Abstract Vehicle pulling is extremely frustrating and perpetually adjusting the
steering wheel while driving the vehicle is additionally very unsafe if the person
driving the vehicle gets distracted even for several seconds. The pulling issue can
begin from different underlying roots. Determination of the proper root cause(s)
among many doable choices is very important to rectify the pulling behavior.
However, the diagnostic method is very complicated to put in practice due to the
functional limitations of the manufacturing processes. In this research, we describe
possible causes and remedial actions for the resolution of a vehicle having a drift
or pull condition. The study was performed on a batch of vehicles having pulling
problems and the wheel alignment values for those vehicles were matched with the
defined values. Experiments were carried for understanding the effect of change in
the tire conicity values, tire pressure, and many other parameters like road camber
and crosswinds. We have proposed a generalized method based on our investigations
for examination and resolution of the vehicle pulling problem.
