Emergency brake assist

Emergency brake assist (EBA) or Brake Assist (BA or BAS) is a generic term for an automobile braking technology that increases braking pressure in an emergency. The first application was developed jointly by Daimler-Benz and TRW/LucasVarity. Research conducted in 1992 at the Mercedes-Benz driving simulator in Berlin revealed that more than 90% of drivers fail to brake with enough force when faced with an emergency.

By interpreting the speed and force with which the brake pedal is pushed, the system detects if the driver is trying to execute an emergency stop, and if the brake pedal is not fully applied, the system overrides and fully applies the brakes until the Anti-lock Braking System (ABS) takes over to stop the wheels locking up.

Overview

Many drivers are not prepared for the relatively high efforts required for maximum braking, nor are they prepared for the "buzzing" feedback through the brake pedal during ABS operation. If an emergency develops, a slow reaction and less than maximum braking input could result in insufficient time or distance to stop before an accident occurs.

Emergency brake

An emergency brake is a separate brake system in a vehicle for use in case of failure of the regular (hydraulic or air) brakes and commonly used as a parking brake in automobiles.

Emergency brake (train)

On trains, the expression emergency brake has several meanings:

The emergency brake applies considerably more braking force than the standard full-service brake. The engineer, motorman or driver will only use the emergency brake as a last resort, since it may cause damage; even with modern wheel slide protection, a train may develop wheel-flats, and the rails themselves can suffer profile damage.

Possible consequences of operation

Putting the engineer's brake handle into the emergency position may also:
