Embodiment 1

[0034] Preferred embodiment 1: use the first alignment parameter and the second alignment parameter to perform lateral alignment and longitudinal alignment respectively allow

[0035] Wireless charging alignment may include alignment in two directional components, ie, "horizontal" alignment and "longitudinal" alignment. Let us assume that the vehicle has a virtual axis that extends from the nose of the vehicle to the tail of the vehicle and is parallel to the direction in which the vehicle advances or retreats (when no steering movement occurs). "Lateral" alignment refers to aligning the vehicle (or a wireless power receiver thereon) with the wireless power transmitter in a direction perpendicular to the virtual axis. "Longitudinal" alignment refers to aligning the vehicle (or a wireless power receiver thereon) with the wireless power transmitter in a direction parallel to the virtual axis.

[0036] In an embodiment, a "lateral" alignment may be performed first, wherein t...

Embodiment 2

[0039] Preferred Embodiment 2: Using a Reference Object to Provide the First Alignment Parameter

[0040] In an embodiment, the first alignment parameter module 110 may determine a first alignment parameter between the wireless power transmitter and the vehicle (or the wireless power receiver on the vehicle) using a reference object in the vicinity of the wireless power transmitter. For example, the first alignment parameter module may be configured to: determine the position of a reference object around the vehicle; determine a reference relative position between the reference object and the wireless power transmitter; position to determine a first alignment parameter describing the relative position of the wireless power transmitter relative to the vehicle (or the wireless power receiver on the vehicle).

[0041] In the above embodiments, the first alignment parameter module may include a sensor and a processor. The sensors may include a single sensor or a set of sensors ...

Abstract

The invention relates to a system, a method and a medium for wireless charging alignment. The system, the method and the medium provide wireless charging alignment information. The system includes a first alignment parameter module for providing a first alignment parameter associated with a wireless charging alignment between the vehicle to a wireless power transmitter; a second alignment parameter module to provide a second alignment parameter associated with the wireless charging alignment, where the second alignment parameter is based on a wireless power transfer strength between a wireless power receiver on the vehicle and the wireless power transmitter; and an alignment parameter selection module configured to, in response to a wireless power transfer strength between the wireless power receiver and the wireless power transmitter being greater than a predetermined value, provide guidance information associated with the wireless charging alignment based at least in part on the second alignment parameter.

Description

technical field [0001] The present disclosure relates to providing wireless charging alignment information for a vehicle. Background technique [0002] Research into wireless charging technology is becoming popular as more and more vehicles are powered by electric power. For vehicles, the key point of wireless charging is how to perform the alignment between the wireless power transmitter installed on the ground and the vehicle (or the power receiver installed on the vehicle). [0003] Several techniques have been developed for wireless charging alignment of vehicles. [0004] Some technologies place dedicated sensors on the bottom of the vehicle to provide information about the relative position of the vehicle (receiving coil) and the wireless power transmitting device. Still other technologies require additional communication / guidance systems, such as local communication systems for guiding vehicles. Still other techniques rely on a dedicated reference object designed f...
