Abstract

Computer-based methods and systems for facilitating the inspection of a vehicle to detect the presence of prior damage and problems with previous repair are provided. Exemplary embodiments provide an inspection facilitator, which includes an inspection engine and an inspection interface. The inspection engine and inspection interface are implemented as an expert system, which directs a technician or apparatus to perform a uniform inspection process. The inspection facilitator, after receiving vehicle specific information, first directs and guides an inspection of the underbody of the vehicle to detect gross level damage or repair. The inspection facilitator then dynamically directs and guides an inspection of the outerbody of the vehicle based upon the nonconformities indicated in response to each directed inspection task. The areas to be inspected and inspection tasks are determined dynamically by comparing nonconformity input to facts and rules programmed into the inference engine of the inspection facilitator in combination with retrieved manufacturing specifications and industry standard repair procedures.
