  • Patent number: 10449959
    Abstract: A method and system for navigating an autonomous vehicle is disclosed. The method comprises determining a relative velocity between the autonomous vehicle and each of one or more surrounding vehicles. Thereafter, the relative velocity associated with each of the one or more surrounding vehicles may be compared with a predefined relative speed threshold to identify a plurality of vehicles-of-interest from the one or more surrounding vehicles. An area bounded by the plurality of vehicles-of-interest may then be determined as a current navigable space for the autonomous vehicle. Subsequently, a future navigable space for the autonomous vehicle may be predicted based on a predicted velocity of the plurality of vehicles-of-interest and a predicted distance to the plurality of vehicles-of-interest. The autonomous vehicle may then be navigated based on the current navigable space and the future navigable space.

  • Publication number: 20190302780
    Abstract: Disclosed subject matter relates to vehicle navigation system that performs a method for generating safe navigation path in real-time for safe navigation of vehicle. A path generating system associated with the vehicle may receive a pre-generated navigation path, between source point and destination point. Further, the path generating system may determine uneven points and boundary points on road using sensors configured in the vehicle, within a predetermined volumetric region. Further, a preferred side of the road may be determined and a centre path line may be shifted by a distance towards the preferred side to obtain a new centre path line. Finally, the path generating system may indicate plurality of navigation points on the new centre path line that are curve fitted to generate the safe navigation path for safe navigation of the vehicle. The safe navigation path minimizes jerks experienced by the vehicle and increases safety of vehicle.

  • Publication number: 20190258260
    Abstract: The present disclosure relates to generation of a safe navigation path for a vehicle. The safe navigation path is generated by a navigation path generation system. The said system receives a reference path comprising a source location and a destination location. Further, generates segments along one of the left boundary and a right boundary, present on either side of the reference path. Further, projects at least one of a horizontal line and a vertical line from each of the segments, to meet the opposite boundary. Further, using the horizontal line and vertical line projected from each of the segments, the navigation path generation system generates a safe navigation path along the centre, between the boundaries present on either side of the reference path. Navigation of the vehicle along the safe path ensures the safety of vehicle and people in the vehicle, when the vehicle is an autonomous or semi-autonomous vehicle.

  • Publication number: 20190250624
    Abstract: Disclosed subject matter relates to a field of telematics that performs a method for generating reference navigation path in real-time for safe navigation of vehicle. A path generation system associated with the vehicle may receive a pre-generated navigation path, between source point and destination point. Further, the path generation system may identify a plurality of values corresponding to current condition of the vehicle, for a selected segment while the vehicle is navigating along the pre-generated navigation path. Further, an angular shift of the vehicle is determined based on the current condition of the vehicle and a reference navigation path is generated for the selected segment based on the angular shift. The present disclosure eliminates need for continuous monitoring and steering angle adjustment to align the vehicle with the pre-generated navigation path, thereby reducing power consumption by the vehicle and also minimizing jerks experienced by the vehicle.

  • Publication number: 20190204839
    Abstract: Disclosed subject matter relates to a field of telematics that performs a method for generating safe navigation path for navigating a vehicle. A path generation system associated with the vehicle may receive a reference path, between source point and destination point, confined between left and right boundaries of road. Further, the path generation system may determine plurality of boundary points positioned along selected boundary and may identify a tangent for a point positioned between adjacent determined boundary points from along the selected boundary. Further, a line perpendicular to the tangent may be projected from each of the plurality of boundary points until the perpendicular line reaches other boundary. The path generation system may identify centre point on each perpendicular line and connects each centre point to venerate the safe navigation path at centre of road that minimizes jerks and ensures smooth navigation and free movement of vehicle on road.

  • Publication number: 20190204098
    Abstract: The present disclosure relates to generation of a safe navigation path for a vehicle. The safe navigation path is generated by a navigation path generation system. The navigation path generation system receives a reference path from a source location to a destination location. Further, generates scan lines from the reference path to the boundaries present on either side of the reference path. Further, the navigation path generation system generates segment along the boundaries. Further, using the generated segments the navigation path generation system generates a safe navigation path along the centre, between the boundaries present on either side of the reference path. Navigation of the vehicle along the safe path ensures the safety of the vehicle and the people in the vehicle especially when the vehicle is an autonomous or semi-autonomous vehicle.

  • Publication number: 20190187709
    Abstract: The present disclosure discloses method and an autonomous navigation system for guiding an autonomous vehicle in forward path in real-time. The method comprises instructing the vehicle to terminate autonomous steering in a forward path, on identifying an angular difference, between a current orientation of the vehicle and orientation of a generated path, to be greater than a predefined threshold value and performing estimation of a frontal area for the vehicle based on a current speed, an orientation, and a width of the vehicle, calculation of a forward turning angle based on the angular difference and a length of the frontal area and guiding vehicle to manoeuvre steer at the forward turning angle within the frontal area, for every predefined time interval, until the angular difference is less than the predefined threshold value. Thus, the present disclosure provides an efficient method for guiding autonomous vehicle in forward path in real-time.

  • Patent number: 10324473
    Abstract: The present disclosure in the field of automobile engineering is a method and system for generating a safe navigation path for navigating a driverless vehicle. A path generating system receives one or more pre-generated paths between source point and destination point and an environmental data corresponding to each pre-generated path from one or more sources in real-time. Further, the path generating system identifies one or more navigation points in real-time based on the environmental data, vehicle capability characteristics and vehicle parameters by tracing virtual rays in a preconfigured angle range up to preconfigured distance from each of one or more originating points along each of the one or more pre-generated paths. Finally, the path generating system links the navigation points based on predefined techniques to generate the safe navigation path for navigating driverless vehicle. In the present disclosure, safe navigation path is generated without usage of any sensor.
