Automatic braking systems save lives. Now they’ll need to work at 62 mph.
Regulators have ordered an expansion of the tech, but the auto industry says the upgrade won’t be easy.
Auto-braking systems, called AEB for short, use sensors including cameras, radar, and lidar to sense when a crash is about to happen and warn drivers—then automatically apply the brakes if drivers don’t respond. Auto safety experts say that if automakers (and the suppliers who build their technology) pull off more advanced automatic emergency braking, they’ll have to walk a tightrope: developing tech that avoids crashes without ballooning costs. “That is a really big concern: That as you increase the number of situations in which the system has to operate, you have more of these false warnings,” says David Kidd, a senior research scientist at the Insurance Institute for Highway Safety (IIHS), an insurance-industry-funded scientific and educational organization.
