During the validation of vehicles or components proving grounds are often used to generate well defined and repeatable loads within the vehicle. In addition, the proving ground is designed in such a way, that typical customer loads in the field should be reproducible in a highly condensed way. It consists of several lanes (tracks) with different surfaces, slopes, etc. which can be driven with different speeds or different steering and braking maneuvers.
Once representatives for the customer loading have been derived by statistical reasoning, a test schedule for the proving ground has to be found, which should reflect the customer load as close as possible. At the same time, it should be as short as possible to save testing time.
