What Is ADAS?

Advanced driver-assistance systems (ADAS) are technological features that are designed to improve driver safety and prevent automotive accidents. ADAS utilizes sensors such as radar, sonar, lidar and cameras to perceive the world around the vehicle, and either provide critical information to the driver or take automatic action to avoid or mitigate the effects of a crash. ADAS systems are designed to increase driver safety and decrease the number and/or the severity of automotive accidents.

 

When Is ADAS Calibration Required?

Whenever an ADAS sensor’s aiming is disrupted in any way, an ADAS calibration is required. Disruption can happen during a collision, even a minor fender bender, or as a result of common services like windshield replacement, suspension repair, or wheel alignment.

  • After Minor Collision

  • Collision Repair

  • Windshield Or Side View Mirror Replacement

  • Sensor / Mounting Bracket Replacement

  • Suspension Repair

  • Wheel Alignment

  • Change In Ride Or Tire Size

  • Front Air Bag Deployment If Deflected Off Windshield

  • Related DTC Is Present

  • ADAS-Related TSBs  

 

ADAS Applications What They Are & What They Do.

ADAS sensors need to be precisely aimed and calibrated to function correctly. A sensor or camera even slightly out of alignment could result in its scanning area to be off-axis by 50 feet or more, which might cause it to miss hazards.

  • ACC (Adaptive Cruise Control)

Adjusts Vehicle Speed to Maintain a Safe Distance with Vehicles Ahead.

  • AVM (Around View Monitoring)

Provides 360-Degree, Bird’s-Eye View to Help Drivers Park More Easily.

  • LDW (Lane Departure Warning)

Warns When the Vehicle Drifts Out of Their Lane.

  • APA (Automated Parking Assist)

Provides Audible, Visual, or Haptic Obstruction Warnings During Low-Speed Parking Maneuvers.

  • LIDAR (Light Imaging Detection)

Detects Objects In Vehicle Vicinity to Create a 3D Map of Objects and Surroundings.

  • NVS (Night Vision System)

Improves a Driver’s Vision in Darkness or Poor Weather.

  • BSD (Blind Spot Detection)

Detects and Warns Driver of Vehicles in Either Driver or Passenger Rear Corners (Blind Spot).

  • PD (Pedestrian Detection)

Alerts the Driver to the Presence of a Pedestrian In Front of Their Vehicle.

  • TSR (Traffic Sign Recognition)
