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.
