an electronic brake force distribution EBV
electronic brake force distribution system after EBV ABS braking system further auxiliary safety devices; may be considered as a subsystem of the ABS system. Currently used on only a very small part of the car, such as: Volvo, Audi A6 cars.
Function EBV electronic brake force distribution system that when the ABS system failure, the brake pressure regulator can be substituted, to achieve the braking force is electronically controlled automatic assignment to ensure that when the ABS electronic brake failure can call assigned emergency functions and start the ABS / EDS warning light to avoid an impact on traffic safety due to operational factors used to brake the driver. This system is generally an electronic differential lock (EDS) supporting the use, mainly used to control the braking force of the rear wheels, if the electronic brake force distribution (EBV) fails, the brake system activates an alarm light.
works EBV electronic brake force distribution system
Usually EBV and ABS electronic control unit and a common hydraulic unit, which with the ABS system is a parallel relationship. When the ABS control circuit fails, so that the same microprocessor in the ABS function failure and EBV function is enabled, instead of ABS brake pressure control system, a signal output via the output circuit and to achieve temporary control of the rear wheel brake hydraulic pressure, to prevent wheel skidding phenomenon, while the output signal by the microprocessor and transmitted to the instrument panel in a pulsating form. Dashboard distinguish three cases: no signal, pulse signal and the continuous signal. EBV function is only a secondary function, it can not completely replace the ABS system has limitations functionality of the application, it appears to work only after the fault in the ABS system, the possibility of the hired vehicle is in motion is very small. Therefore, after the failure of the ABS system, ABS system must be timely repair and restore the ABS function, in order to secure the vehicle was adequately protected.
