The Effect of Electronic Stability Control Following a Rear Tire Tread Belt Separation 2010-01-0113

In this study, tests were performed on four different vehicles, each equipped with a version of electronic stability control (“ESC”). Tests were performed on a 2000 four door sedan, a 2002 four door sedan, a 2002 five door hatchback, and a 2003 large rear wheel drive sport utility vehicle. This selection allowed for the evaluation of different ESC systems and strategies on their ability to accommodate a separated rear tire. The steer inputs were applied to the vehicles manually by test drivers and were purposely selected to generate displacements so that the ESC systems would activate. The results of this study demonstrate that ESC systems can be overwhelmed by some steering demands when a rear tire has lost its tread. This fact does not constitute a problem with the ESC systems or the vehicles tested. It merely confirms that ESC systems will not always keep a vehicle from sliding or spinning out when a tire is disabled.
