Emergency Brake Assist system senses situations where emergency braking is necessary and applies the brakes should the driver’s response not be strong or fast enough. The system judges the force and speed with which a brake pedal is depressed and activates emergency braking.
Emergency Brake Assist system forms part of the Anti-lock Braking System and Electronic Brake Force Distribution system commonly found in advanced cars. It was made mandatory in the European Union countries around 2009 due to its proven results.
Normal drivers are not programmed to respond quickly enough in panic situations necessitating emergency stops. They may not apply brake quickly enough or hard enough or not pay attention and are distracted. In such cases, the response time is not fast enough to bring the vehicle to a halt quickly enough to avoid accidents. This is where emergency brake assist systems have proved invaluable.
In taking this decision the car determines speed of the vehicle and the brake force applied by the driver.
Effectiveness of EBA system and its Challenges
The system is not without its challenges.
Because of these inherent drawbacks some manufacturers have gone one up on the system and have introduced intelligent braking that makes use of lasers, radar or video cameras rather than driver input and are, therefore, more effective.
In any case, it helps if drivers carry out test drivers simulating panic situations at regular intervals to ensure the EBA is working as needed.
