What is ADAS?
N
inety five percent of all new car models tested
by the European New Car Assessment Program
in 2015 were already fitted with autonomous
emergency braking.
Vehicle systems that help the driver are nothing new.
Ever since the 1960s, servo-assisted steering and
braking have made driving more comfortable and
convenient. The term "driver assistance systems" really
only caught on with the increase in ‘smart’ control.
Examples of these are Anti-lock braking systems, (ABS),
electronic stability control (ESC), windshield wipers with
rain sensors, and speed-sensitive power steering.
Advanced Driver Assistance Systems as the name
suggests are ‘even smarter’, reacting both to the driver,
and to external events, and playing an active part
almost like an independent third party in controlling the
vehicle in the interests of increased safety. Examples of
advanced driver assistance systems are:
•
Adaptive Cruise Control and Start-Stop System
•
Automatically maintains a specific distance from the
•
vehicle ahead.
•
Emergency Brake Assist Increases braking
•
appropriately to perceived conditions if the driver's
•
braking is sluggish
•
(Active) Lane Tracking Assistant Helps drivers keep
their vehicles in the same lane. May also include
an enhanced capability to optimise steering input
during quick avoidance manoeuvers, and an active
capability to apply gentle corrective measures all
by itself.
These systems all use cameras and radar sensors, which
need calibrating
•
After radar or camera replacement or dismantling/
•
installation
•
After post-accident repairs to the body geometry
•
After changes to the vehicle level at the front or
•
rear axle
•
After a suspected impact on the sensor
•
If the electronic control unit detects a calibration is
required
•
After the unit housing the sensor ( bumper,
windscreen, etc ) has been dismantled
