Forensic analysis of lane-keeping assist logs – forensic documentation of steering interventions by the lane-keeping system

Lane-keeping assistance systems intervene – either by issuing a warning or by correcting the steering – when they detect that the vehicle has unintentionally strayed from its lane, and in some cases log the times at which the system was activated and intervened.

Enquire without obligation

These logs can provide information on whether and when the system actively intervened or issued a warning prior to an incident.

Why LanCologne?

Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.

The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.

Our services

We analyse the available log data from the lane departure warning system and record the times at which it was activated and when intervention took place during the relevant study period.

Typical areas of application

•Evidence of warnings or steering manoeuvres prior to an accident
•Clarification of the system’s behaviour when the vehicle leaves its lane
•Supplementing ADAS and steering angle data analyses
•Investigation into liability in accidents involving a change of lane
•Judicial and non-judicial expert reports
•Collaboration with manufacturers and experts

This is how a lane departure warning system analysis works

Once the data has been saved, the available activation and intervention logs for the lane-keeping assist system are extracted and compared with the steering angle and other vehicle data.

Why is the lane departure warning system analysis relevant to forensic investigations?

A documented system intervention shortly before an incident can provide important clues as to the actual driving conditions and possible causes.

Even the failure of an expected intervention to take place may be forensically relevant and indicate technical limitations of the system.

Frequently Asked Questions

Does the lane departure warning system intervene every time the vehicle strays from its lane?+
Not necessarily; this depends on the system design, speed and detection conditions.
Are warnings alone, without any steering intervention, also recorded?+
For many systems, yes; this is assessed on a case-by-case basis from a technical perspective.
Could the system have been triggered incorrectly by mistake?+
This will be examined as a possible explanatory approach as part of the investigation.
