Advanced Driver Assistance Systems & Current Vehicle Systems

When servicing vehicles fitted with ADAS, you must perform both static and dynamic calibration for ensuring accurate system diagnostics for cameras and radar units.

Maintain awareness of most recent software updates and programming to preserve precision of vehicle safety features and adhere to warranty specifications.

Comprehensive logging of calibration steps is essential for warranty compliance and effective safety system verification.

Dynamic vs Static Calibration Methods

A key component of ADAS technology is ensuring precise calibration, which can be accomplished through two main methods.

Static calibration procedures is performed with the vehicle immobile, usually in a specialized workspace like a workshop. This requires a flat surface, proper illumination, and professional calibration instruments. This method provides high precision, but it requires a dedicated workspace and tends to be time-consuming. It's more rigid and requires substantial facility costs but ensures predictable performance, not influenced by weather.

On the other hand, the dynamic method, also known as mobile calibration, takes place while the vehicle is in motion. This method requires clear weather, well-defined lane markers, and specific driving speeds. You'll benefit from its flexibility, as it assesses the system in real-world conditions and requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods hinges on specific vehicle needs, OEM guidelines, and your facility's capabilities. Often, both calibrations are necessary to maintain ideal ADAS performance, specifically after services like windscreen changes or wheel balancing.

Each method requires technical knowledge and needs to be handled carefully to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems

Advanced driver assistance systems demand thorough assessment of sensing systems to guarantee optimal performance.

Initiate diagnostics with a visual inspection of sensors for obstructions and physical damage. Be sure to retrieve any stored fault codes that may indicate component issues or positioning problems. Check each component's positioning following factory guidelines.

Cameras are fundamental in identifying road elements and markings, despite having some restrictions. Adverse weather conditions can impact performance, and compromised visibility conditions can hinder operation. Address these issues through regular cleaning and maintenance.
