About ADAS
What is ADAS?
Advanced Driver Assistance Systems (ADAS) are a collection of electronic technologies in vehicles designed to enhance driver safety and comfort by assisting with various driving tasks. ADAS systems use sensors, cameras, radar, and other data sources to detect the vehicle's surroundings and provide real-time information or automated responses to the driver. Common ADAS features include:
Adaptive Cruise Control (ACC): Automatically adjusts the vehicle’s speed to maintain a safe following distance from the vehicle ahead.
Lane Keeping Assist (LKA): Helps keep the vehicle within its lane by making small steering adjustments.
Automatic Emergency Braking (AEB): Detects potential collisions and applies the brakes to avoid or mitigate the impact.
Blind Spot Detection (BSD): Warns the driver of vehicles in their blind spot during lane changes.
Traffic Sign Recognition (TSR): Identifies and displays traffic signs such as speed limits and stop signs.
Parking Assistance: Assists with parallel and perpendicular parking through automated steering, braking, and acceleration.
ADAS systems improve road safety by reducing the likelihood of human error, providing early warnings of potential hazards, and, in some cases, taking automated actions to avoid accidents.
About ADAS
When ADAS Calibration is Necessary
Ensuring the integrity and functionality of Advanced Driver Assistance Systems (ADAS) requires periodic calibration. Here are some critical instances when ADAS calibration is recommended:
After Windshield Replacement
Reason: Many ADAS components, such as forward-facing cameras and sensors, are mounted on or near the windshield. Replacing the windshield can disturb the alignment and positioning of these components, necessitating recalibration to maintain accurate system performance.
Following a Collision
Reason: Even minor accidents can impact the alignment of ADAS sensors and cameras. Post-collision calibration ensures that all systems, including those responsible for collision avoidance and lane-keeping, are functioning correctly.
Suspension or Alignment Work
Reason: Adjustments to the vehicle’s suspension or wheel alignment can affect the calibration of ADAS components. Ensuring proper recalibration after such work is crucial for systems like adaptive cruise control and lane departure warning to operate accurately.
Sensor or Camera Replacement
Reason: Replacing any ADAS component, such as a sensor or camera, requires recalibration to ensure the new parts are correctly aligned and functioning with the existing systems.
Vehicle Modifications
Reason: Modifications to the vehicle, such as changes to the ride height, bumper, or grille, can affect the positioning and operation of ADAS components. Calibration ensures these modifications do not impair the functionality of safety systems.
Regular Maintenance Intervals
Reason: Routine calibration checks during regular maintenance can preemptively identify and correct any misalignments or issues, ensuring continuous optimal performance of ADAS features.
Dashboard Alerts or Error Messages
Reason: If the vehicle’s diagnostic system detects a problem with an ADAS component, it may trigger an alert or error message. Calibration can resolve these issues and restore proper system operation.
Post-Software Updates
Reason: After updating the vehicle’s software, calibration might be necessary to ensure that all ADAS components are properly synchronized with the latest system enhancements and adjustments.
Changes in Tire Size or Type
Reason: Alterations in tire size or type can affect the calibration of ADAS systems, particularly those that rely on wheel speed and rotation data. Calibration ensures these changes do not disrupt system accuracy.
