  • Patent number: 11364899
    Abstract: A driving assistance system includes a sensor set, a data storage device and an output device. The sensor set observes apparent states of each road user of the plurality of road users at successive time steps, the data processor assigns a behavioral model stored in the data storage device, the data processor calculating a new maneuver distribution that is a probability distribution over a finite plurality of alternative maneuvers and a new state distribution that is a probability distribution of possible states for each alternative maneuver of the finite plurality of alternative maneuvers. The data processor determines a risk of collision of the road vehicle with another road user, based on the new maneuver and state distributions of the target road user, and outputs one or more of a driver warning signal and executes an avoidance action if the risk of collision exceeds a predetermined threshold.

  • Publication number: 20210334556
    Abstract: An electronic device for determining a semantic grid of an environment of a vehicle is provided. The electronic device is configured to: receive first image data of an optical sensor, the first image data comprising a 2D image of the environment, perform a semantic segmentation of the 2D image and project the resulting semantic image into at least one predetermined semantic plane, receive an occupancy grid representing an allocentric bird eye's view of the environment. The control device further includes a neural network configured to determine a semantic grid by fusing the occupancy grid with the at least one predetermined semantic plane.

  • Publication number: 20200189574
    Abstract: The present invention concerns a driving assistance method and system (100) for a road vehicle (1). The driving assistance system (100) comprises a sensor set (200), a data storage device (101, 102) and an output device (104, 105). The sensor set (200) observes, in a traffic scene including the road vehicle among a plurality of road users, apparent states of each road user of the plurality of road users at successive time steps. The data processor (103) assigns, to a target road user of the plurality of road users, a behavioral model stored in the data storage device (101, 102).

  • Publication number: 20190353791
    Abstract: An electronic device for a vehicle for augmenting image data of a passive optical sensor. The electronic device is configured to: receive first image data of a passive optical sensor, the first image data comprising a plurality of pixels in an image plane, receive second data of an active sensor, the passive optical sensor and the active sensor sensing the same scene outside the vehicle, the active sensor including a plurality of scan areas distributed over the scene, the second data including measurement values at returned scan areas, identify at least one cluster based on the distribution of returned scan areas, project the cluster onto the image plane, identify pixels which match with the projected cluster in the image plane, and associate the identified pixels with second data of the matching cluster. Further relates to a system and a method.

  • Publication number: 20190329763
    Abstract: The present invention concerns a driving assistance method and system (100) for a road vehicle (1). The driving assistance system (100) comprises a sensor set (101), a data storage device (102) and an an output device (104,105). The sensor set (101) detects, within a traffic scene including the road vehicle (1), a set of road users and, for each road user of said set of road users, a current state including a current speed and a current position. The data storage device (102) comprises a finite plurality of behavioral models.
