Publication number: 20220167553Abstract: A robotic work tool system (200) comprising a robotic work tool (100) comprising at least one body part (140, 140-1, 140-2, 140-3) and at least one navigation sensor (170, 175) being configured to receive a control signal (225, 235), wherein at least one of the at least one navigation sensor (170, 175) is arranged on the at least one body part (140, 140-1, 140-2, 140-3). The robotic work tool (100) being configured to determine that said control signal (225, 235) is not reliably received and in response thereto rotate at least one of the at least one body part (140, 140-1, 140-2, 140-3) comprising at least one of the at least one navigation sensor (170, 175) in a first direction to attempt to regain reliable reception of the control signal (225, 235).Type: ApplicationFiled: March 30, 2020Publication date: June 2, 2022Inventors: Johan Rogö, Magnus Bergenholm, Jonas Holgersson, Martin Joelsson

Patent number: 11195346Abstract: The present disclosure relates to an articulated self-propelled robotic tool 1 with first and second platforms 3, 7, each comprising a wheel set 5, 9 driven by motors. A link arrangement connects the first platform to the second platform at a turning axis 11. A driving error is determined by recording a driving input to the motors and a resulting movement parameter, comparing the resulting movement with an estimated resulting movement which is based on the driving input. Slip is detected using the driving error.Type: GrantFiled: June 7, 2019Date of Patent: December 7, 2021Assignee: Husqvarna ABInventors: Magnus Bergenholm, Johan Rogö, Lars Ederfors

Patent number: 10031566Abstract: Described are an on board unit (OBU) and a method to control an OBU within a communication zone of a road side unit (RSU), said OBU can be set into an active mode and a sleep mode. Said OBU is set into sleep mode upon receiving a release command from said RSU, and the OBU electronics are shut down so no or a minimum of power is consumed, and is set into active mode when entering said communication zone. A communication unit of said OBU is thereby powered such that the OBU can communicate with said RSU. Said OBU can be set into a tracking mode by said RSU, whereby in said tracking mode at least said communication unit is shut down and a timer is activated in said OBU, such that said OBU can restart said communication unit within a specified time limit from when it is shut down.Type: GrantFiled: July 3, 2013Date of Patent: July 24, 2018Assignee: Kapsch TrafficCom ABInventors: Johan Rogö, Robert Povolny, Markus Krapfenbauer, Heinz Liebhart

Patent number: 9768972Abstract: A method for communication within a co-operative system is provided. The co-operative system comprises a plurality of communication units, which are adapted to execute a group of tasks repeatedly in a repetition cycle: acquire raw data from at least one raw data collector, process the raw data into an information package, and broadcast of the information package. The repetition cycle lasts a predetermined time period from a start of a repetition cycle, and the at least one raw data collector collects data from a global navigation satellite system (GNSS). The raw data from the GNSS comprises a global timing signal, to which said communication units synchronize. A timing of said execution of tasks is dependent of said global timing signal. An individual acquisition time for acquiring raw data from the raw data collectors is set for each of the plurality of communication units.Type: GrantFiled: March 11, 2014Date of Patent: September 19, 2017Assignee: Kapsch TrafficCom ABInventors: Fredrik Huus, Johan Rogö{umlaut over ( )}, Håkan Wennerholm

Patent number: 8396516Abstract: Embodiments of the present invention relates to a vehicle transponder comprising an active radio unit, an antenna, a wake-up unit and a power directing means which has a first port, a second port and a third port, where the power directing means is arranged to direct power from the first port to the second port and/or the third port. The antenna is connected to the first port and the second port is connected to the radio unit. Furthermore, the third port is connected both to a power detection port at the radio unit and to the wake-up unit, such that during a first mode of operation, a part of a signal that is transmitted from the radio unit to the antenna is coupled from the second port to the third port and further fed to the power detection port.Type: GrantFiled: October 4, 2011Date of Patent: March 12, 2013Assignee: Kapsch TrafficCom ABInventor: Johan Rogo
