Infrared triangulation method for locating vehicles for hands-free electric vehicle charging
First Claim
1. A vehicle comprising:
- a first emitter configured to generate a first infrared signal;
a second emitter configured to generate a second infrared signal;
a vehicle wireless communications device configured to communicate with a charging station wireless communications device;
an in-vehicle display; and
at least one controller configured to present positional information via the display, the positional information corresponding to a vehicle position detected in response to the first infrared signal and the second infrared signal being received by a charging station infrared receiver;
wherein the controller is to determine an angle of entry of the vehicle using a difference in size of the first infrared signal and the second infrared signal at the charging station infrared receiver.

Abstract
A charging system for charging a vehicle includes a charging station and a vehicle. The charging station includes a wireless charging coil, an infrared receiver oriented to receive infrared signals generated proximate the coil, and a first wireless communications device. The vehicle includes a charge plate, a first emitter configured to generate a first infrared signal, a second wireless communications device in communication with the first wireless communication device, an in-vehicle display, and at least one controller. The vehicle can include a second emitter to emit a second infrared signal. The controller is configured to present positional information via the display. The positional information corresponds to a vehicle position detected in response to the first infrared signal being received by the infrared receiver.
