Abstract
Methods and systems for managing a speed of a vehicle are provided. The methods and systems obtain image data from one or more vision sensors disposed onboard a vehicle. A stopping distance of the vehicle is determined based at least in part on the image data. A moving speed of the vehicle and a speed limit of the vehicle are determined. The speed limit is determined based on the stopping distance that is determined from the image data. The methods and systems control movement of the vehicle based on a difference between the moving speed of the vehicle and the speed limit of the vehicle.
Claims20
A method, comprising:
- obtaining image data from one or more vision sensors disposed onboard a vehicle;
- determining a stopping distance of the vehicle based at least in part on the image data from the vehicle;
- determining a moving speed of the vehicle and a speed limit of the vehicle, the speed limit determined based on the stopping distance that is determined from the image data from the vehicle;
- and
- controlling movement of the vehicle by enforcing one or more movement authorities preventing unwarranted movement of the vehicle into one or more pathways based on a difference between the moving speed of the vehicle and the speed limit of the vehicle.
A system, comprising:
- one or more vision sensors disposed onboard a vehicle;
- an onboard controller of the vehicle configured to obtain image data from the one or more vision sensors, determine a stopping distance of the vehicle based at least in part on the image data from the vehicle, determine a moving speed of the vehicle and a speed limit of the vehicle, the speed limit determined based on the stopping distance that is determined from the image data from the vehicle, and control movement of the vehicle by enforcing one or more movement authorities preventing unwarranted movement of the vehicle into one or more pathways based on a difference between the moving speed of the vehicle and the speed limit of the vehicle.
A method, comprising:
- obtaining image data from one or more vision sensors disposed onboard a vehicle, wherein the one or more vision sensors include one or more forward-facing vision sensors;
- determining a range of vision from the vehicle based at least in part on the image data;
- determining a stopping distance of the vehicle based at least in part on the image data from the vehicle and the range of vision;
- determining a moving speed of the vehicle and a speed limit of the vehicle, the speed limit determined based on the stopping distance and the range of vision that are determined from the image data from the vehicle;
- and
- controlling movement of the vehicle by enforcing one or more movement authorities preventing unwarranted movement of the vehicle into one or more pathways based on a difference between the moving speed of the vehicle and the speed limit of the vehicle.
