Abstract: A system and method that utilizes information relating to vehicle damage information including damaged vehicle area information, crush depth of the damaged areas information, and vehicle component-by-component damage information to estimate the relative velocities of vehicles involved in a collision. The change in velocity is estimated using a plurality of methods, and a determination is made as to which method provided a result that is likely to be more accurate, based on the damage information, and the types of vehicles involved. The results from each method may also be weighted and combined to provide a multi-method estimate of the closing velocity. The methods include using crash test data from one or more sources, estimating closing velocity based on the principals of conservation of momentum, and estimating closing velocity based on deformation energy resulting from the collision.

Abstract: A system and method enables nontechnical personnel to provide information relating to vehicle damage information via a graphical user interface of a computer system. The information provided by the user includes damaged vehicle area information, crush depth of the damaged areas information, and vehicle component-by-component damage information. This information is utilized by a &Dgr;V determination module executing on a processor to, for example, obtain respective overall vehicle damage ratings for each vehicle of two vehicles involved in a collision. The overall damage rating is obtained by applying a set of rules, based on a uniform quantification of component-by-component damage, to the subject vehicles and an identical or sister test vehicle from one or more crash tests which provide damage information.
