  • Patent number: 11360475
    Abstract: Aspects of the disclosure relate to routing an autonomous vehicle. For instance, the vehicle may be maneuvered along a route in a first lane using map information identifying a first plurality of nodes representing locations within the first lane and a second plurality of nodes representing locations within a second lane different from the first lane. While maneuvering, when the vehicle should make a lane change may be determined by assessing a cost of connecting a first node of the first plurality of nodes with a second node of a second plurality of nodes. The assessment may be used to make the lane change from the first lane to the second lane.

  • Patent number: 11340617
    Abstract: Without human intervention, an autonomous mobile device (AMD) uses motors to move through a physical space along a path, controlled by computing devices processing sensor data from sensors. Electrical components such as the motors and computing devices generate heat during operation. The heat generated by the motors depends on time of operation and how hard they are being driven. The more data the computing devices process, the greater the heat generated. An overheated component may protectively shut down or fail. Internal temperature is used to constrain AMD movement. The AMD path may be planned to avoid overheating along the way and avoid arriving too hot to complete an expected or scheduled task at the destination. Speed along the path may be less than maximum speed, and the amount of data sent to the computing devices is also reduced, reducing heat generation and allowing the electrical components time to cool off.

  • Patent number: 11273920
    Abstract: A method and to a device for managing energy of a hybrid power plant of a multi-rotor aircraft during a flight. The hybrid power plant comprises a thermal engine, an electricity generator, and a plurality of electric motors, together with a plurality of electrical energy storage devices. The aircraft has a plurality of rotors driven in rotation by respective electric motors. The flight of the aircraft comprises a takeoff stage, a cruising stage, and a landing stage, the takeoff stage and the landing stage being performed solely while consuming electrical energy. The method enables an electrification ratio RElec of the flight to be calculated as a function of the amounts of electrical and thermal energy that are consumed during the takeoff, landing, and cruising stages, thereby limiting the use of the thermal engine to the least possible amount during the cruising stage, and consequently reducing the associated nuisance.
