  • Patent number: 11860643
    Abstract: A system for controlling a plurality of autonomous vehicles on a mine site comprises a centralized platform configured to store an inventory list of vehicles travelling on the mine site and configured to determine and communicate missions to the vehicles of a plurality of autonomous vehicles. The autonomous vehicles may comprise an interface configured to communicate with the centralized platform for receiving a predetermined mission, a trajectory control system configured to autonomously control the autonomous vehicle according to the predetermined mission, a detection system configured to detect other vehicles by evaluating sensor information received from at least one sensor of the vehicle, a collision prediction system configured to predict collisions with the other vehicles detected by the detection system, and a V2V communication interface for directly communicating with a V2V communication interface of at least one of the other vehicles on the mine site for exchanging information between the vehicles.

  • Patent number: 11703859
    Abstract: The present application provides a method for autonomously controlling a vehicle performed by a control system of the vehicle on the basis of a mission received from a mission controller, the method comprising: receiving a mission comprising a set of instructions from the mission controller; validating the mission by checking whether the mission meets a first set of requirements; executing the mission if the mission meets the first set of requirements and rejecting the mission if the mission does not meet the first set of requirements.

  • Patent number: 11242067
    Abstract: The present application relates to a vehicle comprising a vehicle control system, the vehicle control system being configured to operate the vehicle in an autonomous mode and in a manual mode, the vehicle control system comprising: a first selector switch for switching between said autonomous mode and said manual mode; a second selector switch for switching between said autonomous mode and said manual mode; and an interlock circuit configured to deactivate propulsion of the machine when the first and the second selector switch are switched to different modes.

  • Patent number: 11230273
    Abstract: The present disclosure relates to a method for autonomously controlling a vehicle performed by a vehicle control system, the vehicle control system comprising a zone control system, a collision prediction system and a braking control system, the method comprising the steps of: defining in the zone control system at least a first zone and a second zone relative to a vehicle position, predicting a collision with an obstacle with the prediction system, autonomously braking the vehicle with the braking control system in a first braking mode if the collision is predicted to occur in the first zone and braking the vehicle with the braking control system in a second braking mode if the collision is predicted to occur in the second zone.
