Autonomous Emergency Braking in the EU

• Autonomous Emergency Braking (AEB) is a collision avoidance feature that integrates state-of-the-art driver assistance systems with Electronic Stability Control (ESC)

• Experts estimate that fitting all vehicles with state-of-the-art AEB systems could cut road accident injuries by approximately 35 percent

• STOP THE CRASH

is a multi-stakeholder partnership which brings

together the expertise, experience and resources

of its public, private and civil society membership.

All are united in their shared commitment to

promote advanced vehicle safety technologies

in support of the UN’s Global Goals and the

Decade of Action for Road Safety. http://www.stopthecrash.org/
