1.6.10. Electronic blocking of differential (EDS)
Electronic blocking of differential prevents skidding of the corresponding wheel.
Under very adverse road conditions electronic blocking of differential (EDS) considerably facilitates start-off about places, dispersal and the movement uphill.
EDS works in the automatic mode, i.e. without participation of the driver. By means of sensors the ABS device controls the frequency of rotation of driving wheels. At a divergence of frequency of rotation of driving wheels (about 100 min.-1), for example, on slippery not on all width to the road, the revolving wheel is braked, and the wheels having the best coupling with the road receive the increased draft force. EDS works at a speed about no more than 40 km/h (the forward drive) or 80 km/h (four-wheel drive). Process of regulation is followed by characteristic noise.
Start-off from the place
At wheel skidding owing to difference of coefficient of coupling of driving wheels on roadbed width (for example, one wheel on ice) press an accelerator pedal until the car starts.
Heating of the brake mechanism
EDS is for a short time disconnected that the disk brake of the braking wheel at extraordinary high loading did not overheat. At the same time the car is ready for operation and has the same dynamic properties, as the car without EDS.
EDS automatically joins again right after cooling of the brake mechanism.
At dispersal on the road, equally slippery on all width, for example, in ice and snow, carefully press an accelerator pedal. There is a probability of skidding of driving wheels, despite EDS and by that violations of stability during the movement.
Fire of a control lamp of ABS can mean also malfunction of EDS. In this case as soon as possible address on the specialized enterprise.
