Vehicle simulator with realistic operating feedback
First Claim
1. A system for simulating the physical sensation of a brake pedal during operation of an antilock braking system for a vehicle simulator, comprising:
- means for detecting when the brake pedal of a vehicle simulator is depressed;
means, responsive to the detecting means, for determining the activation of a simulating action of an antilock braking system; and
means, responsive to the determining means, for providing feedback indicative of an antilock braking system to the brake pedal, wherein said means for providing feedback induces motion of the brake pedal for simulating the physical movement of an actual brake pedal during antilock braking, so as to communicate through said brake pedal to a user in contact therewith a sensation representative of the sensation the user would experience during operation of an actual antilock braking system in an actual vehicle.

Abstract
A driver training system for a user of a simulated vehicle. The system includes input devices for controlling the simulated vehicle, a video display having three dimensional graphics, a computer, modeling software for determining position information based on the input devices, atmospheric effects software to simulate time-of-day and weather conditions, and realistic operating feedback software for simulating on the input devices the feedback normally experienced with operating the vehicle. One aspect of the preferred embodiment is a system including a low frequency speaker mounted on an enclosure adjacent to the simulation user'"'"'s seat through which road feel cues such as hitting an object are transmitted to the user in response to signals received from the computer. Another aspect of the invention is the a system for simulating the feel to the user of anti-lock brakes on a brake pedal in response to signals received the computer.
