Autonomous vehicle charging station connection
View Patent ↗A charging station can be autonomously coupled to an electric vehicle. Sensors on the vehicle determine a location of the vehicle, and the vehicle is positioned within a connection envelope. A travel path for bringing a charging connector into contact with a charging port on the vehicle can be determined, and then the travel path is autonomously carried out.
1. A method for autonomous connection of a charging station to a vehicle, the method comprising:
activating one or more locational sensors on the vehicle;
analyzing data generated by the one or more locational sensors to determine a location of the vehicle;
sending a first signal from a first sensor of the one or more locational sensors to an intelligent agent, the first signal indicating a location of the vehicle;
determining, using the intelligent agent, a first travel path of the vehicle based on the first signal;
communicating the first travel path from the intelligent agent to the vehicle;
activating one or more locational sensors on the charging station;
analyzing data generated by the one or more locational sensors on the charging station to determine a location of the charging station;
sending a second signal from a second sensor of the one or more locational sensors on the charging station to the intelligent agent, the second signal indicating a location of the charging station;
determining, using the intelligent agent, a second travel path based on the second signal; and
communicating the second travel path from the intelligent agent to the charging station;
moving the vehicle along the first travel path to position a charging port on the vehicle within a connection envelope; and
moving the charging connector along the second travel path to position a charging connector on the charging station into contact with the charging port within the connection envelope.
2. The method of claim 1 , wherein receiving the first signal from the first sensor on the vehicle comprises receiving the first signal from an on-board global positioning system.
3. The method of claim 1 , wherein the one or more locational sensors comprises at least one of ultrasonic sensors, magnetometers, and cameras.
4. The method of claim 1 , wherein activating the one or more locational sensors comprises activating at least one of ultrasonic sensors, magnetometers, and cameras.
5. The method of claim 1 , wherein the connection envelope is defined by maximum movements of the charging station along an x-axis, a y-axis, and a z-axis.
