Event data recorder
This vehicle is equipped with an event data recorder (EDR). The main purpose
of an EDR is to record, in certain crash or near crash-like situations, such as
an air bag deployment or hitting a road obstacle, data that will assist in understanding
how a vehicle’s systems performed. The EDR is ...
