Abstract

A vehicle simulator containing a system for development of vehicle simulation scenarios. The vehicle simulation system includes simulated vehicle controls providing input signals to a computer, and feedback devices, including a video display, providing a user feedback on the operation and location of the simulated vehicle as it is driven through a simulated universe. One aspect of the invention is a scenario development system which uses the vehicle controls, the computer and the output devices to enable a scenario developer develop a simulation scenario which includes other programmed vehicles. The scenario developer can determine when and where the other programmed vehicles become active in a simulated universe in which the scenario takes place, as well as determine when and where the programmed vehicles leave the simulated universe. The scenario developer can also program the path of the programmed vehicles through the simulated universe by simply driving the programmed vehicles through the simulated universe using the vehicle controls and the feedback devices on the path that the scenario developer wishes the programmed vehicle to appear.
