What Is ADAS?

Advanced Driver Assistance Systems (ADAS) are a collection of electronic technologies designed to improve vehicle safety and enhance the driving experience. These systems use a combination of cameras, radar, LiDAR, and ultrasonic sensors to monitor the vehicle's environment and either warn the driver of potential hazards or automatically intervene to prevent accidents.

ADAS technology is now standard equipment in most new vehicles sold in Australia and is widely present in vehicles from the past 10 years. From basic lane departure warnings to fully autonomous emergency braking, these systems are a critical component of modern vehicle safety.

ADAS systems rely on sensors — primarily cameras, radar, and ultrasonic sensors — to perceive the vehicle's surroundings. These sensors feed data into an Electronic Control Unit (ECU), which processes the information and determines whether a warning or intervention is required.

The accuracy of these systems depends entirely on the sensors being precisely aimed and calibrated to the manufacturer's specifications. Even a small misalignment — caused by a windscreen replacement, suspension repair, or minor accident — can cause the system to operate incorrectly, potentially providing false warnings or failing to detect genuine hazards.
