Abstract

A vehicular “black box” provides recording means by which driver action can be reviewed after an accident or collision, as well as indicating immediate vehicle disposition status to the driver. Using cameras (which may be very small), the disposition of the vehicle in its lane is determined by detecting the highway lines painted on the road.

The data is also recorded so that should an accident or collision occur, the events leading up to such an event are made available for later review and analysis.
