There's a confusion of terms here. There's the "Emergency brake" (aka e-brake) which is a misnomer for what is actually the parking brake (not to be confused with the Park setting in an automatic transmission) or also called the hand brake for cars where this brake is a hand lever rather than an extra foot pedal. And then there's "automatic emergency braking", which is a computer-controlled automatic brake that gets applied when it detects an obstacle.
