ABSTRACT:

Proper maintenance and upkeep of automobiles is essential for ensuring a reliable drive and smooth functioning of these modern wonders. Wheel alignment is one of these imperative tests that are carried out regularly. Improper alignment of wheels can result in rapid wear & tear of the tyres, abnormal pulling towards a particular side, problems on straight line tracking and host of other problems. Eventually it can lead to catastrophic failures if left unattended.

It is at this juncture, we in this paper, intend to propose a LabView based solution for wheel alignment problems using our own indigenously built setup. Wheel alignment generally involves determination of camber, caster and toe. This setup uses Optical sensors, Programmable Automation Controllers (PAC), Stepper motors, Angular Displacement sensors, Data Acquisition Cards (DAQ) and LabView among others to estimate these parameters. We hope this setup would serve in bringing down the time required for the process in addition to making it less complicated and relatively easy to use.
