Electronic brakeforce distribution or EBD or EBFD is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's brakes， based on road conditions， speed， loading， Always coupled with anti-lock braking systems， EBD can apply more or less braking pressure to each wheel in order to maximize stopping power whilst maintaining vehicular [1][2] Typically， the front end carries the most weight and EBD distributes less braking pressure to the rear brakes so the rear brakes do not lock up and cause a [3]How ABS worksUnder heavy braking， vehicle wheels may lock- The anti-lock braking system (ABS) monitors wheel speeds and releases pressure on individual wheel brake lines， rapidly pulsing individual brakes to prevent lock- During heavy braking， preventing wheel lock-up helps the driver maintain steering Modern ABS has four individual brake lines for each wheel， enabling different braking pressure on different road For example， less braking pressure is needed to lock a wheel on ice than a wheel which on bare If the left wheels are on asphalt and the right wheels are on ice， during an emergency stop， ABS detects the right wheels about to lock and reduces braking force on the right wheels， helping to avoid lock-up and loss of vehicle How EBD worksAs per SAE technical paper #920646 - Buschmann et "The job of the EBD as a subsystem of the ABS system is to control the effective adhesion utilization by the rear The pressure of the rear wheels is approximated to the ideal brake force distribution in a partial braking To do so， the conventional brake design is modified in the direction of rear axle overbraking， and the components of the ABS are EBD reduces the strain on the hydraulic brake force proportioning valve in the EBD optimizes the brake design with regard to: adhesion utilization; driving stability; wear; temperature stress; and pedal "EBD may work in conjunction with ABS and Electronic Stability Control ("ESC") to minimize yaw accelerations during ESC compares steering wheel angle to vehicle turning rate using a yaw rate "Yaw" is the vehicle's rotation around its vertical center of gravity (turning left or right) If the yaw sensor detects more/less yaw than the steering wheel angle should create， the car is understeering or oversteering and ESC activates one of the front or rear brakes to rotate the car back into its intended For example， if a car is making a left turn and begins to understeer (the car plows forward to the outside of the turn) ESC activates the left rear brake， which will help turn the car The sensors are so sensitive， and the actuation is so quick that the system may correct direction before the driver ABS helps prevent wheel lock-up and EBD helps apply appropriate brake force to make ESC work
