The objective of this study was to implement and validate a basic, yet realistic, ESC system into the VTI simulator environment. The implemented ESC system is used in a study, where the ESC system could be turned on and off, to evaluate the benefits of an ESC system after a side impact.
The experiments consist of two parts. In part 1 the test subjects are faced with a unexpected side-swipe collision. In part two the test subject, now prepared, repeatedly experience the same forces acting on the vehicle while trying to maintain control.
This study shows that an ESC system may aid the driver in such a critical situation when the driver is unaware that a side impact will occur. With the ESC system active no driver lost control while with the system inactive there were five drivers that lost control, but deviations in initial speed give statistical difficulties, thus more tests are needed. In the case where the driver knows that an impact will occur the ESC system showed to stabilize the automobile faster and it is shown that an expected improvement in stabilization time is between 40 to 62 percent. It was also seen during this part of the scenario that 2 percent loss of control occurred with an active ESC system and 45 percent without.
