How does it work?

ESC works by using a number of intelligent sensors that detect loss of control. 25 times per second ESC checks the driver’s steering intention against the actual vehicle direction. When these are not in sync, and the car is starting to slide out of control, ESC intervenes by braking the relevant wheel. ESC works together with computerised anti-lock braking systems to correct oversteer (when the back of the car slides out) or understeer (when car loses grip from the front). In this way ESC helps bring the car back under control, heading the direction the driver intended.
