Electronic Stability Control (ESC) with Separated Rear Tirehas the potential of improving yaw stability and reducing the occurrence of a crash when a vehicle experiences a rear tire tread separation. Two instrumented 4-door, RWD SUV’s equipped with ESC were tested to evaluate the effectiveness of their ESC systems on maintaining yaw stability under these circumstances. Tests were run with the ESC engaged and then repeated with the ESC disengaged. An analysis of the data collected shows that there are significant differences in the steering input required to generate a loss of control response with and without ESC enabled. Results of Sine with Dwell testing demonstrate a significant reduction in vehicle spinout response with the ESC engaged. This will likely have a positive effect on a driver’s ability to maintain control when faced with a rear tire tread separation under real world circumstances.
