1. An evaluating apparatus for evaluating responses over time by a subject vehicle, said apparatus comprising:
- a sampling apparatus configured to obtain a first plurality of data samples from the vehicle; and
a processor that includes a self-organizing map (SOM), the processor is configured to input the first plurality of data samples as a first plurality of sample sets to the SOM,wherein said processor is configured to include one of the first plurality of data samples in more than one of the first plurality of sample sets, andwherein said processor is configured to train the SOM to remember normal data from the first plurality of sample sets by recognizing normal interrelationships among the first plurality of data samples.

Abstract
A method of evaluating whether a vehicle under test is operating as intended. Parameters of the vehicle are sampled at a plurality of sample times to obtain a plurality of data samples. Data samples from more than one of the sample times are included in a sample set. The sample set is input to an artificial neural network (ANN). Many time-varying parameters, e.g., response times in motor vehicle systems, can be detected and evaluated.
