Forensic analysis of steering angle data – Forensic documentation of steering movements

The steering angle sensor continuously monitors the position of the steering wheel and thus provides data on the actual steering movement, which can be temporarily stored on an event-by-event basis in certain control units.

This data may be relevant in determining whether, and to what extent, corrective action was taken or evasive manoeuvres were performed 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 record and analyse the available steering angle data from the relevant control units and place it within the timeline of the event under investigation.

Typical areas of application

•Reconstruction of steering manoeuvres prior to an accident
•Clarification of an evasive manoeuvre
•Supplement to ADAS and lane departure warning system analyses
•Investigation into a possible loss of control of the vehicle
•Judicial and non-judicial expert reports
•Collaboration with experts on accident reports

This is how a steering angle data analysis is carried out

Once the relevant control units have been backed up, the available steering angle data is extracted and cross-referenced with speed, braking and driver assistance system data for the relevant period.

Why is the analysis of steering angle data relevant in a forensic context?

The pattern of the steering movement provides important clues as to whether the driver actively reacted to a hazardous situation.

When combined with lane-keeping assist and ADAS data, it is possible to determine whether a steering manoeuvre was caused by the driver or by an assistance system.

Frequently Asked Questions

Is steering angle data stored permanently?+
As a rule, only short-term, event-based storage takes place; this is assessed on a case-by-case basis from a technical perspective.
Is it possible to distinguish between manual and assisted steering movements?+
In many cases, yes – by cross-referencing the log data from the relevant assistance systems.
Is steering angle analysis alone sufficient for accident reconstruction?+
Not usually; it is regarded as one component amongst others, working in conjunction with other data sources.
