Euro NCAP say ' ':-
'Electronic stability control (ESC)
is an active safety technology that improves a vehicle's dynamic stability by detecting loss and supporting the regain of control of the vehicle. ESC does not protect occupants in a crash, but helps to avoid the crash in the first place.
Euro NCAP for the first time has tested the ESC performance (crabsallover says 'highly recommended videos of car skids when ESC On or Off') of all cars crash-tested in 2009, we provide this data for your viewing. 2009 was also the year when we included ESC fitment as an essential part of Euro NCAP’s assessment leading to the overall award rating. Until 2009, we carried out a yearly survey of ESC fitment across all car brands. The ESC survey for 2008 is available here.
How effective is ESC?
ESC is a proven safety system. At least 40% of fatal road accidents are the result of skidding. International studies show that ESC reduces skidding accidents between 25% and 35% depending on road conditions.How does ESC operate?
When ESC detects a loss of steering control, ESC automatically applies the brakes to help manoeuvre the vehicle where the driver intends to go. Braking is automatically applied to individual wheels depending on the situation. ESC normally consists of the electronic systems of traction control and ABS using several sensors such as steering wheel angle sensor, yaw rate sensor, lateral acceleration sensor and wheel speed sensor to monitor the vehicle’s direction of travel and the driver’s intended course. ESC cannot be retrofitted and needs to be fitted before sale.'
