About Module 2: ADAS Components
This module introduces the core components of Advanced Driver Assistance Systems (ADAS), focusing on their function, location, and the critical role each plays in vehicle safety. From front-facing radar and LiDAR to blind spot monitoring and adaptive headlights, learners will explore how each sensor contributes to features like lane-keeping assist, emergency braking, and parking assistance. The module also covers the conditions that require recalibration of these components, and highlights real-world examples of common installation and calibration failures. By the end of this lesson, participants will have a foundational understanding of ADAS hardware and the importance of precise installation, alignment, and diagnostic procedures in modern automotive repair.
The lane departure or forward-facing camera is one of the most essential ADAS components. Mounted behind the rear-view mirror, this camera monitors lane markings, vehicles, pedestrians, and other road features.
LiDAR (Light Detection and Ranging) sensors are used for obstacle detection and pedestrian protection, especially in low-speed or stop/start driving scenarios.
Front radar is responsible for Adaptive Cruise Control (ACC), Forward Collision Warning, and Automatic Emergency Braking.
These systems detect vehicles in the driver’s blind spot or approaching from the side when reversing. They increase safety during lane changes and when exiting parking spaces.
The 360-degree camera system uses multiple cameras stitched together to provide a bird’s eye view for parking and manoeuvring in tight spaces.
Ultrasonic parking sensors assist drivers in low-speed situations, alerting them to objects close to the vehicle.
Adaptive headlights swivel with steering and adjust beam patterns to improve visibility. Matrix systems use LED segments that adjust in real-time.
Lane Watch is a passenger-side mirror-mounted camera system used to display the blind spot area on the infotainment screen when indicating or turning. While Honda popularised the term "LaneWatch," similar mirror-mounted systems are used by other manufacturers as well.
Laser scanners project infrared beams via rotating mirrors to map the environment around the vehicle.
Night vision systems enhance driver awareness in low light by detecting heat signatures ahead of the vehicle.
