Patent number: 12197222Abstract: Disclosed are techniques for avoiding collisions with obstacles by a vehicle, in particular an off-road vehicle. Objects are detected with sensors in a calculated projected path zone of the vehicle footprint based on a vehicle trajectory. Possible path zones on either side of the projected path zone where the vehicle could potentially go with a change in trajectory are determined. The vehicle is slowed down or stopped for objects in the projected path and is slowed less for objects within the possible path zones.Type: GrantFiled: August 1, 2022Date of Patent: January 14, 2025Assignee: Trimble Inc.Inventors: Joshua Rands, Riley Kenyon, Justin Creaby

Patent number: 12179838Abstract: A control system for controlling generation of a steering wheel overlay signal to control positioning of a host vehicle is configured to determine a first boundary of a lane of travel and a target lane position for the host vehicle in relation to the first boundary, such as a predetermined distance from the first boundary. A steering wheel overlay signal is generated, the steering wheel overlay signal comprising an intra-lane steering signal for steering the host vehicle toward the target lane position. The control system is configured to remove the steering wheel overlay signal in dependence on a velocity of the host vehicle relative to the first boundary being less than a threshold velocity. Thus, the final alignment of the host vehicle achieves the perception of travelling parallel to the boundary, whilst reducing the total intervention time.Type: GrantFiled: September 9, 2020Date of Patent: December 31, 2024Assignee: JAGUAR LAND ROVER LIMITEDInventors: Denis Fusconi, Robyn Caldwell
