A driver training system (100) for a user (102) of a simulated vehicle. The system (100) includes input devices (104-112) for controlling the simulated vehicle, a video display (122) having three-dimensional graphics, a computer (114), modeling software for determining position information based on the input devices, atmospheric effects software to simulate time-of-day and weather conditions, realistic operating feedback software for simulating on the input devices the feedback normally experienced with operating the vehicle, and recursive training software to display a previous route (180) through an environment simultaneously with a present route (192) through the environment together with associated performance data (182-188). Another aspect of the recursive training software replays either the previous route (180) or present route (192) and controls one of the input devices (112) to provide ''hands-on'' feedback to the user (102). The user (102) then incrementally and recursively maximizes parameters associated with vehicle operation skill. The preferred embodiment includes a low frequency sound system (800) having a low frequency speaker (830) mounted on an enclosure (828) adjacent to the simulation user's seat (802) through which road feel cues such as hitting an object are transmitted to the user (102) in response to signals received from the computer (114). Another aspect of the invention is a system (900) for simulating the feel to the user (102) of anti-lock brakes on a brake pedal (106) in response to signals received from the computer (114). The driver training system (100) may be embodied as a vehicle simulator.
