The job of the EBD as a sub-system of the ABS system is to control the effective adhesion utilization by the near wheels. The pressure of the near wheels is approximated to the ideal brake force distribution in a partial braking operation. To do so, the conventional brake design is modified in the direction of rear axle overbraking, and the components of the ABS are used. EBD reduces the strain on the hydraulic brake force proportioning valve in the vehicle. EBD optimizes the brake design with regard to: adhesion utilization, driving stability, wear, temperature stress and pedal force. Hardware: For the additional EBD function, specific anti-lock-systems do not require any additional components. All components necessary for EBD are parts of the installed ABS: sensor for wheel speeds on all wheels, inlet and outlet valves for pressure modulation of the rear wheel brakes and a microprocessor-based electronic controller. EBD control is only possible with a constant-pressure. This demonstrates a further benefit of valve concepts, which allow a constant pressure without volume throughput and hence without consuming energy or affecting the pedal action. The EBD control algorithm is part of the ABS or ABS + TCS logic.
