The electronic differential lock prevents the corresponding wheel from slipping.
In very adverse road conditions, the electronic differential lock (EDS) makes starting off, accelerating and driving uphill much easier, or at least possible, thanks to it.
EDS operates automatically, i.e. without driver intervention. Using ABS sensors, the device monitors the rotation speed of the drive wheels. If the rotation speed of the drive wheels differs, (approximately 100 rpm), for example, on a road that is not completely slippery, the wheel that is slipping is braked, and the wheels with better grip receive increased traction. EDS works up to a speed of about 40 km/h (front wheel drive) or 80 km/h (all wheel drive). The regulation process is accompanied by a characteristic noise.
Moving off
When a wheel slips due to a difference in the coefficient of adhesion of the drive wheels across the width of the road surface (for example, one wheel on ice) press the accelerator pedal until the car starts moving.
Heating of the brake mechanism
EDS is switched off for a short time to prevent the disc brake of the braking wheel from overheating under unusually high load. At the same time, the car is ready for use and has the same dynamic properties as a car without EDS.
EDS is automatically switched on again immediately after the brake mechanism has cooled down.
Attention
- When accelerating on a road that is equally slippery across the entire width, for example, on ice and snow, press the accelerator pedal carefully. There is a risk of slippage of the drive wheels, despite the EDS, and thus a loss of stability when driving.
- The driving mode must always be determined by the road conditions and the specific traffic situation. The increased driving safety potential provided by EDS must not provoke dangerous risks!
