ADAS & Modern Vehicle Technologies

When working on vehicles fitted with ADAS, technicians need to complete both static and dynamic calibration to ensure precise system diagnostics for cameras and radar units.

Maintain awareness of newest programming and software updates to preserve the accuracy of vehicle safety features and meet warranty guidelines.

Comprehensive logging of these processes is essential for meeting warranty requirements and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

A crucial aspect of ADAS technology is ensuring precise calibration, which can be accomplished through either static or dynamic methods.

Static calibration is performed with the vehicle at rest, often in a controlled setting like a workshop. The process demands a level surface, proper illumination, and professional calibration instruments. This approach offers high precision, but it necessitates a specialized facility and can be time-consuming. It's more rigid and requires substantial facility costs but ensures consistent results, not influenced by weather.

On the other hand, dynamic calibration, or on-road calibration, takes place while the vehicle is being driven. This process needs clear weather, well-defined lane markers, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in practical scenarios and needs less specific hardware. However, it depends heavily on weather and road conditions, and the performance can differ.

Deciding between these methods is based on specific vehicle needs, OEM guidelines, and your facility's capabilities. Often, both calibrations are required to maintain ideal ADAS performance, especially after services like glass installations or wheel balancing.

Each method demands technical knowledge and must be executed precisely to ensure system integrity.

ADAS Camera and Radar Diagnostics

Modern ADAS vehicles require careful diagnostic procedures for camera and radar systems to ensure optimal performance.

Begin with a visual inspection of sensors to identify any blockages or damage. Be sure to scan for diagnostic trouble codes that may indicate component issues or positioning problems. Check sensor positioning following factory guidelines.

Vision systems are essential for identifying road elements and markings, though they have constraints. Challenging environmental conditions can impact performance, along with contaminated optics or insufficient lighting could impair function. Mitigate these problems using proper maintenance protocols.

To validate these systems, initiate requirements-based testing. Set safety goals, validate functionality, and verify all elements are documented.

Next, utilize scenario-based testing, simulating dynamic traffic situations and environmental conditions to validate system responses.

For hardware, implement Hardware-in-the-Loop (HIL) testing, integrating real components to validate sensors and controllers. Enhance this with digital testing environments, replicating real-world conditions for a thorough pre-deployment check.

Active safety features like automatic emergency braking and adaptive cruise control require scrupulous validation.

Remember to verify passive systems, such as warning systems and indicators, ensuring they're reliable and effective.

Warranty Requirements and Record-Keeping

The integrity of warranties for ADAS-equipped vehicles is fundamentally tied to proper documentation. You must ensure that every ADAS system repairs and services are meticulously documented. Service records must detail all calibrations, parts replacement, and diagnostic protocols. Before and after service diagnostic scans are essential, recording your vehicle's state during maintenance.

Given the interconnected nature of ADAS with critical vehicle systems like critical driving components, all repairs necessitate careful consideration of this interconnectivity. Proper calibration documentation is essential, as even minor repairs can affect ADAS performance, necessitating precise calibration.

Service provider qualifications constitute another crucial factor. Verify that the maintenance provider documents of technical training specific to ADAS systems. Adhering to OEM specifications and using authorized equipment is essential for protecting warranty validity.

For quality control, log system functionality through computer-based diagnostics and, when appropriate, supervised driving evaluations. Document initial issues, assessment outcomes, work permissions, and final testing.

Preserve both soft and hard copies of all documentation to serve as official documentation, safeguarding against potential legal challenges and maintaining comprehensive warranty oversight.
