Abstract
Abstract A simulator system for providing a realistic simulation of a racecar. The simulator systems provides a driver with substantially the same visual and auditory stimuli as would a real racecar. The physical forces experienced by the driver include steering wheel movement, chassis movement and large changes in vertical, horizontal and lateral G forces as the racecar corners around turns on sloped racetrack embankments. Since the simulator accurately simulated the forces experienced when driving a real racecar, the present invention simulator can be used to physically train drivers as well as mentally train drivers. Prior to a simulation, a driver selects a type of racecar. Every adjustable feature of the racecar selected that is capable of effecting the driving performance of the racecar is given a default value that the driver may change. As a result, the performance of the simulated racecar can be selectively adjusted to match that of a real racecar for which the driver is accustomed. Similarly, changes can be made to a racecar and the driver can become accustomed to those changes without the expense or danger of experimenting with those changes in a real racecar.
