Systems, methods, and apparatus related to guidance and alignment for an electric vehicle and charging station
First Claim
1. A device for guiding an electric vehicle, comprising:
- a sensor circuit configured to determine a location of a charging spot associated with a charging base in relation to a charging coupler of the electric vehicle; and
a processor configured to;
display a virtual indicator of the location of the charging spot in a display of a graphical user interface in a virtual three dimensional perspective view of a virtual environment as observed from a first reference point located within the electric vehicle above the charging coupler such that a second reference point on a ground surface of the virtual environment and on a longitudinal axis of the electric vehicle is mapped onto a point in the display, the second reference point representing a point at a distance from a third reference point that is a projection of a center of the charging spot onto the longitudinal axis;
adjust, as the electric vehicle moves, the virtual three dimensional perspective view such that the mapped second reference point is maintained in the display; and
transition to displaying the virtual indicator of the location of the charging spot in a virtual two dimensional top-down view based on determining that an angle between a line running through the first and second reference points and a plane parallel to the ground surface satisfies an angle threshold.

Abstract
Systems, methods, and apparatus are disclosed for guiding and aligning an electric vehicle with a charging station. In one aspect, a method of guiding an electric vehicle is provided, including determining a location of a charging spot associated to a charging base in relation to a charging coupler of the electric vehicle. The method further includes displaying an indicator of the location of the charging spot in a three dimensional perspective view, the indicator displayed for guiding a user of the electric vehicle to position a charging coupler of the electric vehicle over the charging base within a tolerance area. The method further includes transitioning to displaying the indicator of the location of the charging spot in a two dimensional top-down view based on determining that an angle between a reference point and a point on ground related to the location of the charging spot satisfies a threshold.
