Abstract
The continuing increase of routinely available computing power now allows optimization with objective functions based on time domain simulations of vehicle dynamics. This paper uses this technique to determine the steering controls which lead to very large transient lateral load transfer. The vehicle simulation uses a yaw plane vehicle model with a very capable tire model. The steering controls to be optimized are a function of their Fourier coefficients. Examples using a SUV model illustrate that very inexpensive computing platforms are able to implement millions of time domain runs in a reasonably short time in support of the optimization. Comparisons with simulations of the NHSTA fishhook maneuver provide context for the results, which lead to simulated load transfer slightly in excess of the simulated NHTSA test. The optimized runs exhibit maximum load transfer well within the confines of a two lane highway.
