  • Patent number: 11587331
    Abstract: 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.

  • Patent number: 11414060
    Abstract: 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.

  • Publication number: 20210150897
    Abstract: A control system for an ego-vehicle traveling in a first direction in a first lane on a road segment is presented. The vehicle has a driver support function for autonomously maneuvering the vehicle. The control system includes control circuitry configured to obtain sensor data including information about a surrounding environment of the vehicle. The control circuitry determines a relative velocity of at least one external vehicle traveling in a second lane adjacent to the first lane based on the obtained sensor data. Moreover, the control circuitry is configured to generate a control signal in to control an availability of the driver support function for the road segment based on the comparison in order to make the driver support function available for an occupant of the vehicle if at least one external vehicle of the external vehicle(s) has been confirmed to have a relative velocity below the maximum velocity threshold.

  • Publication number: 20210107499
    Abstract: 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.

  • Patent number: 10850742
    Abstract: A safety stoppage device for an autonomous road vehicle having at least one control network and sensor, and an autonomous drive-control unit for processing sensor and communication signals and providing control signals for lateral and longitudinal control.

  • Patent number: 9325428
    Abstract: 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.

  • Patent number: 9106334
    Abstract: 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.
