Patent number: 10692372Abstract: 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.

Patent number: 9469296Abstract: A method and arrangement are described for manoeuvre generation for automated driving on a one-way road of a vehicle (e) hosting the arrangement, the host vehicle (e) further including one or more advanced driver assistance systems. A collision free reference trajectory for longitudinal and lateral movement of the host vehicle (e) is determined repeatedly, with a fix time interval, for allowing the host vehicle (e) to retain a desired velocity and maintain the host vehicle (e) in a preferred lane utilizing model predictive control and quadratic program formulation. A control scheme where the structured environment of the one-way road is exploited in order to linearly formulate collision avoidance constraints is utilized. Manoeuvre generation is performed through solving the quadratic program. The one or more advanced driver assistance systems are controlled to perform the generated manoeuvre.Type: GrantFiled: September 5, 2014Date of Patent: October 18, 2016Assignee: Volvo Car CorporationInventors: Julia Nilsson, Mohammad Ali

Patent number: 9463793Abstract: A method for transition between driving modes of a vehicle is disclosed. The driving modes include an autonomous driving (AD) mode, a partly autonomous driving (PAD) mode and a manual driving (MD) mode.
