DETROIT — Federal regulators said on Friday that 10 automakers had agreed to install automatic braking systems, which use sensors to detect potential collisions, as standard equipment in new vehicles.
But the automakers have not set a timetable for the introduction of the systems, and regulators may still seek government rules that would require the equipment as a standard feature in all cars and trucks — just as airbags were mandated a generation ago.
Anthony Foxx, the transportation secretary, said in a prepared statement that emergency braking technology could reduce traffic deaths and injuries.
