minimum intruder associated with the intruder or a second relative location vector to a maximum intruder associated with the intruder is estimated. An arrangement for generating input data to a sense-and-avoid system on-board a platform, a computer program, a computer program product and a platform carrying the arrangement are also provided.Type: GrantFiled: December 18, 2009Date of Patent: July 5, 2016Assignee: SAAB ABInventors: Erik Petrini, Bengt-Göran Sundqvist, Andreas Persson, Johan Pellebergs

Patent number: 9334621Abstract: An eccentric shaft for a compacting machine is rotatable about a rotational axis and includes a fixed and movable eccentric mass where the movable eccentric mass cooperates with the fixed eccentric mass in one of the directions of rotation of the eccentric shaft to partly balance the fixed eccentric mass in the other rotation direction of the eccentric shaft. At least one section of the fixed eccentric mass shows a maximal radial extension (UB) in relation to the rotational axis, limited by an arc-shaped curve, which extends to a circle shape, with the diameter (D) showing a distance (A), between the point (P) on the circle-shaped curve that is located closest to the point of intersection of the rotational axis and the section plane, and the point of intersection, from 0 up to 0.1(D).Type: GrantFiled: November 17, 2014Date of Patent: May 10, 2016Assignee: Dynapac Compaction Equipment ABInventors: Andreas Persson, Hans Christensen

Publication number: 20140070979Abstract: A method for validating received positional data in vehicle surveillance applications. A signal carrying a Mode S ES message including positional data indicating an alleged position of a vehicle, transmitted from a radio source is received with a radio direction finding antenna of a receiver. A bearing from the receiver to the radio source is estimated utilizing the radio direction finding antenna and received signal. A distance between the receiver and radio source based on a time of flight for a signal travelling between the receiver and radio source at known speed is estimated with a distance measurer including primary radar, laser detector and ranger, and/or secondary surveillance radar. An estimated position of the radio source is calculated based on the estimated bearing and distance. A deviation value indicating a deviation/coincidence between the alleged position is determined according to the received and estimated position of the radio source.Type: ApplicationFiled: November 12, 2013Publication date: March 13, 2014Applicant: SAAB ABInventors: Svante Andersson, Andreas Persson
