Abstract
Abstract A plurality of simulator cars each have simulated controls and simulated instruments which simulate the controls and instruments of a motor vehicle. The simulated controls are manipulated to perform vehicular functions, signals representative of the position of the simulated controls being provided to a digital computer which processes same. In response thereto, signals are provided by the digital computer to the simulated instruments. Additionally connected to the digital computer is an instructor''s console which indicates desired and actual performance of the vehicular functions and provides an indication when the percentage of correct performances of a selected function is less than a selected percentile number. In an automatic mode of operation, a view of a roadway on a film is projected upon a screen which may be viewed by students within the simulator cars. Binary coded signals from the sound track of the film provide to the computer indications of desired performance of vehicular functions associated with the roadway view. In a manual mode of operation, an image on a slide may be projected on a screen and an instructor may ask questions relating to the image, indications of the answers by the students being provided on the console. In response to correct answers, an indication thereof is provided within simulator cars where the students provided the correct answers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
213 words
A driver trainer system comprising: a simulator motor vehicle which includes simulated controls and simulated instruments corresponding to controls and instruments of a motor vehicle, whereby said controls may be manipulated to perform vehicular functions and said instruments may be observed by a student in said simulator motor vehicle, said simulator motor vehicle including means for providing function signals respectively representative of positions of said controls; console means for providing indications of actual vehicular functions performed within said simulator motor vehicle and corresponding desired performance of said vehicular functions, said console means including grade trend indicator means for providing an indication if the student''s percentage of correct performances of a selected function is less than a selected percentile number, said grade trend indicator means including percentile number selection means for providing a grade trend signal representative of a selected percentile number and vehicular function selection means for providing a selection signal representative of a selected function; and a digital computer connected to said simulator motor vehicle and said console means, said computer receiving and processing said function signals, grade trend signal and selection signal to provide signals to said simulator motor vehicle and said console means whereby excitation is provided to said simulated instruments and said indications are provided by said console means.
Claim 2
Dependent Claim
213 words
A driver trainer system comprising: a simulator motor vehicle which includes simulated controls and simulated instruments corresponding to controls and instruments of a motor vehicle, whereby said controls may be manipulated to perform vehicular functions and said instruments may be observed by a student in said simulator motor vehicle, said simulator motor vehicle including means for providing function signals respectively representative of positions of said controls; console means for providing indications of actual vehicular functions performed within said simulator motor vehicle and corresponding desired performance of said vehicular functions, said console means including grade trend indicator means for providing an indication if the student''s percentage of correct performances of a selected function is less than a selected percentile number, said grade trend indicator means including percentile number selection means for providing a grade trend signal representative of a selected percentile number and vehicular function selection means for providing a selection signal representative of a selected function; and a digital computer connected to said simulator motor vehicle and said console means, said computer receiving and processing said function signals, grade trend signal and selection signal to provide signals to said simulator motor vehicle and said console means whereby excitation is provided to said simulated instruments and said indications are provided by said console means.
Claim 3
Dependent Claim
44 words
A driver trainer according to claim 1 further including: a projector for projecting a filmed view of said roadway and providing from a sound track of said film signals representative of said desired performance of vehicular functions, said projector being connected to said computer.
Claim 4
Dependent Claim
127 words
A driver trainer according to claim 1, comprising: an accelerator pedal within said simulator motor vehicle; accelerator means connected to said accelerator pedal for providing an accelerator pedal function signal having an amplitude proportional to the depression of said accelerator pedal; a digital-to-analog converter connected to said digital computer, for providing an approximate accelerator signal in response to a signal from said computer; and a comparator connected to said accelerator means, said digital-to-analog converter, and said computer, for comparing said accelerator pedal function signal with said approximate accelerator signal and for providing to said computer a comparison signal indicative of the larger one of said accelerator signals, whereby said approximate accelerator signal is adjusted to cause a decrease in the difference in ampltudes of said accelerator signals.
Claim 5
Dependent Claim
53 words
The driver trainer system of claim 1 wherein a plurality of such simulator motor vehicles are connected to said digital computer; and said grade trend indicator means provides an indication of those simulator motor vehicles in which the percentage of correct performances of said selected function is less than said selected percentile number.
Claim 6
Dependent Claim
70 words
The driver trainer system of claim 4 wherein: said console means includes means to selectively provide indications of actual vehicular functions performed within any one of said simulator motor vehicles; and said grade trend indicator means includes segmented display lamps which, when illuminated, provide a display of designations of those simulator motor vehicles where a percentage of correct performances of a selected function is less than the selected percentile number.
Claim 7
Dependent Claim
142 words
In a system for training vehicle operators wherein actual performances of vehicular functions by students on simulated controls are monitored and compared with desired performances of said vehicular functions to determine the correctness of said actual performaNces, the improvement comprising the combination of: percentile selection means providing a range of percentile numbers from which a selected percentile number may be chosen; vehicular function of selection means providing a plurality of vehicular functions from which a selected function may be chosen; means for calculating the percentage of correct performances of a selected vehicular function for each of said students; means for comparing each student''s percentage of correct performances with a selected percentile number; and means responsive to said comparing means for providing an indication of those students whose percentage of correct performances of said selected function is less than said selected percentile number.
Claim 8
Dependent Claim
142 words
In a system for training vehicle operators wherein actual performances of vehicular functions by students on simulated controls are monitored and compared with desired performances of said vehicular functions to determine the correctness of said actual performaNces, the improvement comprising the combination of: percentile selection means providing a range of percentile numbers from which a selected percentile number may be chosen; vehicular function of selection means providing a plurality of vehicular functions from which a selected function may be chosen; means for calculating the percentage of correct performances of a selected vehicular function for each of said students; means for comparing each student''s percentage of correct performances with a selected percentile number; and means responsive to said comparing means for providing an indication of those students whose percentage of correct performances of said selected function is less than said selected percentile number.
