EBA

Emergency brake assist (EBA) The system works by detecting the pressure applied by the driver on the brake pedal and through automatic increase of this pressure, if necessary. Because many drivers do not press the brake pedal with power in emergency situations, the braking distance is adversely affected, the system compensates for this omission based on the signal received from the accelerator pedal namely the fact that it is precipitate released.

EBA System

Called AFU (Aide au Freinage d’Urgence) in francophone countries or EBA (Emergency Brake Assist)/BAS (Braking Assistance System) in Anglo-Saxon countries this system is of paramount importance in the event of emergency braking as long as the driver does not have the necessary power to push with sufficiently high pressure on the brake pedal.

More broadly, the sensors detect an extremely rapid braking, a sudden push on the brake pedal, press which, however, is not strong enough to perform an emergency maneuver. This is the typical case of female drivers who do not have the same muscle as men drivers, but have reaction speed as good as them. At this time, the electronic brain dictates a temporary extra pressure in braking circuit, so that to compensate for the lack of power of pressing.

The system Daimler Benz was developed and Lucas/TRW in 1992.

EBA ensures that full braking force is available whenever necessary, helping to reduce stopping distances in case of emergency. In order to alert other drivers if you have to brake heavily, emergency braking warning illuminate flashing rear brake lights.

Car Braking System

Braking System

The European Commission has proposed that from 2009, all automobiles to be equipped mandatory with brake assist system, as the number of victims on the road to diminish. About 8,000 pedestrians and cyclists die each year in accidents on European roads. Brake Assist (BA or BAS) would allow saving 1,100 lives and reducing seriously injured by 46,000, according to a EU Commission study.

Brake Assist

From the Manual:

Brake Assist

During urgent braking circumstances when it is essential to depress the brake pedal with higher pressure, the brake assist system gives braking assistance, therefore improving braking overall performance.

When the brake pedal is depressed hard or depressed more quickly, the brakes apply more firmly.

NOTE

  • Once the brake pedal is depressed hard or depressed more quickly, the pedal may feel softer however the brakes will apply more firmly. This is a normal a result of the brake assist procedure and does not point out a malfunction.
  • When the brake pedal is depressed hard or depressed more quickly, a motor/pump operation noise could be heard. This is a normal effect of the brake assist and does not reveal a failure.
  • The brake assist equipment does not supersede the functionality of the vehicle’s primary braking system.
