Electronic Stability Control
28 videos • 188 views • by Stop the Crash ESC is the most significant advance in vehicle safety since the introduction of the seat belt and one of the most important crash avoidance systems currently available. This anti-skid technology has already helped prevent hundreds of thousands of loss of control crashes and saved tens of thousands of lives. On dry, wet, or slippery roads if the vehicle starts to skid, ESC corrects the slide by reducing engine torque and braking individual wheels to bring the vehicle back on course. The system uses sensors to continuously monitor the stability of the vehicle. When an unstable state is detected, for instance as the result of a sudden direction change, ESC responds in milliseconds and stabilises the vehicle. If the system senses oversteer (i.e. that the rear of the car is starting to drift sideways out of the turn), ESC applies the brakes to the front wheel on the outside of the turn to create a counteracting torque about the vertical axis of the vehicle. This stabilises the vehicle and turns it back onto the path intended by the driver.
