EDL
1, Principle
works EDS easier to understand:
[123 ] in the car during acceleration, the electronic control unit determines when the wheel speed signal when one side of the wheel slip, the EDS to work automatically, the appropriate intensity braking wheel via a hydraulic control unit, thereby improving the other side wheels attached utilization, increase capacity of the vehicle. When the vehicle driving conditions return to normal, electronic differential lock stop working. Compared with ordinary vehicles, vehicles with EDS can make better use of traction to improve the operation of the vehicle. It can be said, EDS is quite practical.
When the vehicle drive wheels are started at two different road surface friction coefficient, for example, a drive wheel in a dry asphalt road surface, the other driving wheel on the ice, then the EDS electronic differential lock automatically detects the rotational speed of left and right wheels by the sensor ABS system, when a wheel slip is generated due to the rotational speed of the wheel is not the same on both sides, the EDS system will be braked by a wheel side slip ABS system, so that the driving force acts effectively to the non-slipping wheel side, to ensure a smooth start car. However, EDS electronic differential lock which would normally be the speed limit, only the vehicle speed is below 40 km / h to start, for example, when the speed falls below 40 km on a slippery surface, EDS can also lock the slipping wheel, improve traffic safety. EDS equipment currently on the automobile market electronic differential lock mainly some high-end models such as the Audi A6, Audi A4, Passat, Jetta and Santana newly listed 3000 and other models.
