  • Patent number: 10692372
    Abstract: This disclosure relates to an apparatus and a method for road vehicle driver assistance through which it is possible to determine critical obstacles that are within a predetermined proximity of a calculated maneuver corridor of the vehicle, representative of the full vehicle extension, and determination of corresponding critical points of the vehicle calculated to come into the predetermined proximity of the identified obstacles when traversing the calculated maneuver corridor. Separate from the bird's eye image of the vehicle and its surrounding is displayed at least one image acquired from a determined best camera angle and position to navigate critical obstacles. This provides a driver of an associated road vehicle with a clear overview of a current situation and provides immediate access to detailed views of one or more critical areas to navigate.
