Emergency Brake Assist


Emergency Brake Assist

Emergency Brake Assist (EBA) is a safety system in motor vehicles designed to ensure maximum braking power is used in an emergency stop situation. 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. [1]

Research shows that drivers can react too slowly in emergency braking situations. Many drivers are not prepared for the relatively high efforts required for maximum braking, and 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.

EBA is designed to detect such ‘panic stops’ and apply maximum braking effort within milliseconds – quicker than the blink of an eye. It interprets braking behaviour by assessing the rate that the brake pedal is activated.

If the system identifies an emergency, it automatically initiates full braking faster than any driver can move their foot. Emergency stopping distances can be shortened, reducing the likelihood of accidents – especially the common ‘nose to tail’ incident.

An electronic system designed to recognise emergency braking operation and automatically enhance braking effort improves vehicle and occupant safety. Can reduce stopping distances by up to 70 ft (21 m) at 125 mph (201 km/h)[2]
