During heavy braking, preventing wheel lock-up helps the driver maintain steering control.
Three channel systems are equipped with a sensor for each wheel, but control the rear brakes as a single unit.
As per the technical paper published by Buschmann et al.,[5] "The job of the EBD as a subsystem of the ABS system is to control the effective adhesion utilization by the rear wheels.
EBD optimizes the brake design with regard to: adhesion utilization; driving stability; wear; temperature stress; and pedal force."
EBD may work in conjunction with ABS[6] and electronic stability control (ESC) to minimize yaw accelerations during turns.
