Patent number: 11587331Abstract: A system for a lane keeping feature of a vehicle is provided. The lane keeping feature has a predefined safety requirement criterion for keeping the vehicle within bounds while the lane keeping feature is active. The system comprises a road estimation module and a trajectory planning module. The road estimation module is configured to receive sensor data comprising information about a surrounding environment of the vehicle, and to determine a drivable area based on the sensor data. The drivable area comprises a left boundary and a right boundary extending along a direction of travel of the vehicle, wherein each boundary comprises a plurality of points distributed along each boundary, each point being associated with a confidence level. The trajectory planning module is configured to receive the determined drivable area, and to determine a nominal trajectory for the vehicle based on the received drivable area.Type: GrantFiled: August 26, 2020Date of Patent: February 21, 2023Assignee: Zenuity ABInventors: Peter Hardå, Mathias Westlund

Patent number: 11414060Abstract: Embodiments herein relate to a method performed by an autonomous vehicle for activating an autonomous braking maneuver of the autonomous vehicle having an autonomous drive system. The autonomous vehicle detects at least one user initiated request for an autonomous braking maneuver of the vehicle when the vehicle is in a first autonomous drive mode at a speed. The autonomous braking maneuver is at least one of: speed reduction or stop. When the request has been detected, the autonomous vehicle activates the autonomous braking maneuver of the vehicle which reduces the speed and/or brakes the vehicle to a stop.Type: GrantFiled: June 22, 2018Date of Patent: August 16, 2022Assignee: VOLVO CAR CORPORATIONInventors: Mathias Westlund, Jonas Nilsson

Publication number: 20210107499Abstract: The present disclosure relates to a method for controlling a control system of a vehicle having a first driver support module (e.g. ADAS feature) and a second driver support module (e.g. “under-development” ADS feature). The first driver support module and the second driver support module are capable of operation within an overlapping operational design domain (ODD). The method includes obtaining sensor data including information about a surrounding environment of the vehicle and determining fulfilment of the overlapping ODD based on the obtained sensor data. Further, if the overlapping ODD is fulfilled, the method includes switching between a first configuration where the first driver support module is active and the second driver support module is inactive, and a second configuration where the first driver support module is inactive and the second driver support module is active.Type: ApplicationFiled: October 13, 2020Publication date: April 15, 2021Inventors: Mattias BRÄNNSTRÖM, Mathias WESTLUND, Roozbeh KIANFAR, Jonas LUNDH, Cornelis BERGER

Patent number: 9325428Abstract: A two-gate sampling system has been designed to perform sampled balanced detection of one or more input signal pairs. The present invention performs simultaneous sampling of both signals in each signal pair followed by digitization and combination of the sample pairs using software. By first sampling the signals and then combining the sampled into the corresponding balanced detected signal it is possible to avoid the bandwidth limitations and impedance problems introduced by traditional balanced detectors and electrical oscilloscopes. In particular, for optical sampling gates very high bandwidth sampling gates can be designed without any impedance issues and hence almost perfect balanced detection reconstruction can be performed for very high speed signals. Balanced detection is becoming more and more important as the new phase modulated optical data signals are introduced to the market, such as e.g. PSK, DPSK, QPSK and DQPSK. The present invention is well suited for analysis of these new types of signals.Type: GrantFiled: September 17, 2009Date of Patent: April 26, 2016Assignee: EXFO INC.Inventors: Mathias Westlund, Peter Andrekson, Henrik Sunnerud, Mats Skold

Patent number: 9106334Abstract: There are provided a method and a system for characterizing the CMRR of an ICR under test, which employ highly coherent light from two continuous-wave (CW) single-frequency lasers whose respective optical frequencies mutually differ by an offset defining an “Intermediate Frequency” (fIF) in the rf electrical baseband. The method involves the coherent mixing of light from these two lasers in the ICR under test. A “tone” in the rf electrical baseband at frequency fIF is generated by the beating of light from the two single-frequency lasers as they interfere on the photodetectors of the ICR. The resulting tone at frequency fIF in the output electrical signals of the ICR is then detected and analyzed to characterize the CMRR of the ICR.Type: GrantFiled: May 9, 2014Date of Patent: August 11, 2015Assignee: EXFO Inc.Inventors: Mathias Westlund, Henrik Sunnerud
