Vehicle analysis method and system
First Claim
1. A computer implemented method of reconstructing vehicle behaviour for a vehicle that has been subject to a critical event, the method comprising:
- receiving vehicle sensor data associated with vehicle motion;
receiving a critical event notification signal, the critical event notification signal being associated with a critical event time for the critical event;
deriving, from the received vehicle sensor data, a vehicle trajectory within a time window prior and adjacent to the critical event time;
inputting data relating to the derived vehicle trajectory into a multi-body model for the vehicle to determine forces acting on components within the vehicle during the time window prior and adjacent to the critical event time; and
outputting an indication of the determined forces acting through the vehicle system.

Abstract
A computer implemented method of reconstructing vehicle behaviour for a vehicle that has been subject to a critical event, the method comprising: receiving vehicle sensor data associated with vehicle motion; receiving a critical event notification signal, the critical event notification signal being associated with a critical event time for the critical event; deriving, from the received vehicle sensor data, a vehicle trajectory within a time window prior and adjacent to the critical event time; analysing the vehicle trajectory to determine forces acting through the vehicle system; outputting a notification signal in the event that one or more of the determined forces exceeds one of more of the operating parameters of the vehicle.
