As part of my thesis research in behavior-based robotics, I'm going to be building a simulated robot control system for freeway driving, and I'd like to include reasonable assumptions about automobile dynamics in the simulator. In particular, I'm interested in the following functions for typical automobiles: 1) Maximum acceleration as a function of speed 2) Maximum deceleration as a function of speed 3) Maximum change in heading as a function of speed 4) Interactions between turning and max acceleration 5) Interactions between turning and max deceleration Of course, the actual values will depend on whether you're driving a Ferrari or a Yugo, but I'm interested in the general shape of the curve for your average coupe or sedan. A subject search in our library shows scores of references on automobile industry & trade, automobile workers & labor unions, environmental effects of automobiles, social aspects of automobiles, and even a book of poetry about automobile factories, but nothing about automobile performance or dynamics.

The department of transportation (DOT) funds research in a variety of vehicle properties, i.e. dynamics and the simulation of dynamics. I have in front of me the final report of DOT contract number: DOT HS-7-01715. The report number is: DOT-HS-805-370. The report is titled: Improvement of Mathematical Models for Simulation of Vehicle Handling (Vol 7: Technical Manual for the General Simulation). Does this sound like what you need? The document is available to the U.S. public through the National Technical Information Service, Springfield, Virginia, 22161 The report is 278 pages. It is a **RIGOROUS** mathematical model. I suspect that it is more detailed than what you need. If you are interested, I may be able to provide a simplistic vehicle model, i.e. no tire model, and about 1 page of alegbra. I will have to make sure it is ok to release information before sending it. If you are interested, please e-mail me directly at: laforce@krypton.arc.nasa.gov Best, Soren LaForce

There are several insurance companies, and consultants to them, who do computerized automobile accident simulations to present as evidence in court cases. The software is probably proprietary, but they might be willing to tell you their sources for the information you want.
