Wireless charging of a vehicle power source
Arrangements directed to the wireless charging of a vehicle are described. A battery of a vehicle can be charged while the vehicle is traveling on a roadway. A driving environment of the vehicle can be sensed to detect a charging marker. The charging marker can provide information relating to a location of a charge transmitter located below a travel surface of the roadway. The charge transmitter can be located forward of the vehicle in the travel direction of the roadway. The location of the charge transmitter can be determined based on information obtained from the charging marker. A travel path for the vehicle can be determined based at least partially on the location of the charge transmitter so that the charge receiver is positioned in substantial charging alignment with the charge transmitter as the vehicle passes over the charge transmitters.
1. A charging system for a vehicle comprising:
a charge receiver;
a sensor configured to sense a driving environment of the vehicle to detect:
a plurality of lane markers extending along a roadway, the plurality of lane markers defining a lane boundary;
a charging marker, the charging marker providing information relating to a location of a charge transmitter located at or below a travel surface of the roadway and at least partially within the lane boundary, the charge transmitter being located forward of the vehicle in a travel direction of the roadway; and
a processor operatively connected the sensor, the processor being configured to:
determine the location of the charge transmitter based on the information obtained from the charging marker;
determine a travel path for the vehicle based at least partially on the location of the charge transmitter and the plurality of lane markers so that:
a position of the vehicle is maintained within the lane boundary defined by the plurality of lane markers; and
the charge receiver is positioned in substantial charging alignment with the charge transmitter when the vehicle passes over the charge transmitter; and
causing the vehicle to autonomously implement the travel path whereby the vehicle is continuously positioned along the travel path, and wherein the vehicle is caused to autonomously implement the travel path by autonomously executing one or more maneuvers to follow the travel path.
2. The charging system of claim 1 , wherein the charging marker is encoded, and wherein the processor is configured to obtain information from the charging marker.
3. The charging system of claim 1 , wherein the sensor is a camera.
4. The charging system of claim 1 , wherein the processor is further configured to:
present the travel path to a vehicle occupant.
5. The charging system of claim 1 , wherein the processor is further configured to:
prompt a vehicle occupant for permission to implement the travel path; and
responsive to receiving permission to implement the travel path, cause the vehicle to implement the travel path.
6. The system of claim 1 , wherein the lane boundary defines a travel lane in which the vehicle is currently operating.
7. A method of charging a battery of a vehicle while traveling on a roadway, the method comprising:
sensing a driving environment of a vehicle to detect:
a plurality of lane markers extending along a roadway, the plurality of lane markers defining a lane boundary; and
a charging marker located along the roadway, the charging marker providing information relating to a location of one or more charge transmitters embedded in the roadway, the one or more charge transmitters being located forward of the vehicle and at least partially within the lane boundary defined by the lane markers;
determining a location of the one or more charge transmitters embedded in the roadway based on information obtained from the charging marker;
determining a travel path for the vehicle based at least partially on the location of the one or more charge transmitters and the plurality of lane markers so that:
a position of the vehicle is maintained within the lane boundary defined by the plurality of lane markers; and
a charge receiver of the vehicle is positioned in substantial charging alignment with a charge transmitter of the one or more charge transmitters the vehicle passes over the charge transmitter;
causing the vehicle to autonomously implement the travel path, whereby the vehicle is continuously positioned along the travel path, and wherein causing the vehicle to autonomously implement the travel path includes autonomously executing one or more maneuvers to follow the travel path; and
charging, via the charge receiver, one or more batteries of the vehicle as the vehicle passes over the charge transmitter and continues along the determined travel path.
8. The method of claim 7 , further including:
presenting the determined travel path to a vehicle occupant.
9. The method of claim 7 , wherein causing the vehicle to autonomously implement the travel path is performed responsive to receiving an input corresponding to permission to implement the travel path.
10. The method of claim 7 , wherein the lane boundary defines a travel lane in which the vehicle is currently operating.
