A new pre-crash safety system prototype developed by ZF uses an external side airbag deployed milliseconds before a collision. It provides an additional lateral crumple zone, which can help save lives and reduce occupant injury severity by up to 40%. To make this possible, ZF has networked the airbags to the vehicle's sensor systems and developed algorithms that are capable of determining if a crash is imminent and decide whether or not to deploy the airbag.
