ESP (Electronic Stabilisation Programme) detects critical situations at an early stage and takes action to help bring the vehicle safely back under control.
Electronic Stabilisation Programme - or ESP - has the ability to predict what your car is about to do. What it does ESP uses sensors to monitor the progress of your wheels. The moment they start to slip, ESP takes over by; Applying the brakes to one or more wheels. Reducing engine power if necessary. The result Skidding is stopped before it begins.
How it works ESP links to the car's electronic systems such as the Anti-lock Brakes System (ABS) and Engine Braking Control (EBC). It has sensors on the wheels and steering wheel, plus a yaw movement sensor. The ESP plays a further role utilising electronic differential lock and traction control to help correct oversteer, understeer and loss of stability of the vehicle. The result is optimum traction when rounding bends. So ESP monitors your car at all times. As soon as something unusual happens e.g. if a wheel loses grip or the car starts to slip it helps regain control by applying the brakes to each or all of the wheels, and also cutting engine power. In this way it is possible that a skid is corrected even before the driver is aware that one has started.
