Electronic stability program ESC with understeer control and traction control Electronic stability control ESC This system helps you to keep control of the vehicle in critical driving condi- tions (avoiding an obstacle, loss of grip on a bend, etc.). Operating principle A sensor in the steering wheel detects the direction selected by the driver. measure the actual direction. the actual trajectory of the vehicle and corrects the trajectory if necessary by controlling the braking of certain wheels and/or engine power. In the event that the system is engaged, indicator light flashes on the instrument panel. Understeer control This system optimises the action of the ESC in the case of pronounced under- steer (loss of front axle road holding). Traction control This system helps to limit wheelspin of the drive wheels and to control the ve- hicle when pulling away accelerating or decelerating. Operating principle Using the wheel sensors, the system measures and compares the speed of the drive wheels at all times and slows down their over-rotation. If a wheel is starting to slip, the system brakes au- tomatically until the drive supplied be- comes compatible with the level of grip under the wheel again.
