• Tachograph and speed limiter supplier Lucas Kienzle is now offering an on-board accident data recorder for light commercials which could help settle insurance claims in the event of a multiple accident The 130x110x4Omm "Black Box" contains three sensors which recqrd longitudinal and lateral acceleration plus vertical rotation at the moment of an impact. It can also confirm whether indicators, headlight or brakes are functioning, thereby helping accident investigators to build up an accurate picture of what took place before, during and after an impact.
The ADR unit has a constant 45-second recording "sweep", providing a 30-second analysis period before, and 15 second recording period after, an impact. Information stored in the ADR can be downloaded to a PC for later analysis by accident investigators.
According to Kucas Kienzle, the ADR unit "records objective facts which could help spare legal time and costs. It makes the user less reliant on witnesses." It could also help operators reduce accident premiums.
LK says the system is particularly useful in determining the blame in rear-end collisions. It cites the example of a multiple accident involving a queue of three vehicles where ADR could show whether the middle vehicle had driven into the back of lead vehicle—or been stationary and knocked into it by the third vehicle.
ADR is most suitable for light/medium commercials as a minor tail-end impact on a stationary heavy artic/drawbar might not trigger the system. For heavy commercials LK operates an accident analysis service based on the tachograph.
The ADR unit is usually mounted under the driver's seat and can operate of either a 12 or 24V electrical system. Fitting price is £400-500.
