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 determine 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.

58. A computer-implemented method for estimating impact severity from a repair estimate for a vehicle involved in a collision, the method comprising:
-
acquiring information regarding at least one damaged component of the vehicle, said information comprising repair/replace estimate information;
obtaining benchmark data related to the vehicle based at least in part on the repair/replace estimate information; and
estimating the impact severity using the benchmark data. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66)

68. A computer-implemented method for evaluating impact severity of a vehicle involved in a collision, the method comprising:
-
acquiring information regarding at least one damaged component of the vehicle;
assigning a damage rating to the vehicle based at least in part on the acquired information;
determining a first measure of impact severity based at least partially on the damage rating;
determining another measure of impact severity independently of the damage rating; and
determining a final impact severity for the vehicle based on an analysis of the first measure and the another measure. - View Dependent Claims (69, 70, 71)

72. A computer-implemented method, comprising:
-
receiving damage information for a subject vehicle involved in an accident;
comparing the damage information to benchmark information to determine compliance with a predetermined rule; and
estimating an impact severity of the subject vehicle using the benchmark information if the comparing indicates compliance with the predetermined rule. - View Dependent Claims (73, 74, 75, 76, 77, 78, 79, 80, 81)

82. A computer-implemented method, comprising:
-
receiving a damage rating for a subject vehicle involved in an accident;
comparing the damage rating to a plurality of reference sets to determine compliance with at least one predetermined rule, the reference sets being associated with one or more reference vehicles comparable with the subject vehicle; and
estimating an impact severity of the subject vehicle using data from at least one of the reference vehicles if the comparing indicates compliance with the at least one predetermined rule. - View Dependent Claims (83, 84)
