Reducing drive file development time for a vehicle road test simulator
A method of vehicle suspension testing includes conducting actual road testing of a vehicle including collecting data, and generating a drive file from the collected data for road test simulation. A vehicle suspension parameter is changed to result in a changed vehicle. Initial simulated road testing of the changed vehicle is conducted using the drive file, and results from the simulated and actual road testing are compared using acceptability criteria to determine whether to conduct further actual road testing of the changed vehicle before conducting further simulated road testing of the changed vehicle in response to the changed suspension parameter. Further simulated road testing of the changed vehicle is conducted if the acceptability criteria are met. Otherwise, further actual road testing of the changed vehicle is first conducted to develop a new drive file for use with additional simulated road testing of the changed vehicle.
