Under very adverse road conditions, the electronic differential lock (EDS) significantly facilitates, or only thanks to it, it generally becomes possible to start, accelerate and move uphill.
EDS works in automatic mode - i.e. without the participation of the driver. With the help of ABS sensors, the device controls the speed of the drive wheels. When the frequency of rotation of the drive wheels diverges (approx. 100 rpm), for example, on a slippery road that is not full width, the slipping wheel 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 (four-wheel drive). The regulation process is accompanied by a characteristic noise.
Starting off
When the wheel slips due to a difference in the coefficient of adhesion of the driving wheels along the width of the roadway (e.g. one wheel on ice) depress the accelerator pedal until the car starts moving.
Brake heating
The EDS is switched off for a short time to prevent the braking wheel's disc brake from overheating under unusually high loads. At the same time, the vehicle is ready for operation and has the same dynamic properties as a vehicle 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, in ice and snow, carefully press the accelerator pedal. There is a possibility of slipping of the drive wheels, despite the EDS, and thus loss of stability when driving.
- The driving mode should always be determined by the condition of the roadway and the specific traffic situation. The increased potential for traffic safety due to EDS must not lead to dangerous risks!
