Problems solved by technology

[0005] Although the arrangement in US 7,454,841 reduces the need for an operator to manually secure a camera to each of the vehicle's wheels, the method described in US 7,454,841 is advanced over time, e.g. for performing the functions of measuring and determining wheel alignment parameters Still needs further improvement

Embodiment Construction

[0051] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness. Throughout the specification, the same reference characters refer to the same elements.

[0052] Specific reference figure 1 , depicts the vehicle 100 arranged at a service station for its maintenance. In particular, the vehicle 100 is in a wheel alignment situation in order to determine whether a wheel 102 , also referred to below as wheel arrangement 102 , requires adjustment, a so-called wheel alignment adjustment. In order to determine if a wheel is out of alignment and needs adjustment, a wheel alignment system 200 is provided.

[0053] as in figure 1 As can be seen in , the wheel al...

Abstract

The present invention relates to a method for determining wheel alignment parameters of a vehicle wheel arrangement. More particularly, when performing the method, a light pattern is projected on a surface of the vehicle wheel arrangement, whereby an image of the light pattern is acquired for determining the wheel alignment parameter.

Description

technical field [0001] The invention relates to a method for determining wheel alignment parameters of a wheel arrangement. The invention also relates to a corresponding wheel alignment system for determining wheel alignment parameters of the wheel arrangement. Background technique [0002] During the manufacture and assembly of vehicles, as well as maintenance, it is always desirable to ensure that the wheels are angled relative to each other and to the ground according to drawings and specifications. If a vehicle's wheels are angled differently and do not meet a given specification, it may be necessary to adjust the wheels. This adjustment is often referred to as wheel alignment. The purpose of wheel alignment adjustment of the wheels is to reduce tire wear and, if required, ensure that the vehicle runs straight and optimizes the way the vehicle behaves and responds while driving. The adjustments are commonly referred to as camber, caster, toe and caster. [0003] Ther...
