Abstract

Different types of automotive vehicles having differing age and mileage parameters are automatically inspected. The different types of vehicles are variables such as vehicle maker, model, and engine type. A programmed digital computer responds to outputs of measuring instruments for inspected engine, steering and braking responses of the vehicles. For each vehicle, the computer is supplied with data indicative of the vehicle type, the parameters and with signals indicative of the vehicle engine, steering, and braking responses. The computer responds to the program, signals and data to (a) derive extreme values for a range of acceptable values for each of the inspected engine, steering and braking responses, (b) compare the outputs of the measuring instruments indicative of the vehicle engine, steering, and braking responses, and (c) derive a malfunction signal for each engine, steering and braking response outside of the range of values therefor.
