the driver to maintain a constant speed, com-
bined with a preset time interval to the vehi-
cle ahead.
The camera and radar unit measures the distance to
the vehicle ahead.
An adaptive cruise control can provide a more
relaxing driving experience on long journeys on
motorways and long straight main roads in
smooth traffic flows.
The driver selects the desired speed and a
time interval to the vehicle ahead. If the cam-

speed.
