Abstract:
1. A method of vehicle suspension testing, the method comprising the steps of: conducting actual road testing of a vehicle including collecting data; generating a drive file from the collected data for road test simulation; changing a parameter of a suspension of the vehicle, thereby resulting in a changed vehicle; conducting initial simulated road testing of the changed vehicle using the drive file; comparing results from the simulated road testing with results from the actual road testing 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 parameter of the suspension; and conducting further simulated road testing of the changed vehicle if the acceptability criteria are met, otherwise first conducting further actual road testing of the changed vehicle to develop a new drive file for use with additional simulated road testing of the changed vehicle.
