Patent number: 5877414Abstract: A method and system for generating an effective road profile for use with a computer aided vehicle design system is disclosed. The method has the steps of developing a vehicle model for a vehicle is developed and then excited with an initial drive file to produce a vehicle model response. The vehicle model response is compared to a desired response to produce an error signal, the desired response being based on vehicle dynamics data from a vehicle when driven over a road surface. A modified error signal is determined using a vehicle response model, and the modified error signal is fed into the vehicle model to produce a vehicle model response. A new error signal is iteratively determined until it is within a predetermined limit to produce a vehicle model effective road profile. Once the effective road profile has been determined, a modified vehicle model is excited with the effective road profile to produce a modified model response. The modified vehicle can thus be tested without need for a prototype.Type: GrantFiled: July 11, 1997Date of Patent: March 2, 1999Assignee: Ford Motor CompanyInventors: Yuting Rui, Fayyaz Saleem, Jianhua Zhou
