Pre-Crash Sensing
 
In a few tenths of a second before a crash, Autoliv's near-zone radar sensors are capable of identifying the relative speed towards an object and the estimated time of impact. The regular crash sensor is then put in alert mode.

This will enhance the detection capability and timing of existing safety systems, particularly for relatively small, narrow objects, such as a corner of another vehicle, or a pole or a lamp post. The pre-crash sensing system will be especially useful in combination with active seatbelt with their pre-pretensioning immediately before a very likely crash.
