an electronic differential lock the EDS
Introduction:
EDL English called Electronic Differential System, which is an extension of ABS, used to identify the wheels of the car is not losing ground friction, thereby slipping wheels of the vehicle control.
works
car during acceleration, when the electronic control unit determines that the wheel speed signal when one side of wheel slip, the EDS to work automatically, by the hydraulic control unit to brake the appropriate wheel strength, thereby improving the adhesion utilization on the other side of the drive wheel, to improve the capability 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.
Function
EDS works easier to understand. Because differential rotation allows the wheels on both sides of the drive shaft at different speeds, if one side of the drive shaft of the wheel slip or floating, will cause the other side of the wheel completely out of power, when the electronic differential lock EDS system by ABS a sensor automatically detects each wheel due to the wheel slip or the rotational speed of the floating generating different phenomena, will be braked by a wheel side slip ABS system, thereby acting effectively to the non-slipping side driving force wheels, automobile ensure a smooth start.
When the normal running condition of the vehicle, electronic differential lock stop action. The drive shaft when the vehicle 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, the EDS electronic differential lock ABS system, the sensor will pass automatically detects the rotational speed of left and right wheels.
Since whenNot the same, the EDS system will be braked by a wheel side slip ABS system, thereby effectively acting to the non-slipping wheel side, to ensure a smooth start car wheel slip drive force generated by the rotational speed of a wheel on both sides. 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.
Compared with ordinary vehicles, vehicles with EDS can make better use of ground adhesion, thereby improving the operation of the vehicle, particularly on an inclined road surface, the more pronounced effect of EDS. But it has speed limit, it is activated at speeds of less than 40km / h, mainly to prevent slipping during start-up and low speeds.
