Lane departure warning system
System which, using a camera which recognises   solid   or   broken   lines,   detects   the  
i

nvoluntary   crossing   of   longitudinal   traffic   lane  
m

arkings   on   the   ground.
To
  provide   safe   driving,   the   camera   analyses  
t

he   image   then,   if   the   driver's   attention   drops,  
t

riggers   a   warning   if   the   vehicle   drifts   over  
a

  lane   marking   (speed   higher   than   50   mph  
(

80 km/h)).
This
  system   is   particularly   useful   on   motor ways
