There are several autobrake modes, including runway overrun warning (ROW), runway overrun protection (ROP) and brake-to-vacate (BTV) introduced on the A380.

ROW and ROP detect the landing runway by comparing the aircraft’s position and flightpath vector to an airport database in the FMS.
They use aircraft weight, configuration and ground speed, along with runway condition and wind velocity entered by the crew, to determine if the aircraft can safely stop on the available runway remaining.
ROW provides warnings before landing and ROP protects the aircraft after touchdown by applying maximum braking to stop on the remaining pavement

After activating BTV, the distance available for stopping between the touchdown zone and taxiway is highlighted with symbols on the airport diagram indicating margins between both the dry and wet runway stopping points using maximum braking.
